The roll structure absorbed the initial impact as the car landed hard on the track upside down high speed
Then the other safety structures protected the Guanyu, the halo & the high sides/rear to the carbon-fiber survival cell. All of these are tested with extreme loads to be safe ImageImage
Pack your halos away safely tonight

FYI these are 3 load tests (in simplified terms) the roll structure is subject to. ImageImageImage

A break down of modern #F1 roll structure design...
Typically we think of roll hoops as a four legged 'hoop'. This creates mounts that are wide spaced, but relatively small. Creating points of high stress in an accident, where its bobded/bolted to the tub.

The blade format is quite different. Having a narrower closed structure, that widens at the base. Although the base mounting is narrower, there's a large contact point where its bonded to the monocoque to spread the load.

Although a conventional 'hoop' can also have a pointed shape and narrow mounting base. Similar to the blade concept and having similar structural properties.

Porpoising is an issue on most 2022 #F1 cars.
Red Bull have found their solution in a very clever & legal suspension innovation. So they can now run super close to the track.
With gas springs and inerters banned, they've exploited a non-newtonian fluid filled damper.

Thread:-
Everyone knows from home science experiments that non newtonian fluids are liquid, but become semi solid when a large force is applied to them. Like the Corn starch on a speaker experiment, even custard is a NNF!
I spoke to RBRs ex-Honda suspension engineer, Kesonyu-san about the system. The NNF filled damper does not affect normal suspension movement, but when the car starts to porpoise its non newtonian properties resist the bouncing. 'Porpoising Intervention Engineering' he calls it !

So we have now seen the @MercedesAMGF1 W13 #F1 Bahrain spec.
The extreme sloped sidepods are the key feature, that allow the aero to work despite their small size.
From ahead the jelly mould sidepods, do have inlets and side radiators.
To create the shape the side impact spars are detached from the sidepod and have their own shroud shared with the mirror mount.
Inside the radiators are repositioned slightly, but still in in an apparent conventional position. Also there's the usual coolers above the gearbox fed by the roll hoop.
Hot air exits through louvers and the high coke bottle exit.

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

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
