The Tesla Roadster delivers full availability of performance every moment you are in the car, even while at a stoplight. Its peak torque begins at 0 rpm and stays powerful at 13,000 rpm.

This is the precise opposite of what you experience with a gasoline engine, which has very little torque at a low rpm and only reaches peak torque in a narrow rpm range. This forces you to make frequent gear changes to maintain optimal torque. With the Tesla Roadster, you get great acceleration and the highest energy efficiency at the same time. All while requiring no special driving skills to enjoy it. This makes the Tesla Roadster six times as efficient as the best sports cars while producing one-tenth of the pollution.
