So, no blown diffusers anymore, starting at Silverstone. Is this the end of Vettel's dominance? As is widely publicised, Red Bull are gaining between 0.5 and a full second over the other teams with the same technology. This seems like a strange decision. The main reason, says Charlie Whiting, is that because the engine is moving to create downforce, it breaks regulations regarding moveable aero-parts. If this is the case, what about Red Bull's wing last year? They decided that was just fine, but that was a time when if Red Bull slowed down, they would not have had a chance at winning the championship. But this year, they're pulling away and all of a sudden, 7 races in, they need to be slowed down, for entertainment reasons of course. Entertainment=revenue So I have concluded, and feel free to tell me if you disagree, that this decision was made purely to slow Red Bull down. They were aware of the issue well before the season started and yet only now has a decision been made, when it's obvious Red Bull are flying and with no real Drivers Chamionship battle, less people will watch. So this decision has been made completely for spectator reasons. I'm happy with it and hopefully Vettel will now have to show that he IS the best driver and doesnt just have the fastest car, which he is yet to do.
