I'm not sure if its just good downforce. It might be weight as well. Does anyone have an order of cars by wheel base length? I've been curious to learn where the cars are different in that aspect.
The Mercedes has lived up to its recent trend of concept: efficiency and low drag over downforce. The concept is extreme and the downforce performance hinges on that floor maybe even more than the other cars with the bulk-sidepods. So, the fact that their unresolved porpoising is in their way from really activating the peak potential of that car concept is not surprising. The more the raise the ride height, perhaps the greater the ratio of downforce loss there is on their car because its even more sensitive and dependent on this than the others?
If they sort out the porpoising (and I have no doubt they will) I won't be surprised if that car supersedes the rest with margin.
