The Audi A6 is a comparably priced alternative to BMW's 5-series and the Mercedes-Benz E-Class, offering both performance and superb interior appointments in both full-size sedan and wagon bodystyles. The sedan offers comfortable seating for five, while the Avant wagon features the same high-quality interior as well as 33.9 cubic feet of cargo space. Safety is paramount across the line, and the optional and legendary Quattro all-wheel drive system gives excellent control even in harsh weather conditions.
