Despite just showing off the new 2015 Legacy at the Chicago Auto Show, Subaru has some changes incoming. Car & Driver reports that the automaker is working on a replacement on 3.6L flat-six that will appear the mid-cycle refresh, most likely happening in three years. The new flat-six engine will be 3.0 liters and pack more power than the current 256 horsepower from the 3.6L. Its unknown if the engine will have direct-injection or a turbocharger.
Also, Subaru is considering dropping in the direct-injected and turbocharged 2.0L FA boxer-four engine that is found in the Forester XT and WRX. No timeframe has been set if given the greenlight.
