Russell retirement could force earlier Mercedes engine change

Mercedes is reviewing the timing of George Russell’s next power-unit change after his late retirement at Sepang. An earlier change could bring a 10-place grid penalty forward and put a planned upgrade at risk; Bradley Lord said the team still needed to assess the effect on Russell’s power-unit pool.

George Russell’s late retirement at Sepang in Sunday’s Bahrain Grand Prix in Malaysia has left Mercedes reassessing the timing of his next power-unit change. An earlier switch could bring a 10-place grid penalty forward and put a planned upgrade at risk.

Russell was running third under the Safety Car before pulling over at Turn 1, Motorsport.com reported. The FIA’s final classification lists him 20th, a DNF after 49 laps. After the race, Mercedes team principal Toto Wolff told Sky Sports F1 that the problem was a power-unit failure, was not caused by the Safety Car and had not yet been assessed by Mercedes.

Deputy team principal Bradley Lord said Mercedes still needed to understand what the failure meant for Russell’s power-unit pool and might have to alter its previous plan. Motorsport.com reported that Russell had already used the four power units allotted for 2026, so a further unit would incur a 10-place grid drop. The report said he was believed to be set to take the penalty in Austin but might need to do so earlier, possibly at Singapore.

Russell’s next unit was planned as an updated version under the Additional Development and Upgrades Opportunities (ADUO) system. Motorsport.com said an earlier change could mean he misses the upgrade; Lord described the combined effect as a possibility.
