The Audi RS 2 Avant was a limited edition, high-performance Audi Avant (Audi marketing for a station wagon / estate car), manufactured from March 1994 to July 1995. Collaboratively designed as a joint venture between Audi AG and Porsche and built on Audi's 80 Avant, designated internally as P1 (instead of B4/8C that it was based on). It featured the most powerful version of Audi's inline-five cylinder turbocharged engine. It represents Audi's first "RS" model, and the first of their high-performance Avants.
