With a quick glance one notices that Audi design is more about subtle and less about ostentatious. Whereas some cars demand attention with garish spoilers and ground-scraping body kits, the 2007 Audi S6 adds just a bit of zest to the elegant A6 sedan. Enhancements include S6 badges, a thin rear spoiler, 19-inch alloy wheels, a revised front fascia, and wheel wells that have been flared about 14 millimeters. Aluminum door sills bear the S6 insignia, body side moldings are a bit bigger than those affixed to the A6, and the tail end is accentuated by quad tailpipes and a diffuser.
