Kia Sportage vs Isuzu MU-X

What's the difference?

Kia has upped its game with the new Sportage, especially in this circa-$50,000 part of the segment. It is absolutely packed with comfort, tech and safety features and it’s hard to beat when it comes to value. The fact that it offers such an engaging drive experience is a bonus, and a credit to the local team. Look out Mazda CX-5 and Toyota RAV4, the new-gen Sportage may just be the new dynamic pick of the segment.

So, engine aside, not much new for the 2024 MU-X, but I can confidently say this: if you’re not towing big loads all of the time, then the 1.9-litre turbo-diesel won’t just save you cash at the dealership, but at the service station, too.

There sure is. Kia has been known for strong design for some time now, thanks in large part to a brand transformation led by former Audi designer Peter Schreyer a little over a decade ago.

The third-generation Sportage from 2010 was a game-changer for Kia, with its modern design helping elevate the brand in Australia. The fourth-gen version from 2015 built on that with a much sharper take on Kia’s design language, but the latest model takes it to a whole new level.

Based on Kia’s new 'Opposites United' design language, the new Sportage is undeniably modern, almost radically so, and it makes many of its rivals look staid. To say the Sportage received a lot of attention during our week driving it would be an understatement.

The boldest design elements are up front. The gloss black grille graphic introduces a new take on Kia’s signature ‘tiger nose’ grille, which is surrounded by very cool boomerang-shaped LED daytime running lights that hug the LED headlights.

A darkened D-pillar treatment, bulging rear shoulder line, appealing LED tail-light design, rear tailgate spoiler and sexy 19-inch machined alloy wheels cap off the Sportage’s striking look.

If you like the look of the 2023 Isuzu MU-X, then boy have I got good news for you, because the changes to the 2024 model occur under the bonnet, and nowhere else, really. That means you get the same simple, boxy exterior design, which emphasises capability over fanciness.

Yes, the MU-X design is more dependable than daring, but I reckon it works, with the three-row SUV cutting a fairly handsome figure, even if it is yet to receive the design tweaks just rolled out on the updated Isuzu D-Max.

Inside, though, it definitely presents as a little utilitarian, with some plastics that feel like they could survive a nuclear blast, and the 7.0- and 9.0-inch central screens both feel a little underwhelming by modern standards.

It all feels very comfortable and hard-wearing though, which is probably every bit as important, given the MU-X’s target market.

Kia has been kicking serious goals lately when it comes to interior design, comfort and materials. The Sorento is a stellar example of thoughtful and appealing design. Thankfully, the Sportage follows suit.

As is often the case, particularly with Kia and sister brand Hyundai, the higher grades make the entry-level models look like stripped out, bargain basement offerings.

While the Sportage GT-Line has high-end fittings and a massive connected screen, the base Sportage S has none of the fancy tech, a budget screen and it’s missing armrests and more.

However, we are assessing the GT-Line so best to compare with similar rivals.

There’s a lot to like in the cabin, from the soft-touch materials on the dash, to the gloss black and lovely grey woodgrain inserts. There’s no mistaking this for anything but the top-spec model.

Thank goodness for the digital air con controls that sit between the screen and console. You don’t have to fumble through a menu on a screen like some models.

The nicely laid out centre console houses a drive mode selector, seat heating and cooling controls, gear dial (don’t love) two sizeable cup holders you can convert into one big space, and a gear shifter dial instead of the lever found in lower grades.

Kia’s well-designed three-spoke leather-appointed steering wheel houses clear controls and it feels nice to touch.

Cool retro-looking air vents sit on either side of the main screen, which is curved. Actually, it’s two 12.3-inch screens side by side, seamlessly integrated. It’s an interesting approach from Kia, and it works.

The instruments are clear and configurable to show different vehicle information, but it lacks a head-up display. Kia might think it doesn’t require one, but it wouldn’t go astray.

Kia’s multimedia system is a winner. It’s intuitive, simple to navigate and the graphics and icons are modern and visually appealing. Every single one of Kia’s Japanese rivals, except maybe Mazda, take note.

Connecting the phone to Bluetooth is quick and easy and there were no connection issues with the wired Apple CarPlay. Hopefully Kia and Hyundai add wireless CarPlay to higher grade models soon. Many entry grades have the wireless set-up.

Storage-wise a phone fits neatly in to the wireless charging slot that has a sliding cover, and the central bin has enough room but it’s not huge. Same goes for the glove box.

Door bottle storage is tight up front and we couldn’t get thicker bottles in there.

The perforated leather-appointed front seats with synthetic suede look lovely and offer great upper body support, but could to with more under-thigh bolstering. Regardless, they are very comfortable.

Kia has stretched the new Sportage by 175mm in length compared to the old one, which has added 80mm to the wheelbase, and it shows. The second row is so much more spacious than the model it replaced. There’s plenty of toe, knee and legroom and the panoramic sunroof has no impact on headroom back there, even for my six-foot (183cm) frame.

