Tesla recently updated the over-the-air software to the 2019.36.2.1 version with a 5% increase of power to the owners of the Model 3, Model S, and Model X.
Jenny Walsh, a YouTuber, made a video where she and her friend, both owners of Model 3, tested the differences before and after the improvement. They updated only one of the cars, and the difference was surprising. The new software version, with the power update, made this car lead the drag race of about a car length during the tests.
Tesla optimized for motor control, which increased both range and power delivery for all cars in the fleet. The software can update the vehicle regularly, improving the machinery without changing anything, giving the owners the change to experience the new features frequently.
