Summary
Isuzu MU-X
It’s an age-old debate: Which is the best vehicle for 4WDing, a wagon or a ute?
In order to draw closer to a definitive answer, we’ve pitted two of Isuzu’s well-equipped and very popular top-shelf 3.0-litre 4WDs – the seven-seat MU-X in LS-T spec and the five-seat D-Max X-Terrain – against each other to find out.
On paper, this seems like it should be a close contest.

The D-Max has recently been given a mid-life facelift, replete with revised exterior styling as well as useful upgrades to its multimedia system, while the MU-X has received a more modest model-year update.
While the MU-X now has an entry-level 1.9-litre turbo-diesel four-cylinder engine option, this test is focussed on the 3.0-litre version.
They are both well-equipped and have plenty to like, but which is the right one for you?

LDV D90
It’s pretty hard to miss the LDV D90.
Mainly because it is gigantic; it's one of the biggest SUVs you can buy. In fact, I’d say what’s drawn you to this review is maybe you’ve seen one of these behemoths trucking past, and you’re wondering what the LDV badge is all about and how this relatively unknown SUV stands up against popular rivals and other notable newcomers.
To get one confusing thing out of the way, LDV once stood for Leyland DAF Vans, a now-defunct British company which has been brought back to life by none other than China’s SAIC Motor – yes, the same one which also resurrected MG.
So, is this MG big brother worth looking into? We took the recently released diesel version of the D90 on test for a week to seek some answers…

Verdict
Isuzu MU-X/10
The D-Max and the MU-X are two impressive 4WDs and both of them have plenty of appeal as daily drivers and touring platforms, but for slightly different reasons.
Both are evenly matched in terms of 4WD capability and have plenty to like in terms of driver-assist tech, standard features, and all-round driveability, but each has definite advantages and some minor trade-offs.
Which one is best for you? Well, that really depends on your lifestyle and your needs.
I like the seven-seat MU-X. It has plenty of appeal, but, for my money, I’d go for the D-Max. I use my vehicle for carrying loads – kayaks, surfboards, camping gear, and sometimes even building materials, furniture, rocks and rubbish – and a ute gives me extra versatility in terms of carrying onboard loads.

LDV D907.1/10
Looking for a cheap, powerful diesel SUV with huge cabin space and a humane third row for adults? The D90 is a really sound offering, especially considering the price of entry for this top-spec diesel which should resonate with Aussies a bit better than the petrol version.
It has plenty of issues that could be ironed out, but they’re all so small and not sale-breaking it’s almost annoying how much better the D90 could be with just a little work. Rivals should be looking over their shoulder for what comes next.
Design
Isuzu MU-X
The D-Max and MU-X have never been particularly boring or indeed exciting in the looks department, which is a bonus in an age where inoffensive is sales gold.
But after its latest refresh treatment, the D-Max now has a bigger grille, new headlights, three-tier LED tail-lights, and redesigned wheels over the previous version.
Distinctive ‘X’ branding is included here and there – inside and out – and that adds a low-key class to the X-Terrain.
The MU-X is, well, the MU-X. Which is to say it doesn’t drum up any strong feelings – love or hate – either way.
For specs nerds, of which I’m one, the D-Max X-Terrain is 5310mm long (with a 3125mm wheelbase), 1880mm wide, 1810mm high and has a listed kerb weight of 2170kg. It has a wheel track of 1570mm and a 12.5m turning circle.
The MU-X LS-T is 4850mm long (with a 2855mm wheelbase), 1880mm wide, 1825mm high and has a listed kerb weight of 2180kg. It has a wheel track of 1570mm and an 11.4m turning circle.

