http://www.putnamsubaruofburlingame.com/2015-subaru-wrx.htm 888-697-0962 The 2014 Subaru Impreza WRX and WRX STI are a family of high-performance sedans and hatchbacks. Based on the previous-generation Impreza and inspired by Subaru's years in international rally competition, these cars are aimed at serious driving enthusiasts who spend their weekends carving up back roads and tearing up racetracks. The base WRX has a turbocharged, 2.5-liter "boxer" four-cylinder engine rated at an impressive 265 horsepower. The STI uses a higher-performance version of this engine that makes 305 hp. In either case, getting the power to the ground is no problem thanks to standard all-wheel drive. The addition of front and rear limited-slip differentials on the STI translates to ridiculous grip, making it a cult favorite among car enthusiasts who regularly drive in foul weather.
