Discover how Mazda’s 13B-MSP Renesis evolved, its tech breakthroughs, and the issues that defined it, plus how it connects to today’s new single-rotor 8C engine.

A company called Changan has developed a new rotary engine, according to reports from CarNewsChina. It’s called the R05E, and ...

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 ...

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, ...

Wankel rotary engines, typically but not exclusively found in Mazdas, certainly lean on the "quirkier" side of modern powertrain systems, made quirkier because most rotary-powered cars on the road ...

The electric motor might carry the hype banner at the moment, but some minds remain convinced that there's plenty of innovation left to be extracted from internal combustion. AIE is one of the rotary ...

Wankel engines first saw use in production cars as early as 1964 — and not even in a Mazda, but rather in an NSU. That little single-rotor powerplant quickly evolved into the more typical two-rotor ...

Like it or not, the combustion engines that have driven our world forward and sideways for more than a century now are about to leave the scene. Not because they're no longer effective, but because ...
