An important addition to the Audi lineup, the new 2006 A6 Avant wagon features seating for five and almost 34 cubic feet of luggage capacity, making it a logical consideration when shopping for an upscale family car. The 2006 Audi A6 Avant comes with a 3.2-liter, 255-horsepower V6 linked to a six-speed automatic transmission that delivers power to all four wheels through Audi’s Quattro AWD system.
