Ferrari SF23

[Xyz22]

New front wing tested in Filming Day in Fiorano today. A new floor was also mentioned a lot in the last few days, but so far nothing was confirmed.

The endplate and all 4 flaps connecting to it have changed. The endplate is a lot smaller now, rear edge is cut away from the tyres completely. On the front the top corner is curved and the deflector has a different shape. The flaps are fairly different now, with linear slope towards the endplate. The main plane is also changed, mainly the leading edge profile it seems. There is no overhead photo, so there is no comment on the overall planform surface change. I think we will need to wait for Thursday/Friday photos for that - if the new wing will be used in Austria.

I hope these changes will go in the right direction, which is a stronger front end.

According to Motorsport.it, Sainz ran only 50 of the 100 km allowed for the filming day.
The remaining 50 km will be run by Leclerc in the afternoon, when other new parts will be tested.

In the photo below there also appears to be a change in the lower part of the wheel hub internal cover (see front right wheel):

New floor features another change at the leading edge, this time much more significant than Miami. Venturi channel shape does not seem to be changed, so they still want to make that approach work.

The leading edge in the outboard section has been raised further, while strakes now protrude outside the floor planform. There also seems to be slight re-profiling of the cross-section, arguably the most important parameter. Together with sidepod and floor edge changes from Barcelona, this is now a completely different car from Monaco and previous races.

I wonder if they made significant changes to the underbody as well.

They also seem to have ditched the slot infront of the rear tire from Barcelona.


Now the edge wing connects flush with that rear portion.



Additional photo.

Not remarkably hi-res but some more angles of the filming day.

Interesting to see they have adopted the rounded floor strakes that poke out from the leading edge of the inlet. The other cars that do this IIRC are the Williams and AlphaTauri.

[dialtone]

Are the stakes in the venturi's mouth reaching further out or is that just the picture?

Edit: didn't read what continuum wrote but sounds like yes.

Indeed, goodspot, this wasn't clear from the formu1a.uno photo I posted. Looks like there's only a legality slit now.

It looks to me that front higher wishbone (front axle) is connected a bit higher.
Edit: Undercut looks deeper also to me.

[Sevach]

More frontal area in the FW i think.
Also a big gurney in the area that slopes down, previously Ferrari used a gurney in the middle when they needed extra downforce.

[organic]

Excellent analysis here, thank you Vanja, Sevach and co!

[gordonthegun]

There is also a small horizontal blade on the inside of the endplate just above the attachment of the last flap.
Haas has a similar one since the beginning of the season:

[vorticism]

The new down sloping engine cover panels permit those new convex large tall deep louvres (haven't seen those yet on any Ferrari '22-'23; usually much SMALLER and more numerous).

Neu:

source: motorsport network italia

Same panel with smaller louvers (prev race):

source: unknown

The previous panel in that area (previous sidepod shape) could not accommodate convex louvers on the cockpit shoulders:


source: unknown

Worth noting the new sidepod concept seems to eliminate forward louvers f.e. there is no longer any room for the prev black louver panel.

Think Red Bull and Mercedes make use of this too.
