Heidfeld surprised by BMW's pace

Fresh from his podium at the Hungarian Grand Prix three weeks ago, Heidfeld continued with his impressive form to qualify in sixth position.

He will start from fifth, however, following a penalty to Ralf Schumacher.

A delighted Heidfeld said BMW had taken an "enormous" step forward following the Hungarian race.

"I am a little bit surprised that everything went so well," admitted Heidfeld. "Our performance in Hungary was, in my opinion, due to exceptional circumstances. If we compare today's result to the races prior to then the improvement is an enormous step forward.

"It shows the guys in Munich and Hinwil worked really well during the summer break, and here we have some more aerodynamic improvements including a modified front wing. Nevertheless I am realistic and think it is going to be harder for us in the race, but our goals are points."

BMW's strong day was completed by Robert Kubica posting the ninth fastest time as he continues shining following his stunning debut in Hungary.

"It was a good qualifying as we have both cars in the top ten," said Kubica. "We struggled with the set-up this morning and had understeer, but suddenly in qualifying it became oversteer. It went from one side to the other and unfortunately the car was really difficult to drive.

"However, I managed pretty well to push on one lap and I shall see what happens tomorrow. The conditions are changing and we should have more rubber on the track, which should help to make the rear more stable."
