With five of 15 events now in the history books Bourdais, who was half a second behind Wilson at the flag, now has a still considerable 30 point lead in the championship but more importantly looked mortal for the first time this year.
Fourth place represented a seasonal best for Junqueira, although the fact that he was nearly 40 seconds behind Allmendinger at the end tells its own story. Da Matta finished fifth, three seconds behind his Brazilian countryman for his best finish of the year while top rookie Clarke cheekily past a disgruntled Tracy on the final tour to take a career best sixth place.
Disgusted with the handling of his Forsythe Racing Lola all day, Tracy finished just ahead of Clarke's CTE Racing-HVM teammate Nelson Philippe, who was the last unlapped runner in eighth place while Andrew Ranger and Oriol Servia completed the top ten.
Incredibly all 18 starters were running at the finish although Team Australia rookie Will Power was more than a dozen laps down after some minor mechanical issues.
British rookie Katherine Legge toiled towards the rear of the field in her PKV Racing Lola, occasionally looking like breaking into the top ten but never managing it and eventually finishing 13th.
Allmendinger's maiden series win moves him up to third in the standings, 30 points behind Wilson and 60 behind Bourdais while another solid run from Ranger keeps him in the top four. Behind the Mi-Jack Conquest Racing driver there is a four-way tie for fifth place between Tracy, Mario Dominguez, Philippe and da Matta.
