F103 is 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 that had been dormant since before the Second World War.
Models
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 PS).
The more powerful Audi 80 and Audi Super 90 sports saloons (with 80 and 90 PS respectively) appeared in 1966: in 1968 the arrival of the less powerful Audi 60 completed the range. Breaking somewhat with the naming pattern, the Audi 60 has 55 PS, although export versions produce 65 PS.
The Audi 75 replaced both the Audi 72 and the Audi 80 from 1969 onwards.
In 1972 the F103 series was discontinued in favour of the "B1" Audi 80.
