The company conducts business in North America, Asia and Europe. While the domestic market continues to be its most important target market, Tesla was able to successfully tap into the Chinese and European markets, as well: Norway contributed some 823 million U.S. dollars to Tesla's revenue in 2017. In terms of range, Tesla’s Model S remained the cream of the crop in 2018, and it is little surprising that the Model S was the best-selling all-electric car in the United States in 2017.
Tesla also has its own powertrain segment, and Toyota’s RAV4 electric vehicle is equipped with a Tesla-produced battery and electric powertrain. In July 2014, Tesla and Panasonic announced to participate in the construction and operation of the world's largest battery factory in the United States. Furthermore, the company is heavily involved in the development of driverless cars. However, Tesla’s autopilot technology has come under scrutiny after a failure caused a fatal accident in 2016.
