Skepticism Surrounds Tesla's 'Open Source' Claim for Model S and X

Elon Musk, Tesla's CEO, has declared the company's intention to release the design specifications for its Model S and Model X vehicles in an 'open source' format, drawing parallels to the previous disclosure made for the original Roadster. However, this announcement has been met with considerable doubt, stemming from the perceived inadequacy of the Roadster's prior 'open source' offering. The earlier release for the Roadster comprised only a handful of files hosted on GitHub and several document packages accessible through a restricted login portal, notably without any recognized open-source licensing. This previous effort has led to a cautious reception of Musk's latest pledge regarding the Model S and Model X.
The Ambiguity of Tesla's 'Open Source' Commitment
Tesla's initial venture into 'open source' with the Roadster in November 2023 was heralded by Musk as a complete disclosure of its design and engineering. However, a closer examination revealed this release to be quite limited. The publicly accessible repository contained only a few CAN database files, a diagnostic software ISO, and a couple of quick-guide PDFs. Crucially, it lacked core design elements like CAD files, mechanical schematics, bill of materials, and source code for essential components, such as the Power Electronics Module or motor designs. Furthermore, the accompanying 'license' was merely a liability disclaimer, offering no rights for users to copy, modify, or redistribute the material, thus failing to meet the accepted criteria for genuine open-source initiatives.
This precedent casts a long shadow over the recent promise to 'open source' the Model S and X, especially given that production for these models concluded in April. If Tesla adheres to the same playbook, the release would likely consist of similar diagnostic software, some CAN databases, and manufacturing output files for minor components, rather than comprehensive design and engineering data. Industry experts note that while any data release is beneficial, the absence of crucial elements like firmware source and proper open licenses undermines the spirit of open sourcing. A truly impactful open-source release for the Model S and X would entail providing full documentation, including CAD and source code, under a recognized open license, thereby offering invaluable insights to the automotive industry.
Evaluating the Impact and Potential of Future Releases
Despite its shortcomings, the information released for the Roadster did prove useful for independent repair shops and engineers, enabling them to maintain older vehicles and even develop simulations of the car's electronics. This level of transparency, though limited, is uncommon among major automakers, earning Tesla some credit for its willingness to share. However, critics argue that labeling this as 'open source' is misleading, as the fundamental principles of open-source—specifically, the granting of usage rights through a clear license—were not upheld. Musk's previous assertion of a complete disclosure of everything Tesla possessed was not fully accurate, as significant design and firmware data remained proprietary.
The skepticism surrounding the Model S and X announcement is therefore well-founded. While a genuine, comprehensive open-source release for these vehicles—which represent a decade and a half of electric vehicle platform development—would be an unprecedented contribution to the industry, the likelihood of this occurring seems low given past performance. Such a release, including detailed CAD files, firmware source code, and full GPL compliance, would offer unparalleled educational and developmental opportunities for engineers and manufacturers. Without these critical components and a proper open license, any future release for the Model S and X would likely be perceived as a mere documentation dump, similar to the Roadster's, rather than a significant step towards true open innovation.
