“A Futuristic and Distinctive Compact” Show
2012 Honda Civic - OverviewOverview Each generation of Civic has improved with a specific development theme in mind. The 2012 Civic embraces the fundamental concept of a “futuristic and distinctive compact,” a direction that introduces new values that reach ahead of present-day needs and elevates the experience that Civic represents. Major strides include improvements to refinement throughout, increased fuel economy on all models, the further addition of interactive technologies for personalization and convenience, along with enhancements to performance, ride and interior packaging. Civic Highlights:
Civic customers span the entire public spectrum of automotive drivers. They are high school graduates and college students just beginning their adult lives; they are families with young children; they are schoolteachers, soccer parents and professionals, environmentalists and performance enthusiasts; and they are Generation Y, baby boomers and retirees. And they live in Snow Belt states, Sunbelt states, in the Midwest and in Hawaii and Alaska. But regardless of their demographic and psychographic makeup, Honda Civic customers are tied together by one thing – they are young at heart. Because at the end of the day, beyond its myriad attributes (including safety, economy, durability, comfort and style), the Civic is fun to drive. 2012 Civic Model Lineup * Fuel economy values determined from manufacturer test results. Official 2012 EPA mileage estimates not available at time of publication. Mileage figures shown for comparison purposes only. Actual mileage may vary. The 2012 Civic model lineup is comprised of:
The Foundation of Civic Safety – Advanced safety systems include Honda-exclusive Advanced Compatibility Engineering™ (ACE)™ body structure for frontal collision energy management and vehicle-to-vehicle crash compatibility, and a long list of standard safety equipment including two-row side curtain airbags, dual-stage, multiple-threshold driver's and front passenger's airbags, driver's and front passenger's side airbags, Vehicle Stability Assist™ (VSA®), an anti-lock braking system (ABS) with Brake Assist, and a new Motion Adaptive Electric Power Steering system that helps the driver steer in the ideal direction to mitigate oversteer or understeer situations. Internal crash test information* indicates that the new Civic should achieve top marks in both the federal government's National Highway Traffic Safety Administration (NHTSA) New Car Assessment Program** and the independent Insurance Institute for Highway Safety (IIHS) designation as a “TOP SAFETY PICK.” Fun to Drive – Every Civic model is designed to be fun to drive, with a MacPherson strut front suspension, a multi-link rear suspension, and front and rear stabilizer bars. Motion-Adaptive Electric Power Steering (EPS) improves steering response at low speeds while rewarding the driver with outstanding feel at higher speeds. In addition, with EPS there is no parasitic power loss to the engine as is common with a traditional hydraulically boosted steering system – which benefits both power output and fuel economy. Standard 15-inch diameter wheels with all-season tires, 16-inch wheels on Civic EX and Civic EX-L models, and 17-inch wheels on Civic Si models (with performance-oriented summer tires available) provide a satisfying blend of ride comfort and all-weather grip. The Civic Si Sedan and Civic Si Coupe further expand the driving fun with a new, larger displacement (201 horsepower) engine and specially tuned suspension. Distinctive, Aerodynamic Styling – As a new interpretation of the current Civic's iconic "one-motion" mono-form shape, the 2012 Civic is designed to convey an even more substantial, high-energy appearance. The exterior styling of both Civic Sedan and Coupe models showcases the clean-yet-powerful body lines with sleekly angled windshields, wide stances and pronounced character lines along the profile. The look of the Civic Coupe conveys an aggressive attitude with a more angular front fascia, mesh grille and a tapered rear roofline that flows smoothly into the trunk. Hidden aerodynamic features such as flat-bottom unit-body construction, precisely placed aero strakes, and other features work together to help the Civic achieve excellent fuel-economy. Comfort, Convenience and Personalization – Crisp, smart and driver focused, the new Civic's 5-passenger interior is a careful blend of form and function, with an advanced instrument layout that is unique in its class. A “smart interface” approach divides the interior into different areas, with key instrument displays located above the steering wheel. Secondary information is located lower in the area, while a third area to the driver's right groups controls that are not essential to driving. New for 2012, the intelligent Multi-Information Display (i-MID) on all models (except Civic DX) provides a 5-inch color monitor for the display of vehicle information and audio information including album artwork (if available). Along with customizable vehicle settings, the i-MID includes the ability to upload personal wallpaper backgrounds. The Civic can be further personalized for driving with Eco Assist on all models (except Civic Si), the first time this feature has been included on any non-hybrid Honda model in America. The performance-oriented Civic Si exclusively features a new Sequential Rev-limit Indicator and a Power Monitor screen that can be displayed on the new i-MID. Durability, Quality and Reliability – For many customers the Durability, Quality and Reliability (DQR) of the Honda Civic is what keeps them returning year after year. These fine qualities – and the resale or trade-in value they engender for the Civic – become a powerful purchase incentive. Virtually every major study of vehicle residual value has shown that the Civic typically has one of the highest residual values in the industry. As an end result, a high residual or resale value makes the Civic's true cost of ownership less than many lower-priced competitors. New Technology and Features For 2012, the new Civic introduces a host of new technologies that advance fuel efficiency, comfort and convenience, and safety. Some of the key features include: All Models Civic Si Sedan and Civic Si Coupe Civic Hybrid Civic Natural Gas Civic HF Powertrain
An advanced 140-horsepower, 1.8-liter i-VTEC® engine is standard in the Civic Sedan, Civic Coupe and Civic HF, with a choice of a 5-speed manual or 5-speed automatic transmission (automatic only for Civic EX-L Coupe, Civic EX and EX-L Sedans, and Civic HF). A variant of the same 1.8-liter engine develops 110 horsepower in the compressed natural gas (CNG) powered Civic Natural Gas, which comes standard with a 5-speed automatic transmission. The performance-oriented Si model has a 201-horsepower, 2.4-liter i-VTEC® engine, matched with a close-ratio 6-speed manual transmission. And finally, the Civic Hybrid is powered by an ultra-efficient 1.5-liter i-VTEC® engine with Integrated Motor Assist® producing 110-horsepower. This is coupled to a Continuously Variable Transmission (CVT). Civic Sedan, Civic Coupe, Civic HF and Civic Natural Gas Powertrain The Civic Sedan, Civic Coupe, Civic HF and Civic Natural Gas benefit from an updated and refined version of the 1.8-liter I-4 engine that powered the previous generation Civic. The new engine has extensive changes that reduce friction, improve emissions performance and increase fuel economy. The engine is a Single Overhead Cam (SOHC) 1.8-liter inline 4-cylinder design with 16 valves, i-VTEC®, and a dual-stage intake manifold. In the Civic Sedan, Civic Coupe and Civic HF, the engine produces 140 horsepower at 6300 rpm, and 128 lb-ft. of torque at 4300 rpm. In the Civic Sedan and Coupe, the 1.8-liter engine has an estimated* EPA city/highway fuel economy rating of 28/39 miles per gallon when equipped with automatic transmission. * Based on 2012 EPA mileage estimates. Use for comparison purposes only. Do not compare to models before 2008. Your actual mileage will vary depending on how you drive and maintain your vehicle. This same powertrain in the Civic HF achieves a higher estimated* city/highway fuel economy rating of 29/41 miles per gallon with its standard 5-speed automatic transmission, primarily due to reductions in aerodynamic drag and rolling resistance. With a version of the same 1.8-liter engine, the Civic Natural Gas powertrain develops 110 horsepower and 106 lb-ft of torque. The Civic Natural Gas has an estimated* city/highway fuel economy of 27/38 miles per gallon. * Fuel economy values determined from manufacturer test results.

Civic Si Powertrain The 2012 Civic Si is powered by a new 2.4-liter inline 4-cylinder engine that is the largest and most powerful of any Civic introduced in the United States. The dual overhead cam (DOHC) engine is an all-aluminum design that uses four valves per cylinder (16 valves total), a high-performance version of the i-VTEC® system and a specially tuned high-volume intake manifold. The Civic Si produces 201 horsepower – up four horsepower from the 2.0-liter engine it replaces. The i-VTEC® "intelligent" valve-control system, new friction-reducing technologies and extensive weight control measures helps the Civic Si deliver exhilarating acceleration, improved fuel economy and low exhaust emissions. The new larger displacement engine in the Civic Si delivers peak power at a more accessible 7000 rpm compared to the previous Si engine's 7800 rpm power peak. The engine's increased displacement results in a substantial 22-percent increase in peak torque. The new 170 lb-ft rating occurs at just 4400 rpm, 1700 rpm lower than the previous engine's 139 lb-ft at 6100 rpm. Even with its increase in displacement, horsepower and torque, the 2012 Civic Si has an estimated EPA city rating of 22 mpg (up 1 mpg compared to the 2011 Civic Si) and increases highway fuel economy with a rating of 31 mpg (up 2 mpg compared to the 2011 Civic Si). In addition, the Civic Si engine meets strict Ultra-Low Emission Vehicle (ULEV-2) emissions standards. The Civic Si is available exclusively with a 6-speed manual transmission with a short-throw shifter. Designed to be compact and lightweight, the 6-speed has also been engineered to provide quick and precise shift action. The Civic Si also includes a clutch with a torsion mechanism that enhances refinement in terms of engagement and feel. Civic Si Powertrain at a Glance Engine

Civic Hybrid Powertrain Together, the gasoline engine and electric motor team to produce 110 horsepower at 5500 rpm and 127 lb-ft of torque at 1000-3500 rpm. Compared to the previous generation Civic Hybrid, the new Civic Hybrid has the same peak horsepower, but achieves it at 500 fewer rpm. The new Hybrid has gained 4 lb-ft of torque, and it is spread over a wider rpm range (between 1000 rpm to 3500 rpm) for improved performance during normal city driving. During acceleration, the engine or the engine and electric motor propel the vehicle. During sustained cruising, the gasoline engine and/or the electric motor can individually propel the vehicle. During braking, the gasoline engine deactivates and the electric motor acts as generator to replenish the Li-Ion battery pack. When the vehicle is at a stop, the engine can enter an idle-stop mode to conserve fuel and reduce emissions – and the engine remains off until the brake pedal is released. Compared to the previous Civic Hybrid, the fifth-generation Honda IMA powertrain provides improved acceleration at highway speeds, while simultaneously delivering a combined city/highway EPA-estimated fuel economy rating of 44 mpg – an increase of 3 mpg from the previous model. * Based on 2012 EPA mileage estimates.

