In response to the demands of the German Ministry of War for its own armored cars, the Büssing company presented in 1915 the prototype of the Büssing A5P, the dimensions of which put all previously known armored vehicles in the shade.
Since the company Büssing already had several years of experience in the production of trucks, the engineers designed a heavily armored four-wheel drive vehicle, which was powered by a 90hp engine. Overall, the armored car had a dimension of 9.5 meters in length, 2.1 meters wide and 3.5 meters in height. It had a driver's seat at both ends as well as the equipment required for driving, thus allowing the vehicle to travel forwards and backwards without wasting much time.
A total of 11 hatches were available for machine guns, the crew consisted of 10 men including the commander, 1 mechanic, 2 drivers and 6 machine guns were.
Despite the all-wheel capability, the armored car moved too bumpy in the area .. also was the vehicle with 34km / h too slow, which meant that a series production was rejected by the War Department.
The three tanks already produced were still sent to the Eastern Front, where they were used in 1916 in Romania and from 1917 until the end of the war on the Russian front. The whereabouts of the 3 vehicles is unknown after the surrender.

German Panzers 1914–18 (New Vanguard)
Panzer warfare is synonymous with the Wehrmacht of World War II. This book examines the story of the Panzer's more mysterious ancestors, the little-known panzers of the Great War. Germany was very slow to develop armored vehicles compared to Britain and France. Early attempts such as the Marienwagen of 1915 were technical failures, discouraging further design efforts until the utility of the tank was proven by the British and French in 1916-17. Efforts to catch-up proved difficult, and only a couple dozen German A7V tanks were completed in time to take part in the final campaigns of 1918. As a result, the majority of German panzer units actually used captured British tanks, the Beutepanzer. This book will trace the development of German panzers of the Great War, including the A7V and its intended but unfinished stablemates. Also included will be an overview of the use of panzers by the German Army in World War I including both A7V and Beutepanzer units.
