Tesla Plans to Open Source Model S and Model X Designs and Software
The move follows Tesla's similar open-source release of original Roadster materials in November 2023.
Tesla CEO Elon Musk announced that the company plans to make the design and software of its Model S and Model X fully open source, extending an approach it first took with the original Roadster.
What Happened
Musk confirmed on social media that Tesla will release the designs, engineering documentation, and diagnostic materials for both flagship models. This follows the company's earlier open-source commitment to the original Roadster in November 2023, when Musk stated 'whatever we have, you now have.' The Model S debuted in 2012 as Tesla's first mass-produced vehicle—a luxury electric sedan known for its range and rapid acceleration. The Model X followed in 2015 as a high-performance SUV featuring falcon-wing doors. Production of both models concluded in the second quarter of 2026, with custom orders closed and only remaining inventory available before the announcement.
Why It Matters
For existing Model S and Model X owners, the open-source release means better access to technical documentation, diagnostic tools, and software resources—potentially making independent repairs and modifications more affordable. Independent repair shops gain a pathway to support these aging but capable vehicles without relying solely on Tesla's service network. Enthusiasts and engineers can study real-world implementations of Tesla's battery, powertrain, and software systems, which could accelerate broader industry progress in electric mobility. The move aligns with Tesla's 2014 patent pledge and its stated mission to advance sustainable transport by sharing hard-won knowledge rather than keeping it proprietary.
The Bottom Line
With Model S and Model X production ended, open-sourcing these materials ensures continued support for early adopters while freeing internal resources for future technologies like Optimus humanoid robots and the Cybercab autonomous vehicle. Tesla's original Roadster open-source release already enabled simulations and community projects; extending this practice to its flagship sedans and SUVs should deliver similar benefits on a larger scale.
