Technically, electric cars don’t have engines; they have motors. As much as we hear motor and engine used interchangeably, they are not the same. For example, engines are under the hood of just about every car on the road. They use a fuel, like gasoline or diesel, that combusts to perform work. Motors are used in electric cars, power drills, R/C cars, etc., and use electrical energy (supplied by a battery) to perform work. There are multiple types of electric motors.
We’ll take a quick look at the Tesla roadster, seeing as it’s currently the sole electric-only car available in the U.S. Powering the Tesla is a large electric motor, which is in turn powered by a 375-volt battery.
Tesla’s electric motor makes 185kw, which is the equivalent of roughly 250 hp. By comparison, Toyota’s Prius gasoline/electric hybrid uses a motor that makes 50kw, around 67 horsepower.

Tesla motor's electric motor is an induction motor, which is different from the ones used for the Priusd. i believe the pPrius uses an interior permanent magnet motor, which is a synchronous motor. Induction motor is asynchronous, which means it runs at a slip, or a speed a few RPM's slower than the synrchronous speed. The main difference to Tesla is that it is a lot cheaper because magnets are expensive. The motor is driven by an electronic drive, it ssynthesizes the AC current feeding the motor so that the frequency, or the synchronous speed is variable, and this is where their speed variation capability originates. The motor is also made with a copper rotor, which makes the motor more efficient, copper resistivity is less than that of aluminum.
