Auto Car | Mercedes-Benz Type 770 Grand Mercedes | The next vehicle which Mercedes-Benz offered in a version with factory-integrated armour was the Type 770 "Grand Mercedes" which was launched in 1930. Notable characteristics of this model included rigid front and rear axles, which were attached to a ladder frame consisting of U-section‑profiles by means of semi-elliptical springs, as well as a 7.7-litre eight-cylinder in-line engine with an output of 150 hp (200 hp with a supercharger). Between March 1932 and January 1935, the Japanese imperial court took delivery of at least six "Grand Mercedes" models in Pullman limousine guise. At least one of them was armoured and has been in the Mercedes-Benz Museum collection since 1971
An enhanced version of the "Grand Mercedes" with a sophisticated swing-axle suspension was presented in 1938. The perimeter frame of this model consisted of thin-section oval tubes which combined great rigidity with low weight. Independent double-wishbone front suspension and‑a rear De Dion axle represented additional improvements. The engine, the technical characteristics of which were largely based on the predecessor model, developed 230 hp with a supercharger.
The "Grand Mercedes" was officially available as a Pullman limousine, as Cabriolet D and Cabriolet F models and as an open touring car. A number of special armoured versions of each of these body variants were built. Furthermore, the state commissioned armoured four-door limousines between June 1943 and July 1944. Whereas the permissible gross vehicle weight of the standard cars was 4200 kg, this figure increased to as much as 5420 kg in the case of the armoured versions. However, the maximum speed of the latter was reduced from 170 km/h to 80 km/h in order to maintain the service life of the tyres.
