Isuzu MU-X vs Jeep Wrangler

What's the difference?

The MU-X has plenty of appeal as a daily driver – dependable and it’s a proven 4WD wagon.

Does the 2.2-litre engine add anything substantial to the mix?

Well, it's better than the 1.9-litre, that's for sure, and there's a lot to like about this MU-X in terms of its off-road capability, driver-assist tech, standard features and all-round driveability. And, while the LS-T lacks the top-shelf polish of the X-Terrain, it’s still an appealing potential purchase.

But the 3.0-litre option is better because while the 2.2L is very effective off-road and general day-to-day driving, it lacks grunt and has to work that much harder and is that much noisier under load than the 3.0-litre in most driving scenarios, including 4WDing.

The changes to this updated Jeep Wrangler are small but meaningful. The inclusion of airbags, the updated media screen, and a feisty engine which suits the plucky nature of this off-roader make it a better Wrangler than ever.  

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

In terms of appearance, the MU-X remains largely unchanged from the most recent iteration. And that’s a good thing. It’s blocky enough to be recognisable but sleek enough to remain inoffensive. Worth noting the door handles, window trims, front fender accents, roof rails, and side steps on the LS-T are gloss black.

Inside, nothing much has changed (other than a newly-introduced idle start/stop button) and, as such, the MU-X retains a low-key familiarity that makes it a comfortable space. Generally, design-wise, the MU-X more than holds its own against the likes of the Toyota LandCruiser Prado and Ford Everest.

The Jeep Wrangler looks like a cartoon of a four-wheel drive, that’s how familiar and well-known the design is. It’s almost generic, like the word Jeep.

You could say the design is iconic, given that the roots of this SUV stretch back to the little Willys off-roader built for the US army in World War II. And to this day the slotted grille, pronounced wheel guards, short and upright windscreen, even the removable doors are still with us in this latest incarnation.

That’s why each generation of the Wrangler only sees very subtle tweaks to famous shape and look, in much the same way a Porsche 911’s design changes at the rate of dripping water reshaping a rock.

Changing the styling completely would destroy the look which connects the Wrangler to its past and the nostalgic appeal would be over. 

So, this update sees more than subtle styling changes in the form of a tweak to the grille with the addition of a metallic-look trim around each of the slots while the mesh insert now has larger openings.   

Along with this there’s a new front bumper. The Wranglers we tested had the optional heavy duty steel front bumpers.

There’s also some interior changes in the form of a new dashboard trim, horizontal air vents and then there’s the 12.3-inch media display which goes a long way to making the cabin look more modern.

Still, the interior is busy with buttons and switches in a design that seems to mix the look of heavy machinery controls with a prestige car. The Nappa leather of the Rubicon grade lifts the quality feel higher.

All Wrangler interiors also have an internal roll-over cage which covers the entire cabin, for the fixed metal roof and removable roof body style which are standard on the Overland and Rubicon.

Only the Rubicon is offered in a two-door and a four-door, while the Overland and Sport S are four-door only.

The Rubicon two-door looks cute and fun to my eyes, while the four-door versions look a bit more serious and beefy, but both definitely still give off tough and adventurous vibes.

The wheelbase difference between the two is as giant as it looks. The Rubicon two-door’s wheelbase is 2459mm while the four-door Rubicon’s, along with the Sport S and Overland, is 3008mm.

The Wrangler ranges in length from 4334mm for the Rubicon two-door to 4882mm for the four-door Wranglers. Width is the same for all Wranglers at 1894mm and the height ranges from 1879mm in the Rubicon two-door to 1901mm in the four-door versions.

The interior has a familiar and practical feel about it and the cabin is an easy space in which to become comfortable. Controls are easy to locate and operate and charging options are numerous – a mix of USB-A, USB-C (front and second row) and 12V.

Storage places include recesses for the bits and pieces from your pockets, a deep-ish 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 also cupholders either side of the third row.

