Subaru Debuts All-New 36-MPG 2012 Impreza® at New York International Auto Show
• 30-Percent Boost In Fuel Economy Makes 2012 Impreza the Most Fuel Efficient All-Wheel Drive Car in America.
• Roomiest Impreza Ever With New Level of Comfort and Refinement
• Same exterior dimensions, but lighter and quicker than previous modelNEW YORK, April 20, 2011
-- Subaru of America, Inc., today introduced the all-new fourth-generation 2012 Impreza® four-door and five-door compact models at the 2011 New York International Auto Show. Debuting bolder, more dynamic designs and an all-new powertrain, the 2012 Impreza models offer a 30-percent improvement in fuel economy over the outgoing versions, along with increased room, greater agility and a higher level of refinement. New amenities, infotainment technology and higher-grade interior materials contribute to a more rewarding driving and ownership experience in the 2012 Impreza, which will arrive in Subaru dealerships this fall.
Powered by an all-new 148-hp 2.0-liter Boxer engine, the 2012 Impreza comes with a choice of a five-speed manual transmission or the second-generation Lineartronic® CVT (continuously variable transmission). The 2012 Impreza will offer the highest fuel economy of any all-wheel drive car in America, with projected EPA ratings of 27 mpg city and 36 mpg highway. Every 2012 Impreza is equipped as standard with Symmetrical All-Wheel Drive.
Offered in base, Premium, Sport Premium, Limited and Sport Limited models, the 2012 Impreza conveys a bolder, more confident design that emphasizes its sporty roots and standard Symmetrical All-Wheel Drive performance. In profile, the 2012 Impreza draws focus to its wheels with powerful arches, a theme that debuted on the 2010 Subaru Legacy®.
The combination of a longer wheelbase and redesigned door and roof trim and front seats yields gains in passenger and cargo room for the 2011 Impreza. The wheelbase grows to 104.1 inches compared to 103.2 in the outgoing model. Vehicle length and width remain the same as before for both sedan and five-door models, yet, thanks to redesigned door panels, the 2012 Impreza offers increased hip and shoulder room. Rear seat passengers gain nearly two inches of legroom. Sedan trunk room and five-door cargo room are both increased, and the five-door now provides a completely flat load floor with the standard 60/40 split rear seatbacks folded.
The windshield is more raked than in the previous Impreza, with the bottom of the A-pillar moved 7.9 inches forward, allowing for a front door opening nearly five inches longer for easier entry/exit. Higher hip points and a lower, flatter instrument panel, along with larger side mirrors, contribute to better visibility from within the cabin.
Engine : 2.0 L., 4-cylinder
Power: 148 hp
Torque: 145 ft-lbs
Richer looking appointments and details abound, including soft-touch materials for the dashboard, door trim and center console armrest. Larger door pockets can hold plastic drink bottles and large maps. Numerous compartments located in and around the center console hold all manner of today's personal items, such as phones, ÚSB drives and MP3 players.
The new 2.0-liter Boxer engine feels even more responsive than the 2.5-liter engine it replaces, thanks to lighter vehicle weight – and especially when equipped with the new CVT, a quieter and more compact version of the CVT that debuted in the 2010 Legacy and Outback® models. Únlike a conventional automatic transmission, which uses fixed gear ratios, a CVT provides infinite variability between the highest and lowest available ratios with no discernable steps or shifts. The CVT continuously and smoothly adapts to performance demand, helping to keep the engine in its most efficient operating range. Impreza Premium, Sport and Limited models with the CVT also feature a 6-speed manual mode with steering wheel paddle shifters, which allow the driver to control the transmission via six pre-set ratios.
Other technologies helping boost fuel efficiency in the 2011 Subaru Impreza include the new electric power steering system, which by itself contributes a 2-percent efficiency increase, and lower rolling resistance tires.
Strengthened suspension components in front and rear -- some inherited from the Legacy -- enhance agility, while new liquid (hydraulic) engine mounts help to damp out vibration. The double-wishbone rear suspension features new, strengthened components and pillow ball bushings for improved ride, straight-line stability, handling and vehicle response.
Building on Subaru's renown for safety (all 2011 Subaru model lines are IIHS 'Top Safety Picks'), the 2012 Impreza was designed to excel under the new, more stringent NHTSA testing regimen. The new body structure makes greater use of high-tensile strength steel and features special stiffening elements at key locations. All 2012 Impreza models add a new driver's knee airbag to the roster of safety features. The passenger-seat front airbag, features a shell-type design with a center groove, thus exposing the passenger to less impact force upon deployment.
All Impreza models for 2012 are equipped as standard with Vehicle Dynamics Control (VDC), which combines stability and traction control functions. Likewise, all 2012 Impreza models are equipped with a standard 4-wheel disc Anti-lock Brake System (ABS) with Electronic Brake-force Distribution (EBD) and the Brake Assist safety system.
