Mark Webber says he will be pushing hard for points in his remaining races with Jaguar before joining Williams. The Australian, who switches teams after this season, came sixth in the German GP - his best drive of the year.
He said: "The last three races have been very rewarding, with reliability greatly improved and the pace of the R5 embarrassing some of our rivals.
"We'll be pushing as hard as ever and chasing every single point we can until the last race in Brazil in October."
The former Minardi driver, who has been in F1 for three seasons, also admitted that it would be difficult to leave the Milton Keynes-based team.
"I've never enjoyed leaving the teams in the past, as it's important to forge strong relationships with the people you work with, and in doing so you become a part of that family.
"I'm still very close to all the people at Minardi, and I will remain the same with those at Jaguar Racing who have put me in a tremendous position to progress my career."
