Sorry for not having time to read all the pages but I would like to ask you guys, here that have better knowledge about aerodynamics, if the RB18 car has more downforce than other cars on the grid due to the bigger amount coming from the diffuser rather than Venturi tunnels. My theory is based on the fact that HAM said prior to Canada race that they raised the car`s ride height and maybe that's the obvious reason after seeing in the race almost no porpoising, less bouncing, better kerb ride and higher top speed.
Let me explain ...
From the Baku pictures, we could see on Sky that RB18 is running with some rake so could it be that the floor is designed to have a linear shape, in order to withstand a speed until porpoising is occurring, then at the back have an upward slope? This could give them in the end the most overall downforce coming out from the diffuser rather than Venturi tunnels. In other words, they choose to sacrifice the maximum downforce that is coming from Venturi`s which is inconsistent and lends to porpoising (best proof is W13) and rather they were choosing a floor with a lower and useful/consistent level of downforce with no porpoising at which they add a higher amount of downforce produced via the old fashion way, through the diffuser. Thus way RB18`s overall downforce is bigger than theoretical W13`s simulator downforce levels ...
And this car design philosophy could also have other benefits coz when you rise the car`s ride height you could have more suspension travel and ride better over the bumps but most of all the kerbs (where you could gain/find more time with these 2022 cars, just see Canada race). And last but not least, having more downforce you could trim the rear wing for more top speed, something that RB18 did successfully this year ...
On another note, how about a damper driver seat system just to cope with the porpoising/bouncing/bottoming issues? I think that if W13 were faster than RB18 they would not be moaning so much about it, isn`t it?
