Mercedes-Benz 770K Cabriolet
The Mercedes-Benz 770 K on exhibit in the Technik Museum Sinsheim was delivered to the Reichskanzlei in 1938 to serve for representation purposes. Technologically, the massive automobile that was employed in many parades of the time, was absolutely state-of-the-art. So did the design of the chassis e.g. employ various developments derived from the construction of racing cars.
To protect the passengers from assassination attempts the car had a mine-proof armor clad floor. In addition, it was equipped with windowpanes composed of several centimeters of bullet-proof glass armored doors as well as a retractable armor plate behind the rear seats. Where as the cabrio sott top, in the nature of things does not have any possibilities to be armor clad.
This predicament as well as the fact that Hitler used to ride in parades with the top down, and in addition to that liked to stand in an upright position seem to render these precautions more than dubious considering that they would have offered any protection below the waistline only. The car was propelled by a colossal 8-cylinder supercharged in-line engine with a displacement of 7.6 liters which produced an output of 230 hp already at a mere 3200 rpm. In spite of the enormous weight caused by the massive armoring this enabled the car to reach a maximum speed of 140 km/h, no less.
