What's the top speed on your car?

[MiracleMax]

Well I gave the mass/velocity statement a thought, If say for instance your car was able to operate in a vaccum, and had unlimited gearing so that engine speed nor drag was an issue, then eventually the relativisitc mass of the vehicle would become so high, the power produced by the engine would be unable to accelerate the vehicle from one velocity to another. Making the statement true in the that mass does have an effect on terminal velocity, but only in the relativisitic sense.

On a more practical level a car or any car is unable to generate suffcient velocity through gearing or power, for mass to have a substantial effect on terminal velocity. Hence aerodynamic forces (drag/friction) are the limiting factor here on terra firma.

I never dabled with physics in school, so I can't say if newtonian physics indicated an increase in mass as speed increased, but instead held mass as a constant depite the velocity of the vehicle.
