The Tesla Roadster combines the performance of a high-end sports car — it can accelerate from zero to 60 mph in 3.9 seconds, according to the automaker — with the environmental-friendliness of an all-electric drivetrain that emits zero emissions.
Built in limited numbers, the Roadster can travel nearly 250 miles on a charge, and its lithium-ion battery pack can recharge in 3.5 hours. A Sport version features quicker acceleration and an adjustable suspension. Competitors to the Roadster include the Porsche 911 and Audi R8.
What's changed for 2010
All Roadsters have a restyled interior with relocated center controls, new push-button transmission controls and a relocated vehicle information display. The Roadster Sport has a hunkered-down suspension and additional engine torque, which cuts zero-to-60-mph acceleration to 3.7 seconds.
The Roadster is about the size of a Lotus Elise, and Lotus builds the Roadster's chassis for Tesla. The Roadster has its own styling, but because the proportions of the cars are similar, it still brings to mind the Elise. The Roadster's body is made of carbon fiber.

The Roadster's cabin has a minimalist design, though its cabin looks slightly more conventional for 2010.

Under the Hood
The rear-wheel-drive Roadster is powered by an air-cooled electric motor that makes 288 horsepower and 273 pounds-feet of torque in base Roadster versions versus 295 pounds-feet of torque in Sport versions. Peak torque is available from 0 rpm, which is a boon for acceleration. The electric motor drives the wheels through a fixed gear, and the motor can function as a generator when decelerating to help recharge the battery pack. The electric motor is powered by a lithium-ion battery pack made up of 6,831 cells. The battery pack weighs nearly 1,000 pounds, and Tesla says it should last for five years or 100,000 miles.
