Auto Union AG , Ingolstadt, Germany. 1958 - 1962

This combine was constructed in 1932 to develop a grand Prix racing team to rival Mercedes and obtain Nazi government finance which the individual companies could not afford to undertake individually. The distinctive interwoven four circles of their logo represented the 4 companies of the group, Audi, DKW, Horch and Wanderer. The rear engined Auto Union racing cars became a legend in their own time, but unfortunately very few survived the Russian overrun of East Germany after the war. A complete set of fully operational replicas have been built from the original drawings by Crossthwaite & Gardiner and bodied by Keith Roach for Audi in the late 1990's

The post war Auto Union was a DKW economy car with a 3 cylinder 2-stroke engine of 981cc and a more stylish convertible body by Baur and called the 1000SP. About 6,640 were made.

The DKW saloons were also called Auto Unions from 1957 to 1963.

The somewhat unusual DKW 3 cylinder 2-stroke engine lent itself to tuning for competition and this coincided with the new Formula Junior which started in1958. The result was that several enterprising tuners were able to extract over 80bhp from this high revving engine. A leading exponent was Gerhardt Mitter whose "tweaked deek" engines are still sought after by some of the Historic Formula Junior racers today.

Industria Argentina Santa Fe SA, Santa Fe, Argentina. 1959 - 1969

Initially a copy of the German Auto Union 1000 4 door saloon with a 3 cylinder 2-stroke engine of 980cc was produced. This was followed by the "Combi DKW Auto Union" which was a sporting coupe with coachwork designed by Fissore. It used the same 980cc engine.

Production figures were 21,797 for the 1000 and 700 for the sports coupe.
