Tesla Completes Retirement of Oldest Model S/X Assembly Line in 46 Days
Tesla completed the dismantling of the earliest Model S and Model X assembly line at the Fremont factory in 46 days. This line was one of Tesla's longest-running production lines and is now officially retired.
The Model S began production in 2012 and the Model X in 2015, with a total of approximately 610,000 units produced, and the last batch of vehicles rolled off the line in early May.
Market Mechanism: Tesla is dismantling the low-volume flagship vehicle production line to free up space for the mass production of the third-generation Optimus humanoid robot. Under this event-driven approach, funds and capacity are shifting towards the robotics business, benefiting Tesla's future growth in high-potential areas while traditional automotive production lines face resource pressure.

Tesla announced a gradual phase-out of Model S/X by the end of 2025, with Elon Musk referring to it as an "honorable discharge". Following this, the Fremont factory quickly pivoted to new business, and the 46-day dismantling efficiency reflects its execution capability, continuing the transition from automotive to robotics/AI hardware.
In terms of capital strategy, Tesla is reallocating resources at the Fremont site to restructure production lines, utilizing an almost entirely new supply chain for Optimus. The motivation is to seize the first-mover advantage in the humanoid robot market, supporting an annual production target of one million units through internal capacity optimization and reducing reliance on the automotive business.
Similar to the early shift to large-scale production of Model 3/Y, this move positions Tesla in the expansion phase of robot mass production, transitioning from a leader in electric vehicles to a leader in embodied intelligence.
Structural Judgment: Essentially, this is a restructuring of the industrial chain. Automotive manufacturing experience is spilling over into robot production, with the mechanism being that as AI and automation technologies mature, factory space and engineering capabilities migrate from low-growth mature models to high-potential new categories, achieving optimal resource allocation.

- The faster the old line is dismantled, the sooner the new business can start.
- Capacity is not about conservatism, but making way for higher leverage opportunities.
- Corporate transformation is like restructuring production lines: dismantling the existing stock is necessary to create new growth.
