Musk cautioned that initial production will be slow due to the complexity of the new line, which includes 10,000 unique parts. The transition from the Model S/X line to Optimus production is set to occur rapidly, with the dismantling of the existing line starting next month after 14 years of Model S and 11 years of Model X production."

# Tesla confirms Optimus production starting late July at Fremont on former Model S/X line

During Tesla’s Q1 2026 earnings call today, CEO Elon Musk confirmed that Optimus robot production will begin at Fremont in late July or August — just four months after the last Model S and X roll off the line in early May.

Musk warned, however, that initial output will be “quite slow,” calling it “literally impossible to predict” the production rate this year given Optimus has 10,000 unique parts across an entirely new production line.

## Converting the Model S/X line in record time

The timeline Musk laid out is aggressive. The last Model S and X vehicles will be produced in early May, ending a 14-year production run for the Model S and 11 years for the Model X. Combined, Tesla produced over 610,000 of these vehicles — but sales had dwindled to roughly 30,000 annually, a fraction of the line’s 100,000-unit capacity.

Once the final vehicles are assembled, Tesla will dismantle the entire production line from the ground up — starting with smaller parts production equipment and working forward to final assembly, which Musk said will be torn down next month.
