The Tesla Roadster is an all-electric sports car produced by the electric car firm Tesla Motors. The Roadster is the only highway-capable electric automobile for sale as of early 2010; all other highway-capable EVs are prototypes or evaluation series from automakers that are trying to determine whether to go forward with an electric vehicle program. The Roadster has a base price of US$109,000 and qualifies for a $7,500 US federal tax credit as well as tax credits and incentives in numerous states. The Roadster has a base price of £86,950 in the UK and €84,000 in continental Europe. The Roadster qualifies for numerous incentives throughout Europe and gets 100 percent tax waivers in several countries.
The Roadster is the first production automobile to use lithium-ion battery cells and the first production EV to travel more than 200 miles (320 km) per charge. The world distance record of 501 km (311 mi) for a production electric car on a single charge was set by a Roadster on October 27th, 2009 during the Global Green Challenge in outback Australia.
According to an independent analysis from the U.S. EPA, the Roadster can travel 244 miles (393 km) on a single charge of its lithium-ion battery pack, and can accelerate from 060 mph (097 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 (21.7 kW·h/100mi or 490 kJ/km) battery-to-wheel, and has an efficiency of 92% on average.
