The more I look to these tunnels, the more I find them complex and very different from the wing cars and the champ and Indy car tunnels.
The tunnel shape seems quite conventional and almost identical to the Swift Formula Nippon car to me, albeit with the "second kick" (extra reflex section) that is popular in modern day time attack cars and also seen on Newey's Aston Martin Valkyrie.

The tunnel inlet seems almost identical to the conventional Champcar style with vortex generators.

The F1 car seems entirely
consistent with conventions to me -- the inlet with vortex generators, and the "second kick" in the diffuser profile that is popular in modern time attack / hypercar design.
IMO it is exactly the design you would expect for an open-wheel venturi tunnel car targeting F1 downforce levels, with the only unexpected touches being the wheel covers and front wheel air guide (which are of course beneficial to tyre wake management, but sadly not for the aesthetics of the vehicle).
Well: at least it is exactly in line with the design I had imagined in my head for a hypothetical F1 rival series, using AER twin-turbo V8 engine with 1000hp (except I would use the classic Grand Prix 2.15m car width)!!! It would race at classic tracks like Sepang and other dropped F1 tracks, being primarily based in East Asia, because F1 it too Euro centric.
I must admit I hadn't consideration the extra divider apparently attached to the rear uprights to stop tyre squirt into the diffuser (as opposed to the more conventional diffuser-attached dividers to stop tyre squirt into central sections of th ediffuser) -- that's a clever idea which hadn't occured to me!
[The current Indycar is most definitely not
designed for maximum downforce, that's why the diffuser angle is rather tiny, why there is no beam wing etc. While "wing cars" from F1 and Indy from the early 80's are from many generations ago and surprassed by more modern designs (i.e., time attack, hypercar) and so cannot be used for comparison of modern expectations.]
