Mercedes driver George Russell set the pace in the only practice session for the Singapore Grand Prix, leading Charles Leclerc of Ferrari by 0.198 seconds. A late lap from Leclerc secured him second place, breaking an all-British top three.

Lando Norris of McLaren finished third, 0.273 seconds off Russell's pace, while Lewis Hamilton, also from Ferrari, was fourth, 0.499 seconds behind. The top five was rounded out by McLaren's Oscar Piastri, all utilizing soft-compound tyres. In sixth, Max Verstappen of Red Bull was the fastest on medium tyres, clocking in 0.732 seconds off the pace.

Key results from the session included:

• George Russell (Mercedes) - Fastest
• Charles Leclerc (Ferrari) - 2nd
• Lando Norris (McLaren) - 3rd
• Lewis Hamilton (Ferrari) - 4th
• Oscar Piastri (McLaren) - 5th
• Max Verstappen (Red Bull) - 6th (medium tyres)

Russell faces a challenging weekend as he will start from the back due to a penalty for exceeding engine parts, following an engine failure during the Bahrain Grand Prix. He is also running a previous car specification, while teammate Kimi Antonelli tests a new aerodynamic package.

As the session progressed, Isack Hadjar (Red Bull) took eighth, followed by Pierre Gasly of Alpine and Liam Lawson from Racing Bulls in the top ten. Meanwhile, Fernando Alonso of Aston Martin briefly entered the top ten but finished 14th.

The event occurs under air-quality warnings due to haze from wildfires in Indonesia, urging local citizens to limit outdoor activities.
