Paul di Resta sure Force India can deliver 'big' results in season run-in

Although the Silverstone-based outfit is currently eighth in the standings, it thinks it can do better in the second half of the campaign to lift itself ahead of its closest rivals.

"There's still a long way to go in the championship and we need to get back to scoring regular points," said di Resta about the prospects for the remainder of the year.

"Last year we ended the season strongly and we need to do the same this year. Williams are not too far ahead of us, but Sauber have a big points advantage and it's going to be a big task to overcome that.

"But we won't give up; we'll keep pushing and see what we can do. We definitely have the potential to get some big results before the end of the year."

Force India had come in to the season hoping to improve on its sixth place finish in last year's constructors' championship, but it now concedes that Lotus' progress means that feat is out of reach.

Team principal Vijay Mallya reckons there is still plenty to play for though.

"We were sixth in the constructors' championship last year and we had the objective this year of coming fifth," he explained.

"However, the improvement of Lotus has been exceptionally dramatic, so I think to target fifth is probably overreaching our capabilities for this year.

"We should at least target sixth, where we finished last year, and that means getting ahead of both Sauber and Williams."
