Paul di Resta has admitted he isn't sure he will still be with the Force India team in 2012.
Team boss Vijay Mallya said recently he has "clear options" to retain the impressive Scottish rookie - who maintains strong links with Mercedes-Benz - beyond this season.
But di Resta told Press Association Sport at the Nurburgring: "There are many things you hear, but you don't know. I really don't know where I am next year.
"Of course, I'd like to stay here if this is an opportunity. I came in here with a long term view."
But there have also been suggestions that Mercedes would like to run reigning DTM champion di Resta at its works team, despite indications Michael Schumacher and Nico Rosberg are both staying on board for 2012.
"Naturally, I'd love to be with a bigger team battling up at the front, that's my ambition, but Force India is an up-and-coming team," he said.

"This year has been more difficult than we thought. We've not picked up from where we left off last year.
"But sometimes things go down before they go up, and you take one step back to go two steps forward.
"So I certainly hope we can build a future in F1. That's always been the intention," added di Resta.
