The electric vehicle can use direct drive or employ a transmission. This is possible because the electric motor produces torque at very low RPM, whereas the internal combustion engine needs usually needs to reach 2,000 RPM before significant torque is generated. The EV can use less gears because it produces torque and horsepower through a larger range of RPM.
A 2 speed power transmission is available for EVs. Besides park it has four speed positions: Neutral, Reverse, High and Low. The transmission has planetary gears and is shifted through internal hydraulic clutches. The park position locks the transmission so the vehicle cant roll, while neutral releases the clutches so the vehicle is free to roll. Reverse changes the output shaft direction allowing the vehicle to back up.
