In addition, the reason to push forward some of the new bits was because they had to implement them and homologate them before the cutoff dates.Chicane wrote:Seidl has been categorical that this short term pain will be worthwhile for a better 2021. Remember, 2022 car development is banned till the end of the current season so Mclaren want to focus on the 2021 car with side by side learning from MCL35 till the end of the year.
I think once the 2022 car development ban is lifted the focus will shift to 2022. I don't think there are going to be many upgrades on thr 2021 car through the season. McLaren are front loading all the 2021 car developments now.
Seidl has talked about two really important reasons as to why they are bringing aero upgrades even if it means disturbing the situation, one being on track understanding of aero parts, two, confirmation of wind tunnel/CFD correlation.
McLaren has been in constant exchange with Mercedes about PU Integration ever since the deal was announced. This lead time will help McLaren. The air flow characteristics on an f1 car can be extremely tricky to optimize especially around the bargeboard area as the margin for error is basically zero. I wouldn't be surprised if there is further tweaking of bargeboard bits in the next race based on the data from the last race.
There are also parts that aren’t that visible (like the new nose) that may also need to be understood (suspension, mechanical) that may have been rushed in due to the freezes.
