They are tiny engines, but they get lousy gas mileage and are hard to make emissions compliant. Mazdas new ''Skyactive'' engine technology is about increasing power output while retaining or increasing fuel efficiency.
While they were able to make a good rotary engine, Mazda was never able to get good fuel economy or longevity out of them.
