Barrichello: car not capable of more

Barrichello finished down in 18th position, two laps down, after being unable to fight with the Spyker of Adrian Sutil.

"Today we just didn't have any pace and despite the fact that I was pushing as much as possible, there was nothing coming from the car," said Barrichello.

"The race started badly when I was pushed wide at the exit of turn two and ended up at the back of the field.

"Overtaking is next to impossible at this track so that was the story of my race really. Everyone at the team is feeling the pain at the moment.

"We know how bad the situation is but we have to keep our heads up and keep working at it over the break to find some improvements."

Jenson Button, who one year ago was celebrating his first victory, also endured a torrid day, going out of the race with a mechanical problem on lap 36.

"What can I say? We all know the problems and how much work there is to be done," he said. "The problem that brought my race to an end appears to be a sensor problem as I couldn't get full throttle for a few laps before I eventually slowed for the blue flags.

"Then the engine just stalled. Before that we were massively off the pace and I struggled with huge understeer. Our results today speak for themselves."
