Austrian GP Faces Extreme Heat Conditions
Formula 1's governing body, the FIA, has officially categorized this weekend's Austrian Grand Prix as a 'heat-hazard' race. This designation is applied when track temperatures are projected to surpass 31 degrees Celsius during any session involving the cars. Forecasts for Sunday's 71-lap race, scheduled to commence at 14:00 BST, indicate temperatures could reach 33 degrees Celsius.
Cooling Kits and Regulations
The heat-hazard declaration permits drivers to utilize a specialized cooling kit. This system involves a fireproof top worn beneath their race overalls, through which cooled liquid, such as glycol, circulates. While the cooling kit is optional, drivers who opt against using it are required to carry an additional 5kg of ballast in their car. This regulation ensures that those choosing not to use the cooling system do not gain a competitive advantage.
This marks the first instance this year that an F1 race has been declared a heat hazard. The decision comes amidst a widespread heatwave affecting Europe, leading to record-breaking temperatures in numerous countries. The rule itself was first introduced last year, with the Singapore and US Grands Prix also running under this designation.
Driver Comfort and Cockpit Temperatures
Some drivers have previously expressed reservations about using the cooling kit, citing discomfort and concerns about the coolant depleting before the end of a race. If the coolant runs out, the liquid can reach the car's internal temperature, which is significantly higher than the ambient air. Temperatures within an F1 cockpit can exceed 40 degrees Celsius. Given that drivers wear multiple layers of fireproof clothing, a balaclava, and a helmet, the risk of overheating is a substantial safety and performance concern.
