How does Mazda have the mental energy and monetary budget for their endless series of fruitless journeys into weird forms of combustion? They still haven't made that Skyactiv-X thing work, their Miller cycle engines never worked right even though everyone else now makes Miller cycle engines, and rotary engines are only good for the track where the owner is willing to rebuild it hourly.

- threemux 3y agoThe "Skyactiv-X thing" absolutely works and is available on Mazda 3s in Europe now. It doesn't work in the US because of our very stringent NOx emission rules (which, incidentally, is one of the reasons diesels are less popular here). I'm not aware of Mazda trying a Miller cycle engine outside of one trim level on the Millenia. I have heard that their experiments with that helped the development of their Skyactiv engines in general though. I'm also not aware of anyone else making Miller cycle engines currently. Perhaps you're thinking of Toyota's heavy use of the related but not the same Atkinson cycle engine.
