Tesla is an American automotive and energy company based in Palo Alto, California. The company specializes in electric car manufacturing and, through its SolarCity subsidiary, solar panel manufacturing. It operates multiple production and assembly plants, notably Gigafactory 1 near Reno, Nevada, and its main vehicle manufacturing facility at Tesla Factory in Fremont, California. As of June 2018, Tesla sells the Model S, Model X and Model 3 vehicles, Powerwall and Powerpack batteries, solar panels, solar roof tiles, and some related products. Tesla was founded in July 2003, by engineers Martin Eberhard and Marc Tarpenning, under the name Tesla Motors. The company's name was derived from physicist Nikola Tesla. In early Series A funding, Tesla Motors was joined by Elon Musk, J. B. Straubel and Ian Wright, all of whom are retrospectively allowed to call themselves co-founders of the company. Musk, who formerly served as chairman and is the current chief executive officer, said that he envisioned Tesla Motors as a technology company and independent automaker, aimed at eventually offering electric cars at prices affordable to the average consumer. Tesla Motors shortened its name to Tesla in February 2017.
