F1 declares ‘heat hazard’ at Singapore Grand Prix, temperatures to hit 31 degrees Celsius
Regulations state drivers should be able to wear cooling vests, with some expected to shed 3kg in weight during the night race
This weekend’s Singapore Grand Prix has been declared an official Formula One “heat hazard” – the first time a new rule to help drivers stay cool has been invoked.
Race director Rui Marques told the teams of the regulation, which means drivers will be able to wear cooling vests, because ambient temperatures are expected to be 31 degrees Celsius (88 degrees Fahrenheit) or higher at “some point during the race”.
Singapore’s bumpy Marina Bay Street Circuit is one of the most physically demanding F1 races, where extremes of heat, humidity and weather all play a part.
Drivers can shed up to 3kg during the night race that often lasts the maximum two-hour race limit.
George Russell trialled the cooling vest, which is worn under the driver’s fireproof suit, at this year’s Bahrain Grand Prix.
“Not everybody finds the top comfortable, but I think some find it more comfortable than others, and of course over time you’ll be able to adjust it to your own preferences,” Russell said.
