Original Tesla Roadster is Now Open-Source

The design and engineering information for the original Tesla Roadster is now available for public viewing. According to Tesla, “the information is being provided as a courtesy to Roadster enthusiasts and was created during the design phase of the Roadster for research and development.”

Elon Musk posted the update from his X account on November 22, 2023. While the documents do not display an open-source license, the material is being presented to the public using open-source methodology.

Documents released for the original Tesla Roadster include parts and service manuals, circuitry diagrams, diagnostic software, and articles about toolkits among other related information. The information also comes with a disclaimer. Tesla explicitly states that anything created from the information does not include a warranty or equate to being genuine parts. Such assurances only come from products made by official Tesla personnel.

People can now try to build and modify their own Roadster concept. Emphasis on “concept” as other required building plans, such as CAD and manufacturing specifications, have not been made available. Doubtful if this will stop enthusiasts from trying!

This is the latest open-source contribution coming from the electric automotive company. They also released their patents back in 2014. Their blog states that they “will not initiate patent lawsuits against anyone who, in good faith, wants to use our technology.” An OpenCIV spirited statement further explains their reasons.

Tesla Motors was created to accelerate the advent of sustainable transport. If we clear a path to the creation of compelling electric vehicles, but then lay intellectual property landmines behind us to inhibit others, we are acting in a manner contrary to that goal…We believe that Tesla, other companies making electric cars, and the world would all benefit from a common, rapidly-evolving technology platform.


The all electric Roadster was the first market release for the auto company. The popularity that came from the vehicle helped to pave the way for subsequent models S, X, and 3.

A new version of the Roadster is expected to be released in the near future after several years of delays. Updated features include rear seats for two people, extended range via the 200.0-kWh battery pack, and boosted performance from the three electric motors providing over 7000 lb-ft of torque.
