George Russell’s victory at the Belgian Grand Prix is subject to a stewards’ investigation after his car was found to be underweight after the chequered flag.

The winning car was weighed after the race and found to be at the minimum weight, 798kg, but after fuel was drained from the Mercedes, it was found to be 1.5kg underweight.

The matter has now been referred to the stewards for investigation and a possible penalty.

If the car is confirmed to be underweight without explanation, such as damage, Russell will be disqualified from the results.

“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,” a statement from the FIA technical delegate said.

“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 796.5kg. The calibration of the outside and inside scales was confirmed and witnessed by the competitor.

“As this is 1.5kg below the minimum weight requested in TR Article 4.1, which also has to be respected at all times during the competition, I am referring this matter to the Stewards for their consideration.”

Russell’s teammate Lewis Hamilton finished second and is not under investigation, meaning he would take the win if Russell is disqualified.
