For an all-electric car, the Tesla Roadster speed numbers are very impressive. The Roadster is reported to have a maximum range of 244 miles on a single charge. The three phase, four pole motor on the newer models delivers a very impressive 288 horsepower. The torque delivered by the motor is constant from 0 to 14,000 RPM at 200 foot pounds. The car is electronically limited to a maximum speed of 125 miles per hour. However, if the speed limiter was removed, the car could achieve much higher speeds. In testing, the Tesla tripped the quarter mile in 12.6 seconds at just over 100 miles per hour.
