Isuzu MU-X vs Nissan X-TRAIL

What's the difference?

The MU-X has always had plenty of appeal as a daily driver – dependable, not dynamic – and it’s a proven 4WD wagon.

Some people don't like the noisy, sluggish engine, but I don't mind it because it delivers off-road.

There was already a lot to like about the seven-seater wagon in terms of its off-road capability, driver-assist tech, standard features, and simple all-round driveability, and the X-Terrain – which encompasses all of that AND adds some polish to the mix – is an impressive top-shelf addition to the MU-X line-up. Even if it's so pricey...

Over four generations Nissan has fine-tuned the X-Trail into an impressively refined and practical option for an urban family; that practicality further extended by inclusion of two occasional seats in the third row of this N-Trek version. The value equation is also strong and safety is top-shelf.

That said, efficiency is far from class-leading and the ownership proposition is off the category pace. But this even-seater’s overall quality still shines through. 

If you’re in the midst of the mid-size SUV market vortex and want seven seats rather than five make sure this car’s on your investigation list.

As I’ve said before, the MU-X has never been particularly exciting or boring in terms of design, just comfortably adopting a low-key, middle-of-the-road type design – sales gold, in other words.

But the X-Terrain has distinctive ‘X’ branding here and there – inside and out – and that adds a subtle class to this variant.

The X-Terrain is 4860mm long (with a 2855mm wheelbase), 1870mm wide (excluding mirrors), 1825mm high and has a listed kerb weight of 2195kg.

It has a wheel track of 1570mm and an 11.6m turning circle. 

Our test vehicle has the exclusive X-Terrain paint – slate grey metallic – which matches well with the X badging, bigger grille design, new headlights, three-tier LED tail-lights, and redesigned wheels.

The interior strikes a stylish note as well with red stitching on the dash, centre console and leather-accented seat trim.

Busy but interesting is a description you might apply to a mad rocket scientist or rock ‘n’ roll roadie. But it’s also apt when looking at the Nissan X-Trail’s exterior design.

Long, angular head and front fog lights sitting either side of a large grille and above multiple air intakes set the tone at the front with a similar mix of accentuated tail-lights and jagged shapes at the rear.

There’s enough distinctive character there to identify the X-Trail as a contemporary Nissan and I for one like the look of it, especially in our test example’s ‘Ceramic Grey’ finish.

For car-spotters, the N-Trek is distinguished by specific 18-inch (mainly black) alloys, a unique front and rear bumper treatment and a blacked-out grille as well as a black finish on the door handles, mirror covers and roof rails.

This third-generation X-Trail arrived less than two years ago and the interior remains classy and restrained, Nissan so far resisting the temptation to join media and instrument displays into the increasingly common single array.

The sweeping multi-level dash is fuss-free and the muted, mainly grey and black colour palette is calming yet bright enough to avoid crossing the line into sombre.  

Its layout is simple and ergonomically efficient with details like manual dials for audio and heating/ventilation control a plus.

And it’s the things you don’t regularly notice that are worth calling out. The electric handbrake is near silent on application; not always the case in recently released rivals. The rear windscreen wiper motor is also quiet; again, something you can’t take for granted these days. And the quality of the materials across the interior is a cut above those most often used by ‘challenger’ brands.

I could go on, but you get the idea. Lots of small ‘one per cent’ things that may seem minor on their own but add up to make a noticeable difference overall.

The interior has a pleasant, familiar and practical feel about it and this is an easy space in which to swiftly become comfortable. 

Controls are easy to locate and operate and charging options are numerous – a mix of USB-A, USB-C and 12V up front, and USB-A for the second row.

Storage places include recesses for your everyday carry gear, a suitably deep centre console, as well as dual cupholders up front, cupholders in the rear fold-down centre armrest and bottle holders in the doors.

There are cupholders either side of the third row in the MU-X for passengers riding back there.

The MU-X has physical-button options to activate some functions (including to switch on the audio system, to adjust volume, access sat nav etc).

Seats are adequately comfortable and supportive through all three rows – yes, even the third row is roomy enough to prevent whining from whoever is stuck back there.

The cargo area is 311 litres with all three rows in use, 1119L with the third row flat and 2138L with the second and third rows folded.

The rear cargo area has a cargo cover, tie-down points, a 12V power outlet, a storage space under the rear cargo area floor and a space for tools inside the driver’s side rear cargo wall.

