Help calculating max speed of my electric car

What would be the max speed of my electric vehicle? I need a systemic way to calculate this given BLDC ratings: Voltage, Rated Power, Rated Speed, Rated Torque, Rated Current, No load Current, No Load Speed. Also using these constants: Weight and coefficient of friction. There are two motors. We are ignoring any resistance from the shape of the vehicle. The car is in a vacuum.

This is what happens when you don't do it systematically and by failing to recognize your constraints and degrees of freedom.

Matt gets an F
Nope Matt gets an A - the problem was a car in a vacuum - no wind resistance - and the only place with lots of vacuum is space so no rolling resistance either