BodyThe new 2012 Civic Sedan and Civic Coupe are the most aerodynamically and aggressively styled models in the model's history – and also the most functional and versatile in how most Civic customers like to use their cars. As in past years, both 5-passenger sedan and 5-passenger coupe body styles are available. The sedan design is sophisticated and efficient, while the coupe is more dramatic and exciting. Both are highly aerodynamic, including a sleek windshield angle with narrow A-pillars (and thinner C-pillars in the Coupe) for excellent outward visibility, numerous under-vehicle aerodynamic aids, and even low rolling-resistance tires on all models except Civic Si. Apart from the headlights, hood and front fenders, no visible exterior body panels, lights, glass, grille or bumpers are shared between the Civic Sedan and Civic Coupe. Differences between models include aggressive front grille, front and rear fascias and other elements for the Civic Si Coupe and Civic Si Sedan, and extensive aerodynamic aids for the high fuel economy Civic HF. However beneath the skin, the underlying chassis construction is the same between the Civic Sedan and Civic Coupe, except that at 105.1 inches, the wheelbase of the Civic Sedan is two inches longer than that of the Civic Coupe. Civic Sedan Design Civic Coupe Design Advanced Compatibility Engineering (ACE™) Body Structure Rigid Unit-Body Construction and Energy-Absorbing Crush Zones Increased Use of High-Strength Steel In addition, more slender A-pillars (also constructed of high-strength steel) provide a greater field of view without compromising body strength. Along with a new side mirror shape, the thinner A-pillars also help minimize wind noise at highway speeds. Aerodynamic Enhancements

Wheels and Tires
For improved fuel economy, the 2012 Civic uses new tires that are 5-percent lighter with 10-percent improvement to the Rolling Resistance Coefficient (RRC) as compared to the previous Civic's tires. Constructed of low-mass tread material, thinner sidewalls and an optimized structure, the new tires help reduce fuel consumption – all while maintaining comparable durability and projected service life. The Civic HF further reduces the rolling resistance of the tires by an additional 21-percent compared to the standard Civic tires. Interior All the shapes, textures and colors work together to create a welcoming contemporary environment that is both visually and tactilely rewarding. Everything the driver needs is close at hand and materials and finishes are as carefully selected as the equipment features. Distinct upper and lower areas of the instrument panel have their own unique materials that create visual zones that add beauty and richness. Building on the successful packaging on the previous generation, the 2012 Civic Sedan has gained a small amount of interior passenger volume and also made gains in shoulder and hip room. The Civic Coupe gains an increase in front shoulder room. Both the Sedan and Coupe are classified as compact vehicles by the Environmental Protection Agency (EPA). Interior Dimensions Though the 2012 Civic Sedan is externally the same width and length, it has gained in interior passenger volume by 3.7 cubic feet, and has more front shoulder room and additional front and rear hip room. The Civic Coupe has gained 1.2 inches in front shoulder room. Other interior dimensions are within an inch of the previous generation. Advanced Instrumentation
Steering Wheel The Civic's new 3-spoke steering wheel is a small diameter unit befitting the car's sporty character and accents the vehicle's quick-ratio steering. Civic EX-L and Si steering wheels are leather trimmed for an even sportier look and feel. All Civic models feature a manual tilt and telescope steering column adjustment to better accommodate drivers of various sizes. Civic LX and models above now include audio, i-MID and cruise control buttons. Bluetooth® HandsFreeLink® control buttons are included in all models except Civic DX, Civic LX and Civic HF. Interior Materials Interior surfaces on the 2012 Civic are designed to be pleasing to the touch, with controls that are ergonomic and operate with precision. Cloth upholstery is standard in most Civic models, with Civic EX-L receiving leather seating surfaces. Leather is also available on the Civic Hybrid. Seating Like the previous generation Civic, the 2012 model can accommodate five passengers. The two front seats have been completely redesigned with a more supportive seat construction. The Civic Coupe has deeper side bolsters than the Civic Sedan, and the Civic Si further increases lateral support with firmer side bolsters. Both front seats manually recline, and the driver's seat features a manual height adjustment control. To improve access into the rear seats on the Civic Coupe, the front passenger seat has a one-touch seatback release and slide feature. A flat rear floor improves passenger comfort by providing considerably more foot room for the middle passenger. To increase storage space, Civic DX, Civic LX and Civic HF models feature a one-piece folding rear seatback, while Civic EX, Civic EX-L, and Civic Si models feature a 60/40 split-folding rear seatback. The Civic Hybrid and Civic Natural Gas have fixed rear seatbacks. Interior Storage Climate Control Systems Civic LX and above models have air conditioning with an integrated micron air-filtration system capable of filtering nearly 100 percent of particulates that are over eight microns in size (the size of most pollen), and approximately 40 percent of particulates down to 0.3 microns (about the size of diesel emissions). The Civic Hybrid has automatic climate control with a secondary compressor, powered by a high-voltage electric motor that ensures the cabin temperature stays at the preferred level during engine idle-stop. Audio Systems Music playback is a high priority for many Civic buyers, so Honda engineers worked to provide the best audio systems in the compact class. Highlights include:

Windows, Locks and Keyless Entry SafetyThe 2012 Honda Civic includes a high level of standard safety equipment in every model. The 2012 Civic integrates Honda's most advanced safety technology including the Advanced Compatibility Engineering™ (ACE™) body structure, two-row side curtain airbags and front side airbags in every model and trim level. The ACE™ body structure enhances occupant protection and crash compatibility in frontal crashes. The ACE™ design utilizes a network of connected structural elements to distribute crash energy more evenly throughout the front of the vehicle. This enhanced frontal crash energy management helps to reduce the forces transferred to the passenger compartment and can help to more evenly disperse the forces transferred to other vehicles involved in the crash. ACE™ also increases the likelihood of the two vehicle's bumpers properly connecting during a collision– including larger and smaller vehicles and those with differing bumper heights. Every Civic incorporates side curtain airbags and front side airbags with a passenger-side Occupant Position Detection System (OPDS) as standard equipment. In addition, all seating positions include head restraints that are designed to help mitigate the severity of a neck injury in the event of a rear collision. Additional standard safety features include dual-stage, multiple-threshold front airbags, an anti-lock braking system (ABS) with Brake Assist, and front seatbelts with automatic-tensioners and load limiters. Every 2012 Civic model also features daytime running lights (DRL) and a pedestrian injury mitigation design for the front of the vehicle. The ninth-generation Civic is expected to earn top safety ratings for the driver and front passenger and rear seat passengers in both frontal and side impact crash-safety tests, as well top roll-over resistance ratings, undertaken by the National Highway Traffic Safety Administration (NHTSA). It is also anticipated to earn top safety ratings from the Insurance Institute for Highway Safety (IIHS). Manufacturing More than 95-percent of Civics are currently produced and assembled in the United States and Canada using domestic and globally sourced parts. Civic Sedan and all Civic Natural Gas models are produced at Honda Manufacturing of Indiana (HMIN). All Civic Sedan, all Civic Coupe and all Civic Si models are produced and assembled at the Honda of Canada Manufacturing plant in Alliston, Ontario. All Civic Hybrid models are produced and assembled in the Honda Motor Co., Ltd., Suzuka, Japan manufacturing facility. As the newest Honda manufacturing plant, HMIN was designed to have the smallest environmental footprint of all North American automotive facilities, and HMIN is also the third North American Honda plant to be a "zero waste-to-landfill" facility. Regarding manufacturing within the United States, Honda began assembling motorcycles in America in 1979. Honda began automobile production in the U.S. in 1982 (with the Accord) and was the first Japanese automaker to assemble products for the North American market in the United States. Civic North American production began in 1985. Warranty The 2012 Honda Civic is covered by a 3-year/36,000-mile New Vehicle Limited Warranty, a 5-year/60,000-mile Powertrain Limited Warranty, and a 5-year/unlimited-mile Corrosion Limited Warranty. Additional warranties may exist depending on the model and the state in which the vehicle is initially sold. Honda Genuine Accessories are covered by a 3-year/36,000-mile Accessory Limited Warranty when installed at the time of purchase. * Official crash test data not available at time of publication (4/20/2011). **Government star ratings are part of the National Highway Traffic Safety Administration's (NHTSA) New Car Assessment Program (www.safercar.gov). Models tested with standard side airbag. 2012 Honda Civic - Safety2012 Civic Sedan body with ACE body structure Overview The 2012 Civic exemplifies the Honda approach to safety. Every Civic incorporates as standard equipment the newest generation of Vehicle Stability Assist™ (VSA®), an Anti-lock Braking System (ABS) with Brake Assist, side-curtain airbags, front-side airbags with a passenger-side Occupant Position Detection System (OPDS) and a front seat design that can help reduce the severity of neck injury in the event of a rear collision. Similar to the previous-generation Civic, an Advanced Compatibility Engineering™ (ACE™) body structure in the front of the vehicle helps make the vehicle highly effective at absorbing and disbursing the energy of a frontal crash. Additional standard safety features include dual-stage, multiple-threshold front airbags, front seatbelts with automatic tensioning system and load limiters, and a pedestrian injury mitigation design in the front of the vehicle. Driver- and front-passenger seatbelt reminders and daytime running lights (DRL) are also standard equipment. Lower Anchors and Tethers for CHildren (LATCH) child seat mounting system is present for the outboard locations of the rear seats. Standard active safety systems
Standard passive safety systems
Advanced Compatibility Engineering™
(ACE™) Body Structure Unlike most conventional designs that direct frontal crash energy only to the lower load-bearing structures in the front end, the ACE system actively channels frontal crash energy to both upper and lower structural elements, including the floor frame rails, side sills and A-pillars. By creating specifically engineered "pathways" that help distribute these frontal impact forces through a greater percentage of the vehicle's total structure, the ACE system can more effectively route them around and away from the passenger compartment to help limit cabin deformation and further improve occupant protection. Integral to the ACE concept is its unique front polygonal main design structure. Advanced Vehicle Stability Assist™ (VSA™) with Traction Control The VSA system constantly analyzes data from six sensors that monitor wheel and vehicle speed, steering input, lateral G forces and yaw rate. VSA compares the driver's inputs with the vehicle's actual response. Whenever the actual response falls outside of a predetermined acceptable range, VSA intervenes with a corrective action. For example, if VSA detects an oversteer condition, the system may apply braking force to the outside front and rear wheels to counteract the unintended yawing effect. In the event of understeer, VSA may apply braking to the inside rear wheel while reducing engine power to help return the car to its intended course. VSA also provides a limited-slip differential effect for the front wheels by applying braking force to a slipping wheel, thereby redirecting driving force to the wheel with more traction. VSA is calibrated to function in a nearly transparent manner, and in many cases a driver will not be aware of its operation. However, any time that the system is enhancing vehicle stability, an indicator light flashes in the instrument cluster. While the driver can deactivate the VSA stability enhancement and traction-control functions via a switch located on the instrument panel, ABS remains fully operational at all times. Honda is applying a new and additional type of control algorithm to the Vehicle Stability Assist® (VSA) system for the 2012 Civic that enables more responsive handling under icy or slippery conditions. The concept for this additional algorithm is based on patented Honda know-how gained from its humanoid robotics research and development work. The conventional VSA feedback loop, which operates by comparing the actual vehicle course with the intended course based on an ideal vehicle response, is augmented by additional control applied via a secondary feedback loop. This additional feedback loop is a type of filter that in effect quickens the estimation of the intended path – based on the driver’s inputs – and acts in parallel to the conventional “actual versus intended course” stability control, and is used to augment that control. Like conventional VSA, the additional control loop also considers steering wheel angle, yaw rate, wheel speeds, throttle pedal angle, vehicle acceleration and other variables. It then lightly brakes individual wheels as needed, to predictively control the vehicle along its intended path, and is able to induce more yaw more quickly than conventional VSA on low friction roads. This advanced VSA system control loop results in faster reacting stability control and reduced transient understeer which may occur on icy or other slippery roads, compared with the previous Civic VSA system. This makes the vehicle more responsive, improving path accuracy, and enhancing the fun-to-drive character that is a trademark of Honda vehicles. Brake Assist Advanced 4-Channel ABS with Electronic Brake Distribution Dual-Stage, Multiple-Threshold Front Airbags Driver and Front Passenger Side Airbags with Front Passenger Occupant Position Detection System (OPDS) Side Curtain Airbags Seat Belts Whiplash Mitigation Front Seat Design The prior-generation Civic’s active front seat head restraints and the new Whiplash Mitigation Front Seat Design accomplish approximately the same effect. The prior model had a mechanism within the seatback that would push the head restraint up and forward to help equalize forces on an occupant during a rear crash. The new 2012 seat design accomplishes a similarly effective range of motion via the overall spring and cushion tuning of the entire seat relative to the head restraint.

