McLaren’s Silverstone F1 Upgrades: F1 Team Leads the 2026 Development Race

Formula 1 arrives at Silverstone for the British Grand Prix with a battery of upgrades from several teams, and McLaren leads the changes among the top teams with modifications to the nose and floor of its MCL40. The world champions have introduced a new front brake duct that seeks to improve flow conditioning and gain downforce, while the revised floor aims to improve flow physics and overall efficiency.

Ferrari has also brought new features to Silverstone, the Italian team has updated the rear corner of the SF-26 with larger cooling inlet and outlet sections, an updated lower deflector and a reoptimized set of rear winglets, all with the aim of improving local load performance and cooling. Red Bull has only brought one upgrade this time, a revised rear corner with winglets on the rear bodywork to "improve load characteristics and stability."

Williams, in their home race, has debuted a new front wing geometry with updated profiles and endplate surfaces to generate an increase in local load combined with improved flow field interaction with downstream components. Racing Bulls has introduced a new floor corner and diffuser geometry to "generate more downforce and provide greater performance" as well as a new front deflector on the rear corner.

Haas, which has been overtaken by its rivals in development according to its driver Oliver Bearman, has brought two upgrades, comprehensively revised rear wing profiles and refined endplates with external protrusions to improve flow conditioning. Mercedes, Alpine and Audi have not presented upgrades for Silverstone, while Aston Martin, as is already known, is saving its new features for the Hungarian Grand Prix, where it has a major upgrade package planned.

Cadillac, which also brought a considerable package in Austria, will not bring new parts to Silverstone, the American team needs to solve its reliability problems before it can take advantage of its car's potential.

The Silverstone race is the ninth of the championship and will feature the sprint format, which adds an extra layer of complexity for teams debuting new parts. McLaren trusts that its upgrades will allow it to close the gap to Mercedes and Ferrari in the fight for the constructors' championship.

Williams hopes that its new front wing will help it score points in its home race, with Silverstone's high speed demands and the sprint format limiting practice time, the true effectiveness of these upgrades will be revealed quickly.

McLaren and Ferrari aim to close the gap to Mercedes, while Williams and Racing Bulls seek to strengthen their midfield positions on home soil.
