Isuzu NMR vs Mitsubishi Triton

What's the difference?

A truck like the NPR (or any other truck, really) is never going to replace a dual-cab ute in terms of its duality. While the latter can tend to weekday chores and be quickly reconfigured for weekend fun, the light truck has no such facility. Nope, it’s a workhorse. Period.

You need a fair bit of real estate just to park the Isuzu overnight and it certainly won’t fit in the typical supermarket car space. It’s hardly sporty to drive, either, although the latest upgrades have made it more user friendly in a total sense and safer than ever before.

But what it does do that a dual-cab ute can’t often do, is tackle bigger, heavier jobs with a fair bit of bandwidth still up its sleeve. And if the nine-to-five side of things is where you need to be, then a vehicle like this has to be worth a look. And if you consistently find that you’re sailing close to the wind in terms of exceeding a ute’s legal payload, towing capacity or GCM, then the extra bigness of a light truck could make a huge difference.

That’s especially so given the price tag. Okay, you’re not buying a lot of high tech for your money, but you are getting some seriously stout engineering and an expectation that you won’t be working the thing to death anytime soon.

Apart from its distracting driver attention monitor, we can't see any major flaws that would detract from this vehicle’s comfort, practicality and performance when serving as either a utilitarian 4x4 workhorse or back-to-basics 4x4 dual cab for adventures off the beaten track.

It can’t be easy to make a light truck look fashionable, but Isuzu has done a reasonable job of making the thing look, at least, current. The lighting has all been changed to LEDs now, and the bold, angular face the truck presents looks pretty modern.

But new tech has also forced some design changes. The bull-bar that is part of the Tradepack deal, for instance, has been redesigned with changes to the main hoop. That’s all to accommodate the radar units inside each headlight that inform the front cross-traffic warning system of anything in the way.

Also notable is the attention to detail of the optional (rather than the alloy tray seen here) Australian-made service body. With a choice of internal layouts, the flip-up sides reveal a proper workshop on wheels when configured that way.

It’s also nice to see that all the clips and catches on the drop-side tray can be easily replaced if damaged.

Our test vehicle rides on a compact 3130mm wheelbase and is 1865mm wide and 1795mm tall, which combined with a 12.4-metre turning circle makes it agile and easy to manoeuvre both on and off-road.

Speaking of which, its all-terrain credentials include 228mm of ground clearance, a useful 30.4 degrees approach angle (without bull-bar) and 23.4 degrees ramp breakover angle, with the departure angle dependent on the type of tray fitted. These numbers would be more than adequate for accessing rugged worksites.

Its front suspension is double-wishbone with coil-springs, paired with a robust leaf-spring live rear axle. Brakes are front discs and rear drums and it has electric power-assistance for the rack and pinion steering.

Looks are subjective of course but we reckon it has a robust and purposeful appearance in cab-chassis form, particularly with the accessories fitted to our example.

Chrome is all but extinct in its predominantly grey interior. However, hard surfaces on the centre console and door-pulls have a synthetic carbon-fibre finish, which adds a touch of style to a low-maintenance cabin that won’t get trashed by spilled coffee or muddy boots.

You also won’t find fancy features like digital instruments (it has analogue speedo/tacho) or an electronic handbrake (this one’s the good old manual lever). Plus there’s physical dials for audio volume/tuning and ‘piano key’ buttons for the cabin’s climate control, which ensures no distracting touchscreen prompts when driving.

The new cabin Isuzu has brewed up certainly brings the truck into the present, but it’s still very much a light truck in some respects. As in, it’s still a pretty good climb inside, although there are steps and handles to make that easier. The steering column still gets in the way as you swing your left leg inside, though.

The plastic surfaces would still make a car interior designer cringe, and the floor is vinyl and the seats cloth. But the three-abreast seating arrangement makes sense and, should you choose the dual-cab N Series option, there’s actually seven seats in all.

Cabin storage has obviously been a priority for Isuzu, and there are three large, netted overhead bins above the top of the windscreen, as well as bins and buckets across the width of the lower dashboard. Interestingly, each door has just a single, slim pocket and no bottle storage.

The centre console addresses that somewhat with a pair of cup-holders and a pen slot, while there’s also a large bin behind the seat on the bulkhead. There’s also an interior light that wouldn’t look out of place in an industrial kitchen.

The dashboard is home to a pair of USB charge-ports in the centre and the truck stuff continues with a wand for the exhaust brake and a knob near the steering column for a fast-idle setting. It’s also nice to see that even though Isuzu has adopted keyless entry and start for the N Series, the starter button resembles a conventional key and is located right where it should be in the side of the steering column.

What’s missing? Mainly a vanity mirror on either side of the cabin and a physical volume knob for the stereo. Oh, and paddle shifters would be nice too, especially when towing.

