In 1959 came the first revision. The model Steyr-Puch 500 D was provided with the metal roof produced by Fiat (D for Dach, i.e. "roof" in German), and in addition to that the luxury model 500 DL was equipped with a stronger engine (20 hp/15 kW). 1961 saw the launch of two estate models, 700 C (C for Combi) and 700 E (E for Economy), both featuring a larger 643 cc engine but with different power ratings. In 1962 the sedan, too, was equipped with the larger engine, leading to the 650 T (T for Thondorf, the location of the manufacturing plant in Graz).
