Jun.1 (GMM) Adrian Sutil, whose contract expires this season, will not rule out departing Force India at the end of 2009.

The 26-year-old German has contested more than 40 races with the Silverstone based team, previously known as Spyker, since making his Grand Prix debut in 2007.

2010 would therefore be his fourth consecutive season presumably at the back of the grid, but Sutil told Germany's Auto Motor und Sport that his plan is to graduate to a leading team.

"That is every driver's goal," he said, "and also mine. Really I just want to win; with which team is for me not a topic.

"Force India has made progress," Sutil acknowledged, "and we will have to see how it looks for the coming years."

He admitted that, in his three years in F1, there have been occasional talks between his management and other teams.

"At the moment this is where I am," Sutil said. "The contract runs out at the end of the year and then we will see."

He suggested that the team's smaller budget than many of its rivals is not the biggest issue. "I don't think it's just the money; it is the whole package," said Sutil.

"Perhaps we are just missing a 'superbrain' -- like what Red Bull has in Adrian Newey."

Sutil's 2009 car may get a boost next month, when Mercedes' KERS system is scheduled to be fitted for the first time.

But the German, possibly to be further disadvantaged due to his height, isn't sure. "I think KERS is a good thing, if it works. But for the moment it's not really working for anybody."
