George Russell faces disqualification from the Belgian Grand Prix after his Mercedes was found to be 1.5kg underweight in post-race technical scrutineering in parc ferme. Russell seized an amazing victory in the race after pulling off a 34-lap run on a single set of hard tyres to finish just ahead of his team mate Lewis Hamilton in a hard fought race on Sunday. But that result is in jeopardy after post-race checks found that the W15 failed to meet minimum weight requirements. The official stewards document stated that: "After the Race, car number 63 was weighed and its weight was 798.0 kg, which is the minimum weight required by TR Article 4.1. "After this, fuel was drained out of the car and 2.8 litres of fuel were removed. The car was not fully drained according to the draining procedure submitted by the team in their legality documents as TR Article 6.5.2 is fulfilled. "The car was weighed again on the FIA inside and outside scales and the weight was 796.5 kg. The calibration of the outside and inside scales was confirmed and witnessed by the competitor.

The document was signed by Jo Bauer, the FIA's long-standing technical delegate working with the teams on pit lane throughout the weekend. Historically, such reports are invariably confirmed and upheld by the race stewards. The usual consequence of a car being underweight it that the car is excluded from the results. That would strip Russell of his win, and hand victory to Hamilton in his place with McLaren's Oscar Piastri promoted to second and Ferrari's Charles Leclerc joining them on the podium. There is no indication that Hamilton's car might also be underweight, or that Russell was aware of the issue or gained an advantage from it during the race.
