The Tesla Model 3 is a battery electric powered mid-size sedan with a fastback body style built by Tesla, Inc., introduced in 2017. The vehicle is marketed as being more affordable to more people than previous models made by Tesla. The Model 3 was the world's top-selling plug-in electric car for three years, from 2018 to 2020, before the Tesla Model Y, a crossover SUV based on the Model 3 chassis, took the top spot. In June 2021, the Model 3 became the first electric car to pass global sales of 1 million.
