Hopefully the car improves for tomorrow. The continued unpredictability of the car in terms of how it responds to the base setup implies to me they're still having significant correlation issues between the simulator and track. Maybe not something that bodes amazingly for 2025
Yep. Its a worrying sign for sure. Even Marko saying a few weeks ago about the need for a new wind tunnel to be bought online still a fair way off.
But to wonder if perhaps some of the issues are baked into the car design they now the issue but with budget cap and limited WT time etc they can't just spend their way out of the problem
The problem with the RB20 is quite clear imho. I watch every onboard from every session from Verstappen (yes I'm nuts). The core problem is a baked-in shift in aero balance. So the center of aero balance shifts in such a way that the car is never good in a variety of corners. It is normal for this balance to be more on the nose in slow speed and more on the rear in high speed. With the RB20 this doesn't happen in a correct way, which results in a car that either is very understeered in low to medium speed OR oversteered in the high speed, which is what you really don't want. The car is also very unpredictable like this. Then the second problem, which Verstappen often refers to as design limits on the car, is that the mechanical part of the car doesn't give the freedom to compensate for this behaviour. Which basically means things like suspension geometry or differental options/limitations.
The first problem can't be fix in an instance because of limited wind tunnel time, but also because I assume they have or had correlation issues, which need(ed) to be solved first. It seems they now have an understanding what to do, but it is/won't be fixed on RB20. The mechanical problem probably (front suspension) requires a new chassis design.
BTW, it you watch the onboard of Verstappen, it is not uncommen to change his diff setting multiple times a lap (he used push and pull toggles for this) to compensate for this car behaviour.
