The deal about Porsche and Audi not competing in the same class was from back in 2000 when Porsche had plans for the LMP2000 to run against the R8s. I have heard now that Audi would actually want Porsche to compete against them for some competition! As of right now, there are no agreements between Audi and Porsche about not competing in the same class! Hopefully that agreement will be taken advantage of and we will see Porsche LMP1 vs Audi R10 vs Peugeot LMP1 at Le Mans in a year or two!!!
