The allroad (note the lower case "a") is Audi's sophisticated A6 Avant wagon given the pseudo-SUV treatment. Like the Subaru Legacy/Outback models, the allroad offers increased ride height, all-wheel drive (quattro), and body cladding. The Audi does have adjustable ride height (5.6"-8.2" ground clearance) and a 2.7L 250-bhp twin-turbo V6 to separate it from lesser wagons. The allroad exceeds the 7.1" ground clearance of the BMW X5 and matches the Land Rover Discovery.
Since the allroad quattro was intended to be more than an 'either/or' vehicle, it needed more than an either/or suspension. And since such capability didn't exist among the allroad quattro's direct competitors, Audi's engineers set out to build it.
