As we approach the hottest Grand Prix events of the season, Formula 1 is preparing to take a major step forward in managing extreme conditions with an innovative cooling system set to debut in 2025.
Inspired by episodes of intense heat, such as the 2023 Qatar Grand Prix, this new driver cooling system could revolutionize driver comfort and safety. Let’s break down how this technology works, its current development, and why it’s crucial for the future of our favorite sport.

A new driver cooling system for extreme heat
The FIA’s new regulations propose an integrated cooling device within the drivers’ racing suits, designed to circulate cooled liquid through tubing. This concept was tested at the 2024 Mexico Grand Prix using a prototype powered by an ice block to lower the liquid’s temperature. Weighing about 11 lbs, the system’s weight might be adjusted as it evolves. To offset this added mass, the 2025 regulations propose increasing the cars’ minimum weight, currently set at 1,759 lbs. Additionally, teams will have the freedom to develop their own versions of the system, meaning innovation will extend to this area with tailored solutions for each team, with weight in focus to save as much as possible.
Rigorous testing for optimal deployment in competition
During tests, one driver reported a noticeable improvement in thermal comfort, though the limited test duration didn’t allow for comprehensive data collection. Initially, the FIA considered incorporating a simplified air conditioning system, but integration issues in the F1 car led to its abandonment in favor of the liquid-cooling approach. Teams might also opt for alternative solutions, such as fans delivering fresh air directly into the suit. However, strict rules govern the materials used to ensure safety. For instance, only air, water, and certain approved mixtures are allowed, while dry ice is strictly prohibited for safety reasons.
Why is this innovation essential?
The extreme heat of the 2023 Qatar Grand Prix underscored the challenges of temperatures well above 90°F, with cockpit heat reaching 120°F. During that race, multiple drivers struggled: Logan Sargeant retired due to heatstroke, Esteban Ocon raced despite nausea, and Lance Stroll briefly lost consciousness. These extreme incidents prompted the FIA to take swift action to prevent similar occurrences in the future. While some drivers, like Lewis Hamilton, believe such a system isn’t essential, it represents a significant step forward for the sport. With positive feedback from the driver community, this device could become a standard, especially for events known as the most grueling, such as Singapore or future editions of the Qatar Grand Prix.
This article explores recent technological advancements in Formula 1 aimed at enhancing driver safety and comfort under extreme heat conditions. From ongoing tests to future prospects, this innovation promises to transform the sport while highlighting the importance of driver feedback in shaping its evolution.
