2016-2017 Fiat Fullback Double Cab 2.4 (154 Hp) S&S

The Fiat Fullback Double Cab 2.4 (154 Hp) 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 154 horsepower and the “S&S” (Start & Stop) system represented a mid-range offering within the Fullback lineup, positioned between lower-powered base models and higher-output variants.

Technical Specifications

Powertrain & Engine Architecture

The Fiat Fullback 2.4 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 enhance 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 “S&S” designation indicates the inclusion of a Start & Stop system, which 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 in the chassis, and power is delivered to the rear wheels via a six-speed manual transmission. The engine’s valvetrain features a double overhead camshaft (DOHC) configuration with four valves per cylinder, optimizing breathing and contributing to its power output.

Driving Characteristics

The 154 hp 2.4-liter engine, paired with the six-speed manual transmission, provided adequate performance for typical pickup truck duties. While not exceptionally quick, it offered sufficient power for hauling moderate loads and navigating various terrains. The manual transmission allowed for greater driver control, particularly when towing or driving off-road. Compared to higher-output versions of the Fullback, this variant prioritized fuel economy and affordability over outright performance. The gear ratios were tuned to balance acceleration and fuel efficiency, with a relatively tall sixth gear for highway cruising. The rear-wheel-drive configuration provided a traditional pickup truck feel, but it could be less capable in slippery conditions compared to four-wheel-drive models. The leaf spring rear suspension, while robust, resulted in a firmer ride quality, especially when unladen.

Equipment & Trim Levels

The Fullback Double Cab 2.4 S&S typically came equipped with features such as air conditioning, power windows, central locking, and an audio system with USB connectivity. Safety features included ABS brakes, driver and passenger airbags, and seatbelt pretensioners. Interior upholstery was generally cloth, with a functional and durable design. Optional extras could include alloy wheels, a navigation system, and a reversing camera. The trim level often dictated the availability of features like leather upholstery, heated seats, and more advanced infotainment systems. The S&S variant often represented a mid-range trim, offering a good balance of features and value.

Chassis & Braking

The Fullback Double Cab featured a body-on-frame construction, providing a robust and durable platform for hauling and towing. The front suspension utilized independent coil springs, offering a degree of ride comfort and handling precision. The rear suspension employed leaf springs, chosen for their load-carrying capacity and durability. Braking duties were handled by ventilated discs at the front and drum brakes at the rear. The ABS system helped to maintain steering control during emergency braking situations. The chassis was designed to withstand the stresses of off-road driving and heavy loads. Stabilizer bars were included to reduce body roll during cornering.

Market Reception & Comparison

The Fiat Fullback was generally well-received as a capable and affordable pickup truck. Critics praised its robust construction, comfortable cabin, and competitive pricing. However, some reviewers noted that its styling was somewhat conservative and that its ride quality could be improved. Compared to other one-tonne pickups in the European market, such as the Ford Ranger and the Toyota Hilux, the Fullback offered a compelling value proposition. The 2.4-liter engine provided reasonable fuel economy, but it wasn’t as refined or powerful as some of the more modern engines offered by competitors. The manual transmission was appreciated by drivers who preferred greater control, but it wasn’t as convenient as the automatic transmissions offered on some rival models.

Legacy

The Fiat Fullback’s production run was relatively short, ending in 2017. However, it established Fiat as a player in the one-tonne pickup segment. The 4N15 engine, in particular, has proven to be a reliable and durable unit, and examples continue to be found in good working order on the used car market. The Fullback’s simplicity and robust construction make it a relatively easy vehicle to maintain. While it may not offer the same level of refinement or technology as more modern pickups, it remains a practical and affordable option for those seeking a capable workhorse. Its association with the Mitsubishi Triton also means that parts availability is generally good.
