We’ve covered the engine sound simulator here before, but there’s been one element that’s been missing from the bizarre mix for too long. Yes, the world loves to know what an 11-cylinder engine could ...

Astron aerospace has shown a partial prototype of a new rotary combustion engine it claims runs at an extraordinary 60% thermal efficiency, burning totally clean with zero NOx emissions and nothing ...

The Mazda Cosmo Sport 110S proved the twin-rotor engine could survive years before the RX-7 made rotary performance famous.

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 ...

Over-the-top rotary builds are an enthusiast tradition. Because so few rotary cars have been made, the limits of the engine type haven't been fully exploited by automakers. It's been tuners who have ...

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 ...

In theory, Wankel-style rotary internal combustion engines have many advantages: they ditch the cumbersome crankcase and piston design, replacing it with a simple, single-chamber design and a thick, ...

The rotary engine has been a Mazda staple since 1967. It powered one of the most famous and eccentric Japanese sports car line-ups, the RX-series, until 2012 when Mazda discontinued pure ...

A Wankel engine is a type of rotary engine, but not all rotary engines are Wankel engines. Wrapping your mind around this idea will help you to better understand the similarities as well as the ...

As the aerospace industry seeks to improve pilot training and reduce costs, simulation technology has emerged as a leading method of innovation. One of the most valuable investments in pilot training ...

Forbes contributors publish independent expert analyses and insights. Peter Lyon is based in Tokyo and writes about the car industry. At the Japan Mobility Show two years ago, Mazda unveiled a ...

A bold collaboration aimed to bring research to reality could rewrite the rulebook on sustainable energy. Advanced Innovative Engineering (AIE), the leader in high-performance rotary engines, is ...