The MU-X has physical-button options to activate some functions (including to switch on the audio system, to adjust volume and access sat nav).

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

My camera guru/photographer/sergeant-at-arms, Glen Sullivan, reminded me that the third-row seats don’t have ISOFIX or top-tether points for child seats. Thanks, mate.

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 stowed away.

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 MU-X’s full-size spare (bravo!) is attached to its undercarriage.

When we review most SUVs practicality is scored on things like legroom, storage space and boot size. But in the case of a vehicle with removable doors and roof, and a cabin that has one-way drainage valves so you can hose the interior out, practicality takes on a different meaning.

The Wrangler’s practicality seems focussed on serving adventurous folks in search of a muddy off-road expedition and, so, while there is storage it’s mainly nets for door pockets, moulded wells on top of the dash, and smaller hidey holes to makes sure loose items don’t get flung around the cabin.

Given the roof can be removed there’s also a lockable glove box and centre console storage box.

When it comes to cabin space the Wrangler’s interior feels a bit cramped. The footwells up front don’t offer much space and headroom throughout is restricted by the roll cage which stretches from the front to the boot.

The four-door Wrangler has five seats and good legroom in the second row, even for me at 189cm tall. As mentioned above, headroom is limited in places because of the safety structure. Boot space behind those rear seats is 898 litres.

The two-door Rubicon has four seats. The back ones aren’t the most spacious and the boot behind them is almost too small to mention at 365L, Two pieces of carry-on luggage wouldn’t fit back there and we had to put our bags on the rear seats.

The rear tailgate for all Wranglers is side-hinged (opening left to right) and splits to allow just the window section or lower part to open separately.

For charging and powering devices all Wranglers have two USB ports up front (one -A and one -C) and four USB ports in the second row (two -A and two -C). There are also two 12V outlets on board (front and rear).  

There are two cupholders, seatback map nets and directional air vents for the second row.

The Wrangler sits high and climbing into the rear seats might be a challenge for smaller kids or even fully-grown humans, but there are chunky handholds at the pillars for extra help.

So, the Wrangler has excellent practicality, but this is geared more to its intended purpose of adventuring off-road rather than the city commute and school pick-up.

The Jeep Wrangler range comes in three grades. There’s the entry-grade Sport S which can only be had with four doors, the Overland which is also a four-door and the top-of-the-range Rubicon comes as a shorter wheelbase two-door and the four-door. 

The Sport S replaces the Night Eagle as the entry-point into the Wrangler range and with a list price of $75,950 it’s $5500 cheaper, too. 

Above this is the Overland for $84,950 and at the top of the line-up is the hardcore Rubicon which is $83,950 for the two-door and $90,450 for the four-door.

This update sees all Wranglers now coming with a (damage and scratch-resistant) 'Gorilla Glass' windscreen and a 12.3-inch media screen. But each grade also comes with its own new features. 

The Sport S has been given heated front seats, a heated steering wheel and ambient cabin lighting. Meanwhile, the Overland now has power front premium 'McKinley' seats and soft spare tyre cover.

And finally the range-topping Rubicon receives Nappa leather seats and a forward-facing 'Trailcam'.

There are mechanical upgrades across the range, too, especially for the Rubicon and we’ll get to those in the engine and driving sections of this review.

As for the rest of the features, coming standard on the Sport S are LED headlights, 17-inch alloy wheels, proximity key and push button start, sat nav, Apple CarPlay and Android Auto, a nine-speaker Alpine sound system and dark tint windows.

Along with its new features the Overland also comes standard with all of the Sport S’s equipment plus a three-piece removable hardtop, 18-inch wheels and a leather-wrapped shifting knob and hand brake handle.

Then there’s the Rubicon which has all the Sport S features, but 17-inch wheels instead of the 18s and an enormous amount of engineering hardware that makes this grade the off-road king of the Wranglers, which we’ll get to.

