Nico Hulkenberg 'unsure' about Formula 1 future with Force India

The 24-year-old German stepped up from his role as the team's test and reserve driver in 2011 to take a race seat alongside Paul di Resta for this season.

Hulkenberg lies 15th in the drivers' championship, two places behind his team-mate, but has scored points in three of the last five grands prix and has outqualified the Briton five times in the opening 10 races.

However, this recent form is not enough to convince Hulkenberg that he will be kept on by team boss Vijay Mallya, even if he did admit that he would like to remain at the Silverstone-based team for 2013.

When asked by AUTOSPORT if he thought he had done enough to keep his seat, the German answered: "I'm not sure. You'd have to ask Vijay.

"But I'm happy with the job I've done, I'm happy here and I can see myself staying here."

Despite Force India's fluctuating form this year, Hulkenberg sees no reason why the VJM05 cannot be just as competitive at this weekend's Hungarian Grand Prix as it was in Germany, despite the Hungaroring and Hockenheim circuits providing different challenges to the cars.

"It's hard to tell [how well suited to the track the car will be," he added. "I don't actually think it makes much difference. We'll be there or thereabouts either inside the top 10 or maybe just outside it. That's the pace of the car."
