Robotics Tesla Just Quietly Ended a 14-Year Model S Production Run This Week — and the Same Fremont Line Will Build a Million Optimus Humanoids a Year
In early May 2026, Tesla rolled the last Model S and Model X off the Fremont assembly line — ending a 14-year and 11-year run respectively. The same line is being torn down and reinstalled as the first-generation Optimus production line, targeted at one million humanoid robots a year. The retool window is four months. The Optimus V3 reveal lands in late July. The car factory that built California's electric-vehicle myth is now the robot factory.
