The Fiat Fullback Extended Cab LX 2.4d AWD, launched in 2017, represents Fiat’s entry into the one-tonne pickup truck segment. Developed in collaboration with Mitsubishi Motors, the Fullback is essentially a rebadged version of the Mitsubishi Triton. The Extended Cab configuration, featuring two doors and seating for four, aimed to provide a balance between practicality and passenger comfort. This particular LX 2.4d variant, equipped with a 2.4-liter diesel engine producing 181 horsepower and all-wheel drive, was positioned as a mid-range offering within the Fullback lineup, targeting both commercial and recreational users. It was primarily sold in markets outside of North America, where Fiat had limited presence in the pickup truck sector.

Powertrain & Engine Architecture
The Fiat Fullback LX 2.4d is powered by the Mitsubishi 4N15 2.4-liter inline-four cylinder diesel engine. This engine, a mainstay in Mitsubishi’s lineup, utilizes a common-rail direct injection system and a turbocharger with an intercooler to deliver a balance of power and efficiency. The 4N15 engine is known for its relatively robust construction and is designed to meet stringent Euro 6 emission standards, incorporating a diesel particulate filter (DPF) to reduce particulate matter emissions. The engine produces 181 horsepower at 3500 rpm and a substantial 430 Nm (317 lb-ft) of torque at 2500 rpm. The transmission is a six-speed manual gearbox, chosen for its durability and driver engagement. The all-wheel-drive system allows for selectable modes, including 2H (rear-wheel drive), 4H (high-range four-wheel drive), and 4L (low-range four-wheel drive), providing versatility for both on-road and off-road conditions.
Driving Characteristics
The 181 hp 2.4d powertrain in the Fullback Extended Cab delivers adequate performance for typical pickup truck duties. While not exceptionally quick, the engine provides sufficient torque for hauling and towing. The six-speed manual transmission allows for precise control, but the gear ratios are geared more towards fuel efficiency and load-carrying capacity rather than outright acceleration. Compared to higher-output versions of the Triton (or potential future Fullback variants), this engine offers a more economical driving experience. The all-wheel-drive system enhances traction, particularly on loose surfaces, but adds to the overall weight of the vehicle. The ride quality, typical of a body-on-frame pickup, is firm but generally comfortable for everyday use.
Equipment & Trim Levels
The LX trim level of the Fullback Extended Cab offered a reasonable level of standard equipment. Interior features typically included air conditioning, power windows, central locking, and a basic audio system with USB connectivity. The interior upholstery was generally durable cloth. Optional extras available for the LX trim could include alloy wheels, a touchscreen infotainment system, and rear parking sensors. The Extended Cab configuration provides limited rear seating, best suited for occasional passengers or short trips. The dashboard layout is functional and straightforward, prioritizing practicality over aesthetic design.
Chassis & Braking
The Fiat Fullback utilizes a traditional body-on-frame construction, providing a robust and durable platform for hauling and towing. The front suspension consists of double wishbones, while the rear suspension employs a torsion beam setup. This configuration balances ride comfort with load-carrying capacity. The braking system features ventilated discs on the front wheels and drum brakes on the rear. Anti-lock Braking System (ABS) is standard. The steering is rack and pinion with electric power assistance, providing reasonable steering feel and maneuverability.
Market Reception & Comparison
The Fiat Fullback, and specifically the 2.4d LX AWD variant, received mixed reviews. Critics generally praised its robust construction, capable all-wheel-drive system, and competitive pricing. However, some reviewers noted that the interior felt dated compared to more modern pickup trucks, and the engine, while adequate, lacked the refinement of some competitors. Fuel economy was generally considered acceptable for a vehicle of its type, averaging around 7.1 l/100 km (33.1 US mpg). Compared to other trims in the Fullback lineup, the 2.4d LX offered a good balance between performance, fuel efficiency, and price, making it a popular choice for buyers seeking a practical and versatile pickup truck.
Legacy
The Fiat Fullback, while not a long-term success for Fiat, represents an interesting chapter in the brand’s history. The 4N15 engine has proven to be relatively reliable, and well-maintained examples continue to be found on the used car market. The simplicity of the powertrain and the robust construction of the chassis contribute to its long-term durability. However, potential buyers should be aware of the maintenance requirements of the diesel particulate filter (DPF) and the potential for wear and tear on the suspension components. The Fullback remains a viable option for those seeking an affordable and capable pickup truck, particularly in regions where Fiat had a stronger presence.
