I went to the Mazda Champ Car events today and saw that Bourdais was slipping slightly in turn 8 which goes into the long backstretch of turn 9. Other drivers were slipping too, though.
Still good enough for 3rd on the grid for Sunday's race.

I asked him about the upcoming endurance race and I think he was suprised a guy from the U.S. knew he was driving a car way over there.
