Tesla Fremont Model S Model X Assembly Line Replaced by Optimus Production

Tesla Inc has officially marked the end of a significant chapter in its manufacturing history by dismantling the original production line used for the Model S and Model X at its Fremont facility in United States. On July 10, the company's manufacturing team released a video documenting the extensive teardown process, describing the milestone with the words "End of an era." The footage highlighted the transition from one of Tesla's longest-running vehicle assembly lines toward a new manufacturing strategy focused on humanoid robotics.

Tesla Removes Historic Fremont Production Line

The dismantling project was completed in only 46 days. During this process, engineers removed robotic arms, conveyor systems and other production equipment before using heavy construction machinery to demolish infrastructure and fill the concrete pits that had supported the assembly line. Once the area was fully cleared, the available factory space became ready for the installation of a new production system dedicated to Optimus humanoid robots.

Model S and Model X Production Timeline

Production of the Model S and Model X at the Fremont facility concluded with a special signature delivery ceremony held on May 20. Earlier in April, Tesla had already stopped accepting custom orders for both models, while the final vehicles were manufactured during early May. The Model S originally entered production in 2012 and became one of the company's most recognizable electric vehicles throughout its production history.

Key Milestones in the Fremont Manufacturing Transition

Factory Transition Supports Optimus Expansion

Chief Executive Officer Elon Musk had previously stated that the existing Model S and Model X production line at Fremont would eventually be replaced by a dedicated manufacturing system for Optimus humanoid robots. According to the company's stated objective, the future production line is expected to target an annual manufacturing capacity of one million humanoid robots, representing a major shift in the long-term use of the Fremont facility and its manufacturing resources.
