History and hot air will be among the prevailing themes at Silverstone this weekend. Red Bull arrives at the track aiming to complete a British Grand Prix hat-trick, with Sebastian Vettel having won in 2009 and Mark Webber taking the honours last year.
Ordinarily the Red Bulls would be ranked as near-unbackable favourites, but there's a twist. Silverstone will mark the introduction of the ban (or rather, the severe limiting) of off-throttle blowing of the diffuser, and with Red Bull having been considered the primary beneficiary of the technology, it's little surprise that its rivals will be eager to see how much of a difference it will make to the performance of the RB7.
Red Bull technical chief Adrian Newey believes that the ruling will come as a serious blow to the team on the basis that the exhaust concept was integral to the overall design of the car. Changing it now, he believes, will make a fundamental difference to how the rest of the car works, and not for the better.
