The Audi RS6's all-round talents as a fast, comfortable, roomy and quiet-cruising high-performance estate are unquestionable. Put simply, if that's what you're looking for, there's little else to touch it. But for some it might feel a little restrained, so if you want your performance car to have even more thrilling sounds, handling and speed, buy a Mercedes-AMG E63 S Estate instead.
