Tesla Motors was founded in 2003 by a group of engineers to prove that electric vehicles can be high-performing. It is led by Elon Musk and designs, manufactures, and sells electric cars and powertrain components. Tesla's goals are to increase electric vehicle availability through selling its own cars like the Roadster and Model S, selling powertrain components, and inspiring other automakers. It has partnerships with Mercedes-Benz and Toyota to collaborate on electric vehicles.
