The next-generation SKYACTIV-X gasoline engine is a revolutionary powerplant that combines the free-revving characteristics of a gasoline engine with the fuel efficiency, torque and fast initial response of a diesel unit.

Thanks to its proprietary Spark Controlled Compression Ignition (SPCCI) technology, SKYACTIV-X is set to become the world’s first* commercial gasoline engine to use compression ignition to realize an unprecedented level of sharp engine response and torqueful acceleration combined with higher fuel efficiency and cleaner emissions than ever before. At the same time as pursuing this ideal internal combustion engine, Mazda also developed a new platform, next-generation SKYACTIV-VEHICLE ARCHITECTURE, with increased focus on our human-centered design philosophy to maximize the inherent ability of the human body. Together, these groundbreaking next-generation technologies synergistically support Mazda’s world-renowned Jinba-ittai driving experience.
