Mazda says next-gen gasoline engine as clean as an EV, well-to-wheels
Mazda is already working on the successor to its efficient Skyactiv-X motors, and thinks it could make cars as clean as EVs, if you take into account CO2 from electricity production. The automaker believes it can increase the efficiency of the Skyactiv-3 to 56 percent, close to the maximum theoretical thermal efficiency of an "Otto" cycle gas engine, Mazda's Mitsuo Hitomi told Automotive News. If it can achieve that mark, it would reduce CO2 pollution by a quarter, making Skyactiv-3 motors as efficient as EVs on a well-to-wheels basis.