This MU-X has a 2.2-litre, four-cylinder, turbo-diesel engine, producing 120kW at 3600rpm and 400Nm between 1600-2400rpm and it’s matched to an eight-speed automatic transmission.

Worth noting the 3.0L MU-X has a six-speed auto and produces 140kW (at 3600rpm) and 450Nm (1600-2600rpm) while the outgoing 1.9L MU-X has a six-speed auto and produces 110kW (3600rpm) and 350Nm (1800-2600rpm).

While the 3.0-litre has always been unstressed in most driving scenarios – even low-range 4WDing – the 2.2-litre feels underpowered. More about that in the ‘Driving’ section below.

The MU-X has a part-time 4WD system which includes a dual-range transfer case (with high- and low-range 4WD) and a rear diff-lock. The driver is able to shift from 2H (two-wheel drive, high-range) to 4H (4WD high-range) while on the move up to speeds of 100km/h. The diff-lock may only be engaged when the vehicle is in 4L (4WD low-range).

The MU-X also has a switchable terrain mode system which tweaks the engine, transmission and traction control to suit the driving conditions. 'Rough Terrain' mode, like a steroids-enhanced off-road traction control, is king of these modes when you’re off the bitumin.

One of the biggest changes Jeep could make to the Wrangler without causing complete mayhem for fans is to the engine and even then there will be folks who don’t like what they’re about to read.

Deep breaths, okay? Right, so, in this update the V6 petrol engine has been replaced by a 2.0-litre turbo-petrol four-cylinder. 

At 200kW the new four-cylinder makes a smidge less power than the V6 but more torque at 400Nm. An eight-speed automatic transmission shifts gears and sends the drive to all four wheels.

If you’re a Wrangler fan you’ll most likely know about this engine swap, but you’re wondering how this four-cylinder feels.

The answer is, really good. Jeep has got it right. It’s a torquey, responsive engine that feels energetic and suits the Wrangler's personality well.

In the short time I’ve spent on and off the road I’m convinced this turbo-four will be a good companion wherever you decide to go.

And go pretty much anywhere you can, with all Wranglers being ridiculously capable off-road thanks to their ladder frame chassis, high- and low-range gears, outstanding ground clearance (233mm-257mm, depending on variant ), excellent approach angle (41.4 to 44 degrees, depending on variant) and a departure angle to match (37 degrees for the both Rubicons; 36.1 for the Sport S and Overland).  

The Rubicon comes standard with Jeep’s 'Rock-Trac' on-demand four-wheel drive system and this update adds a full float rear axle. Sport S and Overland grades have Jeep’s 'Selec-Trac Active' on-demand 4WD set-up.

Official combined cycle (urban/extra-urban) fuel consumption for this MU-X is 6.7L/100km. The 1.9L MU-X offers 7.4L/100km while the 3.0L offers 7.6L/100km.

Actual fuel consumption on this test was 8.7L/100km.

The MU-X has an 80-litre fuel tank, so, going by that on-test fuel consumption figure, you should be able to get a driving range of about 920km. But remember, your fuel consumption may be completely different to mine because chances are you'll have friends, family pets, sporting equipment, camping gear, the whole kit and caboodle on board. I've only been carrying vehicle recovery gear, MaxTrax, and a first-aid kit, so I haven't had a huge amount of weight on board.

The new turbo-petrol, four-cylinder means better fuel economy than the V6 it replaces. We have yet to test Jeep’s claims that after a combination of open and urban roads the four cylinder uses 9.2L/100km in the sport S and Overland grades and 9.9L/100km in the Rubicon.

In comparison, Jeep says the previous V6 uses 10.1L/100km in the Rubicon and 9.9L/100km in the Overland. Our own testing saw consumption closer to 13L/100km.

We’ll have the new Wrangler in our garage soon and we’ll be able to put the fuel consumption claims to a real world test.

