Powertrain & Engine Architecture
The heart of this D-Max variant is the RZ4E-TC 1.9-liter inline-four cylinder diesel engine. This engine represented a move towards downsizing and improved efficiency compared to the previous 2.5-liter engine offered in earlier D-Max models. The RZ4E-TC utilizes a cast iron block and aluminum cylinder head, a common configuration for durability and weight reduction. It features a single turbocharger with an intercooler to enhance power and torque output. The fuel injection system is a common rail direct injection system, allowing for precise fuel delivery and optimized combustion. The engine produces 164 horsepower at 3600 rpm and 360 Nm (265.52 lb-ft) of torque between 2000 and 2500 rpm. The six-speed manual transmission was the standard offering for this configuration, providing a good balance between fuel economy and driver control. While an automatic transmission was available in some markets, it wasn’t as commonly paired with this specific engine.
Driving Characteristics
The 1.9-liter engine, paired with the six-speed manual transmission, provided a reasonably responsive driving experience. While not exceptionally quick – 0-60 mph took around 12.1 seconds – it offered sufficient power for everyday driving and hauling moderate loads. The torque curve was relatively flat, providing good pulling power from low engine speeds, which was particularly useful for off-road driving and towing. Compared to the more powerful 2.5-liter engine, the 1.9-liter felt less strained at higher speeds, but also lacked the outright acceleration of its larger counterpart. The manual transmission offered precise shifts, and the gear ratios were well-suited to both on-road and off-road conditions. The overall driving experience was characterized by practicality and dependability rather than sporty performance.
Equipment & Trim Levels
The 1.9-liter D-Max typically came equipped with a respectable level of standard features. These generally included air conditioning, power windows, central locking, and a basic audio system with USB connectivity. Higher trim levels added features such as alloy wheels, a touchscreen infotainment system, rear parking sensors, and a reversing camera. Interior upholstery was typically cloth, with durable plastic trim throughout the cabin. Optional extras included a navigation system, leather upholstery, and a more advanced audio system. Safety features such as ABS brakes and multiple airbags were standard across the range.
Chassis & Braking
The D-Max II utilized a body-on-frame construction, providing a robust and durable platform for demanding applications. The suspension consisted of independent double wishbones at the front and leaf springs at the rear. This setup provided a comfortable ride quality, even when carrying a load. The braking system featured ventilated discs at the front and drum brakes at the rear. ABS (Anti-lock Braking System) was standard, enhancing safety during emergency braking situations. The chassis was designed to handle a substantial payload, with a maximum load capacity of around 1096 kg (2416.27 lbs).
Market Reception & Comparison
The 1.9-liter D-Max was generally well-received by critics as a practical and fuel-efficient workhorse. It offered a good balance between performance, economy, and reliability. Compared to other mid-size pickups in its class, such as the Toyota Hilux and Ford Ranger, the D-Max often stood out for its value for money and robust build quality. However, some reviewers noted that the 1.9-liter engine lacked the refinement and power of some of its competitors. Fuel economy was a strong point, with combined fuel consumption figures around 7 l/100 km (33.6 US mpg). Reliability was also a key strength, with the Isuzu diesel engine having a reputation for longevity.
Legacy
The RZ4E-TC 1.9-liter engine has proven to be a relatively reliable powertrain. While some early models experienced minor issues with the diesel particulate filter (DPF), these were generally addressed through software updates. On the used car market, the 1.9-liter D-Max represents a good value proposition for buyers seeking a dependable and affordable pickup truck. Its fuel efficiency and robust construction make it a practical choice for both work and leisure. The availability of spare parts is generally good, and maintenance costs are relatively reasonable. The D-Max II, particularly the 1.9-liter variant, has cemented Isuzu’s reputation as a manufacturer of tough and reliable pickup trucks.
