GoKawiilTesla shows new Roadster prototype using compressed-nitrogen thrusters and 4680 cells
Tesla unveiled a new version of its long-delayed Roadster at a late-night event, featuring wedge-shaped styling and rear-mounted nozzles that fire 100,000 psi compressed nitrogen jets, reportedly to perform aerial stunts. The car uses rear-wheel drive and Tesla's own 4680 battery cells with what the company calls a special chemistry, and Elon Musk claimed a planned top speed of 383 mph and a 0-60 mph time of 0.8 seconds.
GoKawiil's interpretation of the reporting above, not reported fact.
The reliance on dramatic demonstrations rather than a production-ready vehicle echoes Tesla's 2017 Roadster reveal, which has yet to result in customer deliveries nine years later, suggesting skepticism about timelines may again be warranted. The use of compressed-nitrogen jets raises unresolved questions about regulatory approval for road use, and rivals like the McMurtry Spéirling already demonstrate superior real-world performance, which could undercut the credibility of Tesla's projected figures.
- Tesla revealed a new Roadster prototype with compressed-nitrogen exhaust jets said to enable aerial stunts.
- Musk claims a 383 mph top speed and 0.8-second 0-60 mph time, figures unverified by independent testing.
- The car uses Tesla's 4680 battery cells, which have faced prior scaling and performance issues.
