Tesla CEO Elon Musk took to Twitter on Sunday night to let the world know that a revised version of the company’s semi-autonomous Autopilot software would arrive on compatible cars next month.
Excited about the Tesla Autopilot software release rolling out next month. New control algorithm feels as smooth as silk.

The release will be for the most recent versions of the Model S sedan and Model X SUV, built from October 2016 onwards. Earlier Teslas—known as HW1 or “hardware 1” vehicles—used sensors and algorithms from Mobileye (like many other semi-autonomous cars).
However, following a fatal crash in May 2016 that garnered a lot of media attention, the relationship between Tesla and Mobileye broke down and the former decided to develop its own sensor suite and software. (An NHTSA investigation into the crash revealed that the car’s software was not to blame for the accident and that virtually every automatic emergency braking system would also have failed to activate given the specific circumstances of the crash.)
