Mercedes has a raft of new parts available for the Belgian GP but here’s a look at the bargeboard and deflector region, both of which have seen substantial optimisation by the team.

We noted the three additional fins on the floor of the Mercedes W11 ahead of the rear tyres in our gallery yesterday but the wider-angle shots from today have revealed another three fins have been added midway along the floor too.

McLaren has added another weapon to its growing arsenal in Belgium, with a revised set of sidepod deflectors installed on the MCL35, having already made numerous revisions to other areas of the car in recent races. The main deflector panels remain largely unchanged but a row of three flaps have been added beneath the main assembly to help tidy up flow in that region.

McLaren has designed and manufactured a 2021-specification floor to test at the Belgian GP in order to collect some real world data on the lower level of downforce that the configuration is expected to yield.

The spoon-shaped rear wing fitted to Max Verstappen’s RB16 to lower downforce and drag around the Spa-Francorchamps circuit. Also note the vertical cooling inlets beside the cockpit/halo are in use again this weekend.

Ferrari has a very low downforce rear wing package this weekend, as it looks to take as much drag off the car as possible. Leclerc running with the newer front wing specification at this point too.

A new lower downforce rear wing for Renault this weekend as it looks to shed some of the drag for the long straights in sector 1.

Alfa Romeo is looking to do a similar thing but trying to achieve this with a spoon-shaped wing which has a much deeper central section to retain more of that downforce.

Alfa briefly had an even lower downforce rear wing bolted onto the rear of Kimi Raikkonen’s C39 during FP1, with the team likely looking to make sure it’s working as anticipated ahead of the Italian GP, whilst also seeing if they could get the balance needed through sector 2 to use it this weekend.

Kiel probe arrays mounted in behind the front wheels on Alex Albon’s RB16 help Red Bull to collect airflow data about the car, especially the turbulence created by the front wheels.

Another low downforce rear wing, this time on the Racing Point RP20, with the team also spraying flo-viz paint on the rear of the assembly to get visual confirmation that the airflow is acting as predicted beforehand. Also note the larger pods on the side of the airbox which enclose thermal imaging cameras that are used to monitor all four tyres and build a better picture of how the tyres are heated throughout the course of a lap and stint.

Haas has a new lower downforce rear wing for the Belgian GP too, with much shallower mainplane and top flap, with the latter having a bow-tie shape to the trailing edge, as the surface gently curves into the two Vs at the slot gap separators.

The low downforce rear wing favoured by McLaren this weekend has a shallower mainplane and top flap. Also note, similarly to Racing Point, McLaren also use additional thermal imaging cameras during Free Practice to capture tyre temperature data.

The low downforce rear wing on the AlphaTauri not only features shallow wing elements but also note how the upper flap has been cut into a V in the centre and at the outer ends, reducing the drag created.

Williams with a lower downforce rear wing, which albeit not as trimmed out as some rivals is quite different from their usual configuration. Note also how it’s painted flo-viz on the rear of the wing to get visual confirmation that the airflow is doing as anticipated.

A great shot of the Haas VF20’s rear end, showing the diffuser, the rear wing endplate design that is now also a feature of the RB16, and the lower downforce rear wing for the Belgian GP.

Close up of the Ferrari SF1000 as Charles Leclerc rounds turn 1, note how little downforce the team has dialled in with its rear wing, as both elements are both nearly laid flat.
