What are the export rules in the united states regarding motor engines?

Mitsubishi also developed the Evolution MIEV, based on the Evolutions IX's chassis but with four electric motors connected to the wheels as a test bed for the Mitsubishi In-wheel Electric Vehicle (MIEV) next-generation electric vehicle. The in-wheel engines use a hollow doughnut construction to locate the rotor outside the stator, unlike other electric motors where the rotor turns inside the stator. The result of this is a lighter engine which translates into lower unsprung weight in a system where the engines are mounted in the wheels. Each in-wheel engine produces a power output of 68 hp, thus giving a combined output of 272 hp, comparable to that of regular, gas powered Lancer Evolutions. The car subsequently competed in the Shikoku EV (Electric Vehicle) Rally 2005.
