George Russell is set to line up from the very back of the grid for the Singapore Grand Prix on Sunday after his team elects to fit a fresh power unit, a move that pushes him beyond his allotted four engines for the season and triggers a mandatory penalty. The decision comes on the heels of a dramatic failure in the Bahrain Grand Prix, where the Briton’s power unit gave way while he was running third, forcing an early retirement. His teammate, Kimi Antonelli, finished second in that race, extending his lead over Russell in the Drivers' Championship to 84 points with seven rounds still to run. The new power unit will be installed for the Singapore event, meaning Russell will exceed the season limit and be relegated to the rear of the starting grid.
Mercedes team principal Toto Wolff confirmed the situation, describing it as "particularly frustrating given the way George drove last weekend and the result he deserved to be fighting for." Wolff added that such setbacks are part of Formula 1 and that the team’s immediate focus is to give Russell the best possible machinery and the chance to claw his way back through the field. "We need to maximise this final Sprint weekend of the year, keep learning, and score the strongest result we can with both cars," Wolff said.
He highlighted that the Singapore circuit, with its tight, twisty layout, will serve as a crucial test of the team's understanding and resilience after a very difficult weekend in Malaysia. "Malaysia was obviously a very difficult weekend for us.
We have spent the days since then working hard to understand why our performance was not where it should have been. We have identified several areas we need to investigate further, but F1 doesn't offer simple answers and we need more evidence before drawing firm conclusions. Singapore gives us an immediate opportunity to continue that work.
The characteristics of the circuit are very different and that will help us build a clearer picture of where we are. That is why we will evaluate both the latest update package and our previous specification across the weekend to ensure we fully understand the direction we need to take," Wolff explained.
Russell was originally slated to receive a new, upgraded power unit at the United States Grand Prix later in the month. That upgrade is part of the FIA's ADUO (Additional Development and Upgrade Opportunities) programme, which allows teams to introduce significant engine improvements outside the normal development cycle. Mercedes have argued that the governing body’s ranking of their power unit below Red Bull’s is unfair, insisting that the Silver Arrows, who dominate the Constructors' Championship, already possess the most powerful engine on the grid.
In a surprising turn, the upgraded unit could be fast‑tracked for Singapore, preventing further penalties for Russell later in the season if additional new parts are required. Both Mercedes drivers have endured power‑unit woes this year.
Antonelli, for example, had to start from the back at the Italian Grand Prix but fought his way up from 19th to claim victory, demonstrating the team’s capacity to overcome adversity when the car finally clicks. The Marina Bay Street Circuit in Singapore is notorious for being one of the toughest tracks on the calendar for overtaking, especially compared with high‑speed venues like Monza where passing is relatively easy. Because Singapore is a Sprint weekend, Russell’s grid penalty applies only to the main Grand Prix on Sunday; the Sprint race on Saturday will see him start from his qualifying position. Sky Sports analyst Craig Slater warned that a back‑of‑the‑grid start in Singapore is a nightmare scenario for any driver.
"This is not the place where you want to take a grid penalty because it is difficult to overtake in Singapore. The reality is Russell is going to find it very difficult to get anywhere near double‑digit points in the race itself.
It will be hard for him to get into the top five. Eighty‑four points back, that is absolutely the final straw for this title bid," Slater said. He added that Russell needs a string of victories to stay in contention and to send a clear message to the 2027 season that he remains a viable championship contender capable of beating the rising star Antonelli. Mercedes introduced a major aerodynamic upgrade at the Malaysian Grand Prix – their biggest package since the Canadian Grand Prix in May – but were still comfortably outpaced by Red Bull.
Max Verstappen turned pole position into a win, leaving Wolff to label the Malaysian weekend as "the worst of the season," chiefly because of Russell’s retirement, which he called "not acceptable." Deputy team principal Bradley Lord explained that a combination of the new updates, track temperature, and the circuit surface created a complex interaction that prevented the car from finding its usual balance, especially in the slow corners where drivers were forced to keep the throttle open, exacerbating tyre temperature issues. He described the problem as a "3D" challenge that the team is currently dissecting both at the factory and on‑track in Singapore. Looking ahead, the team’s schedule for the Singapore weekend is packed. Thursday will feature a drivers' press conference at 11 am, followed by a paddock uncut session at 2 pm.
Friday’s agenda includes practice at 9 am (with the session officially starting at 9:30 am), a team bosses’ press conference at 11:30 am, and Sprint qualifying at 1 pm (starting at 1:30 pm). Saturday will see the Sprint race build‑up at 9 am, the Sprint itself at 10 am, and then the build‑up to the main Grand Prix qualifying at 1 pm, with qualifying commencing at 2 pm.
The day will conclude with Ted’s Qualifying Notebook at 4 pm. Sunday’s program begins with a Grand Prix build‑up at 11:30 am, the race itself at 1 pm, post‑race reaction at 3 pm, and Ted’s Notebook at 4 pm. All sessions will also be available on Sky Sports Main Event.
In summary, Russell faces a daunting challenge in Singapore, starting from the back of the grid on a circuit where overtaking is notoriously hard. Mercedes, meanwhile, are using the weekend as a laboratory to assess both their latest aerodynamic package and the fast‑tracked upgraded power unit. Their goal is to extract as much performance as possible, learn from the data, and finish the season on a positive note, giving Russell the best possible chance to rebound in the remaining races and keep his championship hopes alive.
