Elon’s “Flying” Roadster Stunt: Was The Ramp Magnetized?

The Tesla Roadster reveal in early 2025 looked like it broke physics. A car drove vertically up a ramp, stuck upside down at the top, then flew across the stage using cold gas thrusters. Elon Musk explained the upside-down grip as the result of a fan suction system that "really sucks" — a downforce technology that would let the car corner like nothing else. But a tech publication called The Information had reported months earlier that Tesla's plans involved a "magnetized roller coaster-like ramp." And now some skeptics are asking whether that's what actually happened — and whether Musk misled the audience to make the car look more impressive than it really is.

The Fan Suction Claim — and Why It's Hard to Believe

Musk's explanation for the ramp stunt was a fan-based downforce system. "This car really sucks," he said on stage, to laughter from the crowd. The idea is that fans under the car pull air out from beneath it, creating a low-pressure zone. The higher atmospheric pressure above the car then pushes it down — hard enough to hold it to a ceiling or a vertical ramp. Musk claimed this would give the Roadster world-beating cornering and acceleration on a track.

What you'll learn

  • 1 (00:00) **Opening Claim & Thesis** - The host states that the car "sticking" to the ramp appears to break physics, suggests the fan suction explanation is insufficient, and introduces the core question: Was the ramp magnetized?
  • 2 (01:35) **The Stunt Mechanics & Musk's Explanation** - The host describes the car driving vertically up a ramp and sticking upside down, noting it was unmanned, and plays a clip of Elon Musk explaining the fan suction system.
  • 3 (02:54) **The Precedent: McMurtry Spearling** - The host introduces the McMurtry Spearling, a hypercar that has successfully used a fan suction system to stick to ceilings for over a year, suggesting Tesla may have borrowed the concept.
  • 4 (03:36) **The Physics Problem: Ground Clearance** - The host argues that the Roadster's visible ground clearance makes a pure fan suction seal impossible, as air leakage would be too high to hold the car upside down.
  • 5 (05:09) **Context from Marques Brownlee** - The host references a video from Marques Brownlee that explains the different Roadster versions (base and fan car) and the practical physics of downforce.
  • 6 (07:03) **The Real Fan Car Performance** - The host returns to the McMurtry Spearling, showing how it drops a skirt and uses a high-RPM fan to create a vacuum, allowing it to smoke high-downforce track cars around corners.
  • 7 (08:48) **The Magnetic Track Evidence** - The host introduces the central claim from "The Information": that Tesla employees described a "magnetized roller coaster-like ramp" for the stunt.

Show Notes

John Johnston (JJ) reacts to part of a new video that suggests the spectacular Tesla Roadster “demo” may have used a magnetized ramp, not only suction from the car’s fan system, to help it up the ramp and hold upside down at the top of the ramp, before vaulting off the end. Could this be true?
