The concept of the super-fast Avant is more tightly woven into the Audi DNA than virtually any other hallmark of Vorsprung durch Technik, and that concept has been refined yet again in the creation of the new, fourth generation Audi RS6 Avant. Bristling with the technological accomplishments already delivered by the new A6 Avant, the latest addition to the Audi Sport fold combines formidable twin-turbo eight-cylinder TFSI power with state-of-the-art efficiency features including mild hybrid drive and cylinder-on-demand technology, helping to deliver epic performance as responsibly as possible.
