What is the most powerful rotary engine?

Garvin is an endurance powerboat racer who has twice set the record for the run from New York City to Bermuda, and he’s built one of the craziest engines we’ve ever seen. It’s a 12-rotor Wankel, which, for reference, is three times the number of rotors found in Mazda’s Le Mans–winning 787B.

Why did rotary engines never catch on?

The fundamental design flaw of having a moving combustion chamber as on a rotary also means that part of each fuel charge is still burning when it gets fired down the exhaust, meaning wasted energy, increased fuel consumption and dirty emissions, not helped by the necessary total loss lubrication system which means oil …
