The FIA has confirmed significant updates to the Formula 1 regulations for the 2025 season, focusing on driver cooling systems and adjustments to DRS (Drag Reduction System) usage. These changes, ratified at the World Motor Sport Council meeting in Rwanda, aim to enhance safety and performance in high-temperature races while refining aerodynamics for better racing dynamics.
Driver Cooling Systems Introduced for Heat Hazard Races
A key highlight of the 2025 rule updates is the introduction of mandatory driver cooling systems for races classified as “heat hazard” events. If the FIA‘s official weather radar predicts temperatures above 30.5°C, or if the race director preemptively declares a heat hazard, all teams will be required to implement cooling measures for drivers.
To accommodate the additional weight of these systems, the minimum car weight will increase by 5kg for the entire race weekend. This adjustment ensures teams can prioritize driver safety without compromising car performance.
DRS Regulations Tightened for 2025
The FIA has also refined DRS specifications to prevent innovative yet controversial aerodynamic tricks, such as McLaren’s “mini-DRS” solution seen in the 2024 season.
The gap range for rear wing slots has been adjusted, reducing the minimum to 9.4mm (previously 10mm) and the maximum to 13mm (previously 15mm). The upper limit for the DRS-open position remains at 85mm. Additionally, new guidelines mandate only two DRS positions, ensuring precise reversion of the rear wing to its original state post-DRS activation.
Looking Ahead: Aero Innovations for 2026
Beyond 2025, the FIA has outlined detailed active aerodynamic regulations for the 2026 season. These include:
- Active Front Wings: Two flaps can transition between modes for cornering and straight-line performance, restricted by physical stops to ensure compliance.
- Rear Wing Configurations: Teams may use up to three elements, with flexibility for two-element designs, ensuring diverse aerodynamic strategies.
- Enhanced Floor Design: The floor sidewall now includes winglet and fence bodywork to boost downforce.
Additional changes involve improved bodywork around wheels, including deflectors and debris guards, paired with updated wheel drum regulations to optimize safety and aerodynamics.
The FIA’s comprehensive approach to these regulations reflects its commitment to fostering innovation while ensuring safety and fair competition across the grid. These adjustments set the stage for a thrilling evolution of Formula 1 in 2025 and beyond.
