Formally presented on opening of FIATs Mirafiori plant in May 1939, the AB 40 ended up being, at that time, one thing of a cutting-edge car. Because of innovative solutions such as for example dual drive and free wheels mounted as basic to help overcome obstacles, it had been a match for almost any international rival in identical class. The AB 41 version, introduced in 1941, included a few improvements, yet its main tool (a 20 mm Breda 35 cannon) remained equivalent. Effective at over 70 Kph on your way and almost 40 Kph off road (twice compared to other automobiles in the Regio Esercito), it proved effective in combat regardless of the defects due to use of bad materials into the armour and the complex 4-wheel steering system. It absolutely was later on replaced by the improved AB 43 variation
