are smooth, make lots of power from tiny displacement, rev like superbikes and suffer a fraction of the wear and tear of mechanical parts that conventional piston engines do.Well, because they're high-maintenance, need lots of oil, are easy to flood with fuel, develop next to no torque (which is what you actually need to overtake stuff in the real world) and are very difficult to turbocharge reliably. They're a, which is why even Mazda, long-time friend of the rotary engine, has jacked them in.How could the rotary issues be solved? Maybe, perhaps, the answer is to think big. As in forget two engine rotors, or even three, butup together. Even normally aspirated, it'd sound like a beehive on acid, make 813whp, 530lb ft, and render something retro like, say, a 1970's Mazda RX-4 almost undriveable. Sounds like a plan to us...
