McLaren surpassed even its personal pre-season expectations in 2024, taking its first Components 1 constructors’ championship title for 26 years.
While the crew clearly had a few main waypoints in its improvement cycle that improved the final working envelope of the MCL38, a standout function of its marketing campaign was the way it honed its automobile to the various circuit traits.
These updates largely centered across the beam wing and rear wing, with a big proportion of its improvement funds expended there.
This resulted within the crew having eight totally different rear wing options, while its beam wing choices prolonged out additional, with 14 totally different iterations put into play.
To offer some context to those numbers, Pink Bull launched simply 5 totally different rear wing options and had 4 beam wing variants, Mercedes had 5 totally different beam wing and rear wing designs (albeit not launched in tandem), while Ferrari matched its rival with the variety of rear wing updates however had simply eight beam wing choices at its disposal too.
Breaking that down additional, whereas Ferrari is the closest when it comes to the quantity of choices declared within the FIA automobile presentation paperwork, the ‘updates’ it set forth for Suzuka and Monza weren’t truly new and have been the truth is carried over from 2023 as a substitute.

Made to suit
From a numbers standpoint, it’s clear that groups have to make use of the identical options at a number of venues, with just a few outliers designed and constructed to deal with particular duties.
Nonetheless, one space that has been improved with this era of laws is the reintroduction of the beam wing.
The power to make use of one or two components inside the allowable field area has given designers a large number of choices when it comes to design.
They’ll load or unload the weather throughout their span and supply a more cost effective technique of tuning the downforce and drag generated by the higher rear wing components.
So, let’s check out the varied options that McLaren used through the course of 2024, given that there have been extra races than specs at its disposal, with some races clearly not as absolutely optimised as others.

On this occasion, the tip part was trimmed throughout its nook (dotted yellow line, Saudi Arabia inset), which has an affect on the tip vortex and alters the downforce and drag generated by the meeting.
It’s clear that this was all the time a plan when the design was conceived, as there’s a metallic insert used within the nook of the tip part that permits it to be trimmed with out exposing the inside core of the element.
On condition that this rear wing wasn’t thought of new within the automobile presentation paperwork however had a big modification, we’ll seek advice from it as Variant 2.5 any further.

Rear wing Variant 6 had been within the pool of choices because the Belgian Grand Prix and had solely seen the sunshine of day briefly at Monza earlier than being swapped out for a higher-downforce association.
However, given the calls for of the road circuit, the crew opted to pair it with a suitably low-drag beam wing.

The eighth variant rear wing was used on the season finale in Abu Dhabi and was paired with the single-element beam wing, reasonably than the higher-downforce bi-plane-style beam wing association utilized in Brazil.

As you may see, McLaren clearly retired a few of its earlier designs because it moved by way of the season, with new variants of its medium-high and medium-low downforce options approaching stream through the tail finish of the season.
Nonetheless, the crew additionally had extra outlier options at its disposal too, which allowed it to be slightly extra selective at every venue. Completely different preparations have been examined throughout free observe periods earlier than selections have been finally made about which variants offered the very best stability between qualifying and the race.

That is additionally important once we contemplate how the crew has to stability the event of its 2026 automobile, which all squads can start work on from 1 January.
However the early phrase from McLaren is that it’s not planning simply an evolutionary step for 2025 because it weapons for each titles.
