Davidson unsure of Audi potentialPeugeot driver Anthony Davidson expects a close competition between his team and Audi at Le Mans, and reckons that tire wear could make the crucial difference. The new Audi prototype demonstrated great one-lap pace during its racing debut at Spa but could not sustain that speed over an entire stint.

"I think we're looking after our tires better but I'm not sure how or why," Davidson told AUTOSPORT. "We saw at Spa that Audi was quick in qualifying and on ultimate pace on fresh tires, but we had perhaps the stronger package in race trim, so we could continue to drive at 100 percent throughout the whole race – which I'm not sure they were able to do.

"But I still feel they have a lot of potential in their car that's yet to be unleashed, although I'm not sure whether they're ready to do that here, either. Hopefully it's going to be close, like it was at Spa, and the fans will get a good show."
