The driver was seated at the front, with very good overall vision consisting of a large port forward and small lateral loopholes.

The mechanical layout was also interesting and innovative, comprising a FIAT Aviazione A12, water-cooled 240 hp (180 kW) engine with 6 cylinders driving the tracks through a transverse transmission.

Armament originally consisted of the turret mounted gun and ten machineguns (three on each side and four in front), but this left the rear of the tank undefended and tended to contaminate the interior with propellant fumes, so it was decided to install a ventilator in the roof and alter the machinegun positions to two on each side, three at the rear, and two in front.

While technically a heavier tank design, no prototypes of the German K-Wagen, were completed before the end of World War I.

In Libya, the FIAT tank proved capable of an average speed of 4 km/h, and so, after two months its career ended, being unable to keep up with rapid movement of the enemy.

The surviving FIAT 2000 at Rome was left in a depot for several years, until it was sent on the orders of Colonel Maltese to Forte Tiburtino, nearly catching fire during travel.

From June 2017 to October 2018 the committee worked on remaking a complete set of blueprints, after which the construction of the replica started on 15 November 2018.
