Isuzu MU-X


Mazda CX-30

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?

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.

Mazda CX-307.6/10

About to enter its fifth year in market the Mazda CX-30 is holding up well and this GT SP FWD grade delivers solid value relative to its key competitors, of which there are many. It’s also space-efficient, practical and performs well with top-shelf safety, decent refinement and good dynamic ability.

Alternately, it’s crying out for a hybrid powertrain to improve fuel efficiency, the interior form and function is starting to date and while it meets the market the ownership promise could be sharper. But this little SUV is still worthy of a spot on your new-car short list.

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.

Mazda CX-30

Mazda continues to follow a disciplined design path with everything from the MX-5 sports car to the BT-50 dual-cab ute sharing key attributes like the brand’s signature trapezoidal grille, simple flowing lines and sleek head- and tail-lights, all wrapped up with a subtle hint of chrome here and there.

Car-spotters with the GT SP on their checklist should look out for 18-inch black metallic rims as well as black exterior trim, including the mirror caps. 

Inside, the CX-30 maintains Mazda’s restrained approach with smooth surfaces integrated across the multi-layer dash and primo leather-trimmed seats.

That said, this car is starting to show its age with the multimedia screen plonked on the top of the dash (in typical Mazda fashion) and a largely conventional instrument cluster.

Yes, the main dial is configurable courtesy of a central 7.0-inch TFT screen, but next to more recent arrivals boasting sleek, often twinned, flat screen displays the CX-30 looks and feels out of touch. 

Functionally, there’s a sensible mix of digital controls and physical buttons (points for audio volume and ventilation dials!), but… the multimedia screen can only be accessed by a rotary controller in the centre console once the car is mobile (it works as a touchscreen when you’re stationary).

Some say touchscreens take your eyes off the road so the controller makes sense, but with a sequential app like Spotify it can take a lot of twirls to get to where you want to go, which upsets concentration and takes your eyes off the road, anyway. I’d prefer the relative ease of a quick press on a screen.

Aside from all that, the materials used are high quality with soft-touch surfaces across key contact points and hard plastics confined to high-wear areas. 

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.

Mazda CX-30

At just under 4.4m long, close to 1.8m wide and little over 1.5m tall (with a 2655mm wheelbase) the CX-30 is in the middle of the pack it competes with in terms of key dimensions.

And space up front is more than adequate, with an impressive feeling of roominess for a relatively small SUV.

For storage, there’s a large lidded box (which doubles as an armrest) between the front seats as well as a pair of cupholders in front of the gear-shifter with a bay for wireless device charging ahead of that.

The glove box is big, there are bins in the doors with room for decent size bottles and a drop-down tray for sunglasses sits overhead.

Move to the rear and the amount of space on offer is surprisingly generous. Sitting behind the driver’s seat, set for my 183cm position, I have plenty of head and legroom, although three full-size adults across the back seat will be an uncomfortable proposition for anything other than short trips. A trio of up to mid-teenage kids will be fine.

Adjustable air vents at the back of the front centre console are a welcome inclusion for back-seaters and storage runs to a map pocket (weirdly, on the back of the front seat only), a pair of cupholders in the fold-down centre armrest and bins in the doors with room for smaller bottles.

In-cabin power and connectivity includes two USB-C outlets and a 12-volt socket in the front centre storage box. No USBs specifically for those in the rear, which is a miss for road trips and no 12V in the boot which can be handy when camping or picnicking.  

Speaking of the boot, cargo volume with the rear seat upright is okay for the class at 317 litres, which expands to a healthy 1479L with the 60/40 split-folding backrest lowered. For comparison the Kia Seltos coughs up 433L with the rear seat upright.

The space is illuminated, there are tie-down anchors to help secure loose loads and there’s a space-saver spare sitting under the floor.

And if you’re keen on towing a tinnie or similar you’re good to go for a 1200kg braked trailer (600kg unbraked).

Mazda CX-30

The Mazda CX-30 G25 GT SP FWD weighs in at $43,140, before on-road costs and our test example features the optional ‘Vision Pack’, the details of which we’ll get to shortly, raising the price $1300 to $44,440. 

Alternate options around that price point include the Hyundai Kona Premium N Line 2WD ($42,500), Kia Seltos GT-Line FWD ($41,850), Mitsubishi Eclipse Cross Exceed 2WD ($40,990), Honda HR-V e:HEV L 2WD ($42,900, drive-away), Nissan Qashqai ST-L FWD ($42,690), Peugeot 2008 GT FWD ($44,490), Renault Arkana Techno FWD ($41,000), Suzuki S-Cross Plus FWD ($41,490), Toyota C-HR 2WD GXL Hybrid ($42,990) and Volkswagen T-Roc Style FWD ($40,590).

That’s quite the automotive smorgasbord, the resulting price and specification cage fight meaning every included feature counts and the Mazda heads into battle with some significant weapons in hand.

Specifically, dual-zone climate control, a head-up display, a 10.25-inch ‘widescreen’ multimedia display, 7.0-inch driver’s multi-information display, 12-speaker Bose audio (with digital radio), wireless Android Auto and Apple CarPlay, ‘Burgundy’ leather seat trim, heated front seats, leather trim on the gearshift and heated steering wheel, wireless phone charging, power-adjustable driver’s seat (with memories), a glass power tilt and slide sunroof and a power tailgate.   

