Williams is set to kick-start its final push to challenge Force India for sixth in the F1 standings when it introduces its final upgrade for the FW32 in Singapore.

The team will take its final upgrade package of the season to the street circuit for the annual race under lights before switching focus fully to its 2011 car but technical director Sam Michael said he expected to see the team take a step forward as it looks to close the eleven point gap to Force India in the standings.

"We have a large upgrade for the FW32 for Singapore," he said. "It will be the last upgrade package we will bring to the car this season and we expect it to be competitive."

Michael added that the double points finish in the Italian Grand Prix last weekend, where Nico Hulkenberg took seventh and Rubens Barrichello tenth, was futher indication that the team is moving in the right direction after a difficult start to the season, which saw it score just eight points in the first eight races of the race.

"It was a good result, one which shows that we are making solid progress with the whole car package," he said. "The FW32 was competitive among the top runners, as demonstrated by Nico's fastest lap time, which was just 0.4seconds off the quickest.

"Nico finished sixth in Budapest, but he was consistently strong throughout the whole weekend in Monza. I would say then that, yes, his overall performance was his best to date.

"Rubens' car was handling similarly to Nico's. Although he didn't have the same pace as Nico over the weekend, he still scored an important point for the team."
