The world of automotive engineering is filled with innovation and experimentation, leading to some rather unusual engine designs that made it to production, albeit briefly. These engines often broke ...

A German engineer, Felix Wankel, is credited with developing the world's first rotary engine in the 1950s. Wankel rotary engines use a triangular rotor spinning in a semi-oval case on an eccentric ...

It is very rare that i get excited about any alternative technology with huge promises, but this looks really awesome: Oh it probably has been invented a long time ago just it didn't work very well.

Rotary engines such as the Wankel have strange shapes that can be difficult to machine (as evidenced by the specialized production machines and patents in the 70s), which means it lends itself well to ...

When I wrote about Mazda’s attempt to create the perfect range extender, I mentioned I wanted to examine the ideas that seem to be closer to that goal. Unfortunately, the Japanese company’s attempt ...

Once again Mazda lives up to its reputation as a brand for unconventional solutions. Proof is the new electric MX-30 R-EV equipped with a range extender powered by a Wankel engine. This rotary piston ...
