Webber frustrated by lack of speed

"We've struggled for speed for most of the weekend," said Webber, who equaled his worst qualifying performance of the season with 14th position.

"It's a new venue here, which brings variety to the positions, but we don't seem to have the pace we had a few races ago, which is quite frustrating.

"There were a few laps I was pleased with, but we didn't make it through to Q3," the Australian continued.

David Coulthard had an ever worse day after failing to make it past Q1, the veteran racer having to be content with 17th place.

"I expected to be able to make it through that first part of qualifying," the Scot said. "On my last run, I ran wide in Turn 5 and dropped about four tenths, although I pulled two tenths back, the net loss over the whole lap meant it wasn't enough to go through.

"It's just the way these qualifying sessions go. That was probably one my messiest sessions and I'm disappointed."
