Barrichello says updates need work

But the Brazilian was still pleased with his performance after securing eighth position ahead of tomorrow's British Grand Prix, where he is now aiming for a top-six finish.

"Top eight in qualifying is a good effort by the team," said Barrichello after qualifying. "We still have to improve but today's result is satisfying and probably the best we could hope for. I hope we can get into the top six tomorrow.

"The cars are all very close, and there aren't too many overtaking opportunities around the lap, so it's going to be a good battle.

"The upgrades are all working well, but they need more development if we are to move higher up the field."

Team-mate Nico Hulkenberg was disappointed with his day after finishing down in 13th position, the German blaming Force India's Tonio Liuzzi for slowing him down.

"Traffic really destroyed qualifying for me today," he said. "As I was going into the first corner on a quick lap in Q2, Liuzzi exited the pitlane under blue flags but didn't move out of my way.

"That ruined my lap from the outset as I couldn't get past him. I also struggled with the car today. I don't know why and I'll be looking into that with my engineers now."
