Overview
- Elon Musk tweeted on July 24 that Tesla plans to make the Model S and Model X designs and software open source, a public promise that has not yet been followed by a formal file release or license.
- Tesla ended Model S and Model X production earlier in 2026 and halted assembly at its Fremont plant in late March 2026 as the factory space is reallocated to projects such as the Optimus robot.
- Analysts note Tesla’s November 2023 Roadster disclosure offered only a small set of CAN database files, a diagnostic ISO, and manufacturing outputs behind a login rather than original CAD or firmware source, so a similar S/X package would be mainly documentation.
- Engineering contractors who examined the Roadster files found Gerber and pick‑and‑place outputs instead of PCB source files, which forced them to reconstruct component footprints and limited the materials’ direct reuse.
- If Tesla supplies complete CAD, firmware source and a permissive license the release would help owners and independent repair shops maintain older cars and give engineers a real reference design; if it repeats the Roadster pattern the practical benefits will be narrower.
