The Fiat Fullback Double Cab 2.4 (181 Hp) 4WD S&S was a mid-size pickup truck produced by Fiat between 2016 and 2017. It represented Fiat’s entry into the competitive one-tonne 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. The “Double Cab” designation indicates a four-door configuration with seating for five passengers, offering a balance between passenger comfort and cargo capacity. The 2.4-liter engine with 181 horsepower and the 4WD system with Start & Stop (S&S) technology positioned this variant as a versatile option for both work and recreational use.

Powertrain & Engine Architecture
The Fiat Fullback 2.4 4WD S&S 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 181 horsepower at 3500 rpm and a substantial 430 Nm (317 lb-ft) of torque at 2500 rpm. The Start & Stop system, indicated by the “S&S” designation, automatically shuts off the engine when the vehicle is stationary (e.g., at traffic lights) to reduce fuel consumption and emissions. The engine is longitudinally mounted, and power is delivered to all four wheels through a six-speed manual transmission. The transmission’s gear ratios were tuned to provide a balance between on-road drivability and off-road capability.
Driving Characteristics
The 2.4-liter engine, while not exceptionally powerful, provided adequate performance for most everyday driving situations. The 430 Nm of torque delivered a strong low-end pull, making it suitable for hauling loads or navigating challenging terrain. Compared to potential higher-output versions (which weren’t widely available in the Fullback lineup), this variant prioritized fuel economy and ease of use over outright speed. The six-speed manual transmission allowed for precise control, but the shift quality wasn’t particularly sporty. The 4WD system offered selectable modes (2H, 4H, 4L) allowing the driver to adapt to varying road conditions. In real-world conditions, the Fullback 2.4 felt competent on paved roads, but its true strength lay in its off-road capabilities and its ability to handle heavy loads.
Equipment & Trim Levels
The Fullback Double Cab 2.4 4WD S&S typically came with a reasonable level of standard equipment. This included air conditioning, power windows, central locking, and an audio system with USB connectivity. Safety features such as ABS (Anti-lock Braking System) and multiple airbags were also standard. Interior upholstery was typically cloth, with a functional and durable design. Optional extras could include alloy wheels, a navigation system, and a reversing camera. The “S&S” trim level indicated the inclusion of the Start & Stop system, which was a key feature for reducing fuel consumption.
Chassis & Braking
The Fullback Double Cab featured a robust chassis designed to withstand the demands of pickup truck use. The front suspension utilized independent coil springs, providing a comfortable ride on paved roads. The rear suspension employed leaf springs, which were better suited for carrying heavy loads. The braking system consisted of ventilated discs on the front wheels and drum brakes on the rear. While adequate for most 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 reasonably precise steering feel.
Market Reception & Comparison
The Fiat Fullback was generally well-received as a capable and affordable pickup truck. Critics praised its robust construction, off-road capabilities, and fuel efficiency. However, some reviewers noted that the interior design was somewhat basic and lacked the refinement of some competitors. Compared to other one-tonne pickups available in Europe and other markets, the Fullback offered a competitive price point. The 2.4-liter engine with the manual transmission provided a good balance between performance and economy, making it a popular choice for buyers who didn’t require the extra power of larger engines. The fuel economy of 6.4 l/100 km was respectable for a vehicle of this size and type.
Legacy
The Fiat Fullback’s production run was relatively short, lasting only two years. However, the 2.4-liter 4N15 engine has proven to be a reliable and durable unit in other Mitsubishi vehicles. The Fullback, being based on the Triton, benefits from the established parts availability and repair knowledge associated with the Mitsubishi platform. On the used car market, the Fullback Double Cab 2.4 4WD S&S represents a relatively affordable and practical option for buyers seeking a capable pickup truck. Its simplicity and robust construction make it a potentially long-lasting vehicle, provided it has been well-maintained. The combination of 4WD, a decent payload capacity, and reasonable fuel economy continues to make it an attractive option for those needing a versatile workhorse.
