The Audi 4000 5+5 was launched on to the American market in the 1981 model year. The 5+5 was essentially an 80 B2 two-door saloon with the 2144 cc five-cylinder engine from the 5000 and a five-speed transmission, the precursor to what would become the Audi 90. Fitted with various sporty parts such as an oil pressure gauge, sports interior, and alloy wheels, it was accompanied on the American market by the 4000S. This is a more pedestrian yet well-equipped four-door version with the same engine, originally only coupled to a three-speed automatic.
