The Woking-based group has overtly acknowledged that aero effectivity has been one in all its core weaknesses this yr – and this has typically manifested itself in an absence of prime velocity.
The squad has additionally been aware that that is an space the place Crimson Bull has been significantly robust, particularly when its DRS is in use.
However having understood the place Crimson Bull’s DRS benefit comes from – which pertains to the higher balancing of drag ranges between its beam and rear wing behind the automobile – McLaren has been pushing to search out features on this space too.
For the Las Vegas occasion, McLaren has made the leap in adopting one of many key facets that’s understood to be behind Crimson Bull’s edge – which is in having a single beam wing.
Using a single beam wing, which works at the side of a extra highly effective essential aircraft rear wing component, implies that Crimson Bull’s DRS features are a lot higher when the flap is open in comparison with different groups that run with double beam wings.
However most groups have discovered themselves unable to trim again on their beam wing preparations as a result of, whereas that will enhance drag ranges, it additionally means a lack of downforce that they nonetheless want to assist enhance stability on the rear of the automobile.
McLaren’s transfer means that it has confidence it could now do away with its secondary beam wing with out it impacting its automobile efficiency or driver confidence.

In addition to going to a single beam wing association for Las Vegas, McLaren has additionally launched a reprofiled rear wing flap that works at the side of it to assist enhance prime velocity.
Talking earlier this yr, McLaren group principal Andrea Stella acknowledged that the shift of beam wing/rear wing relationship was one thing that Crimson Bull had put to sensible use for some time
“They appear to have pursued this idea for a while,” defined Stella, when requested by Autosport if the beam wing strategy was key to Crimson Bull’s DRS benefit.
“So, I believe they might be taking some benefit from having numerous expertise in growing this sort of configuration. I believe this has now turn out to be obvious over time.
“We’re, I believe all groups now, making an attempt to see what is feasible to take advantage of by growing this sort of route.”
Alpine is one other group that has made adjustments to its beam wing for Las Vegas, with its slat eliminated and the decrease rear wing profile being reprofiled to scale back drag.
The Enstone-based squad has additionally modified the trim of its inboard entrance wing section to assist obtain a greater aero steadiness with the brand new association on the rear.
It has additional moved to scale back drag by eradicating the rear brake drum higher flicks.
