Unlike other hybrid cars, such as the Toyota Prius, the Volt's gasoline engine would never power the car's wheels. Instead, it would recharge the car's batteries if needed while the car would continue to run on electric power alone.
The Volt's electric motor can produce up to 121 kilowatts, the equivalent of about 161 horsepower. It can produce 320 newton-meters, or about 236 foot-pounds, of torque. Electric motors offer more torque - the pulling power a car uses to accelerate - relative to their kilowatt or horsepower output than gasoline engines do.
