Tesla has begun tearing down the original Model S and Model X assembly line at its Fremont Factory, releasing new time-lapse footage showing the decommissioning process happening in just 46 days. The space will be repurposed for Optimus humanoid robot production, with a stated goal of 1 million robots per year once fully ramped. Production of both vehicles officially wound down around May 10, 2026, after Musk announced the phase-out during Tesla's Q4 2025 earnings call in January 2026. The full conversion of the space to Optimus production lines is expected to be completed in roughly four months from start to finish. The Fremont site will host production of the third generation of Optimus, Tesla's humanoid robot. Tesla plans to begin external commercial sales of Optimus later in 2026, with a long-term price target of $20,000 to $30,000 per unit. Each Gen 3 Optimus contains roughly 10,000 unique parts. Limited production on the converted Fremont line is expected to begin in late July or August 2026.
