Sebastien Buemi has lost his 16th place qualifying time for a fuel irregularity, and will thus start at the back of the grid.
The team had the option of appealing but after Shell’s technicians ran their own test on STR’s behalf, the result proved to be the same as the FIA’s. The team has now issued the following statement:
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.
Jaime Alguersuari takes over 16th position and everyone else behind him will obviously move up a place.
Buemi will also now have the option to make major set-up changes and start from the pitlane, as he will have little to lose by so doing.

Yet another bullsh!t FIA deal. They keep killing the sport with slow torture, one miserable and inflexible rule after another.
