Tesla Ends Model S, Model X Production to Reallocate Fremont Capacity for Optimus Robot Manufacturing

Tesla, under the direction of CEO Elon Musk, concluded production of its foundational luxury vehicles, the Model S and Model X, in April 2026. This strategic shift involves repurposing the assembly lines at the company's Fremont factory in California to facilitate the large-scale manufacturing of the Optimus humanoid robot. The final discontinuation of custom orders for these vehicles took effect on April 1, 2026, concluding the tenure for the models that established Tesla's premium market presence since the Model S debuted in 2012 and the Model X in 2015.

The transition was formally signaled by Musk during the Q4 2025 earnings call in January 2026, where he referred to the winding down of the programs as an "honorary discharge." The Model S and Model X, which accumulated a production span of 14 years, had decreased in volume significance, accounting for less than 3% of Tesla's global deliveries in 2025. To clear remaining inventory, Tesla offered substantial lifetime benefits to final buyers, including complimentary DC fast charging and lifetime Premium Connectivity for the approximately 600 remaining units globally, comprising 295 Model S and 301 Model X units as of April 2, 2026.

This pivot aligns with Tesla's Master Plan Part IV, which emphasizes achieving "sustainable abundance" through the integration of artificial intelligence, autonomy, and physical manufacturing. Repurposing the Fremont facility is a concrete action to support the anticipated mass production of the Optimus robot, with initial phase targets at Fremont set between 50,000 to 100,000 units annually. The third generation of Optimus, designed for mass production, was slated for a Q1 2026 launch, though the public unveiling experienced a slight delay for final refinements.

Beyond the immediate factory conversion, Tesla is scaling its robotics infrastructure, having initiated construction on a dedicated Optimus manufacturing facility at Gigafactory Texas in late 2025. Musk projects an eventual annual production rate of up to one million Optimus units, suggesting the robot could eventually represent 80% of Tesla's total enterprise value. This focus on robotics signals a redefinition of Tesla from a traditional automaker, particularly as the company faces intensifying competition in the electric vehicle sector, where BYD overtook Tesla as the world's largest EV maker in January 2026.

While the discontinuation of the Model S and Model X closes a significant chapter that validated Tesla's viability in the premium EV segment, the company has committed to ongoing service, parts, and support for all existing owners of these vehicles. The total combined deliveries for the Model S and X over their lifespan exceeded 610,000 units. The conversion of the Fremont plant, the site of the first Model S delivery in 2012, represents a major strategic redirection, shifting established revenue streams toward a future centered on physical artificial intelligence and automation.
