FIA Declares First 'Heat Hazard' for Singapore GP as Verstappen Tops Tight FP3

The declaration triggers mandatory cooling hardware with ballast to preserve weight parity, part of safety rules introduced after 2023 heat incidents.

Overview

  • Race director Rui Marques invoked Article 26.19 after an official forecast showed the Heat Index exceeding 31°C, marking the first use of F1’s heat‑hazard procedure.
  • All cars must be fitted with fluid‑pumped cooling system hardware; drivers may forgo the vest but must carry approximately 0.5kg of cockpit ballast to avoid a weight advantage.
  • Max Verstappen led final practice with a 1:30.148, just 0.017s ahead of Oscar Piastri, with George Russell third as the top five were covered by 0.089s.
  • Liam Lawson crashed again at Turn 7 to cause a red flag, forcing a rapid Racing Bulls rebuild ahead of tonight’s qualifying.
  • Lewis Hamilton has been summoned to the stewards for a potential red‑flag infringement in FP3 and could face a grid penalty depending on the ruling.
