The Fiat Fullback Double Cab LX 2.4d (181 Hp) AWD Automatic, 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 Mitsubishi Triton, tailored for markets outside of Australia and New Zealand where the Triton was already well-established. This variant, the LX 2.4d with the automatic transmission and all-wheel drive, was positioned as a mid-range offering, balancing capability with relative comfort and convenience. It aimed to appeal to buyers needing a versatile vehicle for both work and leisure, offering a practical alternative to more established competitors like the Toyota Hilux and Ford Ranger.

Powertrain & Engine Architecture
The Fullback LX 2.4d utilizes Mitsubishi’s 4N15 2.4-liter inline-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 relatively robust construction and decent fuel economy. The engine produces 181 horsepower at 3500 rpm and a substantial 430 Nm (317 lb-ft) of torque at 2500 rpm. The automatic transmission is a conventional five-speed unit, chosen for its simplicity and durability rather than outright performance. While not the most modern transmission available, it was considered adequate for the intended use case of the vehicle. The engine meets Euro 6 emission standards, incorporating a diesel particulate filter (DPF) to reduce harmful emissions.
Driving Characteristics
The 181 hp and 430 Nm of torque provide adequate, though not exhilarating, performance. The automatic transmission, while smooth in normal driving, can feel somewhat sluggish when attempting quicker acceleration or overtaking maneuvers. The gear ratios are tuned for practicality and fuel economy, prioritizing low-end torque for hauling and towing rather than high-speed performance. Compared to the manual transmission versions, the automatic sacrifices some responsiveness. The all-wheel-drive system offers improved traction on slippery surfaces, making it suitable for both on-road and light off-road use. The Fullback’s ride quality is generally comfortable, though the rear suspension can feel somewhat bouncy when unladen.
Equipment & Trim Levels
The LX trim level of the Fullback Double Cab offered a reasonable level of standard equipment. Typically included were features such as air conditioning, power windows and locks, a basic audio system with USB connectivity, and alloy wheels. Interior upholstery was generally cloth, with a functional, rather than luxurious, design. Optional extras available for the LX trim could include a touchscreen infotainment system with navigation, a reversing camera, and upgraded audio speakers. Safety features included ABS brakes, driver and passenger airbags, and stability control.
Chassis & Braking
The Fullback Double Cab utilizes a body-on-frame construction, providing a robust and durable platform for carrying heavy loads. The front suspension consists of double wishbones, while the rear suspension employs a torsion bar setup. This configuration balances ride comfort with load-carrying capacity. Braking duties are handled by ventilated discs at the front and drum brakes at the rear. The braking system is assisted by ABS (Anti-lock Braking System) to enhance safety during emergency stops. The steering is rack and pinion with electric power assistance, providing a reasonably light and responsive feel.
Market Reception & Comparison
The Fiat Fullback received mixed reviews upon its launch. Critics generally praised its practicality, robust construction, and competitive pricing. However, it was often criticized for its somewhat dated interior, unrefined engine, and the less-than-inspiring performance of the automatic transmission. Compared to rivals like the Toyota Hilux and Ford Ranger, the Fullback offered a more affordable entry point but lacked the refinement and advanced features of those competitors. Fuel economy was generally considered acceptable, but not class-leading. Reliability reports have been generally positive, benefiting from the proven mechanicals of the Mitsubishi Triton.
Legacy
The Fiat Fullback, while not a massive sales success in most markets, established Fiat as a player in the competitive pickup truck segment. The 4N15 engine, in this configuration, has proven to be a relatively reliable unit, with many examples still in service today. On the used car market, the Fullback Double Cab LX 2.4d Automatic represents a practical and affordable option for buyers seeking a capable and versatile pickup truck. Maintenance costs are generally reasonable, and parts availability is good, thanks to the shared components with the Mitsubishi Triton. However, potential buyers should be aware of the potential for DPF issues, common to modern diesel engines, and ensure regular maintenance is performed.
