Perfect for a one-car garage, the Audi RS6 is an all-rounder by offering a great blend of luxury, performance, and practicality. It's a breath of fresh share in a world of RS, AMG, and M SUVs, provided you can handle the prohibitive asking price. The Four Rings are just about done with the development of combustion engines, but there's still life left in the twin-turbo V8. More power is in tow for the 4.0-liter, and it's coming soon.