At just under 4.7m long, a fraction over 1.8m wide and a bit more than 1.7m tall, the current Nissan X-Trail is a large mid-size SUV.

That allows for a generous amount of space up front with more than enough breathing room between the driver and co-pilot.

Storage is pretty handy, too, with a decent size lidded ‘butterfly door’ box between the seats (which doubles as a centre armrest), two cupholders in the centre console, a lower level tray underneath, door bins with space for large bottles and a decent glove box.

Move to the second row and at 183cm tall I have plenty of headroom and legroom, with the latter variable thanks to the seat’s ability to slide and open up more room for the two third-row occupants if required.

Again, there are bins in the doors with a cavity able to accommodate large-ish bottles, two cupholders in the fold-down centre armrest and map pockets on the front seat backs, while adjustable ventilation gets a big thumbs up.

Three full-size adults across the second-row seat is a recipe for discomfort but two grown-ups or a trio of up to mid-teenage kids will be fine and the rear doors deserve a big shout out. 

First, they open out to 90 degrees which makes getting in and out of there s-o-o much easier and second, pull-up sunshades are always a welcome addition.

The third row is a kids-only zone, but the flexibility those two spots offer is significant and Nissan’s provision of big outer armrests with storage and drink holders built in is a thoughtful touch.

Connectivity and power options run to USB-A and -C ports (for streaming and charging) plus a 12-volt socket and wireless device charging pad in the front. There’s an identical pair of (charge only) USBs in the centre row and another 12-volt outlet in the boot. 

Speaking of which, with all seats up the seven-seat X-Trail’s boot capacity shrinks to that of an oversize handbag (realistically, two or three soft bags), but with the 50/50 split third row folded down you’re provided with 465 litres of volume (to the roof) which is enough to easily swallow the three-piece CarsGuide suitcase set. And the 40/20/40 split second row’s sliding ability again allows you to play with the space available.

Worth noting a space-saver spare is provided (a much better option than a ‘roll of the dice’ repair/inflator kit) and maximum braked trailer towing capacity is a handy 2000kg (750kg unbraked).

At $50,390, before on-road costs, other similarly sized and specified three-row rivals to the X-Trail N-Trek include the recently released Tiggo 8 Pro Max Ultimate AWD ($47,990 drive-away) as well as the Mitsubishi Outlander and VW’s Tiguan Allspace.

The N-Trek’s $50K price tag neatly dissects the Outlander 7 seat AWD Aspire ($47,340) and Exceed ($52,640) grades and splits the Tiguan Allspace 132TSI Life ($47,990) and 162TSI Elegance ($57,090) models.

As well as the safety and performance tech covered later in this review, the X-Trail N-Trek’s standard equipment list features dual-zone climate-control, a 12.3-inch digital instrument cluster, 12.3-inch multimedia touchscreen display, a 10.8-inch head-up display, built-in sat nav, wireless Apple CarPlay (and wired Android Auto), keyless entry and start and six-speaker audio (with digital radio).

There’s also a ‘leather-accented’ steering wheel, a 10-way power adjustable driver seat (manual-adjust front passenger seat), heated front seats, synthetic leather trim,18-inch alloys, auto rain-sensing wipers, auto LED headlights (all other exterior lights are also LED), power-folding heated exterior mirrors, rear privacy glass and roof rails.

That’s a solid basket of fruit for the money in this part of the market.

The MU-X has a 3.0-litre four-cylinder turbo-diesel engine, producing 140kW and 450Nm and it’s matched to a six-speed auto.

These form part of a proven powertrain and while the MU-X may not be the most dynamic vehicle to drive – it’s acceleration is sluggish rather than punchy – it has a real tractability that nullifies any other niggles.

It has part-time 4WD, with high- and low-range as well as various drive modes, rough terrain mode, and a rear diff lock.

The X-Trail N-Trek is powered by a 2.5-litre, naturally aspirated, four-cylinder petrol engine developing 135kW at 6000rpm and 244Nm at 3600rpm. Not a turbo in sight, which is increasingly rare as emissions standards for internal-combustion engine cars continue to tighten.

That said, the X-Trail’s hugely popular corporate sibling, the Mitsubishi Outlander (they share the same chassis platform) has the identical engine residing under its bonnet.

