McLaren faces a technical challenge as it prepares for the 2027 Formula 1 regulations despite recent success. Lando Norris claimed victory at the São Paulo Grand Prix at Interlagos, where McLaren introduced upgrades that brought forward aerodynamic concepts planned for its 2027 car, including a new front wing, rear wing, beam wing, and updated floor.
