FIA Declares Heat Hazard for Austrian GP as Temperatures Near 40°C

The FIA has declared a heat hazard for the Austrian Grand Prix as temperatures climb into the high 30s°C and track surfaces exceed 50°C. The ruling triggers mandatory cooling measures under F1's 2025 regulations, though drivers remain free to choose whether to wear cooling vests.

Why it matters:

The declaration marks the season's first test of F1's heat protocol, introduced after the brutal 2023 Qatar Grand Prix sent drivers to medical care. It forces teams to modify setups for cooling systems and extra weight, directly impacting strategy. The situation reignites debate over driver autonomy, with Max Verstappen arguing safety equipment should remain optional.

The details:

• The FIA invoked Article B1.5.10 after forecasts showed the Heat Index exceeding 31.0°C during Sunday's race, with highs of 38°C expected.
• Teams must fit advanced driver cooling systems, and the minimum car weight increases to cover the additional hardware.
• Drivers may decline cooling vests, but the car must still carry all other components plus 0.5kg of cockpit ballast to maintain weight parity.
• Similar hazards were declared last season in Singapore and Austin, though vest usage varied across the grid.
• Verstappen supports the optional approach, having called mandatory cooling gear "ridiculous" and emphasized personal choice.

What's next:

With Europe trapped under a lingering heat dome, the Spielberg weekend will be one of the season's most physically demanding races. Teams must integrate cooling hardware without sacrificing performance, while drivers battle extreme heat alongside on-track pressures.
