The FIA has announced that Sebastien Buemi has been scrapped from the official qualifying results. The fuel sample in the Swiss driver's Scuderia Toro Rosso didn't match the regulations. Buemi qualified 16th, just in front of his teammate. The official statement by the FIA states: "The stewards, having received a report from the FIA Technical Delegate that the fuel sample taken after Qualifying from Car 18 showed an increase in one given GC (gas chromatography) Peak Area of an absolute amount greater than 0.1 per cent for the component present at a concentration below 0.8 per cent, and having heard from the FIA Formula One Analytical Chemist and the Team Representatives and examined the fuel test graphs, determine this to be a breach of Article 19.8.3 of the 2011 FIA Formula One Technical Regulations and decide to impose a penalty of exclusion of Car 18 from the results of Qualifying."

Buemi will now start from the back of the grid.

Update: Scuderia Toro Rosso have released a statement in which they explain the cause of the problem. They think the fuel was contaminated by a chemical that was inside the fuel system they fitted after FP2. The statement by Scuderia Toro Rosso said: "During Friday’s FP1, Buemi’s car had a fuel pressure problem, which then got worse at the start of FP2 which is why he did not do a timed lap in that session. After FP2 the entire fuel system on his car was changed. When the fuel sample was taken from his car after qualifying, it did not match the one provided to the FIA prior to the start of the season. The team believes that some part of the new fuel system contained a chemical that contaminated the fuel and caused the non-conformity."
