Ferrari SF-24

Somethings that were noticed by myself and @organicmeasure

The deep recess underneath the floor stay, might have been discussed here not sure. It's purpose far outside of my technical know-how.

Second thing, the pink lines show the diffuser expansion, or so I think, which seems to start incredibly early, almost mid floor. Far earlier than other team I've compared to.





Here's AMR24 for comparison.

I don't think there is a deep recess under the floor stay, honestly looks more like a lighting thing making it look a bit weird, but yh I must say that kick looks like it starts pretty early.

Was this posted already? The waterslides didn't look this aggressive in the renders.

I think that's not a recess. It's a lighting playing tricks thing.

It's more clear here:

If this is a recess—being the roof of the underfloor—it would be protruding into the venturi/diffuser, so not sure what that would be for.

Also, this does not seem to be noticeable in the picture on the post just above.

^^ This shows pretty clearly that, contrary to Piola sketch on it.Motorsport (used as the reference here), not only has the upper wishbone forward pick-up been moved up (red dot) but the lower wishbone forward pick-up (lower red dot) has also been moved up, as I would have expected.

I say “would have expected” because as shown here it appears SF-24 maintains a similar level of anti-dive effect as last year’s car despite having the wishbone pivot axes inclined in RB fashion:

https://i.imgur.com/IGMSQPx.jpeg%5b

Also noticeable is how relatively low the Instant Center (IC) is and how small is the anti-dive effect—shown by de-composing the braking force into the force fed into the sprung mass and the force acting to lessen the compression load on the suspension (in the opposite direction of the tire contact patch trajectory).

All this assumes that the rear pickups have not been lowered, but if they have—for obvious aero reasons—then the anti-drive effect will be further lessened.

I never could understand why this trend of inclined wishbones became known as “anti-dive” because it’s just the opposite. As shown here, a horizontally pivoted upper wishbone with aft-inclined lower wishbone results in a much greater anti-dive effect:

https://i.imgur.com/BowZHzx.jpeg%5b

Angling the upper wishbone similarly would result in even more anti-drive effect. So what a lot of “tech writers” are calling ‘anti-dive’ on the current batch of F1’s should, in fact, be calling the design ‘anti-anti-dive’.

All this to say that the next time you read an article that mentions anti-dive to describe the inclined wishbones, know that the author doesn’t really know what he/she is talking about.

Thanks for this post which finally puts right the nonsense of so-called experts that the anti-dive value has nothing to do with how much the upper attachment points of the wishbones "drop off". I can't hear it anymore! Unfortunately, these so-called experts have already polluted 99% of people's brains. Unfortunately, this is also the case in other areas because people are constantly being preached a dangerous mixture of truths, half-truths and utter nonsense.

Interesting, thanks. I've no formal engineering knowledge, so... in simple terms this means that the changes in the arms positioning we've seen through 2022 and 2023 is purely driven by aerodynamics reasons?

Indeed, looks like a small indent on the top skin of the floor, it could have little to no influence on the bottom surface.

Was this posted already? The waterslides didn't look this aggressive in the renders.

Think that's just how sunlight hits that area, making it look deeper than usual.

Well said, thank you. My thoughts exactly.

Maybe this angle can convince you? The reflection seems way to odd to just be a flat surface

[KimiRai]

At first I thought that was a hole too but it might be the sun being casted on some piece higher up, not completely sure anyways

In recent years, the wishbones have always been used to influence the cars’ aero and this current trend of inclined wishbones started by Red Bull for the ‘ground effects’ era is just another example.

The inclined wishbones may also affect caster and camber changes in, for example, roll with steered wheel when cornering but with the the way this generation of cars are stiffly sprung this is probably not a consideration.

If in doubt, recall that no fully enclosed holes are allowed in the floor.

Anti-Dive Geometry: To prevent excessive front-end dive, teams like Red Bull use a clever suspension geometry. They set up the front suspension so that when you hit the brakes, the front of the car doesn’t drop too much.

A.I. much or article pasted from somewhere? Basically not saying much except, yeah, that’s what anti-dive does and, no, not why Red Bull incline their wishbones—cleverly or otherwise.

Why It Matters: Keeping the front of the car higher during braking helps maintain stability. If the front end dives too much, the driver might lose confidence because the car becomes unpredictable. Imagine turning the steering wheel while the car is bouncing around—it’s not ideal!

This is all wrong: not only does anti-dive not stop bouncing but a couple of drawbacks of anti-dive geometry is that it reduces compliance over bumps while braking (more harshness and bouncing) and it reduces steering feel… hence why too much anti-dive is not desirable.

It was clear from the previous pics that it's not a reflection.
But as Vanja#66 pointed out "it could have little to no influence on the bottom surface".
We do not know how little or it has no impact at all, maybe some of the drivers will make a presentation.