R&D Facilities 2012 Honda Civic - Body and Chassis2012 Civic Sedan body and chassis Body Overview Body Highlights
Apart from the headlights, hood and front fenders, no visible exterior body panels, lights, glass, grille or bumpers are shared between the Civic Sedan and Civic Coupe. However beneath the skin, the underlying chassis construction is the same between the Sedan and Coupe, except that
the Coupe wheelbase is 1.9 inches shorter (at 103.2 inches) vs. the Sedan (at 105.1 inches). Sedan Exterior Design Concept The 2012 Civic improves on the “one-motion, mono-form design” originally introduced on the previous generation Civic by making it even sleeker and more aerodynamic, benefiting the car’s sporty appearance and its fuel economy. The one-motion design is defined by a continuous line starting near the front of the hood, extending over the cabin and continuing all the way to the trunk lid in an unbroken, single motion. Compared to the previous model, the 2012 Civic front A-pillars have been moved further forward resulting in a steeper, more aggressive windshield angle. The highest roof point comes above the head of the front passengers, which creates a coupe-like roofline that flows smoothly into the trunk. To fully express the clean and energetic design theme, surface treatment plays an important role. Both front and rear fender lines have been designed to seem to bulge out, creating a feeling of powerful, dynamic strength. More particularly, the line extending from the upper character line to the rear fender broadens into a deep shoulder line with clearly delineated, sharp edges that further enhance the feeling of dynamism. In the lower part of the body, a single character line runs the length of the side from front to rear with a slight kink towards the back, accenting the flowing side view. Compared to the previous Civic, the front part of the beltline has been lowered to increase forward visibility. Additionally, the forwardmost surface at the base of the front pillar has been covered with a piece of black trim to give the impression the glass area extends even further than it actually does, creating a pointed, sharp appearance. The rear side glass area adopts a sharp cutoff line that pulls the entire upper window line further back and ultimately adds to the more dynamic and sporty side view. More Spacious Interior Advancements in unit-body design and component integration actually increase the Civic Sedan’s passenger volume to 94.7 cu. ft., a 3.8 cu. ft. (4.1 percent) increase over the 2011 Civic Sedan’s 90.9 cu. ft. of passenger volume. The improvement is equally dramatic in the EX and EX-L models, which are equipped with a standard moonroof. These models also benefit from 3.7 cu. ft. more passenger volume, a 4.2 percent increase. As a result, from inside the new Civic looks, feels, and simply is more spacious - with improved ingress and egress as well. The new Civic Coupe has fractionally less passenger volume than the previous model - 83.2 cu. ft. for the 2012 Coupe compared to 83.7 cu. ft. for the outgoing model. Both the Sedan and Coupe remain classified as Compact vehicles by the EPA. Civic Sedan Dimensions: Standard Civic Sedan Exterior Features

Coupe Exterior Design Concept Along the Coupe bodyside, the solid-wedge design continues, with the hood, windshield and cabin forming one continuous flowing line. The windshield has the steepest rake of any Honda, and the windshield pillar and side mirror shape help minimize wind noise at highway speeds. In addition, decisive character lines along the bodyside flow upward toward the rear of the vehicle, creating a strong sense of motion even when the Coupe is at rest. In back, the high rear deck further reinforces the Coupe’s dynamic, wedge styling and allows for a larger trunk opening for easier cargo loading. A functional rear lip spoiler and 16-inch aluminum wheels on EX and EX-L models further reinforce the Coupe’s sporty appearance. Civic Si Coupe

The moonroof fully opens or closes automatically. However if the operator wishes to only partially open or close the moonroof (such as to achieve partial ventilation), a lighter touch yields full manual control. A pinch protection feature is built in, helping to ensure that the moonroof will not close if someone’s hand or arm is positioned in the path of the moonroof. If an obstruction is detected, the moonroof mechanism will reverse direction the moonroof. Windshield Wipers Cargo Area Conveniently placed latches in the trunk enable users to lower the fold-down rear seatback without having to be inside of the vehicle. The Civic EX and EX-L models add even more convenience with their 60/40 split fold-down rear seatback design, which allow the option of passenger seating and cargo storage simultaneously. All models feature a wide trunk opening and low lift-over height for easy placement and removal of items. The inside of the trunk uses a high-quality molded trunk lining. Underneath, the spare tire has a molded lining for extra storage, a feature seldom found within the compact class.

Chassis Overview Regardless of whether it is a versatile Civic Sedan or Coupe, sporty Civic Si, or efficient Civic Hybrid, Civic Natural Gas or Civic HF model, every 2012 Honda Civic is both refined and fun to drive. The suspension is tuned to provide a sporty, solid and dynamic driving experience. The standard Anti-lock Braking System (ABS) with Electronic Brake Distribution (EBD) and Brake Assist uses ventilated front discs and rear drums, or 4-wheel discs on Civic EX, EX-L and Si models. New Motion-Adaptive Electric Power Steering (EPS) offers direct-feeling and efficient steering performance, together with improved active safety. On the previous generation models, EPS application was exclusive to the Civic Si and Civic Hybrid models. 2012 Civic EX Sedan chassis Civic Chassis Highlights
The basic architecture of the suspension for the 2012 Civic is similar to the previous-generation model. Changes have been made to components to refine ride and handling, and to reduce the intrusion of noise, vibration and harshness (NVH) into the passenger cabin. Compared to the previous-generation Civic, the most significant change to the platform is the additional use of high strength steel (up 10 percent to 55 percent in the Sedan and up 30 percent to 56 percent in the Coupe). As well, a slightly shorter wheelbase (reduced 1.2 inches in the Sedan to 105.1 inches and reduced 1.1 inches in the Coupe to 103.2 inches) increases the feeling of agility as the car rotates around a geometrically shorter distance while turning. This improves overall maneuverability and the Civic’s fun-to-drive character. But at the same time, the overall length, width and height are the same as previous models, with increased interior roominess. The result is a more responsive car that is also roomier inside.

A long 105.1-inch wheelbase for the Civic Sedan and 103.2-inch wheelbase for the Civic Coupe, wide front and rear track dimensions, advanced suspension design along with features such as VSA® and Motion Adaptive Electric Power Steering (EPS) on all models contribute to the Civic’s confident handling. Specially tuned independent MacPherson strut front and multi-link rear suspension provides a nimble and fun driving experience - while also providing the dynamic safety for which all Honda vehicles are known. Front and Rear Suspension The MacPherson strut front suspension is engineered to provide engaging performance and a responsive feel for the driver. Specially tuned bushings along with performance-calibrated geometry ensure optimal wheel alignment while turning for a solid and smooth handling feel. All models of Civic use a 17 mm diameter tubular front stabilizer bar, with the exception of the Civic Si that uses a more performance minded 18 mm tubular front bar. Multi-Link Rear Suspension Civic Si Exclusive Suspension Tuning To achieve its elevated handling performance, the Civic Si has the following suspension tuning compared to the 2012 Civic Coupe:
2012 Civic Si Coupe chassis Motion Adaptive Electric Power Steering (EPS) When VSA is activated, EPS quickly applies torque to help the driver steer in the ideal direction to stop the vehicle from swerving. When activated, the system provides unique steering wheel feedback to alert the driver, thus increasing confidence and control. Using vehicle speed and steering angle data, Motion Adaptive EPS works with Vehicle Stability Assist (VSA®) and Electric Power Steering to detect instability during slippery road conditions (in cornering and under braking) and automatically initiates steering inputs aimed at prompting the driver to steer in the correct direction. This new technology supports the driver's action in operating the vehicle more safely and comfortably. Noted are three examples of how Motion-Adaptive Electric Steering (EPS) functions in conjunction with VSA® : Stabilizes Braking - Corrects the driver’s steering input to reduce vehicle instability when the vehicle is braking hard on road surfaces with different friction coefficients (such as pavement that is partially covered with dirt or snow) Mitigates Understeer - Prompts the driver to not turn the steering too far in an effort to mitigate understeer Mitigates Oversteer - Corrects the steering inputs to mitigate oversteer and help the driver trace the intended path of travel through the curve Electric Power Steering (EPS) The EPS system consists of a rack-and-pinion steering gear with an electric motor installed concentrically around the steering rack. To control the level of assist that the Powertrain Control Module receives, signals from a speed sensor (coupled with a steering sensor for torque and rotation) calculates the optimal amount of steering assist and then sends a signal to the electric motor. When compared to the operation of a conventional hydraulic pump power steering system, the more simple and lightweight EPS system increases efficiency because it does not draw a continuous amount of power directly from the engine. Other advantages of electric power-assisted steering include its simplicity and compactness (no hydraulic system is needed to power it) and its lower power consumption, which helps improve fuel economy. The steering ratio on all Civic models is 16.1:1, resulting in 3.1 turns lock-to-lock. All 2012 Civic models have a tilt and telescope steering wheel. Disc Brakes with Anti-lock Braking System (ABS) The 4-channel ABS independently modulates braking power at each wheel to help the driver retain steering control during heavy braking. EBD automatically optimizes braking force between the front and rear wheels, helping to ensure that the Civic stops in the shortest distance possible regardless of the number of passengers or amount of cargo that it is carrying With EBD, Civic drivers will notice improved pedal feel and reduced brake fade under strenuous driving conditions. Brake Assist recognizes emergency braking situations and almost instantly applies full braking force when appropriate. (Please see Safety section for more information). Civic DX, LX, Hybrid and HF models are equipped with 10.3-inch diameter ventilated front brake rotors (0.8-inch rotor thickness) clamped by single-piston brake calipers. At the rear are 7.8-inch diameter drum brakes. With Civic EX, EX-L and Si models, the rear drum brakes are replaced with disk brakes that incorporate 10.2-inch diameter solid rotors (0.4-inch rotor thickness) paired with single-piston brake calipers. Civic Si models are equipped with 11.8-inch rotors (1.0-inch thickness) paired with single-piston brake calipers. Additionally, the Civic Hybrid’s hydraulic brake booster cooperates electronically with the Engine ECU to provide optimum regenerative braking. Wheels and Tires The use of larger wheels and tires contribute to the Civic Si’s enhanced handling. The Civic Si comes with 17x7 inch aluminum wheels with P215/45R17 all-season tires. With the Civic Si Coupe and Sedan, available is a summer-only performance tire package. The Civic Hybrid and Civic HF features P195/65R15 low rolling resistance tires mounted on lightweight and aerodynamic 15x6-inch alloy wheels.

