does the nose have to go out beyond the wing like that?
Yes and no. It is compelled to go beyond 1150mm ahead of the front axle line (the picture is ~1350mm which is to the maximum overhang). The front wings apex has to be between 1320mm and 1350mm. If you move the nose tip back it would expose the mainplane which is only really an advantage of you keep the whole of the bottom surface free.

When viewed like that it makes me wonder why they do not put a limit on front overhang, it would naturally limit the front wing aero & the front floor aero as the nose structure (and therefore the forward chassis structure would need to be lower - particularly as the nose height is mandated).
The increase in height of the tyres is ridiculous!!
There are limits on the overhang (as above) they're just longer than 2021. The nose in 2021 has to be at least 1075mm long up to 1200mm long, everyone just runs the shortest they can, while 2022 is 1150-1359mm. So I admit it is shortest possible 2021 nose vs longest possible 2022, but I think these are probably about as long as they will be (give or take 20-25mm).

The tyres are ridiculous. Bigger even than Le Mans. The teams didn't want really low profile so they bulked up the sidewall, typical F1 "compromise".

Hi IJN,
In tech regulation doc, front wing profile is no more than 4 parts, why in your picure FW is just 3 parts?

And also, in regulation doc I cannot find the plate above front wheel, do I miss something?

The front wing has to be 3 or 4 element. We chose 3 because it's fewer elements to tweak/optimise. Each wing has 3-5 planes across the span where chord, leading edge thickness, camber (set by leading and trailing edge angles), trailing edge fishtail, trailing edge thickness, slot gap, slot overlap, element incidence, among other parameters are set for each element. Another element is all of those parameters 3-5 times across the wing.

Nope that part is not freely available. We had to make it from the pictures released of the wind tunnel model and a bit of experience. The regs document is also missing, the actual cockpit entry template, the wheel covers, the rear wheel winglets and vane, the halo, side impact structures, and the plank. Among other things.

Working on some CAD (as ever) for CFD which may never see the light of day. Thought I'd share a visual representation of how much longer the noses on the 2022 cars are than 2019-21, and how much bigger the 2022 tyres are. It's rather shocking when seen side-by-side.

That new front wing is begging for a 150mm wide Catfish bridge from nose to endplate... 🥲🥲
