What's the top speed on your car?

Gotta agree with Unit. What determines your top speed is drag, which is a combination of aerodynamics and friction. Aero drag increases exponentially with speed, so aero drag is the biggest factor that determines how fast you can go.

More weight might may mean more rolling friction, but it has minimal effect on top speed. It just takes longer for the heavier vehicle to get to terminal velocity.
