F1 2022 tech review: How Alpine unleashed grid's most aggressive update push (2023)

Listen to this article

Making the most of improved resources at Enstone, and a much-improved power unit from Viry-Chatillon, the team ended up being one of the surprises of the campaign.

That was partly the result of it adopting an aggressive development push compared to other teams – with it bringing updates to almost every race of the season rather than staggering them like rivals.

Alpine made a change to the location of its caliper for 2022, moving it to the front of the assembly, rather than the rear.

This was likely a decision driven by aerodynamic intent, rather than mechanical, with the design of the caliper enclosure also meticulously designed to ensure that the heat being generated by the disc had a means to pass through.

Alpine kicked off its development programme with a swift change to the sidepod's rear profile, altering the shape of the downward-sloping section of the ramp quite significantly.
The more haunched outer shoulder also resulted in a deeper inner channel section to not only help define the airflow's passage but also have more of an influence over the wake being generated by the rear tyre too.

The team also debuted a new lower-downforce rear wing in Bahrain, setting out the team's stall when compared to many of its competitors, with the Anglo-French outfit seemingly able to trim the car more at a given circuit.

The rear wing was retained for the Saudi Arabian Grand Prix but the team took a novel approach to the endplate design, opting not to use a cutout in the upper, rear corner. This would have the effect of altering the downforce and drag characteristics of the wing and was a design that would find its way onto the Mercedes W13 later in the season too.

The optimisation process continued at pace in Australia when the team altered the shape of the outer floor fence (dotted white line) and the ramped section thereafter (red arrow).

A great overview of the A522 at Imola, showing the changes made to the sidepods and floor over the course of the first few races.

Close up of the sidepods and floor, which had been tweaked once more for Imola, noting the floor stay which the team had added and allowed them to reduce the overall weight of the floor.

More changes also ensued with the floor's edge (red arrow) and the outer floor fence (dotted yellow line), as the team looked to slowly introduce changes that enhanced performance.

A shot of the bib wing on the A522 at the Miami Grand Prix that the team had added, having seen others use similar solutions in the opening phase of the season.

A rare peek under the A522 at the Miami Grand Prix gives us a clear view of the floor fences, the contouring of the underfloor tunnels and diffuser transition.

Changes were made to the front wing at the Spanish Grand Prix, with inspiration taken from Haas on the design of the endplate's leading edge (yellow line). This obviously also had an impact on the geometry of the surface thereafter too (red arrow).

A higher downforce rear wing also arrived, albeit the design continued to have the same design hallmarks of the other specifications already seen.

A look at the wing in question, with the DRS activated, gives us a view of the metal snubbers mounted to the underside of the wing to prevent it going too far when it's closed.

Alpine A522 beam wing comparison

Alpine not only had a new low downforce rear wing specification at its disposal for the Azerbaijan Grand Prix, but it also made the switch to the stacked bi-plane style beam wing layout that Red Bull had been using since the start of the season.

A new sidepod inlet also arrived for Baku, with the inlet moved forward quite considerably when compared with the old specification. This not only had an impact on flow into the sidepods but also enlarged the undercut to improve flow around them.

More optimisation for the beam wing arrived in Canada, as the team switched back to the more conventional layout for that circuit but altered the shape of the elements (dotted lines).

An overhaul of the sidepod bodywork arrived in time for Silverstone, with the crevice introduced earlier in the season extended much further forward.

A great view of the bib region of the car without the bodywork in place. Plenty of equipment packed in here, whilst the scythe-shaped metal stay's roots can be traced back to when the team ran under the Lotus name.

Alpine A522 'Ice Skate'

Poking out from underneath the floor we can see the 'Ice Skate' solution that was adopted by Alpine, having been first used on the Red Bull RB18 but also finding its way onto other cars too.

More changes to the beam wing for the Hungarian Grand Prix as the team offloaded the outer edges to reduce downforce (dotted yellow lines).

The team changed its rear brake duct layout for the Belgian Grand Prix, deleting the external scoop to clear a path towards the rearward winglets (red arrow) and opened up an inlet in between the fence and tyre's sidewall.

The outermost floor fence was also optimised once more, with the ramped section rolled over to soften the transition both on the upper and lower surface.

The team looked to balance the car for the Dutch Grand Prix with changes to the front wing and beam wing.

The floor optimisations continued for the Singapore Grand Prix, as the edge was reprofiled and extra metal inserted to help with flexion.

This continued in Austin, as the team introduced a solution seen elsewhere on the grid, whereby a flap could be found protruding out from under the floor from a cutout. This was connected to the ice skate.

The flap moved relative to the skate, rather than the floor, and helped reduce the impact of tyre squirt on the diffuser's performance.
