How Tesla's Roadster Drives Upside Down and Flies (and What Is Still Unproven)

At its Oct 15, 2026 reveal, Tesla showed a Roadster driving up a steep ramp, holding itself upside down, and hopping over a row of cars with the help of air thrusters. No magic. Two ideas do the work: suction and thrust. This post explains both, and marks which facts come from Tesla and which only come from news reports.

Trick one: suction

What Tesla says. On its Roadster page, Tesla describes a "multi-mode fan and ground sealing system" that acts as a downforce generator, "pulling air out from beneath the vehicle." It adds that this gives "enough suction to hold the vehicle upside down, even when stationary." (Source: tesla.com/roadster)

The physics, in plain words. This part is general physics, not a Tesla claim. The air around us pushes on everything. If fans pull air out of the gap under the car and skirts seal that gap, the pressure underneath drops. The higher pressure outside then pushes the car against the surface. Think of a vacuum cleaner pressed to a floor, or a suction cup.

What outlets report. Electrek describes a multi-mode suction system that creates a low-pressure zone under the car using skirts. Road & Track reports that in the demo the car drove up a vertical ramp, stopped upside down, came back, then went up again. (Reported by Electrek and Road & Track. We could not check it independently.)

Trick two: thrust

What Tesla says. Tesla's page says the car uses "advanced cold-gas thrusters" with "all-electric actuators" for precise thrust, making micro adjustments "within a fraction of a second" to help stabilise it in flight. (Source: tesla.com/roadster)

How a cold-gas thruster works. It is the same idea as letting go of an inflated balloon. Compressed gas is released through a nozzle. The gas goes one way, and the car is pushed the other way. "Cold" means the gas is not burned. It is just released from a tank.

What outlets report. TechCrunch quotes a Tesla engineer at the event saying the car has "10 thrusters connected to 600 liters of compressed air," and that it can be recharged. (Reported by TechCrunch, from a spoken remark at the event. We did not find this figure on Tesla's own page.) Tesla's own posts on X, as relayed by Teslanewswire, say the car's spare space holds carbon-fibre-wrapped pressure tanks, because more gas on board means more flight time. (Reported by Teslanewswire. We could not open the posts ourselves.)

The trims: only one can fly

From Tesla's own page:

• Road ready: reservation-based, two seats, active aero and suction.
• Race ready ("Thrust"): "limited release," two seats, rear cold-gas thrusters, "0-60 in under 1 second."
• Air ready ("Rocket"): "invite only," one seat, thrusters around the car for forward, upward and sideways movement. Tesla's line: "So yes, it can fly."

Tesla also notes: "Not approved for public road use," and that flight features are available on the Rocket trim only. (Source: tesla.com/roadster)

What to be careful about

• It is a stunt car, for now. The flying version is invite-only and not approved for public roads (Tesla's page). Elon Musk said production is planned for 2028, with no price given (reported by TechCrunch).
• The 0-60 number comes from demos and claims. Road & Track reports 0.81 s on the demo timing. Tesla's page says "under 1 second" for Thrust. Electrek lists different per-trim claims, including under 0.59 s for Rocket. These are Tesla's claims, not independent tests.
• Not everyone is convinced. Electrek's technical analysis says some downforce figures look unrealistic and "some liberties may have been taken," and treats the demo as real only for the sake of discussion. We are not saying the demo is fake. We are saying the numbers have not been independently checked.
• "Flying" here means short, controlled hops, not a flying car you can commute in. Wired has run a piece on the FAA angle (see sources).

What we left out, and why

These numbers circulate online but we could not trace them to Tesla or to two credible outlets, so we did not use them: "2 g of grip", "250 kg of air", "two tanks", and a claim about fog from the nozzles. Some outlets also mention nitrogen and extra nozzles (MotorTrend). We have not confirmed this with Tesla.

The short version

Fans pull air from under the car, so the air outside pins it to the surface. Nozzles fire compressed air, so the car is pushed the other way. Tesla's own page confirms the suction idea, the cold-gas thrusters, the trims and the "not approved for public road use" note. Figures like 10 thrusters, 600 L and 0-60 timings are reported, not independently checked.
