McLaren's Brazil upgrades raise questions for 2027 car

Lando Norris won the São Paulo Grand Prix, a result that highlighted how competitive McLaren's MCL40 can be at Interlagos. The track's medium-speed corners suited the car, reducing the impact of its well-known drag deficit on straight-line speed.

McLaren introduced a new front wing, rear wing, beam wing and updated floor in Brazil, aimed at generating more downforce and improving aerodynamic balance. The team has effectively brought forward part of the conceptual shift planned for its 2027 car.

The 2027 regulations will lengthen the wheelbase by roughly 15cm, which will significantly change load distribution and the aerodynamic maps. That raises the question of how much of the Brazil package can carry over to the new car.
