Ferrari also opted for the kiel probe rake behind the front tyres early on in the session.

In this side view of the Alpine A522 note how flat the car is being run, a feature we’ll see up and down the grid from now on but one that seems at odds to what we’re used to from a visual perspective.

AlphaTauri also had kiel probe rakes mounted behind the front wheels as it looks to correlate the real-world behaviour of the airflow under these new regulations with their simulation tools.

Ferrari appear to be leaving only the three forward-most cooling gills open on its sidepods while the temperatures are much lower in the morning session.

A look back from the front of the Ferrari F1-75’s sidepods, with their convex, hot tub-like upper surface.

An overview of the Red Bull RB18’s sidepods and floor, note the section in the middle of the floor which is raised and angled to alter the course of the airflow.

The Williams mechanics adjust the front wing flap angle as Albon comes into the pit box. Also note the sensor mounted on the mainplane, just ahead of the nose tip.

A great shot of the Williams FW44 as Alex Albon exits the garage – note the upper portion of the sidepods inlet feeds directly out of an outlet on the sidepods rear shoulder. Meanwhile, there’s a detached triangular-shaped floor scroll and the arc-ed floor section to be aware of too.

A closeup of the Aston Martin AMR22’s nose tip, which merges with the second element of the front wing. Also note the metal inlays on the leading edge of the wing upon which the stays are connected to it and then the mainplane ahead.

A look underneath the brake drum cover at the rear of the W13 reveals some of the design details used to keep things cool, including the brake disc and bell and the internal pipework routing.

A shot of the Ferrari F1-75 with the vanity panel removed allows us to see some of the inboard suspension elements, including the heave damper.

A look at the Mercedes W13’s chassis bulkhead, the carbon skeleton frame on the front of it used to protect the elements housed inside, the front brake duct and deflector winglets without the wheel and tyre fitted and the aerodynamically shaped fairings that cover the front suspension and steering arms.

McLaren has kiel probe rakes front and rear, with the forwardmost assembly fitted behind the front wheels, while the rearward one is fitted right at the rear of the car to measure the performance of the diffuser in its outer edge, whilst also capturing the inboard tyre wake data.

The floor edge detail on the Haas VF-22 which features numerous up and down turned sections. Also note how far the detached shark fin section is raised above the louvred cooling outlet on the engine covers spine.

Rear-end shot of the Ferrari F1-75 – note the rear wing pillars, which are not a swan-neck design like much of the rest of the grid. Also note the thickness difference in the upper and lower suspension element fairings.

Williams FW44 rear detail

A peek inside the Williams FW44, as the covers have been taken off – note that the team has moved much more of their cooling to the cars centreline, which has resulted in a larger airbox intake but allowed them to dramatically reduce the size of their sidepods.

Looking over the top of the Mercedes W13’s sidepods shows just how angled the outermost wing mirror stay is.

That same mirror stay can be seen here on the shoulder of the Mercedes W13’s sidepods, along with the strakes protruding from the front edge of the underfloor tunnel and the wavy floor edge.

Mercedes trialled another cooling gill panel on the W13, having already tried a smaller panel ahead of this one in the afternoon session on the first day of the test.
