Williams undecided on blown diffuser

Nico Hulkenberg, Williams, European GPWilliams is undecided yet on whether it will race its exhaust-blown diffuser at this weekend's British Grand Prix - with the team keen to wait on how testing of it goes on Friday first.

The Grove-based team will join McLaren in introducing the low exhaust configuration for the first time. Ferrari, Mercedes GP and Renault all introduced their versions of the Red Bull Racing-inspired concept in Valencia a fortnight ago.

It is understood the team has shaken down the new parts in a straight-line test, but it will want proper data from actual running at Silverstone before giving it the green light to remain on the car.

Technical director Sam Michael said: "The FW32 will have further upgrades for the British Grand Prix, including an exhaust blown diffuser, rear brake duct and front suspension changes.

"We'll evaluate the exhaust during the practice sessions on Friday and will make a final decision as to whether we race it that night."

Rubens Barrichello, who delivered Williams' best result of the season so far with fourth place in Valencia, is hoping the upgrades bring a good step of speed.

"Valencia was a good effort by the team," he said. "It was satisfying to see us move forward and I hope that we continue to do so. To help with that, we have more upgrades coming for Silverstone, which I hope will make the car go faster again.

"There's a good vibe in the team to get us back to where we should be and I'm proud to be a part of that effort."
