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?

The Land Rover Discovery Sport is the sort of Land Rover you consider if you're not that serious about going off-road but still want something capable, but you don't want a car as large as it's Range Rover cousins.

Bonus points, the P300e mid-spec model I'm testing this week is a plug-in hybrid. So, you get the best of all worlds - capability, decent size and economy.

The new powertrain pits it against the Lexus NX450+, Volvo XC60, Audi Q5 and even the BMW X3 but while the P300e is great on paper, how does it stack-up in real life?

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.

Land Rover Discovery Sport7.6/10

The Land Rover Discovery Sport P300e has a beautiful and practical cabin space. The powertrain didn't always convince me on the road but it does offer decent economy, if you charge it often.

The media system left a lot to be desired and having to pay around $15K extra for all of the customisations means it's not as affordable as what it initially seems. Still, if you’re looking for a plug-in hybrid with a great cabin and on-road looks, this is a good option.

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.

The updated Disco Sport gets new underpinnings which are shared with the Range Rover Evoque.

The body has seen a minor facelift but honestly, it’s so slight only die-hard fans will notice anything different. Overall, it still has the styling that people know and love.

It’s once you head inside that the facelift becomes far more apparent. Gone is the more traditional looking e-shifter and in its place is a rather nubby-looking one.

The dashboard looks more streamlined and features wider padded accents and in our test model, we have the Oyster and Black upholstery which does make it look quite luxurious. There are a few too many blank spaces for me personally but it looks slick.

Accentuating the dashboard is a floating-effect multimedia system and a large digital instrument cluster – both of which look great but there are no other control buttons or dials. I’m not a fan of the fact that you’re 100 per cent reliant on the tech screens and I'll explain why in the Practicality section.

The optioned panoramic roof makes the cabin feel airy and it's cool that it has a memory function – it will close when you turn off the car but reopen upon starting again.

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.

Land Rover Discovery Sport

With it's 4597mm length, 2173mm width and 1727mm height, the Discovery Sport is technically classed as a medium SUV but the cabin space is much larger than it has any right to be.

Both rows have ample head- and legroom for both my 168cm (5ft6') height and those much taller. When you have a co-pilot, you’re also not jostling for elbow room and it’s easy to slide in and out of because of the 212mm ground clearance.

The amenities up front are good with the update seeing more decent sized individual storage options.

There are two cubbies in the centre console as well as two cupholders and a medium-sized middle console. The glove box can hold more than a manual and the storage bins with their single drink bottle holders are also larger than before.

The powered front seats are comfortable and the optioned heat functions are most welcome on the cooler days we've been having lately.

The back seats also have superior padding comfort but you sit on top of, rather than in, them which is typical of an SUV.

The amenities and storage are what you would expect for the grade level with a fold-down armrest with two cup holders and small storage cubby, directional air vents, reading lights, map pockets and small storage bin in each door.

There is also an accessory hole to attach device holders on the backs of the front seats - perfect for hooking up a screen for little ones on a long journey.

The P300e loses points on its practicality with the multimedia system. You eventually get used to using it while on the go, even though the lack of buttons/dials means more time is spent with your eyes on the screen.

That's when the screen turns on. The display has cut out a few times this week and the wireless connectivity for Bluetooth and the connection for Apple CarPlay (wireless or wired) drops out a lot.

The P300e I'm driving is brand-spanking-new, so it may just be a case of something that needs calibrating but for a lot of the Land Rovers I've sampled in the past, the media system seems to be the area with the biggest teething issues.

That being said, the built-in satellite navigation is top-notch and easy to use. The directions also get displayed on the instrument cluster and optioned HUD.

The charging options are excellent with the front row getting three USB-C ports and a large wireless charging pad. The rear gets two USB-A ports and two USB-C ports plus a 12-volt socket and the boot also has a 12-volt socket. Totally spoiled for choice.

The boot is a great size at 897L with all seats in use and that jumps up to 1749L when the rear seats are folded flat. The rear row also has a 40/20/40 split, which opens up storage opens.

There is a temporary spare tyre housed underneath the flat floor and a powered tailgate comes standard in this model, which I always like.

Land Rover Discovery Sport

The Discovery Sport is offered in four grades and the model on test in this review is the plug-in hybrid mid-level P300e.

The P300e is priced from $102,125 before on road costs but the addition of the plug-in hybrid powertrain means that it is actually $8855 more expensive than the flagship HSE.

In terms of its rivals, the P300e sits towards the middle of the line-up with the Volvo XC60 Recharge Plus PHEV coming in as the most affordable at $92,990 before on-road costs, then the Lexus NX450+ PHEV at $93,498. Sitting at the more expensive is the Audi Q5 55 TFSIe at $106,600 and then the BMW X3 xDrive30e M Sport PHEV at $111,800.

