Tesla Roadster Electric Sports Car

The first electric car manufactured by Tesla Motors, the high-performance, zero-emissions Tesla Roadster sports car, was unveiled before a crowd of car buffs and potential customers.

Tesla Roadster front

The electric Tesla Roadster has the equivalent of 135 mpg and a range of 250 miles on a single charge, a combination unseen until now in a mass-produced electric car. Its extended range is due to its state-of-the-art lithium-ion Energy Storage System.
The Tesla Roadster is capable of accelerating from 0-60 mph in four seconds.

Tesla Roadster side

Using a unique two-speed electrically activated manual transmission, the Tesla Roadster's power comes from a 3-phase, 4-pole AC induction motor. The motor is controlled by the Power Electronics Module (PEM) which also controls the inverting direct current to 3-phase alternating current, charging and braking systems.

Tesla Motors's engineers have gone to great lengths to ensure that not only is the Tesla Roadster safe to drive, but also is safe when charging, at home or on the road.

The electric motor's efficiency rating is likely to be as high as 95 percent, while the internal combustion engine's efficiency is 20 percent or less. With this efficiency, the Tesla Roadster achieves the equivalent of 135 mpg.

That efficiency doesn't slow this sleek sports car down, either. Estimated 0-60 mph time is around four seconds, and with an electric motor, the torque is instantaneous, throw-you-back-in-the-seat responsive.

All in all, this is remarkable sports car!