Externally, the Tradepack option gets you an aluminium drop-side tray, sturdy ladder racks, a tow bar, bull bar, toolboxes fitted below the tray between the axles and even a wash station for after-work clean ups.

The tray is fitted in Australia (many of the Ready to Work body options are also made here) and the load floor is a vast expanse of alloy with the ability to cope with small, heavy objects thanks to its high-impact materials. But the usual drop-side tray caveats apply including a high loading height, rattling from the sides and the legal requirement to lash everything down before hitting the road.

Meantime, part of the overall appeal of the Isuzu line-up is that there are something like 40 different permutations of cabin width, wheelbase, GVM, overall length and driveline.

But here’s perhaps the N Series’ greatest trick when it comes to being practical: While it’s easy to dismiss the vehicle for being too big and unwieldy, many operators would possibly find that the extra payload and real estate in the cargo area means that they might not need to tow a trailer every time they venture on to a job site. At which point, the dual-cab ute with a tandem trailer starts to look less convenient, especially if there’s any reversing or squeezing on to a tight site involved.

Oh, and if tight spaces really are an issue, the N Series’ sub-10m turning circle makes a typical dual-cab’s 12.5 metre turning circle look ridiculously ungainly. And that’s before we get to that trailer.

Typically for a vehicle like this, a full-sized spare tyre is included.

With a kerb weight of only 1993kg (without tray) and 3200kg GVM, our test vehicle has a 1207kg payload rating. However, after you add the combined weight of its steel tray and other accessories (417kg), the payload rating is reduced by the same amount to 790kg. Even so, that still leaves a sizeable weight capacity for up to five tradies and their tools.

It’s also rated to tow up to 3500kg of braked trailer but with its 6250kg GCM (or how much it can legally carry and tow at the same time) the payload would have to be reduced by 450kg (from 790kg to 340kg) to avoid exceeding the GCM.

In real-world use it’s unlikely that many (if any) Triton owners would need to tow 3500kg but it’s important to be across these numbers to avoid overloading, which is dangerous and illegal.

The genuine accessory galvanised steel tray is internally 1650mm long and 1780mm wide. It has a robust checker-plate floor and a tube-frame front bulkhead with sturdy wire-mesh rear window protection.

There’s also swing-up load retainers on top of the tube-frame on each side, which when paired with the matching rear tube-rack accessory provides secure carrying space for extension ladders or long lengths of timber and PVC pipe/conduit.

There’s also external rope/strap rails along each side but like all steel trays we’ve come across there’s no internal load-anchorage points.

The driver and front passenger have access to a bottle holder and storage bin in each front door plus an overhead glasses holder and a large open compartment above the glovebox. The centre console offers more open storage plus two bottle/cupholders in the centre and a usefully-sized box at the back with a lid that doubles as a driver’s elbow rest.

The rear bench seat is comfortable and surprisingly spacious for tall people, given I’m 186cm and when seated behind the driver’s seat when set in my position, I have about 40mm of kneeroom and 60mm of headroom.

There’s also adequate head clearance for those seated in the slightly higher centre position, but the floor’s prominent transmission tunnel requires one boot either side and knees together between the front seat backrests.

And like all dual-cab utes short of a full-size US pick-up, rear shoulder room is squeezy for three adults, which is tolerable for short trips but a maximum of two adults would be ideal for longer drives.

Rear seat storage includes a bottle-holder and bin in each door plus pockets on each front seat backrest. The centre seat’s backrest also folds forward to serve as an armrest with dual bottle/cup-holders.

The bench seat’s base cushion is fixed, so unlike numerous rivals it can’t swing up and be stored vertically if more internal carrying space is required.

The Triton’s cab-chassis list pricing (without tray) starts at $34,490 for the GLX single-cab 4x2 manual and finishes at $61,540 for the premium GSR dual-cab 4x4 auto.

Our GLX test vehicle comes standard with a 2.4-litre twin-turbo four-cylinder diesel engine (shared by all Tritons) and optional six-speed automatic for $49,490. This pricing is competitive with base-model 4x4 dual-cab-chassis equivalents like the Toyota HiLux Workmate ($48,735), Ford Ranger XL ($49,230) and Isuzu D-Max SX ($51,200).

However, our example is loaded with numerous items from Mitsubishi’s genuine accessories range including a steel tray ($5775), rear ladder rack ($951.42), steel bull-bar ($4755), driving lights ($1295), side-steps ($1750) and 3500kg towing kit/electronic brake controller ($2370).

This desirable ensemble adds almost $17,000 to the price, which with on-road costs would be nudging $70K to drive away. So, buyers must keep their budgets in mind, as it’s easy to get carried away in genuine accessory lolly shops.

