Wankel rotary engine

  • Mazda RX-Vision Fast and Furious livery

    The Wankel rotary, the peculiar pistonless internal combustion engine design that Mazda built so much of its heritage around, may see a resurgence after all. Earlier reports and remarks from Mazda executives have suggested that while the rotary will make a comeback, it will be relegated to what’s essentially an emergency generator—a range extender for a plug-in electric vehicle that’s expected for the U.S., among other markets. But a report from last week puts the rotary potentially on a higher stage in some versions or vehicles. DON'T MISS: Mazda announces electric lineup...

    A look under the hood of Mazda’s future includes a patchwork of “what if” possibilities and a series of juggled timelines. Mazda is in a tough spot right now with regulators and in finding its place across many global markets. Part of the issue is that Mazda is considered an...

    Mazda's electric car gets patents for rotary range-extender engine

    Recent patent filings suggest Mazda’s next Wankel engine will equip a battery-powered car, not a rear-wheel drive heir to emblematic sports coupes like its RX-7 and RX-8. Mazda has invested more time and money into the rotary engine than any other automaker, so executives are reluctant to let...

    Rotary Engine Lives On In Range-Extended Electric Mazda 2 Prototype

    Mazda is a relative minnow in the auto industry sea, but for such an independent company it punches above its weight in engineering terms. It's still one of few companies to offer a simple two-seater sports car in a world of more profitable crossovers and hatchbacks. It's developed an entirely new...

    Audi A1 e-tron: First Drive Of Range-Extended Electric Car Prototype

    The Audi A1 e-tron was almost a sideshow to our day at the company's future lab tron-experience at Berlin's spectacular and disused Tempelhof Airport. Drives squeezed in over lunch or at the end of the day reflect the A1 e-tron's unfortunate status: Stillborn prototype, rather than fully-fledged...

    Could Range-Extended Cars Save The Rotary Engine? Mazda Says Yes

    While the Wankel rotary engine, Mazda’s power plant of choice for many years, has a fantastic power to weight ratio, it isn’t exactly what you’d call a green engine. As a consequence, since the Mazda RX-8 ended its production in June this year, you won’t find a rotary engine...

  • Rotary engine

    You may have noticed we feature the late Mazda RX-8 rather less often than the Chevrolet Volt range-extended electric car. Considering the final iteration of the four-seat, four-door sports car delivered just 23 mpg highway from its 1.3-liter Renesis rotary engine, it really wasn’t a green car. But Mazda believes that's going to change. WardsAuto.com says the carmaker could come full circle with its rotary engine efficiency and offer an improved version as part of its SKYACTIV technology for more fuel-efficient vehicles. The inherent advantages of rotary engines over piston engines are...

    Electric-Car Range Extender Engines: OK Now, Can Do Better

    Electric cars like the 2011 Chevrolet Volt and 2011 Fisker Karma get around the problem of range anxiety the old-fashioned way: They use gasoline engines. They do it because the battery systems of pure electric vehicles are large, heavy, and expensive, but the range they produce is still...