LDV D906/10
Some colleagues I’ve spoken to like the way the D90 looks. To me, it looks like someone gene-spliced a Hyundai Tucson with a SsangYong Rexton in a lab, then grew it in a stew of peptides and this was the result.
What can’t really be communicated in images is how truly massive the D90 is. At over five metres long, two metres wide and almost two metres tall, the D90 is certifiably huge. Given that’s the case then, it’s admittedly almost admirable that only the side profile makes this thing look a little goofy.
I think LDV has done a pretty good job on the front, and the rear is simple but well resolved for a vehicle that rides on a ladder chassis (just take a look at the Pajero Sport for how ladder-chassis rear designs can get… controversial…).
The wheels, garnishes, and LED headlights are all tastefully applied. It’s not ugly… just confronting… size-wise.
Inside shares some familiar characteristics with sister-brand MG. Look from a distance and it’s all quite nice, get in too close and you’ll see where the corners have been cut.
The first thing I don’t like about the interior is the materials. Apart from the wheel they are all pretty cheap and nasty. It’s a sea of hollow plastics and mixed trims. The faux-wood pattern, which is clearly just a print on a plastic resin is particularly gnarly. Reminds me of some Japanese cars from 20 years ago. It might work for the Chinese audience, but that’s not where the market is in Australia.
On the other hand, you could say “well, what do you expect at this price?” and that is true. Everything is here and works, just don’t expect the D90 to be playing alongside the established players when it comes to fit, finish, or material quality.
The huge screen works to finish the dash, but that darned software is so ugly you’ll wish it didn’t. At least all the major touch-points are ergonomically accessible.
Practicality
Isuzu MU-X
Not a lot separates these two vehicles in terms of functionality or comfort because they share essentially the same interior with only a few differences.
The X-Terrain does, however, pip the LS-T overall with a slightly more premium look and feel to the cabin. Subtle touches such as red stitching in the cabin trim enhance the interior’s quiet charm.
Both cabins have a pleasant, familiar feel about them and are easy spaces in which to swiftly get comfortable and to quickly figure out where all controls are. And it’s easy to use those controls.
The X-Terrain has a black leather-accented trim, but there are plenty of durable plastic surfaces to cope with the messiness of real life.
The MU-X also has a leather-accented trim, but the same, practical plastic surfaces are present.
Charging options are numerous throughout the cabins of both vehicles – a mix of USB-A, USB-C and 12V up front, and USB-A for the second row.
Storage places (in both vehicles) 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 also cupholders either side of the third row in the MU-X for passengers riding back there.
There’s one seemingly minor but noticeable difference between the operation of the 9.0-inch multimedia touchscreen systems.
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), while those functions and others are activated/adjusted via on-screen buttons in the D-Max. No big deal, but you may prefer one of those approaches.
The load spaces on offer are obviously also a big point of difference in these vehicles.
The D-Max has a tub and it is shielded by a manually-operated roller-shutter cover that can be partially or fully opened or closed.
The tub is 1495mm long, 1530mm wide (1122mm between the wheel arches) and 490mm deep.
It is a double-walled tub, with an under-rail tub liner, two cargo tie-down points and it has tailgate assist.
The roller cover offers at least some degree of security from thieves, and protection from the elements (rain, mud, snow etc), but the drum (in which the cover is stored when it is rolled open) does impact the packability of the load space.
Another option for D-Max owners is to get an Isuzu or aftermarket canopy, although that impacts the versatility of the load space because once it’s an enclosed area it makes it a bit more difficult to carry long and/or large loads in the tub.
The MU-X has the advantage here in terms of security and protection from the elements because its load space is fully enclosed from the factory.
The MU-X’s cargo area is 311 litres with all three rows in use; 1119 litres with the third row flat; and it’s 2138 litres with the second and third rows folded.
The rear cargo area has a cargo cover (so any potential crooks who look through your windows are unable to see your valuables), tie-down points and a 12V power outlet. There is a storage space under the rear cargo area floor and a tool storage space inside the driver’s side rear cargo wall.

