Ever since I was a kid wanted to ask this if I suspend a car mid air and rev it up to 100mph then drop it how far would it go without me touching the gas or break not even once?

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.
