Upgrades are few and far between in Austin, but Mercedes is among two F1 teams to deliver new parts.
Mercedes and Haas are the only F1 teams introducing upgrades at the United States Grand Prix, as the teams shift focus towards the 2026 season regulations.

On the other hand, Haas has introduced a comprehensive package for the VF-25, featuring new floor body, floor fences, floor edges, sidepod inlets, and a rear corner winglet. Esteban Ocon will test the new parts during practice in Austin, with a second set available for Oliver Bearman. The majority of teams are now directing their efforts towards the significant changes expected in 2026, with only minor upgrades being introduced.
