'F103' was the internal designation for a series of car models produced by Auto-Union in West Germany from 1965 to 1972, derived from the earlier DKW F102. To signify the change from a two-stroke to four-stroke engine, the DKW marque was dropped in favour of Audi, a name which had lain dormant since the Second World War.
The first model was launched simply as the 'Audi', later being renamed the 'Audi 72' (72 being the nominal power output of the engine in ''Pferdestärke''), as further F103 series models were introduced.
In 1972 the F103 series was discontinued in favour of the "B1" Audi 80.

The engines of the F103 series were a joint development with Daimler-Benz who owned Auto-Union at the time (from 1958 to 1964). They were dubbed the ''Mitteldruckmotor'' (medium pressure engines), because of their unusually high compression ratio, mid-way between conventional petrol and diesel engines.

Bodywork

The F103 bodyshell was a development of the earlier DKW F102. The engine compartment had to be extended so that the new four-cylinder engine could be accommodated. The front and tail were also cosmetically revised.
All models were offered as saloons with two and four doors. With the exception of the Audi Super 90, the F103 series were available also as three-door estate model. This was called, like the estate models of Volkswagens, ''Variant''.
