The International Automobile Federation issued its first 'heat danger' warning in its history for the Formula 1 Singapore Grand Prix.

High temperatures, up to 31°C, have led to the imposition of new rules that allow drivers to equip their cars with cooling devices. The cooling system consists of pumping a liquid through a series of tubes, but its use is not mandatory. To ensure weight equality of the cars, additional weight is added in case a driver chooses not to use the device.