However, our test model does have a few optioned extras which ups the price tag and its position in the pack.

Those options include:

- A Technology Pack for $4700 which adds a digital rearview mirror, head-up display, and a 360-degree camera system with wade sensors.

- A fixed panoramic roof for $3040.

- Upgraded Meridian Surround Sound System for $2220.

- Upgraded 20-inch alloy wheels for $2080.

- Heated front seats for $860.

- Home charging cable for $520.

- Titanium mesh trim for $420.

All of that brings the grand total to $117,290, before on roads. Which is no small lump of change for what is essentially just a baby Land Rover.

Standard luxury and practical features include powered front seats with a three-position memory function for the driver, synthetic leather upholstery, keyless entry, push-button start, powered tailgate, temporary spare-tyre, and dual-zone climate control.

Technology includes an 11.4-inch touchscreen multimedia system, 12.3-inch digital instrument cluster, Android Auto, wireless charging pad, Bluetooth connectivity, and DAB+ Digital Radio.

The update also sees wireless connectivity for Apple CarPlay, an Amazon Alexa app, as well as new USB-C ports, as opposed to USB-A ports from the previous model.

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.

Land Rover Discovery Sport

The Discovery Sport P300e has a 1.5-litre, three-cylinder plug-in hybrid turbo-petrol engine with an eight-speed auto transmission and is an all-wheel drive.

The engine produces a combined power output of 227kW and 540Nm of torque. On paper, it’s punchy and can do a 0-100km/h sprint in 6.6 seconds but in practice, it’s not always great at using that power.

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 official combined fuel cycle consumption figure is 2.1L/100km and my real-world usage sits a 4.8L/100km after doing some open-roading and lots of urban trips this week. For an SUV of this size and with it's power, that's pretty darn good.

The trick is to regularly charge it for maximum fuel economy gains and that's not always practical.

Officially, you get up to 66km of pure electric range in this but expect closer to 47km in the real world. 

The P300e has a Type 2 CCS charging port which means you can hook this up to a fast charger. On a 50kW system, you can go from 0-80 per cent in as little as 30 minutes but on a 7kW system, going from 0-100 per cent jumps up to to two hours and 12 minutes.

Expect to leave it on charge overnight on a standard domestic socket.

The driving range based on the official combined fuel cycle is obscene, and I can't see it happening in real life - so, based on my fuel economy figure and the 58L fuel tank, expect a theoretical driving range of up to 1208km.

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).

Land Rover Discovery Sport

The Discovery Sport P300e has the goods on paper when it comes to power and it does... once you're up to speed. That's when you can punch it and feel confident at overtaking or keeping your speed consistent on hills.

It's when you're accelerating from a full-stop that it becomes a bit lacklustre as there's serious lag between accelerating and actually moving forward. Accept that you will have to accommodate for this inaction whenever you are joining or crossing traffic from a standstill.

Besides this little hiccup in the power delivery, handling on the whole is good.

The Disco Sport is easy to manoeuvre and you don’t feel like you’re driving something big, despite the ample cabin space. It also handles itself well in corners without too much roll.

The switch between the electric and petrol components isn’t always the smoothest but when it’s in its electric mode it’s blissfully quiet. The cabin feels refined too because you don’t get a lot of external noise in the cabin at all.

The wide windows and higher ride means visibility is great and the optioned digital rearview mirror adds another viewpoint if the back window isn’t clear.

The Disco Sport proves to be nimble and easy to park with the optioned and clear 360-degree camera system, and the sensors at the front and rear are sensitive.

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.

Land Rover Discovery Sport

The Discovery Sport plug-in hybrid variant is not covered by its siblings' five-star ANCAP safety rating from 2022, so the P300e is unrated but features some good safety gear.

Standard items include AEB, blind spot monitoring, driver attention alert, tyre pressure monitoring, rear collision warning, forward collision warning, rear cross-traffic alert, lane keeping aid, traffic sign recognition, intelligent seatbelt warning, and adaptive cruise control.

The traffic sign recognition tech is dreadfully intrusive, which impacts the driving enjoyment. I turn the warning sound alerts off each time I hop in as it's like a small child is hitting the same piano key over and over again - just to give you a sense of the sound itself and resulting annoyance.

It has seven airbags but interestingly, and unusually, the seventh one is a pedestrian airbag.

This model misses out on lane departure warning but for any families, there are ISOFIX mounts on the rear outboard seats plus three top tethers and you should be able to get three seats back if they’re not too big.

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.

There is a five-year capped-price servicing program which costs a flat $2100, or $420 which is both reasonable for the class and is more affordable than a pay-as-you-go option. There is also a five-year roadside assistance program as a part of your servicing plan through Assist Australia.

Servicing intervals are great at every 12 months or 20,400km, whichever occurs first.