LDV D909/10
The D90 is as massive on the inside as it is on the outside. I’m talking better space than a minivan, and nothing says that more than the humane third row. At 182cm tall, I not only fit in the rearmost two seats, but I can do so in as much comfort as any other row. It’s staggering. There’s actual airspace for my knees and head back there.
The second row is massive and on rails too, so you can extend the amount of room available to third-rowers – and there’s so much room in the second row, you’ll have space even with the seats moved forward.
My only criticism here is that the giant rear door is far enough forward to make clambering into the third row a little tricky. Once you’re there though there are really no complaints.
The boot is even usable with the third row deployed, with a claimed 343L of space. That should be hatchback-sized, but the measurement is a little deceptive as the space is tall but shallow, meaning it will only allow you to place smaller bags (a few, if you can stack them) with the remaining space.
The boot is otherwise cavernous with a wild 1350L available with the third row stowed flat, or 2382L with the second row stowed. In this configuration, with the front passenger seat slid forward to its furthest position, I was even able to get a 2.4-metre-long benchtop in the back. Truly impressive.
Without buying an actual commercial van then, this could be the cheapest way into such room, especially in a 4x4 bi-turbo diesel SUV. No arguing with that.
Second-row occupants get their own climate control module, USB ports and even a full-sized household power outlet, with more legroom than you could possibly need. My only complaint was that the seat trim seemed a little flat and cheap.
Front occupants get large cupholders in the centre console, a deep armrest box (with no connectivity in it, just a randomly placed DPF cycle switch), pockets in the doors, and an awkward binnacle under the climate controls that houses the single available USB port. My phone didn’t fit in there.
No complaints about leg and headroom in the front either, though, with plenty of adjustability to boot. The driver’s seat offers a commanding view of the road, although it can be a little unsettling to be so far off the ground in corners… more on that in the driving section.

LDV D908/10
On paper, the seven-seat D90 is immediately quite appealing. At $47,990, it is literally a lot of car for the money. This latest iteration, the bi-turbo diesel, is only available in Executive trim at this price, but you can pinch pennies further by choosing one of the lesser petrol turbo variants.
Regardless, and much like its MG sister brand, LDV is good at making sure that essential spec boxes are ticked.
This includes screens galore as is popular in the Chinese market, including a massive 12-inch multimedia screen and 8.0-inch digital dash.
A screen is only as good as the software that runs on it though, and let me tell you, the D90’s software is not good. A quick flick through the weirdly small menu reveals barebones functionality, terrible resolution and response time, as well as possibly the worst execution of Apple CarPlay I’ve ever seen.
I mean, it doesn’t even use all of that screen real estate! Not only that, but in a recent overhaul to CarPlay, Apple released software to utilise wider displays – so the car’s own software must simply be incapable of supporting it. Inputs also proved laggy, and I had to repeat myself on multiple occasions to get any use out of Siri. Unlike every other car I’ve used, the software in the D90 wouldn’t return to the radio after you hang up or stop talking to Siri. Frustrating.
I’d rather have a far smaller display that actually worked well. The semi-digital dash was functional, although barely did anything that a small dot-matrix display isn’t capable of and had one screen which for my entire week said ‘loading’. I’m still not sure what it was meant to do…
At least it supports Apple CarPlay at all, which is more than could have been said for segment hero, the Toyota LandCruiser.
The D90 does tick some necessary items that are quite good. LED headlights are standard, as are leather seats with eight-way power adjust for the driver, a heated multi-function steering wheel, 19-inch alloy wheels (which still somehow look small on this huge thing), three-zone climate control, eight-speaker audio system, electric tailgate, keyless entry with push-start ignition, a reversing camera, front and rear parking sensors, tyre-pressure monitoring, as well as a fairly substantial safety suite which we’ll explore later in this review.
Great on paper then, the bi-turbo diesel engine is a boon, as is the fact that the D90 rides on a ladder chassis with an electronically-controlled low-range terrain mode for the transmission, too.
You’d expect to pay more – even from Korean and Japanese rivals for this much specification. No matter which way you cut it, the D90 is good value.
Under the bonnet
Isuzu MU-X
Both of these vehicles have a 3.0-litre, four-cylinder, turbo-diesel engine, producing 140kW at 3600rpm and 450Nm from 1600 to 2600rpm, matched to a six-speed auto.
This engine and auto combination forms part of a proven powertrain and while these two vehicles may be a bit sluggish in acceleration terms and may not be the most dynamic vehicles to drive, the D-Max and the MU-X have a real tractability about them that negates any other flaws.
They both have part-time 4WD, with high- and low-range. Driver-assist tech such as 'Rough Terrain' mode has been tweaked with the aim of making Isuzu 4WDs perform off-road even better than before.

