The "W188" Type 300 S was Mercedes-Benz's top-end vehicle on its introduction at the Paris Salon in October 1951.
The Type 300 S came as a 2+2 coupe, cabriolet (with landau bars) (officially Cabriolet A),
or roadster.
Although mechanically similar to the contemporary W186, the largely hand-built W188 was marketed as one of the top luxury cars in the world.
7.8:1 compression and triple Solex carburetors raised engine output to 150 PS (148 hp/110 kW) at 5000 rpm.
