And whereas its rivals just about steered away from any upgrades in Brazil for what was the third race of a triple-header, it was attention-grabbing that McLaren elected to deliver a brand new rear and beam wing association.
McLaren’s strategy on this entrance has been fascinating this yr, as it’s head and shoulders forward of its rivals when it comes to the sheer scale of improvement that has been undertaken on this space.
The group has launched seven completely different rear wing configurations to deal with the completely different downforce and drag traits that every venue calls for.
New choices had been added to the pool in Saudi Arabia, Imola, Monaco, Nice Britain, Belgium, the Netherlands and now Brazil.
In fact, it might all be for nothing if the designs didn’t mix nicely with the beam wing resolution that can be fitted to the meeting.
That’s the reason we’ve even seen it arrive with a number of beam wing choices alongside every new rear wing specification to trim the automotive accordingly.

This factor varieties extra of a V-shaped profile the place it tapers outward and upwards from the deeper central part.
The forefront, seen in the principle picture, can be extra steeply rolled than its closest kin inside the household of options obtainable.
Notably, the tip part of the rear wing additionally differs from different designs on this downforce vary, with a squarer profile, just like the one used on its highest downforce possibility.
These design variations are doubtless the results of a suitable effectivity trade-off between two of its different specs, because the discount in peak throughout the mainplane’s span gives the required downforce and drag for the circuit traits, while additionally offering extra of a profit when DRS is deployed.
In the meantime, the form of the lowermost beam wing factor has a reverse tapering within the central part to discreetly mirror the geometry of the mainplane above.
The distinction in beam wing format to the corresponding rear wing choice might be seen within the comparability above.
However whereas McLaren ran its new rear wing for dash qualifying and the dash on Saturday, when it got here to the trickier moist circumstances posed by qualifying and the race it opted for its increased downforce association.
