Ferrari SF23

[FDD]

I can see that the lower outwash portion of the sidepod is pretty longer than on F1-75, also with bigger undercut.
This part was extensively discussed here by Vanja#66 and Andy76 and and Alberto Aimar on youtube channel, regarding the drag generated by the sidepod in this area. If I remember Vanja#66 find some stagnation in air flow in the very beginning of the vertical part of the sidepod on his CFD analyses.
Also I think that rear rod on upper triangle of front suspension is linked on the nose lower than earlier, similar to RB and Alfa.

Ferrari started using internal ducting behind radiators almost 10 years ago. With these louvers, no need for internal ducting, just slam the bodywork right over the radiator.

I bet they work like MP4-29 chimneys or A522 letterbox slot, like a pressure relief valve to help the cooling system, thanks to their placement in a particularly low pressure area. A cooling exit on steroids that will stay on the car, unlike some of the shark fins.

Also it looks to be two slotted outlet.

That's one hella ugly looking SIS

Enrico Cardile, head of chassis:
"Our 2023 car is an evolution of the one we raced last year, but in reality, it has been completely redesigned."
"In aero, we increased vertical downforce, to adapt to the new aero regulations and achieve the desired balance."
"The suspension has also been redesigned, to support aerodynamics and increase the range of adjustments that can be made to the car."
"In the front suspension, we have moved to a low track rod. The front wing and construction of the nose is also different."

The bathtubs themselves are barely bathtubs now to be honest. They are far less scalloped than last year

Vasseur: "In the past we may have had to underpower the engine, while now we are back to normal"

I'm glad they didn't work on their horizontal downforce.

I think this is the first statement on downforce improvement in spite of regulation change from any team member, of any team. Some theorized this is possible, but is now confirmed. I expect other teams achieved this as well.

It was to be expected in second year of major rule overhaul, I predict all cars to be faster than last year. 2018 cars were vastly faster than 2017 ones despite some rather major adjustments to rules that had detrimental effect of performance, not least adding an anchor like entity right on top of f1 cars (halo ).

Maybe development scope is narrower nowadays, but it's still not gonna stop engineers to claw back lost performance and some more.
