The allroad shares its platform with the second generation “C5″ A6 Avant (station wagon), although an advanced air suspension, larger wheels with all-terrain tires and flared and unpainted bumpers give it a distinct appearance and more overall flexibility over varying terrain; Audi’s quattro system is standard equipment.
Audi’s 2.7Â L, twin-turbo V6 was available initially, alongside the 2.5Â L TDI Diesel engines with 132Â kW (180Â PS) and 370Â NÂ·m (273Â ftÂ·lbf) torque. A variant of the corporate 4.2Â V8, shared with the A6 sedan, was made available in 2003, first in North America and later in other markets, and a less potent TDI followed in 2004.
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 21Â cm (8.3Â 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 a 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 16Â cm (5.5Â in) above road level and simultaneously stiffen the spring and damper rates to provide a sporty driving experience much like that of the Audi S6. Many owners choose to fit their allroad with a sportier, road oriented tire to emphasize it’s sporty side, as most owners will never venture onto terrain rough enough to necessitate having a tire specifically designed for off-road conditions.
