No, it’s not just one part of the engine, it’s the whole thing, as the Renesis 1.3-liter rotary engine that powers this sports car is known to be a gas-guzzling, unreliable machine. Instead of pistons, the rotary engine uses rotors to operate, and over time, they tend to wear down.

What is the main problem with a rotary engine?

The biggest problem with rotary engines was fuel efficiency. Possibly also durability of the seals? It’s nice not to have reciprocating movement of pistons, but you simply cannot get the high compression ratios with rotaries, nor are the combustion chambers ideally shaped for thermal efficiency.
