After a stronger qualifying at Silverstone and a second place finish in the race, BMW Sauber driver Nick Heidfeld is confident the qualifying form problems that have plagued him recently are a thing of the past.

"Already in Magny-Cours I made some good progress although I was not quite making it into Q3, I was just a few-hundredths off Robert (Kubica) who obviously gets on with this year's car very well," Heidfeld said. "It has been a process over a couple of months looking at the problem and finding the problems I had, working out with the engineers and doing some changes on the set-up, mainly on the mechanical side actually. Doing some changes on tyre preparation and changing my driving style a bit. All that has helped me to improve my qualifying performance over one lap. My race performance already worked quite well. The last races have shown that it is probably going in the right direction, having two second places in the last three races. I hope it continues like that."

"In the beginning I did hope there would be one big thing I would change and suddenly 'Boom' it would work," he added. "Unfortunately that was not the case. It was hard with a lot of small things coming together but I think I have not discovered all of them, so I think there is even more potential to make more progress."
