Tesla Roadster Thruster Teardown: SpaceX COPV Tank Plus Optimus Actuator
XFreeze · x · 2026-10-16
XFreeze breaks down the cold-gas thruster system of the new Tesla Roadster, with nearly every part sourced from elsewhere in Musk's empire:
- A 200-liter carbon overwrap pressure vessel (COPV) built on SpaceX tank tech sits where the trunk would be, storing nitrogen at up to 10,000 PSI
- The valve actuator is borrowed from Optimus, snapping open with robot-level precision
- Equal-length pipes ensure all four rear nozzles fire at identical pressure for balanced thrust
- Compressed nitrogen alone delivers sub-1-second 0-60 mph, no fuel burned
Engineers targeted roughly fighter-jet thrust; one quote: "That's not Tesla."
