Vijay Mallya believes Force India can tackle the final five races of this season with optimism as they seek to retain fifth place in the championship.
Having introduced a B-spec car at the British Grand Prix, Force India have worked their way up to fifth in the standings.
Scoring points in five of the last six races, including two double top-tens, the team has amassed 77 points, 17 more than Lotus.
"I'm feeling optimistic as we approach the final couple of months of the season," team principal Mallya said.
"In Singapore and Japan we continued to show competitive pace and, despite missing the chance to score with both cars, we remain in a solid fifth place in the championship."
Looking ahead to the next race, the Russian Grand Prix, Mallya revealed that Force India will once again bring updates for the car as they look to build on their recent form.
"Russia will give us another chance to unleash more potential from the B-spec car.
"Even at this late stage of the season we continue to bring new parts to the car thanks to all the hard work back at the factory.
"There's every reason to believe we can be competitive in Sochi and we expect to be up there fighting for good points."
