Earlier this year, Mazda debuted what it says is the "world’s first commercially available gas-powered engine to use compression ignition." Mazda announced today that this engine, dubbed Skyactiv-X, is headed to the next-gen 3, a car that'll be previewed as a concept at this month's Tokyo Motor Show.

As we've reported before, the Skyactiv-X engine will use high compression to ignite like a diesel, running a very lean air-fuel mixture and reducing emissions. But when you step on it, the Skyactiv-X acts like a regular supercharged Atkinson-cycle gas engine. The ignition process starts with a spark before the engine's increased pressure is used to heat up the cylinder and ignite the rest of the mixture without further help. Boom!



Mazda will also show a four-door design study previewing its future design direction at Tokyo. Last month, a Mazda VP said this concept is a successor of sorts to the gorgeous RX-Vision sports car concept that debuted in 2015.

Oh, and Mazda will also have a Miata featuring a dark cherry red canopy and auburn Nappa leather upholstery. The automaker calls this special edition the MX-5 Red Top. We will call it neat, wondering when it'll get put it on a ship to the US.
