The C5 platform S6 Avant offered a considerable amount more power and performance than the A6 on which it was based. Packing a 4.2 liter, 40v all-aluminum V8 that developed a meaty 335 hp and a hefty 310 ft-lb of torque, the S6 was capable of sprinting to 60 in around 6 seconds. Those numbers might not seem as impressive as they once did, but back in the late 90s/early 00s that was no mean feat for a healthily sized family hauler that tipped the scales at just over 2 tons. To keep the tires firmly planted on the road, the S6 utilized a Torsen-based Quattro system that split power evenly between the front and rear wheels. Unlike the Allroad, these steel-suspended Avants ran the 1BE sport suspension, while aluminum body bits helped (marginally) to keep weight in check. Exterior styling cues separating the car from its more humble siblings were kept rather subtle, limited to slightly wider fender flares, chunky S6 specific Avus alloys, door blades, a slightly redesigned bumper and aluminum caps on the wing mirrors. This was a car that might go unnoticed in the school parking lot, but could hit (a limited) 155 MPH on the highway on the way home.
