Continuing Audi's commitment for its S-line to deliver the most balanced combination of world-class luxury and exhilarating performance continues with the S6. Based on the A6, this vehicle packs a punch with quality Audi S6 parts and looks good doing it. All the premium options like leather interior, superior sound system, and advanced safety features are combined with high output engines like the Lamborghini-sourced V10 offered from 2006-2011 or the twin-turbo V8 offered in the following generation. Styling takes it cues from the A6, with subtle additions like a body kit, larger wheels, and special headlights. And, of course, handling is improved with Audi's Quattro all wheel drive system offered as standard equipment. Fun fact: the first Audi S6 was actually just a re-badged S4 from the early 1990's.