Overview Honda has long been known for its world-class engine technology and a continuous advancement of innovation and improvement. At the core of Honda's powertrain engineering is the ongoing pursuit of greater performance, enhanced fuel economy and low emissions. The 2012 Civic embodies this effort with a range of gasoline, hybrid and Compressed Natural Gas (CNG) powertrains that offer unique solutions for different buyers. For performance, the Civic's range of powertrains is led by the Civic Si with a new 201-horsepower, 2.4-liter i-VTEC® four cylinder engine matched with a close-ratio 6-speed manual transmission. For maximum fuel economy, the Civic Hybrid is powered by a 110-horsepower, ultra-efficient 1.5-liter i-VTEC four cylinder engine with Integrated Motor Assist (IMA) and a Continuously Variable Transmission (CVT). Designed as an all-around performer to meet the needs of a broad audience, the innovative 140-horsepower, 1.8-liter i-VTEC four cylinder engine is standard in the Civic Sedan, Civic Coupe and Civic HF. The Civic Sedan and Civic Coupe offer a choice of a standard 5-speed manual transmission (standard on sedan DX and LX and Standard on coupe DX, LX, EX ) or an available 5-speed automatic transmission, while the Civic HF has a standard automatic transmission. A variant of the same 1.8-liter four cylinder engine develops 110 horsepower in the Compressed Natural Gas (CNG)-powered Civic Natural Gas, which comes with a standard 5-speed automatic transmission.

Civic Si Powertrain Available in either a coupe or sedan, the 2012 Civic Si is powered by a new 2.4-liter inline four cylinder engine that is the largest and most powerful in Civic history in America. A range of innovative features help this new powerplant deliver a cutting-edge combination of performance, fuel efficiency, and low emissions. With the i-VTEC "intelligent" valve-control system and new friction-reducing technologies and the Civic Si has prioritized exhilarating acceleration, improved fuel economy and low exhaust emissions.The Civic Si engine is a dual overhead cam (DOHC) all-aluminum, 2.4-liter inline 4-cylinder design that uses 16 valves, the i-VTEC system and a specially tuned high-volume intake manifold. The Civic Si produces 201 horsepower, up 4 horsepower versus the 2.0-liter engine it replaces. A key difference is the 0.4-liter larger displacement, which helps put the peak power at a more accessible 7000 rpm instead of the previous engine's 7800 rpm peak. The increased displacement contributes to a substantial 22-percent increase in peak torque, reaching 170 lb-ft. at just 4400 rpm, which is 1700 rpm less than the previous engine's 139 lb-ft. at 6100 rpm. Despite an increase in engine size, horsepower and torque, the 2012 Civic Si's engine delivers an estimated EPA 1 mpg increase in city driving (22 mpg) and a 2 mpg increase in highway driving (31 mpg) compared to the 2011 Civic Si. In keeping with Honda's proven commitment to the environment, the Civic Si engine meets strict Ultra-Low Emission Vehicle (ULEV-2) tailpipe emissions standards. The Civic Si is available exclusively with a 6-speed manual transmission fitted with a short-throw shifter assembly. Designed to be compact and lightweight, the 6-speed has also been engineered to provide a short, firm and direct shift action. The Civic Si also includes a clutch system with a torsion mechanism that enhances refinement in terms of engagement and feel. Civic Si Powertrain Summary Engine

Civic Si: Engine Block/Crankshaft and Low Friction Engine Design The Civic Si engine features a compact aluminum cylinder block with cast-in iron liners— a design known for its light weight, high rigidity, and excellent durability. The block has a one-piece aluminum crankshaft carrier, which has ferrous-carbon inserts in the bearing caps for additional strength. Further adding strength is a stiff, cast-aluminum oil pan. The crankshaft is a highly rigid, forged-steel design that uses a micro-polished surface finish for reduced friction and increased durability. In addition, the engine uses high-strength connecting rods and crankshaft as well as high-compression cast-aluminum pistons. Compared to the smaller engine in the previous generation, the new Civic Si engine has a 1mm increase in bore (now 87mm) and a 13mm increase in stroke (now 99mm). Through the application of new piston coatings and cylinder sleeve plateau honing, operating friction is reduced. Plateau honing lowers the friction level between the pistons and the cylinders by creating an ultra smooth surface. Plateau honing is a 2-stage machining process that uses two grinding processes instead of the more conventional single honing process. This also enhances the long-term wear characteristics of the engine. Ion-plated piston rings and low viscosity oil (0W-20) are also used to reduce friction. Civic Si: i-VTEC Overview Civic Si: i-VTEC Valvetrain The VTEC component of the i-VTEC system adjusts the lift and duration of intake valve opening to help the engine produce both abundant low-rpm torque and excellent high-rpm power. At low rpm, VTEC provides valve timing and lift for optimum cylinder filling. In addition, the timing of the intake valves is staggered and their lift asymmetric— creating a swirl effect within the combustion chambers. The result is increased burn speed with improved combustion stability. As engine rpm builds, VTEC transitions to a high-lift, long-duration cam profile for improved high-rpm engine output. The Civic Si uses a high-performance version of VTEC that varies the lift and duration of the intake valves for maximum power output. At lower rpm, the valves follow low lift, short duration camshaft profiles to help boost low-end torque. Above 5,000 rpm, the intake valves are operated by high-lift, long-duration cam profiles, for maximum high-rpm horsepower. When combined with VTC, both cam profiles help the Civic
Si engine produce a remarkably broad and smooth power band with both excellent torque and horsepower. Civic Si: VTC (Variable Timing Control) During typical operation, the intake camshaft timing is almost fully retarded at idle to help provide more stable idling while reducing exhaust emissions (NOx). As rpm increases, the intake camshaft is advanced, opening the intake valves sooner and providing additional valve overlap. This results in increased fuel economy (by reducing pumping losses) and a further reduction in exhaust emissions (by creating a large, internal exhaust gas re-circulation effect). Also, to generate additional power throughout the rpm range, the intake camshaft is continuously varying the amount of advance or retard, instantly adjusting to provide additional power as required by the driver. Civic Si: High-Flow Induction System The induction system is designed for high flow as well as to create an aggressive sound. The lightweight composite intake manifold has fixed-length intake runners that are tuned in length, diameter and shape to provide an optimal blend of low-rpm torque and high-rpm response. Civic Si: Drive-by-Wire Throttle Control An electronic Drive-by-Wire throttle control system helps enhance the driving character of the Civic Si. With smart electronics connecting the throttle pedal to the throttle body attached to the inlet of the intake manifold, the engine response can be optimized to suit the driving conditions and to better match the driver's expectations. The Civic Si uses a DC motor to control the throttle body opening position in the intake tract. To establish the current driving conditions, the system monitors items such as pedal position, throttle position, vehicle speed, engine speed and engine vacuum. This information is then used to define the throttle control sensitivity. Civic Si: Programmed Fuel Injection (PGM-FI) Civic Si: Direct Ignition System and Detonation Knock Control A strong ignition spark is critical to produce strong power and reduce emissions. The 2.4L I-4 features a direct ignition system that uses individual coil units for each cylinder that are positioned directly above each spark plug. The Powertrain Control Module (PCM) continually monitors several engine parameters to determine optimum spark timing based on specific driving conditions. Additionally, a block-mounted acoustic detonation (knock) sensor sends information per each rotation, so that the engine can analyze each frequency with high precision. This signal is sent to the PCM, which then controls ignition timing as needed to help prevent damage. Civic Si: Exhaust System The Civic Si features an exhaust manifold design that is integrated directly into the cylinder head casting. This unique design allows the high-density catalytic converter to be positioned very close to the cylinders for faster converter light-off after a cold engine start for reduced hydrocarbons and NOx. Emissions performance is further improved thanks to the engine's design, which positions the exhaust manifold on the rear of the engine—which shortens the distance that the exhaust gases must travel to the secondary catalytic converter, positioned downstream under the passenger compartment floor. To help boost engine torque, a high-flow, low backpressure exhaust system is standard on the Civic Si. Large-diameter stainless-steel tubing used throughout the exhaust system increase flow; beyond the under-floor catalytic converter, the exhaust system passes through a pre-chamber (located under the second-row floorboards), and then to a free-flow silencer fitted with a chrome exhaust finisher. Civic Si: Noise, Vibration and Harshness (NVH) Control In addition to its outstanding power and response, the Civic Si engine has been designed for class-leading smoothness and refinement. The 2.4-liter, 4-cylinder engine employs such NVH-reducing features as a chain-driven balancer unit in the oil pan; ferrous-carbon inserts in the main bearing caps for added rigidity; a one-piece crankshaft carrier; a silent chain cam drive; and a stiff, cast-aluminum oil pan. A torque-rod damper system attached to the subframe helps reduce engine rocking and isolates powertrain NVH from the passenger compartment. The torque-rod engine mount system consists of upper and lower torque rods attached to the engine mount and a front beam stopper. Civic Si: Maintenance Minder System The Civic Si features as standard equipment a Maintenance Minder™ system that automatically monitors the vehicle's operating condition. The driver is alerted via a message on the intelligent Multi-Information Display (i-MID) when maintenance is required. The system helps eliminate unnecessary service stops, while ensuring that the vehicle is properly maintained. The Maintenance Minder™ system monitors operating conditions such as coolant and oil along with engine speed, and then determines the proper service intervals. The Multi-Information Display shows the remaining percentage of engine oil life, and a percentage-based countdown to the next service is displayed when the car is within 15 percent of the end of the service interval. The type of service required is shown in an alphanumeric code, and if a service is missed, the i-MID indicates its urgency by showing past-due mileage. The system can be reset manually by the owner, and monitors all normal service parts and systems, including oil and filter, air-cleaner, tire rotation, coolant, spark plugs, brake pads and more. Maintenance alerts are presented on the instrument cluster when the ignition is first turned on, and not while driving. Civic Si: 6-Speed Manual Transmission To provide driving enthusiasts with exceptional control and feel, the high-performance Civic Si is available exclusively with a short-throw, close-ratio 6-speed manual transmission. Compared to a 5-speed transmission, the 6-speed gearbox allows closer gear ratio spacing. Such tighter gear spacing enables the engine to operate closer to its power peak during acceleration for better performance. The compact transmission case is cast of aluminum to reduce weight. Additionally, the highly rigid casting helps damp out noise and vibration. Multi-cone synchronizers on First through Fourth gears reduce and smooth shifting effort. With the substantially improved torque output of the new Si engine, the Second through Sixth gear ratios have been made slightly higher (lower numerically). This allows the larger displacement engine to operate comfortably in the heart of its powerband under acceleration and to reduce highway cruising rpm. The close-ratio 6-speed manual transmission teams with a lightweight, high-capacity clutch, and a specially designed clutch pedal assembly that delivers low-effort actuation and has a broad engagement band for greater control and smoother launches. Civic Si: Limited-Slip Front Differential Powerful performance cars with conventional "open" differentials can suffer from excessive wheelspin, particularly from the inner drive wheel when cornering. The Civic Si's helical-type limited-slip differential (LSD) helps insure that excessive wheelspin doesn't happen, by putting more of the engine's power effectively to the pavement.Under power, the limited-slip differential works to equalize the speed of the two drive wheels. The system never locks the speed of the two drive wheels together as would a locking differential, but instead allows different wheel speeds to accommodate the longer distance the outer wheel must travel when cornering. The LSD allows the Si to accelerate harder on surfaces with uneven traction, to generate reduced wheelspin when exiting corners, and to enhance the vehicle's responsiveness to throttle inputs in corners.The term "helical" describes the way the differential's gear teeth are cut— which is at an angle to the gear's shaft. Helical gears are quieter in operation and can transmit greater torque than straight-cut (or spur) gears. Civic Hybrid Powertrain The fifth-generation Honda IMA system in the Civic Hybrid now consists of a larger 1.5-liter i-VTEC 4-cylinder engine connected to a larger, more powerful electric motor and a Continuously Variable Transmission (CVT) to optimize the rpm of the engine and motor combination. The engine incorporates new friction-reducing technologies, and a new lithium-ion (Li-Ion) battery pack developed specially for the Civic Hybrid is used to capture and store electricity for the electric motor. The system uses a gasoline engine as the primary source of power and an electric motor provides additional power and electricity regeneration capability. During acceleration, the engine or the engine and electric motor propel the vehicle. During cruising, the gasoline engine and/or the electric motor can propel the vehicle. During braking, the gasoline engine deactivates and the electric motor acts as generator to replenish the battery pack. At a stop, the engine can enter an idle-stop mode to save fuel and reduce emissions, and the engine remains turned off until the brake pedal is released. Compared to the previous Civic Hybrid, the fifth-generation Honda IMA powertrain provides stronger starting and overtaking acceleration compared to its predecessor, while its EPA-estimated fuel economy of 44 mpg city and 44 mpg highway offers an improvement of 4 mpg in the city and 1 mpg on the highway. The gasoline engine and electric motor combine to produce maximum output of 110 horsepower @ 5500 rpm and 127 lb-ft. of torque @ 1000-3500 rpm. Compared to the previous generation Civic Hybrid, the new Hybrid has the same peak horsepower, but achieves it at 500 fewer rpm. The new Hybrid has gained 4 lb-ft of torque, and it is spread over a wide rpm range, from 1000 to 3500 rpm. The previous Civic Hybrid reached its peak torque between 1000 and 2500 rpm. The upgraded, lighter electric motor is designed to provide up to 23 horsepower, and is powered by a new lithium-ion battery system that is more powerful, lighter and more compact than the Nickel-Metal-Hydride (NiMH) battery it replaces. The Powertrain Control Unit (PCU) has been newly developed to maximize the lithium-ion battery's power and minimize energy loss. Due to the IMA system's greater power and the battery's 35-percent increase in efficiency, the Civic Hybrid can operate in EV mode a greater distance than in the past.