Standard comfort and available amenities are increased across the Impreza line for 2012. The base model features a tilt/telescoping steering wheel, power windows, door locks and side mirrors, a 60/40-split fold-down rear seat, outside temperature gauge, a multi-function display with fuel economy information, remote keyless entry system, security system with engine immobilizer, tilt/telescopic steering wheel, variable intermittent windshield wipers and a low windshield washer fluid warning light. Even carpeted floormats, often an option in many cars, are standard equipment in all 2012 Impreza models.
Impreza Premium models add 16-inch alloy wheels, steering wheel audio and Bluetooth® control switches, a rear stabilizer bar for crisper handling, adjustable console armrest, body-color exterior mirrors and chrome interior door handles. The standard audio system in the Premium models features Bluetooth® hands-free phone connectivity and audio streaming, Radio Data Broadcast System (RDBS), iPod® control capability, ÚSB port, 3.5mm aux. input jack and six speakers. An optional All-Weather Package adds heated front seats, heated exterior mirrors and a windshield wiper de-icer.
A power moonroof and a navigation system are available for the Premium models. The new navigation system includes a 6.1-inch touch screen LCD display, voice control, iTunes® tagging, SMS text messaging capability, XM® Satellite Radio and XM NavTraffic (both XM services require subscriptions). Úpdated map data can be downloaded to a personal computer and then transferred into the system via secure digital (SD) card.
The Impreza Sport Premium is a five-door model that combines standard 17-inch alloy wheels and the All-Weather Package with fog lights, roof rails, unique seat fabric and rocker panel spoilers.

Topping the 2012 Impreza range, the Limited and Sport Limited (five-door only) models deliver the highest level of comfort and convenience ever offered in an Impreza. Leather seating, the All-Weather Package and Alloy Wheel Package are standard. A further audio upgrade (above the Premium) features a 4.3-inch display screen and standard HD Radio. The navigation system and power moonroof are options.
2012 SUBARU IMPREZA® POSTS 36-PERCENT GAIN IN EPA COMBINED FUEL ECONOMY
• New 2.0-liter Boxer engine
• New Lineartronic® CVT transmission
• 27/36 mpg EPA ratings with CVT – best of any AWD car in America
• 160+ lbs. lighter than previous Impreza model
• Stiffer chassis and refined suspension tuning for better handling, smoother ride
• Available 17-inch wheels
The 2012 Subaru Impreza backs up its bold new design with a compelling combination of everyday performance, excellent ride comfort and the highest fuel economy of any all-wheel drive car in America. Powering all 2012 Impreza models is an all-new 2.0-liter Boxer engine, teamed to either a five-speed manual transmission or a new, second-generation Lineartronic® CVT (continuously variable transmission).
Significantly, with EPA ratings of 27 mpg city / 36 mpg highway (models with the CVT), the 2012 Impreza offers fuel economy comparable with many front-wheel-drive-only compact models and even some subcompact vehicles. Every 2012 Impreza is equipped as standard with Symmetrical All-Wheel Drive. Notably, all-wheel drive is still rare in the compact segment, and only Impreza makes it standard on every model.
New 2.0-Liter DOHC Boxer Engine
The 2012 Impreza's significant gain in fuel economy over the previous model stems from a through, holistic approach to improve vehicle efficiency, including: 2.0-liter Boxer engine with more efficient fuel injection and valve control technology; new Lineartronic® CVT (continuously variable transmission); reduced vehicle weight; electric power steering reduces draw on engine power (accounting for a 2% efficiency increase); refinements to brake performance, and lower rolling resistance tires.
The 2012 Subaru Impreza models introduce a new 2.0-liter version of the new-generation Boxer engine that debuted in the 2011 Forester. Though smaller in displacement and output than the 2.5-liter engine it replaces in the Impreza models, the new 2.0-liter engine by itself contributes a 10-percent increase in efficiency to the new Impreza. As before, aluminum is used for the cylinder block and cylinder heads (there are two with a Boxer engine).
The new long-stroke configuration optimizes torque across the engine speed range. Combined with the lighter vehicle weight by 100-165 pounds (depending on model and equipment), and the new, second-generation Lineartronic CVT, the engine provides similar performance to the previous 2.5-liter unit.
The new Subaru 2.0-liter Boxer engine produces 148 hp at 6,200 rpm and 145 lb.-ft. of peak torque at 4,200 rpm. Considerable effort was made in order to achieve improvements in combustion efficiency and lower friction. The bore/stroke configuration has changed dramatically from the previous engine. With an 84 mm bore and 90 mm stroke (3.31 in. / 3.54. in.), the new Boxer engine features an 'undersquare' bore/stroke ratio of 1.07 vs. the 'oversquare' 0.8 ratio for the previous 2.5-liter engine (99.5 mm bore x 79 mm stroke).
A longer stroke typically yields better low-end and midrange torque but can also mean a wider engine (in a Boxer configuration). However, thanks to optimization of structural components, the new Subaru Boxer engine's total width is unchanged from that of the previous engine.
The new Subaru engine also departs from the previous engine in its valvetrain, replacing the single overhead-cam (SOHC) with a dual overhead-cam (DOHC) configuration and featuring Dual Active Valve Control System (DAVCS) – variable valve control for both intake and exhaust valves, vs. the previous engine's Active Valve Lift System.
