Jeep Wrangler vs Isuzu MU-X

What's the difference?

The Overland is (surprisingly) not atrocious on-road and (not surprisingly) very capable off-road. It costs a lot but, geez, it's a barrel of laughs.

If your heart is set on a four-door mid-size 4WD that's a whole lot of fun to drive, but rather impractical for daily life, then it’s difficult to over-look the Overland.

If you’re really gung-ho about hard-core off-roading – rock-crawling etc – then perhaps you should focus on the Rubicon, but for everything else the Overland, even on standard tyres, is more than capable.

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.

The Wrangler's appearance has been tweaked throughout the years without ever sacrificing any of the ol’ Wrangler spirit.

It has stuck to its traditional roots and, as such, retains its old-school chunkiness, which is good, but the Overland is less of a hardcore-looking 4WD and more of a lifestyle-suited off-roader than its Rubicon stablemate. 

Though the Overland version has a certain blocky appeal, I reckon the Rubicon is better for having fully embraced the all-out off-road look and feel, tyres and all. 

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.

What can you say about a vehicle that has a “wash-out interior with drain plugs” listed in its specs?

This is a purpose-built off-roader and the Overland’s five-seat cabin is a basic but functional space, in which it’s easy to immediately feel comfortable. 

All dials, knobs and switches are easy to locate and chunky enough to operate while skipping over corrugations or climbing up steep rock steps.

There's leather everywhere – seats, steering wheel, shifter knob – but durable outdoors-tough surfaces also abound.

What always strikes me about the Wrangler interior is the fact that it’s abundantly clear Jeep designers regularly experience – or at least are familiar with – the type of life that Wranglers are aimed at: fun, dirty, rough-and-tumble adventures in the great outdoors.

There isn’t a lot of storage space inside but there are a few small, deep, and textured receptacles – ideal for keeping your bits and pieces in the same spot while you bounce around off-road – as well as grab handles, including a big sturdy one in front of the front-seat passenger. 

There are also tensioned net pockets on the doors so you can throw stuff in there, but beyond those there aren't a lot of storage options.

There are air vents, two USB-C ports, and a 230V inverter in the centre console.

Rear cargo space is listed at 898 litres; with the rear seat stowed away, there is a claimed 2050 litres of room.

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 Jeep has a 3.6-litre 'Pentastar' V6 engine – producing 209kW at 6400rpm and 347Nm at 4100rpm – and an eight-speed automatic transmission.

It's an effective engine-and-auto pairing for driving on sealed surfaces and well suited to high- and low-range 4WDing.

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.

Official fuel consumption is listed as 9.7L/100km on a combined cycle. 

Actual fuel consumption on this test, from pump to pump, was 13.6L/100km, largely attributable to the fact I did a lot of low-range four-wheel driving on this test, as always. 

The Wrangler Overland Unlimited has an 81-litre tank so, going by that fuel figure above, you could reasonably expect a driving range of about 595km from a full tank.

Note: Drop 30km to 50km from your total calculated fuel-range figure for a better idea of your vehicle’s safe touring range – so that figure above would be 565km.

Also, remember that numerous other factors affect your fuel consumption and so impact your touring range, including how much extra weight you have onboard (passengers, camping gear etc), whether your vehicle is fitted with any aftermarket equipment (bullbar, spare-wheel carrier, etc), whether you are towing (a camper-trailer, caravan, or boat etc), your vehicle's tyre pressures and the conditions.

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 Wrangler Overland is a fun, go-kart style drive and yields a real driver-direct experience you get from few other contemporary vehicles on the blacktop and the dirt.

But while it’s nowhere near as atrocious as you might expect on sealed surfaces its planted, squared-off stance gives it a definite composure on bitumen. It’s certainly no sports car in terms of ride and handling.

It’s quite soft on-road, soaking up most imperfections with ease, but it also takes quite a lot of effort and concentration to keep this Jeep in line on the open road because it tends to float around on the blacktop if not constantly reined in. 

Also, its steering has a lightness about it that can sometimes be a bit disconcerting. 

The V6 is a gutsy unit, capable of punching the Overland along at a fair clip, all while the eight-speed auto handles clever and nicely controlled shifts.

