The AB 40 armoured vehicle ended up being devised the Italian Royal Army into the late 1930s, to change the old Lancia models. The automobile ended up being revolutionary at the time, being a four-wheel drive with split suspensions and two driving roles. The armoured automobile ended up being fitted with two 8mm device weapons into the turret and another into the back regarding the hull, but ended up being only built in little numbers for evaluation purposes, as growth of the greater amount of advanced AB 41 was already underway. Some of the models were changed into tracked patrol vehicles as the tires could be changed with rail wheels and relative braking systems. Many of these vehicles were found in Yugoslavia by the Italian forces and, later, by the Germans.
