Both Toyota cars have been excluded from the qualifying results at the Australian Grand Prix after their cars were found to break technical rules. The FIA's decision promotes world champion Lewis Hamilton to 18th - he had dropped from 15th to last place because of a gearbox change.
Toyota's Timo Glock of Germany and Italian Jarno Trulli qualified sixth and eighth but will start Sunday's race from the back of the grid. Officials said the cars had rear wings that were too flexible. Williams are also launching a protest against the rear wings on the Red Bull and Ferrari cars.
Flexible rear wings are banned in Formula 1 because they can bring performance advantages. Because of this, the F1 technical regulations have strict stipulations about how much a wing can flex.
This is because a wing can be designed to flex in such a way as to improve the car's straight-line performance without harming its cornering capability. In such instances, the aerodynamic drag on the car reduces as the wing flexes. The wing then snaps back to their original shape as the driver slows for a corner, increasing his grip.
