Isuzu NLS vs Nissan Navara

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.

The D27 Nissan Navara represents badge engineering at its best or worst, depending on your point of view regarding platform sharing. However, when assessed purely on its merits as a standalone tool of trade, the entry-level SL is a competent and economical workhorse that’s worthy of at least cross-shopping with the major players.

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.

It looks like a base model Triton GLX given the Navara SL’s modest front and rear styling tweaks, which are not as substantial nor convincing as platform-sharing rivals like Mazda’s BT-50 or Volkswagen’s Amarok in creating a clear visual distinction from its donor.

Nissan has been equally economical with interior changes. Even so, the work-focused cabin is functional and reasonably spacious for a dual cab, with splashes of satin chrome combined with white upholstery stitching and fake carbon-fibre surfaces providing a touch of style to predominantly grey tones.

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 its 2126kg kerb weight and 3190kg GVM our test vehicle has a useful 1064kg payload rating, so it’s a genuine one tonner.

It’s also rated to tow up to the class-benchmark 3500kg of braked trailer but with its 6250kg GCM rating (or how much it can legally carry and tow at the same time) it would require a sizeable 440kg reduction in vehicle payload to tow its maximum trailer weight.

Not that many (if any) owners of utes this size would need to tow 3500kg but it’s important to be aware of these numbers when towing heavy trailers to avoid dangerous and illegal overloading.

The Navara’s load tub is almost square with its 1555mm length and 1545mm width. It’s also 525mm deep and with 1135mm between the rear wheel housings it can’t fit a standard Aussie pallet but will carry a Euro.

Our test vehicle does not come standard with a tub-liner so its painted surfaces are prone to scratches and dents. There’s four anchorage points for securing loads and the tailgate assist feature allows easier lowering and raising.

The driver and front passenger share good space and comfort, with storage that includes a bottle holder and bin in each door plus a large open shelf above the single glovebox and an overhead glasses holder. The centre console offers flat storage with two USB ports and a 12v socket up front, along with two cupholders in the centre and a lidded box at the back.

Rear seating is also 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 ample knee and headroom. However, shoulder room is tight for three adults, which is tolerable for short trips but a maximum of two would be preferable for longer drives.

Rear passenger storage includes a bottle holder and bin in each door plus pockets on each front seat backrest. There’s another 12v socket in the rear of the centre console and the centre seat’s backrest folds forward to serve as an armrest with dual cupholders.

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 fifth generation Navara, which is available only in 4x4 dual-cab ute configuration, comes in four model grades comprising SL ($53,348 plus on-road costs), ST ($56,765), ST-X ($63,177) and Pro-4X ($68,418) designed to cater for commercial applications through to lifestyle/recreational use.

Our test vehicle is the entry-level SL with its list pricing in the same ballpark as workhorse equivalents from major players including the Ford Ranger XL 2.0L auto ($51,130), closely related Triton GLX 2.4L auto ($51,640), Isuzu D-Max SX 2.2L auto ($52,200) and Toyota HiLux Workmate 2.0L auto ($53,990).

Like its Navara siblings it's available only with a 2.4-litre bi-turbo four-cylinder diesel engine and six-speed automatic transmission. 

The SL's work-focused standard features include 17-inch steel wheels with 265/65R17 all-terrain tyres and a full-size spare wheel, LED headlights/daytime running lights/tail-lights, tailgate assist, 360-degree camera and front/rear parking sensors to name a few.

The interior is also designed with hard work in mind with its wipe-clean vinyl floor and black fabric trim but there’s also creature comforts like remote keyless entry, single-zone climate control, second-row air vents, power-adjustable lumbar support for the driver’s seat, multi-function steering wheel controls and more.

There’s also multiple USB ports and 12v sockets, a 7.0-inch instrument cluster display and a 9.0-inch touchscreen to control the four-speaker multimedia system which includes wireless Apple CarPlay and Android Auto connectivity and DAB+ digital radio.

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 Navara’s 2.4-litre four-cylinder ‘bi-turbo’ diesel engine is equipped with two turbochargers which work in sequence to boost efficiency, with the smaller one providing fast response at low rpm and the larger one optimising response at higher rpm.

