3.28.301. The No. 33 Barazi-Epsilon Zytek led LMP2, after an earlier misfiring problem had been repaired. Oreca's Saleens were the fastest two GT1 cars, while Ferrari and Porsche were close to one another in GT2. The session was red flagged about halfway through because of an accident in which the No. 53 JLOC Lamborghini Murciélago, driven by Marco Apicella, hit the wall at the first Mulsanne chicane.
