Both Kobayashi and Perez have lost their points-scoring finishes
Both Sauber drivers of Kamui Kobayashi and Sergio Perez have been disqualified from the results of the Australian Grand Prix.
Their Sauber C30’s upper rear wing element was found by the stewards to not be within the regulations. The FIA have disqualified the team on the basis of them breaking Sections 3.10.1 and 3.10.2 of the technical regulations.
The removal of these two drivers from 7th and 8th means that Felipe Massa and Sebastien Buemi take their places, and Adrian Sutil and Paul di Resta move up to 9th and 10th respectively.
Sauber have stated their intention to appeal. Technical director James Key has said:
"This is a very surprising and disappointing result.
It appears that there is a question over the top surface of the uppermost rear wing
element, this area is not the working surface of the component and therefore
relatively unimportant to its function.
Certainly this has not lead to any performance advantage. We are checking the design
of the parts now to better understand the situation and we intend to appeal the
decision made by the stewards."
Sections 3.10.1 and 3.10.2 read as follows:
Article 3.10.1
"Any bodywork more than 150mm behind the rear wheel centre line which is between
150mm and 730mm above the reference plane, and between 75mm and 355mm from the car
centre line, must lie in an area when viewed from the side of the car that is
situated between 150mm and 350mm behind the rear wheel centre line and between
300mm and 400mm above the reference plane. When viewed from the side of the car
no longitudinal cross section may have more than one section in this area.
"Furthermore, no part of this section in contact with the external air stream may
have a local concave radius of curvature smaller than 100mm.
"Once this section is defined, 'gurney' type trim tabs may be fitted to the trailing
edge. When measured in any longitudinal cross section no dimension of any such trim
tab may exceed 20mm."
Article 3.10.2
"Other than the bodywork defined in Article 3.10.9, any bodywork behind a point lying
50mm forward of the rear wheel centre line which is more than 730mm above the
reference plane, and less than 355mm from the car centre line, must lie in an area
when viewed from the side of the car that is situated between the rear wheel
centre line and a point
350mm behind it."
