Formally presented at the opening of FIATs Mirafiori plant in-may 1939, the AB 40 had been, during the time, something of a cutting-edge car. As a result of innovative solutions particularly double drive and extra wheels mounted as neutral to greatly help get over obstacles, it absolutely was a match for any international rival in identical class. The AB 41 variation, introduced in 1941, included a few improvements, yet its main gun (a 20 mm Breda 35 cannon) stayed the exact same.
