Tesla's Original Roadster Design and Engineering Is Now 'Fully Open Source'

Tesla open sources design and engineering information for the original Roadster

Alexandre Prévot

Tesla's incredible journey started by piecing together the Roadster, a painstaking ordeal that nearly caused the company to go bankrupt more than once. The piece-by-piece instruction manual to build the car that started an automotive revolution has been made public, fully open-sourced. CEO Elon Musk posted on X: "All design & engineering of the original @Tesla Roadster is now fully open source. Whatever we have, you now have."

Community Engagement and Possibilities

The open-source announcement has sparked enthusiasm and curiosity within the engineering community. A post from the World of Engineering (@engineers_feed) on X, asking, "Does this mean I can build my own roadster in my garage?" garnered a direct response from Musk: "* some assembly required."

Theoretically, if one can get their hands on the parts, they have some direction to build one of these historic vehicles. From a business side, this kind of information sharing with competitors is curious, although it does follow Tesla's mission statement to accelerate the world's transition to sustainable energy. Although the information is 15 years old, it could provide some useful information.

Understanding the Open-Source Details

Tesla has clarified the nature of the information released, stating it's a resource for Roadster enthusiasts derived from the car's R&D phase. The details are not intended for manufacturing, repair, or maintenance and may not align with final production models. Users leveraging this information are reminded of their responsibility to adhere to legal and safety protocols, as Tesla offers no warranties for work done using these details. This open-source initiative encourages innovation but stresses the importance of safety and legal compliance.

The Roadster's History and the Future

Launched in 2008, the original Roadster was the first legal electric vehicle on highways to utilize lithium-ion batteries and achieve over 200 miles per charge. It bankrolled the next phase of Tesla, the Model S, and set a benchmark for future EVs.

While this open-source initiative revisits Tesla's past, it also shifts the focus back to the next-generation Roadster. Initially unveiled in 2017, its production has been delayed, and there is no timeline for when the new sportscars will be manufactured. Moreover, Tesla's focus on the Cybertruck and a more affordable $25,000 EV indicates a strategic balance between innovation and mass EV adoption.

Tesla's decision to make the original Roadster's design and engineering open source should not be too surprising. Musk has said, "I don't care about patents. Patents are for the weak. They don't actually help advance things. They just stop others from following you." Perhaps the biggest surprise is how long it took for Musk to open-source the Roadster blueprint.

Tesla Says 12V Power Socket Access Will Not Return With Sentry Mode

Not a Tesla App

It turns out that the big undocumented change in Tesla update 2024.32 that disables the 12V power and USB ports while Sentry Mode is active is not a bug but an intentional change.

A fan contacted Tesla Service to see if the change was intentional and what the reason behind the change was. Surprisingly, they received a response pretty quickly.

No 12V Power Access

Tesla has decided to restrict 12V power access for safety reasons—namely, to “reduce the likelihood of thermal events” when third-party devices are left powered on without users present. Tesla reached out to the fan in question by phone, and they seemed to be sticking to that line.

It seems that Tesla is resolute that it was due to safety reasons and that the change would not be “fixed” or allowed in a future software update – as this was an intentional change for safety reasons.

Other sources have reported that the change was due to potential misuse of the 12V power access, with people wiring 1200w microwaves and kettles or jury-rigging 240v to 120v adapters, which had apparently been the cause of multiple fires in Tesla vehicles within China.

Workarounds

There are a couple workarounds, although neither are ideal. You can tap in to the vehicle’s 12v line directly to power your accessories, or you can use Camp Mode.

If you choose to enable Camp Mode, then you’ll need to manually lock the car from the app since walk-away door locking is disabled with Camp Mode. However, Camp Mode will use extra energy to keep the climate system enabled.

We’re still hoping Tesla considers bringing the Cybertruck’s Power Control menu to the rest of its vehicles and is somehow able to limit the max draw from these outlets to prevent dangerous situations.
