Neither Force India driver was able to finish the Hungarian Grand Prix as both cars were affected by hydraulics issues.
Adrian Sutil, in his 100th race, retired early on, while Paul di Resta pulled into the garage during the closing stages.
"It'’s disappointing not to finish, especially as the race was coming back to me after a poor start on the medium tyres," said Sutil.
"Just before my pit stop I had a problem with the gear shifts and I could not shift up any more. I came into the pits and it became clear we had a hydraulic problem so the team immediately told me to park the car."
Di Resta added that he is confident Force India can 'bounce back' at the Belgian Grand Prix.
"I made a good start and was very aggressive on the opening lap," he said.
"I think I was up to about P12, but from there on it was difficult because I was struggling with the balance and tyre performance. Without the speed we did not have the flexibility to make the strategy work and points were looking out of reach. Towards the end of the race the team called me to the pits because it seems we had picked up a hydraulic issue, similar to the problem with the other car."
"Over the summer break we will regroup, analyse things properly and take a fresh approach into the second part of the year."
