Red Bull has made an adjustment to the front brake duct for the Portuguese GP, with an extra vane added to the upper section of the inlet to help direct the airflow where it needs to go inside the brake duct.

Red Bull made a significant change to the design of the sidepod deflector array for the third race of the season, with the forwardmost vertical element split into two sections, whilst it now meets with the floor rather than being mounted above it. The Venetian blind-like arrangement has also been adjusted.

The AlphaTauri AT02’s diffuser has been modified in the outer section. The shape of the outer wall, and the Gurney-like tabs that surround it, have all had their shape subtly adjusted to help improve flow out of the rear corner and limit the damage created by the wake shed from the tyre alongside.

A look under the engine cover of the Mercedes W12, note the much bigger inlet plenum on the power unit this year that’s resulted in the bodywork needing a blister to cover it.

The front end of the AlphaTauri AT02 with the ‘S’-duct panel installed shows how the airflow from the nose enters the panel above the chassis indent and is channeled to the outlet on the slope of the chassis.

There’s plenty going on in this image of the Red Bull RB16B with the engine cover removed we can see the saddle style cooler mounted above the power unit. Without the brake drum installed we can see the pipework that carries cool air to the caliper.

A look at the front brake duct on the Mercedes W12, note the wire added to the inlet to prevent discarded rubber and debris collecting inside the tract and reducing cooling performance.

The front brake duct of the W12 from the other angle, which shows off the fence and the various fins used to help redirect the airflow as it passes by. Also note the small inlets tangled up amongst the fins, which are used to capture more airflow that can then be redistributed outboard the assembly.

The Mercedes W12’s front wing for comparison which is much more loaded in terms of angle. Also note the positioning of the adjuster when compared with the McLaren, with the distribution of what is mobile and immobile very different between the two.

The McLaren MCL35M brake duct has two curved channels carved into the drum that are used to encourage the air to follow in order it’s emitted out of the wheel face in a more aerodynamically beneficial way.

The forward floor and sidepod deflector region on the Mercedes W12, both of which are crucial in dealing with the wake created by the front wheel assembly ahead and setting up structures that improve performance at the rear of the car.

They’ve been a feature on the rear wheels of the Mercedes for some years now but these large fins help to control the temperature of the rear tyres, as they act like a heatsink.

A great shot of the W12’s endplate which shows the amount of contouring needed to be made to include the thicker upwash strikes (the regulations govern the thickness of the endplate, of which the strikes must also adhere to).

At the front of the VF21 we find the brake assembly before the ductwork is applied, given us an idea of how the airflow collected by the main inlet is channeled to the various elements that make up the assembly.

The VF21 front brake assembly with the ductwork attached shows us how some of the work being done by the inlet is aerodynamic in nature and not just used to cool the brakes.

With the drum mounted you can imagine the void that’s created between the two surfaces and allows airflow to be carried from the inlet to the outer face of the wheel, where it mitigates some of the inefficiencies created by the wake being generated by the tyre.