The all-alloy unit features direct-injection and electronically-controlled variable valve timing to produce outputs in the same ballpark as other category favourites like the Kia Sportage 1.6 turbo (132kW/265Nm) and Mazda CX-5 2.5 (140kW/252Nm). But the Toyota RAV4 Hybrid AWD steps ahead on power at 163kW.

Power is transferred to all four wheels via a CVT auto with a ‘Drive and Terrain Mode Selector’ offering ‘Auto’, ‘Eco’, ‘Sport’, ‘Snow’ and ‘Off-Road’ modes.

The AWD system is on-demand with steering angle, yaw rate and G-force sensors feeding into an electronically controlled coupling ahead of the rear differential able to adjust torque distribution between the front and rear axles from 100:0 to 50:50 on the fly.

Official fuel consumption for this MU-X is 8.3L/100km and that's on a combined cycle. 

On this test I recorded 10.2L/100km. I did a lot of high and low-range four-wheel driving, so that fuel consumption is not too shabby.

The MU-X has an 80-litre fuel tank, so going by my on-test fuel consumption figures you could reasonably expect a driving range of about 784km from a full tank. 

Nissan’s official combined cycle fuel-economy figure for the X-Trail N-Trek is 7.8L/100km, the 2.5-litre four emitting 183g/km of CO2 in the process.

That number’s in line with other non-hybrid competitors but some way off the Toyota RAV4’s 4.8L/100km.

Over a week covering mainly urban and suburban driving as well as some freeway running we recorded an average of 9.9L/100km, measured at the pump, while the on-board computer coughed up a more optimistic 9.1L/100km.

That’s starting to get up there for the class although the result’s balanced somewhat by the X-Trail’s ability to run happily on 91 RON ‘standard’ unleaded.

You’ll need 55 litres of it to fill the tank which translates to a theoretical range of around 700km and roughly 550km using our real-world number.

In previous tests, the MU-X has been fine on road and more than adequate on gravel, dirt tracks, and during low-range 4WDing. But it’s been a jarring, skippy ride on irregular surfaces rather than as composed as it could – and should – have been. The culprit? Firm suspension, over-inflated tyres, too-tight trousers, who knows?

The good news is it seems like Isuzu has ironed out any issues in the suspension, minor or otherwise, because the MU-X is now is a lot better in terms of ride and handling than ever before. 

Off-road, the MU-X has always been a proven combination of its 3.0-litre, four-cylinder turbo-diesel engine, clever six-speed automatic transmission, and an off-road traction control system that's been increasingly well recalibrated through a number of generations. 

The engine is tractable and gruff, it has plenty of grunt and, as long as you're not driving like a complete hoon, you can usually get through most obstacles without a lot of fuss.

It's this mix of mechanicals and driver-assist tech that make the MU-X such an effective 4WD package. And there are a number of reasons for that. 

For one, that engine delivers plenty of torque down low and in the mid-range torque and that's crucial for four-wheel driving. 

And another thing, Rough Terrain Mode – like a beefed-up and fine-tuned off-road traction control – proves very effective because it punches torque to the wheel with the most traction – while wheel spin on tyres that aren't touching dirt is minimised – and that way it keeps the vehicle moving through obstacles with safe and controlled momentum. 

As I’ve noted before though, Rough Terrain Mode is not a magic all-conquering solution, but it is another handy addition to the MU-X’s off-road toolbox.

And the MU-X also has a rear diff lock to back you up – and that's another valuable component. 

The MU-X has approach, departure and ramp-over angles of 29.2, 26.4 and 23.1 respectively.

A listed 235mm of ground clearance is about standard for this kind of wagon but, as I’ve said before, it seems vulnerable in the underbody, side steps and its plastic mud guards. So the underbody may touch dirt, depending on how challenging the terrain is. 

Wading depth is listed as 800mm.

But, as always, with focused driving, you’ll have lots of fun and you'll minimise any superficial damage or scuff marks to the MU-X.

The MU-X has plenty of potential as a touring platform, but, if you’re planning to do any off-roading beyond well-maintained tracks, then get rid of its road-biased tyres and replace them with all-terrain tyres.

The showroom-standard tyres on this MU-X – 265/50R20 Bridgestone Dueler HTs – are okay, but not really up to scratch if tough 4WDing is what you’re keen to do. I’d prefer an 18-inch wheel and tyre package with decent all-terrains.

