Tesla Roadster



The Tesla Roadster is an all-electric sports car produced by the electric car firm Tesla Motors and is the first car produced by the company.

The Roadster can travel 244 miles (393 km) on a single charge of its lithium-ion battery pack, and can accelerate from 0–60 mph (0–97 km/h) in 3.9 seconds. An improved, Sport version of the Roadster has been released with adjustable dampers and a new hand-wound motor, capable of 0–60 mph (0–97 km/h) in 3.7 seconds. The Roadster's efficiency, as of September 2008[update], was reported as 120 mpgge (2.0 L/100 km). It uses 135 W·h/km (4.60 mi/kW·h), battery-to-wheel, and has an efficiency of 90% on average.

The Roadster was developed with design help from Lotus Cars, who supplied the basic chassis development technology from the Lotus Elise. First unveiled to the public on 19 July 2006, series production of the car began on 17 March 2008.
