Ferrari SF23

Yeah, seems like at most they'll use that tiny bit bigger, single pylon design. Brave

Brave indeed. Conventional wisdom would suggest that if they’re worried about tyre life and have a 10 kph advantage (vs last year), adding ‘dirty’ downforce might be a good idea.

So I hope brave doesn’t become foolish but I’m sure they know ten billion times more about it than I do!

I couldn't find the data from Pirelli about the working temperature ranges for 2023 tyres. It seems like the 2023 tyres are quite a bit faster, operates under lesser pressures (more grip) than last year and potentially have wider temperature ranges. If these things are indeed correct, then tyre life is not going to be such a big pain for Ferrari. So they don't need a whole lot of dirty downforce. If the car doesn't slide a lot, causing wear, then there shouldn't be a big concern. They can probably find a bit more from the floor as the development continues.

Agreed - seems to be the approach. Very brave, let's see if it pays off

If a DRS flap splits, can they repair that at the circuit within a week & put in preventative measures? You think they'll race with the single pylon despite the issues in testing?

They might just have gotten a new wing ? Anyways they only had 1 at testing, so were planning to get 1 new. Could have gotten 2 new.

Can see a bit of underfloor sculpting here I think.

Bigger beam wing upper flap than seen in testing. Not as big as last year, so this is something like medium-downforce beam wing The nuances will be crazy in 2025 the way things are going

Can see a bit of underfloor sculpting here I think.

I think that's still the chassis bottom...

I can see it already.. Bahrain 2025 we will be debating whether a beamwing is the monaco 2023 spec, the Suzuka 2024 spec..

That BW is certainly larger than the one they used in testing - yes. To me the spec looks like the one they started 2022 with:



F1-75 ^^^^^^

I'm not sure what to think to be honest. It looks close, but last year the flap trailing edge was clearly above the exhaust centre and now is right at the centre.

Maybe the exhaust is now 5-10mm higher...

They did change their exhaust this year with the removal of their funky wastegate so I like that idea

[Xyz22]

The rear wing is still the same used in testing, correct?

[Vanja #66]

Beam wings are definitely new (unless no one spotted them last year), exhaust is pretty much where it was.



Damn, I love my trained eyes, perfect geometry+CFD vision

The rear wing is still the same used in testing, correct?

They are registering them for this weekend, doesn't mean they will chose to run them, but they will test them.

Even if this is still testing data and we have arrived at the Race Weekend itself - some telemetry from Leclercs and Perez fastest laps and longruns :





It's noticeable that Leclerc only really uses 8th gear on his fast lap, while on longruns 8th gear was almost not used at all. There is no increase in engine revs when he was doing his fastest lap. In relation to the gears - RBR pretty much the same, but on their fastest lap engine revs were higher. I think you can conclude from this that Ferrari is definitely getting more from the PU side. While Red Bull released 500 rpm more on its fastest lap, Ferrari stayed at very low revs.

The central part of the diffuser has changed and is now more similar to the Red Bull, isn't it :

Testing Ferrari - Red Bull

That isn't Ferrari today I think that's from Baku '22 I believe

[Vanja #66]

That last one is F1-75, I posted it for beam wing comparison, sorry for confusion

Two very naive questions about that heavily downwashing driveshaft:

I was under the impression that suspension/driveshaft elements were mandated to have a neutral angle, is it not the case?

Is that bit considered far enough from the diffuser exit so that some downwash might actually help drive the rear corner winglets by increasing their AoA rather than inducing separation in the diffuser edge itself, which is most sensitive as it's where you also go for lateral expansion at aggressive radii, although far less than pre-'22. The fact that the trailing edge only dips down towards the outside would point to that. Would the downward transition combined with the relatively high camber of that wing body also help achieving that 45°-outwash effect that they're aiming for in the diffuser corner?
