The Impreza forms the basis of the Subaru World Rally Championship (WRC) competition car, and customers benefit from the car’s robust construction and All-Wheel Drive agility in all driving conditions. A 173-hp Boxer engine makes Impreza one of the most powerful cars in its segment. Yet, these All-Wheel Drive models return admirable fuel economy that’s comparable to some two-wheel drive models: an EPA-estimated 22 mpg in city driving and 29 mpg highway for the 5-speed manual transmission, and 23/28 mpg for the optional 4-speed automatic transmission.

The Impreza has been recognized as a safety leader, garnering the highest award from the Insurance Institute for highway Safety (IIHS) – Top Safety Pick, Gold – in the small car segment, achieving the highest rating (“Good”) in frontal offset, side and rear impact tests. All Impreza models feature a 4-wheel disc Anti-lock Brake System (ABS) with Electronic Brake-force Distribution (EBD), the dual-stage Subaru Advanced Frontal Airbag System, and front seat head/chest side-impact air bags.

For 2007, the Outback Sport Special Edition returns with revised equipment, including an automatic climate control system, a 240-Watt total output AM/FM premium stereo with 6-disc in-dash CD changer, six upgraded speakers and a sub-woofer, plus standard SIRIUS Satellite Radio. Also on the Outback Sport Special Edition, the ashtray has been replaced with an auxiliary audio input jack for connecting iPods and similar music players for playback through the audio system. On Impreza 2.5 i models and the standard Outback Sport, a storage pocket has replaced the ashtray. Interior trim revisions include a new soft-grip steering wheel design and new shift handle design.

The distinctive Subaru front-end design for Impreza features a three-section mesh-type grill inspired by the company’s aircraft heritage, plus boldly styled headlights with smoke-tinted lenses. Sedan models feature wide-body fenders and side spoilers. The wagon models have their own flared fender design and also feature side spoilers. An aluminum hood reduces weight over the front wheels on all Impreza models.

The Impreza 2.5 i Sedan and Sport Wagon models offer outstanding value in a segment where All-Wheel Drive is a rarity. Both models are equipped with sport-tuned suspension, standard 16-inch alloy wheels and sport-design front seats. The generous standard equipment makes the Impreza 2.5 i models among the best-equipped cars in their class: Anti-lock Brake System (ABS), air conditioning, power windows, mirrors and door locks, remote keyless entry system, AM/FM stereo system with single-disc CD player, tilt-adjustable steering column, security system, an outside temperature gauge and variable intermittent windshield wipers.

The Impreza 2.5 i Sport Wagon offers excellent utility and versatility, providing 27.9 cu. ft. of cargo space with the 60/40-split rear seatback up and 61.6 cu. ft. of space with the seatbacks folded down. Utility bars built into the cargo area sidewalls enhance versatility in wagon models.

Outback Sport – The Sporty Crossover

Outback Sport, based on the Impreza 2.5 i Sport Wagon, helped usher in the crossover category over a decade ago. Outback Sport styling is highlighted by new-for-2007 Urban Gray Metallic lower body color, side moldings and bumpers, plus projector-beam halogen fog lights. The Outback Sport Special Edition continues for 2007 with its high-value package of additional amenities. Symmetrical All-Wheel Drive, 4-wheel independent heavy-duty raised suspension and 16-inch aluminum alloy wheels with 205/55 R16 all-season tires give Outback Sport all-road, all-weather capability. Standard features are shared with the Impreza 2.5 i Sport Wagon and add a 12-volt cargo area power outlet, roof rails with cross bars and a rear bumper step pad. 

