Montreal:With gremlins creeping into the machine resulting in a double retirement at the Canadian Grand Prix, Force India team management admitted they need to address certain issues before hitting the Magny-Cours track in France for the eighth event of the year in just two weeks' time.
The Canadian Grand Prix turned out to be a huge disappointment for the outfit with Adrian Sutil retiring on lap 13 with a gearbox issue, while Giancarlo Fisichella's race was halted on lap 51 with a spin and anti-stall problem.
Chief technical officer Mike Gascoyne admitted that he had expected to get both the cars to the flag.
"From our starting positions of 16th and 17th we had a good race pace. It was a shame that Adrian stopped with a gearbox problem so early on as he was very competitive with the group in front. We've yet to identify the reasons exactly.
"Giancarlo's pace in the first stint was also very good and we made a call to leave him out during the first safety car period, mainly to get track position. On his pit stop we decided to leave the fronts on and only change the rears, but as he pulled away he had an engine stall, which was very strange as we haven't seen it before, and it compromised his race," said the engineer.
"We will just have to move onto Magny-Cours now and hope for better there," he added.
Sutil was particularly upset after generating good race pace.
