The Subaru Impreza WRX is a high-performance version of the Subaru Impreza. The WRX originally debuted in Japan in 1992. An American version of the vehicle was not made available until the 2002 model year. The current 2nd-generation of the performance-oriented compact was introduced to the U.S. for the 2008 model year. The vehicle competes directly with other sporty compacts, including the Honda Civic Si and Mitsubishi Lancer Evolution.

Inside and out, the Subaru Impreza WRX is designed for maximum performance and handling. The vehicle's facelift in 2008 toned down some of the European-inspired rally features found on the original design. This was done by Subaru in an effort to appeal to a wider audience. The Impreza WRX is available as either a 4-door sedan or hatchback. Dimensions for the vehicle include a length of 180.3 inches (173.8 inches for the hatchback model), width of 68.5 inches and height of 58.1 inches.

The interior of the latest incarnation of the WRX incorporates a roomier feel and more luxurious components. Seats have been modified to provide more back support. Storage capacity in the sedan model is 11.3 cubic feet. The hatchback provides a considerable upgrade in storage, with a total of 44.4 cubic feet available.

The 2009 Subaru Impreza WRX is a carryover from 2008. The 2009 Impreza can be purchased in either hatchback or sedan form, and it comes in base, Premium and STI trims. The standard 2009 WRX and WRX Premium are outfitted with a 2.5 liter, 4-cylinder motor that produces 265 horsepower and 244 lb-ft of torque. A 5-speed manual transmission is the exclusive gearbox option, and fuel economy numbers come in at 18 miles per gallon in city driving and 25 miles per gallon on the highway. The WRX STI drops the sedan platform and substitutes a 305 horsepower edition of the 2.5 liter motor that also provides a ground-pounding 290 lb-ft of torque. A 6-speed manual transmission routes power to all four wheels – all-wheel drive is standard across all editions of the Impreza WRX.
