F1 issues first-ever ‘heat hazard’ warning for Singapore Grand Prix
Singapore GP drivers offered cooling vests as temperatures soar
- F1's governing body has issued a first-ever "heat hazard" warning for this weekend's Singapore Grand Prix, with temperatures expected to reach a humid 31C.
- New regulations allow drivers the option to fit a cooling vest to their cars, which circulates liquid to help manage high cockpit temperatures.
- The cooling system is not mandatory, but cars whose drivers opt not to use it will have 0.5kg of ballast added to ensure equal vehicle weight across the field.
- Mercedes driver George Russell, who suffered "borderline heatstroke" at last year's Singapore race, previously used a similar vest in Bahrain and found it effective in extreme heat.
- The new cooling device was implemented following the "dangerous" 2023 Qatar Grand Prix, where numerous drivers encountered health problems due to humid conditions.
