Isuzu MU-X vs MG MG QS

What's the difference?

The MU-X has plenty of appeal as a daily driver – dependable and it’s a proven 4WD wagon.

Does the 2.2-litre engine add anything substantial to the mix?

Well, it's better than the 1.9-litre, that's for sure, and there's a lot to like about this MU-X in terms of its off-road capability, driver-assist tech, standard features and all-round driveability. And, while the LS-T lacks the top-shelf polish of the X-Terrain, it’s still an appealing potential purchase.

But the 3.0-litre option is better because while the 2.2L is very effective off-road and general day-to-day driving, it lacks grunt and has to work that much harder and is that much noisier under load than the 3.0-litre in most driving scenarios, including 4WDing.

What it lacks in driving panache it does make up for in terms of space and equipments, and there really is room for seven decent-sized humans on board. Combine that with a decade of warranty coverage, and the MG QS will no doubt be appearing on family shortlists.

In terms of appearance, the MU-X remains largely unchanged from the most recent iteration. And that’s a good thing. It’s blocky enough to be recognisable but sleek enough to remain inoffensive. Worth noting the door handles, window trims, front fender accents, roof rails, and side steps on the LS-T are gloss black.

Inside, nothing much has changed (other than a newly-introduced idle start/stop button) and, as such, the MU-X retains a low-key familiarity that makes it a comfortable space. Generally, design-wise, the MU-X more than holds its own against the likes of the Toyota LandCruiser Prado and Ford Everest.

You’re not going to miss the MG on the road, are you? For one, it looks pretty big, and pretty athletic, plus it’s got that bold front-end and grille design that, if I’m honest, I can’t tell if I like, or if it’s over the top. 

Elsewhere, though, it’s more traditional SUV styling, though there is some nice and gentle detailing in the body that makes it look less big, broad, and boring, and the slightly nose-forward design gives the QS something of an athletic stance.

Inside, it’s really quite nice. The twin screens look fantastic – and the subtle curve linking the two looks properly elegant – and there’s some lovely detailing in the through the dash panels, too, which also helps to break up the fact that there is simply a lot of dash here.

As always, I love the row of switches below the screen that act as shortcuts to the functions you need, when you need them, without having to rely on the screen all the time. 

But I'd encourage you to have a good squeeze of all the materials used. Some look like stitched leather, but are actually harder plastics in disguise.

The interior has a familiar and practical feel about it and the cabin is an easy space in which to become comfortable. Controls are easy to locate and operate and charging options are numerous – a mix of USB-A, USB-C (front and second row) and 12V.

Storage places include recesses for the bits and pieces from your pockets, a deep-ish 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.

The MU-X has physical-button options to activate some functions (including to switch on the audio system, to adjust volume and access sat nav).

Seats are comfortable and supportive through all three rows – yes, even the third row is roomy enough to prevent whining from whoever is back there.

My camera guru/photographer/sergeant-at-arms, Glen Sullivan, reminded me that the third-row seats don’t have ISOFIX or top-tether points for child seats. Thanks, mate.

The cargo area is 311 litres with all three rows in use, 1119L with the third row flat and 2138L with the second and third rows stowed away.

The rear cargo area has a cargo cover, tie-down points, a 12V power outlet, a storage space under the rear cargo area floor and a space for tools inside the driver’s side rear cargo wall. The MU-X’s full-size spare (bravo!) is attached to its undercarriage.

The MG QS is a smidge under five-metres long, just over 1.9m wide and just under 1.8.m high, which puts it right in the seven-seat SUV ballpark.

That pays dividends in the backseat. I’m 175cm tall, and I had heaps of room to spread out, and I don’t only have my own air vents, but I have my own temperature controls, too.

It’s a big and airy space, and I’d have no problem spending some serious time here on a longer road trip.

But the big question is, what do those dimensions mean for third-row riders, and does it live up to its promise of being a true seven-seater?

Well, yes and no. The fact that the middle row is on rails helps massively, because you can slide it forwards to maximise leg room for backseat riders, and the one-touch entry (which folds the middle row up and forwards) makes actually climbing back there pretty simple, too.

But... it's still a space in which I wouldn't want to spend too much time. Its big enough for shorter trips, but it's still best for the smaller kids in the family.

Now, as is often the case with three-row cars, how much boot space you get very much depends on how many people you have onboard. With all three rows in place, you get a miserly 203L, fold the third row and you get 517L, drop both rows and you get 1052L.

You get introductory national drive-away pricing for the two-grade MG QS range, with the Excite yours for $46,990, and the Essence we’re testing sets you back $50,990 on the road.

In typical MG fashion, neither model is wanting for much in the spec department, but our Essence gets the lot and the kitchen sink.

Outside, there are 21-inch alloys, LED lighting with fog lights, a powered tailgate and a powered sunroof. Inside, there are leather seats which are heated and ventilated up front, tri-zone climate control and ambient interior lighting.

