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.Â

Subaru Outback
The Subaru Outback has long been a fan favourite and this year sees a special-edition model grade ushered into the ranks.
The AWD Sport Touring XT has all of the bells and whistles of the top Touring XT grade but see's a distinct design difference, at least externally.
So it begs the question, do we need this special-edition model? We're family testing it this week to find out.

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.

Subaru Outback8.5/10
The Subaru Outback Sport Touring XT is what you get when you want a beefed-up station wagon masquerading as an SUV that can handle adventuring and haul the family around in comfort. The limited edition has all of the great features you'd expect from a top model and a reasonable price tag but its fuel thirst will turn some people off.
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.Â
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.Â

Subaru Outback
The Sport Touring XT model is only available in the exclusive Geyser Blue paintwork (you'll either love it or hate it), has green accents scattered across the body and sports sharply styled and dark 18-inch alloy wheels.
The rear gets black badging and a spoiler but the black plastic moulding that Subaru is well known for is well and truly present.
There are some small design differences between the limited edition and it's siblings but at the end of the day it looks like an Outback.
Head inside and you'll find a solid and well-built cabin. The dashboard features a flashy 11.6-inch tech screen but the instrument cluster is still mostly analogue with a small 4.2-inch screen.
There are heaps of buttons and dials to play with and you also get a proper gear-shifter. The design will make this a winner for folks who want a car to look like a car, with its controls where they expect them to be.
Overall, the cabin feels premium but isn't fussy.
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.Â
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.

Subaru Outback
The cabin of the Outback has always been practical but the premium features this grade comes with ensures proper comfort for all occupants.
Seat comfort is high with the powered front seats that have heat and ventilation functions but the driver benefits the most with the extendable lumbar- and under-thigh supports.
The rear row is almost as comfortable as the front where passengers feel secured by the padded side bolsters, while taller occupants will love the head and legroom on offer. The heat function for the outboards is appreciated and the directional air vents are easy to position.
The 213mm ground clearance means it's easy getting in and out of the model but access to the back row is a little annoying. The footwell lip sits high and catches unsuspecting feet but it's the doors that made my eight-year-old grumble this week because they're heavy to operate.
Storage up front isn't class-leading but you get a glovebox that fits a manual, a dual-opening middle console, two cupholders and drink bottle holders, as well as a sunglasses holder and small cubby in front of the gear-shifter (which is annoying to access).
Storage is much better in the rear with four map pockets, storage bins in each door, two cupholders and two drink bottle holders to choose from.
The boot has 522 litres of capacity available, which is plenty of room for a road trip or a big grocery haul and the level loading space makes it easy to slide things in and out. You get a proper full-size spare tyre, which is rare nowadays and the powered tailgate is always a handy feature.
Technology feels well rounded and the touchscreen multimedia system is responsive and easy to use. However, the portrait position makes the icons and text on the wireless Apple CarPlay look small and I may have made a few accidental calls this week because of it.
The satellite navigation is easy to use and there's also wireless Android Auto. Charging options are decent with each row getting a single USB-A and C port but the front misses out on a wireless charging pad.

Subaru Outback
There are usually five variants available for the Subaru Outback but the model on test for this review is a special edition that blends the qualities and features of the top Touring XT but with some exclusive design changes.
Did we need it? Probably not but Subaru has wisely kept the price increase to a minimum, so the AWD Sport Touring XT is $57,490 before on-road costs, just $500 dearer than the usual top grade.
Despite looking more like a station wagon, the Outback sits in the large SUV segment and when it comes to an 'apples to apple' comparison, there's nothing really to compare it to.
With that in mind, the Skoda Superb Sportline wagon costs $74,990 drive-away, and a more traditional SUV like the Volkswagen Tiguan Allspace 162TSI R-Line is priced from $60,590 MSRP.
The standard premium equipment for the Sport Touring XT model includes Nappa leather upholstery, eight-way powered front seats with the driver enjoying additional lumbar and under-thigh support, as well as two-position memory function.
Also included are heating and ventilation functions for the front seats, heat function for the rear outboard seats, a heated steering wheel and sunroof with manual blind.
Technology is well-rounded with an 11.6-inch touchscreen multimedia system with satellite navigation, dual climate control, wireless Apple CarPlay and Android Auto, digital radio, AM/FM radio, two USB-A ports, two USB-C ports, two 12-volt sockets, and a nine-speaker Harman Kardon sound system.
Practical features include dusk-sensing LED headlights, rain-sensing windscreen wipers, keyless entry/ start, a full-size spare tyre and hands-free powered tailgate.
The limited-edition model is well-specified and while it lacks the extra two-seats that its rivals have, it still offers solid 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.Â
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.

