Rubens Barrichello is certain that Williams will make "a big step" in performance from its 2011 to its 2012 car.

12643 - Barrichello sure Williams will improve

Williams has endured the worst season in its history with Barrichello responsible for four of the five points that the team has scored. With only Lotus, Virgin and HRT below it in the constructors' championship, the team has undergone extensive restructuring throughout the season with the biggest change being Sam Michael leaving as technical director and Mike Coughlan coming in. Along with switching from Cosworth to Renault engines Barrichello said that the refreshed team will make clear progress next season.

"Engine side, structure, new thinking, motivation, everything can be a big step next year," Barrichello is quoted by Autosport. "That is what I believe. I don't know if it is going to be a winning car but it will be a hell of a lot better car."

Barrichello cited a lack of leadership during the changeover period as the main reason for the team's lack of competitiveness this year, but said that it was now fully focused on improving in 2012.

"The problem this year was the leaving people until the others came in and that missing three to four months, that was no leadership at that time. Right now people are accommodating quite well, they have done everything they could to improve this car which is a very bad one, so they are putting all the efforts on a new one."