In terms of range, the two-door Rubicon has a 61-litre fuel tank and in theory a range of up to 680km. The Sport S and Overland have an 81-litre tank and can get up to 880km, while the four-door Rubicon’s 81-litre tank should manage 830km.

Of course if you’re off-roading you’ll use more fuel and the range will drop accordingly.

Before we launch into the off-roading section of this test, it’s worth noting the MU-X has always been decent on-road; composed, reasonably refined (for a 4WD wagon, anyway) and comfortable. And thankfully, with the 2.2-litre engine, not all of those characteristics have been thrown out the window.

It is quite noisy, especially under pressure when you have to do some heavy acceleration or when you have a bit of gear on board. When it has to work that bit harder than it usually does, it can become quite noisy. Admittedly, the 3.0-litre MU-X is also quite gruff, but there's an edge to the roughness in the 2.2-litre that is very noticeable on road.

This MU-X is quite sluggish off the mark, exhibiting a disconcerting lag under heavy throttle from a standing-start. And it’s far from the most dynamic vehicle to drive. But it has a tractability about it that manages to mostly negate these flaws.

Otherwise, the new eight-speed auto deserves credit as it’s slick and smooth in application and feels right at home in this wagon.

Now to off-roading. The MU-X is still very capable. In fact, even with the 2.2-litre engine, it remains one of the better-performing 4WD wagons straight out of the dealership, in terms of pure off-road capability.

The 3.0-litre MU-X is not the torquiest in this segment, but it offers ample pulling power available across a wide rev range – count on peak torque between 1600rpm and 2400rpm – and it delivers that pulling power in an even-handed fashion. The 2.2-litre MU-X has to work harder than its stablemate, and it’s noisier and harsher.

However, those characteristics don’t take away from how effective this MU-X is because it offers impressive off-road performance. It still has a decent amount of low- and mid-range torque, which makes dirt-road cruising and low-speed 4WDing easy.

The MU-X has part-time 4WD with high- and low-range 4WD gearing, a rear diff lock and overall it retains all of that off-road capability the 3.0-litre MU-X has been renowned for – so you don't lose any efficacy there.

The line-up’s off-road traction control system, which once was a bit patchy in its effectiveness, has gone through a couple of phases and it’s been recalibrated/tweaked over the years and it is much better now.

Of course, the MU-X also has Isuzu’s much-vaunted Rough Terrain mode (a form of early-acting off-road traction control which converts lost grip into torque for the wheels with grip), and it is smooth and effective, giving the driver better overall control in challenging terrain.

Some of this MU-X’s listed off-road angles appear shallower than the 3.0-litre MU-X’s – approach: 23.9 (3.0L = 29.2), departure: 26.4 (3.0L = 26.4) and ramp-over: 19.6 (3.0L = 23.1) – but, even if that is the case, it has very similar driving characteristics in low-speed, low-range four-wheel driving to its 3.0-litre stablemate.

If you drive with control and consideration, you shouldn't have any trouble tackling light to moderate 4WDing in this MU-X. It could even, if push comes to shove, handle challenges that may be considered by some to be on the edge of hard-core 4WDing – for a showroom-standard 4WD wagon anyway.

Ground clearance is 235mm and wading depth is 800mm, so there’s an adequate amount of clearance to work.

The MU-X – with a turning circle of 11.6m and a kerb weight of 2130kg (3.0L = 2185kg) – feels quite nimble on bush tracks.

This wagon’s wheel travel – how far the axle can move up and down relative to the chassis – has more than an adequate amount of flex, stretching its tyres close, if not all the way, to the dirt.

A noticeable trade-off is its 20-inch wheel-and-tyre combination, which is best suited to sealed surfaces and so are far from ideal for dirt-track touring. There’s an easy remedy, though. Buy a set of decent all-terrain tyres on 17- or 18-inch rims to replace the showroom-standard 265/50R20 Highway-Terrain tyres. If you are using your MU-X, avoid dropping pressures too much because you’ll risk sidewall pinches and punctures on these low-profile road tyres.

