Isuzu MU-X vs Kia Sportage

What's the difference?

The MU-X has always had plenty of appeal as a daily driver – dependable, not dynamic – and it’s a proven 4WD wagon.

Some people don't like the noisy, sluggish engine, but I don't mind it because it delivers off-road.

There was already a lot to like about the seven-seater wagon in terms of its off-road capability, driver-assist tech, standard features, and simple all-round driveability, and the X-Terrain – which encompasses all of that AND adds some polish to the mix – is an impressive top-shelf addition to the MU-X line-up. Even if it's so pricey...

The Sportage still feels like a super solid offering in its segment, plus the addition of more hybrid options is only going to help.

It does feel a little under-specced in the lower grades, though, considering the everything-and-the-kitchen-sink approach taken by its Chinese rivals.

I feel like I should almost whisper this bit, given it's a dirty word at the moment, but that diesel engine, it's a real peach, and if I wasn't afraid of being run out of Sydney's inner west with pitchforks, that's probably the one I'd be choosing.

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

As I’ve said before, the MU-X has never been particularly exciting or boring in terms of design, just comfortably adopting a low-key, middle-of-the-road type design – sales gold, in other words.

But the X-Terrain has distinctive ‘X’ branding here and there – inside and out – and that adds a subtle class to this variant.

The X-Terrain is 4860mm long (with a 2855mm wheelbase), 1870mm wide (excluding mirrors), 1825mm high and has a listed kerb weight of 2195kg.

It has a wheel track of 1570mm and an 11.6m turning circle. 

Our test vehicle has the exclusive X-Terrain paint – slate grey metallic – which matches well with the X badging, bigger grille design, new headlights, three-tier LED tail-lights, and redesigned wheels.

The interior strikes a stylish note as well with red stitching on the dash, centre console and leather-accented seat trim.

All new Sportage models feature a redesigned front and rear end, but they actually have a slightly different look. There's one look for the cheaper models and then one for the top-spec cars, the SX+ and GT-Line.

The changes aren't overwhelming, though. There are fog lights in the more expensive models, but also just more use of black edging, as opposed to the silver edging that frames the bottom of the grille and rear end in the cheaper cars.

Either way, I still really like the way the Sportage has come together. The front end looks bold and powerful, mostly because of the vertically stacked headlights and and the DRLs that really frame the front end, but they've also done a good job of making a fairly big and spacious SUV feel small and not too imposing.

Now, inside the top-spec cars it’s very modern Kia, with a big twin-screen setup, and the dual-function bar beneath them that handles things like climate control, but also mapping and media and those kinds of functions. The cheaper models also get the same look, but swap the second 12.3-inch screen for a smaller driver display.

It means you don't have to dig through the screen for everything, which is always a nice touch. And I also like some of the materials used in the GT-Line, too, like the synthetic wood grain that’s actually nice to touch.

But there are a couple of key downsides. Not quite so much in the top-spec cars, but in the cheaper versions. I hate those constant reminders that you didn't spring for a more expensive model, and there are plenty of those in the lower-spec cars.

In the more expensive models, there are buttons alongside the gearshift, but in the cheaper cars, those buttons are still there, just blacked out and inactive. And even the cutout for the head-up display still exists in the cheaper cars, but of course, there's no head-up display.

All of that combined with some hard and scratchy plastics front and back makes you really want to dig deep for a more expensive Sportage.

The interior has a pleasant, familiar and practical feel about it and this is an easy space in which to swiftly become comfortable. 

Controls are easy to locate and operate and charging options are numerous – a mix of USB-A, USB-C and 12V up front, and USB-A for the second row.

Storage places 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 cupholders either side of the third row in the MU-X for passengers riding back there.

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).

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

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 folded.

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 Sportage measures 4685mm long, 1865mm wide and between 1665mm and 1680mm tall, depending on the trim.

Slip into the backseat of the Sportage and you’ll find legroom is ample, at least for my 175cm frame, and headroom is ok, without being great - though our test car had the sunroof fitted which could be eating into the space.

Elsewhere in the back though, even the top spec GT-Line just doesn't feel that plush. And by that, I mean some of the materials are a bit hard and scratchy, you don’t get your own temperature controls for the air vents, and it generally just lacks a premium air.

Now, to the all-important point in this segment, and that is boot space. The official VDA numbers are 543-1829 litres for the petrol and diesel cars, and 586-1872L for the hybrid, but the real-world reality is a boot that is deep and wide and really has enough space to carry plenty of groceries.

But there is an important caveat. Under the flat floor there is a temporary spare wheel in the hybrids, where in some of the ICE cars, you get a full-size spare wheel.

There are a lot of different numbers involved in the Sportage story. In fact, there are no less than 13 trim and powertrain combinations, and so 13 different prices you can pay. Easier, I think, if I just pop the graphic up on screen and you can jump to the one you want.

While there are four engines and five powertrain configurations to choose from, not all of them are available across all four trim levels. The SX+, for example, offers no electrified options, while the SX will give you hybrids, but no turbo-petrol choice.