Civic Hybrid: Engine Block, Pistons and Connecting Rods The aluminum engine block and its internal components create a lightweight package with extremely low friction qualities. To save weight, the block incorporates a thin-sleeve cylinder bore construction. Friction reducing measures include plateau honing, low friction pistons, low-tensile force piston rings and offset cylinder bores to help reduce piston lateral loads. Plateau honing lowers the friction level between the pistons and the cylinders by creating an ultra smooth surface. Plateau honing is a 2-stage machining process that uses two grinding processes instead of the more conventional single honing process. This also enhances the long-term wear characteristics of the engine. The outer skirts of lightweight aluminum pistons now feature a molybdenum coating applied in a unique dot-pattern application. The result is reduced overall friction as the pistons move within the cylinder bores. Civic Hybrid: Cooling Control Spacer (CCS) Civic Hybrid Cylinder Head: 2-Stage i-VTEC with Variable Cylinder Management (VCM) The Civic Hybrid's single overhead camshaft (SOHC) cylinder head uses a compact chain drive system and a compact, low-friction VTEC valvetrain system. It uses a common rocker shaft for both the intake and exhaust rocker arms; placing all the rocker arms on one shaft eliminates the need for a second rocker-arm shaft, so the valve mechanism can be lighter and more compact. To reduce friction, the rocker arms feature tips with roller followers. The compact valvetrain allows for a desirable narrow angle (30-degrees) between the intake and exhaust valves, which allows for compact combustion chambers. The intake ports create a swirl effect in the cylinder chambers that promotes a well-balanced and even air/fuel mixture as it enters the engine. This optimizes the air/fuel mixture for cleaner, more efficient combustion. The VCM allows the regenerative braking system to reclaim as much energy as possible during deceleration, while also allowing the electric motor to propel the vehicle in certain steady-state cruising situations. Since the electric motor, which also acts as an electric generator, is attached directly to the crankshaft of the engine, the engine needs to provide as little resistance as possible during deceleration to allow the generator to produce the maximum level of electricity to charge the batteries. In a traditional engine, the pumping action of the cylinders provides a moderate amount of resistance, or "engine braking," during deceleration. VCM virtually eliminates that effect, allowing the electric generator to recapture energy and provide a convention "engine braking" feel for the driver. "Intelligent" Dual & Sequential Ignition with Two Spark Plugs Per Cylinder When the air/fuel mixture enters the combustion chamber, the first plug located near the intake port ignites. Shortly thereafter, the second plug located near the port ignites, accelerating the combustion process by forcing the flame to propagate more rapidly. The spark plugs can also ignite simultaneously under certain circumstances. This process results in more complete combustion compared to a single sparkplug system. Civic Hybrid: Drive-by-Wire Throttle with Engine Speed (CVT) and Motor Control An electronic Drive-by-Wire throttle system helps enhance the driving character of the Civic Hybrid. Smart electronics measure accelerator pedal position, then adjust the throttle-body butterfly valve for the intake manifold, the gear ratio in the CVT, and the operation of the IMA to best suit the driving conditions. To determine the current driving conditions, the system monitors pedal position, throttle position, vehicle speed, engine speed, calculated road slope and engine vacuum. With this information, the Drive-by-Wire throttle system controls motor and engine power to maximize the output of the new Lithium-Ion battery. Civic Hybrid: ECON Mode When in Eco Mode, the maximum threshold for maintaining a set cabin temperature (when the A/C is on) is slightly increased when conditions warrant in order to minimize the activation of the compressors and contribute to enhanced fuel efficiency. Civic Hybrid: Hybrid Dual-Scroll Air Conditioning Compressor For 2012, an enlarged dual-scroll hybrid air conditioning system reduces the load on the gasoline engine by using a combination of engine power and an internal electric motor to drive two air conditioning compressors. These compressors can act independently or together as dictated by the cooling needs of the Civic Hybrid's automatic climate control system. Civic Hybrid: IMA System Civic Hybrid: IMA Electric
Motor In addition to providing supplemental power, the IMA motor acts as a generator during deceleration and braking to recapture kinetic energy and recharge the IMA's battery pack during regenerative braking. For this fifth generation of IMA motor, an 8-pole design (instead of the previous 6-pole design) reduces heat. The new motor also operates in a lower voltage range (108-172V) compared to the previous motor (132-211V). Civic
Hybrid: IMA Intelligent Power Unit (IPU) The battery pack stores electricity in a bank of lithium-ion cells. This bank of 40 individual 3.6-volt batteries stores up to 144 volts of electrical energy for the IMA motor. The new lithium-ion battery technology has approximately twice the energy density and about four times the output density of the previous nickel-metal-hydride batteries. Output is increased by 33 percent, volume is reduced by 36 percent, weight drops by 29 percent and the work capacity of the charging and discharging rates is approximately 3 times higher. The Integrated Cooling Unit, mounted directly on the battery pack's outer box, controls the heat generated by the constant flow of electricity to and from the battery pack. Interior cabin air enters the Integrated Cooling Unit via a small vent placed on the left outboard seat bolster and is continually flowed over the battery pack and re-circulated. Civic Hybrid: Cooperative Regenerative Brake System Less reliance on the traditional braking system and reduced engine pumping losses translate into greater electrical regeneration and improved fuel efficiency due to the introduction of VCM system in the new Civic Hybrid engine.
The Civic Hybrid's regenerative braking system intelligently apportions braking power between the hydraulic brakes and the electric motor to extract even more electricity from the vehicle's kinetic energy. During braking, a braking pressure sensor sends a signal to the Intelligent Power Unit (IPU), which maximizes the level of regenerative braking. At the same time, the CVT alters the gear ratio as needed to adjust the rpm of the engine and electric motor to achieve the maximum efficiency for
energy regeneration. Civic Hybrid: Continuously Variable Transmission The Civic Hybrid's CVT offers smooth and predictable gear ratio transitions and excellent low-end acceleration matched with low-rpm cruising. To improve fuel economy with the new, larger engine, the Civic Hybrid's CVT now incorporates additional pressure and temperature sensors to allow more accurate control over the transmission's operation. The transmission has also been upgraded to accommodate the greater torque of the new IMA system. By helping the engine and IMA motor stay in their most efficient operating range, the CVT provides a fuel efficiency benefit superior to that of a conventional automatic transmission with fixed ratio gears, and it allows for greater efficiency during regenerative braking by smoothing deceleration. Civic Sedan, Coupe, HF and Natural Gas Powertrain The Civic Sedan, Coupe, HF and Natural Gas benefit from an updated and refined version of the 1.8-liter engine that powered the previous generation Civic. While peak horsepower and torque figures of the gasoline versions carryover, the new engine has extensive changes that reduce friction, upgrade its emissions performance and increase its fuel economy. For 2012, all Civic Sedan and Civic Coupe models, plus the HF (High Fuel Economy) and Natural Gas (Compressed Natural Gas) sedans are powered by a Single Overhead Cam (SOHC) 1.8-liter inline 4-cylinder design with 16 valves, i-VTEC, and a dual-stage intake manifold. In the Sedan, Coupe and HF, the engine produces 140 horsepower at 6500 rpm, 128 lb-ft. of torque at 4300 rpm and has a ULEV-2 emissions rating. All Civic DX, LX, EX and HF models with automatic transmission are PZEV-rated in states that adhere to California Air Resources Board (CARB) emissions standards. In the Civic Sedan and Coupe, the 1.8-liter engine has an EPA-estimated city/highway fuel economy rating of 28/39 miles per gallon when equipped with automatic transmission.This same powertrain in the Civic HF achieves higher EPA city/highway fuel economy of 29/41 miles per gallon with the standard 5-speed automatic transmission, thanks to the HF model's reductions in aerodynamic drag and rolling resistance. See the Body and Chassis section for more info on the Civic HF. In the Civic Natural Gas, which is powered by Compressed Natural Gas (CNG), the engine develops 110 horsepower and 106 lb-ft of torque. Though its targeted peak figures are slightly lower than those of the previous generation (113 horsepower and 109 lb-ft of torque), torque output below 4000 rpm has been increased for greater drivability. The Natural Gas has a targeted EPA-estimated city/highway fuel economy of 27/38 miles per gallon and is equipped with an automatic transmission as standard equipment.

