Audi R15 testing, Ascari Resort test track 2009An interesting detail that never saw the light of day (but was observed in the video of the R15 testing at the Ascari test track) concerned what appeared to be dive planes ahead of the rear wheels.
Audi R15 rear dive planesWe're told that the rear diveplanes were good for, "a bit of rear downforce, not much."  Though the ACO took issue and Audi was forced to reconsider using them.
