The Audi 4000 was sold in the U.S. from 1980 through 1987 before it was replaced with the 80/90 series. It could be purchased through the years with either a 5-cylinder engine or a four-cylinder that grew from an initial 1.6-liter, then to a 1.7-liter and finally to a 1.8 liter. The 4000 was of compact size with a length of 176.6 inches and a wheelbase of 99.4 inches, about the same size as the current Audi A3.
