Why are rotary engines so unreliable?

Due to the long and uniquely-shaped combustion chamber, thermal efficiency of the engine was relatively lower compared to piston-cylinder counterparts. This also often led to unburnt fuel leaving the exhaust (hence the tendency of rotary engines to backfire, which is obviously as awesome as it is inefficient).

Why are RX8 so cheap?

Poor Fuel Economy & Daily Drivability

Another reason why the RX8 is cheap to buy now is because many are put off by the poor fuel economy of the car. Rotary engines might be small in size (and produce substantial power relative to that size) but they have a tendency to be thirsty.

Rotary engine designs are considered to be quieter than piston engines, but they are also costlier, cause more emissions, and use more fuel, a factor that is becoming increasingly important for many buyers. One advantage for rotaries is that they use fewer parts, which means they need auto repairs a bit less often.
