The requirements for a new armored car for the Italian Colonial Police and the Italian Cavalry were combined into one specification.3,4,5
The four wheel steering did cause problems for the Autoblindas.4 There were two drivers in the crew as there were positions in the front and the rear that could drive the Autoblinda.3,4
The Autoblindas could be outfitted with extra wide sand tires for used in North Africa.4,5
There were also kits that could allow the Autoblindas to ride on railroad tracks.3,4 These could be changed in 30 minutes by the crew.4 These were primarily used in anti-partisan patrols in the Balkans.3
The first Autoblinda prototype appeared in 1939.3
Production started in 1940 with the AB 40.3,4 These were the most produced Italian armored car in World War II.4
The Autoblinda 41 was used in North Africa, the Soviet Union, Italy, and Hungary.
The Autoblinda 41s were used widely in the Balkans against partisans.5
