About Audi A6
Audi’s C5 series A6 Avant formed the basis for a semi-offroad model in 1999, labeled “Audi allroad Quattro”. Compared to the regular A6, the allroad featured an advanced air suspension system, allowing for increased ground clearance; larger wheels with all-terrain tyres, and flared and unpainted bumpers, giving it a distinct appearance and more overall flexibility over varying terrain. As the name “allroad Quattro” suggests, Audi’s Torsen-based quattro permanent four-wheel-drive system was standard equipment for all versions.
The standard adjustable air suspension system can lift the car high enough to provide 208 mm (8 in) of ground clearance; a low-range mode (an option with manual transmission), absent from other Quattro-equipped vehicles, can be selected with the touch of a button. When used together, 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. (Source Wiki)