Because it’s so blocky, straight up and down, with big wing mirrors and the like, the Overland is rather noisy on sealed surfaces.

But it remains one of the few modern vehicles that deserves to be driven with the windows down, because it offers that kind of visceral driving experience – as the LC70 Series, or Suzuki Jimny do.

So, how does the Overland perform off-road? Bloody glad you asked.

Spoiler alert: The Overland is not as good an off-roader as the Rubicon because it does not have that variant’s BFGoodrich Mud-Terrain tyres, 'Rock-Trac' active on-demand 4x4 system (with 4:1 transfer case*, and 77.2:1 crawl ratio), front and rear locking differentials, or the Rubicon’s very handy electronic front sway bar disconnect. (* The Overland has 2.72:1.)

But, having said that, the Overland is still an extremely capable off-roader.

To be honest, I wasn't expecting any strife because it retains all the traditional goodness of the Wrangler with very few compromises. It’s a genuine 4WD with a dual-range transfer case, a ladder chassis, solid axles and well-proven 4WD heritage.

In terms of size, the Overland is 4882mm long (with a 3008mm wheelbase), 1894mm wide, 1838mm high. It has a listed kerb weight of 1900kg.

Steering has a nice weight to it at lower speeds, giving the driver a great sense of sustained control through even the most severe obstacles, but the Overland’s turning circle is a listed 12.44m, so this off-roader can sometimes feel like a mini-bus to steer through tight turns.

However, this is a purpose-built off-roader with a wide wheel track and low centre of gravity, so it feels planted no matter how rough and bumpy the terrain gets.

On the gravel track to our off-road testing site, there are numerous steering-wheel-jolting corrugations but overall the Overland – with a coil spring at each corner – soaked them up.

Our 4WD loop included the aforementioned gravel tracks, light to medium corrugations, undulating mud tracks and mud holes, and some very challenging low-range 4WD sections (in particular, a steep rocky hill), and a few other set-pieces to see if the Overland was able to do everything safely and comfortably. 

As a true 4WD worth its weight in gold, the Wrangler is immediately more at home taking on low-speed 4WDing than it is negotiating suburban traffic.

Again, the V6 engine comes into its own, delivering smooth, even torque when needed, but not ever over-working to achieve that.

Considered driving is necessary as is slow and steady throttle, but that's easily achieved in the Wrangler as its go pedal is none too sensitive to a bouncing boot.

It’s refreshing to note that switching to 4WD High or 4WD Low range is still done via a stubby stick to the left of the auto shifter, rather than the push of a button, or the turn of a dial. 

Low-range gearing is very good and the Overland has a well-calibrated off-road traction control that seamlessly launches into action when required, and wasted wheelspin is kept to an absolute minimum.

This Wrangler has 242mm ground clearance and a standard wading depth of 760mm, and was never troubled on climbing steep rock steps, traversing deep ruts or punching through mudholes.

It’s supremely sure-footed during low-range work but visibility can be an issue: over-bonnet visibility has improved slightly over previous generations but the driver’s view to the front and side is still a bit squeezed, making it at times difficult to visually pick correct wheel-placement, especially when driving steep terrain at sharp angles.

It can go hardcore, no worries, but it simply requires a bit more thought and you know what? That’s fine with me because it makes the off-roading experience an even more engaging one. 

The Overland has approach, departure and breakover angles of 35.8, 31.2 and 20.4 degrees, respectively.

With live axles front and rear, the Overland has plenty of wheel travel to keep moving and under control through truly off-grid country.

The only real compromises in the Overland’s 4x4 set-up are its standard Bridgestone Dueler (255/70R18) highway tyres and, even on those, the Overland walked up and over our toughest off-road challenges.

Though the Overland is not historically regarded as a towing platform, it’s handy for you to know that it has listed towing capacities of 750kg (unbraked trailer) and 2495kg (braked).

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 Overland Unlimited is covered by a five-year/unlimited km warranty.

Servicing is set at 12 month or 12,000km intervals at a total cost of $1995 over five years, with servicing capped at a maximum $399 per appointment.

Lifetime roadside assist is available to Overland owners when they service through Jeep.

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.
