Like Volvo's XC line of cars, the Audi Allroad is a tall wagon with AWD and off-road capability. To date, however, the Allroad has only been available in a version based around the A6. These latest spy photos show a new A4-based Allroad in testing, confirming our news last year that such a model was in the works. Cues that tip this car as a definite Allroad vehicle include the wider fenders and taller ride height, plus the new bumpers with a more ruggedized look, new air intake housings, addition of foglights and other off-road specific design cues. As yet it's not clear if the A4 Allroad will be available as both a sedan and a wagon, but reports suggest the car will be kept simple - meaning air suspension appears to be an unlikely option.
