Technical
The Auto Union's 981 cc two-stroke three-cylinder engine came in various states of tune. After 1960, advertised power in the saloon versions was increased to 50 bhp (37 kW). Power was delivered via a four-speed manual gear box, controlled using a column-mounted lever. The electrical system was a six-volt one which by this time was beginning to look old fashioned.
1961 saw the introduction of the so-called Clean Oil Regulator “Frischölautomatik”, a system incorporating a separate oil tank and pump to dispense the oil which, in a two-stroke engine, is mixed with the fuel ahead of combustion. The stated purpose was to reduce the characteristic blue smoke emission for which the car was known. This was to be achieved by ensuring that oil was introduced in exactly the correct 1:40 proportion to the fuel, and the device was advertised as a way to improve engine longevity. The timing of this innovation proved unfortunate The 1962/63 winter was an exceptionally cold one in Europe. The Auto Union 1000 model experienced an unexpected increase in crankshaft damage because the oil, its viscosity affected by the cold weather, was unable to flow freely through the narrow feeder pipe in the carburettor.