In terms of packability: the 2.2L MU-X has a listed payload of 670kg, whereas the 3.0L version offers 615kg.

The 2.2L MU-X can legally tow 750kg (unbraked trailer) and 3500kg (braked), so theoretically you can tow the same load as a 3.0-litre MU-X. But, as mentioned, the 2.2-litre engine feels underpowered, even in general day-to-day driving, so with a load and/or towing that’s an added burden.

For reference, the 2.2L MU-X has a listed gross vehicle mass of 2800kg and gross combined mass of 5900kg.

Every one of the Jeep launches I’ve attended over the past 15 years has involved a pretty decent off-road component and it’s clear the company has a lot of faith in its product.

This Wrangler launch’s off-road test had been scaled back due to days of flooding rain beforehand, but the section that was passable was enough to remind us of what we already know and that is the Wrangler is formidable.

A Queensland bush off-road course full of steep, muddy hills, ruts, rocks, dirt and slippery descents was still all there for us to test the Wrangler Rubicon four-door.

Fun and comfortable are the first words that pop into my head when recalling how the Rubicon fares. This is a super-capable beastie that feels planted, secure and adept at all times.

We tested low- and high-range four-wheel drive, locked the rear differential and let the hill descent mode do its thing and get us down the sides of hills that felt so close to vertical all we could see through the windscreen was the ground.

What's also clear is the new turbo-petrol, four-cylinder feels well suited to the job, with plenty of torque along with a feisty and responsive nature that fits the Wrangler better than the old V6.

There was also plenty of time spent on the road in the four-door Rubicon and its smaller two-door sibling. And was here it was also super clear the Wrangler felt like we’d taken it out of its natural habitat.

At 110km/h on the motorway the two door Rubicon feels light and floaty in its suspension, with steering adjustments having to be made constantly, like actors pretending to drive cars in movies, as the Wrangler wanders around in its lane. The Wrangler wander is a known trait and isn’t specific to this updated car. 

And even though our launch drive took us on some great winding country roads which would have been perfect for a Mazda MX-5, the Wranglers found the fast tight turns difficult to handle.

I’m sure I heard a sigh of relief from our Rubicon as we pulled off the road and selected low-range four-wheel drive before bouncing up what looked to be a sheer cliff, with ease.  

Of course, our Adventure Expert Marcus 'Crafty' Craft will put the Wrangler though its paces once we have one in the CarsGuide garage.

The Jeep Wrangler has a three-out-of-five star ANCAP rating from testing in 2019. This isn’t an adequate safety score for a modern vehicle and the relatively modest advanced safety tech compared to other new SUVs and its structural integrity in crash tests caused ANCAP enough concern to award it lower scores.

Surprisingly the ANCAP report scored its child occupant protection at 80 per cent which is excellent.

This update to the Wrangler now adds curtain airbags which cover the front and second rows. Along with these there are dual front airbags plus safety tech which includes AEB (city and inter-urban) and blind spot warning. There’s also adaptive cruise control and front and rear parking sensors.

For child seats you’ll find two ISOFIX and three top tether mounts across the second row of the four-door variants.

The standard full-sized spare wheel is mounted on the tailgate. 

The MU-X has a six-year/150,000km warranty and seven years of roadside assistance. Unlimited km in the warranty 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 MY24 and later vehicle models (up to 5 years/75,000km – whichever occurs first) – at a flat price of $469 for each service.

Isuzu Ute Australia has a nationwide network of more than 160 dealer sites.

The Wrangler is covered by Jeep's five-year/100,000km warranty, which is off the mainstream market standard of five years/unlimited km.

Service intervals are recommended every 12 months and 12,000km and service prices are capped at $399. Jeep also offers lifetime roadside assistance if you service your Wrangler though Jeep.
