I think that Audi can't win...ofc 4s gap isn't such a big gap like we have seen in 2008 and in so many times of Le Mans History but this year, Peugeot isn't the same as 2008 and Audi have changed too.
Indeed Peugeot learn a lot about 2008 and feel more like an endurance team whereas in 2008 it was something like an F1-prototyp team which wanted to make a sprint. In other side, Audi was the great endurance team, with an endurant prototyp which couldn't fail without a human error (check 2007) so they were sure to finish the race. What happened? Peugeot failed because of that !
This year, this is the 908 which can't break (Peugeot engine can do 35 000kms without any problem as pescarolo said (this is what Peugeot engineer told him when he was worrying about the engine after last year quali) !). So the car is secure whereas Audi have a car which is slower atm and I think which is going to stay at least 2s slower than the Peugeot and a car which have shown some technical failure today like an overheat problem for #8. So in fact I don't see how Peugeot can fail this race...but Le Mans is Le Mans so everything can happen
EDIT : 245.678 km/h average for Bourdais's pole ! So the record can be beaten again this year (222.304km/h for '71 #22 Martini Porsche 917 K)...(I hope tomorrow not to rain and see some 3.18
)
Not sure if I really believe that figure. I wonder at what kind of performance level? One Le Mans race is about 5000 km.
