Mercedes 770 W07: Unveiled at the 1930 Paris Motor Show, the Mercedes was an elegant, yet slightly conservatively designed super-luxury automobile. It was the largest model Daimler-Benz<\/a> had produced to date and quickly earned the nickname “Grosser”. <\/p>\n\n\n

The 770<\/a> (internal code W07) was powered by an eight-cylinder<\/a> inline engine that displaced 7.7 liters and produced 150 bhp. With the optional supercharger<\/a> engaged its output rose to 200 horsepower. The supercharger was a popular option and most cars were fitted with it. Only 13 buyers opted for the normally aspirated engine.<\/p>\n\n\n

The wheelbase offered an ideal platform for coach-built models<\/h2>\n\n\n\n

At close to 3,750 mm, the wheelbase provided an ideal platform for the creation of bespoke coach-built bodies. They were completely tailored to the individual customer’s desires. Many of them were built in-house in Sindelfingen.<\/p>\n\n\n\n

The engine incorporated numerous advanced features. Made of wear-resistant chrome-nickel-alloy grey cast iron, the cylinder block was combined with a heavily ribbed crankcase. It incorporated an integral oil pan made of Elektron magnesium alloy. <\/p>\n\n\n\n

No practical side valve engine could produce the required power. So the Mercedes 770 W07<\/a> unit used overhead valves actuated by means of roller tappets, pushrods and rocker arms controlled by a side camshaft running in nine bearings.<\/p>\n\n\n

These exhaust pipes became more famous with the 500K and 540K models<\/em><\/p>\n\n\n\n

The Mercedes 770 W07 engine was available with and without compressor<\/h2>\n\n\n\n

The low-compression (4.7:1) long-stroke engine developed its 150 horsepower at a modest 2,800 rpm. Its maximum torque of approximately 392 Nm (289 lb\/ft) arrived at only 1,200 rpm. Despite weighing some 3.5 tons, the 770 was capable of reaching 150 km\/h (93 mph). But this was deemed insufficient by the majority of the super wealthy customers, who could afford it. That is why the optional supercharger was offered. <\/p>\n\n\n\n

Costing as much as a medium size family car, the Roots<\/a> blower was fitted with exhaust pipes sheathed in flexible metal hose. They projected from the right-hand side of the hood. This was done for better heat dissipation. But at the same time it also served as a status symbol. With the blower installed, maximum power increased, as already mentioned, to 200 bhp at the same engine speed. The torque increased to a mighty 535 Nm (395 lb\/ft) at 1,500 rpm. The top speed rose to 160 km\/h (99 mph).<\/p>\n\n\n

Most bodies were built in-house<\/h2>\n\n\n\n

As already mentioned, the majority of bodies were provided by Mercedes-Benz’s popular in-house coachbuilding facility, Sindelfingen. This enabled the Mercedes 770 W07<\/a> to be delivered complete. It was an almost unheard of state of affairs in an age when bespoke bodies by independent coachbuilders were the norm for luxury cars.<\/p>\n\n\n\n

In the course of the production span over eight years, the body design underwent various changes. It was first a rather box-shaped with upright windscreen, similar to designs that were popular in the 1920s. Later this evolved into more appealing coachwork with flowing lines and raked front screens. <\/p>\n\n\n\n

A visual signature feature was the wedge-shaped pointed radiator. It afforded both vehicle and owner an impressive aura. The high ride comfort and quality standard of the 770<\/a> made a significant contribution to the global acceptance of the Mercedes-Benz brand.<\/p>\n\n\n

These three Pullman photos should demonstrate, how the body design evolved from 1930 to 1938. The car on top is from 1931 and the second one from 1935. The third one is from 1938.<\/em> This last design was later also taken over by the 770<\/a> successor with the same name<\/em><\/p>\n\n\n
