Mazda is notorious for putting rotary engines under the hood of its cars, but here are six models from other manufacturers ...

A self-propagating series of explosions, contained between the blades of a high-speed rotor, promises a leap in power and efficiency during hypersonic flight – provided this radical new engine ...

Could there possibly be a rotary engine with 12 rotors? The answer is yes, and here’s everything we know about it including how much HP it could have.

How do wave rotor engines work? The wave disk engine is a new implementation of wave rotor technology (think micro turbines). The first successful realization of a wave rotor was developed in the ...

A new family of engines aims to harness the power of detonation shockwaves to create ever-faster rocket engines. One of these engines—known as a rotating detonation engine (RDE)—has shown some ...

Here we have a massive, triple-turbocharged, 12 -rotor engine that revs to 9,000 rpm and produces the most outrageous noise I’ve ever heard from an internal combustion power plant.

Rob Dahm’s adopted custom 12-rotor Wankel engine project needs a lot of detail work and some hefty reengineering before it can be pushed to the maximum.

Mazda is known for its innovations in mass-produced rotary engines in sports cars like the RX-7, but it wasn't exactly the first to utilize Wankel's design.

Rob Dahm brings a 12-rotor engine project to life, delivering an insane rotary engine that sounds futuristic.

“NSU Ro80: The Complete Story,” by Martin Buckley details the West German wondercar two decades ahead of its time, undone by its rotary engine.
