Powered by the legendary 305-horsepower 2.5-liter turbocharged Boxer engine, the 2015 WRX STI debuts a new four-door wide-body design, built on a stiffer chassis for even greater handling agility and precision. The Subaru WRX STI provides a rally-bred drivetrain and all-wheel drive handling that is unique to this model. Handling is enhanced with a stiffer chassis, firmer springs and faster steering (13.0:1 ratio).
New for the 2015 WRX STI, Active Torque Vectoring joins an arsenal of the model’s proven handling technologies that includes Multi-Mode Driver Controlled Center Differential (DCCD) Symmetrical All-Wheel Drive, Multi-Mode Vehicle Dynamics Control, and a Brembo® Performance Brake System with Super Sport ABS.
