The second Audi, piloted by Capello Scot McNish and seven-time winner Kristensen, led for over 16 hours, with McNish setting a new lap record of three minutes, 27.204 seconds on the 8.45-mile circuit along the way.
The Spaniard traded fastest lap times with team-mate Sebastien Buemi in a quiet opening half hour and improved his lap time by over six seconds, but he still finished the session in 20th position, one place behind his team-mate.
