After the legendary run of turbocharged inline-5 motors ended for U.S. customers in 1995, Audi would not deliver another S6 to these shores until 2002. When it arrived, it came in only one form – the popular Avant package. While many rejoiced that this was at the very least an option, it was still pretty expensive and not everyone loves the fast five doors (crazy though it may seem!). But Audi came very close to offering S performance in the special package which was the A6 4.2 quattro. There were many variants of the C5, and ostensibly the 6-speed manual 2.7T was the “sport” option for the chassis. But the top of the heap 4.2 40V offered you the ART/AWN V8’s torque and 300 horsepower with instant throttle response starting in 2000. Underneath the 4.2 carried a special aluminum subframe. Additionally, the all-aluminum engine was joined by specially flared fenders and hood in aluminum, “door blades” that would later be seen on S models, plus optional 17″ x 8″ Speedline (later changed to forged and polished “Fat Fives”) wheels and upgraded brakes and pads. Suspension was lowered and stiffened with the 1BE sport springs and struts in the optional Sport Package; a 20mm drop was accompanied by 30% stiffer springs, 40% stiffer shocks and larger sway bars. The combination gave a menacing appearance to the C5 that wasn’t really present in the narrow-body 2.7T. Today, the argument over which is the better chassis still rages in multiple fora, and while tuners usually love the twin turbo manual option, many others prefer the velvet hammer 4.2 which really was a defacto S6 sedan Audi never brought here:
