Top speed and the 240kph+ curve looks the same to me between the RBR and FER cars. At least on a single lap I don't think they have anything to do to catch up there with the current wing setup.
race sim picture above here.
* NOR on Hards, LEC on Softs, everyone else on Mediums.
* PIA kind of all over the place, maybe traffic, but did have a bit of degradation on mediums, still would be low 1.35s without the outliers.
* NOR on Hards could keep the pace of the rest.
* ALO had the 2nd longest sim with 11 laps, and showed some degradation
* PER all over the place with the longest race sim, not a lot of deg, but the lack of lap consistency in the middle helps degradation. good pace
* RUS/HAM basically ran the same thing for a very short number of laps, seemed pretty equivalent to me around 1.34.4/5
* SAI deg looks quite good and wasn't excessively short, compared to others, so there could be a lot of room for time improvement there.
* LEC on softs was starting to show some deg towards the end, but then placed that 1.33.8, could probably have gone faster earlier on.
* VER pace is 0.5s ahead of everyone else, but it's not that much ahead of PER if you take out PER outliers. Very good deg of course, but times were slowly converging to his time from at least PER/SAI/LEC and maybe the Mercs.
Could be Max doesn't need to worry about early stints too much and he builds the gap, but then pace differences come a bit closer as the stint goes.
RBR > FER - MER > AMR > MCL
is my pecking order based on this. Up to MER to demonstrate they can keep the pace on full fuel when they have less fuel on (unlike in Bahrain).
