Motors integrated the battery pack into the floor of the vehicle, contrasting the Roadster, which had the battery pack behind the seats. Since the battery is integrated into the floor of the Model S, no interior space is lost for batteries, unlike in other electric vehicles, which often loses space for batteries. The battery’s location allows for quick battery swapping (about 90 seconds). Tesla Motors' first production vehicle, the Tesla Roadster, was an allelectric sports car, as well as the first production automobile to use lithiumion battery cells and the first production BEV to travel more than 200 miles (320 km) per charge. The car’s average range was 245 miles (394 km) per charge.
The Tesla Roadster was given "Best Inventions 2006—Transportation Invention" award in Time in
December 2006. The first set of fully equipped Roadsters sold out in less than three weeks with the second hundred selling out by October 2007. In January 2010, Tesla began producing its first righthanddrive Roadsters for the UK and Ireland, later selling them in mid2010 to Japan, Singapore,
Hong Kong and Australia. Tesla stopped producing the Roadster in the U.S. market in August 2011 when its supply of Lotus Elise gliders ran out, as its contract with Lotus Cars for 2,500 gliders expired
at the end of 2011. The next generation of Roadsters are expected to be introduced in 2014, based on a shortened version of the platform developed for the Tesla Model S. The Tesla Model S was the top selling new car in Norway in September 2013, thus becoming the first electric car to top the sales ranking in any country. The Model S captured a market share of
5.1% of all new car sales that month. In December 2013, the Model S once again topped the best selling new car list in Norway. In March 2014, the Tesla Model S became the top selling car for one month ever in Norway. Studies showed that 10.8% of all new cars registered in Norway in March 2014 were Tesla Model S. In the American market about 18,000 units
