Electric Motor

Grahm siad that we would need about 7kW to power our car.
If that is a good amount of power then keep in mind that electric motors are rated by how much power they can make constantly for a long period of time. A motor that is rated at 7kW might use less than 7kW most of the time while the car is cruising. Also a motor rated at 7kW should be able to produce at least 1okW of power for short bursts (acceleration). The only thing that stops the motor from producing 1okW of power constantly is overheating. So if we want to save weight and money we might be able to use say, a 5kW moter that can produce 7kW under accelleration.
