After decades of making performance engines Mercedes still often makes engines with huge design flaws that make them maintenance nightmares or they simply grenade and destroy themselves at low mileages. Why so many basic design problems?

Yes, we are perfect endothermic engines, but for me they are theoretically and practically outdated "they pollute, they are not efficient and also bulky and heavy, aggravated by the weight of the fuel".

the rotary engine when built with good part can reach 110 to 115% efficiency. want to hear a secrete, the jet engine can do way better. ones a jet engine gets past a certain RPM range, it becomes so efficient it doesn't need fuel anymore and can power other things. that's why certain parts of building a plane is so compartmentalized. there is a lot they want to keep secrete. just think about it, if a plane rotary engine can reach 115% efficiency, the jet engine spines much faster, so what do u think it can do? 200% 500%? i would venture to say the jet engine creates electrical power as well. maybe even say zero point energy. its a beautiful thing the jet engine.
