🚖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.
