    Tesla Semi Production Update: Mass Manufacturing in 2026

    Production Milestone and Capacity: Tesla confirmed the start of high-volume manufacturing for the Semi truck in 2026 at its dedicated facility adjacent to Gigafactory Nevada. This site is engineered for a maximal annual capacity of 50,000 trucks, although the company has specified that the scaling process will be gradual. The commitment to vertical integration, particularly the co-location of the truck assembly with 4680 cell production, is intended to maintain control and insulate the manufacturing program from external supply chain volatility.

    Technical Specifications of the Long Range Model: Key specifications for the Semi Long Range version have been finalized, confirmed via filings like those submitted to the California Air Resources Board. This variant utilizes an 822 kWh battery pack, which is built using NMCA 4680 cells. This configuration supports a maximum rated range of 500 miles when the truck operates at an 82,000 lbs gross combination weight.
