Wanted to share some 4am pictures from Arnage, at the bottom end of the le Sarthe circuit, where we were sat among hundreds of other (mostly British) spectators during the very early hours of this morning. In the rain. Everyone there was looking for the same thing – glowing, burning brake discs as the cars decelerate hard into the sharp right-hander at Indianapolis. The speed difference between the high-downforce LMP1 cars through this complex, compared with rapid-in-the-real-world race tuned Ferrari and Lamborghini GT1 cars gives you an idea just how fast these strangely silent Audi and Peugeot diesel racers are going. Our photographer Stuart managed to get some good shots to show you what I mean (below)...

Just now we had another reminder of the vast performance difference between the classes, when the LMP1 class-leading No 2 Audi with Tom Kristensen at the wheel collided with a slower LMP2 backmarker in the Dunlop Curves. He’s still in the lead though, with the second place No 7 Peugeot more than a lap behind. My money would be on Audi for the win, but nothing’s certain with the changeable weather conditions here - those Peugeot’s are much quicker when it’s dry (as it is right now). And Audi’s Alan Mcnish is worrying saying: “Peugeot's speed in the dry is insurmountable. I'd like us to get enough of an advantage so that it can dry out and we'll still be OK.”
