Schiff warns Mercedes power-unit problems could cost Antonelli more wins

Naomi Schiff warned that recurring Mercedes power-unit problems could cost Kimi Antonelli more victories and the team points in the constructors' championship. Speaking on the Sky Sports F1 Show after the Bahrain Grand Prix in Malaysia, she said issues had cropped up more than once, including on George Russell's car, Antonelli's and other Mercedes-powered cars.

Russell retired with a power-unit failure in the closing laps at Sepang. The retirement extended Antonelli's lead over his team-mate in the drivers' standings to 84 points: 320 to Russell's 236.

In Mercedes' post-race debrief, deputy team principal Bradley Lord said an initial inspection of Russell's car indicated a mechanical failure on the power-unit side; the root cause had yet to be determined.
