Mazda reportedly will use the new HCCI engine technology in the next Mazda3 model.

Just days after Mazda announced plans to partner with Toyota on the development and production of new battery-electric vehicles, the smaller automaker said it is getting ready to launch a new breakthrough gasoline engine that could give hybrids a run for the money.

Known as a homogeneous charge compression ignition, or HCCI, engine, what Mazda plans to call the Skyactiv-X has been a long-held goal of many major manufacturers for decades. It essentially combines the best aspects of gas and diesel engines to deliver, among other things, extremely good mileage with low emissions.

Barring a sudden shift by the new Trump Administration, automakers are facing a tough federal fuel economy target for 2025, and that has them looking at a variety of ways to deliver book mileage gains over the next few years.

Along with various battery-based technologies, a number of exotic internal combustion technologies are vying for acceptance, including a concept known as the homogeneous-charge compression ignition, or HCCI, engine. Combining attributes of the diesel but powered by gasoline, and promising major improvements in efficiency, HCCI may finally be ready for prime time.

According to a report by Japan’s Nikkei Asian Review, Mazda and another, unnamed manufacturer plant launch an engine using HCCI technology late in 2018. Set to be used in the little Mazda3, the new SkyActiv engine is expected to deliver as much as a 30% bump in fuel economy compared to a comparable, conventional gas engine.
