Audi top first qualifying session at Mosport

Frank Biela set the fastest lap of the 20-minute session to pip team-mate Rinaldo Capello to provisional pole position. Biela's best time was little more than one tenth of a second ahead of the Italian, whose attempts to improve were thwarted by traffic.

Third and fourth fastest were the two Panoz Roadsters qualified by Jan Magnussen and Johnny O'Connell, while championship leader Jorg Muller ended up fifth in his BMW.

Olivier Beretta was fastest in GTS with a 1m17.811s best at the wheel of his ORECA Chrysler Viper. That was just over three tenths ahead of the factory Chevrolet Corvette driven by Ron Fellows.

Alex Job Racing driver Randy Pobst was a surprise fastest in GT. His Porsche 911 GT3-R pipped Brian Cunningham in the best of three Prototype Technology Group BMWs to the top of the timesheets by just over half a second. Missing from the session were the leaders in the GT points, Dirk Muller and Lucas Luhr. The former crashed his Dick Barbour Racing Porsche during the morning practice session and the car couldn't be repaired in time.
