The car received a positive reaction when first exhibited, initially badged as the DKW 600, at the Frankfurt Motor Show in March 1957.
[3] Outwardly there was little change, but the C pillar became more angular and the engine was enlarged to 889 cc which was reflected by a claimed increase in output to 40 bhp (30 kW).
The DKW F12 roadster which appeared in 1964 extracted 45 bhp (34 kW) from its 889 cc three-cylinder engine, and this more powerful unit became available in the F12 saloon for a few months from February 1965.
Early in the summer of 1965 Volkswagen acquired the Auto Union business from Daimler Benz: production of the two-stroke DKWs was almost immediately terminated.
In the market place the DKWs had been facing an increasing struggle to compete with similarly sized more powerful four-stroke-engined offerings from Volkswagen and, more recently, Opel.
By the end of 1965 the plant formerly controlled by Auto Union was building Audi badged cars, with four-cylinder four-stroke engines designed, before the change of ownership, in collaboration with Mercedes-Benz.