Mounting the fuel injectors directly on the cylinder head (though not injecting directly into the cylinder) has made it possible to limit the amount of vaporized fuel that adheres to head walls and to improve both fuel efficiency and emissions. The engine's main and auxiliary components were all optimized and tuned to contribute to greater efficiency in the 2012 Impreza.New, Second-Generation CVT
The new 2.0-liter Boxer engine feels even more responsive than the 2.5-liter engine it replaces, thanks to lighter vehicle weight – and especially when equipped with the new CVT, a quieter and more compact version of the Lineartronic CVT that debuted in the current-generation Legacy and Outback® models.
Únlike a conventional automatic transmission, which uses fixed gear ratios, a CVT provides infinite variability between the lowest and highest available ratios with no discernable steps or shifts. The CVT continuously and smoothly adapts to performance demand, helping to keep the engine in its most efficient operating range. Impreza Premium, Sport and Limited models with the CVT also feature a 6-speed manual mode with steering wheel paddle shifters, which allow the driver to control the transmission via six pre-set ratios. The transmission also allows 'second gear' starts in order to limit the likelihood of wheel spin on slippery surfaces.
Subaru engineered the second-generation version of its Lineartronic CVT to increase everyday responsiveness. Significantly, the CVT-distinct sensation of engine speed leading vehicle speed has been improved. Incorporating G sensor input into transmission control, the CVT produces a more linear response to the accelerator pedal, reducing the sensation that the engine seems to be accelerating faster than the vehicle. Changes to the chain pitch and transmission cover help reduce noise from the CVT in the 2012 Impreza.Stronger Platform
The 2012 Impreza builds on the Subaru foundation of confident, agile handling and safety for any road, or any weather. The roomiest Impreza ever, the 2012 model retains a trim exterior package for ease of maneuverability. The wheelbase grows to 104.1 inches compared to 103.2 in the outgoing model. Vehicle length and width remain the same as before for both sedan and five-door models.
The addition of high-tensile steel at key structural points increases chassis rigidity, which in turn improves crash-worthiness and provides a stiffer platform for crisper handling. Strengthened suspension components in front and rear -- some inherited from the Legacy -- enhance agility, while new liquid (hydraulic) engine mounts (with CVT) help to damp out vibration. The double-wishbone rear suspension features new, strengthened components and pillow ball bushings for improved ride comfort, straight-line stability, handling and vehicle response.
As a result of a careful and strict approach to structural strength and mass optimization, the roomier and better-equipped 2012 Impreza models are over 160 lbs. lighter than the equivalent 2011 models. Even with its smaller, lighter fuel tank (14.5 gallons vs. 16.9 for the previous model), the 2012 Impreza offers longer driving range than the previous model due to its greatly improved fuel economy.
All Impreza models are equipped with standard 4-wheel disc brakes. As on other Subaru models, the braking system uses a tie rod tandem brake booster that greatly improves rigidity and brake feel. The standard anti-lock brake system (ABS) is a 4-channel, 4-sensor system. Electronic Brake-force Distribution (EBD) enhances braking stability.Symmetrical All-Wheel Drive (Two Versions)
An All-Wheel Drive pioneer, Subaru is the only brand to equip all its models with Symmetrical All-Wheel Drive as standard. Symmetrical All-Wheel Drive is comprised of the Boxer engine and the full-time power distribution system, which varies by model and transmission. (posted on conceptcarz.com)
The aluminum Boxer engine and simple, symmetrical drivetrain layout help to lower the vehicle's center of gravity, which in turn contributes to handling precision. Subaru began offering 4-wheel drive passenger cars 40 years ago and introduced innovative automatic full-time All-Wheel Drive in 1987. In 1997, Subaru became the first brand in the Ú.S. to make All-Wheel Drive standard on all its models.
Subaru offers two different Symmetrical All-Wheel Drive systems in the 2012 Impreza. In models equipped with the 5-speed manual transmission, the AWD system uses a viscous-coupling locking center differential to distribute power 50/50 front to rear. Slippage at either set of wheels will send more power to the opposite set.
Impreza models with the Lineartronic CVT use the Active Torque Split version of Symmetrical AWD. In this system, an electronically managed continuously variable transfer clutch actively manages power distribution based on acceleration, deceleration, and available traction. The Active Torque Split system automatically transfers more power (up to 100 percent) to the wheels with the best grip should slippage occur. Vehicle Dynamics Control
All Impreza models for 2012 are equipped as standard with Vehicle Dynamics Control (VDC), which combines stability and traction control capability. VDC monitors input from the ABS brakes, steering wheel angle, yaw and lateral g-force sensors. The system adjusts individual wheel braking as needed, helping to maintain vehicle control under a variety of driving conditions. In the CVT-equipped models, VDC also actively controls the center differential's power distribution by means of the continuously variable hydraulic transfer clutch. A VDC 'Off' switch is useful for driving out of slushy roads, deep snow or gravel. The 'Off' position deactivates the system's torque-reduction control, while the antilock and traction control remain active.Source - Subaru
