For those who are interested in more than the 2007 Audi S6’s stellar powertrain, the finely-appointed interior has you covered. That’s where you’ll find power-adjustable sport seats wrapped in Silk Nappa leather, a dual-zone automatic climate control system, a leather-wrapped sport steering wheel, and birch gray wood trim (carbon fiber is optional). Tunes are courtesy of a 13-speaker Bose surround system with a six-disc CD changer, which can be controlled through the S6’s MMI system with its seven-inch monitor.
