The Audi 100, in general, was in its fourth American model year for 1973 with base, LS, and GL trim. But as of ’74, 100LS was the sole trim level and model name. It was marketed here as a midsize car. Wheelbase was small for the time at 105.3 inches. New in ’73 was a redesigned rear suspension that was now coil-sprung rather than the previously used torsion springs. It was sold here only in two door coupe and 4-door sedan styles.
Powering one of these was a 1871cc I4 making 91hp. Available transmissions were a 4-speed manual or 3-speed Volkswagen automatic. Motivation was supplied by the front wheels.
As far as we can tell, the 100LS was sold in the U.S. through model year 1977. This version stopped after 1976 for the rest of the world, as it was updated. The U.S. version hung on one more year. Our next version became the Audi 5000 for 1978.
