Former world champion Jacques Villeneuve says it is "strange" he is unlikely to get an F1 drive next year.
Villeneuve thinks he is on his way out of F1
The 35-year-old 1997 champion, who drives for BMW Sauber, is enjoying his best season in years after a disappointing time with BAR.
"Being quicker than my team-mate now, having won the world championship and raced for pole positions, seems to be a negative to get a contract," he said.
BMW look set to pair Nick Heidfeld with test driver Robert Kubica next season.
Heidfeld, 29, is under contract with the German manufacturer until the end of 2007.
Kubica, a 21-year-old Pole, has starred in free practice sessions this year, although he blotted his copybook with a heavy crash during Monaco practice on Thursday.
Villeneuve currently lies 13th in the drivers' world championship with six points.
When asked if he wanted to stay in Formula One next year he said: "Yes, but who with? Right now (I have) no idea.
"It's going well here (at BMW), but no one has yet told me that this means they would like to keep me for next year. It would be a shame if it did not carry on."
Villeneuve ruled out a return to North America - where he won the Indycar title and Indy 500 in 1995 - and said he will not race full-time when he is finishes in F1 .
He also hinted that one-off endurance races, like the Le Mans 24 hours in France, appealed to him.
"After F1, if you want to do something different, it has to be something other than open wheel racing," he said.
"It's (F1) above the rest by a big margin. I live in Europe now. I can't imagine moving back to America.
"As for Le Mans, why not? But that's only one race a year. It wouldn't be a career. If I did it, it would be for fun."
