that engine is not better its just different. just cause its a rotary dosnt make it any better than a normal piston engine. and anyways oly mazda has those, the best cars in the would donsnt use rotary. and i heard that rotary has high rpm but ends up wearing out really fast because once that triangle stuff wears out theres a leak between the "cylinder" part thingy. unlike piston engines where if the cylinder wears out there are still multi layers of piston rings sealing out the cylinder.

Has there been a single reliable rotary engine made? I knew the RX7 engines had to have the seals replaced every 30,000 miles or so and I don't know if the RX8 is much better.
