The Tesla Roadster is an electric powered sports car conceptualised, developed and manufactured by Tesla Motors in California, North America. It is the first production electric car to be powered with the use of lithium-ion batteries and the first entirely electric vehicle capable of travelling over 200 miles (320km) with a single full charge. The gearbox is produced in Detroit, Michigan by BorgWarner. Brakes and airbags are manufactured by Siemens in Germany as well as some crash testing. All components are finally sent to Menlo Park, California for final assembly.