It produces 150kW of power at 3500rpm and its sizeable 470Nm of torque is served at full strength between 1500-2750rpm. It’s also Euro 6B emissions compliant using AdBlue.

This is paired with a six-speed torque converter automatic, offering 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) selected by a dial on the centre console, where you’ll also find a button to engage the locking rear diff.

The most significant differences between the Triton and Navara are in suspension design and tuning, with the D27 Navara replacing the previous D23 generation’s coil-spring rear end with the Triton’s more traditional leaf-spring arrangement.

Nissan has also collaborated with Melbourne-based engineering partner Premcar in developing three unique suspension tuning packages focused on damper (aka shock absorber) refinement, aimed at enhanced steering response, handling stability and ride comfort.

The premium Pro-4X and mid-grade ST-X each have unique settings while the work-focused SL and ST share the same calibration designed for hauling loads, including heavy-duty four-leaf rear suspension. All model grades also feature electric power steering.

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.

Nissan claims combined average consumption of 7.7L/100km but the dash display was showing 9.4 at the completion of our 496km test, which included our usual mix of suburban, city and highway driving of which about one third was hauling a near maximum payload.

Our own consumption figure, based on fuel bowser and tripmeter readings, came in slightly lower at 9.1L/100km which is comfortably within the usual 2-3L/100km discrepancy between manufacturer claims and real-world consumption and excellent economy from mostly metro driving.

So, based on our test results, we estimate the Navara SL has a real-world driving range of more than 800km 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 handles on the A pillars assist climbing aboard into a comfortable and spacious driving position, enhanced by steering wheel and seat adjustments (including power lumbar support) plus a left footrest, which ideally could be a tad wider.

The claimed ride and handling changes resulting from Premcar’s suspension tuning are so seamless they would be hard for most Navara drivers to define. All that matters is how it feels behind the wheel.

And I must say it’s a nice thing to drive, which is consistent with all the Premcar-enhanced D23 Navaras we've tested before it, combining excellent steering feel with supple yet responsive ride and handling whether unladen or loaded.

The switch to electric power steering also provides a noticeably light turning effort when parking which becomes increasingly firm with a stronger self-centering effect at highway speeds, like all variable-ratio systems should.

The six-speed auto’s gearing optimises performance in urban use by keeping the engine operating within its peak torque band most of the time, which ensures a consistently energetic response. It’s also a relaxed highway cruiser, requiring less than 2000rpm to maintain 110km/h where low noise levels allow conversations without raised voices.

To test its GVM rating we forklifted 650kg into the load tub, which combined with our crew of two equalled a total payload of 830kg that was still more than 200kg below its legal limit. The heavy-duty rear springs only compressed about 30mm under this loading, which ensured ample bump-stop clearance and no bottoming out on our test route.

Its handling remained surefooted and predictable when hauling this payload, which, combined with the Navara’s hearty 470Nm, ensured it made light work of our 13 per cent gradient, 2.0km long set climb. It also provided strong engine braking on the way down, so overall it proved to be a competent load hauler.

The only negative from a driver’s perspective is the Navara’s inheritance of the Triton’s annoying driver distraction monitor, which even beeped and prompted me to ‘please look forward’ when I dared to look at the central and passenger door mirrors when overtaking another vehicle. Seriously? It’s ironic that a driver distraction monitor can be distracting, but it is.

The Navara has a five-star ANCAP rating (tested 2024), and comes with eight airbags, auto emergency braking (AEB) with pedestrian and cyclist detection and junction assist, front and rear cross-traffic alert, traffic sign recognition, adaptive cruise control, lane-keeping, front and rear parking sensors, 360-degree/reversing cameras, trailer stability assist and lots more.

The rear seat has ISOFIX child-seat anchorages on the two outer 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.

The Nissan Navara comes standard with a five-year/unlimited kilometre warranty but up to 10 years/300,000km with matching roadside assist is available if the car is serviced at Nissan dealers.

Scheduled servicing is every 12 months/15,000km with capped pricing applicable for the first five scheduled services totalling $2495, or an average of $499 which is competitive with numerous well established rivals.

Nissan Australia has a large network of around 180-200 dealers which includes every state and territory.