Conveniences back there include lower air vents, two USB-C ports on the rear of the front seats, map pockets on both sides, a storage nook under the vents, a coat hanger hook on the seat backs and a very handy slot for a phone or tablet in the back of the front headrests. Oddly, bottles slot in to the doors more easily in the rear.

Rear seats have some upper body bucketing and are quite comfortable. The centre armrest folds down with two cupholders and the backrests recline. The 60/40 seats can be lowered easily via levers in the boot and they fold close to flat.

It has a full-sized spare wheel under the boot floor and shopping back hooks. With the rear seats up it can swallow 543 litres – more than the old one – and 1829L with the second row stowed. That’s more than the new Mitsubishi Outlander and slightly more than the Toyota RAV4.

Practicality has always been a sizeable MU-X perk, regardless of the engine. 

That starts with seven seats, and a back row where actual full-size humans can spend time — and there are not many three-row SUVs you can say that about.

I’m 175cm tall and while I wouldn’t pick row three as my first choice, I’d happily sit back there for short hops.

The middle row, too, is pretty spacious, though it is lacking in a few creature comforts, with just the air-con vents (but no temp controls) and a couple of USB ports to keep you company.

And remember when I said the brand was promising the 1.9-litre engine wouldn’t cost much in terms of capability? Well, Isuzu says the braked towing capacity for models fitted with the smaller engine is 3000kg, while the payload figure increases — now up to 735kg — mostly because the new engine is about 70 kilos lighter. Models fitted with the 3.0-litre turbo-diesel are still rated to tow 3.5-tonne. 

The MU-X stretches 4850mm in length, 1870mm in width and 1815mm in height and it sits on a 2855mm wheelbase, which means while there’s plenty of cabin space it’s not too ridiculous to park.

You’ll find 311 litres of boot space with all three rows in place, growing to 1119 litres with the second row folded flat and 2138 litres with just the front two seats in action.

Every MU-X model will offer at least 800mm in wading depth and 230mm ground clearance, too.

It has always been a value-packed proposition, the MU-X, and nothing much has changed for 2024, especially if you’re shopping for the smaller engine option. Be warned, though, there are price jumps for the carryover 3.0-litre turbo-diesel in most grades.

As usual in the ute-based SUV space, the complexity of trims and powertrains can be a little confusing, but the short version is the MU-X can be had in three trim levels, with the 1.9-litre engine offered on two of them, the LS-M and LS-U.

The LS-M opens proceedings with 17-inch alloy wheels, LED headlights, black sidesteps, keyless entry, cloth trim inside, a 7.0-inch central screen with Apple CarPlay and Android Auto and air-conditioning.

The LS-U then adds 18-inch alloys, roof rails, a leather steering wheel, a bigger 9.0-inch central screen, dual-zone climate control and a powered tailgate.

Finally, the flagship LS-T gets 20-inch alloys, leather seats that are heated in the front and remote engine start. 

All 4x4 models are plenty capable, too, with '4x4 Terrain Command', '2-High', '4-High' and '4-Low', a rear-diff lock and a 'Rough Terrain' mode which helps with grip and traction on slippery surfaces.

This Sportage GT-Line is powered by a 2.0-litre four-cylinder turbocharged diesel engine pumping out 137kW of power at 4000rpm and 416Nm of torque at 2000-2750rpm.

In terms of outputs, it matches its mechanical twin, the Tucson, and it’s roughly in line with the VW Tiguan (147kW/400Nm), but it’s slightly down on the Mazda CX-5 2.2-litre diesel’s 140kW/450Nm.

All diesel Sportage grades come with all-wheel drive as standard and the transmission is an eight-speed automatic.

Let’s focus on the new engine option here, with the 1.9-litre turbo-diesel delivering 110kW and 350Nm. They don’t sound like massive numbers, but Isuzu makes the point that the torque delivery is wide, with maximum grunt available from 1800rpm to 2600rpm, and 300Nm available from 1550rpm to 3700rpm, meaning there’s power there when you need it.

The new engine pairs with a six-speed Aisin tramsission and delivers power to two or all four wheels.

According to Kia’s figures, the Sportage diesel consumes 6.3 litres per 100 kilometres on the combined cycle.

We ended our week of testing with 8.9L/100km, which is considerably more than the official claim. Granted, it was a week of very mixed driving – freeway, heavy traffic, inner city and back road testing – so you’d likely get better results in a less erratic week.

The Sportage emits 163g/km of CO2 and has a 54-litre fuel tank.

Another perk of the smaller engine is a smaller fuel bill, with the 1.9-litre turbo-diesel promising to drink 7.4L/100km on the combined cycle - almost a litre less than the 3.0-litre 4x4 model, which is more like 8.3L/100km. 

