First drive: Chevy Volt test - Silent power (3) - CNNMoney.com: "Up to about 30 mph, the Volt's electric motor gives quicker-than-ordinary response, which is why the car feels particularly muscular.
The Volt doesn't have a transmission, in any ordinary sense. It doesn't have 'gears' - like 'first gear,' 'second gear,' 'third gear' - because it doesn't need them. Electric motors deliver full torque even at their lowest speeds so there's no need to change gear ratios to keep the engine in a 'sweet spot' for performance.
The Volt's electric motor is sized to provide performance comparable to a 250-horsepower V6, said Posawatz, and that seemed about right."
