The first post-war Audi emerged in 1965 as a cross between the DKW F 102 and a 4-stroke engine developed for military purposes by Mercedes and brought into series production by Auto Union. The Auto Union Audi was presented to the public at the 1965 International Motor Show, initially under the simple model designation "Audi". The image here shows a prototype and was taken in the 'Stilhalle' in Ingolstadt. It still has the taillights of the DKW F 102 and its trim elements. Both were subsequently modified to give the models greater visual distinction.