There’s also adaptive auto LED headlights, 18-inch black metallic alloy wheels, radar cruise control (with stop/go), a reversing camera, auto-fold (and tilt) heated exterior mirrors and keyless entry and start. 

It’s an impressive and competitive equipment list for a small SUV under $45K, even before we get to the performance and safety tech covered later in the review.

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.

Mazda CX-30

The CX-30 GT SP is powered by a 2.5-litre, naturally aspirated, four-cylinder petrol engine producing maximum power of 139kW at 6000rpm and peak torque of 252Nm at 4000rpm.

It’s a proven all-alloy unit featuring direct-injection as well as variable intake and exhaust valve timing with drive going to the front wheels via a six-speed auto transmission. 

The AWD version of the GT SP adds an electromagnetic multi-plate clutch pack (managed by a multitude of sensors) to selectively engage the rear wheels, as well. But its engine and transmission combination is identical to this FWD model’s.

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.

Mazda CX-30

The CX-30 GT SP FWD’s official fuel consumption figure on the combined (urban/extra-urban) cycle is 6.6L/100km, the 2.5-litre atmo four-cylinder engine emitting 154g/km of C02 in the process.

It features fuel-saving stop-start and cylinder deactivation functions as standard and over a combination of city, suburban and some freeway running we saw an average of 8.4L/100km, which is average for an SUV in this class. A comparable hybrid package would easily better this result.

Based on the car’s 51-litre fuel tank theoretical range between refills is 772km, which drops to just over 600km using our real-world test consumption number. But the good news is this CX-30 runs happily on cheaper 91 RON ‘standard’ fuel.

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).

Mazda CX-30

It’s rare in 2024 to find a small SUV that doesn’t have at least one turbocharger attached to its engine, the CX-30’s 2.5-litre ‘atmo’ four being one of those increasingly scarce examples.

But Mazda’s been laser-focused on extracting maximum power and efficiency from its non-turbo petrol engines for yonks and this one stands up well.

It doesn’t have the low-down punch a turbo typically delivers but maximum pulling power arrives at a useable 4000rpm and it’s eager enough for easy city and suburban running as well as confident freeway cruising.

Although Mazda doesn’t quote an official number you can expect a sprint from 0-100km/h in around 8.5 seconds, which is quick for the class.

Worth noting engine noise and a raspy exhaust note make their presence felt under acceleration and the throttle isn’t as refined as it could be. Not a huge deal, but a slight jerkiness is evident on initial, especially moderate, acceleration.

The six-speed auto is smooth and fuss-free, the steering wheel paddle shifters on hand if you need to intervene and select a specific ratio. ‘Sport’ mode peps things up, causing the transmission to shift down earlier and up later. But it’s aggressive in that it often holds onto a gear for too long and you find yourself diving back to the default normal setting.

Tipping the scales at just under 1.5 tonnes, the CX-30 is underpinned by a MacPherson strut front, torsion beam rear suspension and ride comfort on typically pock-marked urban surfaces is average for the category. That is, a bit jittery over bumps and corrugations but there’s no bone-jarring going on here.

Steering feel and response is good and the grippy steering wheel helps with a connection to the front tyres. Speaking of which, the standard rubber is high-performance (215/55) Dunlop SP Sport Maxx 050 which is  grippy and commendably quiet. 

Push on into a corner and the CX-30 remains balanced and predictable with body roll well under control. Torque vectoring, by engine and physical braking, is also onboard to reel things in if you overstep the mark.

Braking is by discs all around, vented at the front and solid at the rear, and they wash off speed effectively with a satisfyingly progressive pedal action.

Vision is good, which combined with the CX-30’s compact dimensions and 10.6m turning circle, means parking is easy. Especially when you factor in the hi-res reversing camera and front and rear 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.

It scored a stunning 99 per cent in the adult occupant protection category and an impressive 88 per cent for child occupant protection.

Active (crash-avoidance) tech includes AEB (operating from 4.0-160km/h) as well as lane keep assist, lane departure warning, traffic sign recognition, intelligent speed assistance, blind-spot monitoring, front and rear parking sensors, rear cross-traffic alert, a reversing camera and tyre pressure monitoring.

Mazda’s ‘Vision Pack’ is also standard which includes a 360-degree camera view, ‘Cruising & Traffic Support’, driver fatigue monitoring and front cross-traffic alert.

The airbag count runs to seven - dual front and front side, full-length side curtains and driver’s knee.

There are three top tether points for child seats across the second row with ISOFIX anchors on the two outer positions.

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.

Mazda CX-30

Mazda covers the CX-30 with a five-year/unlimited km warranty which is the norm in the mainstream market, and it’s worth noting a growing number of competitors are now at six, seven or even 10 years, although the latter are typically conditional on authorised dealer servicing. Roadside assistance is provided for the duration of the warranty.

Service is recommended every 12 months or 15,000km and Mazda’s ‘Service Select’ program sets maintenance pricing out to seven years, the lowest over that period being $352 and the highest $626, for an annual average of $459, which is reasonable but not exceptional for the category.

For comparison, a similarly specified Toyota C-HR averages $330 per workshop visit over the same period.
