As an all-around performance value, it's hard to beat the AWD Impreza WRX wagon. Although the sloped rear profile limits additional cargo capacity, the wagon's extra room is useful for family trips. A standard 230-bhp turbo flat-4 is coupled to a 5-speed manual or 4-speed automatic. The sophisticated AWD powertrain allows the WRX to provide all weather performance and handling. A viscous limited-slip rear differential distributes torque to the wheel with the most traction. Automatic transmission cars get an electronically controlled clutch that varies front/rear torque split as required. A comprehensive set of standard features makes the Impreza WRX Wagon an excellent value.
