Hyundai Santa Fe vs Isuzu MU-X

What's the difference?

The Santa Fe Hybrid is a better Santa Fe to drive than the V6 petrol or the diesel variant. It’s also a lot more fuel efficient, but the value isn’t as great at this price. Also keep in mind that the Hybrid has a much lower braked towing capacity relative to the diesel and V6 petrol Santa Fes.

The Elite grade will save you money, and you’re not missing out on many luxuries. 

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

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’s only one way to tell the hybrid version of the Santa Fe from the petrol and diesel variants - the wheels. The hybrid's wheels are smaller and have a sort of ‘cog’ design to them. I’m not a fan of the styling, but they’re supposed to be aerodynamic and save fuel.

Overall, I am a fan of the Santa Fe’s looks which were given a major change in 2020 with a completely different grille and interior.

I like the way Hyundai has moved away from giving all its cars the same face, with each model now having its own visual identity.

The Santa Fe’s wide, cat fish-like gaping mouth grille might not be for everybody, but it sure doesn’t look like the front of any other SUV on the market.

The rear of the Santa Fe is far more conservative but looks prestigious enough to stop short of the boredom threshold.

It’s far from boring inside with the dash sculptured into what appear to be rock pools, with geyser-like air vents and a floating centre console.

Again, no sign this is a hybrid in the cabin either, which is the way it should be, or will be when electric vehicles become the norm.

The cabins of the Elite and Highlander are filled with leather and modern tech. It’s a plush place made even plusher on the Highlander with its Nappa leather upholstery.

The Santa Fe is a big, mid-sized SUV at 4.8m end-to-end, but it’s not as large as a Hyundai Palisade. That's huge at five metres long.

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.

The Santa Fe is among only a handful of mid-sized SUVs offering seven seats. The third-row seats are really designed to be used occasionally. They’re flat and fairly hard and the passengers back there aren’t fully covered by the side curtain airbags.

The second row offers plenty of room. Enough, even for me at 191cm, to sit comfortably behind my driving position.

And if you’d like more space then the Highlander grade allows you can replace that bench seat with two captain’s chairs in the six-seat version.

Clever cabin storage spaces can be found throughout. I particularly like the floating centre console with an area underneath big enough for a small backpack, and the shelf above the glove box in the dash is also good for throwing a wallet or phone.  

Big door pockets, cupholders and a deep centre console storage box are also on board.

For charging devices there are five USB ports (two up front, two in the second row, and one in the third), two 12-volt outlets (front seats and cargo area) and a wireless phone charger.

While there isn’t three-zone climate control. There are directional air vents in all three rows and the Elite and Highlander grades also come with pull-up sun shades for the rear windows.

As for the boot, most of the time you’ll probably have the third-row seats folded flat, and that’ll give you a cargo capacity of 571 litres.

Or, if you are using the third row there’s 130 litres of space left for you to use.

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 Santa Fe Hybrid is not a plug-in hybrid like the Mitsubishi Outlander or Kia Sorento. That means you don’t need to connect the battery to a power outlet to charge it. Instead, the battery charges on the go as you drive it, and through regenerative braking.

Under the bonnet is a 1.6-litre, four-cylinder, turbo-petrol engine and an electric motor. They have a combined output of 169kW/350Nm.

That’s pretty good grunt. Just as a comparison, the V6 makes 200kW/331Nm, while the diesel engine produces 148kW/440Nm.

If you’re planning on towing, then the diesel and petrol are clearly the better choices with their 2500kg braked towing capacity, compared to the hybrid’s 1650kg.

The Hybrid Santa Fe is also all-wheel drive and a six-speed automatic transmission shifts gears smoothly.

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.

This is what it’s all about isn’t it? How much fuel does the Santa Fe Hybrid use? 

Hyundai says this hybrid will use 6.0L/100km after a combination of open roads and urban driving. That is excellent, but if this was a plug-in hybrid (PHEV) that figure could be as low as 4.0L/100km.

Still, the Santa Fe hybrid is much more fuel efficient than the V6 variant which uses 10.5L/100km.

I took a look at the drive history of the Santa Fe Hybrid I tested at the end of the Australian launch.

According to the trip computer the car had travelled 967.2km and had used an average of 7.3L/100km.

About 500 of those kilometres were done by me with peak hour city traffic, country roads and motorways all in there. That’s great fuel efficiency, but a Santa Fe PHEV would do better.

As I said earlier, there’s no need to plug the Santa Fe into an external power supply to charge its lithium-ion battery, it’ll charge itself automatically through normal driving.

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.

You’re not just getting better fuel economy in the hybrid version of the Santa Fe, you’re getting a better SUV to drive. 

That’s what I found when I tested the Santa Fe Hybrid at its Australian launch. The ride is more comfortable and the steering feels more responsive and lighter than the V6 petrol or diesel Santa Fe, both of which I’ve driven extensively.

The better ride I think comes down to the stabilising effect of extra weight situated low from the batteries (they’re located under the driver). Hyundai told me the front suspension had been revised to deal with the added weight, too.

So, I feel the ride is now more comfortable, less jittery with a smidge more planted feeling to the handling.

The lighter and better steering feel may have something to do with having a smaller engine in the nose of the Santa Fe. The 1.6-litre four-cylinder weighs less than the 2.2-litre diesel engine and the V6 petrol. That lighter font end now has a more ‘pointable’ feeling.

That said, the electric motor would add more weight to the Santa Fe hybrid’s nose, too.

Another difference to the way the hybrid drives is the take-off acceleration. It’s quite sudden and forceful for a family SUV in this class and that’s due to the 350Nm of torque, available from 1000rpm.

That’s great for moving away out of a car space and quickly blending into traffic, or accelerating away from traffic lights.

Visibility as with the regular Santa Fe is excellent and parking is easy, too, given this isn’t a large SUV.  

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 Santa Fe Hybrid has the same warranty as the rest of the range at five years/unlimited km. The battery is covered by an eight-year/160,000km warranty, which is pretty standard for hybrids.

Servicing is required every 10,000km/12months, however, the costs were yet to be finalised at the time of publishing.

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.
