# Musk says Tesla to ‘open source’ Model S and X, but prior release makes us skeptical

Elon Musk says Tesla plans to “open source” the Model S and Model X, and he’s pointing to the original Roadster as the template.

The problem is Tesla’s Roadster release amounted to eight files on GitHub plus five document packages behind a login, with no open-source license attached to any of it.

## What Tesla actually put out for the Roadster

In November 2023, Musk posted that “all design & engineering of the original Tesla Roadster is now fully open source,” and added, “Whatever we have, you now have.” We covered the release at the time.

The full inventory is short. The `teslamotors/roadster` repo holds five CAN database (.dbc) files covering the Roadster 1.5 and 2.0 ESS and PEM buses, about 339 KB in total, plus a 309 MB diagnostic software ISO and two PDF quick-guides. That’s everything, aside from a README and a .gitattributes file.
