Tesla was founded to address environmental issues through sustainable electric transportation. The company began by producing the Roadster electric sports car in 2008. Its Model S sedan launched in 2012 and became the best-selling plug-in electric car in history. Tesla's Model 3, a lower-cost electric car with a 215 mile range and $35,000 base price, began production in late 2017. While Tesla has experienced rapid growth, developing fully autonomous vehicles and increasing production remain challenging goals that introduce risk to the company's future outlook.
