High Quality Content by WIKIPEDIA articles! The Audi S6 is a high-performance version of the Audi A6, a mid-size luxury executive car produced by German automaker AUDI AG. It went on sale in 1994, shortly after the "A6" designation was introduced, replacing the "100" nameplate. The original S6 (Ur- S6) was largely the same car as the outgoing, original Audi S4 (C4) (Ur-S4), with the only visible differences being new body-cladding and badging. The S6, like all Audi "S" models, is fitted as standard with Audi's trademark quattro four-wheel drive (4WD) system, the S6 using the Torsen-based permanent 4WD. Audi was restructuring their model lineup in early and mid-1990s, and in late 1994, began selling the fifth generation (C4) Audi 100 model, re-badged as the Audi A6. Wanting to keep a sports-saloon in their lineup, the company made small revisions to what was previously known as the Audi S4, renaming it the Audi S6; the S4 name would eventually be re- used for a completely different model derived from Audi's smaller Volkswagen Group B platform-based Audi A4.
