This year's Le Mans 24 Hours is now Audi's race to lose, according to team boss Wolfgang Ullrich.
The German manufacturer has been unable to challenge Peugeot on pace all week long, but its R15s now lie first and second with seven and a half hours remaining after the retirement of the #2 908 from the lead with an engine failure.
Timo Bernhard in the #9 Audi is running 2m15s ahead of team-mate Benoit Treluyer in the #8 car. The only remaining works Peugeot is the #1 car, which lost four laps with an alternator problem on Saturday night, is more than a lap behind.
"It is now in our hands, it's only us that can lose now," said Ullrich.
He added that he has ordered his drivers to keep their concentration, with the #1 Peugeot close enough to be a factor in the remainder of the race.
"It will not change anything, we will continue as planned," Ullrich said. "The most important thing is to run consistently and not take unnecessary risks in traffic. I have told [the drivers] to keep concentrating - that's the way to go."
