Between Rosberg and Massa at the flag, Adrian Sutil
secured a handful of points for Force India, while Petrov - who parked up as soon as he crossed the line - was followed home by Pastor Maldonado, the mercurial not only claiming another top ten result for Williams, but opening his own F1 account 24 hours after the controversial clash with Hamilton that earned him a five-place grid penalty.
Paul di Resta was a couple of seconds away from giving the 18th-placed starter another points finish - a remarkable streak that has existed for several races - while Kobayashi survived both his moment with Hamilton and the subsequent stewards' enquiry to take twelfth. Senna's disappointing Renault
debut ended in 13th, ahead of Jarno Trulli
and Heikki Kovalainen, who battled back from their turn one collision to again top the third division teams, finishing ahead of Rubens Barrichello's Williams, the Virgins of local favourite Jerome d'Ambrosio and Timo Glock, and the remaining HRT of Tonio Liuzzi, who rounded out the finishers.
At the front, meanwhile, Vettel crossed the line just under four seconds ahead of his team-mate, giving Red Bull
its first victory at Spa and a rare 1-2 finish, only the second this season after Turkey.
The 25 points accrued by the German lifted him to 259 overall, now 92 clear of Webber with 175 on offer over the remaining seven rounds. Alonso and Button both took advantage of Hamilton's mistake, to climb into third and fourth respectively, although only eleven points continue to cover the trio. RBR, meanwhile, strengthened its grip on the constructors' standings as the F1 circus prepares for Monza in two weeks' time.
The Italian circuit is not thought to favour Red Bull, but then the same was said of Spa.....
