Most interesting image of the lot IMO

Some images taken by the Sky Italy documentary about the Scuderia.
I fount interesting the CFD of the F1-75 (not properly the F1-75, maybe an evaluation of possible improvements, it's an hybrid between SF23 and F1-75)

Can't help but notice that ambient pressure zone (gray) just casually corresponding to my eyeball-cfd expectations a year ago No wonder they cut so much drag year-on-year, excellent pressure recovery on the whole rear end of the cover

I guess the overall tighter bodywork explains why the tubs are now shallower, they had to add a bit of volume somewhere. I don't think tubs' excessive depth can add more downforce and, in Ferrari/Haas execution, this downward slope also has a limited effect on reducing drag. So it would make sense the team chose to tighten the engine cover to "expand" the ambient pressure zone in the tubs.



Something like this, SF-23 is at a different angle so the length of ambient pressure zone is the same but shown according to the photo available. Regarding the width, I think this is why the team narrowed the engine cover further - to expand the ambient pressure zone laterally and further reduce the drag over the engine cover. The exact pressure distribution is not like this, this is just my rough estimate.

Existence of the "s-duct" has been confirmed in a recent documentary from Sky Sport Italy, featured on a late-2023 car:
