Ferrari supposedly have a big upgrade for Silverstone, but I seriously doubt it will be enough to get near Red Bull, especially at Silverstone which is pretty much perfect for the Red Bull.
McLaren have been fine recently, the high temperatures mixed with the large number of traction zones destroyed their race in Valencia. The Ferrari's have great traction and are probably the best on the brakes, so Montreal, Valencia, Monaco suited them pretty well. McLaren have a problem with rear downforce (which could be highlighted even further with the banning of off throttle exhaust gases at Silverstone), but in general they have a quick car too. They did win in Canada, and were right on the pace in Monaco/Barcelona. Lewis' poor driving has cost them more than anything else.
Previously, we were used to seeing two teams battling it out, and the performance of each car would vary track to track, as it still does now. However, the new kid on the block have designed a car that is almost perfect. The Ferrari's and McLaren's are good cars, just look how far they are ahead of everybody else, but the performance of the Red Bull is simply staggering and a car like that will be quick regardless of the circuit.
