The Audi Al2 was a concept car presented by Audi at the 1997 Frankfurt International Motor Show (IAA). It served as a direct precursor to the production Audi A2, which entered production in 1999.
In the early 1990s, Volkswagen Group set a corporate objective to design and produce a passenger car that met ambitious fuel-efficiency targets through the application of lightweight construction and advanced aerodynamics.
Within this haze, an unusual model quietly surfaced in the early 1990s—the Audi 100 RS4. Despite sharing its badge with the later and far better-known B5-generation RS 4 Avant, this prototype was entirely different.
