For all the controversy that engulfed Red Bull Racing over the re-allocation of its last upgraded front wing to Sebastian Vettel's car, the British Grand Prix was a great weekend for the team.
Heading to Silverstone, the talk was of how McLaren's exhaust-blown diffuser upgrade would allow it to leapfrog the energy drink-fuelled team. It wasn't to be. Come Friday night, the diffuser upgrade had been revealed to provide little more than hot air, for now at least, and Red Bull was already well on its way to a fifth win of the season.
But that's not the end of the story. Exhaust-blown diffusers are tricky to get the best out of, especially when grafted onto a car mid-season, and McLaren will run its system again in Friday practice at Hockenheim. A decision will then be made whether to run it for the rest of the weekend, based on data compared to the performance of the old-specification car, which will also run. Chances are, the smoother track surface at Hockenheim will make life much easier for McLaren, and we will see whether it really has closed the gap.
As for Red Bull, there will be the usual raft of upgrades, some of which will inevitably arrive post haste in a Transit van a few moments before qualifying! But that doesn't necessarily mean that it'll be another Scuderia Milton Keynes walkover.
