The Fiat Fullback Double Cab SX 2.4d, produced from 2017 onwards, represents Fiat’s entry into the one-tonne pickup truck segment. Developed in collaboration with Mitsubishi Motors, the Fullback shares its platform with the Triton (known as the L200 in many markets). This model aimed to provide Fiat with a presence in a market dominated by established players like Toyota, Ford, and Nissan, particularly in regions where pickup trucks are favored for both commercial and personal use. The SX 2.4d trim, equipped with a 2.4-liter diesel engine producing 154 horsepower, served as a mid-range offering within the Fullback lineup, balancing capability with affordability. It was primarily marketed towards customers needing a versatile vehicle for work and leisure, offering a practical alternative to larger, more expensive trucks.

Introduction
The Fiat Fullback Double Cab SX 2.4d, launched in 2017, is a mid-size pickup truck designed to cater to a broad range of users. Built upon the Mitsubishi Triton platform (internally designated as the fifth generation), the Fullback represents Fiat’s re-entry into the pickup market after a period of absence. The “Double Cab” configuration offers seating for five passengers, making it suitable for both work and family use. The SX 2.4d trim level positions itself as a practical and well-equipped option, offering a balance between performance, features, and price. It was intended to appeal to customers who needed a robust and versatile vehicle without the expense of higher-spec models.
Powertrain & Engine Architecture
The heart of the Fullback SX 2.4d is the 4N15 2.4-liter inline-four cylinder diesel engine. This engine, developed by Mitsubishi, is a robust and relatively simple design known for its durability. It utilizes a common rail direct injection system, delivering fuel at high pressure for efficient combustion and reduced emissions. A turbocharger with an intercooler further enhances performance, providing increased power and torque. The engine produces 154 horsepower at 3500 rpm and a substantial 380 Nm (280 lb-ft) of torque between 1500 and 2500 rpm, making it well-suited for hauling and towing. The SX 2.4d is equipped with a six-speed manual transmission, chosen for its durability and driver control. The engine is longitudinally mounted, driving the rear wheels as standard.
Driving Characteristics
The 154 hp 2.4d engine, paired with the six-speed manual transmission, provides adequate performance for everyday driving and typical pickup truck tasks. While not exceptionally quick, the engine delivers strong low-end torque, making it capable of handling loads and navigating challenging terrain. The gear ratios are well-chosen for both on-road cruising and off-road crawling. Compared to higher-output versions of the Fullback (which were not widely available in all markets), the SX 2.4d offers a more economical driving experience. The manual transmission allows for greater driver control, particularly when towing or navigating difficult conditions. However, it lacks the convenience of an automatic transmission, which was offered on some Fullback variants. The leaf spring rear suspension, while contributing to load-carrying capacity, can result in a somewhat firm ride when unladen.
Equipment & Trim Levels
The SX trim level of the Fullback Double Cab offers a reasonable level of standard equipment. Interior features typically include air conditioning, a basic audio system with USB connectivity, power windows, and central locking. The interior upholstery is typically durable cloth. Safety features include ABS brakes, electronic brakeforce distribution (EBD), and driver and passenger airbags. Optional extras available on the SX trim could include alloy wheels, a rear-view camera, and upgraded audio systems. The dashboard layout is functional and straightforward, prioritizing practicality over luxury. The SX trim aimed to provide essential features without the added cost of more premium options.
Chassis & Braking
The Fullback Double Cab utilizes a robust ladder-frame chassis, providing a solid foundation for its load-carrying capabilities. The front suspension consists of double wishbones, offering a degree of ride comfort and handling precision. The rear suspension employs leaf springs, a traditional design favored for its durability and ability to handle heavy loads. The braking system features ventilated discs on the front wheels and drum brakes on the rear. ABS (Anti-lock Braking System) is standard, enhancing safety during emergency braking situations. The steering is rack and pinion with electric power assistance, providing a responsive and relatively light steering feel.
Market Reception & Comparison
The Fiat Fullback received mixed reviews upon its launch. Critics generally praised its robust construction, capable engine, and competitive pricing. However, some noted that the interior felt somewhat dated compared to newer pickup trucks on the market. Compared to other trims in the Fullback lineup, the SX 2.4d offered a compelling value proposition for buyers prioritizing practicality and affordability. It provided a good balance between performance and fuel economy, making it a suitable choice for both work and leisure. Fuel economy figures of around 6.7 l/100km (35.1 US mpg) were competitive within the segment. Reliability reports have generally been positive, with the Mitsubishi-sourced engine proving to be durable and dependable.
Legacy
The Fiat Fullback, while not a massive sales success for Fiat, established a foothold for the brand in the competitive pickup truck market. The 2.4-liter diesel engine, sourced from Mitsubishi, has proven to be a reliable and long-lasting powertrain. On the used car market, the Fullback Double Cab SX 2.4d represents a relatively affordable and practical option for buyers seeking a capable pickup truck. Its robust construction and durable engine make it a potentially good long-term investment, provided it has been well-maintained. The Fullback’s legacy lies in offering a viable alternative to established pickup truck brands, providing a blend of capability, affordability, and Italian styling.
