Max Verstappen’s suspicion that one thing has “gone incorrect” with Purple Bull’s RB20 explains why the Method 1 group was experimenting with some older specification components at Zandvoort final weekend.
In an try and resolve what has made its 2024 challenger “tougher to drive”, Verstappen and team-mate Sergio Perez break up flooring configurations in a bid to assist the squad collect knowledge.
However, whereas efforts are specializing in understanding if the foremost flooring change made at Imola was the set off for its latest struggles in opposition to McLaren and Mercedes, that has not stopped it persevering with to attempt to eke out positive factors from different areas of the automotive.
Purple Bull arrived at Zandvoort with quite a few small tweaks for the RB20, because the high-downforce sidepod and engine cowl association launched on the Hungarian Grand Prix returned – having been taken off for high-speed Spa.
There was a slight tweak, although, with the group having modified the dimensions of the rear cooling outlet to higher serve the calls for of the Zandvoort circuit.
This narrower association will present further versatility in its cooling set-up over the approaching races, with the group additionally in a position to swap the cooling panels on the aspect of the engine cowl to higher swimsuit its necessities too.
The brand new inlet is equally sized to the one used with its different engine cowl association, however the change in bodywork additionally leads to the shops that have been lower into the rear quarter panel being eliminated.
As well as, there have been additionally a brand new set of mirror stays and fins across the cockpit on the RB20, because the group appears to be like to make some small tweaks to the airflow’s behaviour because it tracks down the automotive.
This was possible in response to the arrival of the brand new sidepod and engine cowl bodywork first seen in Hungary and used once more at Zandvoort.

There are a number of variations to the association too, with the horizontal mirror keep now not merged on to the mirror housing (white arrow), which has additionally been modified to swimsuit the vertical baffle that now resides between the 2 surfaces and certain sheds a stronger vortex downstream over the sidepod.
The outer vertical keep has additionally been modified (pink arrow), with a shorter association taking the place of the tail-like resolution beforehand employed, which can alter how the airflow across the sidepod’s shoulder area behaves.
In the meantime, the canard-style winglet mounted on the aspect of the halo has been deleted and a vertical fin now resides atop the half-crescent higher sidepod inlet (blue arrow).
The winglet is kinked within the higher half with the intention to swimsuit the contours of the halo fairing alongside too.
The drivers additionally opted to run completely different downforce ranges on their vehicles at Zandvoort, with Verstappen choosing the higher-downforce rear wing configuration, like he had run in Hungary.
Perez, nevertheless, opted for much less downforce, much like how they ran each vehicles at Spa.

New entrance wing at Haas
Haas had quite a few new parts for the VF-24 on the Dutch Grand Prix because it appears to be like to enhance movement on the entrance of the automotive with the intention to unlock extra efficiency additional downstream.
The brand new components have been solely raced by Nico Hulkenberg, but it surely was a scrappy weekend for the group with incidents and combined climate that made it tough to collect a lot suggestions.
In making the change, Haas has taken an holistic overview to the automotive’s entrance finish aerodynamics.
The nostril, entrance wing and entrance suspension fairings have all been altered in tandem to leverage the efficiency that may be garnered from each other.
The nostril has now been prolonged to satisfy with the mainplane, somewhat than the second ingredient, with the tip form tweaked.
There may be additionally a extra rounded profile chosen so that it really works extra harmoniously with the central part of the wing.
This in flip has allowed the group to change the flap distribution, with narrower static inboard higher flaps beside the nostril.
This enables for wider moveable sections, each of which have much less chord top than their counterparts and extra curvature throughout their span.
The slot hole separator brackets have additionally been reconfigured throughout the whole wing, with much less wanted between the mainplane and second ingredient as a result of nostril now being related to them.
Moreover, the aerodynamically formed brackets often discovered between the higher two parts have been exchanged for extra historically formed horseshoe-style brackets.
The kind of modifications Haas has made with these updates are extremely vital with this technology of vehicles, as defined by principal aerodynamicist Simone Benelli.
“The primary subject, on the inboard aspect, is to try to enhance the movement high quality for the entrance movement consumption and the sidepod undercut, as a result of there’s nothing underneath the chassis,” he stated.
“Every thing you create by way of loss near the entrance wing is free to journey with out a lot management. So you must management it upstream with the entrance wing.
“Then, outboard, we’re persevering with with our improvement, which is consistently making an attempt to enhance the underside tail wake. It’s this which is answerable for some inconsistency in sure instances on entrance load, in low velocity, medium velocity, and crosswinds generally.”
