Jenson Button has admitted BAR will struggle to claim their first Grand Prix victory this season.
The Briton described the team's chances as "very slim," adding: "We have to make a big step forward to do that and we're not going to do that right now."
Button insisted he had yet to make a decision on his future - his deal at BAR runs until 2006 but he has a performance-based get-out clause.
"In a couple of months I'll hopefully know a lot more," he said.
The 25-year-old is understood to have a loophole in his BAR contract which allows him to leave should he have less than 75% of the championship leader's points by the end of August.
Fernando Alonso's victory at Magny-Cours last weekend ensured that was now a mathematical impossibility.
Williams are understood to have first option on Button but the Briton remained tight-lipped.
"It's not something I want to go into now," he said.
"I'm not thinking about at the moment because it is British Grand Prix this weekend, and there's still a lot for the team to achieve."
One of the things on Button's to-do list with BAR is improving their standings in the constructors' standings, where they languish in last place.
BAR finished second behind Ferrari last season but the resurgence of Renault and McLaren means they Brackley-based team have struggled to keep up.
"At best we will finish sixth, maybe fifth in the constructors' championship," Button said.
"We thought we achieved a lot last year and moved the car forward quite a bit over the winter, but we didn't realise the steps McLaren had made.
"It's an issue, but nothing the team can't get over. We've already made a big improvement from the start of the year."
And Button wants to get BAR's charge back on track at Silverstone, where he finished fourth last season.
"A podium would be awesome," he said. "It is achievable.
"I think McLaren are going to be really strong, but behind them it's going to be a close race. Hopefully we can put on a good show for everyone."