Our test vehicle comes standard with 17-inch steel wheels and 265/65R17 all-terrain tyres plus a full-size spare. It also has heavy-duty rear suspension and underbody armour, front/rear parking sensors, reversing camera, tyre-pressure monitoring and more.

The work-focused cabin has wipe-clean fabric seat trim and vinyl floors, power-adjustable driver’s lumbar support, twin 12-volt accessory sockets and USB ports, 7.0-inch driver’s instrument cluster and a four-speaker audio system controlled by a 9.0-inch multimedia screen with Android Auto, Apple CarPlay and Bluetooth connectivity.

Believe it or not there’s actually a family connection between the 3.0-litre turbo diesel in the Isuzu NRL and the Isuzu D-Max dual-cab and MU-X SUV.

While the displacement of the D-Max remains, the unit in the light truck has been retuned to liberate more torque at lower engine speeds. In this case, that’s 129kW at 2860rpm and 430Nm of torque anywhere between 1450rpm and 2860rpm. That gives the engine great flexibility, but the transmission also plays a part.

That’s either a six-speed manual or a nine-speed dual-clutch unit. The latter has either manual or fully automatic shift modes, and it’s worth is backed up by the potential for lower fuel consumption thanks to the inherent efficiency in such a transmission as well as the three extra ratios.

Designed and made in-house at Isuzu, the brand says it’s confident the wet-clutch unit doesn’t carry the potential flaws of some other dual-clutch units we could name. That said, Isuzu has downgraded the towing capacity from 4.5 to four tonnes if the nine-speed is fitted.

And just like any good truck, there’s the provision for a power-take-off on the side of each transmission option, as well as an exhaust brake to help the mechanical brakes when fully laden.

Unlike many light trucks before it, the Isuzu doesn’t get stuck with a rigid front axle. Instead, you get a proper independent set-up with coil springs, while the rear end remains a live axle with leaf springs in the interests of carting lots of heavy stuff.

The Triton’s 2.4-litre four-cylinder diesel engine is equipped with two turbochargers that work in sequence to boost efficiency, with the smaller one providing fast response at low rpm and the larger one optimising performance at higher rpm. The result is 150kW of power at 3500rpm and torque peaking at 470Nm between 1500-2750rpm, using AdBlue to minimise emissions.

It’s paired with a six-speed torque converter automatic that offers the choice of sequential manual shifting, which can be preferable when hauling and/or towing heavy loads, particularly in hilly terrain.

The 4x4 system is dual-range, part-time offering 2H (2WD High Range), 4H (4WD High Range) and 4L (4WD Low Range) controlled by a dial on the centre console. However, you need to step up to the GLX+ to get a rear diff-lock.

This is a cursed subject in the truck segment, because there’s just no standard pattern of usage, nor a typical loading scenario. Some trucks will spend their whole lives heavily loaded going from red light to red light, others will be less burdened and driven between regional towns.

But what we can tell you is that unladen and driven sensibly, this truck should be able to return fuel consumption figures in the low teens per 100km. Throw the full payload and a trailer on the back and head for hilly country and you could easily double that and then some.

As such, the range from the 100-litre fuel tank is going to vary enormously, but should be somewhere between 500 and 800km.

The other thing to bear in mind is that the upgrade to this model has brought the Isuzus in line with Euro 6 emissions or their Japanese equivalent. So they now need AdBLue and there’s a 14-litre tank for that.

Mitsubishi claims official combined average consumption of 7.7L/100km but the dash display was showing 9.9 at the completion of our 316km test, which included the usual mix of suburban, city and highway driving of which about one third of that distance was hauling its maximum payload.

Our own consumption figure, calculated from fuel bowser and tripmeter readings, came in higher again at 10.7L/100km which is on the borderline of the usual 2-3L/100km discrepancy between manufacturer claims and real-world consumption.

So, based on our own numbers, the test vehicle should have a real-world driving range of around 700km from its 75-litre tank.

Actually climbing aboard the Isuzu is job one, and you’ll need the handles and step to do it safely. Then again, it’s probably no more testing than getting into a really low sports car in a degree of difficulty sense.

With that accomplished, you’re met with two things; the view out and the very un-car-like driving position. The first is fantastic for forward vision. And it’s not just the height advantage over other traffic. The cab-over-engine layout also means you’re almost at the very front of the truck, meaning you can see a lot more of what’s directly in front of you, even if it’s almost under your nose. Jumping back into a dual-cab ute for comparison emphasises the point enormously.

The driving position, meanwhile, might take more getting used to. The steering wheel is almost flat and you tend to sit pretty upright. Long-distance drivers will tell you this is actually great for long stints at the helm, and it honestly feels pretty natural after just a few minutes. But the steering column placement means there’s no chance of left-foot braking which some drivers (this one included) prefer.

