You'd think measuring an engine's displacement would be simple, but there's a long history of trying to figure out how to categorize the Wankel.

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 ...

More energy efficiency means four, rather than six, open rotor engines Airbus’ latest hydrogen airliner concept features four, rather than six, open rotor engines.

For more than a decade the name Wankel has popped up whenever car enthusiasts start talking about advanced-design automotive powerplants. The theory of the Wankel engine goes back to 1954 when Dr.
