Engine Displacement: 2,999 cc (3.0L) / 1,898 cc (1.9L)
The D-Max is powered by the evolution of Isuzu’s commercial-grade diesel engines. The flagship 3.0L 4JJ3-TCX engine is engineered for high-torque applications and longevity, while the 1.9L RZ4E-TC "Blue Power" engine focuses on thermal efficiency and reduced emissions. For 2026, Isuzu has also introduced a 2.2L turbo-diesel variant in specific markets to bridge the gap between efficiency and power.
Max Power: 190 PS (140 kW) @ 3,600 rpm
The 3.0L engine produces a robust 190 PS, providing ample power for highway overtaking even when fully laden. The 1.9L variant delivers 150 PS, while the new 2.2L engine generates 163 PS (120 kW). The power delivery is specifically tuned to be accessible at lower RPMs, which is critical for a utility vehicle.
Max Torque: 450 Nm @ 1,600–2,600 rpm
Torque is the defining metric for the D-Max. The 3.0L engine offers a flat torque curve of 450 Nm, ensuring maximum pulling power from a standstill. The 1.9L variant offers 350 Nm, and the 2.2L version steps up to 400 Nm. This high torque-to-weight ratio allows the D-Max to maintain its 3,500 kg towing capacity across most configurations.
No. of Cylinders: 4
The D-Max range utilizes an Inline 4-cylinder layout. Isuzu prioritizes heavy-duty internals over cylinder count, featuring induction-hardened cylinder bores and a steel timing chain to ensure the engine lasts well beyond the typical vehicle lifecycle.
Valve Train: DOHC (16 Valves)
Both engines feature a Double Overhead Camshaft (DOHC) arrangement with 4 valves per cylinder. This design optimizes the air-fuel mixture and exhaust expulsion, which is essential for meeting modern Euro 6d / BS6 emission standards without sacrificing mechanical simplicity.
Fuel System: Electronic Common Rail Direct Injection
The high-pressure common rail system works in tandem with a Variable Geometry System (VGS) Turbocharger. This setup ensures precise fuel atomization, reducing "diesel knock" and providing immediate throttle response across the rev range.
0-100 km/h Time: 10.2 seconds
The D-Max 3.0L 4x4 variant achieves a 0-100 km/h time of approximately 10.2 seconds. While speed is not the primary objective for a pickup, this performance ensures the vehicle does not feel sluggish when merging into fast-moving traffic.
Top Speed: 180 km/h
The D-Max is capable of reaching a top speed of 180 km/h, though it is geared for low-end torque rather than top-end velocity. Stability at highway speeds is aided by the vehicle's long wheelbase and updated aerodynamic profiling.
