Williams FW44 front wing detail

A look underneath the Williams FW44’s front wing which is far less complex than we’re used to, as teams can no longer used strakes or overtly complex flap geometries. Also note the camera mounted to the FOM camera pod.

The AlphaTauri AT03 has a floor cutout midway along its length where a flapped section is mounted above the floor in its place.

A nice overview of the Alpine A522 from the side, note the floor strakes protruding out the front corner of the floor and the cutout and rolled section thereafter.

The AlphaTauri AT03 with green flo-viz paint applied gives a general idea of some of the flow streams as it makes its way down the car.

Red Bull also joined in with the paint party, albeit their use of flo-viz was a little less liberal and more localised.

Alpine probably thought that by using blue flo-viz we might not notice it against its livery, but we did. Here it is daubed all over the car’s rear end, as Fernando Alonso kicks up some gravel on the track.

More flo-viz on the Red Bull RB18 towards the end of the first day of testing, albeit more targeted than some of their rivals in order that it can understand specific flow structures.

Red Bull also changed one of the panels on the RB18’s sidepods and engine cover during the afternoon session to one with a succession of cooling gills.

Mercedes also switched out a panel beside the cockpit which incorporated some additional cooling gills.

Rear view of the Red Bull RB18 which shows not only the diffuser, rear brake duct winglets and their uniquely stacked beam wing design, it also shows the size of the upper cooling outlet.

Comparatively, the McLaren MCL36’s cooling outlet looks a little wider.

The Ferrari F1-75 has a much smaller rear cooling outlet but this is due to the cooling gills it has pressed into the sidepods upper surface.

By comparison the Aston Martin AMR22’s rear cooling outlet is even smaller but it also has the cooling gills atop the sidepod to help reject the heat being generated within.

Alpine has the rear cooling outlet situated lower down but it’s also supplemented by the cutaway and louvred section in the engine cover’s spine. It was running with an asymmetric cooling gill layout at this point, with the left-hand side of the car open, while the right was closed.

The Red Bull RB18’s sidepods feature a displaced leading-edge arrangement, with the lower lip housed much further forward to artificially increase the size of the inlet, while also serving to act as a flow conditioner for the sidepod’s undercut. Also note the multi-element mirror housing design.

The Aston Martin AMR22 was also fitted with laser ride-height sensors on the edge of the floor.

The top edge of the Alpine A522’s front wing differs from its competitors, with a notch taken out the surface.

A look at the Alpine A522’s rear wing with the relatively flat leading edge mainplane, rather than the spoon-shaped one seen elsewhere. Also note the rear wing mounting pillar connects directly to the DRS actuator pod, rather than to the mainplane, which should give a small boost, aerodynamically, as there’s cleaner flow to the underside of the wing.

Red Bull’s rear wing also features just a single mounting pillar that’s connected to the DRS actuator pod, rather than the leading edge of the mainplane.

Here’s the DRS actuator pod assembly from the rear on the Red Bull RB18, which looks very different to its predecessor.

An extreme closeup of the driver cooling hole in the Red Bull RB18’s nose tip, which appears to be part of an interchangeable panel so that it can run without the hole if necessary.

The mainplane’s leading edge is arched up and exposes the underside of the nose on the AlphaTauri AT03.

In contrast the mainplane on the Red Bull RB18 dips down and the nose is connected to the second flap in the sequence.

Conversely, Aston Martin has a high central mainplane with the nose fixed to the second front wing element.

Ferrari has yet another layout, with a dipped mainplane, whilst the nose stretches all the way to the leading edge.

AlphaTauri placed a pitot tube array in the mouth of their airbox to collect some data and make sure it’s performing as expected.

The McLaren MCL36 doused in flo-viz paint in order that the team can get visual confirmation of what aero surfaces are working as expected and where gains can be made.
