Alpine A522

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

I wonder if it's legal to widen that 'tunnel' (purple) and shape it like a wing (like March 701 sidepods).
So if you cut the car along the green line, you get that shape (black)
This solution would guarantee you the titles for 10 seasons at least, obviously, but is it legal?

Don’t see anything in the regulations preventing that. Not so sure it would work well in cornering though.

I haven't read the regulations in detail, but my broad knowledge says no, it would not be legal. My basis for this comes from something mentioned in Kyle's video on the Mercedes W13 upgrade with the slim sidepods and the mirror mount wings.

I'm recalling this from memory, so the terms I use may not directly correlate to the wording in the regulations.
In the video, he explains that along a longitudinal vertical plane there can be a maximum of two distinct intersections. On typical sidepods with a standard undercut, you would get two intersections; one from the top surface, and one from the undercut (screenshot I quickly took of the video):
Image

Whereas on the Merc, you get one intersection from the mirror mount wing cross-section, and another from the sidepods:
Image

This is why the Mercedes sidepods have no undercut, because (to my understanding) if you had the mirror mount wings and an undercut sidepod (like previous years) there would be three intersections.

If you had the "wing" shaped tunnel like the shape in black, then you would have three intersections at the overhang; one at the top of the "wing", one at the bottom of the "wing", and one at the top of the "normal" sidepod shape, not including any undercut. The only thing that may allow it is how high that reference plane goes (which I don't know). Obviously it's these kind of weird, fine margins that can win you championships, and it takes someone more patient than I to read the technical regs to their fullest extent.

I initially was thinking along the same lines but then I struggled to understand RB's latest engine cover which seems to violate this.

Doesn't the trench already break that rule? Is the rule only applicable at the start of the sidepods and that is why the trench starts further back ?

As far as Red Bull goes, I also wondered this. Perhaps the reference plane starts at the Halo (or some offset from the centerline?) The "undercut" region is both fairly mild and is also quite narrow. Like I said, I haven't read the regs in detail; I'm trusting that as someone with F1 experience Kyle would interpret it better than me, but maybe we're both wrong.

As far as the trench goes, I drew a quick section view of a "generic" sidepod, with the plane in question indicated by the vertical lines. It should be OK (see left) as long as it doesn't cut back on itself (see right). (Hopefully I understood your question)

Different legality boxes for the engine cover and for the sidepods, I guess different “section” limitations too:

So Alpine would just have to copy the Mercedes sidepod shape : P (and find out how to prevent the extrados air from spilling over to the intrados low pressure* - that's one of th reasons the March 701 wing failed AFIAK, it needed a skirt to seal the low pressure side... like the later Wing cars)

Based on that rules link there is definitely different rules for the sidepod inlet and what they call Coke bottle section of the sidepod right behind it. Explains why the trench starts where it does. I think the wing would be possible, from a rules perspective, if it would start where the trench starts. If they could build something useful with an edge radii greater than 75mm and a added minimum permitted concave radius of 50mm.
