Mercedes W191 Service Repair Manuals

In January 1952 the Mercedes-Benz W191 170 Sb replaced the W136 170 S model. The Mercedes-Benz W191 170 Sb and 170 DS were luxury cars produced by Mercedes-Benz from 1952 until 1953 in gasoline and diesel powered forms. Jump to Manuals

The “Mercedes-Benz W191170 Sb was available only with a four-door sedan/saloon body. Other changes included in the 1952 upgrade included the replacement of the floor-mounted gear lever with a then fashionable column mounted gear lever. There was now a starter button on the dashboard and the heater was improved. Under the bonnet/hood the camshaft was now driven via a chain rather than via gear cogs, a hypoid differential was fitted and the rear track was increased by 15 mm (0.59 in).

It was initially offered with a 1.8 liter version of the 1.7 liter inline-four cylinder M136 engine used in the slightly smaller production type 170 V. It was the first Mercedes-Benz to carry in its name the suffix “S” (for Sonder modell (Special model) denoting a superior level of comfort and quality. As such, its intended market was successful business owners and company directors.

The first 170 S upgrade occurred in January 1952, being further distanced from the 170 V with its own chassis number W191. Mercedes' introduction a year earlier of the 2.2 liter six cylinder M180 engine Mercedes-Benz W187 luxury 220 model, positioned between the 170 S and the company flagship 3.0 liter Mercedes-Benz W186 Adenauer tourers undermined the four cylinder 170 S's luxury niche.

January 1952 also saw the launch of a diesel powered version of the 170 S, sold as the Mercedes-Benz 170 DS and carrying, like its gasoline/petrol powered sibling, the works designation „W 191“. It shared the 40 HP (29 kW; OM 636 diesel power unit of the diesel powered 170 V and came with the same official top speed of 105 km/h (65 mph)..
