That is the claim of the energy drink owned team's racing consultant Dr Helmut Marko, who acknowledged that Australia and Malaysia was not a good start to the campaign for a third-consecutive championship-winning season.
Comparing the reigning world champions with McLaren, Ferrari's technical director Pat Fry agreed on Tuesday: "I've been slightly surprised by Red Bull's lack of pace."
Marko acknowledged: "Over the race distance (in Malaysia) we saw that (Sauber's Sergio) Perez was the fastest," the Austrian said on Servus TV.
"In wet but also in dry conditions, the Sauber was absolutely the fastest one.
"On the other hand, the whole package did not come together for us," Marko insisted, referring specifically to bad pitstops, and broken radios.
"There are so many things that have to come together. But we have a plan for how to deal with it for China, to solve our problems.
"I'm confident that we will get it back together sooner or later.
"It makes things of course more exciting, although not quite as easy for us," he smiled.
