Looking forward to Qualy
6 tenths from 3rd to 17th in practice 3 - could be great fun 🙂

Must have been a very nice feeling passing two Mercs & a prancing Horse to pick up a podium😁

it looks like Mercedes have finally decided to ditch the no sidepods design from last year and get back to what everyone did last season. Something they should have done last year and been more competitive leading to a much better start to this season🙄
I fear it may not be as simple as that. It appears the side pod is not the main differentiator but the
underbody aero is . I also think two things happened which didnt help. First they won a race in Brazil which made them thing maybe there was something in their design after all and second by their own admission they compromised the underbody design anyway to be absolutely sure that there would be no porpoising.

I saw an interesting video on youtube " A masterclass on underbody aero by Wilhelm Tott" a well know ex F1 aerodynamicist who I think is known by someone on here. He showed the causes of porpoising ( underbody stall with delayed downforce recovery ) and hinted at means to achieve high downforce without getting near to this condition. This I think is the Red Bull secret sauce and something Dan Fallows of Aston Martin knows well being ex chief aerodynamicist at Red Bull.
I understand that the downwash side pod design is but one of these means

I think Mercedes now have to go on a steep learning path to discover what works and why but with
windtunnel design time restrictions. I think they've got an uphill task unless they can hire someone
with the knowledge as Aston Martin cleverly did.

However I do hope they get somewhere fast and other teams as well as a Red Bull 1-2 whitewash
will be as bad if not worse that previous team dominations in the past.

Willem Toet was head of Aero at Benetton, Ferrari, Sauber and joint head of Aero at British American Racing. And yes, I have known Willem for 25 years now (I met him at BAR).

Avoiding porpoising is one thing that the teams need to do, but it is not the RBR secret sauce, they have done far more than that.

Fundamentally F1 was stuck in an aero groove where micro optimisation of the aero configuration was required. The 2022 aero regs changed all that and a very different flow field has to be understood and then optimised somewhat. All of these cars need an aero solution that is developed across the whole car and taking, for example, the RBR sidepods and putting them on the Merc is very likely to make it slower.

And yes, the budget cap, which was designed to being the grid closer together (which it has other than RBR) will mean that it will take longer for teams to catch up with RBR, but they will at some point unless the rule makers mess with the rules again, which would spread the grid out again.
