Jenson Button feels McLaren produced a much better qualifying performance than expected on Saturday.
The 2009 World Champion will start Sunday's British Grand Prix in 11th place while his team-mate Sergio Perez is down in P14, but Button believes they got the best out of the car.
"I'm higher on the grid than I expected after practice," he said. "Yesterday, I didn't think we'd qualify ahead of one Ferrari and just behind the two Lotuses. But I was much happier in qualifying than I'd been all weekend - we should be positive that we've improved the car.
"I think 11th was the best we could have realistically achieved today. Even if we'd got into Q3, we'd probably have been 10th; so starting 11th means I'll have a new set of tyres and will start from the clean side of the grid."
Perez didn't have the best of Saturdays as his tyre "exploded" during the final practice session in the morning, but he is positive he can move up the grid come race day.
"It's been a difficult day," the Mexican said after qualifying.
"The puncture in FP3 wasn't the best preparation for qualifying 0 and it made it more difficult, because we had to change the damaged floor for the older-spec version.
"This afternoon, I struggled a little with the warm-up of my tyres during Q2; I lost temperature when I was stopped and weighed at the FIA scales. We've been a bit unlucky all day.
"Still, we were a lot closer today than we were yesterday. Even if it's not apparent, we've definitely made some improvements, and I think we might have had the potential to slip into Q3 if we'd been a little bit luckier.
"Our race pace should be better than our qualifying pace. Tomorrow is still going to be difficult, but I'm positive we can go forwards from here."
