Heat Hazard Declared for the Austrian Grand Prix

Core Event
On 25 June 2026 the FIA announced a heat-hazard status for the Austrian Grand Prix at the Red Bull Ring in Spielberg. Race Director Rui Marques cited official weather forecasts predicting ambient temperatures above 31 °C (88 °F) during the weekend. Under Article B1.5.10 of the FIA Formula 1 Sporting Regulations, the declaration obliges every team to install a driver-cooling system (liquid-cooled vest) while allowing drivers to forgo the vest by adding ballast to maintain weight parity.
Background of the Heat-Hazard Protocol
The rule was created after the 2023 Qatar Grand Prix, where several drivers required medical attention for heat-related illness. It entered the 2025 regulations and was first applied at the Singapore Grand Prix in October 2025, then at the United States Grand Prix in Austin. The Austrian event marks the first heat-hazard race of the 2026 season and the third such designation in Formula 1 history.
Key Figures and Teams
- FIA – governing body, represented by Race Director Rui Marques.
- Drivers – Red Bull’s Isack Hadjar, McLaren’s Oscar Piastri, Red Bull’s Max Verstappen, Alpine’s Pierre Gasly, Mercedes’ Kimi Antonelli, Ferrari’s Lewis Hamilton, and Sergio Perez (Cadillac).
- Teams – Red Bull Racing, McLaren, Mercedes, Ferrari, Alpine, and others fielding the optional cooling equipment.
Forecasts and Technical Requirements
- Forecasts ranged from 31–32 °C (AP) to 34 °C (PlanetF1) and 36–38 °C (F1I, Jang). Track surface temperatures were expected to exceed 50 °C.
- The cooling vest circulates chilled liquid through tubing beneath fire-proof overalls.
- If a driver declines the vest, 5 kg of ballast is added to the car (some sources note a 0.5 kg ballast for the vest-weight difference).
- Cockpit temperatures can rise above 40 °C, sometimes reaching 50 °C, despite ambient conditions.
Why the Declaration Matters
The protocol aims to protect drivers from heat stress that can impair concentration and physical performance, while preserving competitive fairness by equalising vehicle weight. It also influences race strategy, as teams balance the comfort benefits of the vest against the performance impact of added ballast.
Official Statements & Responses
The FIA released a formal notice: “*In accordance with Article B1.5.10… a Heat Hazard is declared*.” Race Director Marques confirmed the activation based on the forecast. Drivers gave mixed responses: Isack Hadjar said the vest is uncomfortable and only useful for a short period; Oscar Piastri highlighted his personal heat-training regimen; Max Verstappen reiterated that the vest should remain optional.
Criticism & Opposition
Several drivers expressed discomfort with the system. Hadjar described the tubes as “too many” and noted the cooling effect lasts “about 10 minutes.” Verstappen argued that mandatory vests would be “ridiculous” and emphasized driver choice. Concerns also include coolant depletion before race end, leaving the liquid at car temperature.
On-the-Ground Preparations
Piastri built a “hot-weather training setup” using portable heaters and an exercise bike in a small bathroom to simulate race-day heat. Perez, noting his Mexican background, said the temperatures are “pretty average” for him but will still wear the vest.
Conflicting Reports & Gaps
Sources differ on the exact forecast: some list a maximum of 32 °C, others predict 38 °C on race day. Ballast requirements are reported as 5 kg in most articles, while one source mentions 0.5 kg to offset vest weight. No data were provided on how many drivers will actually use the vest or on the performance impact of the added weight.
Verbatim Quotes
- “I think the moments where you have zero kph in the car, they are definitely the worst,” — Isack Hadjar, Red Bull Racing
- “You can cause yourself a lot of discomfort, a lot of pain by doing that. I do that for the benefit of my performance. Not for pleasure, that’s for sure.” — Oscar Piastri, McLaren
- “I just think it should be an option – that you can choose for yourself whether you want to wear it or not,” — Max Verstappen, Red Bull Racing
- “It makes me laugh that all the Europeans are concerned about this level of heat.” — Sergio Perez, Cadillac
- “In accordance with Article B1.5.10 of the FIA F1 Regulations, having received a forecast from the Official Weather Service predicting that the Heat Index will be greater than 31.0 °C at some time during the Race at this Competition, a Heat Hazard is declared,” — FIA statement, Race Director Rui Marques
What’s Next
The heat-hazard rules will be in effect for practice, qualifying and the race on 27 June. Teams must decide whether to fit the cooling vest or carry ballast, a choice that could influence driver performance and championship points as the season progresses toward its summer midpoint.
