Isuzu MU-X vs Subaru Forester

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 MY26 Subaru Forester packs plenty of punch in terms of standard features, a roomy and functional interior and overall driveability. Sure, it’s not the most exciting vehicle to drive on- or off-road but to get stuck on that is to miss the point entirely. This is a decent all-rounder with a solid background and an AWD system that long ago set the gold standard for vehicles of this type.

In a tough mid-size SUV market segment aimed more at those intent on driving through car parks rather than adventuring through national parks, the Forester offers greater versatility than most and should not be ignored.

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.

This Forester is 4655mm long (with a 2670mm wheelbase), 1830mm wide and 1730mm high.

The new generation retains more than enough of the previous Forester – blocky profile included – to remain clearly recognisable.

Traditionalists may chafe at the slicker, more citified appearance of this Forester over previous generations but the overall package is inoffensive enough to not elicit any howls of outrage from passers-by on the street.

The Forester’s interior maintains a similar cabin look and feel as before but with a 11.6-inch portrait-oriented multimedia touchscreen dominating up front, a mix of physical and on-screen buttons, as well as soft-touch surfaces and durable plastics.

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 Forester is quite roomy for a mid-size SUV and this is the top-spec variant so there’s leather everywhere.

The interior layout is neat and tidy and lands firmly on the correct side of being practical and familiar, with all controls easy to locate and operate.

The touchscreen offers mostly simple intuitive functionality with infrequent need to cycle through numerous menus and sub-menus to access what you want.

The aforementioned mix of physical and on-screen buttons, as well as soft-touch surfaces and durable plastic are welcome here because, you know... real life.

The front seats offer ample support and the driver is able to dial-in their preferred position via power controls on the eight-way power-adjustable seat (with dual memory). The front passenger has an eight-way power-adjustable seat. Both seats are heated and ventilated.

The 60/40 split folding second-row seats aren’t too shabby either, in terms of comfort and amenities, with a fold-down arm-rest with cupholders and directional air vents etc.

Cargo volume is 496 litres (with rear seat in use) and 1174 litres (with the rear seat down, 1667 litres to ceiling.

The tailgate is powered and hands-free with a kick sensor (apparently). But I never tried that, instead opting for the tailgate-mounted button to open and close it.

The Forester AWD Touring (petrol) is priced at $50,990 MLP while its hybrid sibling is $55,990.

Standard features include an 11.6-inch multimedia touchscreen (with wireless Android Auto and Apple CarPlay), 18-inch alloy wheels, auto LED headlights, dual-zone climate, heated front seats and electric folding rear seats as well as a wireless phone charger.

Top-grade additions include a sunroof, low-profile roof rails, a digital driver display, leather-accented seats, a leather auto-shifter, ventilated front seats and a 10-speaker Harman Kardon audio system.

It also has power-adjustable front seats, sat-nav, auto-dipping and folding door mirrors and a hands-free tailgate.

Exterior paint choices include 'Crystal White Pearl', 'Ice Silver Metallic', 'Magnetite Grey Metallic', 'Crystal Black Silica', 'Crimson Red Pearl', 'Brilliant Bronze Metallic', 'Daybreak Blue Pearl', 'Sapphire Blue Pearl', 'Cashmere Gold Opal', 'Autumn Green Metallic' and 'River Rock Pearl'.

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 Forester has the line-up’s 2.5-litre four-cylinder naturally aspirated boxer engine (producing 136kW at 5800rpm and 247Nm at 3700rpm) matched to a constantly variable transmission (CVT), which some people detest, and some people couldn’t give a rat’s whether it’s there or not.

Also onboard is Subaru’s all-wheel drive system, driving modes (including 'Normal', 'Deep snow/Mud', and 'Snow/Dirt') and 'X-Mode' “that constantly monitors the traction available to each wheel and centralises the control of key components including the engine, transmission, drivetrain and brakes to help manage slippery conditions”, according to Subaru.

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.

Official fuel consumption on the combined (urban/extra-urban) cycle for the Forester is 7.9L/100km and it uses 91RON 'standard' unleaded petrol at a minimum.

On this test, I recorded 8.1L/100km. But fuel consumption was as low as a dash-indicated 1.7L/100km while driving the Forester with adaptive cruise control engaged.

The Forester has a 63-litre fuel tank, so, going by our on-test fuel-use figures you could reasonably expect a driving range of almost 780km from a full tank. However, as with any vehicle, once you’ve loaded the Forester with any real-world burdens (e.g kids, dogs, camping gear, etc) you’ll soon see the fuel consumption increase.

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 Forester feels comfortable and composed on sealed surfaces and offers some degree of dynamism to the driving experience – so in line with previous generations.

It feels more refined, sharper to steer and more responsive than before. There’s ample visibility to the front but a substantial B pillar obscures the driver’s vision back over their right shoulder.

The Boxer engine and CVT work well together, power and torque outputs are more than adequate in this package, and that much-maligned transmission is not intrusive if the Forester is driven with care and common sense.

However, acceleration from a full stop is sluggish.

The suspension set-up – MacPherson struts up front and double wishbones at the rear – yields a firm but not jarring sense of ride and handling.

The 1662kg Forester proved nimble to manoeuvre around the Big Smoke, the suburbs and in the bush (more about that soon) with a neat 10.8m turning circle.

All-wheel drive vehicles are capable of tackling off-road adventures in their own right but, for safety’s sake, AWD drivers should avoid anything beyond well-maintained dirt tracks in dry weather. AWD cars are designed for use on bitumen roads with some dirt or light-duty off-road use.

And so it was with our test of this Forester. On-test off-road terrain equalled firm-packed sand and gravel/dirt bush tracks in dry weather, although we did drive through one shin-deep mudhole with no trouble.

The Forester has a listed 220mm of ground clearance, the suspension held up well over a brief stint on mild corrugations and Subaru AWD proved more than up to the task when things became a little trickier, providing improved grip and traction in slippery conditions that demanded to be driven at very low speeds.

If push comes to shove, it’s capable of more than light off-roading, but the Forester’s ground clearance and off-road angles ultimately limit its off-road capabilities.

The Forester’s 'all season' tyres – Falken Ziex Z001A A/S (225/55 R18 98V) – are fine for light to moderate off-roading but anything more difficult than that and you’ll need to get a set of more aggressive all-terrain tyres. It does have a full-sized spare onboard.

It has maximum towing capacities of 750kg (unbraked trailer), 1800kg (braked) and a maximum towball download of 180kg. GVM is 2223kg; GCM is 4023kg.

Some niggles: The driver awareness system is annoyingly over-reactive.

The Forester has the maximum five-star ANCAP safety rating from testing in 2024.

It has nine airbags (dual front, dual front side, dual curtain, driver’s knee, far side and front passenger seat cushion), adaptive cruise control, emergency lane-keep and centring (with departure warnings), pre-collision braking, auto emergency steering, a 360-degree view monitor system, and a driver monitoring system which includes a ‘safe stop’ feature that – if the vehicle detects that the driver is non-responsive – will bring the vehicle to a gradual, you guessed it, safe stop.

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 MY26 Subaru range is covered by a five-year/unlimited kilometre warranty, five-year/75,000km capped price servicing, and 12 months roadside assistance.

A service is required every 12 months or 15,000km, whichever occurs soonest. After your free “1 Month Health Check and Chat”, cost per service is $347.95 (at the 15,000km/12 month mark), $520.45 (30,000km or 24 months), $393.10 (45,000km or 36 months), $679.30 (60,000km or 48 months) and $358.20 (75,000km or 60 months).
