The Fiat Fullback Double Cab 2.4 (154 Hp) 4WD Automatic was a mid-size pickup truck produced by Fiat between 2016 and 2017. It represented Fiat’s entry into the competitive one-ton pickup segment, primarily aimed at markets outside of North America. The Fullback was essentially a rebadged version of the Mitsubishi Triton, a result of an OEM agreement between the two manufacturers. This particular variant, featuring the 2.4-liter diesel engine paired with a five-speed automatic transmission and four-wheel drive, occupied a mid-range position within the Fullback lineup, offering a balance between capability, comfort, and affordability. It was designed to appeal to buyers needing a versatile vehicle for both work and family use.

Powertrain & Engine Architecture
The Fiat Fullback 2.4 utilized Mitsubishi’s 4N15 2.4-liter four-cylinder diesel engine. This engine is a common-rail direct injection (CRDI) unit, employing a turbocharger with an intercooler to boost power and efficiency. The 4N15 engine is known for its robust construction and relatively simple design, contributing to its durability. The engine produces 154 horsepower at 3500 rpm and 380 Nm (280 lb-ft) of torque at 2500 rpm. The five-speed automatic transmission, also sourced from Mitsubishi, was chosen for its ease of use and suitability for a wider range of drivers. While not the most modern automatic available at the time, it provided smooth shifts and adequate performance for typical pickup truck duties. The engine is longitudinally mounted, a common configuration for four-wheel-drive vehicles, and drives all four wheels through a selectable 4WD system.
Driving Characteristics
The 2.4-liter engine and five-speed automatic combination in the Fullback Double Cab delivered adequate, but not exceptional, performance. Acceleration was reasonable for a vehicle of its size and weight, but it wasn’t particularly quick. The automatic transmission, while smooth, sometimes felt hesitant during downshifts, especially when fully loaded. The gear ratios were tuned more for fuel economy and towing capacity than for outright speed. Compared to a manual transmission version, the automatic offered less driver engagement but greater convenience. Higher-output versions of the Fullback, such as those with more powerful diesel engines, provided noticeably quicker acceleration and more responsive performance. The 4WD system provided good traction in off-road conditions, making it suitable for light to moderate off-roading tasks.
Equipment & Trim Levels
The Fullback Double Cab 2.4 4WD Automatic typically came with a reasonable level of standard equipment. This included air conditioning, power windows and locks, a basic audio system with USB connectivity, and ABS brakes. Interior upholstery was typically cloth, with durable plastic trim. Optional extras included alloy wheels, a touchscreen infotainment system with navigation, and a reversing camera. The Double Cab configuration offered seating for five passengers, with a spacious rear cabin. The dashboard layout was functional and straightforward, prioritizing usability over aesthetics.
Chassis & Braking
The Fullback Double Cab featured a body-on-frame construction, typical of pickup trucks, providing a robust and durable platform. The front suspension utilized independent coil springs, offering a comfortable ride on paved roads. The rear suspension employed leaf springs, which were better suited for carrying heavy loads. Braking duties were handled by ventilated discs at the front and drum brakes at the rear. While adequate for most driving situations, the rear drum brakes were a cost-saving measure and didn’t offer the same stopping power as disc brakes. The steering system was a rack and pinion setup, providing precise and responsive steering.
Market Reception & Comparison
The Fiat Fullback was generally well-received as a capable and affordable pickup truck. Critics praised its robust construction, comfortable ride, and spacious interior. However, some reviewers noted that the automatic transmission could be slow to respond and that the engine lacked the refinement of some competitors. Compared to other pickups in its class, such as the Toyota Hilux and Ford Ranger, the Fullback offered a competitive price point but lacked some of the advanced features and sophisticated technology. Fuel economy was respectable, averaging around 32.7 US mpg in combined driving. Reliability was generally good, benefiting from the proven Mitsubishi Triton platform.
Legacy
The Fiat Fullback’s production run was relatively short-lived, ending in 2017. However, the 2.4-liter diesel engine and five-speed automatic transmission combination proved to be reasonably reliable. On the used car market, Fullbacks are often sought after for their affordability and practicality. The 4N15 engine is known for its longevity, provided it has been properly maintained. While not a groundbreaking vehicle, the Fiat Fullback Double Cab 2.4 4WD Automatic provided a solid and dependable option for buyers seeking a versatile pickup truck.
