Nissan Z vs Isuzu NLR

What's the difference?

The Nismo turns up the wick just enough to justify its $20K premium over the brilliant regular Z.

Visual changes inside and out are one thing, but with tangible boosts in performance, handling and braking – with no detriment to ride quality or comfort – as a result of properly engineered upgrades, the RZ34 version deserves its place in Nissan’s sports car hall of fame.

Note, though, that good as it is, the Nismo is also a potent reminder of how solid a foundation the standard Z also is… especially in manual gearbox guise.

Work out the weight of all the tools, equipment, materials, crew and (if applicable) trailer that you need to haul around each day and measure it against this truck’s formidable GVM and GCM ratings. When combined with its compact dimensions, robust design and build quality, solid warranty and ready-to-work pricing, you may find it’s hard to beat if you’re prepared to think outside the square on what a single cab-chassis ute can look like.

Reinterpreting a classic via retro styling isn’t always successful – hello, 2001 Ford Thunderbird ­– but what Nissan has achieved with the RZ34, given it’s a pastiche of several Z greatest hits from the ‘70s, ‘80s, ‘90s and today, is truly masterful design.

Take the cab-backward silhouette, long nose and short wheelbase; it somehow manages to deftly capture the spirit of previous Z generations, without looking like a bad caricature.

Points especially go to the stunning nose and tail treatments that evoke both the ‘70s 240/260/280 as well as the sadly long-forgotten Mid-4 II concept car of 1987.

Slightly longer than the regular model, the Nismo’s nose is meant to evoke the early ‘70s Japan domestic market Fairlady ZG, with the G denoting “Grand Nose”. Fun fact: Fairlady first appeared on the 1960 Datsun roadster as deference to the Broadway musical (and later Audrey Hepburn film, presumably) ‘My Fair Lady’.

Anyway, besides scraping speed humps and driveways, the Nismo’s elongated front bumper promotes improved engine cooling and better aero flow, as do the side sills, larger wraparound three-piece spoiler and redesigned rear bumper/diffuser. The wider-yet-lighter back wheels are 10mm wider. And a glossy red stripe runs along the underside like Anna Nicole Smith’s lipstick.

Does it all look better than the simpler, purer regular Z? No. But they perform better. And isn’t that the point of a Nismo?

This vehicle looks compact in comparison to a one-tonne ute - and the tape measure confirms it. Compared to a Ranger 4x4 dual cab ute for example, its 5020mm overall length is a surprising 339mm shorter, its 2490mm wheelbase is 730mm less and its 1855mm width is line-ball.

The Isuzu’s 2172mm height is 357mm taller, which could present a challenge if access to underground or multi-storey carparks is required. However, its remarkably small 8.7-metre turning circle is a whole 4.0 metres tighter than the Ranger, so it's highly maneuverable.

Built on a heavy-duty steel ladder-frame chassis, it has independent wishbone/coil spring front suspension, a leaf-spring live rear axle, power-assisted rack and pinion steering and four-wheel disc brakes. It also runs a 24-volt electrical system with twin batteries.

The single cab provides fabric-trimmed seating for up to three (driver bucket, passenger bench) but our test vehicle was fitted with seat covers from the Isuzu accessories range. With torsion bar assistance, the cab can be easily tilted forward to rest at a 45-degree angle and provide full access to the engine.

The service body, which is a blend of lightweight aluminium and steel, has a tough powder-coated finish. It comprises a large main storage compartment with big gull-wing doors on each side, plus a compact rear tray with checker-plate floor, drop-sides and load anchorage points. There are also rear underbody storage boxes on each side, plus sturdy body-mounted roof racks, safety yellow non-slip steps and sturdy grab handles front and rear.

So, just as the exterior is an anthology of past Z car stylings, the same also applies inside.

A mishmash of new and old as well, they also marry together harmoniously – after you’ve bent and contorted yourself inside nice and snug, on the racy yet not-too-unforgiving set of Recaro bucket seats.

The Z’s signature sloping roof and rising window line; a trio of dials that have been a hallmark of the series since the 240Z, a thin three-spoke steering wheel; a physical hand brake and a pair of old-school seat base angle adjuster knobs just like in sports cars from 20 years ago betray the Nissan’s ageing DNA.

But they set the mood, like hearing a favourite old track, though one remixed by a contemporary DJ to a modern beat.

Which means that you’ll be able to view whichever artist you like through the 8.0-inch touchscreen, either via Bluetooth audio streaming, Spotify or some such app.

