Hyundai Nexo vs Isuzu NLS

What's the difference?

If nothing else the Nexo is a brilliant experiment to prove there can be more than one solution for a zero-emissions future. A lot of this depends on the power grid being more sustainable, but the most pressing issue for end-consumers, and Hyundai itself when it comes to FCEV technology, is the rollout of a more robust refuelling network.

At the end of the day, the thought of having an electric car with the range and refuelling ease of a petrol one is a much easier sell than the tall retail prices and compromises that come with an EV for every-day Australians. In a way, then, the Nexo is functionally an ideal blend of the old and the new. 

You can’t buy one yet, but as this SUV will lay the groundwork for hydrogen’s future, we’ll be watching it with a keen eye.

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.

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

Like Toyota’s Prius, the Hyundai Nexo is not only a technology leader for the brand, but it also debuted many of its current exotic design elements long before they arrived on any mainstream model. 

A little larger than a Tucson, the Nexo has a dramatic honeycombed grille which maintains a paint finish, topped off with a strip of LED lighting which Hyundai says was to give it a distinctive look at night.

All its lighting is LED to fit with its avant-garde design, although when seen from the side or the rear it could be any mid-size SUV. 

There’s something sensible about that. The Nexo isn’t the kind of car which will polarise buyers because of its design alone.

Hidden away are very neat design elements, like functional air dams on the front guards and rear spoiler fitment, and hidden wiper blades under the bonnet cladding and tucked under the rear spoiler. 

There is also intricate pattern-work on the light fittings, making for an admirable overall attention to detail befitting such an interesting, if typically shaped, SUV.

Inside, and Hyundai points out that the Nexo was the first of its cars to get the 'bridge' centre console which now appears on the Santa Fe, Palisade, and Kona EV. 

It’s an impressive design element, really lifting the cabin ambiance on all the vehicles it appears on, although the plethora of buttons smattered across its face is reminiscent of older Porsche models, and not necessarily in a good way. It can be tough for first-time or occasional users to find the button they’re looking for.

The Nexo was also one of the first Hyundai models to score the impressive dual screen layout, consisting of a 7.0-inch digital instrument cluster, and a 12.3-inch multimedia touchscreen.

Trim options for our market consist of a two-tone cream or a navy blue leather-appointed upholstery.

Again, there are attention-to-detail elements here, with interesting grain designs across the dash-topper and door cards, with many of the fittings appearing in silver rather than black to add a touch of futuristic flair. 

Hyundai promises sustainable 'bio-based' plastics are used extensively in the interior, leading to a 12kg reduction in CO2 emissions during the production process. 

There are also vegetable oil-derived paints used in the cabin, and fibres made using corn and sugarcane waste material. Nice to have some real eco bragging rights on something a lot cheaper than a BMW i8.

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.

Being a mid-size SUV, the Nexo will possess many of the practicality attributes today’s buyers are searching for.

It has a similar right height and seat positioning to a Tucson, so it’s really bang-on for the market, and headroom despite a standard sunroof is excellent. Adjustability is also good with telescopic adjust for the wheel and 10-way electrical adjust for the seats. 

As is typical for Hyundai there are some great storage areas, with a large centre console box, a single large bottle holder and odd little storage tray, a huge cutaway underneath the console bridge (which houses the wireless charger and USB ports).

There are also large door bins, although these proved not so great for holding bottles as the door design and speakers limit the height of objects that can be placed there. 

There’s also an odd little pop-out bottle holder on the passenger side, I assume to make up for the fact that there isn’t a second one in the centre.

The back seats had a good amount of room, behind my own (182cm/6'0" tall) driving position my knees had plenty of airspace, although the presence of a 'transmission tunnel' which eats space for the middle seat was puzzling given this car is strictly front-drive only. 

Amenities for rear passengers include pockets on the backs of the front seats, a single 12V power outlet, and dual adjustable air vents. There are also small single bottle holders in the doors.

Boot space comes in at a competitive but not stellar 461-litres (VDA), or 1466L with the seats down. This is okay for the mid-size segment, although the loading lip and boot floor is quite high due to the presence of under-floor batteries. 