The range opens with the S, which gets 17-inch alloys, LED DRLs, power-folding mirrors and roof rails, while inside there are cloth seats, power windows, a smart key with push-button start, and single-zone air-con with rear-seat vents. Tech at this level is handled by a 12.3-inch infotainment screen with wireless Apple CarPlay and Android Auto, but no wireless charging, which pairs with a six-speaker stereo. The driver then gets a 4.2-inch screen to deliver driving info.

The SX then adds 18-inch alloy wheels, dual-zone climate, standard navigation and rain-sensing wipers.

The SX+ is feeling like a sweet spot, adding 19-inch alloys, LED fog lights, artificial leather seats that are heated up front, wireless device charging, a heated steering wheel and a better Harman Kardon Premium stereo.

Finally, the flagship GT-Line gets the lot, with 19-inch black alloys, or 18-inch wheels in the hybrid, welcome lights, projection headlights, a twin-screen cabin which adds a second 12.3-inch screen for the driver, a powered driver’s seat and a head-up display.

All models also get Kia Connect, which gives you remote access to the vehicle for things like pre-setting the climate, as well as Over the Air updates.

I’ve got to say, though, the flagship Sportage offers largely what the cheapest version of most Chinese SUVs offer, showing just how much price pressure the newcomers are putting on the old guard.

The MU-X has a 3.0-litre four-cylinder turbo-diesel engine, producing 140kW and 450Nm and it’s matched to a six-speed auto.

These form part of a proven powertrain and while the MU-X may not be the most dynamic vehicle to drive – it’s acceleration is sluggish rather than punchy – it has a real tractability that nullifies any other niggles.

It has part-time 4WD, with high- and low-range as well as various drive modes, rough terrain mode, and a rear diff lock.

The big news about this mid-life update for the Sportage is the expansion of Kia’s hybrid powertrain, which is now available with AWD, and the inclusion of an eight-speed automatic for the 1.6-litre turbo-petrol variants.

Elsewhere, the 2.0-litre petrol option produces 115kW and 192Nm, pairs with a six-speed automatic, and drives the front wheels. The other pure petrol option is a 1.6-litre turbocharged petrol unit that produces 132kW and 265Nm, paired with an eight-speed auto and powering all four wheels.

Then comes the diesel, which is a 2.0-litre unit making 137kW and 416Nm. It pairs with an eight-speed automatic and powers all four wheels.

Finally, there’s a hybrid option, now with two- or all-wheel drive. It pairs a 1.6-litre turbo-petrol engine and a six-speed automatic with an electric motor and a 1.49kWh lithium-ion battery to produce a total 173kW and 367Nm.

Official fuel consumption for this MU-X is 8.3L/100km and that's on a combined cycle. 

On this test I recorded 10.2L/100km. I did a lot of high and low-range four-wheel driving, so that fuel consumption is not too shabby.

The MU-X has an 80-litre fuel tank, so going by my on-test fuel consumption figures you could reasonably expect a driving range of about 784km from a full tank. 

All pure ICE Sportage grades are fitted with 54-litre fuel tanks, while the hybrids get 52-litre tanks. But the hybrids more than make up for it when it comes to fuel efficiency, with the FWD sipping a claimed 4.9 litres per hundred kilometres on the combined cycle, while the AWD drinks 5.3 litres.

The diesel is the next most-efficient, using a claimed 6.3L/100km combined, while the turbo-petrol needs 7.5 litres, and the 2.0-litre petrol requires 8.1 litres.

Our calculations suggest that, taking the fuel claims at face value, a 2.0-litre petrol Sportage should carry you 666kms on a full tank, while a turbo-petrol will take you 720kms. The diesel should deliver 857kms, while the FWD hybrid (1061kms) and AWD hybrid (981kms) will take you the furthest.

In previous tests, the MU-X has been fine on road and more than adequate on gravel, dirt tracks, and during low-range 4WDing. But it’s been a jarring, skippy ride on irregular surfaces rather than as composed as it could – and should – have been. The culprit? Firm suspension, over-inflated tyres, too-tight trousers, who knows?

The good news is it seems like Isuzu has ironed out any issues in the suspension, minor or otherwise, because the MU-X is now is a lot better in terms of ride and handling than ever before. 

Off-road, the MU-X has always been a proven combination of its 3.0-litre, four-cylinder turbo-diesel engine, clever six-speed automatic transmission, and an off-road traction control system that's been increasingly well recalibrated through a number of generations. 

The engine is tractable and gruff, it has plenty of grunt and, as long as you're not driving like a complete hoon, you can usually get through most obstacles without a lot of fuss.

It's this mix of mechanicals and driver-assist tech that make the MU-X such an effective 4WD package. And there are a number of reasons for that. 

For one, that engine delivers plenty of torque down low and in the mid-range torque and that's crucial for four-wheel driving. 

And another thing, Rough Terrain Mode – like a beefed-up and fine-tuned off-road traction control – proves very effective because it punches torque to the wheel with the most traction – while wheel spin on tyres that aren't touching dirt is minimised – and that way it keeps the vehicle moving through obstacles with safe and controlled momentum. 

