The Mercedes-Benz 770, also known as the Großer Mercedes (large Mercedes) was a luxury automobile built by Mercedes-Benz from 1930 to 1943. It is probably best known from archival footage of high-ranking Nazi officials before and during World War II, including Adolf Hitler and Hermann Göring.
The 770 was introduced with the internal code W07 in 1930. These cars were mainly used by governments as state vehicles.
The W07 version of the 770 was powered by an inline eight cylinder engine of 7,655 cc (467.1 cu in) capacity with overhead valves and aluminium pistons. This engine produced 150 brake horsepower (110 kW) at 2800 rpm without supercharging. An optional Roots type supercharger, which was engaged at full throttle, would raise the output to 200 brake horsepower (150 kW) at 2800 rpm, which could propel the car to 160 km/h (100 mph). The transmission had four forward ratios, of which third was direct and fourth was an overdrive.
The W07 had a contemporary boxed chassis suspended by semi-elliptic leaf springs onto beam axles front and rear. Dimensions would vary with coachwork, but the chassis had a wheelbase of 3,750 mm (147.6 in) and a front track equal to the rear track of 1,500 mm (59.1 in).
117 W07-series cars were built.
The 770 was substantially revised in 1938, resulting in the new internal designation of W150. The all-new chassis was made with oval section tubes and was suspended from coil springs all around, with independent suspension at front and a de Dion axle at the rear.
The engine had the same basic architecture as that of the W07, but it had been tuned to produce 155 brake horsepower (116 kW) at 3000 rpm without supercharging and 230 brake horsepower (170 kW) at 3200 rpm with. The transmission now had five forward ratios with a direct fourth gear and an overdrive fifth.
In 1938 the Mercedes 770 is thought to have been the most expensive German passenger car offered for sale up to that time, though it appeared on no price list: the price...

When the Mercedes-Benz Type 770 was presented at the Paris Automobile Show in the autumn of 1930, this “Grand Mercedes” far outstripped the familiar dimensions in the category of high-quality, high-performance luxury automobiles. Right off the bat, it set a new standard in the world of top-flight passenger cars for prospective customers, the public and the experts. Internally designated W 07, the car indeed was the largest and, in every respect, most luxurious Mercedes offered by Daimler-Benz to its customers, costing the price of a single-family home, but in return featuring an ultramodern 200 hp supercharged engine and a “Sindelfingen body” with sensational appointments and an exquisite finish.
7.7-liter in-line eight-cylinder with fine ingredients
The engine offered a number of exceptional features to a technically extremely well-versed clientele. The cylinder block of the voluminous (displacement 7655 cm3) in-line eight-cylinder engine, made of extremely wear-resistant chrome-nickel-alloyed gray cast iron, was combined with a heavily ribbed crankcase bottom half incorporating an integral oil pan made of electron metal. Carefully balanced statically and dynamically, the chrome-nickel steel crankshaft with solid-forged counterweights ran in nine main bearings and additionally had a progressively acting vibration damper at its front end to ensure even smoother and quieter running of the power plant, internally called the M 07.
It went without saying that such an engine could not have a simple side-valve configuration. The overhead valves in the gray iron cylinder head were actuated by means of roller tappets, push rods and rocker arms controlled by a side camshaft running in nine bearings.
Updraft dual-barrel carburetor, accelerator pump and cold-starting aid were the most important components of the energy supply system, supported by a light-alloy inlet manifold automatically heated by exhaust gas and thermostat controlled hot-air flaps. The ignitio...
