Isuzu MU-X vs Subaru Outback

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 Subaru Outback Sport Touring XT is what you get when you want a beefed-up station wagon masquerading as an SUV that can handle adventuring and haul the family around in comfort. The limited edition has all of the great features you'd expect from a top model and a reasonable price tag but its fuel thirst will turn some people off.

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 Sport Touring XT model is only available in the exclusive Geyser Blue paintwork (you'll either love it or hate it), has green accents scattered across the body and sports sharply styled and dark 18-inch alloy wheels.

The rear gets black badging and a spoiler but the black plastic moulding that Subaru is well known for is well and truly present.

There are some small design differences between the limited edition and it's siblings but at the end of the day it looks like an Outback.

Head inside and you'll find a solid and well-built cabin. The dashboard features a flashy 11.6-inch tech screen but the instrument cluster is still mostly analogue with a small 4.2-inch screen.

There are heaps of buttons and dials to play with and you also get a proper gear-shifter. The design will make this a winner for folks who want a car to look like a car, with its controls where they expect them to be.

Overall, the cabin feels premium but isn't fussy.

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.

The cabin of the Outback has always been practical but the premium features this grade comes with ensures proper comfort for all occupants.

Seat comfort is high with the powered front seats that have heat and ventilation functions but the driver benefits the most with the extendable lumbar- and under-thigh supports.

The rear row is almost as comfortable as the front where passengers feel secured by the padded side bolsters, while taller occupants will love the head and legroom on offer. The heat function for the outboards is appreciated and the directional air vents are easy to position.

The 213mm ground clearance means it's easy getting in and out of the model but access to the back row is a little annoying. The footwell lip sits high and catches unsuspecting feet but it's the doors that made my eight-year-old grumble this week because they're heavy to operate.

Storage up front isn't class-leading but you get a glovebox that fits a manual, a dual-opening middle console, two cupholders and drink bottle holders, as well as a sunglasses holder and small cubby in front of the gear-shifter (which is annoying to access).

Storage is much better in the rear with four map pockets, storage bins in each door, two cupholders and two drink bottle holders to choose from.

The boot has 522 litres of capacity available, which is plenty of room for a road trip or a big grocery haul and the level loading space makes it easy to slide things in and out. You get a proper full-size spare tyre, which is rare nowadays and the powered tailgate is always a handy feature.

Technology feels well rounded and the touchscreen multimedia system is responsive and easy to use. However, the portrait position makes the icons and text on the wireless Apple CarPlay look small and I may have made a few accidental calls this week because of it.

The satellite navigation is easy to use and there's also wireless Android Auto. Charging options are decent with each row getting a single USB-A and C port but the front misses out on a wireless charging pad.

There are usually five variants available for the Subaru Outback but the model on test for this review is a special edition that blends the qualities and features of the top Touring XT but with some exclusive design changes.

Did we need it? Probably not but Subaru has wisely kept the price increase to a minimum, so the AWD Sport Touring XT is $57,490 before on-road costs, just $500 dearer than the usual top grade.

Despite looking more like a station wagon, the Outback sits in the large SUV segment and when it comes to an 'apples to apple' comparison, there's nothing really to compare it to.

With that in mind, the Skoda Superb Sportline wagon costs $74,990 drive-away, and a more traditional SUV like the Volkswagen Tiguan Allspace 162TSI R-Line is priced from $60,590 MSRP.

The standard premium equipment for the Sport Touring XT model includes Nappa leather upholstery, eight-way powered front seats with the driver enjoying additional lumbar and under-thigh support, as well as two-position memory function.

Also included are heating and ventilation functions for the front seats, heat function for the rear outboard seats, a heated steering wheel and sunroof with manual blind.

Technology is well-rounded with an 11.6-inch touchscreen multimedia system with satellite navigation, dual climate control, wireless Apple CarPlay and Android Auto, digital radio, AM/FM radio, two USB-A ports, two USB-C ports, two 12-volt sockets, and a nine-speaker Harman Kardon sound system.

Practical features include dusk-sensing LED headlights, rain-sensing windscreen wipers, keyless entry/ start, a full-size spare tyre and hands-free powered tailgate.

The limited-edition model is well-specified and while it lacks the extra two-seats that its rivals have, it still offers solid value.

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.

The Sport Touring XT gets a 2.4L four-cylinder turbo-petrol boxer engine that produces a hefty 183kW of power and 350Nm of torque.

The re-tuned continuously variable transmission (CVT) system feels like it is changing gears but it's smooth and punctual, no matter the speed.

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.

Unfortunately, the turbo-petrol engine is thirsty and the official combined fuel cycle figure is 9.0L/100km.

With its 63L fuel tank, you have a theoretical driving range of up to 700km, which is best-case scenario but expect less range if you’re a city dweller.

After doing a mix of open road and city driving this week, my real-world usage came out at 9.3L, which is better than I expected.

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.

The Sport Touring XT model is nice to drive. The best word to describe the on-road experience is ‘smooth’.

Power delivery is prompt and getting up to speed feels effortless. It's a great open roader but also feels spritely in the city.

The ride comfort is excellent and it’s only when you hit the highway that the wind noise starts to creep up, otherwise, the cabin is quiet and you can chat with back passengers without raising your voice.

The higher ride doesn’t translate to a bumpy suspension and while you’re aware of the road, you’re never bothered by it.

The steering is on the right side of firm for it to feel agile and competent no matter what you’re throwing at it. Visibility is also pretty good but the headrests in the back seat, when up, can hinder your rear-view vision.

The Outback sits at 4870mm long and 1875mm wide, so it fills out a car space but the higher ground clearance means you’re not worried about scraping on ramps and it’s relatively easy to park.

However, it feels cheeky to not have a 360-degree view camera system at this grade level. The reversing camera it comes with is sufficient, but you miss out on front parking sensors.

The Outback has a maximum five-star ANCAP safety rating from testing done in 2021 and features eight airbags which includes a front centre airbag.

It also scored highly across its individual assessment scores with ANCAP. It got 88 per cent for adult protection, 91 per cent for child protection, 84 per cent for vulnerable road users, and 96 per cent for its safety assist systems.

Standard safety equipment includes blind-spot monitoring, tyre pressure monitoring, LED daytime running lights, rear and forward collision warning, rear cross-traffic alert, lane departure alert, lane keeping aid, emergency lane keeping aid, emergency autonomous steering, lead vehicle start alert, traffic sign recognition, adaptive cruise control, reversing camera and front parking sensors.

The driver monitoring system has been improved from previous models and while still sensitive, it no longer chimes at you all the time, which is a welcomed change.

The Outback has two ISOFIX child seat mounts and three top-tether anchor points. The rear seat is wide enough to accommodate three child seats if they're not too large.

The auto emergency braking (AEB) has car, pedestrian, cyclist and back-over detection and is operational from 1.0 to 160km/h but it's usual to see this system operate from 5.0km/h, which is excellent.

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.

Subaru offers the Sport Touring XT model with a five-year/unlimited kilometre warranty but it’s becoming more common to see longer warranty periods being offered now.

You can pre-purchase a three- or five-year servicing program and the three-year program costs $1406.57 (average of $469).

The five-year option costs $2646.17 (average $529 per service) which is reasonable for the class.

Servicing intervals are good at every 12 months or 15,000km, whichever occurs first.
