George Russell is poised to start from the back of the grid at the Singapore Grand Prix on October 11 due to a power unit change following an engine failure during the Bahrain Grand Prix. This setback significantly impacts his championship aspirations as he trails team-mate Kimi Antonelli by 84 points in the Drivers' Championship with only seven races remaining.

Russell's retirement in Bahrain occurred while he was running third, forcing him to take on a new power unit in Singapore, which exceeds the season limit of four units per driver. Consequently, this will result in a penalty demoting him to the rear of the grid for the race.

• Key Details:
  • Russell expected to receive an upgraded power unit at the United States Grand Prix later this month.
  • Mercedes aims to fast-track this upgrade for Singapore to minimize future penalties.

Both Mercedes drivers have faced power unit issues this season, with Antonelli previously starting from the back at the Italian Grand Prix and managing to win after an impressive recovery.

The Marina Bay Street Circuit poses a tougher challenge for overtaking compared to Monza, making Russell's situation more precarious. Mercedes deputy team principal Bradley Lord stated that investigations into the Bahrain incident revealed a mechanical failure, but the root cause remains undetermined.

Despite introducing a significant aerodynamic upgrade in Bahrain, Mercedes struggled against Red Bull's Max Verstappen, with team principal Toto Wolff labeling it their "worst weekend of the season." Lord noted that a combination of factors, including updates and track conditions, contributed to their performance issues, which they are currently working to address as they prepare for the upcoming race weekend in Singapore.
