Surprise, surprise - not all Imprezas are turbocharged WRXs. For less sporting types, Subaru does indeed sell a base Impreza, which for 2008 features a 2.5-liter, single overhead cam, Boxer four-cylinder engine mated to either a five-speed manual or four-speed Sportshift automatic transmission. Output registers 170 horsepower at 6,000 rpm and an equal amount of torque at 4,400 rpm. Symmetrical all-wheel-drive is a Subaru family trait, and as such is included as standard fare on the 2008 Impreza. Behind the scenes are a suspension system composed of struts up front and double wishbones out back, four-wheel antilock brakes, and 16-inch alloy wheels rolling on 205/55R16 tires.
