Isuzu N-Series 2022 review: NLR Servicepack

Our test vehicle, to use its full model name, is the NLR 45-150 SWB AMT Servicepack X. It’s the most compact model in the N-Series range and as a result is similar (and in some cases much smaller) in key dimensions to a one-tonne ute. It only comes in one specification with 3.0-litre turbo-diesel, six-speed automated manual transmission (we’ll get to that) and dual-rear wheels, for a list price of $87,789.

In addition to its service body, this hard-worker comes standard with half a dozen 16-inch steel wheels, 195/75R16C Michelin tyres and a full-size spare. The single cab is well-equipped with useful features like keyless entry with central locking of cab and service body, big door mirrors with power adjustment, heating and lower wide-angle view, driver’s bucket seat with mechanical suspension and weight adjustment up to 130kg, two-way adjustable steering column, cruise control and bright LED interior lighting. Also standard is a 4000kg-rated tow-bar, reversing camera, loud reversing alarm and door-mounted cornering lamps.

There’s also an infotainment system with smallish 6.2-inch control screen and DAB+ radio. Even though there’s no Apple CarPlay or Android Auto, it has multiple connectivity including internet radio via smartphone, external camera inputs, navigation, reversing sensors and tyre pressure monitoring. The driver also gets a multi-information display and there’s plenty of the latest safety tech headlined by AEB.

Isuzu’s 4JJ1-TCS 3.0-litre four-cylinder turbo-diesel is closely related to the 4JJ3-TCX in the current D-Max ute and MU-X wagon. Tuned for hard work and long life, it produces 110kW at 2800rpm and 375Nm across a 1200rpm-wide torque band between 1600-2800rpm. It’s also equipped with a vacuum-controlled exhaust brake which can be switched on or off.

Isuzu’s MYY-6E is a six-speed fully-automated manual transmission, which may sound like a contradiction in terms, However, like the engine, it's designed for a long service life under continuous heavy loads. It uses an electro/hydraulically controlled wet clutch and lock-up torque converter to provide either fully automatic or clutch-less manual shifting. There’s also slow/fast gear engagement control, first gear start (for heavy loads) and normal or economy drive modes.

A handy power take-off (PTO) facility can drive numerous on-site implements, with drive coming from a counter gear on the left-hand side of the transmission case.

The doors open 90 degrees for easy access and there are decent boot-sized steps plus big handles on the windscreen pillars to help you climb aboard.

It’s a different driving position to a ute, as you sit high above the engine with your feet ahead of the front wheels and hands on a bus-style flat steering wheel. There’s also a big left footrest with lots of open floor around it, so there’s ample space to rest your foot given there’s no clutch pedal.

The suspension seat can be easily adjusted to suit a driver’s weight and works well in providing a more comfortable ride. The seat’s base cushion has no rake adjustment but there is some movement available in the backrest. Large glass areas deliver a commanding view ahead and to the sides while the big door mirrors provide excellent coverage of what’s behind. 

Its harsh ride quality when unladen is to be expected as it’s designed to carry permanent payloads between 1.0 and 1.5 tonnes. You do get thrown around, particularly on poor road surfaces with large bumps and dips. However, it’s no worse than the rodeo ride we’ve experienced in some unladen single-cab chassis utes which don’t have the luxury of a suspension seat.

The cab’s insulation ensures low engine and tyre noise, particularly during highway use where the turbo-diesel requires 2200rpm to maintain 100km/h and 2500rpm at 110km/h. The most noticeable noise at these speeds comes from wind buffeting around the mirrors, roof racks etc but it’s far from intolerable, as conversations can still take place at normal volumes.

Braking (particularly when using the exhaust brake) and steering response are good but the automated manual transmission takes some getting used to, as it shifts gears at about the same leisurely speed you would do manually.

These long pauses between cogs can be frustrating when climbing hills, as you naturally want to downshift quicker to avoid losing momentum, but you can’t do it in either automated or manual modes. Isuzu claims that the duration of these automated shifts can be shortened, but after consulting the owner’s manual to make this adjustment, we didn’t notice much if any difference (or perhaps we just didn’t do it correctly).

The engine has good flexibility and does not respond well to aggressive treatment. A more relaxed approach is best, using low rpm to optimise torque.

There’s no ANCAP rating required for vehicles in this weight class. Even so, it does have numerous passive and active safety features including driver and passenger airbags plus advanced driver assistance systems (ADAS) including AEB, forward collision warning, distance warning, lane departure warning, traffic movement warning, cab-tilt warning and more. There’s also a reversing camera, reversing alarm (the loud beep-beep type) and door-mounted cornering lamps.
