Red Bull Racing has admitted it is approaching the British Grand Prix cautious about its chances of success, despite a dominant 1-2 finish last year.
Although the team's RB6 is expected to excel on the high-speed swoops of the Silverstone circuit, major upgrades from a host of its rivals have made it harder to predict what will happen. With chief title opposition McLaren declaring the event to be a key race for both teams in setting the competitive picture for the remainder of the season, Red Bull Racing team principal Christian Horner is taking nothing for granted.
"We don't underestimate Ferrari and McLaren, and even Mercedes, I am sure, will fight back," said Horner. "I am sure there is a long way to go in this championship. We are not even halfway yet."
Horner reckons the fact that Red Bull Racing triumphed on the streets of Valencia, on a weekend when McLaren was expected to dominate, means that previous form appears to mean little.
"Let's wait and see how we go," he said. "Theoretically, Valencia was McLaren territory and we performed very well. Silverstone is a track both drivers enjoy and, hopefully, the next couple of events should come back a bit more our way.
"But we are looking forward to it. It is a track that should, hopefully, suit our car. We had a great race there last year, it will be difficult to top that but we take a lot of satisfaction out of this race win, at a track that arguably we should not be strong at."
