Audi has added two wagons to the A6 lineup in the U.S., the performance RS 6 Avant and now, the off-road-minded A6 Allroad. The all-wheel-drive A6 Allroad is powered by a 3.0-liter, six-cylinder engine with 335 hp and 369 pound-feet of torque and a seven-speed transmission. The midsize wagon gets off-road features such as an air suspension, roof rails, body cladding and 20-inch wheels. Here's a roundup of select A6 Allroad reviews from the automotive media.
