The Horch 11/22 PS was a car that was produced between 1906 and 1909.
One of the best known motorsports events at the time was the "Prince Henry Run". This was a motorsports even that had been initiated by the brother of the German Kaiser.
August Horch commissioned the coachbuilder Kathe in Halle to build two 22 hp Horch cars with a torpedo-sports car body to participate in this reliability rally. The model was given the name 11/22 hp which was derived from the car tax system employed from 1906. 1 tax-hp was the equivalent to a displacement of just under 250cc. With this in mind, the name originated with the combination of tax-hp (11) and engine-hp (22).
The 11/22 PS then went into production where it was fitted with a four-cylinder inline engine which had a displacement of 2725cc. It had a maximum power output of 22hp at 1,400 rpm giving the car a top speed of 85 km/h.
A total of 307 cars were made, selling at 9,800 marks for a bare chassis.
