The characteristics of 2015 Isuzu NQR trucks help you increase productivity while lowering your overall ownership costs. Power, efficiency, and extended life are all hallmarks of these engines. The frames may accommodate various body types. The excellent vision and agility provided by this vehicle’s low cab front design are unmatched. If you run a small company with just one truck or manage a large fleet, you need vehicles that can accomplish more while operating less.

Performance and Fuel Economy

This engine, famed for its power and toughness across the globe, has been enhanced to give even greater performance and efficiency on the NPR-HD and NQR models and the NRR. Using its high-pressure common-rail fuel injection system and intercooler, variable-geometry turbocharger, it extracts the maximum energy from every fuel drop. Its 150 horsepower and 282 lb-ft of torque result from these elements working together.

4HK1-TC vehicles equipped with automatic transmissions now have 210 horsepower and 190 horsepower, respectively, while manual-transmission trucks have 190 horsepower and 210 horsepower, respectively, thanks to a water-cooled EGR system. At Isuzu, we never sacrifice performance for dependability, longevity, or fuel efficiency to pursue more horsepower.

Isuzu Family

With the NLR (4500/5500kg GVM) and NNR (4500kg GVM) families, as well as the wider-cab NPR (4500-7500kg GVM) and NQR (8000/8700kg GVM) models, as well as the all-wheel-drive NLS and four-wheel-drive NPS, as well as the NLR/NPR CNG versions, the N Series offers 46 different model variations. Various wheelbases, crew cab, tipper types, and Traypack/Tradepack packages with trays and several factory extras are available, as are a variety of ready-to-work configurations.


The 3.0-liter 4JJ1 and 5.2-liter 4HK1 turbo-diesel engines power the range, paired to either a six-speed manual or six-speed automatic manual gearbox. 114 kW (153 horsepower) at 2600 rpm and 419 Nm from 1600-2600 rpm, or 140 kW (188 hp) at 2600 rpm and 513 Nm from 1600-2600 rpm, are available in the 3.0-liter engine for the NLR and NNR families, while the 5.2-liter engine is available for the NPR and NQR families.

When it comes to oil changes, Isuzu diesel engines may go for up to 10,000 miles between ones. For most Isuzu diesel trucks, the B-10 engine life is 310,000 miles, which means that 90% of our engines will still be running properly. NPR-HD, NQR, and NRR come standard with the 4HK1-TC 215 horsepower turbocharged inter-cooled diesel engine, which has electronic high-pressure common-rail direct injection and a water-cooled exhaust gas recirculation system.
