What happened: McLaren was the lone Formula 1 team to register aerodynamic upgrades for the São Paulo Grand Prix, based on technical documents submitted to the FIA. The updates introduce a revised front wing, rear wing, beam wing, and floor furniture. Other competitors entered the weekend with unchanged specifications.

Why it matters: The development package represents McLaren's latest effort to optimize airflow and downforce across varied circuit layouts. Introducing multiple revisions during a sprint race weekend leaves the team with a single practice session to validate the parts on track.

What to watch: McLaren will evaluate the updated configuration during opening practice at Interlagos ahead of sprint qualifying.
