The 600 model - the Grosser Mercedes - was introduced at the Frankfurt Auto Show in 1963. It restored the tradition of sumptuous luxury and ultimate prestige of Mercedes-Benz.A new V-type eight-cylinder engine of 6.3 liters (6,329 cubic centimeters) developing 250 horsepower (300 SAE) powered this newest edition of the great Mercedes to a maximum speed of 205 kilometers (127 miles) per hour. The 600 model was available in two body styles: a 5/6-seat limousine or 7/8-passenger pullman with wheelbases of 3,200 millimeters (126 inches) and 3,900 millimeters (153.5 inches), respectively. Overall length was 218 and 246 inches. From 1965 on, a landaulet also became available.
This fine automobile incorporated all modern design elements: fuel injection, overhead camshaft engine, air suspension and shock absorbers adjustment, disc brakes on all four wheels, automatic four-speed transmission and power steering, central vacuum locking system for the doors and luggage compartment, adjustable steering wheel, and two separate heating and ventilating systems. It was truly a majestic car of the highest order and an honorable descendant of the distinctive Great Mercedes automobiles of former years.
That year, 1963, the company offered fourteen passenger car models for sale. However, not all of them were made available to the American public, and most of them were naturally not entirely new models.
