Not very far at all. Very little power is needed to get wheels to spin in air at 100mph. When touching down, there would be a lot of wheel “spinout”. I’d expect well under 50 feet.
MythBusters did a similar segment as part of “hit the ground running:” https://mythresults.com/end-with-a-bang
There are still some variables you haven’t mentioned. How high in the air are you talking, and will the car be dropped, or gently lowered? What kind of terrain is it? A flat, paved surface would be different than a field with rocks and bushes.
I seem to remember a toy car that kids could rev and set down, and it zoomed across the floor very well. A small plastic car isn’t the same as a real one, though.
Ok a car just above the ground maybe a foot or so. The car will be dropped after hitting 100mph. It will be on asphalt in a straight line. It is a flat surface.
