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.
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, ...

Do Rotary Engines Need Oil Changes?
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 ...
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 ...
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 ...