There is also no spare wheel for the Nexo, with only a small amount of room for a tyre repair kit.

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.

Like the rest of the N Series line-up, the NPR Tradepack model we’ve chosen to review here is available in a range of cabin widths and wheelbases and even a choice of Gross Vehicle Mass. But first, let’s break down the badge. In Isuzu-speak, N stands for the smallest family in the light-truck line-up. As such, it can be driven on a normal car license in Australia.

The P stands for the GVM, in this case that license-friendly 4.5 tonnes, although you can opt for the higher, 6.5-tonne GVM at which point an endorsed license is required.

And, finally, R is Isuzu’s in-house code for a truck that is two-wheel-drive and uses conventional steel-spring suspension rather than air suspension.

Isuzu says the Tradepack option with its large tray and fittings is a very popular one, so that’s what we’ve concentrated on here. That pack equates to all the drop-side tray, racks and fittings, so it’s a comprehensive add-on. Of course, you can take your NPR as a bare cab-chassis, too, and save by swapping over the tray and fittings from your old truck.

Beyond the nuts and bolts stuff, the NPR includes LED lights all-round, heated and powered exterior mirrors (and they’re huge), keyless entry and start, cruise control, steering-wheel mounted controls, climate-control air-con, a suspension driver’s seat and a tilt and reach adjustable steering column. There’s also a 10.1 inch multimedia screen in the centre of the dashboard, digital radio, sat-nav and wired Apple CarPlay and Android Auto connectivity.

The features that tell you this is still a truck and not a passenger car include the steel wheels, cloth seat trim and vinyl flooring.

As it sits, the NPR Tradepack costs $86,014 on the road, but that’s an all-up figure, and not one where you then have to arrange your own accessories and bits and pieces. It’s also within a few hundred dollars of the Ford Ranger Super Duty Super Cab which, perhaps not so coincidentally, has an identical GVM of 4000kg, GCM of 8000kg and slightly more towing capacity of 4500kg versus the NPR dual-clutch’s 4000kg.

The Nexo’s hydrogen system is not really a drive component. It generates power for the electric motor, which is similar to the one that appears in the Kona EV. 

Like other EV models, it’s a permanent magnet synchronous motor mounted on the front axle, producing 120kW/395Nm. 

The hydrogen system is a grid of catalyst membranes which are essentially used like a giant battery to chemically combine oxygen sourced from outside the car with pressurised hydrogen. 

This reaction generates two bi-products: electricity and water, the latter of which exits the Nexo’s tailpipe.

The hydrogen system is capable of generating 135kW, just over the motor’s total output so there is always power to spare.

Powering the car’s auxiliary systems, and acting as a buffer to store excess and regenerated energy, is a hybrid-sized 1.56kWh lithium-ion battery under the boot floor.

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 Nexo drinks compressed hydrogen. It has 6.33kg worth of hydrogen storage tanks which grant it a generally EV-beating 666km of range. 

One of the key benefits of the hydrogen system is that it refuels in roughly the same time as it takes to fuel a diesel car, using a pressurised hose in a similar manner to an LPG vehicle.

The trouble is hydrogen is hard to source at a pump in Australia. There is one refuelling station at Hyundai’s Macquarie Park HQ in NSW, another just opened in the ACT, and a third one owned by Toyota which is about to open at its Altona, VIC HQ.

The fleet of 20 cars handed over to the ACT government will use the new pump, which for the first year will be providing free hydrogen as the system is evaluated.

Overall costs for the hydrogen after that time will depend on where it is sourced from. As Australia is uniquely positioned to generate compressed hydrogen (with an abundance of renewable energy idle time which can be stored in places like the ACT) the cost will come down over time. 

Right now, though, the brand estimates somewhere to the tune of $15 a kilo for an end-consumer, or about $90 to fill the Nexo.

Finally, a benefit for the eco-conscious, Hyundai pitches the Nexo as a product which actually leaves the air cleaner after generating energy, although there are some caveats.

