The A6's front seats are supportive enough, but rather flat and firm compared to the grippy seats in the sporty S6. Rear-seat riders won't have as much room in the A6 or S6 as they will in the class leaders, and the rear bench is sculpted for two butts; hump riders won't ride long in comfort.
Trunk space in sedans is ample at 15.9 cubic feet, and the rear seats fold down for better storage space. The A6 Avant wagon can transport 20 cubic feet of cargo with the seats in place and 58.6 cubic feet with the rear seats folded. A power-operated tailgate is standard on wagons, along with roof rails.
