Tesla Dismantles Model S and X Lines for Optimus

Tesla decommissioned the original Model S and Model X assembly line at its Fremont Factory in 46 days, clearing space for high-volume production of the Optimus humanoid robot. The decision followed CEO Elon Musk's announcement during the Q4 2025 Earnings Call that production would wind down by the end of Q2 2026. Optimus Gen 3 production is already underway at Fremont, with full-scale output expected in late July or August.
