The Audi R15 TDI: Friday Practice
Here’s Lucas Luhr again, this time during Friday during practice, Turn 1 at Road Atlanta. The Audi R15 TDI had been freshly polished to a mirror sheen and looked absolutely gorgeous. The sharp-eyed will notice that the car is sporting single dive planes underneath the headlights. In the race, this car ran two for additional grip on the wet track. FYI, I’ve added a lightbox plugin so you can enlarge the picture and feast your eyes on this stunning car.
But wait, there’s more… Here’s a sound clip of several of the cars going by. The Audi is first. Notice how much quieter and smoother sounding it is than the others that follow.
