The presentation of the 600 model at the International Motor Show in Frankfurt created real sensation. Since the new top model had been designed as an exclusive representative car, intended to fulfill the highest demands, it was serially equipped with many technical details, which taken together, stood for the highest standard that could be achieved in technological terms at the time.
For the first time in the history of Daimler-Benz, a V8 injection-engine was used which delivered maximum power of 250 hp from a 6.3-liter cubic capacity and maximum torque of 51 mkg. In connection with the standard automatic transmission this car achieved a driving perfomance, typical for a sports car. The 600 model, weighing almost two and a half tons, reached a maximum speed of of 205 kph (127 mph) and accelerated in 10 seconds from 0 to 100 kph (62 mph).
Shock absorbers, which could be adjusted at the steering column during the ride as well as air-pressure supported dual circuit brakes offered a maximum of safety. All four wheels were equipped with disk brakes. The front wheels had moreover been fitted with two double jaw brakes each.
The extremely generous basic equipment of the 600 model, air suspension, power brakes, central lock systems and an electronic heating and airing system afforded a maximum of ride comfort and easy handling. Unique hydraulics for extra comfort ensured automatic operation of the following functions: horizontal and vertical adjustment of the front seats, inclination control of the back of the seat, adjustment of the rear seats in longitudinal direction, opening and closing of the vehicle doors, the boot lid, the optional sliding sunroof as well as of the side windows.
Serial production of the “Grand Mercedes” began in September 1964. Apart from a five- and six-seated sedan with 3200 mm (126 in) wheelbase, three seven- and eight-seated Pullman versions with 3900 mm (154 in) wheelbase were available: a four-door Pullman limousine with rear seating in a face-to-face arrangement, a six-door Pullman limousine with rear seats and additional folding tables in driving direction and a Pullman landaulet. The last was available in four different versions.
The standard version had four doors, rear seating in a face-to-face arrangement and a hood, reaching to the front edges of the rear doors. As a special design, a six-door version with rear seats and additional fold-down chairs in driving direction was also available. As with the six-door Pullman limousine, the doors in the middle could also be ordered without handles. Both landaulets, the four-door as well as the six-door version were also available with an long hood, which extended to the middle partition.
Even more exclusive than the landaulets were the special security sedans and Pullman limousines. Like the landaulets, they were not included in any price list. The first bullet-proof vehicle by Daimler-Benz after the war was built in June 1965; this was a Pullman limousine with an elevated roof. It had many special security features and like some other ordinary Pullman limousines, had not been ordered by a customer but remained part of Daimler-Benz’ motor vehicle fleet to be hired out to the government or to other potential users. Another car of this type was completed in 1980, which also remained at Sindelfingen.
