As we reported yesterday, Peugeot was clearly the fastest in qualifying for this weekend's running of the 24 Hours of Le Mans. The record-setting runs of all three 908 HDi diesel-powered LMP1 cars places Peugeot's entire field of entries 1-2-3 on the starting grid. That's impressive considering two of Peugeot's car crashed during the past two weeks of practice. Audi is hoping that its team's experience, quicker pit stops and more fuel efficient R10 LMP1 cars will eventually carry it past the Peugeots, despite starting fourth, fifth and seventh on the 55-car grid. And thanks to the speed of Lola Aston Martin driver Stefan Mücke whose petrol-powered car earned the sixth spot on the starting grid, not all the front runners will be diesel-powered.

As for classes other than LMP1, the next fastest LMP2 class was dominated by the Porsche Spyders not surprisingly, while LMGT1 is being led by the #63 Corvette Racing C6.R. The Corvettes will be chased this year by the particularly fast #50 Larbre Competition Saleen S7 and some slower but determined Aston Martin DBR9s from Aston Martin Racing. Finally, LMGT2 will be another great battle between Porsches and Ferraris, with the #76 Imsa Performance Matmut Porsche 911 GT3 RSR on pole for the class. Remember the amazing GT2 class finish of last year's race between Flying Lizard's Jorg Bergmeister in a Porsche 911 GT3 RSR and Risi Competizione's Jaime Melo in a Ferrari 430GT? If not, watch it again here as a reminder of why Le Mans is absolutely amazing.

As we mentioned yesterday, Audi and Peugeot have been locked in a battle of lap times all week at Sebring Raceway in preparation for the 12 Hours of Sebring endurance race on Saturday. In yesterday's practice sessions, Audi turned in a very fast lap of 1:43.195s that would eventually earn it the pole position. Peugeot answered Audi's effort later in the day, however, during the actual qualifying session for the race that would determine the starting grid. The 908 HDi driven by Stephane Sarrazin crushed Audi's top lap in practice with a time of 1:43:117s, which effectively secured Peugeot the pole position.

Unfortunately for Peugeot, fate stepped in and bitch slapped the French automaker's racing team. Welcome to America, guys. Just nine minutes after the qualifying session began and after the 908 HDi had recorded its fast lap, the No. 8 Mazda was involved in an accident bad enough to cancel the session entirely. ALMS rules state that a minimum of ten minutes must be run in a qualifying session for it to count. Therefore, Peugeot's fastest lap time was thrown out. Since the nine-minute long qualifying session couldn't be counted, organizers used lap times from earlier in the day during practice sessions in which Audi set the fastest lap time mentioned above.

An epic battle is shaping up for this weekend's running of the 12 Hours of Sebring. Audi versus Peugeot. The R10 TDI versus the 908 HDi. Diesel versus diesel. This will be the first and perhaps only time that these two teams race on American soil, though the contest will be repeated many times in the European Le Mans Series this season. Since Monday, Audi and Peugeot have been battling for the best lap times during practice sessions in preparation for this weekend's endurance race at Sebring Raceway, and Peugeot got the upper hand on both Monday and Tuesday. Audi, which is fielding two cars to Peugeot's one, finally fought back today posting the fastest lap time of the week thanks to driver Dindo Capello, who ran a 1:45.491, just 0.017 seconds faster than Stephane Sarrazin in the Peugeot 908.

But Audi and Peugeot in the LMP1 class should be wary of focusing too much on each other, as there are other entrants that could spoil their fun. Marco Andretti, for instance has been blisteringly fast in his Andretti Green Racing Acura ARX-01b, setting the second fastest lap time overall on Tuesday. As we learned from watching the LMP2 class beat up on Audi last year, Le Mans racing is anyone's game. The nature of endurance racing, however, favors fuel economy, and therefore the diesel-powered R10 TDI and 908 HDi should have the advantage. There will be plenty of great racing in the GT1 and GT2 classes as well, with Aston Martin squaring off against the Corvette Racing Team and Porsche taking on Ferrari, respectively.
