2007 Subaru Impreza WRX review

Subaru Impreza WRX review:

Subaru of America, Inc., which last year introduced a restyled, re-powered Impreza WRX line, including two new models, adds a number of audio enhancements to the 2007 models. The All-Wheel Drive WRX shook up the sport compact segment when it was first introduced in the U.S. for 2002 and continues to stand as the performance value standard for this category.

The 2007 Impreza WRX is offered in five versions: the WRX TR Sedan; the standard WRX Sedan and Sport Wagon models, and the WRX Limited Sedan and Sport Wagon models. All WRX models are powered by a 224-hp turbocharged/intercooled 2.5-liter Boxer engine, and all WRX models back up their exciting engine performance with specially tuned suspension, 17-inch alloy wheels, and a powerful 4-wheel ventilated disc brake system.

Responding to customers’ evolving mobile audio performance needs, Subaru has upgraded the standard audio system in WRX and WRX Limited models for 2007. The standard 120-watt AM/FM premium stereo, which includes a 6-disc in-dash CD changer and six upgraded speakers, now offers MP3/WMA CD playback, a new audio input jack and SIRIUS Satellite Radio Capability. The audio input jack, which can accommodate an iPod or similar portable music player, replaces the ashtray, and a 12v power outlet replaces the lighter socket. Interior trim revisions enhance the feeling of quality in the Impreza WRX and include a new steering wheel and shifter handle design.

Three Levels of WRX Performance Value

With an emphasis on pure performance, the WRX TR marks the entry point to this legendary sport-compact. Available only as a sedan, the WRX TR is identical to the standard WRX Sedan in terms of performance specification, substituting value-oriented feature content and exterior trim from the Impreza 2.5 i Sedan.

The WRX TR buyer does not give up comfort and convenience, however, as the extensive standard equipment list includes air conditioning, power windows, power mirrors and door locks, leather-wrapped steering wheel, AM/FM stereo system with single-disc CD player, remote keyless entry, security system with new engine immobilizer, an outside temperature gauge and carpeted floormats. (See comparison below.) Subaru dealers offer a range of Genuine Subaru Accessories that the WRX TR buyer can add in, all covered under the standard limited warranty. Audio upgrades are among the choices.

224-bhp Turbo Powerhouse

The 2.5-liter WRX turbo engine shares its architecture and technology with the WRX STI engine. The double overhead-cam (DOHC) 2.5-liter horizontally opposed (Boxer) 4-cylinder engine is based on a specially reinforced semi-closed deck engine block. The WRX engine produces 224 horsepower at 5,600 rpm and 226 lb-ft of peak torque at 3,600 rpm. Aluminum alloy pistons and forged high-carbon steel connecting rods help ensure consistent and reliable performance under all driving conditions. The functional hood scoop provides a stream of fresh air to the engine-mounted intercooler.

Upgraded Suspension and Brake Systems

The sport-tuned 4-wheel independent suspension in the Impreza WRX provides an excellent balance of handling response and compliant ride quality. The suspension is particularly adept at dealing with road imperfections, ensuring steady tracking even through bumpy curves. The quick steering ratio yields 2.6 turns lock-to-lock, and the steering has been tuned to provide the driver with an ideal amount of road feel.

All WRX models roll on standard with 7-spoke 17 x 7-inch aluminum-alloy wheels with 215/45 R17 all-season performance tires. The powerful brake system employs ventilated discs front and rear -- 11.5-inch diameter in front with four-piston calipers and 11.3-inch diameter in the rear with two-piston calipers. Painted red and featuring the SUBARU name in white, the calipers also make a strong visual statement.

Two Types of Symmetrical All-Wheel Drive

Impreza WRX has built a reputation as the sport-compact for all seasons, thanks in large part to standard Symmetrical All-Wheel Drive that provides both a performance advantage and serves as an all-weather handling aid. In models with the standard 5-speed manual transmission, the AWD system uses a viscous coupling locking bevel-gear center differential integrated into the transmission case. This full-time AWD system distributes engine power 50:50, transferring more power to the wheels with the best traction should slippage occur.
