BBC Sport at Istanbul Park
McLaren believe they can match Red Bull for pace in Sunday's Turkish Grand Prix but will struggle to out-qualify them.
McLaren's Jenson Button narrowly beat Red Bull's Sebastian Vettel in Friday practice at Istanbul Park.
And McLaren team principal Martin Whitmarsh said: "Our race pace is good - some analysis would suggest we are a bit quicker in race pace.
"But they've killed us in qualifying so far and if you can't qualify it makes it a bit more difficult."
The Red Bulls have been in dominant form on Saturdays so far this year, taking pole position for all six races.

But Whitmarsh said McLaren's analysis of the two cars' performance in Friday practice suggested that Button and team-mate Lewis Hamilton, who was fourth fastest in second practice after setting the pace in the morning session, could challenge them in the race.
"We're a little bit closer to Red Bull but they are still clearly the car that we've got to beat. Our long runs look good - and there are signs that we are just about there.
"They are able to turn it on in qualifying. Who knows what fuel load they're running (on shorter runs)? Maybe they're running a lot more than us.
"In the long runs they weren't running more than us - I know that - so we were competitive there.
"But the right thing to assume is that until proven otherwise they're quite a lot quicker in qualifying. If that's not the case on Saturday, I'll be pleasantly surprised."
Hamilton added: "I have no doubts that tomorrow in qualifying Red Bull will pull out something extra they always do. I think Red Bull will be quick tomorrow and the Ferraris but I do feel we'll be able to compete with them."
