How does the mass of a co2 car affect the performance?
A larger vehicle has a tendency to be slower to accelerate, have a lower top speed and not be as nimble around turns at higher speeds than a lighter car. On the other hand, with a good set of tires, a heavier car has a tendency to have more traction than a lighter car. It all depends on how the chassis is set up and what kind of engine and transmission are actually on the vehicle.
