Felipe Massa has been excluded from the results of his home Grand Prix for a tyre infringement, and has thus lost his eighth place.
The decision benefits Romain Grosjean, Max Verstappen and Pastor Maldonado move up to eighth, ninth and 10th places respectively. However, Williams has submitted an appeal.
Massa fell foul of the recently introduced procedure which sees tyre temperatures and pressures checked on the grid, which is intended as a safety measure to stop teams running excessively loe pressures.
The Brazilian’s right rear was checked and found to be at 137C, a huge 27C above the prescribed maximum of 110C. The pressure was 20.6psi, which was 0.1psi above the limit set for Interlagos.
However, the team believes that its own measurements prove that the tyre was legal.
In essence the FIA and Pirelli are concerned that teams can use high blanket temperatures on the grid to make the pressures legal – and when the temperatures drop, the pressures fall and provide a performance benefit.
