More @AlphaTauriF1 #AT03 detail. #F1
Front suspension is pushrod in contrast to RBR. Prob as it retains some 2021 features, such as the trackrod placement behind the axle line ImageImage
Front brake duct scoop is evident, with the 2022 demand for all air to pass in and out of the scoop ImageImage
Large and unusually placed panel on engine cover. Probably for a louver cooling panel option. ImageImage
Floor edge loaded with a single flap over the scrolled edge (all that the regs allows).
Diffuser kickline evident ImageImageImageImage
Front wing rising up over the nose tip reduces the angle of attack and therefore load created in the centre span. Provides more flow towards the underfloor Image

Porpoising. The cars can be seen to bounce up and down at speed.
This isn't new and not only related to big underfloor tunnels.
The car gets its downforce from the wings and underfloor. The ride at low speeds gives no problems.
#F1 Image
As speed increases the downforce increases too. This compresses the tyres and suspension.
As the underfloor gets closer to the ground, it works even better creating even more downforce
(this is ground effect).
Ride height continues to reduce with the aero load Image
This reaches a critical stage, where the ride height is too low and the airflow in the underfloor stalls.
This suddenly reduces downforce, the reduction in load uncompresses the tyre/suspension, lifting the car back up to a higher ride height Image

Ferrari F1-75 interesting car, cnt wait to see it under the skin, esp radiator and engine layout
Sidepod dimple appears to be about forming a curved edge to direct airflow toward the rear beam wing.
Bib vane visible in side iew

Here's the Williams super short ramped didepod.
There's a hole aligned with the crease in the sidepod front. Not as big as I would have predicted .
Also the super shallow nose and the clever tunnel fences.
Williams shorten the tunnel inlet roof, which allows the inlet fences to sit higher and influence airflow over as well as under the tunnels.
With the front brake scoops there's 3 inlets.
The outer inlet is blanked off, as it was cold at Silverstone, this suggests its a cooling inlet.
The grilled middle inlet probably is the main cooling inlet.
The inner inlet appears to pass around an inner duct?

#AT03 snap analysis
Back to conventional steering trackrod geometry and front axle position after the 2021 double bulkhead set up
#AT03
If this is accurate, they've gone for a forward front axle position. More space to the tunnel inlets, but shorter tunnels.

Front wings will all be different and quite a challenge for #F1 teams in 2022.
A front wing's primary job is to balance the downforce created by the rest of the car, i.e underfloor & rear wing. If you have a well balanced underfloor or small RW you only need a small FW.
The wings secondary role is to manage airflow downstream, this means Armitage directing and diverting airflow from key areas back aking the car, i.e front tyres, underfloor inlets, brakes and cooling inlets.
In 2022 the tunnel inlets are a major area to feed with clean air
In 2022 there's large regulatory box in which to fit the front wing. This gives a lot more freedom than in 2021.
You can run the wing high or low at different points across its span. Then chose how much of the remaining height within the box to create angle for downforce.
