Ferrari SF-24 speculation

[FDD]

Talking about the flow management around and inside, I can agree that certain kind of revolution is posible in the way how the rules are interpreted.
Do they make this revolution I do not know cause I am not an aero guy and I am relaying on your expertise.
Also if you have time and will would be good to make some analysis/explanations on that subject to present here cause it is important for the 2024 car.
I would be very grateful and would be happy to read it.
Thank You.

Unfortunately, there is not a lot that we know for certain, neither about sidepod-diffuser rear corner interference nor the floor flow structures in these complex RB-like floors. As for rear corner and diffuser flow management, what Ferrari had in 2022 was working very well obviously, but in 23 the floor edge got higher and they made their launch sidepods without a big side wall surface and much more tapered, which left a lot more of the floor exposed. In my view, downwash sidepods are working better with 23 rules because they somehow prevent the dirty air (and crosswinds) from entering diffuser better than 23 launch inwash design from Ferrari. The area in question is circled in green here

I believe the mechanism at play there is literally having a wall that generates slight pressurisation in yaw in that area which is forcing the dirty air probably up and towards rear tyre. The thing about this is that very small changes in pressure in this area can have big consequences for the path the low-energy dirty air will take. If you only look at flow-vis, you might get a wrong impression that all the air in this space is always going towards diffuser mouse hole, but in reality we don't know what is happening 20mm from the bodywork surface, much less 50 or 100mm which is very important for understanding what is really going on.

So how all this will translate to Ferrari 24 car, I have no clue I really wouldn't be surprised if they go full-width downwash ramp. Nor if they keep their hybrid solution slightly changed... The front will be very RB-like for sure, that much is certain, I think they should skip right to the final RB19 inlet and undercut design, no need to go step-by-step with the new car.

A car 2 years advanced in design (2024 car) should be faster than a 2022 spec car in every kind of corner no matter the circuit, especially an early 2022 spec car. It's a strange comment.

Considering how bad SF-23 was in some corners compared to F1-75 even in the final spec and especially early in the season, it's valid for Ferrari staff to point this out. It's not a big statement, I think they just pointed it out to quantify they see a definitive progress with the new car in an area that was a weak point.

Thank you very much, very informative and educational.
I want to mention about the AR car when I saw for the first time that pic with flow-wiz of the car I was amazed how huge inwash the car have, which was completely unpredictable from visual inspection of the body work, at least to me as F1 fan.

The stability of the regulation, the experiences of the other teams added to some indiscretions do not leave much to imagine.
So, is this, more or less, what the 676 will look like?

Aero is not the problem, chassis, suspensions and the floor is where all the magic is done

Aero is the problem. In fact, all the changes being made are in the name of aerodynamics.

Suspension works in harmony with aero devices. Chassis changes are to allow more freedom to develop, in season developments are majority if not all aero chances. You've mentioned floor which is an aerodynamic device. Aero is king and will always be.

The biggest visual changes that’ll be seen most likely will be the side-pod area and the front/rear suspension… doubt anything drastic will change around the front/rear wings or indeed the airbox area. Only thing that might be slightly different will be the rear diffuser, but even the all the major work you’d expect to be underneath so not exactly visible.

If they’re still concerned with weight, they’ll probably stay with this type of livery with parts of exposed carbon to minimise the weight… though I hope they change it; F1-75’s livery was much nicer/cleaner to me compared to SF23. Would kill to have some nice design on the rim covers (weight issue obviously)… something like the good that Alfa Romeo ran at Monza this year… a call back to their retro liveries.

I disagree wrt the front wing. Feel it'll change a lot.

Yeah, both cars will have the same 4 wheels, roughly the same airbox and the same rear wing. Other parts will change, but those are less important

Joking aside, that's a nice looking illustration, but the fact is the front will change, the sidepods will certainly not look like that (will be bigger and have more details) and I think they will have their own rear end of the engine cover design. The floor will be completely different too, of course.

This is quite evident by reading Newey book. Every change to the chassis, gearbox and suspensions was mainly to achieve specific aero targets.

As I know is the side impact structure. Mercedes with zero sidepods used it as a mirror holder. In 2023 Redbull the lower structure builded in the floor. In this photo probably want to illustration ,that Ferrari do the same.

This is suggesting the very likely scenario that the lower SIS cone will be moved down to the roof of the floor instead of where it’s been the last two years and where last year it poked out of the undercut and so likely compromising the flow there and limiting development.

This is basically just rehashing what has been speculated elsewhere, but with graphics for non-Italian (or French) speakers.

Interesting that the new buzzword among the “pundits” is anti-dive, thinking that RB have a high anti-dive coefficient because of their aero-driven inclined front upper and (significantly) lower wishbones, which is not the case.

Further stating that the anti-dive geometry reduces porpoising—which is most evident at speed on the straight when no braking is involved—reduces the credibility of this prediction.

Also, it would be disappointing if details of the car are really being leaked by Ferrari insiders.
