The Fédération Internationale de l’Automobile (FIA) has listed the technical upgrades brought by several Formula 1 teams ahead of the British Grand Prix, which will be held on July 5, at Silverstone.

With Silverstone known for its high-speed corners and heavy aerodynamic demands, several teams used the race weekend to fine-tune their cars, while others opted to stay with existing packages.

McLaren led the front-running teams in terms of updates. The team introduced changes to the front corner and floor area of the MCL40, including a new front brake duct designed to improve airflow and add aerodynamic load. It also revised the floor board to improve flow behavior and overall efficiency.

Ferrari brought an updated rear corner to Silverstone, with larger cooling inlet and outlet sections, an updated lower deflector, and a reworked rearward winglet cluster. The changes were aimed at improving local aerodynamic load while addressing cooling needs.

Red Bull, which already introduced a bigger upgrade package in Austria, submitted a smaller update for the British Grand Prix. The team revised the cascade wings in the rear wheel bodywork winglets to improve load characteristics and stability.

Racing Bulls also made changes to the floor corner and diffuser geometry, with the goal of generating more load and improving performance. The team also updated the forward deflector geometry at the rear corner to help condition airflow and improve floor performance.

Haas brought one of the more visible updates to Silverstone, focusing on the rear wing and rear wing endplate to improve overall aerodynamic performance.

According to the FIA, the team revised the flap geometry to help the car generate more load while keeping a high level of efficiency across different operating conditions. The endplates were also updated with localized protrusions designed to promote upwash and add more load at the rear of the car.

Williams, meanwhile, introduced a new front wing geometry for its home race. The update featured revised profiles and endplate surfaces to increase local loading and improve the way airflow interacts with downstream components.

Mercedes, Alpine, Audi, Aston Martin, and Cadillac did not submit new upgrades for the Silverstone weekend.

The upgrade list highlights how teams continue to search for small but critical gains in a tightly contested development race. At a circuit like Silverstone, even minor changes to airflow, cooling, and rear stability can influence a car’s balance through fast corners and long race stints.
