Ahead of the Monza Grand Prix, McLaren has implemented vital alterations to its car, prioritising additions to the car’s downforce rather than designing an entirely new low-drag package. This decision was made after the poor performance of the MCL60 on the straights during the Spa-Francorchamps race, leaving drivers Lando Norris and Oscar Piastri struggling to compete with their racing counterparts.
Moving forward, the Woking-based squad aim to sidestep a similar situation at Monza, a competition where aerodynamic proficiency is key to competitiveness. Instead of creating an entirely new car design, McLaren has chosen to make significant adjustments to the existing lower downforce design, aiming to give their drivers an advantaged position on the straights.
The core modifications include a major rearrangement of the rear wing’s layout, significantly reducing drag and eliminating the bottom spoon-shaped portion. In an explainer to the FIA, McLaren confirmed the shipment of a “lower drag rear wing assembly with an offloaded mainplane and flap.” This is complemented by a reformed flap assembly that gives the team more trimming options, along with a modified rear wing endplate.
In addition to these significant changes in the rear, adjustments have been applied to the front section of the car. The front wing flap has been reduced to maintain a streamlined aerodynamic balance with the modified rear wing. Further modifications such as an altered front brake duct scoop have been made, designed to boost the aerodynamic load whilst avoiding any temperature-related issues.
World champions, Red Bull, also revised their approach ahead of Monza, choosing to trim the trailing edge flaps of both the front and rear wings to decrease drag. This is in contrast to Ferrari, who opted for a completely custom-made Monza low-drag wing package. Mercedes introduced a novel rear wing and beam wing, both designed with a smaller chord to minimise air resistance. Aston Martin‘s adjustments were notably minor, with a new rear wing flap being the only change.
Alfa Romeo, however, took a more extensive approach, overhauling both the main plane and the endplates of the rear wing. Efforts to make the airflow more efficient led to the revision of the upfront suspension geometry. The only team not making any adjustments is Haas, who chose to reuse previous configurations at Monza.
All focus now shifts to see how these modifications will impact the respective team’s performance during the Monza Grand Prix.