LDV D907/10
The D90 was initially offered in Australia with a 2.0-litre turbo petrol four-cylinder, but this 2.0-litre bi-turbo diesel makes much more sense, both for towing and long-distance touring.
It’s a four-cylinder offering a healthy 160kW/480Nm. You’ll note that’s pretty close to Ford’s similar 2.0-litre bi-turbo diesel, which is currently offered in the Everest…
The diesel also gets its own transmission, an eight-speed torque converter automatic with computer-controlled ‘Terrain Selection 4WD’.
This gives the D90 diesel a max towing capacity of 3100kg braked (or 750kg unbraked) with a max payload of 730kg.
Efficiency
Isuzu MU-X
Official fuel consumption for this D-Max is 8.0L/100km on a combined cycle which rises to 8.3L/100km for this MU-X is.
Actual fuel consumption on this test, from pump to pump, was 9.8L/100km for the D-Max and 10.2L/100km for the MU-X.
The D-Max has a 76-litre fuel tank. So, going by those fuel consumption figures, you should be able to get a driving range of about 775km from a full tank.
The MU-X has an 80-litre fuel tank and using our real-world consumption figure you should be able to get a driving range of about 784km.

The D90 diesel is said to consume 9.1L/100km of diesel on the combined cycle, but ours didn’t score near that with a figure of 12.9L/100km after a week of what I’d consider “combined” testing.
The D90 a big unit, so that number doesn’t seem outrageous, it’s just nowhere near the claim… All D90s have 75-litre fuel tanks.
Driving
Isuzu MU-X
These two are evenly matched in terms of drivability and off-road capability.
We spent the lion’s share of our test time off-road but these two vehicles are fine on sealed surfaces; easy to drive (albeit a bit sluggish) and suitably refined (albeit a bit noisy).
Both can feel a tad agricultural to steer about at times but, as I said before, that’s okay and part of the Isuzu charm.
But beyond satisfying any daily-driving requirements these vehicles are impressive 4WDs.
From the engine-and-auto pairing, through to driver-assist tech, physical dimensions and simply general all-round suitability, these two are naturals in most off-road environments.
The D-Max and MU-X have plenty of low- and mid-range torque but both also have quite firm suspension over gravel and dirt tracks at speed, and are rather noisy. Although, if you’ve spent any time in a diesel 4WD the tractable engine’s subdued clatter won’t bother you at all.
But there are some differences between the two in terms of their overall performance off-road.
The D-Max has had, through recent development phases, a recalibrated off-road traction control system that's been improved to be more precise and effective through challenging terrain.
But the D-Max now benefits from the introduction of what Isuzu calls Rough Terrain mode, which operates like a boosted off-road traction control, claimed to kick into action at a point of less wheel-spin than a standard off-road traction control system, transferring torque to the wheels that have the most traction, sooner rather than later. Rough Terrain mode debuted in the MU-X in 2021.
This is not a magic pill by itself, but it’s another handy addition to the D-Max’s already-substantial off-road toolbox that also includes a rear diff-lock.
The D-Max has a greater listed ground clearance (240mm) than the MU-X (235mm) but both vehicles have the same wading depth (800mm).
The D-Max is somewhat hamstrung by its longer wheelbase (3125mm compared to the MU-X’s 2855mm wheelbase) and it has shallower approach and departure angles (27.3 and 19.0, respectively) than the MU-X (29.2 and 26.4), but its ramp-over angle is greater (not by much) at 23.8 degrees vs 23.1.
The MU-X is more nimble than the D-Max on technically challenging 4WD tracks, with its shorter wheelbase and shorter overall body length (4850mm vs the D-Max’s 5310mm). Its turning circle is 11.4m compared to the D-Max’s 12.5m.
Those factors don’t take anything away from the D-Max’s efficacy off-road, it simply means this ute needs to be driven with more careful consideration than the wagon.
Often, the size and type of standard tyres on a top-shelf 4WD straight out of a showroom are not ideal for 4WDing and should be replaced if off-roading is on the new owner’s agenda anytime soon.
However, the tyres on this D-Max and MU-X – 265/60R18 Bridgestone Dueler 684II HT (Highway-Terrain) tyres on the D-Max and 265/50R20 Bridgestone Dueler HTs on the MU-X – are okay, but not really up to scratch if tough 4WDing is what you’ll be doing.
The D-Max’s 18-inch wheel-and-tyre package is at least a more 4WDing-friendly sizing than the MU-X’s 20-inch combo.
Replace the HT tyres with a decent set of all-terrain tyres and maybe consider getting rid of the standard suspension while you’re at it and switch in an aftermarket lift kit, just for the hell of it.
Both vehicles have full-sized spares and in terms of packability, the D-Max has a listed payload of 930kg, while payload in the MU-X is 620kg.
Both vehicles can legally tow 750kg (unbraked trailer) and 3500kg (braked).

