Michael Schumacher may be hoping for a "better performance" for the rest of the weekend, however, he admits it's looking too good for Merc GP.
Schumacher could only manage tenth place, 1.686s off the pace set by Red Bull's Sebastian Vettel, while his team-mate Nico Rosberg fared even worse, finishing P13.
And, unfortunately for Schumacher and Rosberg, he concedes Mercedes GP are looking as if they will struggle this weekend at the Hungaroring.
"Today we saw two sessions where neither the long runs nor the single laps were looking particularly good," said the seven-time World Champion.
"We are not up to the speed that we normally are on Fridays and unfortunately our car does not look very good here at the moment.
"We have to look deeply into the data now to see if there are any specific reasons or if it is due to the character of the circuit.
"I think our specification is better than we had at Silverstone but we have to make it suit this track. We obviously hope for a better performance tomorrow and Sunday."
Team boss Ross Brawn admits there is a lot of work to be done overnight if they hope for an improved showing in Saturday's qualifying.
"We had a busy day working with our revised aero package to find the right direction for qualifying and particularly the race.
"Both drivers completed some good set-up work but Nico and particularly Michael are not completely happy with our position at the end of today.
"We have a fairly clear picture of where we expect the prime and option tyres to be positioned for qualifying and the race but we have a lot of work ahead this evening to improve the cars for tomorrow."
