The physics behind Tesla Roadster 2's wall drive and short flight

WIRED broke down the physics behind the Tesla Roadster 2 prototype's stunts: driving up a vertical wall, hanging upside down and briefly flying. Fans lower the pressure under the car for downforce, while compressed air provides thrust for lift and sub-second acceleration, lasting only a few seconds.

• Sticking to a wall requires underbody pressure at about 86% of atmospheric
• Normal tires with a friction coefficient near 0.6 cap inclines at roughly 31°
• 0–60 mph in under a second comes from compressed-air thrust
• The air tank provides only a few seconds of thrust
