Karun Chandhok was left frustrated after being unable to complete a proper lap in qualifying in Canada. The Hispania driver was forced to miss final practice due to a hydraulic problem and then failed to set a competitive time in the grid-deciding session following an issue with a sensor.
The Indian finished nearly 10 seconds off the pace of his teammate Bruno Senna.
"It was very frustrating today as we missed the third practice and also qualifying," he said. "We have to look into the problems and understand what went wrong. After two good sessions yesterday, it's even more frustrating as this weekend we really could have competed against the other new teams in qualifying.
"It will be a tricky race tomorrow with the tire wear and high probability of safety cars. So, let's see what we can do tomorrow."
Senna, on the other hand, was pleased after managing to qualify ahead of the Virgin of Lucas di Grassi in 22nd position.
"It was a good lap and I am happy with the result as we are in front of another team's driver," he said. "We could work on the set-up which helped us a lot to improve the performance of the car today. Unfortunately, there was rain last night and the track got green again in the morning.
"The track got more grip and quicker even during the first twenty minutes of qualifying. That's why it was important to be out on the track at the end of the session in order to set the fastest lap. Thankfully, I could do a clear one on that period. Now, we have to decide the tire strategy for the race. It is going to be very tricky tomorrow for everyone because of the tire wear, and hopefully we can have a good race tomorrow."
