In November 1885, Gottlieb Daimler's son, Adolf, successfully drove a "riding car" along a three-kilometre test run between Cannstatt and Untertürkheim.
In the summer of 1886, Daimler and Maybach integrated their engine in a carriage and completed successful test runs between Esslingen and Cannstatt. At the same time, the engine was also fitted into what was effectively the world's first motorboat (it was named "Neckar"). It quickly became apparent that the greenhouse – the birthplace of the automobile – was not big enough. In June 1887, Daimler moved to new production facilities in Seelberg.
