F1 Singapore GP: FIA allows cooling systems to protect drivers from extreme heat. The FIA has declared an extreme heat risk for the Singapore Grand Prix.

The FIA has declared an extreme heat risk ahead of the Singapore Grand Prix, authorizing the use of special cooling systems to help drivers cope with soaring temperatures. The measure, introduced this season as a precaution, comes after the controversy surrounding the Qatar GP in 2023, where several drivers suffered health problems due to extreme conditions.

Heat hazard declared

In the days leading up to the arrival of drivers and teams in Singapore, much of the discussion has focused on Marina Bay, known as one of the most demanding races of the season. The combination of mental and physical strain, close concrete walls, a twisty layout, heat, and humidity makes this Grand Prix one of the toughest challenges on the calendar.

To ensure the safety of the drivers, Race Director Rui Marques has declared an official “Heat Hazard,” after consulting weather forecasts that predict temperatures above 31°C for the entire race weekend. This recognition of extreme heat risk puts additional safety measures into effect.

Cooling systems to support the drivers

All teams will now be required to fit their cars with a driver cooling kit, designed to keep cockpit temperatures within safe limits and reduce health risks. These precautions were introduced following the Qatar GP 2023, where several drivers experienced physical distress during the race due to excessive heat inside the cars. Williams driver Logan Sargeant even had to retire from the race after feeling unwell.

Under the new system, drivers will be able to wear a special cooling vest that absorbs body heat and prevents excessive temperature spikes. The vest contains liquid cooled by a small air-conditioning unit integrated into the cockpit. Additionally, the FIA has authorized an extra air intake of up to 1000 mm², designed to direct airflow toward the driver and improve cooling efficiency.

These measures are expected to help prevent health issues linked to extreme conditions. The highest-risk day will be the race itself, with external temperatures forecast to climb as high as 33°C at Marina Bay.
