In the spring of 1908, Daimler-Motoren-Gesellschaft (DMG) launched the new 35 hp model – Daimler’s first car with propeller shaft drive. This type of power transmission from the gearbox to the driven axle via a shaft with universal joints was the most important innovation of the new Mercedes model. The engine, by contrast, was adopted in almost unmodified form from the previous 35 hp model with chain drive. It consisted of two rows of cylinder pairs arranged in line, and it had lateral camshafts and upright valves. From 1908, the 35 hp model advertised as “cardan car” ushered in the gradual replacement of power transmission by chains between engine and axle at DMG. However, chain drive was to remain in the range of the Stuttgart-based manufacturer, parallel to propeller shaft drive, for several years to come. In particular, heavy and powerful cars continued to be fitted with chain drive which was considered to be more comfortable.
