The Tesla Model S is an all-electric five-door liftback sedan, produced by Tesla, Inc., and introduced on June 22, 2012. Model S vehicles built after October 2016 have the option of an advanced driver assistance system that allows the car to operate without assistance from the driver, but the driver must supervise continuously and take control if there is an issue. This feature is called Autopilot. Sentry mode is available on Autopilot hardware 2+, built after August 2017. Sentry Mode senses and records suspicious activity around the car. Autopilot 2.0 also includes Enhanced Summon, which allows the car to drive through a parking lot to find you, without anybody in the driver's seat. In 2013, the Model S became the first electric car to top the monthly new-car-sales ranking in any country, twice leading in Norway, in September and December 2013 In 2019, the US magazine Motor Trend named the 2013 Tesla the ultimate car of the year over the magazine's 70-year history.