Civic: High Rigidity Aluminum Block and Low Friction Engine Design Compact, rigid, lightweight and low friction describes the end result of engine technology that helps to enable the Civic to achieve high power and high fuel economy. A narrow width cam chain, a chain case with a built-in oil pump and ferrous spin-cast cylinder sleeves are used to make the engine unusually compact, allowing for excellent packaging efficiency. To make the engine highly rigid, extensive analysis was used to create reinforced areas in the aluminum block construction. Furthermore, a lightweight and very stiff steel crankshaft is used with a high balance ratio that also benefits from a lower block design with extremely high crank support rigidity. At the very bottom of the engine, an aluminum oil pan with integrated stiffeners further adds to rigidity. The high rigidity block design helps reduce noise output and friction. The Civic's 4-cylinder engine now makes use of new friction reducing technologies designed to improve engine efficiency. The outer skirts of lightweight aluminum pistons now feature a molybdenum coating applied in a unique dot-pattern application. The result is reduced overall friction as the pistons move within the cylinder bores. A new plateau honing technique lowers the friction level between the pistons and the cylinders by creating an ultra smooth surface. Plateau honing is a 2-stage machining process that uses two grinding processes instead of the more conventional single honing process. This also enhances the long-term wear characteristics of the engine. Ion-plated piston rings and low viscosity oil (0W-20) are also used to reduce friction. Civic: Cracked Connecting Rods High-strength crack-separated connecting rods are used to minimize weight and size, while also increasing connecting rod rigidity and long-term durability. A "cracked" connection means that the rod and cap are forged as a single unit during the manufacturing process, and then are cracked apart to create a custom fit between the two matching surfaces. This unique design allows for the elimination of connecting rod bolt pins, since the connecting rod bolts can be precision machined to fit the cap to the rod. The end result is a connecting rod that is 13 percent lighter and has a 20 percent smaller cross section, resulting in less rotating mass inside the engine and less space occupied by the connecting rod. Civic: i-VTEC Valve Control System To achieve strong performance and excellent fuel economy, the Civic's 1.8-liter engine uses a variation of the innovative i-VTEC system. Valve timing specs have been revised for 2012, and this variation of i-VTEC includes single intake valve operation. At low engine speeds, just one intake valve in each cylinder operates, while the second intake valve remains closed. Single intake valve operation is a significant factor in the engine's excellent emissions performance during cold start-up on PZEV-rated models. At high engine speeds, the i-VTEC system locks together both sides of the rocker arm to allow both intake valves to open at the same time. The Civic's i-VTEC system is able to switch valve timing duration using a hydraulic actuator. Torque output has been optimized in the most frequently used 2,000 to 4,000 rpm engine speed range. To this end, the switchover from the low-speed timing to the high-speed valve timing is set between 1,200 rpm and 3,500 rpm depending on engine load. Furthermore, a shutter valve operating the variable intake switches tract length from long to short at approximately 5,000 rpm to best match the more aggressive high-speed valve timing. This Civic's i-VTEC valve timing reacts to driving conditions related to throttle opening, vehicle speed, engine rpm and gear selection. A sophisticated Drive-by-Wire throttle control system, air flow meter, knock sensor and dual-stage air intake allow the Powertrain Control Module (PCM) to create seamless transitions between the two modes of i-VTEC operation. In theory, intake ports should be designed as straight as possible to promote more complete filling of the cylinders. However, with the objective of promoting the mixing of fuel with the incoming air, Honda has devised a curved intake port for the Civic. This strategic curve not only promotes improved air-fuel mixture, but it is also designed to better concentrate the mixture around the spark plug. This allows for an even more efficient combustion process and further increased fuel efficiency. Civic: Composite Plastic Dual-Stage Intake Manifold A composite plastic dual-stage intake manifold utilizes two intake runners for each cylinder— with one runner longer than the other. Below 5,000 rpm, only the longer of the two runners delivers air to the cylinder—taking advantage of an inertia effect of the long intake path. Above 5,000 rpm, however, a shutter valve in the bore of the short runner opens to allow the passage of additional air to the cylinder. This has the effect of boosting midrange and high-rpm power by utilizing the inertia effect at both low and high rpm. Civic: Drive-by-Wire Throttle Control An electronic Drive-by-Wire throttle system helps enhance the driving character of the Civic. With smart electronics connecting the throttle pedal to the throttle butterfly valve in the intake system, the engine response can be optimized to suit the driving conditions and to better match the driver's expectations. Combined with the dual-stage intake manifold, the Drive-by-Wire throttle system is an important component to the i-VTEC system that makes switching between the engine's low pumping loss mode and the high performance mode seamless to the driver. By eliminating the direct throttle cable connection to the engine, the ratio between pedal movement and throttle butterfly movement can be continuously optimized. This adjustable "gain" between throttle and engine is a significant benefit to drivability. A highly responsive DC motor moves the throttle butterfly position in the intake system to change actual throttle position. To establish the current driving conditions, the system monitors pedal position, throttle valve opening position, vehicle speed, engine speed, and engine vacuum. This information is then used to define the throttle control sensitivity. The throttle system also works to enhance the available 5-speed automatic transmission's ability to make shifts faster and smoother. By coordinating the throttle opening with the transmission's shifting functions, engine power can be precisely tailored to the needs of the transmission at every point during the shifting process. That means less shift shock and delay, no matter the driving situation. Civic: ECON Mode All Civic models (except Si models) have as standard a driver-selectable "ECON" driving mode that alters the Drive-by-Wire throttle system response curve in the range from about 25 percent of pedal movement to 90 percent. With less gain, the throttle opening in this range increases
more gradually, for better fuel efficiency. ECON mode also alters shift timing (when equipped with automatic transmission), and alters the operation of the air conditioning system (see the Interior section for more information). Civic: Programmed Fuel Injection (PGM-FI) The Civic engine features Programmed Fuel Injection (PGM-FI) that uses an array of sensors to constantly monitor a number of critical operating variables, including throttle position, intake air temperature, water temperature, ambient air pressure (altitude), air flow, along with the position of the crankshaft and camshafts. A new high-performance air/fuel sensor contributes to the engine's enhanced emission performance. Special multi-hole fuel injectors mounted in the lower intake manifold spray directly toward the intake ports. The multi-hole injector design means that fuel droplet size is reduced for better fuel atomization, resulting in improved cold weather start-up, better fuel efficiency and higher horsepower. Civic: Direct Ignition System and Detonation Knock Control A strong ignition spark is critical to improve power and reduce emissions. The 1.8L I-4 features a direct ignition system that uses individual coil units positioned directly above each spark plug. The Powertrain Control Module (PCM) continually monitors several engine parameters to determine optimum spark timing based on specific driving conditions. Additionally, a block-mounted acoustic detonation (knock) sensor sends information per each rotation, so that the engine can analyze each frequency with high precision. This signal is sent to the PCM, which then controls ignition timing as needed to help prevent damage. Civic: Exhaust System The Civic is equipped with a stainless-steel, low heat-mass exhaust system integrated into the cylinder head that eliminates the need for a separate exhaust manifold, helping contribute to the engine's compact design and light weight. The system employs a new high-density low precious metal catalytic converter for improved light-off performance along with reduced hydrocarbons and NOx. For improved emissions performance, the catalytic converter bolts directly to the cylinder head, resulting in faster light-off and more complete conversion of the exhaust gases. Civic: Maintenance Minder and Tune-Up Intervals The Civic's engine tune-up schedule is calculated by the Maintenance Minder system. The Maintenance Minder system automatically indicates when to have standard service performed based on actual driving conditions (tracked by the PCM) and minimizes the guesswork related to whether the vehicle is being used in standard or severe use conditions for maintenance interval purposes. The display indicates when to change the oil, air cleaner, transmission fluid, spark plugs or coolant, as well as when to rotate the tires. Under normal usage, a tune-up is not required until approximately 100,000 miles (only routine inspections and fluid changes are required up to this point). Credit for this longevity goes to long-wearing double-tipped spark plugs, a long-life timing chain, and careful engineering of the precisely manufactured SOHC valvetrain— which reliably maintains proper valve tappet clearances until the first tune-up. Civic Natural Gas Engine The Civic Natural Gas, previously known as Civic GX, is powered by a variant of the same 1.8-liter engine found in all Civic models, with the exception of the Civic Hybrid and Civic Si. First introduced in 1998, the Civic GX has been marketed primarily to fleet customers nationwide, but with the arrival of the 2012 Civic Natural Gas, it is now being made available at select dealers across the country. The Civic Natural Gas operates on compressed natural gas and has as standard a 5-speed automatic transmission. The Natural Gas has a Honda-targeted EPA-estimated city/highway fuel economy of 27/38 miles per gallon (gasoline equivalent). Compared to the previous generation, city fuel economy is improved by 12.5 percent, and highway fuel economy is increased by 5.6 percent. To allow the engine to operate exclusively on natural gas, it incorporates a range of unique features. The compression ratio is increased to 12.7:1 (compared to 10:6 in regular gasoline-powered engines) to improve performance with the gaseous fuel. Since CNG fuel is non-lubricating, the engine has exclusive intake and exhaust valves and different valve seats to reduce wear. Special, stronger connecting rods are used to handle the extra load generated by the higher compression ratio. To control the flow of CNG into the engine, a single-stage pressure regulator is located on the right side of the engine compartment. Special fuel injectors deliver precisely metered amounts of CNG into each cylinder's intake tract. Civic Natural Gas: Emissions The Civic Natural Gas GX is certified to the Federal Tier II, Bin 2 emission level, and is also certified as a Super Ultra Low Emission Vehicle (SULEV) by the California Air Resources Board (CARB). It complies with AT PZEV, (Advanced Technology, Partial Zero Emission Vehicle) criterion established by CARB, allowing the Civic Natural Gas credits toward the California Zero Emission Vehicle mandate. It is recognized as a PZEV by meeting SULEV standards and maintaining its emissions durability for at least 150,000 miles or 15 years. SULEV requirements are the most rigorous in the world, calling for a reduction in hydrocarbon emissions of 96 percent from federal Tier-1 passenger car levels, and an 86 percent reduction compared to the California Low Emission Vehicle (LEV) standard. Since it operates exclusively on natural gas with no provision for gasoline, the Federal EPA categorizes the Civic Natural Gas as an ILEV (Inherently Low Emission Vehicle) recognizing its sealed fuel system emits zero evaporative emissions. Due to its efficiency and emissions performance, in many states the Civic Natural Gas has been granted carpool lane access— a major benefit for solo commuters. Civic Natural Gas: Fuel Tank The Civic Natural Gas has a cylindrical fuel tank for compressed natural gas located behind the rear seatback. The composite tank has an aluminum liner and can contain the gasoline-gallon equivalent of approximately 8.0 gallons when pressurized to 3600 p.s.i. Civic: 5-Speed Manual Transmission The 5-speed manual transmission is a lightweight and compact unit that minimizes power-robbing rotating mass and has a rotating selector link for quick and direct gear changes. Additional features include a low-friction design with single cone synchronizers and high capacity bearings throughout. From a performance standpoint, the manual transmission has a high torque capacity and a short, firm and direct shift feel. Civic: 5-Speed Automatic Transmission The Civic Sedan and Civic Coupe are available with an electronically controlled 5-speed automatic transmission. The computer-controlled transmission provides amazingly smooth shifts, and has gear ratios that are closely matched to the output of the engine help extract maximum performance. For 2012, the transmission incorporates refinements that enhance fuel economy, reduce noise and save weight. It now incorporates an automatic transmission fluid (ATF) warmer/cooler that uses the engine coolant to alter the temperature of the ATF. This helps reduce ATF viscosity more quickly when starting from cold with a consequent reduction in friction and related reduction in fuel consumption. Conversely, when transmission oil temperature rises above engine coolant temperature, the system helps reduce the temperature of the transmission. The 5-speed automatic transmission uses a wide variety of technologies to help provide smooth shifting as well as minimal friction for enhanced efficiency. These technologies include a low-friction clutch and a special super-thin torque converter, now with greater capacity. The thin torque converter results in a compact transmission unit. Other space-saving measures include a double-row idle gear and a tightly packaged second-gear clutch. To improve powertrain smoothness and reduce gear "hunting" on steep grades, the 5-speed automatic transmission is also equipped as standard with a Grade Logic Control system. Using sensors that monitor throttle position, vehicle speed, and acceleration/deceleration and then comparing these inputs with a map stored in the transmission computer, the system is able to determine when the vehicle is on an incline and adjust the shift schedule for improved climbing power or downhill engine braking. To improve fuel economy while maintaining a high level of drivability, the 5-speed automatic transmission includes an active lock-up torque converter. With the precise control afforded by a linear solenoid, the system expands the speed and throttle setting range in which lock-up can be automatically engaged. *Fuel economy values determined from manufacturer test results.

