Amongst unappreciated Audis, the C5 S6 seems to be pretty high on the snub list for enthusiasts. Complaints that they were overly complicated and underwhelming were understandable in some regards as the C5 S6 only came in Avant and automatic form to the U.S.. Indeed, at the same time as the S6 was offered, you could get a twin-turbocharged Allroad 6-speed for a bit less money than the S6. Since it was effectively the same car with a manual and height-adjustable suspension, one would wonder why Audi would offer the S6 at all. However, compared to some other Audis of the same vintage, the S6 holds some advantages. To lighten the porky C5 up slightly, the S6 featured some aluminum body bits up front. Unlike the previous turbocharged inline-5, power came from a capable V8 – rated at 340 horsepower, it was effectively the same motor shared with the S8 and nearly 100 horsepower more than the V6. The S6 also got a special and unique version of the Ronal-made Avus wheel at 17″x8″, instead of the 17″x7.5″ on the B5 S4. Inside the S6 was much the same as the rest of the C5 lineup, though sport seats were standard as with the S8. However, for second or third-hand owners, the big advantages to the S6 are the steel suspension in place of the air-controlled suspension the Allroad featured – a complicated system that has proven failure prone. Additionally, the belt-driven V8 doesn’t have the same guide issues of the chain-driven later V8s in the S4 V8. True, you are still subjected to the transmission woes of this generation Audis – but properly cared for, even the weak-spot transmissions can go for some time. Today I have two examples of the S6 Avant; which is the one to buy?