The MU-X has a full-sized underslung spare and in terms of packability, the MU-X X-Terrain has a listed payload of 605kg, GVM is 2800kg and GCM is 5900kg.

If you are considering using your MUX as a tow vehicle, it's handy to know that it can legally tow 750kg (unbraked) and 3500kg (braked), which is the standard for large four-wheel-drive wagons. 

Be aware though that, as with any other vehicles, once you're towing anywhere near the maximum weight, your payload is greatly reduced.

The best way to describe driving the X-Trail N-Trek is stress-free. It’s quiet, comfortable and composed with enough oomph for the cut and thrust of urban driving as well as the occasional foray onto the highway.

Maximum pulling power arrives at 3600rpm, which is higher than the small-capacity turbo SUVs the X-Trail most often competes with. But the pay off is crisp throttle response and you’re never found wanting for performance.

Drive goes to all four wheels via a ’shift-by-wire’ continuously variable transmission (CVT). By design CVTs cause the engine to hunt up and down the rev range, searching for the optimal gearing compromise between power and efficiency. But the CVT ’droning’ syndrome that characteristic can generate isn’t a noticeable factor in the X-Trail.

The strut front, multi-link rear suspension delivers smooth ride comfort helped in no small part by the standard 235/60x18 Bridgestone Potenza Sport A/S tyre’s cushy 60-series sidewall profile.

That rubber plays a part in the car’s modest road noise with wind noise on the freeway also low for a relatively upright SUV. The X-Trail also steers nicely with well-weighted assistance and good road feel.

We didn’t head off-road for this family review but the N-Trek’s variable AWD capability gives it the ability to confidently deal with loose or slippery unsealed surfaces.

An 11.1m turning circle is nice and tight, which, in concert with a reversing camera, 360-degree camera view and front and rear proximity sensors makes parking a straight-forward exercise.

Brakes are discs all around (ventilated at the front) and the pedal is agreeably progressive.

In fact, that kind of refinement is a hallmark of the way this car operates. Recently arrived competitors can be noticeably abrupt when it comes to brake, throttle and steering inputs.

Not so here. As mentioned in the Design section, these one per cent positive qualities lift the X-Trail above the norm.

The current Nissan X-Trail received a maximum five-star ANCAP assessment from testing in 2022 and it’s on the pace relative to others in the category.

Active (crash avoidance) tech is comprehensive including AEB with car, pedestrian and cyclist detection (operational from 5.0-130km/h for car detection), rear cross-traffic alert and rear AEB, adaptive cruise control, lane departure warning and lane keeping, an ‘Around View’ 360-degree camera view, blind-spot monitoring, tyre pressure monitoring and driver fatigue detection.

If an impact is unavoidable, there are seven airbags onboard, including side curtains (importantly, covering all three rows) and a front centre bag to minimise head clash injuries in a side-on crash.

There are three top tether points and two ISOFIX anchors for child seats/baby capsules across the second row seat. There are no top tether points on the third row.

The MU-X has a six-year/150,000km warranty and seven years of roadside assistance. That warranty is okay in terms of years, but unlimited kilometres would be welcome.

Service intervals are scheduled for every 12 months or 15,000km, whichever occurs soonest. 

Capped-price servicing covers the first five scheduled services for 24MY and later vehicle models (up to five years/75,000km, whichever occurs first) – at a cost of $469 for each service.

Nissan covers the X-Trail with a five-year, unlimited-kilometre warranty, which is the norm in the mainstream market. That said, the likes of GWM, Kia and MG are at seven years, unlimited-km with Mitsubishi offering conditional 10-year, 200,000km cover. Roadside Assist is included for five years.

The main service interval is 12 months/10,000km which is behind the more common 12 months/15,000km period, although pre-paid maintenance is available offering an approximate 10 per cent saving over (still capped-price) pay-as-you-go.

Pre-payment also means you can fold the cost of maintenance into the financing of the car (if you’re going that way).

For the X-Trail AWD, pre-paid servicing comes in at $2092 for five services within five years ($418.40 per workshop visit) compared to $2324 for individual capped-price services ($464.80 per visit). 

There’s that 10 per cent saving but it’s still relatively pricey when you consider the Toyota RAV4 Hybrid costs $260 per service.
