A rotary engine does rev higher. Its actually a different engine technology. Instead of pistons, they use a sort-of triangular shaped "rotor" to turn the driveshaft. I had an '87 RX-7 before my ex sold it for a (gag!) Protege. It was the base model, and the engine made 140hp. Damn, I miss that car.....
