Audi Allroad Suspension
The first generation allroad shares its platform with the second generation "C5" Audi A6 executive car, and its rear end is almost identical to the A6 Avant, the estate version. The main differences are an advanced air suspension system, larger wheels with all-terrain tyres, and flared and unpainted bumpers, giving it a distinct appearance and more overall flexibility over varying terrain.
Audi's trademark Torsen-based quattro permanent four-wheel drive system is standard equipment for all versions.
Off-road capabilities
The allroad was designed with the capability to tackle rough road conditions in mind; its standard adjustable air suspension system can lift the car high enough to provide 208 mm (8 in) of ground clearance and a low-range mode, absent from other quattro-equipped vehicles, can be selected with the touch of a button. When used in conjunction, the two systems made it possible for the allroad to complete an official Land Rover test-course, thus far it is the only car-based SUV that has been proven capable of doing so in testing.
Conversely, the air suspension can lower the vehicle down to only 142 mm (6 in) above road level, and simultaneously stiffen the spring and damper rates to provide a sporty driving experience, much like that of the conventional A6 with the sports suspension.