Tech is handled by twin 12.3-inch screens with wireless Apple CarPlay and Android Auto. There’s wireless charging, too, and a 12-speaker Bose stereo.

The top-spec model also gets all-wheel drive, adaptive suspension and six drive modes — Normal, Snow, Off-Road, Sport, Custom and Eco.

There are five exterior colours available on the QS, including Oxford White, Black Pearl, Camden Grey, Regency Green and Cashmere Silver.

This MU-X has a 2.2-litre, four-cylinder, turbo-diesel engine, producing 120kW at 3600rpm and 400Nm between 1600-2400rpm and it’s matched to an eight-speed automatic transmission.

Worth noting the 3.0L MU-X has a six-speed auto and produces 140kW (at 3600rpm) and 450Nm (1600-2600rpm) while the outgoing 1.9L MU-X has a six-speed auto and produces 110kW (3600rpm) and 350Nm (1800-2600rpm).

While the 3.0-litre has always been unstressed in most driving scenarios – even low-range 4WDing – the 2.2-litre feels underpowered. More about that in the ‘Driving’ section below.

The MU-X has a part-time 4WD system which includes a dual-range transfer case (with high- and low-range 4WD) and a rear diff-lock. The driver is able to shift from 2H (two-wheel drive, high-range) to 4H (4WD high-range) while on the move up to speeds of 100km/h. The diff-lock may only be engaged when the vehicle is in 4L (4WD low-range).

The MU-X also has a switchable terrain mode system which tweaks the engine, transmission and traction control to suit the driving conditions. 'Rough Terrain' mode, like a steroids-enhanced off-road traction control, is king of these modes when you’re off the bitumin.

Under this hood is a 2.0-litre turbocharged petrol four-cylinder engine, which produces 153kW and 360Nm. In this all-wheel-drive Essence, that power is channelled through a nine-speed automatic and sent to all four wheels.

I don’t have a zero to 100km/h time for this two-tonne-plus beast, but suffice it to say it won’t knock your hat off. I’m guesstimating just under 10 seconds.

Official combined cycle (urban/extra-urban) fuel consumption for this MU-X is 6.7L/100km. The 1.9L MU-X offers 7.4L/100km while the 3.0L offers 7.6L/100km.

Actual fuel consumption on this test was 8.7L/100km.

The MU-X has an 80-litre fuel tank, so, going by that on-test fuel consumption figure, you should be able to get a driving range of about 920km. But remember, your fuel consumption may be completely different to mine because chances are you'll have friends, family pets, sporting equipment, camping gear, the whole kit and caboodle on board. I've only been carrying vehicle recovery gear, MaxTrax, and a first-aid kit, so I haven't had a huge amount of weight on board.

Now MG reckons you will see 8.8L/100km on the combined cycle, which would give you a theoretical driving range of around 738km from its 65-litre fuel tank. For the record, we saw more like 11 litres.

That tank, by the way, demands 95RON fuel, so you won’t be troubling the cheapest pump at your local service station.

Before we launch into the off-roading section of this test, it’s worth noting the MU-X has always been decent on-road; composed, reasonably refined (for a 4WD wagon, anyway) and comfortable. And thankfully, with the 2.2-litre engine, not all of those characteristics have been thrown out the window.

It is quite noisy, especially under pressure when you have to do some heavy acceleration or when you have a bit of gear on board. When it has to work that bit harder than it usually does, it can become quite noisy. Admittedly, the 3.0-litre MU-X is also quite gruff, but there's an edge to the roughness in the 2.2-litre that is very noticeable on road.

This MU-X is quite sluggish off the mark, exhibiting a disconcerting lag under heavy throttle from a standing-start. And it’s far from the most dynamic vehicle to drive. But it has a tractability about it that manages to mostly negate these flaws.

Otherwise, the new eight-speed auto deserves credit as it’s slick and smooth in application and feels right at home in this wagon.

Now to off-roading. The MU-X is still very capable. In fact, even with the 2.2-litre engine, it remains one of the better-performing 4WD wagons straight out of the dealership, in terms of pure off-road capability.

The 3.0-litre MU-X is not the torquiest in this segment, but it offers ample pulling power available across a wide rev range – count on peak torque between 1600rpm and 2400rpm – and it delivers that pulling power in an even-handed fashion. The 2.2-litre MU-X has to work harder than its stablemate, and it’s noisier and harsher.

However, those characteristics don’t take away from how effective this MU-X is because it offers impressive off-road performance. It still has a decent amount of low- and mid-range torque, which makes dirt-road cruising and low-speed 4WDing easy.

The MU-X has part-time 4WD with high- and low-range 4WD gearing, a rear diff lock and overall it retains all of that off-road capability the 3.0-litre MU-X has been renowned for – so you don't lose any efficacy there.

The line-up’s off-road traction control system, which once was a bit patchy in its effectiveness, has gone through a couple of phases and it’s been recalibrated/tweaked over the years and it is much better now.

