The #2 Audi Sport Team driven by Benoit Treluyer leads at the halfway mark of the Le Mans 24 Hour hold in a 55 second lead over its nearest rival.
The Audi leads the Peugeot 908's of #9 Pagenaud, #7 Wurz & #8 of Sarrazin at the 12 hour mark.
Hour twelve began with the Hope Racing #5 ORECA car struggling with problems that have persisted since the start of the race. The leading #2 car pitted, like clockwork, 11 laps after its last pit stop, only stopping to refuel.
The #9 Peugeot in the hands of Bourdais set a blistering time of 3.28.739 before he handed over to Pagenaud, while team-mate Wurz pitted for fuel only.
Then drama as the fifth placed #10 Peugeot 908 of Team ORECA Matmut in the hands of Duval went of at Playstation suffering substantial damage to the front right of the car. Initially, it looked like the car had retired however Duval drove back to pit road and after a 12 minute pit stop rejoined at the back of the LMP1 class, 8 laps down.
In GTE Pro the #56 BMW had an off before pitting, as Hand relinquished control to Priaulx. The GTE Am sole remaining Aston Martin of Gulf AMR Middle East (#60) had an off at the Porsche Curves.
A flurry of pit stops followed as the #48 ORECA Nissan (2nd in class) and #26 Nissan changed drivers.
The GTE Am class was very close as the #81 Flying Lizard Porsche 911 overtook the #70 Labre Porsche 911 before they both pitted and the #70 overtook its rival in the subsequent laps.
There will be no LMP2 defence by the #42 Strakka Racing car as the car stopped out on track in the hands of Danny Watts at Mulsanne corner.
The #2 Audi pitted once again 11 laps after its last stop to take on fuel and he was joined by the #41 Greaves Motorsport (1st in LMP2) and the #13 Rebellion Racing Lola (5th in LMP1).
The hour ended as it started with the #5 Hope Racing car back in its garage, but the sole remaining Audi remained in the lead.
Retirements: Oak Racing #15 retired with a power steering failure while the #57 Krhon Racing Ferrari F430 retired. The #39 Pecom Racing also retired.
