MG ZST vs Isuzu MU-X

What's the difference?

Will the MG ZST Essence fit a small family? Absolutely, and all but the middle seat passenger will be comfortable but there are areas open for improvement. Like it's safety, laggy tech and adding a few extra items in the back seat.

Yet, it still offers a good host of features and an attractive package for a reasonable price tag. Unfortunately, my son missed having the basic amenities but did like the sun roof.

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.

Being the newer and shinier version of the ZS, the ZST presents as a nice little package with its full suite of LED exterior lights, shiny chrome accents and its well-shaped body.

The front is distinctively different from its design muse with a darkened grille, and redesigned fog lights that feature new air intake vents. Other highlights include the 17-inch two-tone alloy wheels with sporty red brake calipers lurking behind them.

The interior is pleasant with a massive sunroof creating a light-filled space and giving the illusion that the cabin is larger than it is.

The synthetic leather upholstery and trims seem robust and perfect for families, but also feel quite plasticky under hand. The red badge embossing on the headrests is lovely, though.

The dashboard is well-proportioned and headlined by an upgraded 10.1-inch touchscreen multimedia system and fully digital instrument cluster.

The gearshift feels a tad too skinny and tall for the general aesthetic but the circular air-vents add some cute personality.

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.

Practicality is hurt by a lack of individual storage options and a back seat that has only two USB-A ports for its amenities.

The cabin space is spacious, though, and both rows have a decent amount of leg- and headroom despite the massive sunroof.

The steering wheel features height but not reach adjustment and to accommodate I have to sit much closer to the wheel than normal thanks to my poor little T-Rex arms.

Individual storage is the best up front with a small middle console and glove box, two cupholders and two drink bottle holders. The doors also feature large storage bins, which is great to keep the cockpit feeling neat.

The rear row gets two map pockets and a small storage bin in each door. There is also a (very) shallow storage nook at the back of the middle console… think a packet of gum or small wallet size.

My seven-year old isn't as comfortable in the rear because it lacks directional air vents, reading lights and a fold-down armrest. All items which will hinder an adult's comfort, too.

The boot space is a good size at 359L but you can bump it to 1187L with the rear seats folded, the backrest featuring a 60/40 split.

The height of the floor is adjustable and when set in the lowest position creates a deep well to tuck larger items, like luggage, into.

The hard cargo cover can be awkward to shift around or store but is otherwise out of the way when it counts.

Other amenities accentuate the premium-feeling the Essence is going for with the heated front seats and electric drivers seat offering well-padded comfort but on longer journeys, I miss having adjustable lumbar support.

The rear seats aren't as comfortable as the front only because the synthetic leather feels slippery, which is accentuated when you hit corners!

In terms of technology, you get two USB-A ports in each row but the front also gets a 12-volt port. You miss out on fast and wireless charging options.

The multimedia system looks great but can be sluggish to respond and the apps can be slow to load but I like the built-in satellite navigation.

The upgraded sound system has six speakers instead of four but the sound quality is a bit tinny with music and calls.

It was simple to connect to the wired Apple CarPlay. It also has Android Auto, Bluetooth connectivity and AM/FM radio.

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 new MU-X with a 2.2-litre, four-cylinder, turbo-diesel engine is available with a 4×2 or 4×4 drivetrain in several variants. Don’t worry, the 3.0-litre is still in the line-up.

Our test vehicle has the 2.2L and, it is priced at $71,400 before on-road costs.

Standard features include a 9.0-inch multimedia touchscreen system with sat-nav, wireless Apple CarPlay and Android Auto, an eight-speaker sound system, eight-way power-adjustable driver’s seat (four-way power-adjustable front passenger seat), heated front seats, a 7.0-inch driver display and 20-inch alloy wheels shod won 265/60R20 Bridgestone 684II HT tyres.

It also has white ambient interior lighting, remote engine start, rear privacy glass, power-folding and heated door mirrors (with side cameras) finished in gloss black, and leather-accented upholstery with grey stitching and synthetic leather on the door trims and centre console.

Exterior paint choices on the MU-X LS-T include 'Mineral White', 'Basalt Black mica', 'Moonstone White pearl', 'Magnetic Red mica', 'Neptune Blue mica', 'Mercury Silver metallic', and 'Obsidian Grey mica'. Anything other than standard Mineral White costs an extra $695.

The Essence variant has a 1.3-litre, three-cylinder turbo-petrol engine with a maximum power output of 115kW and 230Nm of torque.

It's a front-wheel drive and features a six-speed auto transmission. Overall, it has enough power to keep up with traffic on the open road but you have to be firm with the accelerator to keep your speed consistent.

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.

The official combined cycle fuel figure is 7.3L/100km and my real-world average came in at 7.7L. That is after a good mix of urban and open-road driving, so the usage is good.

Based on the combined fuel cycle and the relatively small 45L fuel tank, expect a driving range of around 616km.

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.

The ZST Essence has an okay amount of power relative to the car's small size.

It's an adequate cruiser when I ferry just my husband and son around, but feels a full load of luggage and people.

The steering is responsive and it's an easy car to manoeuvre in tight car parks or city streets, which is great. The visibility is pretty good despite the chunkier pillars and you feel confident when checking your blind-spots.

While the suspension is fairly forgiving and ride comfort is decent, you will still notice the bumps, especially when seated in the back.

The cabin suffers from some wind and road noise and at higher speeds we had to find we raise our voices a bit to be heard. Around town, you don't notice it.

This is just a personal preference but the brake and accelerator pedals are skinnier and more centrally positioned than I prefer. You get used to it, though.

The ZST is pretty easy to park and it's great that you have a 360-degree camera system but the image quality can be grainy. You get rear parking sensors, too, but miss out on ones at the front.

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.

The MU-X has the maximum five-star ANCAP safety rating from testing in July 2022.

Standard safety features include eight airbags - dual front, dual front side, dual full-length curtain, front knee and centre (far-side) - and a comprehensive suite of driver-assist tech including AEB, adaptive cruise control, lane-keep assist, lane departure warning, a digital reversing camera and a tyre-pressure monitoring system.

Remember, the third-row seats do not have ISOFIX or top-tether points for child seats.

The ZST Essence comes with a seven-year/unlimited km warranty, which is on par with coverage offered by a growing number of its rivals.

There is a seven-year or up to 70,000km servicing program for a total cost of $2339 or an average of $334 per service, which is very competitive for the class.

Servicing intervals are at every 12 months or 10,000km, whichever occurs first, but could be annoying if you travel a lot.

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.
