Exciting New F1 Rules: Cooling & Wing Changes for 2025 GP

Discover how the new F1 rules on cooling systems and wing adjustments will impact the 2025 British Grand Prix. Learn what changes to expect and how teams will adapt at Silverstone.

New F1 Rules: Cooling System Changes for Driver Safety

One of the key changes introduced for the 2025 British Grand Prix relates to the new driver cooling systems. After heat-related issues during the 2023 Qatar Grand Prix, the FIA has mandated that when ambient temperatures exceed 31°C, a “Heat Hazard” condition will trigger the use of a cooling vest for drivers. This vest circulates chilled fluid to help keep the driver’s body temperature in check. Teams must install the system, which includes a fire-resistant shirt, tubing, a pump, and a thermal store.

Impact on Car Weight

To accommodate the cooling vest, the minimum car weight will increase by 5kg during races, and 2kg during practice and qualifying sessions. Although drivers have the option to opt-out of wearing the vest, they must carry an additional 500g ballast to maintain compliance with the weight regulations. These changes will undoubtedly affect the aerodynamics and balance of the car, with teams needing to carefully manage the additional weight during races, particularly at Silverstone, where weather conditions can vary dramatically.

How New F1 Wing Changes Will Impact Front Wing Flexibility in 2025

Another significant change concerns the front wing flexibility regulations. Starting from the Spanish Grand Prix, the permissible deflection under a 1kN load has been reduced from 15mm to 10mm, and the deflection under a 6kg load on the front wing flap is now limited to 3mm, down from the previous 5mm. These adjustments are designed to curb aerodynamic advantages that certain teams, like McLaren, may have previously gained through flexible wings.

Impact on Aerodynamics and Performance

The reduced flexibility limits will directly affect aerodynamic performance and handling. Teams will need to adapt their front wing designs, and the impact will be most noticeable during practice sessions at Silverstone, where teams will have the opportunity to fine-tune their setups. The changes may also influence car balance, forcing teams to rethink their setups to ensure optimal performance while staying within the new regulations.
