2014 Subaru Impreza WRX STi Hatchback The third-generation WRX STi recieved a hatchback variant for the first time. This meant that you could now have a practical WRX, but still have the same fun you would have in the sedan version. Power comes from a turbocharged EJ-series flat-four that produces 305 horsepower and 290 pound-feet of torque.