LDV D906/10
The D90 is easier to drive than it looks… to a degree…
It lacks some polish of its more established rivals, which results in a drive experience that isn’t bad, but occasionally frustrating.
The ride somehow manages to be soft and harsh at the same time. It undulates over larger bumps, while transmitting the worst parts of smaller, sharper ones to the cabin. It speaks to a lack of calibration between the suspension and dampers.
That having been said, the D90 masks its ladder chassis underpinnings well, with little of that typical body-on-frame jiggle that some rivals still struggle with.
The drivetrain is good, but a little unruly. As you’d imagine from the figures, there’s more than enough power on tap, but the transmission tends to have a mind of its own.
It will occasionally lurch between gears, pick the wrong gear, and off-the-line will sometimes be delayed before shunting the D90’s bulk forward with a sudden mountain of torque. It doesn’t sound particularly good either, with the diesel surging through the rev range with industrial crudeness.
By the time the D90 has reached cruising speed though, there’s really not much to complain about, with the D90 milling along with plenty of power in reserve for overtaking. The view of the road is commanding, but you really feel the D90’s high centre of gravity in the corners and under heavy braking. The physics of such a large object are undeniable.
I have to say, LDV has done a fantastic job of the D90’s steering, with a quick, light feel that betrays the SUV’s size. It manages to stray on the right side of lightness though, not being so disconnected that you lose a feeling of where the wheels are pointing. No mean feat in something this shape.
Overall then, the D90 isn’t bad to drive and has some genuinely great characteristics, it just also has a litany of small issues that get in the way of it being truly competitive with segment leaders.
Safety
Isuzu MU-X
The D-Max and the MU-X both have the maximum five-star ANCAP safety rating.

The LDV D90 carries a maximum five-star ANCAP safety rating as of 2017, and has a fairly comprehensive active safety suite.
Included on the diesel is auto emergency braking (AEB) with front collision warning, lane-departure warning, blind-spot monitoring, driver-attention alert, traffic-sign recognition, and adaptive cruise control.
Not bad for the price, and nice that there’s nothing optional. Expected items include electronic traction, stability, and brake controls, as well as six airbags.
The curtain airbags do extend to the third row, and there’s the bonus of a reversing camera and a tyre-pressure-monitoring system.
There is a full-size steel spare under the boot floor, and the D90 also gets dual ISOFIX and three top-tether child-seat mounting points.
Ownership
Isuzu MU-X
The D-Max and the MU-X have a six-year/150,000km warranty and seven years of roadside assistance. That warranty is okay in terms of years, but unlimited km would be a welcome sweetener.
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 models (up to five years/75,000km - whichever occurs first) at a flat price of $449 for each service.

LDV covers the D90 with a five-year/130,000km warranty, which is not bad… but falls behind sister brand MG, which offers seven years/unlimited kilometres. At the very least it would be nice to have the unlimited kilometre promise.
Roadside assist is included for the duration of that warranty, but there’s no capped price servicing offered through LDV. The brand gave us indicative pricing of $513.74, $667.15, and $652.64 for the first three annual services. An initial six-monthly 5000km checkup is free.
All D90s need to be serviced once every 12 months or 15,000km, whichever occurs first.
