The Isuzu D-Max dual cab-chassis with a 1.9-litre turbo-diesel engine has a higher payload rating than its 3.0-litre equivalent, despite having less power and torque. This seems counterintuitive, but it all comes down to tare weights. The 1.9-litre version is 80kg lighter than the 3.0-litre version, which means it can legally carry 80kg more. Both models have the same 3000kg GVM rating.
In practical terms, this means that the 1.9-litre D-Max can handle a payload of 1084kg (after deducting the weight of additional equipment) compared to 1004kg for the 3.0-litre version.
To test this advantage, the vehicle was loaded with more than one tonne of payload and taken on the road. The smaller engine performed well under heavy loads, with the rear suspension and chassis handling the weight comfortably. The 1.9-litre turbo-diesel efficiently moved the load, especially during standing starts and highway driving.
Fuel consumption remained low, with the average consumption dropping to 10.7L/100km during highway driving with a loaded tray. The engine’s lighter weight, broad torque range, and shorter gearing contributed to its performance.
The Isuzu D-Max proved to be a capable workhorse, offering a practical and economical option for tradies, farmers, and road crews.
Key Points:
- The 1.9-litre D-Max has a higher payload rating than the 3.0-litre version.
- Tare weights determine the payload capacity of the vehicles.
- The 1.9-litre D-Max is 80kg lighter than the 3.0-litre version.
- The 1.9-litre engine efficiently handles heavy loads with its broad torque range.
- Fuel consumption remains low even with a loaded tray.
Conclusion:
The Isuzu D-Max 1.9-litre turbo-diesel is a capable and economical option for those needing a vehicle with a high payload capacity. Its lighter weight and efficient performance make it a practical choice for various applications.
