Mercedes-Benz 170S

The Mercedes-Benz 170 S was a luxury car built by Mercedes-Benz from 1949 until 1955 in petrol and diesel versions. It began as a 1.8 litre development of the four-cylinder M136 engine used in the smaller 170 V, and was the first Mercedes-Benz to carry the suffix S, for Sonder modell or special model, marking a higher level of comfort aimed at business owners and company directors. It was released in May 1949, was reworked in January 1952 with its own W191 chassis number, and was discontinued as the 1953 Ponton 180 arrived, leaving the cheaper 170 S-V and the diesel 170 S-D until 1955. Late in its life more than 80 percent of sales were diesel, mostly to taxi operators.
