1938 MERCEDES BENZ “Grosser Mercedes” Cabriolet D (W150) 770 Kompressor

Vehicle Overview

Mercedes-Benz introduced the second generation of the “Grand Mercedes” at the 1938 Berlin Automobile and Motorcycle Show, where the three-pointed star stand shined brightly.

It was an important event for the German carmaker. Not only because a man named Adolf Hitler opened the show, but also because its stand hosted Caracciola’s record-breaking car that reached 271 mph (436 kph) and, inevitably, it attracted everyone. Mercedes-Benz unveiled the W150 model, also known as the Grosser Mercedes (Grand Mercedes), in the same stand. A range of cars built for the new government officials and for those who could afford them. Besides the closed versions and the Pullman limousine, the three-pointed star brand showcased the Cabriolet D.

Mercedes built the W150 using Grand Prix technology with independent front suspension and rear DeDion axle with coil springs. The carmaker fully revealed that system on a bare-chassis displayed at the carmaker’s booth. With the Cabriolet D version, the carmaker tried offering more open-top versions for its customers. It featured a front fascia with a V-shaped grille for the radiator, like the rest of its W150 stablemates. However, unlike the Grand Tourer version, it featured a shorter wheelbase. As a result, it was lighter and, thus, faster.

Inside, the Cabriolet D could get up to five occupants since the gear-stick was on the floor and prohibited a third person from staying at the front. The large canvas roof took its place behind the cabin, above the trunk, which was only accessible from the outside. Mercedes installed the spare wheel behind the front wheel arches to keep an elegant look for the car’s back.

Under the hood, the carmaker installed a supercharged engine that produced 230 hp paired with a five-speed manual transmission. As a result, the unofficial maximum speed for the Cabriolet D exceeded 100 mph (161 kph).
