The short version
- Round 17 is the final sprint weekend of 2026.
- George Russell, last year’s winner, starts Sunday’s race from the back after taking a fifth power unit. Kimi Antonelli leads him by 84 points and cannot clinch the title this weekend.
- The FIA says it has found the cause of Sepang’s software failure. Nothing new is planned for Singapore, and a further wet-weather update is due before Austin.
Mercedes: a penalty and a question
Mercedes were quickest in two of three practice sessions at Sepang, then lost their pace in qualifying. Deputy team principal Bradley Lord blamed a mix of the new upgrade, track temperature and surface. He said the drivers were on the throttle in slow corners, which hurt tyre temperatures. Marina Bay has plenty of slow corners.
Russell’s lap-50 retirement was a mechanical failure on the power unit side, Lord said, and the root cause is still unknown. The replacement is Russell’s fifth unit of the year, beyond the four-unit allocation, so he starts Sunday from the back of the grid.
Antonelli leads 320 points to 236. Singapore offers 33 per driver (eight for the sprint, 25 for the race), which is not enough to settle anything. The earliest he can clinch is the US Grand Prix on 25 October. Even then he would need to outscore Russell by at least 42 points across the two weekends, out of a maximum possible swing of 58. A long shot, but not a closed door.
What the FIA found at Sepang
The FIA’s review is complete. It blames a bug in the power unit software that limits electrical power around the lap. In the wet a 250kW reduction applies, and some cars running low revs in certain sectors lost more power than intended and could not recover it. That is how a formation lap became a car park. The FIA says it found the fault within minutes and sent teams a revised configuration during the red flag. It rejects the suggestion the code was never tested, saying it ran in simulation and in first practice at the Belgian and Dutch Grands Prix. Whether a bug that sailed through those sessions counts as tested is a question for the philosophers.
For Singapore no further changes are planned. If it rains, cars revert to what reports call the Malaysia configuration, though they don’t say whether that means the original or the patched version. A further wet-weather update is due before the US Grand Prix.
The forecast is less settled than the software. There is chance of rain at 30% on Friday and 40% on Saturday and Sunday. Humidity could reach 83% at the start of the race. Weather forecasts in F1 are proving less reliable than the Aston Martins at this stage. Things could change.
Ferrari: a podium, a stall and noise upstairs
Lewis Hamilton’s third place was his first podium since Silverstone, and it followed a scare. His car stopped on the straight during the formation lap and had to be restarted. Ferrari still can’t explain why, and Fred Vasseur said on Sunday he had no clear answer. Ferrari are second on 405 points, 151 behind Mercedes.
The leadership story has not moved. Ferrari said on 29 September that it had made its choices and had full confidence in Vasseur. Hamilton said on 1 October that “there are also people above” the team principal, and Vasseur called his relationship with Benedetto Vigna and John Elkann a very good one. No change has been announced as of Thursday.
Red Bull and McLaren
Max Verstappen arrives with Red Bull Ford’s first win and first pole, level with Lando Norris on 188 points. Red Bull sit 18 behind McLaren in the constructors’ table. Singapore remains a gap on his record: four podiums, three of them second places, and no win.
McLaren concede the MCL40 may not suit Marina Bay’s slow 90-degree corners, and say the latest upgrade hasn’t delivered in Baku or Sepang. They did win here in 2024 and clinched last year’s constructors’ title at this race.
The circuit and the tyres
Marina Bay is 4.927km, with 19 corners and 62 laps, and Hamilton holds the lap record: 1:33.808, set last year. Every edition up to and including 2023 had at least one Safety Car, 24 deployments in total, but 2024 and 2025 had none. Russell won last year’s race from pole without one, so the old certainty has been downgraded to a tendency.
Pirelli bring the C3, C4 and C5 (hard, medium and soft) again and expect a one-stop to be the preferred strategy. The soft may get a look from more than one team on Sunday. With a single practice hour, the sprint is where teams will learn how it behaves.
Midfield
| Team | Points |
|---|---|
| Racing Bulls | 90 |
| Alpine | 68 |
| Haas | 27 |
| Audi | 17 |
| Williams | 12 |
| Aston Martin | 7 |
| Cadillac | 0 |
Racing Bulls lead Alpine by 22 after Alpine failed to score at Sepang. Fernando Alonso’s eighth place there was Aston Martin’s best result of a difficult season and cut the gap to Williams to five points. Cadillac remain the only team without a point, though the sprint pays down to eighth, which gives the back of the grid a second chance this weekend.
Sepang showed what happens when everything that can go wrong does. Marina Bay, with its humidity, one practice hour and a sprint thrown in, is a decent venue for a rematch. Bring a towel.
