Mercedes GP boss Ross Brawn is confident that Red Bull Racing can still be caught this season despite having the quickest car of the field.
"I think so," Brawn told Autosprint magazine when asked if Red Bull was still within reach. "In their design there are aspects different from anyone else's, so I think others will introduce them over the next races. For instance, I know that everyone is looking with interest at Red Bull's exhaust system. What they haven't managed to get to work is the F-duct. It's what makes McLaren competitive: on a suited track it makes up for the deficiencies they have in relations to the RB6.
"As for the championship table, Red Bull is still completely reachable," added Brawn, whose team is 71 points behind Red Bull, now second in the standings, one point behind McLaren.
Brawn, however, believes Red Bull has improved significantly since last year, and he reckons its car is likely to be strong in all kinds of tracks.
"At the beginning of last year we had a better car aerodynamically," he said. "Then they closed the gap and even bettered us aerodynamics wise, but we remained better from a mechanical point of view.
"We know from our analysis that we had an advantage on tracks like Monaco, Valencia, and even Monza, which is very quick but with few corners. Under braking and in traction we were better. Now they've improved; they've understood their weak points and this year, while maintaining a fine aerodynamics package, they are stronger mechanically. Nowadays there are no more circuits that don't suit them."
