Very decent analysisbananapeel23 wrote: ↑10 May 2024, 17:56Firstly, This is nothing compared to the hilarious mockery of the regulations that was the wing with a pseudo-endplate that Aston Martin designed and ran at Hungary and Singapore 2022.
Secondly, That thing is going to whip up a big ol' vortex, right? Wouldn't that be unnecessarily draggy as opposed to a smoother transition and produce a whole lot of dirty air? What purpose could an almost entirely detached upper element serve if it's draggy? I mean flat wing edges worked pre-2022 due to endplates, but surely they are way too draggy now?
Are they just trading aerodynamic efficiency for pure downforce by running the longest upper element possible? Does this huge upper element mean they can run a more conservative lower element/beam wing? I guess focusing as much of their overbody downforce as possible into the wing element that opens with DRS makes sense from that perspective.
Does the rear wing directly interact with the diffuser expansion in a way that could explain why you would want such a massive vortex?
I don't understand aero and I'm totally just guessing because I want someone smarter to explain or at least speculate. Does anyone smarter than me have a clue?
A bulge around the NGK logo has appeared and a small rear corner slot gap. The VG's for the edge wing are a little bigger and more pronounced, previously they didn't have a sharp corner.Vanja #66 wrote: ↑11 May 2024, 09:10The floor used yesterday was, in fact, new floor. You'd only notice it if you look for smallest of details while knowing there is a change somewhere. The rear area near the edge has a different curvature and was flat before, a very small change but the only one I saw. Once you finally spot it, you can see it really is a bit different from every angle
From the rear side angle it looks like the undercut might be a bit deeper on the inside, but it's impossible to judge for sure. The top front part of the floor looks virtually the same, not even a slight change. This does not mean it's a bad thing, it simply means Ferrari are making targeted, cost-efficient changes and clearly the underside has changed and this is the part that matters.

That’s a rear wing design that is taking advantage of reduced drag in the rest of the car to increase wing size while overall drag stays the same. I wouldn’t be surprised if next race Ferrari has closed the top speed gap and DRS gain as well.Vanja #66 wrote:A few more details worth mentioning. Well, more like defining the scope of the changes visually and comparatively.
New sidepod shape has been noted as slightly tighter and evolved. What I didn't notice so far is that the inlet undercut is definitely higher now, I would say around 20mm. What's more, the entire silhouette is very similar but clearly tighter and evolved. Might be slightly lower drag overall. The shape of the rear waterslide wall looks flatter (Ray Ban area) and Formu1a Uno guys point out at this with top green arrow, so most likely there is a change here as well.
The SIS tube cover is also slightly smaller longitudinally, but still similar in shape.
As for the rear wing, the change is bigger than just the flap tip. Endplate joint is completely different and features shorter local chord, while the twist of the flap towards the tip is significant. This section is now less cambered than before, so I believe the aero efficiency of the wing is most likely improved with this redesign.
With all these details popping up today, the changes of the bodywork and rear wing look a bit more substantial than what it appeared initially. And again, the most important changes will be the ones we don't see under the floor.
Norris was 3-4 kmh quicker than Piastri in SQ in Miami with new bodywork. However they were equal in Q session, with Norris now being slower, so I think he decided to add a bit on both wings, typically he was 1-2kmh slower than Piastri in Q sessions before Miami. I wouldn't be surprised if Ferrari gain 2kmh with these changes, but it will be difficult to quantify this if Red Bull make a similar gain. We'll see what the situation is in Q3 in Imola
It's more like theyre obsessed with flow to the rear wing. Thw triangular roll hoop is another thing they tend to do to reduce drag going to the rear wing. So yes a lot focus for them is that flow path above the engine cover leading to the wing. Maybe the cobra winglet enhances the flow at the new sharp rear wing tips to give better top speed. We shall see.bananapeel23 wrote: ↑10 May 2024, 15:10Man, Ferrari really loves spending time on weird halo decorations.KimiRai wrote: ↑10 May 2024, 10:43https://pbs.twimg.com/media/GNNFa-3WEAA ... =4096x4096

First the halo mirrors in 2018 with a winglet hanging off. Then the SF23 with the weird little wings sticking out on top of the halo. Then the first iteration of the SF24 winglets that created a tunnel between the sidepods and the halo. Now these weird S-shaped "cobra" winglets on the SF24 v2. Nto to mention all the small halo covers and the tiny winglets that barely stick out that were used on the SF21 and F1-75.
Why does Ferrari spend so much time and money on halo ornamentation while no one else does? Are the performance benefits thought to be significant at all or are we talking thousandths of a second per lap?
What purpose do they even serve? Is it akin to something like winglets on aircraft that aim to break up vortex formation and reduce drag downstram? Is it more of a flow conditioning thing meant to keep the airflow flowing off the halo nice and predictable when it hits the rear wing?
The sis cover being smaller could mean more floor volume underneath. Ferrari could be going more aggresive with the floor having understood how close they can go up against the porpoising limit without the car bouncing too much. I would expect more highspeed grip if the floor is new as well.Vanja #66 wrote: ↑11 May 2024, 20:41A few more details worth mentioning.

This outlet reminds me of the F2004. Bigger, but already on a Ferrari 20 years ago.Vanja #66 wrote: ↑10 May 2024, 14:06It's obvious what the new engine cover outlet looks like, but visuals are always better. The top outlet might be blow-through-flow from S-duct basically

As ringo has rightly said - this is all to do with Ferrari being unique in terms of a different philosophy - narrow airbox and engine cover, which aims to bring benefits to the airflow to the rear wing (next to a lower CoG due to the low positioning of radiators etc). The work in this area is aimed at further optimizing this airflow and the slight advantage you have here thanks to this philosophy by reducing losses. These are advantages that are actually in the range of thousandths of a second.ing. wrote: ↑10 May 2024, 20:40The ‘cobra’ looks do be doing the exact opposite of aircraft winglets—it looks designed to be a VG, shedding a vortex off the outboard tip of the top horizontal plane, which also looks to be cambered and generating some small amount of DF.bananapeel23 wrote: ↑10 May 2024, 15:10Man, Ferrari really loves spending time on weird halo decorations.KimiRai wrote: ↑10 May 2024, 10:43https://pbs.twimg.com/media/GNNFa-3WEAA ... =4096x4096

The vortex is likely used to strengthen and direct flow over the engine cover.
The twisted support below is either aligned with the flow or is being used to clean up or condition the air coming off the cockpit opening/halo anchoring area.
Good observation, I have already thought the same thing, although the angle can be deceptive here. However, I have also heard that there have actually been slight, barely visible changes in the suspension area.miguelalvesreis wrote: ↑11 May 2024, 02:07Isn't the front suspension geometry also different??

To be honest, I don't think there's any cause-effect relation in this case. Ferrari didn't make any changes to the top side of the floor in frontal area and they could have both decreased and increased floor volume underneath, the chassis and SIS tube weren't changed. That said, their underfloor is quite different from any other, with a sharp leading edge and a very high tunnel roof at the front, with a big sudden drop to under the SIS tuberingo wrote: ↑12 May 2024, 02:15The sis cover being smaller could mean more floor volume underneath.

Very nice catch Andi, thanks for sharing!
Those diffuser strakes are very reminiscent of the floor inlet strakes we have now!Vanja #66 wrote: ↑12 May 2024, 10:13