Once you’re rolling, the dual-clutch transmission starts to feel pretty handy with short, sharp upshifts and a calibration that sees it keen to downshift on deceleration to help balance the vehicle, take the stress off the brakes and ensure that the engine is in its power band for when you next throttle on.

Speaking of which, the engine is not exactly overpowering, but it does produce the meat of its muscle in the right places, helped no end by having nine ratios to play with. And here’s an interesting point: The way the engine is installed in the NPR – and despite the fact that you’re sitting pretty much right on top of it – there’s less noise and vibration from the 3.0-litre than in an Isuzu D-Max ute. Obviously, low vibrations and less noise are factors in staving off driver fatigue, and clearly Isuzu knows how to achieve this.

Ride quality will vary hugely depending on what’s on board. We tried the NPR with a full load of gear on the tray, taking it almost to its payload limit. At that point, the ride was actually quite compliant, and the only odd sensation is that of having your backside right over the front axle.

The other mantra held dear by fleet managers is that the best way to reduce breakdowns is to take the driver out of the equation as much as possible. That explains the dual-clutch transmission, for one, but it also perhaps explains why the NPR is set up to be actually very easy and simple to drive. It’s definitely scarier to look at than to pilot. And that turning circle is something else!

Large assist-handles on the A (and B) pillars, combined with the accessory side-steps on our example, make it easy to climb aboard and find a comfortable driving position.

The unladen ride is firm, as you’d expect given its 6.0-tonne-plus GCM rating, but it’s still supple enough to soak up the bumps without the harsh kidney-belting ride suffered in some cab-chassis one-tonners we’ve tested.

This is no doubt helped by the accessories fitted, which provide more than 400kg of additional sprung weight to engage the heavy-duty rear springs and improve the ride quality. That’s something to keep in mind if you often drive unladen.

The steering is firmly weighted and the brakes have good response, with the rear drums offering a terrier-like bite when the manual handbrake is applied on steep hills with a heavy load on board.

The four-cylinder 2.4-litre diesel, with its sequential turbocharging and strong outputs, provides energetic all-round performance with efficient gearing that ensures its operating within its peak torque band most of the time.

However, at highway speeds it does tend to hold top gear for too long, when the engine has dropped below 1500rpm and is clearly wanting a downshift.

To test its payload rating, we strapped 650kg on the tray which when combined with accessories and crew was right on the weight limit. The stout rear springs compressed only 25mm under this load, leaving ample bump-stop clearance that assured there was no bottoming-out on our test route.

The Triton handled this task with competence, maintaining good performance and chassis stability. It easily hauled this load up our 13 per cent gradient, 2.0km set climb at 60km/h, with the six-speed auto self-shifting down to third gear and 2500rpm which was comfortably within its peak torque band. Engine braking on the way down was also commendable.

Our only gripe is the driver distraction monitoring system which is still too reactive in certain situations, like scratching an itch below my eye even though I was looking straight ahead while doing it. Even though Mitsubishi has tried to improve this system, it needs more refinement, as it detracts from an otherwise positive driving experience.

The Triton comes with a five-star ANCAP rating (tested 2024) and a suite of passive and active features highlighted by eight airbags (including side-curtains), auto emergency braking (AEB) with pedestrian/cyclist detection and junction assist, rear AEB when reversing, front/rear cross-traffic alert, traffic sign recognition, adaptive cruise control, lane-keeping, front/rear parking sensors, reversing camera, trailer stability assist and lots more. Rear seat has ISOFIX child-seat anchorages on the two outer rear seating positions and three top-tethers.

Despite the hard life many trucks are destined to live, Isuzu offers a standard six-year/250,000km warranty on the cabin and chassis of this model. The rear RTW body (whatever form that takes) is covered for three years. There’s also a three-year warranty on genuine accessories provided they were installed by a certified fitter.

Service intervals are every 25,000km, 12 months or 5000 hours of operation, whichever comes first. There’s also six years of roadside assistance thrown in.

Isuzu offers a range of service agreements ranging from the basic package right up to a plan that covers everything including wiper blade replacement.

There are currently 84 Isuzu dealers or authorised service outlets around the country, including some pretty far flung spots, so service and parts should be less of a problem than for some other brands.

Mechanically, Isuzu has worked to reduce servicing times, including the use of sealed-for-life wheel bearings.

It comes with a five-year/100,000km standard warranty, or 10 years/200,000km if serviced at Mitsubishi dealers.

Scheduled servicing is every 12 months/15,000km whichever occurs first. Pricing is capped at $6860 for 10 scheduled services up to 10 years/150,000km, or an average of $686 per service.

Mitsubishi currently has more than 200 dealers across its national network that spans metro, rural and regional areas. Mitsubishi dealerships are also service centres.
