In 2001, Subaru changed the face of the performance market with the introduction of the original WRX, a car that could deliver turbocharged, rally-bred performance in any driving condition. The all-new 2008 Subaru Impreza WRX now rides on a 3.7 inch longer wheelbase that improves ride, interior space and utility. Power is provided by a 2.5-liter flat-4 Boxer engine delivering 224 horsepower. The Impreza WRX is now available in two new body styles, a 4-door sedan and a 5-door hatchback.
