F1 tech review: Alpine drifts despite inventive solutions

While the team continued to develop solutions that could later be found on its competitors machines, those great ideas weren’t cohesive enough to prevent them from being marooned on a points island of their own in the middle of the midfield pack.

Let’s take a look at some of the A523’s finer details and how the team developed their package throughout the course of 2023…

An overview of the A523’s front wing from pre-season testing, which featured flaps with a similar distribution across their span. We’re also treated to a view of some of the inboard suspension elements with the vanity panel left adrift.

Without the front brake drum in place we’re able to see that the caliper is placed in the forward position on the A523. Teardrop-shaped holes in the fairing allow airflow/heat to pass through the assembly.

Alpine’s rear wing at the Saudi Arabian Grand Prix featured a narrow central section that was deeper than the outboard sections of the wing.

A large cooling gill panel was utilised on the side of the engine cover to help manage temperatures.

A close up of the rear corner on the A523 shows us the stepped lower edge employed on their rear brake duct winglet, whilst a bi-plane style beam wing arrangement was also in use. The beam wing’s slatted upper element sat further forward and under the exhaust’s tailpipe, whilst the lower element sat further back and was mounted on the side of the crash structure.

In Azerbaijan the team trimmed a notch out of the front wing’s upper flap at the inboard end to help balance the car front-to-rear given its choices at the rear of the car.

The lower downforce rear wing assembly used by Alpine in Azerbaijan featured a mainplane and top flap design that featured leading edges pushed back from their comparable position as they met the endplate.

Alpine A523 rear detail

A more gradual spoon-shaped rear wing was employed at the Canadian Grand Prix as the team looked to match the demands of the circuit. It was also the first outing for their open-ended tip section design.

In order to alter the behaviour of the rear wing’s tip vortex, Alpine introduced an open-ended flap solution, whereby the flap extended across the wings span, providing an extra shedding surface and altering the cutout in the rear corner of the endplate.

Alpine made the switch to a tapered flap solution at the British Grand Prix, altering the interaction with the endplate (inset, right) and likely providing more of a desirable outwash effect. The team also toyed with various upper flap designs to cater for the downforce demands of different circuits, such as the wavy trailing edge first seen in Hungary, inset.

Tufts were added to the beam wing at the Italian Grand Prix as the team looked to gather some real world data regarding the performance of their car.

Sensors placed on the floor ahead of the rear tyre to gather data for the team and help them correlate their simulation tools and the information gathered from the real-world environment.