Of course, the MU-X also has Isuzu’s much-vaunted Rough Terrain mode (a form of early-acting off-road traction control which converts lost grip into torque for the wheels with grip), and it is smooth and effective, giving the driver better overall control in challenging terrain.

Some of this MU-X’s listed off-road angles appear shallower than the 3.0-litre MU-X’s – approach: 23.9 (3.0L = 29.2), departure: 26.4 (3.0L = 26.4) and ramp-over: 19.6 (3.0L = 23.1) – but, even if that is the case, it has very similar driving characteristics in low-speed, low-range four-wheel driving to its 3.0-litre stablemate.

If you drive with control and consideration, you shouldn't have any trouble tackling light to moderate 4WDing in this MU-X. It could even, if push comes to shove, handle challenges that may be considered by some to be on the edge of hard-core 4WDing – for a showroom-standard 4WD wagon anyway.

Ground clearance is 235mm and wading depth is 800mm, so there’s an adequate amount of clearance to work.

The MU-X – with a turning circle of 11.6m and a kerb weight of 2130kg (3.0L = 2185kg) – feels quite nimble on bush tracks.

This wagon’s wheel travel – how far the axle can move up and down relative to the chassis – has more than an adequate amount of flex, stretching its tyres close, if not all the way, to the dirt.

A noticeable trade-off is its 20-inch wheel-and-tyre combination, which is best suited to sealed surfaces and so are far from ideal for dirt-track touring. There’s an easy remedy, though. Buy a set of decent all-terrain tyres on 17- or 18-inch rims to replace the showroom-standard 265/50R20 Highway-Terrain tyres. If you are using your MU-X, avoid dropping pressures too much because you’ll risk sidewall pinches and punctures on these low-profile road tyres.

In terms of packability: the 2.2L MU-X has a listed payload of 670kg, whereas the 3.0L version offers 615kg.

The 2.2L MU-X can legally tow 750kg (unbraked trailer) and 3500kg (braked), so theoretically you can tow the same load as a 3.0-litre MU-X. But, as mentioned, the 2.2-litre engine feels underpowered, even in general day-to-day driving, so with a load and/or towing that’s an added burden.

For reference, the 2.2L MU-X has a listed gross vehicle mass of 2800kg and gross combined mass of 5900kg.

It all comes down to what you're looking for in your large SUV. Is it a vehicle that – against all odds – manages to somehow stir your emotions from behind the wheel, whether you're flying solo or you're riding with seven on board? Well, the MG QS won't do that.

But if you're looking for something big, comfortable, nicely trimmed and with just about every feature you can think of, then the MG QS ticks those boxes and then some.

But let's start with the not so good. The steering in the MG QS is super, super light, leaving it feeling largely disconnected from what's happening beneath the tyres, and giving the drive experience a weird and artificial vibe.

Now, it must be said that some drivers like that. A big car with light steering makes manoeuvrability easy in car parks and the like. But I don't. It makes me feel uninvolved in the drive experience.

The QS is equipped with Sport mode that does add heft to the steering, but which also appears to make the gearbox way to eager to shift down and hold a lower gear, adding a harshness to the drive.

It's also not a big engine, and this is a big car, and so there's a bit of delay when you first plant your foot as the engine figures out its next move, and you're always aware of the engine working fairly hard to get the QS moving along – though MG has done a good job of deadening much of that sound before it enters the cabin.

But if that's the not-so-good, there are still plenty of ticks in the MG's plus column. It's a largely smooth-riding, sweet-shifting proposition, the QS, and the space in all three rows is impressive, especially when the sliding second row is utilised to maximise the space where you need it.

The MG QS hasn’t yet been crash-tested by ANCAP, but all the expected safety kit is on board, including seven airbags, AEB, rear cross-traffic alert, adaptive cruise control, blind-spot monitoring, lane-keep assist and lane departure warning.

But be warned, it can bing and bong and random intervals. If it thinks you’re speeding, or that you’re not paying attention, and it is very, very annoying. Learn how to switch off the speed limit recognition and driver attention alert, and fast.

The MU-X has a six-year/150,000km warranty and seven years of roadside assistance. Unlimited km in the warranty would be welcome.

Service intervals are scheduled for every 12 months or 15,000km, whichever occurs soonest.

Capped price servicing covers the first five scheduled services for MY24 and later vehicle models (up to 5 years/75,000km – whichever occurs first) – at a flat price of $469 for each service.

Isuzu Ute Australia has a nationwide network of more than 160 dealer sites.

It’s a tale of goods and bads in the QS ownership world. The good is a near market-leading 10-year/250,000km warranty (so long as you regularly visit an authorised service centre), and solid service intervals of 12 months or 15,000km, whichever comes first.

The bad is eye-watering service costs – including a whopping $2920 dollar service at the six-year/90,000km mark.

All up, seven years/105,00km of servicing will cost you $6336 in the 2WD, or $6962 in our AWD – the latter averaging out at close to $1000 per year.
