The 4000 was introduced initially in the U.S. as a 1980 model to replace the aging Audi Fox. The initial offering was a 1.6L 4-cylinder with 4-speed manual transmission, both in two and four door versions. A two-door, 5-cylinder model was later offered, with a 5-speed (Designated as the 4000 5+5).
In 1981 the displacement of the 4-cylinder was increased to 1.7L, and a 5-speed maunal transmission was made standard. The 5-speed models often carry the 4+E badge that signifies 4 normal speeds plus an economy gear. This was a wide ratio 5-speed box. A 5-cylinder model with automatic transmission was also added. The Audi Coupe was also introduced in 1981 with a 5-cylinder engine.
