Robert Kubica and Nick Heidfeld
had relatively high expectations heading into qualifying for the Italian Grand Prix with both running comfortable in the top ten throughout much of the race weekend. However a double engine failure ended the day prematurely for both drivers in the second
round of qualifying leaving the duo 13th and 15th on the grid.
"Both drivers were stopped by engine failures in the second part of qualifying," admitted BMW Motorsport Director Mario Theissen. "As far as we can see from the data they both had the same problem.
"The two engines were new, therefore the reason cannot be too much mileage or too high stress. A thorough analysis will only be possible once we have dismantled the engines. Of course, this has a negative effect on our race prospects.
We expected good grid positions on this track."
With just eight engines permitted per driver, BMW Sauber now fact the prospects of grid penalties later in the season should they require a ninth engine.
"Obviously the failures also influence our engine planning for the remaining races of the season," Theissen concluded.
