Mazda is diligently working to save the internal combustion engine from a slow death brought on by electric vehicles. The independent Japanese automaker has been perfecting the ICE for decades with its Skyactiv line, including the Skyactiv-G and new Skyactiv-X. The latter is particularly interesting as it combines the strong points of both a gasoline- and diesel-powered engine without either of their weak points. Skyactiv-X is set to arrive in showrooms sometime in the next year. Nevertheless, the automaker isn’t resting on its laurels.
