MERCEDES CONFIRMS GEORGE RUSSELL'S GRID PENALTY FOR F1 SINGAPORE GP

George Russell will start from the back in Singapore after taking a power unit penalty, the consequence of his Malaysia retirement where the engine gave out while running third under safety car. Mercedes confirmed the grid drop Tuesday — Russell's fifth PU of the season, one over the limit.

The timing couldn't be worse. Russell sits 84 points behind teammate Kimi Antonelli with seven rounds left, and the penalty likely costs him access to Mercedes' upgraded engine spec under F1's development rules. He won Singapore last year, but fighting through from the back on a street circuit where passing is nearly impossible turns Sunday into damage limitation.

Mercedes is floundering. Verstappen walked away with Malaysia while the Silver Arrows scrambled to diagnose a performance deficit they still don't understand. The team will split specs this weekend — latest updates on one car, previous-spec on the other — searching for answers. Russell's championship hopes hinge on Mercedes finding them fast.
