Audi F103 - Evolution

Evolution

Initial changes were concentrated under the hood/bonnet where during the first two years of production the specification for the Solex carburetor was changed twice and in September 1967 the very high compression ratio was reduced from a (then) eye watering 1:11.2 to 1:9.1 which addressed serious "teething problems" with the engine as originally launched.

In September 1967 servo-assistance for the brakes became an option, the brakes on all but the basic model now being controlled using twin braking circuits, and by (in Germany) the final months of 1968 the range had settled down to three models, with the entry level Audi 60 powered by a 55 PS motor, the less basic Audi 75 producing 75 PS and the Audi Super 90 with 90 PS, able to challenge the performance image of some of the smaller BMWs.

Visually the car changed very little, but keen eyed observers would have noticed a discretely modernised rear from August 1970, with slightly larger rear lights and a reshaped bumper. The fuel filler moved from its location to the right of the license plate on the rear panel to a position on the right hand wing of the car, and following a general trend of the period was now shielded by a flap that was flush with the bodywork. Inside the 1970 upgrade also involved a reconfigured dashboard.