Easy to decipher and simple to navigate (though no imbedded GPS is fitted), the Z’s dashboard also offers the essential surround-view parking camera (given how limited vision is as you’re sat so low with not much glass to peer out through), amongst a host of vehicle functions. You’re also privy to extremely useful blind-spot alert thoughtfully placed inside the car by the mirror mounts, four cupholders if you count the door-sited ones and surprisingly generous storage. Practicality, thy name is Fairlady.

For lightness and sensible packaging, we understand why Nissan’s sports coupe is strictly a two-seater proposition – and certainly a roomy enough one for the lucky pair at that.

However, it’s a shame Nissan doesn’t offer a 2+2-seater option in the form of a pair of occasional jump seats behind, as per the old Datsun days, as there seems to be just enough space for smaller folk – though as a pair of shelves, that area did prove very useful during our week with the Nismo.

Issues? Along with a sheer lack of grace entering and exiting the Z, poor overall vision and 350Z-era switchgear that are now old enough to drive themselves, finding the right driving position eluded this particular 178cm tester. The seats do a great job keeping you firmly fixed in place, and of course the wheel tilts and telescopes, but those pair of knobs were forever being twirled and fiddled with.

Oh, and simultaneously unlocking and opening the doors was also confounding, due to exterior door handles and pressure sensor not designed for Homo Sapien hands.

Further back, and as in the two previous generations Zeds, a brace bisects the luggage area. Rated at 241 litres VDA, it is wide and flat but a wee bit shallow. At least it adds another level of practicality and is big enough for those weekends away.

There’s no cover (though seeing what’s inside isn’t easy) and no spare wheel of any size is fitted.

Meanwhile, on the other side of the Nismo…

With a hefty 2825kg tare weight and 4500kg GVM, the Isuzu has a big 1675kg payload rating. It’s also rated to tow up to 4000kg of braked trailer and with its sizeable 8000kg GCM, it can legally tow that weight with a 500kg reduction in payload. Or you can cap the towing weight at 3500kg and keep the full payload. Either way, these are substantial GVM and GCM ratings for any number of working roles.

In terms of cabin storage, there’s no glove box but both doors have narrow storage bins and there are overhead shelves with restraint netting to keep loose items in check. There’s also a pop-out dual bottle/cup holder in the centre dash along with two small storage nooks, but more places to store things would be welcome in this space.

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.

Nissan sure knows how to make a great six-cylinder engine.

The Nismo’s internal combustion engine in question is the VR30DDTT – a twin-turbo V6 making four per cent more power and around 10 per cent more torque compared to the one found in the regular Z.

Power jumps 11kW and torque a handier 45Nm to 309kW @ 6400rpm and 520Nm between 2000rpm and 5200rpm respectively, providing extra punch as well as a slightly superior power-to-weight ratio of around 184kW per tonne.

That’s up 2kW/tonne, despite the Nismo gaining around 50 kilos, to 1680kg.

This has been possible thanks to extra turbo boost, revised ignition timing, improved cooling systems and updated engine management software.

Driving the rear wheels is a Mercedes-Benz based nine-speed torque-converter auto. Upgraded and retuned for track use, it includes a Sport+ mode providing speedier shift responses. Aided by the new launch control function, we managed a tidy 4.5 seconds from standstill to 100km/h.

Sadly, though, there’s no manual option as per the regular Z.

What else is unique here? Underneath, the platform might date all the way back to the 350Z of 2003, but Nismo has really worked some of its magic.

Along with the retuned dampers, everything else has been stiffened up – including the anti-roll bars, springs, bushes and even the steering rack mounts – to help deliver more controlled and linear steering. There’s extra underfloor bracing at the front, centre and rear of the car, thicker brake rotors and model-specific Dunlop SP Sport Maxx GT600 tyres that are wider at the back, on gloss-black RAYS alloys.

Continuing to use a double-wishbone front and multi-link rear suspension set-up, the Z’s front/rear weight distribution is 56/44 front/rear.

Now, the Nismo was our favourite version of the previous 370Z by some margin. How does it all square up in RZ34 guise?

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.

Not surprisingly, the Z Nismo needs to drink from the 98 RON premium unleaded petrol fountain.

Nissan reckons owners should expect to average 10.4L/100km (for 242 grams per kilometre of carbon dioxide emissions) on the combined cycle (and 15.0 and 7.7 L/100km for the urban and extra-urban ratings respectively.

