Tesla’s electric-vehicle lineup includes the Model S, Model 3, Model X, and Model Y.
Tesla was incorporated in 2003 by engineers Martin Eberhard and Marc Tarpenning. Elon Musk joined as an early investor and became chairman before later serving as chief executive. The company’s first production vehicle, the Roadster, used lithium-ion battery cells and was delivered in 2008.
Tesla expanded from a low-volume sports car into mass-market vehicles. The Model S began deliveries in 2012, followed by the Model X, Model 3, and Model Y. Battery production, charging infrastructure, software, and driver-assistance features became important parts of its business identity.
Tesla is sometimes confused with traditional automakers when rankings of valuable companies are discussed. Its valuation has often reflected expectations about future electric-vehicle production, energy storage, software, and autonomy, not simply current vehicle sales.
