A car is not an aircraft, that's all I can say about that. A bolt used in an aircraft has to pass more tests than one in a car would
I love the idea of rotory, even though I have never owned one before. But I understand some common issues because I've done some research and a friend of mine is a rotory fanatic
The general idea being rotory uses less moving parts (fewer areas for failure), they rotate as opposed to coming to a complete stop 4 different times during a cycle (so the redline is seemingly endless), and they pack a lot of punch for their size.
Common issues being they are basically made to burn oil, even though the engine itself is only 3 moving parts all of the components included in the wankel twin turbo became multiple failure points with cooling, apex seals, etc, and of course 1.3 liters gets worse gas mileage than a dodge viper idle at a stop light with the ac running.
One day I still hope to own an fd (one of many in my "reasonable" dream car garage). And I guess technically in about 3 years they will no longer need to go throughemmission inspection because of the whole 20 year old classic car thing
