The Audi S6 is the sport-refined version of the A6 sedan. It is packed with technological advancements and has many small design upgrades.

The S6 incorporates a 435 hp V10 engine, Quattro all-wheel-drive, and a level of technical sophistication that few cars achieve. It has daytime running LED driving lights, 19' aluminum wheels, dual-zone climate control, navigation system, and Multi Media Interface high-end radio. Unfortunately, it doesn't come in a manual transmission and owners are penalized with a $1,300 gas guzzler tax in the US.

The S6 is new to the Audi lineup for 2007.
