McLaren has introduced a comprehensive upgrade package for the Brazilian Grand Prix at Interlagos, aiming to strengthen their competitive position in the 2026 Formula 1 season. The sweeping modifications were revealed ahead of the São Paulo race weekend, marking a significant development push by the British team.
The upgrade package encompasses aerodynamic and mechanical changes designed to improve performance at the challenging Interlagos circuit. McLaren's technical team has focused on optimizing the car's characteristics for the anti-clockwise layout and variable weather conditions typical of the Brazilian venue.
Team representatives indicated the upgrades have been in development for several months and represent the most substantial revision to the MCL38 specification since the summer break. The modifications are expected to address specific weaknesses identified during recent race weekends.
