The Austro-Daimler AD 6-17 was introduced in 1921. It is a passenger car of the upper class that was produced by Austro-Daimler. It was the first car design from the company that was released after the First World War.


The term "6-17" came from the car's 6-cylinder engine which produced 17-horsepower. The car was designed by Ferdinand Porsche and the engine block was made ​​of a light metal alloy.

The car had a front mounted 6-cylinder in-line engine that powered the rear wheels via a 4-speed gearbox. The front wheels were attached to a rigid axle that had longitudinal leaf-springs. The rear wheels were also attached to a rigid axle, but this had cantilever springs. The radiator was pointed in shape to aid cooling. The foot brake acted on the drive shaft and the rear wheels.

In 1924, the AD 6-17 replaced with the ADV.