As I’ve noted before though, Rough Terrain Mode is not a magic all-conquering solution, but it is another handy addition to the MU-X’s off-road toolbox.

And the MU-X also has a rear diff lock to back you up – and that's another valuable component. 

The MU-X has approach, departure and ramp-over angles of 29.2, 26.4 and 23.1 respectively.

A listed 235mm of ground clearance is about standard for this kind of wagon but, as I’ve said before, it seems vulnerable in the underbody, side steps and its plastic mud guards. So the underbody may touch dirt, depending on how challenging the terrain is. 

Wading depth is listed as 800mm.

But, as always, with focused driving, you’ll have lots of fun and you'll minimise any superficial damage or scuff marks to the MU-X.

The MU-X has plenty of potential as a touring platform, but, if you’re planning to do any off-roading beyond well-maintained tracks, then get rid of its road-biased tyres and replace them with all-terrain tyres.

The showroom-standard tyres on this MU-X – 265/50R20 Bridgestone Dueler HTs – are okay, but not really up to scratch if tough 4WDing is what you’re keen to do. I’d prefer an 18-inch wheel and tyre package with decent all-terrains.

The MU-X has a full-sized underslung spare and in terms of packability, the MU-X X-Terrain has a listed payload of 605kg, GVM is 2800kg and GCM is 5900kg.

If you are considering using your MUX as a tow vehicle, it's handy to know that it can legally tow 750kg (unbraked) and 3500kg (braked), which is the standard for large four-wheel-drive wagons. 

Be aware though that, as with any other vehicles, once you're towing anywhere near the maximum weight, your payload is greatly reduced.

I want to start this with just a small caveat. It hasn't been the most comprehensive drive of this car so far. And remember, there are a lot of variants.

Petrol, diesel, hybrid, two-wheel drive, all-wheel drive – we haven't driven all of them, and so I feel uncomfortable giving you my rock-solid verdict across the whole range. I can, however, give you my first impressions.

The first of those is that whoever in the vast Hyundai group came up with adding a long-hold function to the stereo mute button deserves a medal. By far the most annoying of the modern safety systems is the overspeed warning, which inevitably reads some signs incorrectly, others not at all, and has no idea when school zones actually start.

Thankfully, Kia, like Hyundai, now has the shortcut to mute it. You just long-hold down mute button and voila, the bing-bongs vanish.

Now elsewhere, as is pretty typical of modern Kias, the ride in this car feels properly well sorted. We've taken it through the city, onto the freeway, along a little twisting road section, and on some typically coarse and broken country B-roads, and the Sportage handled them all really well.

And even when you're getting a little frisky with the driving, there's little in the way of body roll, with the Sportage feeling planted and solid.

I wasn't totally blown away with the refinement in the cabin. On the wrong road surface, you definitely get a bit of road noise in the cabin – mind you, that is pretty hard to avoid on the coarse chip stuff – but you can also hear the engines revving away and working hard when you put your foot down.

That said, the way the gearboxes channel that power is smooth and easy, and when you put your foot down in each of the powertrains we tested, there's certainly enough urge to get you up and moving.

And that is especially true in the diesel, which I do think is a bit of a peach of a powertrain – super torquey and super easy to get the Sportage up and moving. It might find itself on the endangered species list, that engine, so get it while you can.

Now, one small downside. While the ride hasn't changed, at least for any of the ICE-powered cars, the steering has changed for all of them, and at speed, it's really lovely. It's quite direct, confidence-inspiring, and nicely weighted.

But at low speeds it can feel a little bit darty, like it takes a really big bite when you put a little input in, and it takes a little bit of getting used to.

All Sportage models start with seven airbags, and even the cheapest S gets a pretty full suite of safety stuff, including a new SOS button should you have an accident, auto emergency braking (AEB) with junction sensing, blind-spot monitoring, lane keep and lane follow assist, a rear-view camera and the often-infuriating speed limit monitoring.

From the SX+ and up you also get Kia’s Highway Driving Assist, which pairs active cruise with a lane entering function, and the GT-Line also gets remote park assist, which allows you to remotely drive into or out of tight spots, along with a blind-spot view monitor and a rear-view monitor.

The Sportage wears a five-star ANCAP rating, which it earned back in 2022.

The MU-X has a six-year/150,000km warranty and seven years of roadside assistance. That warranty is okay in terms of years, but unlimited kilometres 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 24MY and later vehicle models (up to five years/75,000km, whichever occurs first) – at a cost of $469 for each service.

All Kia models also get the brand’s seven-year, unlimited-kilometre warranty, seven years of capped-price servicing and, should you service with Kia, eight years of roadside assistance.

Turbo-petrol and hybrid models require servicing every 12 months or 10,000kms, where the rest are 15,000km intervals. The Kia website has the full costings for each powertrain choice, but for reference, seven years of hybrid ownership will cost you a not-insubstantial $4510.
