"Red Bull have taken pole at every race this year and I would expect that trend to continue," he told the Telegraph.
Also looking stronger is Mark Webber, with his team orders stoush with Red Bull and Sebastian Vettel appearing to have given him wings.
At the same time, championship leader Vettel appeared to struggle somewhat in front of his home crowd, but forecast rain and low temperatures could give him the edge over Ferrari in the coming days.
"In the rain we still have a problem," admitted Silverstone winner Fernando Alonso to Auto Motor und Sport. "The worst thing for us is a wet and cold track."
German Vettel told O Estado de S.Paulo: "Our forecast is for rain."
I need six or seven 'teammates' to be able to finish ahead of Vettel and take points off him
With his 80 point lead, however, the weather is a minor concern for the bigger picture. More important for Alonso is a consistently quick car -- and for McLaren to improve.
"I need six or seven 'teammates' to be able to finish ahead of Vettel and take points off him. Otherwise it (the title) is going to be difficult," he said.
"I love it that there is a disagreement. It is what McLaren need," he said.
