>>4610213They are a decent engine and deliver the performance you need with a very low center of gravity. The only piston equivalent engines are boxer engines. However in a performance to performance test, pistons still have a larger advantage. Economy wise they currently are still plagued with issues with oil consumption/fuel and thermal efficency/Co2 emissions.
Over all Piston>rotary, but the Rx7 and RX8 chassy takes full advantage of the rotary powerplant, which is why its such a good car despite its issues.