Subaru Outback
The Sport Touring XT gets a 2.4L four-cylinder turbo-petrol boxer engine that produces a hefty 183kW of power and 350Nm of torque.
The re-tuned continuously variable transmission (CVT) system feels like it is changing gears but it's smooth and punctual, no matter the speed.
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.Â
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.Â
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.

Subaru Outback
Unfortunately, the turbo-petrol engine is thirsty and the official combined fuel cycle figure is 9.0L/100km.
With its 63L fuel tank, you have a theoretical driving range of up to 700km, which is best-case scenario but expect less range if you’re a city dweller.
After doing a mix of open road and city driving this week, my real-world usage came out at 9.3L, which is better than I expected.
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).Â
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).

Subaru Outback
The Sport Touring XT model is nice to drive. The best word to describe the on-road experience is ‘smooth’.
Power delivery is prompt and getting up to speed feels effortless. It's a great open roader but also feels spritely in the city.
The ride comfort is excellent and it’s only when you hit the highway that the wind noise starts to creep up, otherwise, the cabin is quiet and you can chat with back passengers without raising your voice.
The higher ride doesn’t translate to a bumpy suspension and while you’re aware of the road, you’re never bothered by it.
The steering is on the right side of firm for it to feel agile and competent no matter what you’re throwing at it. Visibility is also pretty good but the headrests in the back seat, when up, can hinder your rear-view vision.
The Outback sits at 4870mm long and 1875mm wide, so it fills out a car space but the higher ground clearance means you’re not worried about scraping on ramps and it’s relatively easy to park.
However, it feels cheeky to not have a 360-degree view camera system at this grade level. The reversing camera it comes with is sufficient, but you miss out on front parking sensors.
Safety
Isuzu MU-X
The D-Max and the MU-X both have the maximum five-star ANCAP safety rating.
As standard they have AEB, eight airbags - dual front, curtain, side, driver's knee and far side (front centre) - and a comprehensive suite of driver-assist tech including 'Forward Collision Warning', 'Adaptive Cruise Control', 'Lane Departure Warning', a tyre-pressure monitoring system and a raft of other driver-assist tech.

The Outback has a maximum five-star ANCAP safety rating from testing done in 2021 and features eight airbags which includes a front centre airbag.
It also scored highly across its individual assessment scores with ANCAP. It got 88 per cent for adult protection, 91 per cent for child protection, 84 per cent for vulnerable road users, and 96 per cent for its safety assist systems.
Standard safety equipment includes blind-spot monitoring, tyre pressure monitoring, LED daytime running lights, rear and forward collision warning, rear cross-traffic alert, lane departure alert, lane keeping aid, emergency lane keeping aid, emergency autonomous steering, lead vehicle start alert, traffic sign recognition, adaptive cruise control, reversing camera and front parking sensors.
The driver monitoring system has been improved from previous models and while still sensitive, it no longer chimes at you all the time, which is a welcomed change.
The Outback has two ISOFIX child seat mounts and three top-tether anchor points. The rear seat is wide enough to accommodate three child seats if they're not too large.
The auto emergency braking (AEB) has car, pedestrian, cyclist and back-over detection and is operational from 1.0 to 160km/h but it's usual to see this system operate from 5.0km/h, which is excellent.
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.
