While it wasn’t theÂ only car company to make use of a rotary engine, it was certainly the only one to be competitive with them when pistons and pushrods would easily have sufficed. However, those days are gone. Mazda’sÂ SkyActiv technology is well suited for squeezing out an engine’s true potential, but it doesn’t feel particularly quirkyÂ or unique.
That could change with the company’s second generation of SkyActiv engines.Â Mazda is one of only two automakers planning to introduce a motor with homogenous charge compression ignition (HCCI) sometime next year. If you’re unfamiliar, that’s a direct-injection gasoline-powered motor that uses compression, not spark, to ignite fuel â€” something typically reserved for diesel powerplants.
Mazda expects the HCCI engine to yield a 30 percent improvement in fuel economy over a similarly-sized conventional internal combustion unit.Â The new engine should debut in the Mazda 3 as part of its mid-cycle refresh in 2018, and then expand into other models.
According to the Nikkei Asian Review, the second generation SkyActiv engines should give the Mazda3 fuel economy “approaching 30 km per liter.” While only a rough estimate, that equates to over 70 miles to the gallon â€”Â enough to put hyper-mile hybrids to shame and meet stringent CAFE standards.
Of course, Mazda also plans to mass produce an electric vehicle by 2019Â while it procrastinates on a plug-in hybrid until 2021. The company also remains committed to bringing its extremely emission-friendlyÂ Skyactiv diesel to the North American market.
