The A6 Avant is the largest station wagon in Audi's vast lineup. It features the same luxury features and technology as its sedan counterpart, and is visually quite similar to the sedan as well. While the sedan can be ordered with V8 power, the Avant comes with a V6 only. There is, however, no shortage of power, as it can produce in the neighborhood of 255 horsepower. The Avant received a significant update for 2009, with a mildly revised front end and a heavily restyled rear.

The rear now has new tail lights, complete with LED clusters that provide better visibility. The wagon has also increased cargo room, and the luggage area features two securing rails that are receded into the floor. An optional automatic tailgate that opens and closes at the push of a button is also available, making this an all-around family vehicle.
