OT, but I wonder which team sought clarification?

Back on topic…
Kyle seemed to think that the duct entrance, exit (and probably whole duct) are in the “mid-chassis legality box” in his assessment of the car, thus avoiding minimum radius rules that apply to “bodywork”.
If it is ‘just’ an s-duct variation, the entrance is much larger than the outlet; would this re-energise any turbulent flow ingested?

According to media reports there were "several teams" who sought clarification.

It’s tough to tell since the angle of these pictures isn’t the same. I do think the angle of the pushrod is slightly sharper (ie a smaller angle) though and the lower suspension arms are lower than last year (presumably to give them more setup flexibility?).

The fact that "the lower suspension arms are lower" implies a thicker chassis in that area but it seems to continue to be thicker going to the nose as well.

"Enrico Cardile, the technical manager of the project, explained that “… the most evident changes of the new suspension are certainly in the front area, where we have gone from a configuration with a high track road to a low track road, guided by the needs of aerodynamics”. The Italian engineer also underlined that “the front wing is different as well as the structure of the nose”.

The approach of the front has been changed more than it seems: the two triangles with carbon covers that have been specially designed to laminate the flows according to the wishes of Diego Tondi’s staff, the Ferrari aerodynamics chief. Not only that, but the suspension arms have been lowered so that the chassis is also in line with the nose which is more hollowed out on the sides in the lower part.

Even in the yellow dotted line, the chassis rises towards the Venturi channel and the vertical intake of the bypass duct is not overlooked, a sign that the introduction of this concept has been evaluated with great attention in the definition of the entire front part of the SF-23.

The photo from Motorsport Italy allows us to see that the keel of the SF-23 reaches the leading edge of the tea-tray, and there is no longer the double splitter that Ferrari had immediately copied to the Aston Martin AMR22 already for the presentation of the F1-75." - quote from Scuderiafans

Do You think that kneel now generate the vortex instead of the splitter before?

Hard to say because this area has not really been seen properly. But I think rather that here the mentioned major changes of the strakes will be decisive and they are also the reason for the changes to the splitter. Just like the underbody itself of course.

Here the differences of the geometry of the front suspension and of the engine cover.
The front of the chassis, starting from front suspension area, appears to be taller than last year.

In this picture, it looks like the inlet for the venturi ducts has changed quite a bit. It looks wider.

Look at left rear tyre. The angle is significantly different. As is the undercut much larger, distorting things further. Every team was at the maximum legality for the tunnel entrances last year already as far as we could tell

How can Scarbs know this?

The way that s-duct has been drawn looks very angular. It almost seems like it would cause some additional drag with air beging forced into it, hitting angular walls and then proceeding outward?

That was very quick. I was expecting at least a couple of races before any other team adopts it.

Merc looked like they already had one last year for a start just much smaller and in the sidepod entrance itself. Wouldn't be hard for them to take it as far as the Ferrari solution

He said they didn't copy it but rather multiple teams had thought about trying it in 2022. I imagine they didn't because it would add weight that in '22 nobody could afford

This is a subtle point, but if you just look at the Mercedes radiator inlet, you can see why an "s-duct" is redundant for their car. The low radiator inlet (as opposed to the high inlets on everyone else) already ingest the turbulent boundary layer before the air travels around the sidepod. Less obvious on the W13, but blatantly obvious on the W14. The W14 rad inlet just looks like a much wider and taller Ferrari s-duct, if that makes sense.

Maybe it doesn't appear at first glance, but the SF23 seems to be quite slimmed down and cramped in many of its aspects.
