If you're @ 4k rpm on 4th doing say 100mph, you will do that irrespective of any other forces, for the rear wheels to do 100mph, your engine has to be at 4k rpm if in 4th, it's how the car's gearing has been setup. Air resistance aka drag force only affects how much TQ you'll need to get there i.e how much time I'll take you to get there, but once you're there, you will be doing 100 @ 4k rpm.

Take it easy guys I only said on the moon because I wanted to use the 0 air resistance factor, of course the cars won't move there lol
