    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.

    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.

    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...

    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...

  • AVL rotary-engine range extender for electric-drive vehicles, July 2010

    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 driven by many different things that produce torque. Now AVL Powertrain Engineering proposes that rotary engines make more sense as range extenders than they do for powering cars directly. And AVL is not alone. The Audi A1 e-Tron concept minicar shown at the 2010 Geneva Motor Show last March used...
