2020-2023 Isuzu D-Max III Space Cab 3.0d (190 Hp) Automatic

The Isuzu D-Max III Space Cab 3.0d (190 Hp) Automatic, produced from 2020 to 2023, represents a significant iteration of Isuzu’s popular pickup truck. This variant, part of the third generation D-Max (introduced in late 2019), was primarily aimed at markets outside of North America, particularly Australia, Europe, and Asia. The Space Cab configuration offered a compromise between the single-cab workhorse and the full four-door crew cab, providing limited rear seating and a longer cargo bed. This specific 3.0-liter turbocharged diesel engine paired with a six-speed automatic transmission positioned itself as a mid-range offering, balancing performance with fuel efficiency and ease of use.

Technical Specifications

Powertrain & Engine Architecture

The heart of the D-Max Space Cab 3.0d is the Isuzu 4JJ3-TCX engine, a 3.0-liter inline-four cylinder diesel. This engine is a direct descendant of Isuzu’s long-standing diesel expertise, known for its robustness and reliability. The ‘TCX’ designation indicates a turbocharged and intercooled version, boosting power output to 190 horsepower at 3600 rpm and a substantial 450 Nm (331.9 lb-ft) of torque between 1600 and 2600 rpm. The engine utilizes a common rail direct injection system, delivering fuel at extremely high pressure for optimized combustion and reduced emissions. A double overhead camshaft (DOHC) valvetrain with four valves per cylinder further enhances breathing and efficiency. The six-speed automatic transmission, sourced from Aisin, was chosen for its durability and smooth shifting characteristics. This transmission is known for its ability to handle the engine’s torque output effectively, providing adequate performance for both on-road driving and hauling/towing applications.

Driving Characteristics

The 190 hp and 450 Nm of torque provide adequate, though not exhilarating, performance. The automatic transmission, while smooth, isn’t particularly quick to downshift, meaning overtaking maneuvers require planning. Compared to the manual transmission versions of the same engine, the automatic sacrifices some responsiveness. The gear ratios are tuned for fuel efficiency and towing capacity rather than outright acceleration. The D-Max’s rear-wheel-drive configuration contributes to a more traditional truck-like feel, with a focus on stability when carrying loads. The suspension, tuned for work and durability, provides a comfortable ride when unladen but can become somewhat bouncy when the cargo bed is heavily loaded.

Equipment & Trim Levels

The Space Cab 3.0d Automatic typically came with a reasonable level of standard equipment. This included air conditioning, power windows and locks, a basic audio system with Bluetooth connectivity, and steel wheels. Higher trim levels, often denoted by specific package names depending on the market, added features such as alloy wheels, a touchscreen infotainment system, reversing cameras, and upgraded interior trim. Interior upholstery was generally durable cloth, with options for leather available on higher-spec models. Safety features included ABS brakes, electronic stability control, and a driver’s airbag, with additional airbags available on some trims.

Chassis & Braking

The D-Max III utilizes a robust ladder-frame chassis, providing a solid foundation for its work-oriented design. The front suspension employs a double wishbone setup, while the rear utilizes a traditional leaf spring arrangement. This combination offers a good balance of load-carrying capacity and ride comfort. Braking duties are handled by ventilated discs at the front and drum brakes at the rear. While adequate for most applications, the rear drum brakes are a cost-saving measure compared to the all-disc setups found on some competitors. Electric power steering provides a light and easy steering feel, particularly useful for maneuvering in tight spaces.

Market Reception & Comparison

The Isuzu D-Max Space Cab 3.0d Automatic was generally well-received as a practical and reliable workhorse. Critics praised its fuel efficiency, robust build quality, and comfortable ride. However, some noted that the automatic transmission could feel sluggish at times, and the interior lacked the refinement of some competitors. Compared to other trims in the D-Max lineup, the 3.0d Automatic offered a good balance between performance and economy. The lower-powered 2.5-liter diesel was more affordable but lacked the pulling power of the 3.0-liter, while the higher-output versions (where available) came at a premium price. Against competitors like the Toyota Hilux, Nissan Navara, and Ford Ranger, the D-Max offered a compelling value proposition, particularly for buyers prioritizing durability and reliability.

Legacy

The Isuzu 4JJ3-TCX engine, in its various iterations, has proven to be exceptionally durable and reliable. The six-speed Aisin automatic transmission is also known for its longevity. In the used car market, the D-Max Space Cab 3.0d Automatic holds its value reasonably well, particularly examples that have been well-maintained. Common issues are relatively minor, often related to wear and tear on suspension components or routine maintenance items. The engine is known to be capable of high mileage with proper servicing, making it a popular choice for buyers seeking a dependable and long-lasting pickup truck.
