Mercedes-Benz’s first supercharged eight, built for people who did not drive themselves.
The Typ 770 replaced the six-cylinder Typ 630 in 1930 as the largest and costliest car the company made: 5.6 meters long, and a bare chassis at 29,500 Reichsmark when the Pullman saloon built on it listed at 38,000. The straight-eight used 95 × 135 mm cylinders, a camshaft in the block operating overhead valves, a three-jet twin carburetor and two plugs per cylinder fed by magneto and battery. Three speeds and a semi-automatic vacuum overdrive took it to 150 km/h.
Engaging the Roots blower lifted output from 150 to 200 PS and the car to 160 km/h, which was remarkable for 2,700 kg of state carriage. State carriage is the right description: the abdicated Kaiser Wilhelm II took delivery of a Cabriolet F in January 1931, and Hindenburg, Hirohito, Pius XI, Pius XII and Hitler all used one. Only 117 were built up to 1938, when the longer W 150 took over with the same engine and 13 cm more wheelbase.