Emissions drop, too, with the smaller engine rated at 196g/km of C02 combined, compared with 220g/km on for the 3.0-litre 4x4 model.

Impact on the hip pocket? Well, fewer trips to the service station for one. Isuzu says the 80-litre fuel tank should deliver almost 1100km of driving between refills.

There wasn’t anything particularly wrong with the previous Sportage, but it was middle of the pack when it came to dynamics and overall driver engagement.

While I can only speak for the flagship GT-Line diesel here, it’s safe to say the new model represents a big improvement over the outgoing car.

Quite conveniently, I spent the week prior to the Sportage with the Hyundai Tucson Highlander diesel – the direct equivalent to the Sportage tested here.

While I found very little wrong with the Tucson, it lacked a level of driver engagement that gives a car that fun factor.

Despite the two models sharing so much of their underpinnings, the Kia manages to offer that playful dynamism lacking in the Tucson.

To start, the turbo-diesel engine is more responsive in the Sportage, even though the two have identical outputs. There’s a hint of turbo lag, but the Kia delivers its power and torque in a more linear manner.

This responsiveness comes in handy during daily driving around town, but it’s also useful if you need to overtake on a highway.

Steering is heavy even at low speeds and it feels like it pulls back to centre when turning. It could be a little looser on that front, but it’s direct when required.

One of the reasons for the more engaging driving characteristics is Kia’s local ride and handling program. The Sportage has been tuned by locals for local conditions and the team generally does an exceptional job.

The Tucson didn’t get the usual rigorous local tune from Hyundai’s specialists and that’s given the Sportage the edge.

It feels more planted to the road and given its GT-Line badge, it’s been tuned for more enthusiastic driving.

The Sportage doesn't skip on loose edges, even when cornering, and it remains remarkably flat through the twisty stuff.

The eight-speed auto does a good job for the most part, shifting smoothly, but it occasionally hunts for gears when the engine is pushed hard.

The ride quality also impresses. The Sportage is not bothered by speed bumps in urban areas or potholes. The 235/55 R19 tyres have a decent sidewall and help soak up these bumps.

Despite some noticeable road and tyre noise on coarse chip roads, the cabin has a good level of insulation and is generally hushed. The diesel isn’t as agricultural as some, too, so that helps with noise levels. And there was no vibration detected through the steering wheel.

One gripe is that the auto wipers are all but useless. Even when they are on the highest auto setting, they just don’t seem to detect the rain and you have to engage it manually.

First things first, you can absolutely tow with the smaller MU-X engine. In fact, we attached a load weighing close to its 3.0-tonne maximum and the Isuzu just hunkered down and got to work.

It must be said, though, it’s nowhere near as effortless as when you have the bigger 3.0-litre turbo-diesel engine up front, which dispatches heavy loads clinically and easily.

The smaller option has to try harder and rev higher, and while it’s easy enough on downhill runs or flats, it’s noticeably slower when heading up hill.

It does demand the question of how often you’ll be attaching close to its rated maximum on the towball, though. If it’s often, the bigger engine is definitely for you. But if it’s occasionally, or your tow loads are lighter, you can definitely make do with the 1.9-litre option.

On the road, the 1.9-litre engine’s power delivery is actually pretty well suited to the MU-X. It’s not fast, of course, but the width of the torque band helps deliver grunt when you need it (to a point) especially in the low-end, and I reckon the whole experience is a bit smoother and quieter than with the bigger engine, too.

You are missing some of that effortless grunt, of course, and you still can’t escape the usual diesel noise that permeates the cabin, but the lower fuel use for lower power feels like a fairly decent trade. 

It won’t be for everyone, and cross-country travellers and towers will no doubt go for the bigger unit, but for everyone else the 1.9-litre is a pretty sensible option.

Full credit to Isuzu here for fitting every MU-X model, including the cheapest option, with its full safety kit, which starts with eight airbags in the cabin. 

From there, the active stuff kicks in, with the MU-X featuring AEB, 'Forward Collision Warning', adaptive cruise control (with 'Stop and Go'), traffic sign recognition, lane departure warning, 'Lane Departure Prevention', lane keeping assist, 'Emergency Lane Keeping', blind spot monitoring, rear cross-traffic alert and 'Trailer Sway Control'.

The MU-X has a maximum five-star ANCAP score from testing in 2022.

The Sportage comes with Kia’s seven-year/unlimited kilometre factory warranty, and free roadside assistance for one year.

It’s also covered by a seven-year capped-price servicing program that will cost approximately $3500 over the seven-year period. Service intervals are every 12 months or 15,000km.

Every Isuzu MU-X model gets a six-year, 150,000km warranty, as well as five years of capped price servicing, and up two seven years of roadside assistant. 

The service are 12 months or 15,000km, and each service costs $449 per year, or a total $2245 over five years.
