About 10 years ago, a certain French company called Furion paired a twin-rotor, 654cc Wankel rotary engine with a 40-kilowatt electric motor to produce a massive 180 hp and 151 lb-ft (205 Nm) of ...

The rotary was the most radical rethink of the combustion engine in over a hundred years — and it paid the price for being different. Mazda introduced the innovative Wankel rotary engine in the 1967 ...

Mazda made a splash in the market in 1990, launching the Eunos Cosmo with the three-rotor 20B engine. Compared with contemporary Wankel rotary engines, the 20B's extra rotor beefed the compact ...

Not only are Chinese carmakers redefining the world of EVs, but one of them is now taking on the Wankel rotary engine. Originally designed by German engineer Felix Wankel and later refined into a ...

Launched in the late 1960s, the Ro 80 wasn't just the world's first mass-produced sedan with rotary power, but also one of the most innovative production vehicles of its era. The rotary motor, also ...

Long before Felix Wankel became synonymous with rotary engines, an inventive Hungarian-American engineer named Stephen M. Balzer secured one of the earliest patents for a rotary-powered automobile on ...

In a world dominated by pistons, the rotary engine was something different for motorists. It was the vision of German engineer Felix Wankel, built on the belief that the up-and-down motion of pistons ...

Automotive engineers have invested countless billions trying to improve upon the humble internal combustion engine, but not all those efforts have translated well. In fact, sometimes, things got weird ...
