McLaren launched a brand new rear wing at System 1’s Belgian Grand Prix that indicators a shift in idea course and strikes it nearer to what Crimson Bull is doing.
The wing is just not solely the bottom downforce variant that the Woking-based squad has run on its MCL38 to this point this yr, however is believed to be the primary of a brand new suite of choices with this concept that will probably be rolled out for various monitor sorts as they seem on the calendar.
We often categorise the rear wings offered by groups into three easy classes: low, medium and excessive downforce variants.
However inevitably, given the number of the circuits on the calendar, there is a bit more to it than that, with some adaptability baked into how every of these preparations may be configured.
Groups now are more and more balancing out the downforce/drag of their rear wings with their beam wing answer too, as these can assist fine-tune the automotive steadiness to hit the candy spot.
Moreover, the chord size of the higher flap, whether or not there’s a Gurney flap utilized to the trailing fringe of the flap or not, plus the form of the tip part and endplate cutout, are all technique of modifying a given wing to go well with particular calls for.
Shut examination of the McLaren rear wing launched in Belgium reveals it carries some new DNA compared with the household of options beforehand utilised this season.
The obvious of those is the transition zone between the mainplane and endplate, as a a lot squarer radius has been sought.
There are a number of ramifications to this, provided that quite a few circulation constructions converge on the juncture. The form of the cutout and the semi-detached tip part have additionally been modified as a consequence.
This decrease downforce variant of this new design lineage clearly takes up a lot much less house throughout the allowable field area, however it does so throughout the whole span of the wing.
This ends in a extra uniform form throughout the width of the wing, fairly than displaying the deeper spoon-shaped profile that’s usually related to this regulatory period.
The higher flap has additionally been redesigned in live performance with these adjustments, not solely so that it really works appropriately in a closed state, but in addition in an effort to enhance efficiency when DRS is in operation.
It is a clear step change in philosophy from the previous and seems to maneuver McLaren a lot nearer to the strategy Crimson Bull has product of in search of a much bigger DRS swap, one thing which the Milton Keynes-based squad has loved all through the present floor impact period.
McLaren has additionally remodelled the V-shaped notch across the higher flap’s centreline that it had already tweaked this season. The notch has been suitably sized to the higher flap, while being thoughtful of the Gurney flap utilized to the trailing edge.

In the meantime, the upwashing swage line on the skin of the endplate’s face, which has been a part of McLaren’s design language for a while now, has additionally been eliminated.
This triggered some adjustments to the beam wing and the rear brake duct winglets too, as all of those work in tandem given the shut atmosphere they inhabit.