Overview Creative and expressive, roomy and practical – the 2012 Civic's interior is as impressive as the body design, while featuring a bold and advanced instrument layout that's unlike anything in the class. The new Civic interior builds on the already sophisticated design of the current generation Civic by adopting a “smart interface” approach. With this approach, the interior is divided into different areas, with the key instrument displays (such as vehicle speed) located exceptionally high up and above the steering wheel rim, close to the driver's line of sight. Secondary information (such as engine rpm) is located lower in the area, visible through the steering wheel. A third area to the driver's right groups controls that are not essential to driving. Overall, the controls are clear and easy to operate, with a cleanly simple layout and highly intuitive operation. Crisp, smart and fresh, the new Civic's interior is a careful blend of both form and function. All the shapes, textures and colors work together to create a welcoming contemporary environment that is both visually and tactilely rewarding. Everything the driver needs is close at hand and logically placed, but not at the expense of the overall openness of the cabin. The materials and finishes are as carefully selected as the equipment features. Distinct upper and lower areas of the instrument panel have their own unique materials that create visual zones that add beauty and richness. While virtually everything that the driver and passengers come in contact with – from the instrument panel to the switches and controls, to the stitching on the Civic EX-L's perforated leather-wrapped steering wheel – are crafted to be pleasing to the touch, and ideally placed for use. Building on the successful packaging on the previous generation Civic, the 2012 Civic Sedan has gained a small amount of interior passenger volume and made gains in shoulder and hip room. The Civic Coupe returns with an increase in front shoulder room. Interior Summary
Civic Si
Civic Hybrid
Interior Dimensions The Civic Sedan is classified by the Environmental Protection Agency (EPA) as a compact car based on its passenger volume, yet the interior feels larger in part due to its smart packaging and careful attention to details such as knee room, shoulder space and hip room – among many other factors. Compared to the previous generation, the 2012 Civic Sedan passenger volume of 94.7 cubic feet (Civic LX Sedan) increases by 3.7 cubic feet, and gains have also been made in front shoulder room (+2.9 inches) and rear legroom (+1.6 inches). The Civic Coupe has gained 1.2 inches in front shoulder room. Other interior dimensions are within an inch of the previous generation. The Civic Coupe is classified as a Subcompact. Civic Sedan
Civic Coupe
Increased visibility The 2012 Civic's body and glass have been completely redesigned to provide added outward visibility for the driver and passengers. Added side glass area at the bases of thinner A-pillars improves visibility in turns and eases maneuvering and parking. Thinner C-pillars provide a better rearward view with Civic coupe models. Two-Tier Instrument Panel Like its predecessor, the 2012 Civic uses a unique two-tier instrument panel design. Honda research analyzed the eye movements of drivers and prioritized the importance of the Civic's instruments and their placement for quick recognition. Based on this research, a two-tier instrument panel was devised that groups a portion of instrumentation in the conventional location (viewed through the steering wheel), and a separate upper tier that's visible above the steering wheel and close to the driver's line of sight. A digital speedometer, fuel gauge and instant fuel economy gauge are housed in the upper level to be more in-line with the driver's line-of-sight, resulting in shorter eye movements between the most commonly referenced gauges and the road. The top-tier also includes eco-coaching bars (Civic Si excepted) and the new full-color i-MID (Civic DX excepted), which serves as a multi-function display and provides easy access to a range of features, a number of which are customizable. The i-MID serves as the audio system display and also includes the clock, odometer, trip meter, outside temperature (Civic EX and above) and Maintenance Minder displays. The lower level of the instrument panel houses a tachometer, and a variety of warning indicators. On vehicles with an automatic transmission, the gear selector position is also displayed. Instrument panel illumination on all models except the Si uses a blue color scheme with white backlit buttons. The Civic Si's unique, red-backlit instrument panel accentuates the car's sporting ambience. Civic Si: Sequential Rev-limit Indicator For the performance-oriented Civic Si, a new sequential rev-limit indicator is positioned high in the instrument panel, just to the left of the speedometer display where it's close to the driver's line of sight. The sequential rev-limit indicator comprises two main components: an i-VTEC indicator and a redline indicator. The i-VTEC indicator lights up when the VTEC system shifts from the low- to high-rpm cam profiles. The redline indicator is an array of six lights that illuminate sequentially as engine speed rises. The first four lights are orange, and the last two are red. When the second of the two red lights comes on, the engine is producing maximum power. With this sequential presentation, it's easy for the driver to operate the engine in its “sweet spot” while keeping attention on the road during high performance driving. ECO Assist All Civic Sedan and Coupe models (except Civic Si) come with ECO-Assist. Located in the upper instrument panel located on either side of the speedometer, the Civic's ECO-Assist display shows how drive energy is being used and coaches the driver to operate the vehicle more efficiently. The system operates in essentially the same manner as on Insight and CR-Z, with blue and green “coaching” bars that illuminate. A blue color signifies inefficient driving, while green means more efficient driving techniques are being used. The color changes gradually in response to driving technique. ECO Assist can also be turned off, using the customizable settings accessed via the i-MID. When off, the ECO Assist coaching bars remain blue. Intelligent Multi-Information Display (i-MID) Positioned in the upper right portion of the instrument panel, a new “intelligent” Multi-Information Display (i-MID) displays data with color and clarity and an interactive element. This bright, full color 6.5-inch (diagonal) LCD W-QVGA display is easy to see and interpret, and lends the Civic a technologically advanced aspect that's new to this class. The i-MID serves as the audio system display and features on-screen icons and prompts make navigation through a range of screens simple and straightforward. In addition to audio information, the i-MID also displays fuel-economy information, as well as Bluetooth® HandsFreeLink® information and turn-by-turn navigation directions on Civic models equipped with those features. User-support features include customizable settings and a customizable wallpaper display. Recommended wallpaper pixel dimensions are 234x480, 468x960, 702x1440 or 936x1920. The i-MID also displays warnings such as door ajar, SRS, parking brake and TPMS. The intelligent Multi-Information Display (i-MID) is a versatile and handy warning and information readout that tracks and informs the driver of numerous important systems. The i-MID information categories include:
Civic Hybrid: Driver-Feedback System A unique feature of the Civic Hybrid i-MID is a driver-feedback system that monitors driving style and displays how it affects fuel efficiency. It also provides feedback so that adjustments can be made to operate the vehicle more efficiently. When the ignition is switched off, the Eco Scoring system keeps track of the driver's history. So aside from the money owners will save by increasing their mileage along with the satisfaction of helping to lower emissions, they'll also have bragging rights when they talk to other Civic Hybrid drivers. The heart of the system is the Eco Guide and the fuel-economy indicator. The Eco Guide is located in the intelligent Multi-Information Display (i-MID), and the fuel-economy indicator (Eco Assist) is located on either side of the digital speedometer. Together, these displays keep drivers constantly informed about how fuel efficiently they're driving. Also included in the i-MID is a unique hybrid power-flow meter. Civic Si: Power Monitor The Civic Si i-MID includes a Power Monitor screen that displays the engine's power output by percentage. Based on engine torque and rpm, the Power Monitor provides sporting oriented Si drivers with detailed real-time information on engine output. The clear graphic presentation of the engine's output can help drivers fine-tune their performance driving technique. ECON Mode Every 2012 Civic (except for Civic Si) is equipped with an ECON button, a feature that first appeared on the second-generation Insight. This button engages ECON mode, in which several operating characteristics of the vehicle are modified to further enhance fuel efficiency. The Drive-by-Wire throttle system provides more gradual response, and on automatic transmission-equipped models, the shift mapping is reconfigured to provide earlier upshifts. To save additional energy, the climate control's upper five fan speeds (of a total of six) are lowered incrementally and other climate control system characteristics are altered based on the conditions. See the Powertrain section for more information on ECON Mode. Maintenance Minder Display All Civic models have a Maintenance Minder system that tracks service related items based on vehicle usage. The Maintenance Minder system automatically indicates when to have standard service performed based on actual driving conditions (tracked by the ECU) and minimizes the guesswork related to whether the vehicle is being used in standard or severe use conditions for maintenance interval purposes. The display indicates when to change the oil, air cleaner, transmission fluid, spark plugs or coolant, as well as when to rotate the tires. On the Civic DX model, Maintenance Minder information appears in the trip meter display. In all other models it appears in the i-MID display. Steering Wheel The Civic's new 3-spoke steering wheel is a small diameter unit befitting the car's sporty character and accents the vehicle's quick-ratio steering. Civic Si steering wheels are wrapped in perforated leather for an even sportier feel. All models feature manual tilt and telescope steering wheel adjustment in order to better accommodate drivers of various sizes. Civic LX and models above now include audio and i-MID controls on the left side of the steering wheel, with four controls arranged on one ring – rather like the four points on a compass – to simplify the layout and provide for intuitive toggling between functions. All controls are positioned ergonomically where they are easy to reach and operate with minimal distraction for the driver. They also offer a pleasing tactile feel that reduces the need for the driver to confirm operation visually. The controls also indicate operation with visual cues on the i-MID. Civic LX and models above include cruise control buttons on the right side of the steering wheel for set, accelerate, decelerate and cancel. Bluetooth® HandsFreeLink® control buttons are positioned on the lower left side of the steering wheel in all models, with the exception of Civic DX, Civic LX and Civic HF. Interior Materials Every tactile surface, from the interior door handles to the seat controls to the instrument panel, steering wheel, shift lever and electronic controls, latches and lids, are designed to be pleasing to the touch – and easy to operate. Interior panels feature a Honda patented new surface finish that has a rich look and changes in appearance with changing light angle. Cloth upholstery is standard in most Civic models. Civic EX-L and Civic Hybrid with leather both have standard leather seating surfaces. Front Seats For 2012, the front seats of the Civic have been completely redesigned with a more supportive seat construction that features reworked internal springing, structure and padding. Enhanced side bolstering improves comfort when cornering, and reshaped, narrower head restraints and thinner seatbacks help give the interior a roomier feel. Through careful engineering, each front seat is 4.4-pounds lighter than before – evidence of a comprehensive effort to reduce weight throughout the Civic. The Civic Coupe uses deeper side bolsters than the sedan, and the Si further increases lateral support in the both seatback and base. Both front seats can be manually adjusted to recline along with move forward and back. The driver's seat features a manual height adjustment control with two inches total of vertical travel. A ratchet-style lever on the left side of the seat makes adjusting the height easy – just pull up or push down to move the seat in increments. To improve access into the rear seats on the Civic Coupe, the passenger seat has a one-touch seatback release and