Overview
- McLaren introduced a four-part aerodynamic package on Friday that includes a redesigned front wing, a new rear wing assembly, an updated beam wing and floor changes.
- The front wing shows major architectural shifts: the nose now mounts to the second flap, the pylons attach to the middle element and the mainplane and flap chords have been altered to redirect airflow toward the floor.
- McLaren was the only constructor to declare updates for the São Paulo race, making the upgrade a rare, isolated late-season test of a concept the team expects to carry into its 2027 launch specification.
- Initial running in Friday practice produced encouraging lap‑time signs and positive feedback from Lando Norris, but team staff warned the package could worsen the MCL40’s tricky drivability and requires further analysis.
- The test at bumpy Interlagos targets underfloor flow conditioning that could both help McLaren’s immediate bid to reclaim third in the Constructors’ Championship and shape the aerodynamic foundation of next year’s car.
