We covered Japan's upgraded Subaru Impreza, which naturally has everybody questioning a new WRX, the present fourth-generation on sale since 2014. According to a story in Japan's Best Car magazine, the 5th generation arrives late next year with a new platform and engine as part of the car manufacturer's Japanese-market overhaul of the WRX STI, JDM-only WRX S4, and Levorg wagon. The STI is anticipated to change from the current turbocharged EJ20 boxer-four to a direct-injection FA20 boxer-four engine with an output of around 315 horsepower. Note, the Japanese-market WRX STI utilizes a 2.0-liter engine, and the U.S version gets the 2.5-liter EJ257 with 310 hp. The U.S.-market WRX (sans STI) already uses the turbo FA20, but it makes 268 horsepower.
