Hamilton pole, 2013
I predict merc as usual the fastest car by some margin, followed by williams and ferrari, who are also expecting some 20 bhp boost from it's PU after the summer break. If past events are anything to go by red bull (along with all renault powered cars) should struggle at this venue a lot, similar as in Austria, and could see themselves eclipsed by toro rosso if they fail to perform to their fullest potential.
One other interesting thing I'll be watching is speed trap data coming out of radillon. This should give us some clear indication of which car is carrying most speed trough eau rouge, given it probably won't be anywhere near flat this year. S1 trap will also be interesting for top speed.
Blanchimont to remain flat, but not for all cars maybe?