This figure is almost half a litre worse than the non-Nismo Z’s 9.8L/100km result, but still substantially better than the six-speed manual base grade’s 10.8L, despite the latter being some 33kg lighter.

With a sizeable 62L tank, you might be able to average just under 600km between refills.

For the record, we achieved 11.9 litres per 100km in a mix of urban, freeway and performance driving which is not too bad at all given how often we fanged this thing.

Average combined fuel consumption figures are not required for commercial vehicles in this weight division. Even so, the dash display was claiming 13.2L/100km at the end of our 295km test which included about one third of that distance hauling a heavy payload. So, based on those figures you could expect a real-world driving range of around 570km from its 75-litre tank.

Nissan does plenty of things really well, and the Nismo is no exception.

Firing up the VR30DDTT 3.0-litre twin-turbo V6 is also a reminder of how brilliant the brand’s six-cylinder engines are. They tingle all the right sensory areas, starting with the baritone rumble at idle.

What a portent of what’s to come!

Nismo’s massaging of the engine, combined with upgraded clutch packs and a retune of the nine-speed auto’s software, results in stronger, hungrier and angrier acceleration, no matter which of the three driving modes you’ve selected. Even in Normal, the Nissan leaps off the line. In Sport, its appetite for speed is palpable. In Sport+, this thing is eating up the tarmac. Somehow, in an EV era where 4.5s to 100 is ho-hum, the (electronically enhanced but who cares) guttural exhaust bellow seems to amplify the action and thrills.

And spills. For five of our seven days together, the heavens poured. Now, in Normal mode, the Nismo was as benign and controlled as you’d hope in wet conditions, the driver-assist tech metering out just enough torque and braking to seamlessly keep the car humming along. Ever-present but always nuanced, they’ll help make your commute a safer and more relaxing one.

Selecting Sport loosened things up markedly, with the driver needing to be ready to counteract with steering, seating and throttle, though still with a safety net to keep the car from going totally out of whack; Sport+, meanwhile, is not for amateurs or the distracted. This is serious, tail-wagging waywardness that should only be fully explored with experience and care.

Later in the week, Launch Mode in Sport+ on cold but dry bitumen also requires super concentration, as we discovered attempting to extract the fastest acceleration time. Sideways in a straight line at 100km/h-plus is not for the faint hearted.

Beyond all-out performance and drama, the Nismo soars with weighty yet linear and precise steering, resulting in satisfying, hunkered-down handling that is the hallmark of a great sports car. Really tight turns can be taken at impressive speeds, but there’s about 1.7 tonne of muscle to manipulate, so the real fun can be found blasting along a snaking set of more open corners, where the Z’s inherent thrust, poise and grip come into play, all to the symphony of that bi-turbo V6.

That the suspension can feel both firm and supple at the same time is another arrow in the Nismo’s bow.

Nissan isn’t pretending this is anything but a rousing and rapid grand tourer with track aspirations, so the fact there’s also comfort and sophistication to be enjoyed just shows the sheer bandwidth of this particular Z.

Downsides? There’s always a wall of sound, be it mechanical or noise intrusion from the rubber and/or bitumen. The Nismo is rarely quiet. The extended front spoiler seems to summon up speed humps and bumps you never knew existed. The adaptive cruise control’s inability to resume in heavy stop/start traffic betrays this car’s 350Z-era tech. And the lack of a manual transmission, we reckon, is a missed opportunity for an even greater degree of interactive sports car driving.

Still, the Nismo delivers exactly what the brand promises, and continues to improve a firm favourite for speed and drama.

But the gap between Nismo and regular model is smaller than the one that existed in the preceding 370Z, which means that – if $100K driveaway is too steep – you’re already driving something elevated in the standard Z. Particularly if you yearn for a manual.

It’s all good.

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.

Your wallet’s pretty secure as well.

Like all Zs, the Nismo is subject to a warranty period of five years with unlimited kilometres, while service intervals are fixed at every 12 months or 10,000km – whichever occurs first. There is also five years of roadside assistance.

Nissan also provides pre-paid maintenance plans that can save up to $245 over three years, as well as capped-price servicing. At the time of publishing, the capped-price service appointments cost between $347 and $950 depending on the year of ownership.

There's a reassuring standard warranty of six years or 250,000km (unlimited operating hours) whichever occurs first. Includes three years/unlimited km coverage for body equipment, plus six years of 24/7 roadside assistance with unlimited km. Scheduled servicing every 15,000km/12 months whichever occurs first. Choice of servicing packages available.
