The Mercedes-Benz 770, also known as the Großer Mercedes (large Mercedes) was a large luxury car 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, Hermann Göring, Heinrich Himmler and Reinhard Heydrich.

The 770 was introduced as successor of the Mercedes-Benz Typ 630 with the internal code W07 in 1930. These high-priced cars were mainly used by governments as state vehicles. Reich President Paul von Hindenburg, Emperor Hirohito and Pope Pius XI were among the customers, Adolf Hitler used a 770 from 1931 onwards. 117 W07-series cars were built until 1938.

The W07 version of the 770 was powered by an inline eight-cylinder engine of 7,655 cc (467.1 cu in) capacity with an overhead camshaft 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 (99 mph). The transmission had four forward ratios, of which third was direct and fourth was an overdrive (mechanics).

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).
