INTRODUCTION
The Isuzu D-Max III Space Cab 1.9d (163 Hp) 4WD Automatic, launched in 2020, is part of the third generation of Isuzu’s popular pickup truck. This generation, designated as the 2020-2023 model, represented a significant overhaul of the D-Max line, focusing on improved safety, comfort, and efficiency. The Space Cab body style offers a compromise between the single cab’s practicality and the double cab’s passenger capacity, featuring smaller rear doors and seating for four. The 1.9-liter engine and automatic transmission combination was positioned as a versatile option, appealing to buyers who needed a capable workhorse but also desired the convenience of an automatic gearbox. The D-Max is a mainstay in many global markets, particularly in Australia, Thailand, and Europe, where pickup trucks are widely used for both commercial and personal purposes.
Powertrain & Engine Architecture
At the heart of the D-Max III Space Cab 1.9d is the RZ4E-TC, a 1.9-liter inline-four cylinder diesel engine. This engine is a key component of Isuzu’s efforts to balance power and fuel economy. It utilizes a high-pressure common rail direct injection system, delivering fuel directly into the combustion chamber for improved efficiency and reduced emissions. The engine also features a variable geometry turbocharger (VGT) and an intercooler, which enhance power output by increasing the density of the intake air. The engine produces 163 horsepower at 3600 rpm and 360 Nm (265.52 lb.-ft.) of torque between 2000 and 2500 rpm. The six-speed automatic transmission, sourced from Aisin, is designed to provide smooth and efficient gear changes. It features a torque converter and electronically controlled shifting, optimizing performance and fuel consumption. The transmission is geared towards providing adequate pulling power at lower speeds, essential for towing and hauling, while still allowing for comfortable highway cruising.
Driving Characteristics
The 1.9-liter engine paired with the six-speed automatic transmission delivers a driving experience that prioritizes usability and efficiency over outright performance. Acceleration is adequate for everyday driving, but it won’t provide the briskness of higher-powered D-Max variants. The automatic transmission generally shifts smoothly, although it can sometimes feel hesitant during quick acceleration or when navigating hilly terrain. The 4WD system provides enhanced traction in off-road conditions and on slippery surfaces. The gear ratios are tuned to maximize fuel economy, which translates to a more relaxed driving experience on the highway. Compared to the manual transmission versions of the same engine, the automatic offers greater convenience, particularly in urban environments. However, it does result in a slight reduction in fuel economy and a less direct connection to the engine.
Equipment & Trim Levels
The D-Max III Space Cab 1.9d (163 Hp) 4WD Automatic typically came equipped with a range of standard features. These included air conditioning, power windows, central locking, and a basic audio system with Bluetooth connectivity. Safety features such as ABS, electronic stability control, and multiple airbags were also standard. Higher trim levels offered additional features such as alloy wheels, a touchscreen infotainment system with navigation, a reversing camera, and parking sensors. Interior upholstery was typically cloth, with options for leather seats on higher-spec models. The dashboard layout was functional and straightforward, prioritizing ease of use over stylistic flair.
Chassis & Braking
The D-Max III Space Cab utilizes a robust ladder-frame chassis, providing a solid foundation for its pickup truck capabilities. The front suspension consists of double wishbones, while the rear suspension employs leaf springs. This configuration is designed to handle heavy loads and provide a comfortable ride, although it can sometimes feel slightly firm when unladen. The braking system features ventilated discs on the front wheels and drum brakes on the rear. ABS (Anti-lock Braking System) is standard, enhancing braking performance and stability. The steering is rack and pinion with electric power assistance, providing a responsive and precise steering feel.
Market Reception & Comparison
The Isuzu D-Max III Space Cab 1.9d (163 Hp) 4WD Automatic was generally well-received by critics as a practical and reliable workhorse. It was praised for its fuel efficiency, comfortable ride, and robust build quality. However, some reviewers noted that the 1.9-liter engine could feel underpowered when fully loaded or when towing heavy trailers. Compared to the higher-output 3.0-liter engine options, the 1.9d offered a more affordable entry point into the D-Max range, but at the expense of performance. In terms of fuel economy, the 1.9d generally outperformed the larger engine variants, making it a popular choice for buyers who prioritized efficiency. Reliability was a key strength of the D-Max, and the 1.9d engine proved to be a durable and dependable unit.
Legacy
The Isuzu D-Max III Space Cab 1.9d (163 Hp) 4WD Automatic has established a reputation as a reliable and capable pickup truck in the used car market. The RZ4E-TC engine, while not the most powerful in the D-Max lineup, has proven to be durable and relatively easy to maintain. The automatic transmission is also generally considered to be reliable, provided it is serviced regularly. These vehicles continue to be popular choices for buyers seeking a practical and affordable pickup truck for work or leisure. The combination of fuel efficiency, 4WD capability, and a comfortable interior makes it a versatile option for a wide range of applications.
