Christian Horner is hoping his drivers can give the Mercs a "hard time" on Sunday after losing out in qualifying for the British GP.
Lewis Hamilton and Nico Rosberg locked out the front row of the grid with the British driver the only one to drop into the 1:29s on Saturday afternoon.
Merc's flying pace meant the Red Bulls had to settle for third and fourth with Sebastian Vettel ahead of Mark Webber.
Their team boss, though, is hoping to get back on top come Sunday's grand prix at the Silverstone circuit.
"It was a pretty solid qualifying," Horner told PlanetF1's Michelle Foster.
"Obviously the Mercedes is very quick over a lap and congratulations to Lewis but hopefully we can give him a hard time tomorrow."
Asked whether Merc's impressive pace had anything to do with that test, the Red Bull boss responded with a smile: "Surely not."