slide feature. Rear Seats The Civic's rear seats provide roomy comfort and functionality. For greater rear passenger comfort, the interior has a nearly flat rear floor, minimizing the typical tunnel that runs the length of the interior. The flat floor design provides considerably more foot room for middle passengers. To increase storage space, the seats can be folded down to expand the trunk's storage space and accommodate long, bulky items like a snowboard, bicycle or moving boxes. Civic DX, Civic LX and Civic HF models feature a one-piece folding rear seat. Civic EX and Si models feature a 60/40 split folding rear seat for enhanced people/cargo functionality. Trunk-mounted handles release the locks for the seatbacks so they can be folded conveniently. The Civic Hybrid and Civic Natural Gas have fixed rear seatbacks. Interior Storage A redesigned center storage console with a large armrest combines comfort with functionality. Inside the roomy storage compartment, all Civic models with the exception of the Civic DX have a USB port for easy connectivity. An auxiliary input jack is provided at the front of the center console, positioned in a large tray that's ideal for storing mobile devices or other small items. Two large cup holders are positioned in the center console, and each door panel has a built in storage bin and bottle holder. Coupe models have a bottle holder and storage bin integrated into each side of the rear cabin. For the Civic EX, Civic EX-L and the Civic Si Sedans, two more beverage holders are located in the rear seat center armrest. The instrument panel provides additional storage – a spacious traditional glove box, and an open compartment to the left side of the steering wheel. Civic Hybrid: Automatic Climate Control Civic Hybrid is equipped with an automatic climate control system. The driver simply sets the desired temperature and the system will take care of the rest. A second compressor is powered by a high voltage electric motor during idle-stop operation to ensure that the cabin temperature stays at its set level. Idle-stop operation is only enabled once the cabin has been sufficiently cooled. An electric water pump is also included for heating the cabin during idle stop. Manual Climate Control Civic LX and above models provide air conditioning as standard equipment. The front climate controls on the Civic are mounted centrally on the instrument panel for easy accessibility and feature rotary knobs for temperature settings and fan control. Push buttons allow control of airflow through the various vents inside the vehicle (i.e. defrost, heater, split level, etc.). A micron air-filtration system is capable of filtering nearly 100 percent of particulates over 8 microns in size (the size of most pollen). It can also filter out approximately 40 percent of particulates down to 0.3 microns (about the size of diesel emissions). The high capacity condenser with integral receiver drier runs the liquid refrigerant through a sub-cooling condenser, after the main condenser. The system is efficient and lightweight compared to traditional setups. Progressive Instrument Illumination The Civic's new instrument system uses progressive illumination to establish a "dialog" with the driver. When the door is opened, the instrument brightness turns on at 10 percent – a "welcome" of sorts for the driver. When the key is put in the ignition (encircled with an illuminated ring), the instrument illumination ramps up to 100 percent in one second. When the ignition is turned on, the illuminated instrument needles and enunciator lights come on, indicating all systems are go. Audio Systems Music plays an important role for most Civic buyers, so Honda engineers worked to provide the best audio systems in the compact class. The Civic LX Sedan is equipped with a 160-watt AM/FM/CD audio system with four speakers. The CD player can also read CD-Rs loaded with Windows Media Audio (WMA) or MP3 audio files. Civic LX models and above present audio data on the new i-MID and also add a USB Audio Interface. All systems feature Speed-Sensitive Volume Control (SVC). With SVC, as the car speeds up and exterior noise increases, the audio system automatically raises the music's volume, and then lowers it as the car slows down. If desired, SCV can be deactivated at any time. Civic LX Coupe models have an upgraded audio system compared to the Sedan. The 160-watt AM/FM/CD audio system features six speakers, including A-pillar-mounted tweeters. Civic EX Coupe, Civic EX-L Coupe and Civic Si models provide an even more impressive premium audio system, with 360 watts output from seven speakers, including an 8-inch subwoofer. Civic customers also can listen to music via an auxiliary input jack that enables them to plug their personal audio devices (such as an iPod® or MP3 player) directly into the Civic's audio system. The AUX jack is standard on Civic LX and above sedans and coupes. USB Audio Interface A USB Audio Interface is located in the center console of all models, with the exception of Civic DX. It can read flash drives and compatible digital music devices, such as iPods, that contain MP3 or WMA music files. It is important to note that only the iPod video, iPod nano and other 5th-generation or later iPods are compatible with this system. The iPod shuffle, mini, and older iPod models are not compatible. When an iPod is connected, the Honda logo will appear on the screen of the compatible iPod showing it is ready for use. The iPod or flash drive can then be controlled using the steering wheel-mounted or radio controls. Information such as song title, artist, album art and other information will appear on the Civic's LCD screen. The system will also charge the iPod while it is connected. XM®Radio XM® Radio is a standard feature for all Civic models equipped with the available navigation system and it provides more than 130 digital channels of programming with near CD-quality sound. With XM Radio, Civic owners can listen to their choice of music anywhere in the contiguous 48 states along with in select areas of Canada. XM® programming includes channels devoted to music, sports, talk, traffic, weather, children's programming and entertainment. Of the 130 XM® channels, 69 are commercial-free. When the Civic's audio system plays XM®, the i-MID display screen shows the current station, song title, or artist's name. Audio Feature Summary
Bluetooth® HandsFreeLink® The Bluetooth® HandsFreeLink® interface is designed to offer hands-free operation for many Bluetooth®-enabled mobile telephones. Standard on Civic EX, Civic EX-L, Civic Si, Civic Natural Gas and Civic Hybrid, the system wirelessly connects the driver's cell phone to the vehicle's audio system. This allows the driver to make or answer cell phone calls without removing hands from the steering wheel. The system is compatible with Bluetooth®-enabled cell phones that have the Hands Free Profile (HFP). A list of compatible phones can be found at handsfreelink.com or honda.com. HandsFreeLink® improvements for the 2012 Civic include full manual control, auto import of phonebook and call history, a dedicated Phone button on the head unit and six speed dials linked to radio preset keys (except for models equipped with navigation systems). Bluetooth® HandsFreeLink® now enables audio files to be played through the vehicle's audio system wirelessly with a feature called Bluetooth® Audio. If an audio compatible device is paired it will be added as an auxiliary source on the i-MID's audio screen. This allows the Bluetooth® device's media to be played wirelessly by the audio system. Cell phone devices that support the Advanced Audio Distribution Profile (A2DP) and Audio Video Remote Control Profile (AVRCP) 1.3 allow the display of metadata for artist, album and track name on the i-MID. The vehicle's audio controls for “skip forward” and “skip backward” allow for navigation from track to track. Bluetooth® HandsFreeLink® is designed for easy use. After the driver completes a simple one-time "pairing" process to link the cell phone with the vehicle, Bluetooth® HandsFreeLink® can communicate wirelessly and securely with the driver's cell phone when the phone is within about 33 feet of the vehicle. Once the driver enters the vehicle, the phone can be stored in a pocket, briefcase, purse or a storage bin inside the vehicle's cabin as the call transfers information through the wireless telephone interface. Certain compatible cell phones can also transfer the cellular phonebook into the vehicle through the Bluetooth® HandsFreeLink® system. After the cellular phonebook is transferred, calls can be made by making selections from the registered phonebook on the information screen. Operational features include:
Satellite-Linked Navigation System with Voice Recognition and FM Traffic The latest generation of the Honda Satellite-Linked Navigation System is available on Civic EX, Civic EX-L, Civic Si, Civic Natural Gas and Civic Hybrid and features a 6.5-inch display and a fast 16 G B Flash Memory in place of the DVD-based system used previously. Turn-by-turn driving directions appear on the navigation screen, and on the new color i-MID display, which is positioned high in the instrument panel, close to the driver's line of sight. The system also includes standard FM traffic, which provides constantly updated on-screen traffic incident data for select cities that lets drivers choose faster, less congested routes to get to their destinations sooner. Unlike some other traffic data systems, FM traffic does not require a subscription and entails no extra charges. The navigation system features more than 10 million points of interest and is integrated with the audio system. The voice recognition is capable of recognizing and inputting numbers, street names and cities, in addition to more than 700 commands. Honda navigation systems have long been recognized for their simple, intuitive operation and extensive on-board database. When navigating freeways, a split screen design enhances on-screen information with a "map view" and "3-D" route visualization of freeways simultaneously – which helps make navigation information easier to understand. And now with turn instructions displayed on the i-MID, situational awareness is further improved. The navigation system is integrated with the car's audio system, so driving instructions can be heard over the speaker system, and the voice recognition feature adds a hands-free realm of control to the navigation system. The Honda Satellite-Linked Navigation System uses Global Positioning Satellites (GPS) in combination with detailed information from the vehicle's Flash-based mapping system to pinpoint the vehicle's location and to provide a host of useful mapping and route guidance features. The antenna can utilize up to 12 satellites from a network of 24 global positioning satellites. If the antenna is obstructed by a tunnel, a parking garage or a tall building, an internal gyroscopic system and a speed sensor track the location of the vehicle so that the map information remains current and reliable. The vehicle clock is independently controlled by GPS data, so when time zones are crossed while driving, the clock will automatically set itself to the current time. The navigation system can be controlled by the driver through either the voice recognition system, the touch screen display, or by the joystick at the lower right corner of the screen. The voice recognition system works when the "talk" button (located on the steering wheel) is depressed. When spoken to, the system recognizes commands such as "find nearest gas station," or "find nearest ATM" and can also recognize street names. In the Civic Natural Gas, the available navigation system database includes the locations of compressed natural gas (CNG) refueling stations. The 6.5-inch LCD touch screen allows the driver or front passenger to choose menu options or spell out a word (i.e. address, business name, place, etc.) through a touch-sensitive keypad. The keypad can be set to alphabetical or a QWERTY typewriter-style layout. Alternatively, the joystick can be used to highlight menu options or to highlight specific letters on the keypad to complete a word. A matte finish is used on the display to reduce glare and smudging. For data storage, the system uses a 16 G B flash memory that contains information for the entire United States. Future updates to the navigation system can be made with a flash drive via the Civic's USB port inside the glove box. Flash drives with updated map data can be purchased on-line or by calling a toll free number. Power Windows and Locks Power windows are standard equipment on all Civic models. Civic LX and above models provide auto up and down operation on the driver's window. Power door locks with a customizable auto-locking feature are standard on Civic LX and above models. The auto door lock settings can be configured through the i-MID. Keyless Entry System Keyless entry is standard equipment on all Civic models except the DX. The wave key design has an integrated transmitter in the handle with lock, unlock, trunk open and panic buttons. Engine Immobilizer Complementing the keyless entry system is a standard engine-immobilizer system.
