A pitstop error ruined any hopes that Paul di Resta had of capitalising on his excellent qualifying performance at the British Grand Prix.
Di Resta was badly delayed in the pitstop because of a communication breakdown which meant that the team's pit crew was waiting for team-mate Adrian Sutil rather than the Scot. The Scot said the mistake cost him about 27 seconds and he ended the race in 15th, nine places adrift of his qualifying position.
"It's extremely disappointing to end my first British GP in 15th," a dejected di Resta said after the GP.
"I had a good first part of the race, we seemed quite competitive and I was able to hold on to Jenson [Button]. I think we made the switch to dry tyres at the right moment and we were running well.
"Then I got a call to come into the pits again, but when I got there the team were expecting Adrian. That pretty much ended my chances. There's no way to come back when you lose 27 seconds, it's a pitstop and a half."
In spite of the result, the Force India driver was positive with progress at the Silverstone-based team and was looking ahead to the Nurburgring and the German Grand Prix in two weeks time.
"I think we can continue the way we've been going. We have seen progress with the car and for Germany we've got some updates coming so we're very positive that they'll work. And we're learning from these mistakes.
"The season's not over yet, so I'll just keep plugging away and keep my focus on doing the best job possible for the remainder of the races."
Team boss Vijay Mallya admitted the team had made a "serious error" that resulted in the mix-up: "We called Paul in for his scheduled second stop but at the same time Adrian came on the radio reporting a puncture. We tried to get Paul to stay out so we could service Adrian's car but it was too late and Paul was already in the pit lane.
"We need to regroup and come back stronger in Germany so that we can convert the pace of the car into points."
