Overview

• Fernando Alonso set a 1:31.116 to top first practice, 0.150 seconds ahead of Charles Leclerc with Max Verstappen third and Lewis Hamilton fourth, as Oscar Piastri and Lando Norris placed fifth and sixth.
• Williams confirmed Alex Albon suffered a rear‑brake hardware failure that caused a fire and ended his session, with the team confident of repairs in time for FP2.
• FP1 at Marina Bay ran in low‑grip, dusty daylight conditions that produced multiple lock‑ups and are not representative of qualifying or the race under floodlights.
• The FIA designated the weekend a heat hazard for the first time, allowing drivers to forgo cooling‑vest equipment if 0.5kg of cockpit ballast is fitted to compensate.
• McLaren can clinch the constructors’ championship in Singapore with 13 points, as Verstappen’s recent wins in Monza and Baku keep him in the broader title conversation behind leader Piastri.
