Larbre Competition's Vincent Vosse and Greg Franchi rounded out the top five - the team's best result to date, while Philipp Peter and Allan Simonsen were sixth in their Gigawave Motorsport-run Aston Martin DB9. Peter and Simonsen were the only Aston Martin DB9's in the points as neither Jetalliance car reached the chequered flag.
Further down the order JMB Racing's Ben Aucott and Alain Ferte were seventh followed by AF Corse's Toni Vilander and Gianmaria Bruni, who took the honours in the GT2 class, ahead of team-mates Thomas Biagi and Christian Montanari in the sister Ferrari 430.
The Ferrari cars had an extremely close fight with the #61 Prospeed Competition Porsche of Emmanuel Collard and Richard Westbrook, but a problem with a headlight in the dark saw the Porsche, which had led the race, drop to fifth.
"It was a very difficult race," Bruni reflected. "I was very careful in the first braking turns. Emmanuel Collard, in the Porsche, passed me in a corner, in a very nice manoeuvre and then for the next fifteen laps was in front of me. It was very difficult for me to pass him on the straight. But I managed to pass him in the end. I braked late and managed to pass sideways, luckily enough not to touch, and went up the inside."
Matteo Malucelli and Paolo Ruberti took third for BMS Scuderia Italia - and tenth spot overall.
The result mirrors exactly the current GT2 Drivers classification, where Vilander and Bruni have taken a nine-point lead in the GT2 drivers' classification, with their team-mates Biagi and Montanari second, and Ruberti/Malucelli third. AF Corse have taken a 19-point lead in the Teams classification.
The FIA GT Championship now heads to Oschersleben in Germany next month for the fourth round in the series.
