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?

Jeep Grand Cherokee
Jeep Australia's first plug-in hybrid, the Grand Cherokee 4xe, has arrived at a time when the company’s sales figures need a decent shot in the arm.
Though it’s seemingly spearheading a large and extra-large SUV hybrid push into the Aussie market, with the likes of a Toyota LandCruiser 300 Series hybrid on its way, the marque’s debut PHEV is only available here in the range-topping Summit Reserve spec, and only as a five-seater.
So, does the 4xe have enough of a jump on any large SUV hybrid rivals – including a rumoured but postponed Ford Everest hybrid – and is it enough to give the brand a much-needed boost?

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.

Jeep Grand Cherokee7/10
A wise man* once said "Being first can sometimes feel like being wrong" and perhaps that's how it is with the 4xe, but at least Jeep Australia is giving the large SUV hybrid realm a good ol' try.
* Former CarsGuide Big Kohuna, Glen Knowles.
The company's first plug-in hybrid, the Grand Cherokee 4xe, is not perfect by anyone's standards, however, it is a definite move in the right direction.
It's a quiet and refined drive, it retains the brand's renowned 4WD capability, and even its hefty price-tag likely won't dissuade Jeep loyalists from giving it a go.
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.

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.

Jeep Grand Cherokee
The Jeep Grand Cherokee Summit Reserve 4xe PHEV retains the regular model’s level of functionality but adds a reasonably classy touch to everything.
All seats offer adequate comfort, support and room.
There are plenty of storage spaces, cupholders etc, and charging points - two USB-A and two USB-C plus a 12V socket in the front and two USB-A and two USB-C plus a 230V point in the back.
Controls are generally easy enough to locate and operate although some buttons are positioned in awkward places – including drive-mode buttons under the steering wheel – and it sometimes takes a few finger-stabs at the multimedia touchscreen to get to where you want to go in the operating system.
In terms of packability, the rear cargo area has a listed 1067 litres of space, and, with the second row folded and out of the way, that space opens up to 2004 litres.

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.

Jeep Grand Cherokee
The Jeep Grand Cherokee Summit Reserve 4xe PHEV has a 2.0-litre four-cylinder turbo-charged petrol engine, two electric motors (one on each axle) and a 17.3kWh battery.
Combined engine and electric outputs for power and torque are 280kW and 637Nm, respectively. The 4xe has it over any of its stablemates equipped with the 3.6-litre Pentastar V6 petrol engine because that yields 210kW and 344Nm.
The 4xe has an eight-speed automatic torque-converter transmission and regenerative braking.
Drive modes include 'Hybrid' (with combined engine and electric motor providing “maximum instant torque and impressive acceleration”, according to Jeep), 'Electric' (“zero emissions”) and 'eSave' (aims to save battery power).
There are a few options available when it comes time to charge the 4xe.
The 4xe vehicle has a Mode 2 charging cable so you can charge it at home in less than 10 hours, according to Jeep.
With a full charge, the 4xe has a claimed driving range, on electric charge alone, of 52km.
Jeep reckons a Mode 3 (wall box) single-phase electric vehicle charger will fully charge the 4xe in less than three hours.
If out and about and looking for a charge, a 4xe driver can use the onboard 'UConnect' system to locate an appropriate public charging station.
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.

As mentioned, the 4xe has a listed electric-only driving range of 52km.
On our official test day, we drove just under 50km on a full electric charge and then the rest of the trip was courtesy of the good ol’ petrol engine.
Jeep's official figure for the combined cycle is just 3.2L/100km, but that's predicated on keeping the hybrid battery charged at all times. On fuel-only we recorded 11.6L/100km.
The 4xe has a 72-litre fuel tank (you need 95RON premium to fill it), so going by that on-test fuel-consumption figure, you could reasonably expect to get a driving range of about 620km out of a full tank.
Add an approximate electric range of about 50km on a full charge to that figure and you have a total estimated driving range of 670km.
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).

Jeep Grand Cherokee
We’re all time-poor, right? So, why should I take up your time and rattle on about the 4xe for a thousand words when I can get the essence of it across to you, the reader, in a few sentences? Call me, Mr Thoughtful.
This is generally a big, quiet and refined, easy-steering large SUV, but it feels bulky at times and tends to be quite fussy on irregular surfaces, exhibiting a jittery ride on even brief sections of light corrugations on dirt tracks.
The 4xe’s PHEV set-up is smooth and highly responsive on-road and you can switch between the aforementioned drive modes to suit the circumstance.
Driving range on electric only is listed as 52km. I only recorded a total distance of just under 50km, and it’s a very quiet and smooth drive while relying on electric power.
It regenerates power rather quickly down big hills and via braking, but we’d exhausted all electric charge by the time we’d reached our 4WD test track.
As expected, this Grand Cherokee tackled every off-road challenge without any strife.
The air suspension, set to full off-road height, is a bonus.
Our 4WD test track consists of difficult set-pieces, including one small steep rocky hill that I’ve seen heavily modified vehicles struggle to conquer and, to the Jeep’s credit, it climbed the incline, no sweat.
The 4xe’s efforts were only ever hampered by its 'all-season' Continental CrossContact tyres (275/45R21) which are much better suited to blacktop driving and the fact the 4xe costs upwards of $129,950 and I didn’t want to risk any damage to it.
The 4xe has a listed wading depth of 610mm but our test track was dry so I never had the chance to do any water crossings.
The Grand Cherokee has a solid enough rep as a towing vehicle but, take note, the 4xe is rated to tow 2722kg.
