The Wartburg 311 was a car produced by East German car manufacturer VEB Automobilwerk Eisenach from 1956 to 1965. The 311 model was manufactured in a number of variations, including pickup, sedan, limousine, coupé, and as a two-seat roadster. The two-stroke engine was enlarged to 992 cc in 1962. An interim model, called the Wartburg 312 and featuring the chassis developed for the succeeding 353, was built from 1965 until 1967.
Production of the Wartburg 311 was already underway at Eisenach by the end of 1955. The car was a development of the existing EMW 309. This was the car previously identified as the IFA F9, which, in turn, had been based on the 1940 DKW F9 scheduled for launch in 1940 until the Second World War intervened.
The basic architecture of the pre-war design, forcibly acquired from Zwickau-based Auto Union, was retained, albeit with the chassis lengthened by 10 cm, which combined with long overhangs to create a larger car
