Lewis Hamilton admitted he was mystified by the pace of the Red Bull Racing team after a dominant display in qualifying in Hungary.
The McLaren driver finished over over 1.5 seconds off pole-setter Sebastian Vettel, as Red Bull proved untouchable around the Hungaroring circuit.
"For us it's not case of a tenth or two here and there. It's a second in the middle sector and half a second in the last sector," the Briton said.
"We look at the onboard footage and we just laugh. That's just insane how fast they are going.
"Our car is the best is it has ever been. I don't know what the hell they are doing, but it's incredible the pace they have here."
Hamilton said he extracted "every last drop" from his McLaren to qualify in fifth position.
"I'm happy with today's result. I was relieved to get into Q3 - it was very close - and I feel I pulled every last drop out of the car. So I'm satisfied with the job we did today," said Hamilton.
"Obviously, we'll have to work hard again tomorrow - but, all things considered, it's a good place for us to be starting from tomorrow: it's on the clean side of the track, which is a positive, and it's a long haul down to Turn One. So anything's possible. As I say, I'm quite happy."
The McLaren driver admitted the start and the first lap will be very important to achieve a good result.
"We'll stay focused for tomorrow: I need to get as good a start as I've been getting for the past few races, stay clean, get around the first corner and keep moving forwards after that.
"It would be great to make up some places off the grid because it's very hard to overtake around here. But we'll do the best job we can. I'm ready for it. Bring it on!"
