George Russell set for Singapore grid penalty after Sepang retirement

George Russell is expected to receive a grid penalty this weekend at the Singapore Grand Prix following his retirement at Sepang last week. The Mercedes driver was third behind the safety car, with five laps remaining, when a sudden power-unit failure forced him to stop at the Turn 1 entry. He now needs a new engine for Marina Bay, with the penalty expected to come at this round.

The change comes after Russell has already used four power units during the 2026 season. Any further unit brings a 10-place grid penalty. That could send him towards the back, a particularly significant setback at Singapore’s street circuit, where overtaking is notoriously difficult.

The stakes extend beyond this weekend’s result. Russell arrives in Singapore 84 points behind his team-mate Kimi Antonelli, the championship leader. In September, Antonelli also received a similar penalty at Monza. He went on to win his home Italian Grand Prix from 19th on the grid, passing Russell on his way to victory.

The engine trouble comes amid an otherwise dominant season for Mercedes, but one in which reliability issues have surfaced on several occasions. Before Sepang, Antonelli suffered an engine failure late in the Barcelona race. Russell had already retired from the lead in Montreal after a power-unit problem. At Sepang, the warning came as an unusual noise: Lord recalled Russell saying over the radio, “The power unit is starting to sound funny.”

Mercedes had hoped to take the penalty in Austin, the race after Singapore, although the grid drop had been expected for some time. Russell and the team had also hoped to align the change with the fitting of the ADUO engine. That option is no longer on the cards, meaning Russell may miss out on that opportunity altogether. At Marina Bay, he will therefore face the prospect of a costly starting position on a circuit where making up ground is difficult.
