Last updated: October 17, 2026. Tesla hasn’t announced a price or final specs, so we’ll update this page when that changes.
Tesla finally showed its next-generation Roadster on Thursday. Most of the headlines are about the stunts: the car jumping, twisting in the air, and landing softly.
Under the show is a real engineering question. How does a road car use rocket-style thrusters to do that? And how much of it is something you could actually buy?
Here’s the tech in plain English, what Tesla is claiming, and what’s still missing.
The quick version
- The Roadster uses cold-gas thrusters, not rocket engines. They push out compressed gas to create force.
- Tesla says the system was developed with SpaceX and needed new hardware and controls to work in the atmosphere instead of in a vacuum. electrek
- Only the top trims have the thrusters, and Tesla’s own page says the Rocket version isn’t approved for public roads. electrek
- There’s still no price, and the only production date is 2028. electrek
What is a cold-gas thruster?
Forget fire and explosions for a moment. A cold-gas thruster is a tank of compressed gas with a nozzle. Open a valve, and the gas rushes out one way. The thruster, and whatever it’s attached to, gets pushed the other way. It’s the same physics as letting go of an inflated balloon.
“Cold” means there’s no combustion. That makes the system simple and precise, which is why spacecraft use it for small orientation changes. It’s also why it’s weaker than a real rocket engine, because burning fuel releases much more energy than just releasing gas.
For a car, the trade-off is clear. You get quick, controllable bursts of force, but the gas runs out fast. That explains why the demo moves were short hops and flips instead of anything like flying.
How the Roadster stores the gas
The thrusters are only as good as the gas supply. Tesla says it packed carbon-fiber-wrapped pressure tanks into every spare space in the car to hold the compressed gas, and that more gas means more airtime. electrek
That’s an important detail. It shows the thrusters are a space-and-weight problem as much as a power problem. Every tank takes room away from something else.
Why thrusters could make it so quick
Normally, a car’s acceleration is limited by its tires. The tires can only transfer so much force to the road before they slip.
Thrusters push on the car directly, so they bypass that limit. Tesla claims the force is four to five times what the tires can handle. If that’s true, it explains the huge acceleration numbers. We’ll need independent tests to confirm it. electrek
The other trick: suction
The thrusters get the attention, but the Roadster has a second system that works the opposite way. Tesla says fans pull air from under the car, enough to hold it upside down even when it’s stationary. electrek
The idea isn’t new. Racing engineers have used fans to create downforce before, in cars like the Chaparral 2J and the Brabham BT46B. Both were eventually banned or withdrawn. What’s new here is putting it in a road-focused electric car.
In Track Mode, the car lowers itself and uses active wings driven by the same type of actuators Tesla developed for its Optimus robot, with downforce Tesla says approaches F1 levels. Again, that’s Tesla’s claim. electrek
The three Roadster trims
Tesla revealed three versions after the event: electrek
| Trim | Who it’s for | Key features | Claimed 0-60 mph |
|---|---|---|---|
| Performance | Road-ready, 2 seats | Active aero, multi-mode suction system | Under 1.6 sec |
| Thrust | Race-ready, 2 seats, limited release | Adds rear-mounted cold-gas thrusters | Under 0.9 sec |
| Rocket | 1 seat, invite only | Thrusters around the car, 230+ mph top speed | Under 0.59 sec |
Tesla also quotes a range of over 300 miles. All of these numbers come from Tesla, not from independent testing. electrek
What changed since 2017
Tesla first showed this car back in 2017. At that time it promised production in 2020, 620 miles of range, a top speed above 250 mph, and four seats. The current version is quoted at about half the range and offers two seats at most. electrek
Acceleration went the other direction. The base Performance trim is quicker than the 1.9-second time promised in 2017.
So, is it a flying car?
No. The demo showed the car launching off a ramp, clearing five other Teslas, and landing softly with its thrusters. That’s a controlled jump, not sustained flight, and the limited gas supply is the main reason. NBC News
Some analysts see it mostly as a showpiece. One Tesla investor called it an engineering flex that does little commercially, and said it shows why Musk wants Tesla and SpaceX closer together. That’s one opinion, but it’s a fair question: will the thrusters ever matter to regular buyers?
What we still don’t know
- Price: none announced for any trim
- Real-world performance: no independent testing yet
- Production date: Musk says 2028, and this car has missed every earlier date
- Legal status: Tesla’s page says the Rocket trim isn’t approved for public roads, and it’s unclear how the thruster and suction systems would be certified
- Reservations: Tesla reopened them, with $5,000 due upfront, described as refundable, and $45,000 more within 10 days. Think carefully before putting down a large deposit on a car with no price. electrek
FAQ
Does the Tesla Roadster really fly?
No. It makes short, controlled jumps using cold-gas thrusters. It isn’t designed for sustained flight.
What’s the difference between cold-gas thrusters and a rocket engine?
Cold-gas thrusters release stored compressed gas. Rocket engines burn fuel. The first is simpler and more precise, the second is far more powerful.
When will the Tesla Roadster be released?
Musk said production wouldn’t start until 2028, and no price has been announced. CNBC
Can you drive the thruster version on public roads?
Not at the moment. Tesla’s own page says the Rocket trim isn’t approved for public road use. electrek
Who built the thrusters?
Tesla describes the Roadster as a collaboration with SpaceX.
Final thoughts
The Roadster’s tech is real engineering, even if some of it is more spectacle than product. Cold-gas thrusters, suction fans, and active wings in one car is a bold combination.
The gap is between the demo and the car you could actually buy. Until there’s a price, independent testing, and a production date, treat the big numbers as promises. We’ll keep this article updated as Tesla shares more.
