It would almost certainly snap it’s driveshaft upon making contact with the ground, so maybe 15’. There are way too many variables here to come up with any kind of concrete answer, or even much of an educated guess. This would make for a fun mythbusters segment though.
Even if its tires were just 1 mm from the pavement?
Yes
The driveshaft wouldn’t be snapped from the downward force. It would be snapped because it’s happily spinning away at probably a couple of thousand rpm and then suddenly the rear tires make contact (assuming this is a RWD vehicle, otherwise it would be the CV joints breaking for the same reason) and try to get traction and move the car forward, but rubber is made to stick the surfaces and there would be an astounding amount of force applied along the drivetrain that was sped up to 100mph with no resistance suddenly trying to instantly accelerate from 0mph to 100mph with a very considerable amount of resistance.
