The result of a collaboration agreement between Fiat and the Japanese automaker Mitsubishi Motors signed in 2014, the truck is mechanically identical to the fifth generation of the Mitsubishi Triton/L200, from which the engines also originate.

[1] The only changes from the L200 are the front grille and some interior finishing specifications, as well as customisations by Mopar.

It is sold in the Europe, the Middle East and Africa (EMEA) selling region, and was introduced at the Dubai International Motor Show on November 10, 2015.

The Fullback is only sold in the EMEA markets as Fiat already produces a pickup for the South American market which is not exported elsewhere, the Fiat Toro, which is similar in size to the Fullback but based on the monocoque chassis of the Jeep Renegade.

The Fullback for the European market is sold in rear-wheel drive or four-wheel drive configuration with a 2.4-liter Mitsubishi 4N15 diesel engine, available in two power variants, 150 PS (110 kW; 148 hp) and 181 PS (133 kW; 179 hp).
