BMW Sauber kept up its 2007 record by qualifying both of its cars in the top ten for the US Grand Prix, but it is a measure of the team's ambition that Nick Heidfeld was frustrated at having qualified behind the two Ferraris.

The German reckoned that third was on the cards, which would have mirrored his Canadian GP grid position, but a small mistake on his last lap meant that he missed the second row by eight-thousandths of a second, with Kimi Raikkonen going on to partner Felipe Massa behind the two McLarens.

"The balance of the car was better today, but I am not really happy with my qualifying as, on the last lap, I didn't get it right in the last corner," Heidfeld admitted, "I had some graining with the tyres and, obviously, was too aggressive and slid a bit away from racing line. Otherwise, I think I could have qualified in front of the Ferraris."

Heidfeld admitted, however, that he remained optimistic of a better showing in the race itself, possibly leading to another podium finish.

"In Montr?al, our car was very good over the race distance, so I hope we can continue like this," he reasoned.
