The Austro-Daimler ADV is a passenger car of the upper class which was introduced in 1924 by the Austro-Daimler company as a successor to the AD 6-17.
The car was designed by a member of the Porsche staff called Karl Rabe. The engine had a light-alloy block and drove a camshaft through a vertical shaft.
The car had a front mounted 6-cylinder in-line engine that sent power the rear wheels via a 4-speed gearbox. The front wheels were attached to a rigid axle which had longitudinal leaf-springs. The rear wheels were also attached to a rigid axle but this had half-propped cantilever springs. The radiator was designed in a pointed shape to aid cooling.
In 1927, the ADV was terminated without a successor.
