Kimi Raikkonen will start from 12th on the grid in Canada after missing out on progressing to Q3 in qualifying for the Grand Prix in Montreal on Saturday, and revealed that he had been grappling with handling problems during the session.
"Obviously it's disappointing to go out in Q2 but we had some issues with the differential which meant the car wasn't handling as it should," he explained. "I think it's a hydraulic problem ... We had some problems yesterday and it seems to have come back.
"When the grid is so tight it makes a big difference not having the car exactly as you like it," he pointed out.
Despite the disappointment, the former world champion was still hoping that things would prove better in race trim on Sunday.
"We had no issues on the long runs yesterday, we have options to choose from with the tyres, and the warmer weather is definitely suiting us better so hopefully we can put everything right before tomorrow and go from there," he said. "The race is where it counts, so let's see what we can do."
His team mate Romain Grosjean escaped similar handling problems and was able to put his Lotus into the top ten and make it through to the final part of qualifying, ultimately claiming seventh place on the starting grid - and regretting not achieving even more.
"For sure we wanted a bit more from qualifying but this is a tricky circuit to get right, and the big variation between conditions yesterday and today didn't help," he said, adding that he'd expected the warmer conditions to help the team more than they actually had.
"The car felt pretty strong but my last run could have been better, which is a shame. Still, making it through to Q3 is never a bad thing and it's a long race tomorrow."
Grosjean said he was optimistic about what he could manage in Sunday's race in Canada.
"Our car has been quite easy on tyres so far this season and hopefully that could make the difference," he said. "Last time I started in P7 we ended up on the podium, so let's hope it can happen again tomorrow!"
