Overview

• Red Bull fitted a new micro-aero floor mod only to Max Verstappen’s RB21 for Friday’s opening practice at the British GP, repositioning floor fences and re-profiling surfaces to enhance downforce and stability.
• McLaren declared a revised floor geometry and introduced a new rear corner inlet aimed at boosting local airflow and brake cooling, according to FIA pre-round disclosures.
• Aston Martin and Haas each brought four separate underfloor and bodywork updates targeting improved ground effect efficiency and cornering stability at Silverstone.
• Alpine remained the sole team in the bottom-six constructors not to introduce any upgrades for the British Grand Prix.
• Red Bull intends to continue RB21 developments through the upcoming summer break before shifting full resources to its 2026 regulation-compliant car.
