The 2008 Subaru Impreza was officially released today, June 5, in the Japanese market. While Subie didn’t hold any surprises in terms of the JDM (Japan Domestic Market) Impreza’s appearance, they did however turn up for the book in terms of what’s hidden under the hood scoop of the S-GT, or as the rest of the world knows it, WRX; there’s no 2.5-litre Turbo boxer here as we wrongly presumed.Instead the S-GT wears a 2.0-liter Turbocharged 4-pot boxer delivering 250Hp @ 6.000 rpm and a maximum torque of 33,4 kgm @ 2.400 rpm. Comparatively, the US Spec WRX’s 2.5T has an output of 224Hp @ 5.200 rpm and a max torque figure of 31,2 kgm @ 2.800 rpm. This twist in events with the presentation of the 2.0-liter Turbo S-GT kinda mixes things up for European spec models as the current WRX wears a 2.5-liter Turbo engine. And that is if Subie imports the WRX in
Anyway, along with the S-GT Subaru also presented the base 15S and 20S versions fitted with 110Hp 1.5-liter and 140Hp 2.0-liter normally aspirated boxer engines respectively, both of which will be available in
Developed around the concept of new and more refined designs for comfort plus performance, the third-generation Impreza features streamlined “5-door packaging”, while it offers a rewarding and safe ride enhanced by Subaru Symmetrical AWD (
The new Impreza has been developed under the theme, “Providing a fascinating Subaru distinctive value.” In accordance with Subaru’s philosophy, the core mechanism of Subaru Symmetrical AWD (
Since its debut in 1992, the Impreza has earned worldwide popularity for its agile and sporty performance, compactness, convenience, and utility.

• By shortening the rear overhang, a streamlined flowing form is obtained while roominess is also secured through the vehicle’s extended height, width and wheelbase.
• The all-new double-wishbone rear suspension makes room for a wider and deeper luggage compartment, improving the utility of the car. The wide and flat load floor can accommodate two Tour size golf bags or five carry-on bags.
• The driver’s seat lifter and tilt steering that allow flexible adjustments for drivers are equipped as standard on all models. Telescopic steering is also equipped on the S-GT model while an option on the 15S and 20S models.
• The height of the front wipers is lowered to achieve better visibility over the front hood for the driver.
• Rear quarter glasses and rear gate glass shape is designed for the better, safety visibility.
• Larger door openings afford improved ingress and egress, and the rear doors open 75 degrees to allow for better rear seat access.
2. Design
a) Exterior design
• A flowing line from the tip of the front hood through the rear window, as well as the short rear overhang, highlight the agility of the car.
• Sweeping character lines on both sides and well calculated panel curves reflect light and shadow in harmony.
• Impreza’s sporty image is stressed in all models by projected front fenders and rear quarters; standard roof-mounted spoilers that house LED brake lights; and LED rear combination lamps that comprise brake lights, directional lights and back lights.
• The 3-dimensional design of the projector headlamps expresses functionality.
• Nine exterior colors are available.
b) Interior design
• Aluminum-look insets in the center panels through door trim add a sporty feel and airiness to the car.
• The vehicle information display, which constantly shows outside temperature, average mileage and time on the digital clock, as well as a navigation screen and audio display, are placed nearer the top of the dashboard for improved visibility and functionality.
• New urethane materials are used in the front seat cushions to better absorb vibrations during a ride. The driver’s seat incorporates newly developed seatback springs that support the driver’s back and hips to help maintain a comfortable driving position.
• When the ignition key is turned on, the needles of three meters in the instrument panel swing up to their maximums and quickly fall back to their original positions – A Subaru tradition that - gives a boost of excitement for the driver starting the car. The instrumental panel also comes with an Info-Eco Indicator that lights up when running on low fuel consumption to encourage mileage-conscious driving.
• Two interior colors are offered on the 15S and 20S models: an ivory tone that accentuates openness and light; and off-black, which highlights both sportiness and elegance.
3. Powertrain
a) 1.5-liter DOHC engine (15S) and 2.0-liter SOHC engine (20S)
• The equal length/constant pulsation independent exhaust system substantially elevates exhaust efficiency through reduced interference between cylinders, which helps deliver optimal torque in various ranges of speed.
• The Active Valve Control System (AVCS) hydraulically controls timing in the intake valves and helps to increase combustion efficiency and improve low-end torque on the 15S.
• Various parts of engine employs friction-reducing technologies, including lowered load in the valve springs, mirror-surface machining, and molybdenum coatingon the valve lifters. Fuel economy and emission reduction are greatly improved on the 15S.
b) 2.0-liter turbo engine (S-GT)
• The Dual Active Valve Control System (Dual AVCS) hydraulically controls timing in both the intake and exhaust valves, which helps increase combustion efficiency and improve low-end torque, and ensures linearly responsive acceleration to depressed pedal movement.
• The equal length/constant pulsation independent exhaust system substantially elevates exhaust efficiency through reduced interference between cylinders, which helps deliver optimal torque in various ranges of speed.
• A tumble generated valve (TGV) has been installed in the intake manifold, boosting combustion efficiency by controlling the intake flow. It improves efficiency particularly at the time of engine ignition.
• Also adopted is a secondary air system that forces air into the exhaust port to burn out any gasoline remaining in it. The system helps eliminate harmful substances when the powertrain is still cool, and it promotes early activation of a catalytic converter.
• A new compact turbine boasts quicker response. After optimization of the shape of its turbine housing, the turbo unit has been greatly improved to deliver ideal output from low speed to high speed ranges.
• A liquid-filled engine mount has been applied to reduce noise levels and improve ride comfort. The weight of the engine mount bracket has been reduced by utilizing plastic material.
c) Transmissions/AWD (
• Automatic transmissions have been modified for faster, more accurate, responsive shifts, while fuel economy is improved through reduced friction. AT models come with SPORTSHIFT* mode in which a driver can enjoy manually changing gears.

• By choosing the AT Select lever and ECO Switch in the AT models, 3 modes of driving are available: Eco; Sport; and Manual.
• The N Control System on AT models automatically shifts the transmission back to neutral from driving positions after the brake pedal is depressed for some time, as when waiting at a traffic light.
• The Active Torque Split AWD system is mounted on AT models. MT models come with the center differential AWD system with viscous LSD (limited slip differential).
4. Chassis / Body
• The lower center of gravity, enabled by the Boxer engine, has been enhanced by mounting the engine front 22 mm lower on the chassis, thereby further improving stability.
• The strut-type front suspension is supported by newly designed front cross members. Employing box-shaped steel tubing, the new cross members further support the suspension, as well as improve crash worthiness.
• Thanks to these high-strength cross members, subframe parts have been largely eliminated, making the front floor section much lighter and enabling better handling and improved maneuverability.
• The newly designed double-wishbone rear suspension effectively absorbs shocks from road surfaces, ensuring high levels of ride comfort and agile handling as well as effectively lowering noise levels.
• The brake system employs tie rods for the brake booster, ensuring steady braking and control.
• The hill-start assist function maintains the braking function one second after the brake pedal is released in case of starting a car on a hilly road. (Available on the S-GT MT model with Vehicle Dynamics Control, VDC)
• Streamlined body construction and the extensive use of high-tensile steel, including 590 MPa–level steel for major body frames, the new Impreza has achieved both high body rigidity and a weight reduction of 20 kg.
5. Safety
