Dyson Lola wins Mosport

Lehto and Werner were trying to score their fifth consecutive victory in the ALMS this season, while Weaver and Leitzinger won for the first time since July of 2003 at Sonoma.

The Audi team gambled by not changing tyres on its final pit stop, putting Lehto ahead of Leitzinger by nearly 30s with 45 minutes remaining in the event. But 10 minutes later, with Leitzinger slicing seconds off the lead every lap, Lehto slid off the track at Turn Five with a flat tyre, handing the lead back to Leitzinger for the final time.

"I was very concerned when they did the fuel-only stop," said Leitzinger. "I was hearing the split times and I was catching up with JJ, but it was far from sure. Then I saw him in the barrier and breathed a sigh of relief. This win was awfully satisfying."

"It was absolutely perfect," said Weaver. "I couldn't make a racing car do better than that. We have a lot of miles at Mosport and it paid off handsomely."

"The tyre just blew up," said Lehto. "Fortunately it was in a place where I could get back to the pits. We had a good race going and it was a lot of fun today, but I wish we hadn't lost that tire at the end."

Oliver Gavin and Olivier Beretta won the GTS class in a Chevrolet Corvette C5-R, while Clint Field and Robin Liddell won the LMP2 class in a Lola B2K/40-Judd. Timo Bernhard and Jorg Bergmeister won the GT class in a Porsche 911 GT3 RSR.
