Tesla Rapidly Tears Down Model S and X Lines at Fremont Factory, Paving the Way for Optimus Production

The decommissioning of Tesla’s original Model S and Model X assembly line at its Fremont factory in Northern California has been completed in just 46 days. The teardown involved heavy machinery dismantling concrete pits, removing robotic arms and conveyors, and clearing the space for new production. This rapid process marks a significant step towards repurposing the valuable factory floor space for high-volume production of Tesla’s Optimus humanoid robot.

The decision to retire the Model S and Model X originated during Tesla’s Q4 2025 Earnings Call in late January 2026, where CEO Elon Musk announced that production of these vehicles would wind down by the end of Q2 2026. He described it as bringing the programs to an ‘honorable discharge.’ Custom orders ceased around early April 2026, with the final vehicles rolling off the line in early May.

A special signature delivery ceremony on May 20 marked the emotional close for these vehicles, which had defined Tesla’s early success and luxury EV segment since the Model S launch in 2012. The primary reason for tearing down the lines was to repurpose the valuable factory floor space for high-volume production of Optimus, a crucial step towards Tesla’s broader strategic shift from traditional vehicle manufacturing toward robotics and artificial intelligence.

Tesla is targeting rapid scaling with internal ambitions pointing toward tens or even hundreds of thousands of units annually by the end of 2026. Longer-term, the company is constructing a much larger second-generation Optimus facility at Giga Texas, with potential capacity reaching millions of units per year. The goal is to make Optimus a transformative product that could eventually surpass Tesla’s automotive business in scale and value.

Optimus, designed by Tesla, is a general-purpose humanoid robot aimed at performing repetitive or dangerous tasks in factories, warehouses, and eventually homes. Powered by Tesla’s AI and Neural Networks, it aims to be a versatile, affordable platform for various industries. Production of Optimus Gen 3 is already underway in limited form at Fremont, with full-scale output on the converted line expected to begin in late July or August.

Tesla’s aggressive pivot towards its next major initiative, Optimus, marks a significant shift in focus from traditional vehicle manufacturing. The company views this move as crucial for leveraging its expertise in autonomy, AI training, and high-volume production. As one era closes at Fremont, another is rapidly taking shape with the potential to revolutionize industries beyond automotive.

Tesla’s CEO Elon Musk has been vocal about his vision for a future where robots like Optimus play a significant role in various sectors. He believes that by making these technologies accessible and affordable, Tesla can drive widespread adoption and create new opportunities for businesses and individuals alike.

The decommissioning of the Model S and X lines is just one aspect of Tesla’s broader strategy to transform its operations and focus on emerging technologies like robotics and AI. As the company continues to push boundaries in innovation, it remains to be seen how this shift will impact the automotive industry as a whole.