Boxer Powerhouse

The naturally aspirated 2.5-liter 4-cylinder Boxer engine that powers all Impreza 2.5 i and Outback Sport models is among the most powerful in its displacement category, with 173 horsepower at 6,000 rpm and 166 lb-ft. of peak torque at 4,400 rpm. The i-Active Valve Lift system helps to ensure responsive performance at all engine speeds. Using oil pressure generated by engine speed and load, the i-Active Valve Lift system varies lift on one intake valve by locking the tappet into a higher position by means of a transverse pin. The effect is that of having two separate tappets to act on the camshaft lobe operating the intake valve.At low engine speeds the two intake valves open at different levels, causing a swirl of air and fuel and boosting torque. At higher speeds, both intake valves are opened in the “high” position to increase horsepower.

A smooth-shifting 5-speed manual transmission is standard on all Impreza 2.5 i and Outback Sport models. The optional 4-speed direct control electronic automatic transmission features an advanced adaptive shift control system that adjusts transmission shift points based on driver input and vehicle load to optimize engine performance. The slope control feature provides engine braking on declines. A slip-type lockup torque converter provides semi-locking engagement in third and fourth gears and then full lockup in fourth once cruising speed is reached. The automatic transmission automatically and transparently selects between “Normal” and “Sport” modes in response to the driver’s throttle input.

Advanced Safety Construction

The Subaru Ring Frame Reinforced body structure provides Impreza models with outstanding protection in many types of collisions. A hydroformed front subframe and side sills along with tailored-blank welded B-pillars provide an exceptionally strong structure. The high degree of rigidity contributes to sharp handling response and smooth ride quality while helping to reduce interior noise.

All 2007 Impreza models are equipped with the Subaru Advanced Frontal Airbag system and standard front seat head/chest side-impact air bags. The driver’s side front air bag deploys according to the driver’s proximity to the steering wheel, as measured by a sensor on the seat track. In the passenger side front seat, a sensor module detects weight on the seat – first determining if it’s occupied, and if so by a child or adult – to control air bag deployment. As part of the system, the dashboard features an “Airbag” indicator light.

On all Impreza models, the standard 4-channel / 4-sensor Anti-lock Brake System (ABS) incorporates Electronic Brake-force Distribution (EBD). This system enhances braking performance and stability by actively optimizing braking force between the front and rear wheels according to how the vehicle is loaded with passengers and cargo.

In all Subaru models, the front 3-point seatbelts integrate electrically triggered pre-tensioners and force limiters. Active front seat head restraints in the Impreza 2.5 i and Outback Sport models are designed to help reduce whiplash injury in a rear collision. The safety brake pedal system is designed to yield during a serious frontal impact in order to help reduce injury to the driver’s lower limbs.

Two Types of Symmetrical All-Wheel Drive

Standard Symmetrical All-Wheel Drive forms the common core technology on all Subaru models. With more brands adding All-Wheel Drive, it is worth noting that Subaru introduced four-wheel drive passenger cars more than 30 years ago and automatic full-time All-Wheel Drive 20 years ago. In 1997, Subaru became the first brand in the U.S. to make All-Wheel Drive standard on all models. 

Symmetrical All-Wheel Drive is a complete system comprised of the horizontally opposed (Boxer) engine and the full-time power distribution system that varies by model and transmission. The aluminum Boxer engine and simple, symmetrical drivetrain layout help to lower the center of gravity, which in turn contributes to precision handling response. 

The Impreza 2.5 i and Outback Sport lines feature two versions of Symmetrical All-Wheel Drive, both of which power all four wheels all the time and can transfer more power to the wheels with the best grip. Models equipped with the 5-speed manual transmission utilize a viscous coupling locking bevel-gear center differential that distributes power 50:50, transferring more power to the wheels with the best traction should slippage occur.

In models with the 4-speed direct control automatic transmission, an electronically managed continuously variable transfer clutch actively manages power distribution based on acceleration, deceleration and available traction, also transferring more power to the wheels with the best grip should slippage occur. Control logic in the automatic transmission AWD system enhances stability by monitoring individual wheel speeds and reacting more quickly to wheel slippage. The control logic also helps to improve tight corner braking, contributing to more neutral handling response (reduced understeer and oversteer)
