Sebastian Vettel was dramatically disqualified from the Hungarian Grand Prix for not having enough fuel in his car at the finish – elevating Lewis Hamilton to second. But stewards investigated Vettel more than four hours after the chequered flag due to an insufficient fuel sample size taken by FIA technical delegate Jo Bauer. Teams are required to provide a one litre sample of fuel to the FIA as per rule 6.6.2 in the Formula One Technical Regulations for the end of a grand prix. And we just have to show the FIA that it was in there, and 300 millilitres is enough for their fuel sample. Vettel has previous with this fuel issue having been caught out in 2012 along with Hamilton in qualifying sessions which saw them thrown out. Demand to see the FIA’s explanation for the Vettel and Russell ruling saw the website crash.
