Product Overview
Audi S6 C5 (Typ 4B) is an executive sedan in production from 1999 to 2003. It was powered by with a single 4.2-liter naturally-aspirated V8 engine paired to either a 6-speed manual or a 5-speed ZF 5HP24A automatic transmission.
This NA V8 features 5 valve per cylinder design and is shared (to a large extent) with the contemporary D2 S8 and B6 and B7 S4s. It has proven to be the most reliable V8 engine to have ever come out of VAG / Audi.
Unfortunately, the ZF 5HP24A transmission is known to have a weakness in Clutch A drum, which leads to premature failures.
Drivers who appreciate handling will be pleased to know that the C5 S6 comes with multi-link suspensions at all four corners. This provides the best cornering performance and tunability, at the expense of cost and a little bit of durability.
