This is how the teams took the Spa tests

( – The totally different traits of the three sectors of the Spa-Francorchamps Formula 1 circuit imply that teams must compromise between velocity and downforce on the straights.

Red Bull has made some adjustments to the physique construction at Spa



It was no totally different to the new era of 2022 automobiles, however final weekend’s Belgian Grand Prix highlighted the major strengths of the Red Bull RB18 because it appeared fast on the straights with out shedding velocity in the two twisty sectors.

Red Bull additionally introduced some new elements to Belgium to enhance their efficiency. The greatest of those adjustments issues the transition of the physique between the aspect panels and the engine cowl. Also, the decrease management arm cowl of the rear suspension was redesigned.

The housing change ends in a extra luminous floor that may improve the underlying quantity (pink arrow, inset) whereas shifting the airflow outward. It’s a compromise between cooling and aerodynamic efficiency.

The adjustments made to the decrease arm are positively refined and don’t require structural adjustments.

Interestingly, the Red Bull has a notch on the underside of the housing above the diffuser as a result of it is so near the floor (small inset, blue arrow).

Another change the crew made to the rear-view mirrors was not featured in the automotive’s presentation documentation, because it is a minor change from a visible standpoint.

However, altering the exterior mirror end has some aerodynamic advantages. Extending the decrease a part of the skirt under the major mirror housing (which is additionally shortened, blue arrow) not solely adjustments the airflow conduct straight, but additionally as the airflow passes round the mirror housing.

Red Bull wasn’t nearly the new elements although, as there was one other attention-grabbing story: Verstappen and Perez wore totally different bodysuits in Belgium.

The Mexican opted for the spec launched first at Silverstone after which once more in Austria. The decrease a part of the physique has a Ferrari-like design resolution, with a tongue-like half reduce into the fringe of the ground and protruding from it.

Verstappen might have felt that he didn’t provide the identical stage of efficiency for his wants and didn’t make the most of the ground options all through the weekend.

A Ferrari with a brand new rear wing

The Ferrari had a brand new rear wing and rear wing with decrease downforce. However, after testing in the second free follow, it was determined to not use it over the weekend.

It’s a tactic we have seen Ferrari make use of when introducing downforce components. Instead, the Scuderia selected to enhance its efficiency in the second sector of the SPA, whereas additionally serving to with tire degradation throughout the race.

Despite the determination to not use the new rear wing, the adjustments are price noting as they may very well be used once more in future races.

The new specification takes up a lot much less area in the allowable field part and virtually fully eliminates the spoon-shaped lid design that was widespread resulting from the new rules resulting from the transition to the last board.

Mercedes and its undercarriage

Mercedes had been assured they may compete at the entrance for the Belgian Grand Prix after the summer season break, particularly when two title contenders Max Verstappen and Charles Leclerc had been pressured to start out additional up the area resulting from penalties.

However, it shortly grew to become clear that drivers would battle with a automotive that exhibited an excessive amount of drag on a observe that demanded aerodynamic effectivity.

In addition, in the first half of the season, the issues of heating the tires had been clearly seen. The Mercedes duo could not get sufficient warmth into the rubber to set a really quick lap.

The crew made extra adjustments for the Belgian Grand Prix. A revised entrance and rear wing was used, and different underbody tweaks had been made, together with consumption fenders and a wing wing.

The decrease finish was an space the place the crew was making an attempt to enhance its efficiency. The most up-to-date change is geared toward optimizing the relationship between the entrance a part of the physique and the edge wing.

Like a few of the different teams on the grid, Mercedes have now opted for a long-edged wing that spans the total size of the authorized space. It is curved upwards in the entrance space and a sickle formed half is utilized in the again space.

Both have been modified, with the up-facing part now having one information as a substitute of three (pink arrows).

The sickle-shaped space has been narrowed (see the yellow line) as the underbody subsequent to it has been reshaped, and the underbody and the rear of the rim wing have been reduce to create a tapered form in entrance of the rear wheel. Shared with 2021 guidelines (see inexperienced line).

Also, adjustments have been made to the entrance fences (blue arrow) to higher match the upstream and downstream adjustments.

Interestingly, Hamilton opted to not use the new physique in qualifying and the race, reverting to the outdated elements.

The crew additionally added triangular extensions (black arrow) to the prime of the halo, a design we have seen elsewhere, which little question assist direct airflow because it strikes round the engine cowl and aspect pillars.

Mercedes, which appears to have suffered extra from the barrier than its rivals, has certainly made adjustments to assist at the Spa-Francorchamps circuit.

But as a substitute of introducing a wholly new aspect, the designers improved the efficiency of the wing by making adjustments to the wing tip, finish plate and prime flap. The W13 plate is designed in order that the groove in the wing tip could be modified to go well with the desired load of the wing.

An answer with downward power was utilized to the higher cowl



In this case, the crew selected to fully fill the void (pink arrow above), a trick we noticed earlier in the season in the Alps to regulate the energy of the vortex popping out of the wing tip.

The crew additionally examined a pull-down function on the higher lid, the place the lid was reduce (pink arrows). However, this feature was excluded because it didn’t present the mandatory stability between excessive speeds in the first and final sectors and low velocity in the second sector.

What’s new at Alpine?

Alpine continues to push ahead with its A522 and has additional optimized the bundle. For the Belgian Grand Prix, the crew additional modified the entrance of the underbody and its transition to the outermost grid. As you possibly can see in the image, the backside of the new design is pressed inward in the shoulder space.

Marked in inexperienced: adjustments known as “Floor Fence”.



This not solely impacts the exterior air move and the relation to the grid, but additionally determines the passage of the air move by way of the tunnel below the ground, which adjustments the connection to the grids once they open in the direction of the fringe of the ground.

The crew has additionally made adjustments to the design of the rear brake pipe as they proceed to search for methods to stability cooling and aerodynamic necessities.

Many teams selected to position the consumption on the within the brake hose (blue arrow) as a substitute of a devoted consumption bucket (pink arrow), an answer we see at the entrance of the automotive.

The new resolution collects the airflow that passes between the grille and the sidewall of the tire and directs it to varied channels that join inside the tire, a few of which have been modified as a part of the replace.

The absence of an air pit signifies that the fins on the outdoors of the grille are much less obstructed and could be tweaked later to additional enhance efficiency.

New rear wing on Alfa Romeo

For the challenges of the Spa-Francorchamps circuit, Alfa Romeo developed a brand new rear wing to cut back downforce and subsequently drag.

Alfa Romeo additionally had a brand new rear wing at Spa



The wing is a typical design with a scoop form that permits for a clean transition to the finish plate in the rule.

The greatest change from the typical design, nevertheless, issues the form of the higher plate transition, with the plate being reduce diagonally from the entrance part to the wing tip.

The crew additionally had one in every of their common wing specs available, a shortened trailing fringe of the prime flap, probably as a backup if the first selection did not work out as anticipated.

However, to allow the DRS mechanism, the crew wanted to maintain the middle part of the wing at its regular top.
