Ah yes, rotor to piston competition some very valid points are made so far.
My opinion on this is that rotary engines should be in cars only if plain on racing it.
Normal everyday driving on a rotary is frustrating sometimes due to no torque, BUT if you want to have a car you need to go fast and throw around corners, it’s really hard to beat a rotary. Simple to get 10k rpm’s, an engine that I personally can pick up without the need for an engine hoist (weighs about the same as a pony keg), and the engine design itself helps lower the center of gravity (half of it is below output shaft), and due to how short the engine is, allows the placement for the engine/transmission to be placed to get a perfect 50/50 distribution
