Developed jointly with AUDI AG under the internal designation “Project Q1,” the S6 plus transformed the C4-generation S6 4.2 through a comprehensively reworked V8, shorter transmission ratios, revised running gear and a more exclusive specification.
The Audi S6 plus Avant was the first complete automobile offered by quattro GmbH and the model that transformed Audi’s small personalization subsidiary into a vehicle manufacturer in its own right.
Introduced for the 1994 model year, the Audi RS2 Avant represented the first production model to wear the RS designation and marked the beginning of what would become Audi's highest-performance road car lineage.
