Tesla Roadster Thrusters Last Seconds; Refills Take Hours
The Thrust version of Tesla's Roadster gets about five seconds of boost from its compressed-air cold thrusters. Lars Moravy, Tesla's vice president of vehicle engineering, told Top Gear that filling the Thrust's 200-liter tank from an external high-pressure nitrogen supply takes two to six hours. Tesla says the Roadster can refill its own compressed-air tanks, but has not disclosed how long that takes. The invite-only Rocket version gets 10 thrusters and a 400-liter pressure vessel that replaces the passenger seat.…
- The Thrust offers about five seconds of boost from four rear-facing thrusters.
- Filling the 200-liter tank takes two to six hours, according to Lars Moravy.
🔎 Why it matters: Tesla has not yet explained how the Thrust's tanks are refilled. Moravy describes a two-to-six-hour external nitrogen fill, while Musk talks about refilling with the car's own air.
📈 Upside: The suction fans run on battery power and do not depend on the tanks, so the added grip does not disappear when the compressed air runs low.
📉 Risk: If refilling depends on the two-to-six-hour external nitrogen fill, the Thrust would be without thruster boost for hours after each use.
