If you could post a quote or a screenshot of the section where they switch between new parts, it's a pay-walled article.CjC wrote: ↑28 Aug 2024, 09:50This is said article:

The main part of the upgrade was a new high-downforce specification of rear wing and beam wing. “This wing gives us general efficiency gains, a bit more downforce, better slow-speed performance and a better DRS gain,” McLaren’s chief designer Rob Marshall explains.
Whereas the previous high-downforce wing flap featured a completely straight trailing edge, this one incorporates the central vee indentation of the lower downforce family. That surrenders only a small amount of total downforce from the section, which is shielded by the DRS mechanism (and so less effective), to give a drag reduction even when not in DRS mode
The wing still features the separate outboard winglet sections which taper the downforce away at the outboard ends for a useful drag reduction. But the downward sweep of the lower part of these winglets is now much more pronounced and appears to integrate more closely with the geometry of the top of the endplates.
The beam wing has been reshaped to feed the airflow in a way appropriate to the reshaped main plane of the main wing.
The downforce and drag of a rear wing are determined by the shape and area of the main plane upper and lower surfaces, the flap design and geometry and how they all interact throughout the speed range.
Balancing out all the compromises inherent in making it more efficient – which has been the whole target of this development – is a hugely complex mathematical challenge taking up a lot of personnel and resource time. That explains the long lead time and the big gap between major upgrades.
The accompanying changes – more efficient front brake ducts, a re-alignment of the brackets on the floor edges, re-aligned sheaths for the front and rear suspension arms – were minor in their effect.

On various resources where several pictures are superimposed on a photo, the authors often make mistakes. Some kind of general inattention, or indifference. When I saw the new rear wing on Friday, I was surprised when in comparisons they singled out the wing that had already been used in Barcelona. However, the fact that this is precisely the Barcelona wing, I have already carefully studied only this evening, comparing different options that have already been used earlier this season.Vanja #66 wrote: ↑28 Aug 2024, 11:29Oh boy, they mixed everything up with that illustration... The "Zandvoort" rear wing spec on that illustration is the one they tried out in FP1 (with Piastri I think), which is actually Singapore 23 spec and also used in Barcelona 24. Beam wing on the illustration is also older spec from Barcelona 24 (and even before that, I think) while the new spec sees a smaller lower element. Here's what both cars ran in the race

different from spa spec
Ah it seems like they have come up with an optimized low DF wing as well, perhaps an extension of the package prepared for Zandvort.
Very interesting. Good job, team!
In 2022 Alfa Romeo had triangular cut on their flap tips
Is that the first time those Winglets on the DRS flap droop like that, or just the angle. Or is it actually cut away as Vanja suggests? The fact I would still expect to see the black outline on the winglets, but can't, suggest to me that part of the winglet has just drooped behind and lower than is visible.
