Wankel rotary engine

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...

The electric-car revolution may give new life to an old gas engine. On Tuesday, timed to coincide with the Paris auto show, Mazda announced it will add plug-in capability and electric power to all of its models by 2030. Some will be plug-in hybrids or range-extended electric cars—with a...

How Mazda plans to integrate plug-in hybrid and battery-electric vehicles into its range of increasingly efficient gasoline and diesel models is a topic that interests parts of the global auto industry. In 2019, the small Japanese maker will offer a combustion-engine technology never before...

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...

Mazda's new rotary engine will not debut as part of an electrified powertrain, the company's R&D chief says.

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...

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...

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 engines aren't known for their green credentials, but if Mazda's latest plans come to fruition, they may be granted another lease of life. Most frequently seen in Mazda's sports cars over the years, Wankel rotary engines are associated variously with ultra-smooth power, poor fuel economy...

It's all change at Mazda for the next generation of its engine and product lines. The CX-7 SUV and 6-cylinder engines are out, and a wave of efficient Skyactiv engines, light-weight cars and an improved line of rotary engines is in. Robert Davis, senior vice president of U.S. Operations at Mazda...

Oh, the horror, the horror. Once again, the world is coming to an end. No, not tsunamis, or earthquakes, or tornadoes, or plagues. Not even locusts. Nope, it's the evil specter of hybrid technology that will conclusively decimate all of mankind, depriving it forever of driving fun, pleasure, and...

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...

We've loved the concept of the Audi A1 e-Tron concept since its launch at the 2010 Geneva Motor Show last March. It's a range-extended electric vehicle (like the 2011 Chevy Volt) that uses a tiny Wankel rotary engine to run a generator that produces electricity to power the car once its lithium-ion...

With BMW slowly revealing further details of their upcoming Megacity EV and teasing us with the 2009 MINI E, and Mercedes-Benz giving us the A-Class E-Cell, it was only a matter of time before rival Audi hit the roads with their own small EV. Revealed at the 2010 Geneva Motor Show in March, their...

Four months from now, the world's first extended-range electric vehicle will start showing up at dealers. The 2011 Chevrolet Volt will introduce car buyers to the idea of a range-extending combustion engine that turns a generator to power the car electrically. But the generator in an E-REV can be...
