Audi is celebrating the sale of an R8 GT supercar in Lake Forest, Illinois with a billboard dedicated to the owner. The lighter, more powerful variant of the R8 V10 puts out a wicked 560hp and 398 lb-ft of torque from its direct injection 5.2-liter V10 engine. The billboard is right, slow drivers should definitely make way for this German supercar. On a side note: for those of you unfamiliar with Lake Forest, it is located just outside Chicago. Kudos to The Audi Exchange for their clever sign!
