The Mercedes-Benz W 153 was a luxury six cylinder passenger car built in parallel with the W 143 from 1938, and first presented in public at the Berlin Motor Show early in 1939.

Despite the slightly larger engine size and the inclusion of two twin chamber Solex 30 JFFK carburettors, claimed power was unchanged at 55 PS (40 kW): the compression ratio was set at the relatively low value of 1 : 6.6.

[3] The four-speed manual transmission incorporated synchro-mesh on all four forward ratios, and power was delivered to the road via the rear wheels.

[3] There was no long cabin „Pullman-Limousine“ version of the car, and the large external rear mounted luggage racks that were a feature of the W143 were not repeated on the W153.

W153s were built until 1943, but only 87 of these emerged from the plant in 1942 and 1943, due to the changed government priorities accompanying the wartime economy.
