The Zeppelin-Maybach Gearless Car

In the fall of 1921 Maybach exhibited for the first time the 22-70 horsepower gearless motor car, designed to simplify operation. Only what is termed the direct speed is used in driving; except for grades of more than 10%, and for the starting on these grades, when apart from the rest of the mechanism a single gear is used by pushing down a pedal. When it is released, the direct grip is automatically restored without noise or vibration. Backing is accomplished with the electric starting motor by means of a pedal. Smaller cars of this type are now under construction.
