Elon Musk Says Tesla’s Next Roadster Will Feature Rocket Thrusters

Tesla CEO Elon Musk introduced in a Saturday tweet {that a} “SpaceX choice package deal” for the forthcoming Tesla Roadster will “embrace ~10 small rocket thrusters organized seamlessly across the automotive” to enhance efficiency.
Which will sound, nicely, ludicrous—and Tesla HQ has stated that as a common coverage it doesn’t affirm or deny the veracity of Musk’s tweets. However a few of Musk’s most apparently ridiculous Twitter brainstorms have wound up being completely actual, and Musk Sunday morning supplied additional technical particulars that recommend the rocket-car plan is, too.

These wouldn’t be flame-spitting jet engines burning rocket gasoline—that might, amongst different issues, nearly definitely not be road authorized. As an alternative, the thrusters can be small, extraordinarily sturdy vessels holding extremely compressed fuel. Musk stated in a tweet that the improved Roadster would use COPVs, or Composite Overwrapped Strain Vessels, that are used on the SpaceX Falcon 9 rocket for duties together with steering the rocket in house, quite than for fundamental thrust.

Musk additionally wrote Saturday that the “New Tesla Roadster will exceed all fuel sports activities vehicles in each manner.” One considerate Tesla watcher speculated in depth about simply how profoundly the usage of compressed air thrusters may change the very nature of a high-performance automotive. They may very well be used not just for acceleration, however enhanced braking utilizing forward-facing thrusters, higher street grip with upward-facing thrusters, and extremely enhanced dealing with at pace utilizing aspect thrusters. Even Musk’s remark that “possibly they are going to even permit a Tesla to fly . . .” isn’t essentially an exaggeration—the thrusters would possibly be capable of present directional help when a automotive leaves the bottom, comparable to after cresting a hill, and even let the automotive hover for brief intervals.

Notably, the failure of one among a SpaceX COPV performed a job within the Sept. 1, 2016 explosion of a Falcon 9 throughout fueling. In that case, a COPV tasked with injecting helium to take care of gasoline tank strain failed. Earlier this 12 months, an oversight panel advising NASA raised questions about the usage of COPVs for crewed missions. SpaceX has agreed to a security redesign that might presumably be prolonged to items used within the Roadster SpaceX package deal.
Musk additionally hinted that Tesla would go “quite a bit additional” than merely utilizing compressed air, with out offering specifics.

The brand new Tesla Roadster—an replace of Tesla’s first, ultra-premium sports activities automotive—was revealed in late 2017 at an occasion additionally saying the Tesla Semi. The brand new Roadster is projected to be accessible in 2020, with a base worth of $200,000. No particulars but as to how a lot the SpaceX thruster enhancements may cost a little.
