Mercedes driver George Russell to start Singapore Grand Prix from back of grid after engine failure

George Russell will start the Singapore Grand Prix from the back of the grid after Mercedes confirmed he needs a new power unit. The decision follows an engine failure in Malaysia that forced him to retire from third place. Russell is now 84 points behind teammate Kimi Antonelli in the championship. The penalty applies only to the Grand Prix, not the sprint race. Mercedes is also evaluating an engine upgrade that may be brought forward to Singapore.
