Kia Seltos vs Isuzu MU-X

What's the difference?

Kia’s updated Seltos is more expensive than the previous version but it's better as well.

The entry grade no longer has hubcaps and gets alloy wheels, all grades have directional air vents in the second row, the jerky dual-clutch auto is gone and an excellent regular eight-speed auto has arrived, plus there’s more safety tech and modern displays screens.

What hasn’t changed is the Seltos’s size. It’s a big, small SUV, that’s easy to park in tight spaces but roomy inside even for tall, awkward humans like me. 

The sweet spot in the range is the Sport+ with the 1.6-litre engine, if only it had the LED headlights that only come on the GT-Line.

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.

This updated Seltos has had a few styling tweaks, too. The grille is taller and  there’s a new headlight design which on the GT-Line is stunning with its LED running lights.

The rear of the Seltos has been restyled as well, with a new tail-light design and again on the GT-Line there’s an LED strip which runs between them.

The Seltos is pretty big for a small SUV. At 4.4m long it’s bigger than a Hyundai Kona and a Honda HR-V and about the same size as a Nissan Qashqai and Corolla Cross.

What’s good about that is you’re getting more space inside with a package that’s still smallish on the outside.

If you think the Seltos’ look is familiar, then I agree. The Honda HR-V and Haval Jolion have very similar tail-light designs and the profile follows many of the same styling cues of the Toyota Corolla Cross.

To my eyes, though, I think the Seltos is the more refined looking of its peers with a more modern and interesting interior.

Speaking of which, keep in mind that the top-of-the-range GT-Line’s cabin is far more fancy than the interior of the entry grade S. The GT-line’s large double digital displays are impressive and the buttons around the shifter for seat heating and ventilation are replaced with blank plastic panels in the S. 

Hard plastic armrests were another of my gripes about the previous entry grade Seltos, too.

Still all cabins have a premium look even if the feel isn’t luxurious throughout on all grades. 

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.

Some small SUVs are seriously small, which might be fine for some, but if you’re hoping to also have enough space for passengers in the back seats, and a boot which can carry plenty of luggage then the Seltos is a good choice.

Even at 191cm tall I had more than enough room to sit behind my driving position with good headroom back there, too.

Cabin storage is also good with door pockets front and rear, and a deep centre console box. As for cupholders there are two up front on all grades, while the Sport+ and GT-Line get two more in the second row fold-down armrest.

Boot capacity depends on if you’ve requested a full-sized spare wheel or the space-saver spare. With the space-saver you’ll have more room at 469 litres, while the full-sized wheel under the boot floor will leave you with 433 litres. That’s still decent for the class.

The new Seltos has directional air vents for back seat passengers which is a win (motoring journalists had been complaining about the lack of them for years) and there are also two USB ports (Type-C) for the second row along with another two for those in the front, plus a 12V outlet.

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.

The Seltos range has two engines to choose from: a 2.0-litre four-cylinder petrol engine making 110kW/180Nm and a 1.6-litre turbo-petrol engine producing even more grunt at 146kW/265Nm.

The 2.0-litre engine comes with a CVT which is a type of automatic transmission and the 1.6-litre engine has an eight-speed auto.

CVT stands for Continuously Variable Transmission and some people (me included) find the droning they cause the engine to make to be annoying. They also come with a feeling of less acceleration. 

The good news is the eight-speed auto that comes with the 1.6-litre is a great transmission with smooth shifts and a sporty nature that matches the punchy engine. 

This eight-speed auto is welcome because it also replaces the jerky dual-clutch transmission that had been paired with the 1.6-litre engine in the previous Seltos.   

All-wheel drive is only available with the 1.6-litre engine while front-wheel drive comes solely with the 2.0-litre.

So, if you’re after great acceleration and better traction then the 1.6-litre is the way to go. If you’re not after a sporty driving experience then the 2.0-litre engine will suit you, and it costs less.

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.

The smaller engine actually uses more fuel, but not a great deal more. Kia says the 1.6-litre engine with all-wheel drive uses 7.4L/100km after a combination of open and urban roads. The 2.0-litre engine according to Kia will use half a litre less at 6.9L/100km.  

Both engines only need 'standard' 91 RON petrol, too - that’s the cheap one.

Where is the hybrid variant? Good question. The answer is, there isn’t one. And neither is one coming, I’ve asked. That’s disappointing considering the Corolla Cross comes with a hybrid version of each grade in its line-up.

It’s for this reason the Seltos range scores a lower mark for fuel efficiency.

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.

The Kia Seltos has two personalities. The laid back Seltos with a 2.0-litre engine and the enthusiastic sporty Seltos with the 1.6-litre engine.

Regardless of which Seltos you pick, the ride is comfortable, the handling is good, and the steering is excellent. 

Kia says it's worked to make the Seltos’s cabin more insulated from road noise, but having driven it on country roads for hours I think it could do with more sound dampening.

If you’re considering the Sport+ grade and are not sure if the $3500 premium for the 1.6-litre engine is worth it, my answer would be absolutely, if you can afford it.

That 1.6-litre turbo petrol is a great engine and the new eight-speed transmission is excellent. Even as a daily driver I think anybody would enjoy driving this version of the Seltos more, and for those who like sporty driving then it’s definitely the powerplant for you.

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 Seltos is covered by Kia’s seven-year, unlimited-kilometre warranty. 

Servicing differs between the two engines.

A Seltos with a 1.6-litre engine needs to be serviced every 12 months or 10,000km and over seven years the average service cost comes to $497 per year.

A Seltos with the 2.0-litre engine needs to be serviced every 12 months or 15,000km and over seven years the average service costs comes to $434 per year.

Capped price servicing is good, but the prices can get higher than $600 for some visits.

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.
