Musk framed the decision as driven by “autonomy,” and said the Fremont factory production line currently used for Model S and Model X will be replaced with a production line for Tesla’s planned humanoid robot, Optimus. Musk announced that Model S and X are being mothballed. The same update included a $5,000 price increase, taking the Model S to $84,990 and the Model X to $89,990. Model S launched in 2012 and Model X in 2015, with a notable interior refresh in 2021 that added the yoke steering wheel. Electrek also stated that Lucid Air has surpassed Model S and Rivian R1S outcompetes Model X.
