Yes, but to a certain degree we have aero to help us with that on the high speed sections of the track. On the low speed sections, less mass is easier to turn, brake, and accelerate so you can go with less grip and overall less energy expended which can turn into longer runs and less heat generated as waste. Which leads us back to the original point of this post; you can use less battery and less motor to save on weight and mass in motion to get the same result.
