Why do rotary engines rev so high?

Rotary engines are also known for revving high, and that’s because in eschewing pistons altogether, they don’t have any reciprocating mass, just rotational mass. You also need lots of air, which is why the Honda S2000 employs variable lift on its intake valves.

Do rotary engines make torque?

Rotaries also tend to produce about as much torque as a screwdriver and seals tend to be a big problem after a while if you live in a colder climate.
