I have to say I was skeptical - but my maths and physics background says - YES. Here is the logic:
1) If you know the weight of the car - Mass that needs to move.
2) The speed of the car - Using RPM, gear ratio and wheel diameter.
3) Add wind resistance (i.e. drag coefficient).
4) Derive the acceleration of the mass over the time.

You should be able to reverse calculate the output at the wheels to move it over time......... Thoughts ?