The first is that the membrane requires use of platinum – a rare earth metal, and the second is hydrogen requires a lengthy, power-intensive and complex process to generate in a usable form. 

In the ACT government’s case this is less of a problem, as it will use 100 per cent renewably sourced idle energy to process the gas.

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.

To drive the Nexo is essentially no different to an electric car. It uses the same permanent magnet motor, the same regenerative braking, and the same buffer battery system.

This means a very quiet and smooth drive. It’s not quite the unleashed performance of a Tesla, but then that’s not really the point of the Nexo which leans into the comfort of the whole experience.

The drive and hydrogen reaction is entirely a silent process, although the Nexo emits a pleasant choral tone at low speed to alert passers by of its presence, same as the Kona EV.

Despite that strong torque number, the Nexo isn’t inclined to spin the wheels, and for balance reasons, Hyundai actually de-tuned the motor slightly to make it gentle off-the-line.

When it comes to corners the comfort is again emphasised, with very light and linear steering. The chassis is rigid enough to feel under control, although the comfort suspension tune will have it tilting around a little more than, say, a Tucson.

The ride is also far more forgiving than Hyundai’s sportier petrol range, with the Nexo undulating over bumps and corrugations with ease.

As is usual with Hyundai models, the safety systems aren’t too invasive, making the Nexo a friendly companion on the freeway, and the soft interior trimmings add to its near-luxurious feel.

The ACT government reps who will be receiving this car are of the mind that anybody that drives it will become an advocate for electrification, and I’m inclined to agree with them.

For most people it’s better in every way from behind the wheel when compared to a petrol car.

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!

You can absolutely thank OH&S legislation for the huge leaps in active and passive safety that vehicles like the Isuzu have made in recent years.

Although this class of vehicle is not required to be crash tested (and, therefore, there’s no safety star rating available) even a scant knowledge of physics suggests that sitting the passengers up high in a vehicle with a strong chassis is a very good start when it comes to crash safety.

Passive safety is also helped by an airbag for both driver and the two front-seat passengers in the case of the three-seat variant we’ve looked at here. But only the outboard passengers get a three-point seat-belt, and the centre position gets a simple lap-belt.

There are also side intrusion bars in the doors as per passenger-car best practice and the overhead storage space features a safety net. There are no side-curtain airbags, but again, that high seating position makes the N Series inherently safer for passengers in a typical side impact.

But it gets better with a long list of driver aids, most of them straight out of the current passenger-car playbook. Running changes to the vehicle over the years have seen the addition of autonomous emergency braking (AEB), anti-skid brakes, stability control, a driver attention monitor, a distance warning system for vehicles in front, brake-force distribution and lane departure warning.

New safety tech this time around includes front cross-traffic alert and braking, mis-acceleration (pedal-error) mitigation, traffic and speed-sign recognition, a distance warning system that also advises of the speed of the car in front and improvements to the rear camera system.

And yet, there’s probably more work to be done here. We’d like to see a standard 360-degree camera and tyre pressure monitoring as well. These are both available at extra cost right now, but really should be standard on a vehicle like this. Rear cross-traffic alert is also missing, but that’s more about standardising the sensors and their calibration on a huge range of rear-body designs, apparently.

There’s also an apparent tech gap to be bridged, too, and right now only the dual-clutch-equipped version gets the speed limiter and adaptive cruise control, while the conventional manual does not.

Isuzu is also making a big noise about the new electronic park brake which can be used in an emergency to bring the vehicle to a complete, controlled stop if necessary.

Ownership is a tough one, because, well, you simply can’t own one. 

Either way Hyundai says the Nexo’s hydrogen drivetrain carries no warranty implications, meaning if you could own one (as Koreans can), it would still be covered by the brand’s five year/unlimited kilometre warranty.

In terms of servicing, the Nexo requires a visit once a year, although like a pure EV there are few items that actually need attention at one of these visits.

A top-up of coolant is only required about once every six years, and various filters need to be cycled out. Other than that, it’s just your usual wear and tear items like brakes and tyres.

As Hyundai leases the current vehicles out, it will be taking care of servicing for the initial batch.

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.
