Isuzu MU-X vs Toyota Fortuner

What's the difference?

The MU-X has always had plenty of appeal as a daily driver – dependable, not dynamic – and it’s a proven 4WD wagon.

Some people don't like the noisy, sluggish engine, but I don't mind it because it delivers off-road.

There was already a lot to like about the seven-seater wagon in terms of its off-road capability, driver-assist tech, standard features, and simple all-round driveability, and the X-Terrain – which encompasses all of that AND adds some polish to the mix – is an impressive top-shelf addition to the MU-X line-up. Even if it's so pricey...

The Toyota Fortuner is a family friendly wagon and a very capable 4WD, but it’s looking and feeling decidedly old, especially when cross-shopped against the current highly competitive 4WD wagon market in which vehicles are increasingly stylish, sophisticated and packed with driver-assist tech (that isn't clunky) and standard features (that are extensive).

The Fortuner is practical and easy to live with as a daily driver, and in GXL spec it makes a lot of sense as a functional not flashy off-road tourer, but it’s far from the best family 4WD wagon around.

Until a next-generation Fortuner possibly arrives, there are plenty of Toyota fans who’d happily settle for a current Fortuner – if they haven’t already.

As I’ve said before, the MU-X has never been particularly exciting or boring in terms of design, just comfortably adopting a low-key, middle-of-the-road type design – sales gold, in other words.

But the X-Terrain has distinctive ‘X’ branding here and there – inside and out – and that adds a subtle class to this variant.

The X-Terrain is 4860mm long (with a 2855mm wheelbase), 1870mm wide (excluding mirrors), 1825mm high and has a listed kerb weight of 2195kg.

It has a wheel track of 1570mm and an 11.6m turning circle. 

Our test vehicle has the exclusive X-Terrain paint – slate grey metallic – which matches well with the X badging, bigger grille design, new headlights, three-tier LED tail-lights, and redesigned wheels.

The interior strikes a stylish note as well with red stitching on the dash, centre console and leather-accented seat trim.

The GXL is 4795mm long with a 2745mm wheelbase. It is 1855mm wide, 1835mm high and has a listed kerb weight of 2185kg. It has a 11.6m turning circle.

Not a lot has changed in terms of the Fortuner’s looks over the years and while it stubbornly retains that pleasingly non-offensive exterior of most modern SUVs, it does manage to not be totally bland.

The GXL is a body-on-frame 4WD based the HiLux, so it’s no sports car in appearance whether you gaze at it from the front, side, rear or from a bird’s eye view, but it doesn’t look like a block of rotten wood, so unless you’re looks-obsessed, then you should be okay driving this around.

The Fortuner interior is looking dated and the standard dark grey fabric cloth seats, though well-suited to coping with day-to-day messes and spills, don’t do the cabin any favours either, and – you know what? – I don’t mind any of it. Note our test vehicle on this occasion had black leather-accented seats as part of its GXL Option Pack, but I've spent time in cloth-seat Fortuners.

The interior has a pleasant, familiar and practical feel about it and this is an easy space in which to swiftly become comfortable. 

Controls are easy to locate and operate and charging options are numerous – a mix of USB-A, USB-C and 12V up front, and USB-A for the second row.

Storage places include recesses for your everyday carry gear, a suitably deep 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 cupholders either side of the third row in the MU-X for passengers riding back there.

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

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

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 folded.

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 Fortuner’s cabin has a comfortably familiar feel to it and, thankfully, this interior is all about function not fashion.

It’s a practical space, with standard cloth seats (as mentioned our test vehicle has the Option Pack leather-accented seats, but I’ve spent enough drive time in Fortuners with cloth seats to know how those cope with the mess and dirt of everyday life), carpet floors with rubber mats, and durable plastic surfaces everywhere.

Up front, there’s an 8.0-inch multimedia screen (too small, not clear and bright enough) and that system has USB-connected Apple CarPlay and Android Auto (no wireless anything), and a 4.2-inch colour driver’s display, which is too small, too basic and part of an outdated mix of analogue and not-new-enough digital instrumentation.

There are the usual storage spaces – including a glovebox, a centre console, a tray for your smartphone, pop-out cup-holders on the outboard edges of the dash – and a USB port and a 12V socket for charging purposes.

The Fortuner’s three rows are in a 2-3-2 seat configuration. The 60/40 split-fold second-row seat has a one-touch, tumble feature. The 50/50 third-row seats are able to be stowed away, sort of. When folded to each side they protrude into the load space, reducing the size of what would otherwise be a more useable cargo area.

It’s reasonably comfortable in the second row; I sat behind my driving position and I had adequate head and knee room.

The second row has cup holders in the fold-down armrest, ceiling-mounted controls for the aircon, and two ISOFIX and three top-tether anchor points.

All three rows get aircon – with ceiling-mounted vents – and there are a few storage spaces in the third row, but no cup-holders. 

In terms of comfort, it’s ordinary back here; the seats are flat and unsupportive – and, for anyone other than children, the space is tight. 

Boot space is listed as 200 litres with the third-row seats in use, and in that area there are cargo hooks and a 12V socket.

Stow away the third-row and cargo space increases to 716 litres. But the seats still jut into the cargo area, greatly reducing your actual useable load space, and they also obscure a lot of driver vision to the rear.

With the second and third rows out of the way you have a listed 1080L of cargo area.

Our test vehicle is the GXL, the mid-spec variant in a line-up topped and tailed by the base-spec GX and the top-shelf Crusade.

The GXL has a starting price of $58,895 plus on-road costs.

Standard features onboard this seven-seat 4WD wagon include a 8.0-inch multimedia touchscreen (with Apple CarPlay and Android Auto), a six-speaker sound system, digital radio, manually adjustable seats and 17-inch alloy wheels.

Exterior paint choices include Glacier White (no extra cost) or premium paints Frosted White, Graphite, Stunning Silver, Eclipse Black, Feverish Red, Phantom Brown, and Saturn Blue, which all cost $675 extra.

Our test vehicle has the Option Pack, which includes black leather-accented seats and eight-way power-adjustable front seats.

The MU-X has a 3.0-litre four-cylinder turbo-diesel engine, producing 140kW and 450Nm and it’s matched to a six-speed auto.

These form part of a proven powertrain and while the MU-X may not be the most dynamic vehicle to drive – it’s acceleration is sluggish rather than punchy – it has a real tractability that nullifies any other niggles.

It has part-time 4WD, with high- and low-range as well as various drive modes, rough terrain mode, and a rear diff lock.

Every Fortuner in the line-up has a 2.8-litre four-cylinder turbo-diesel engine – producing 150kW and 500Nm – and that’s matched to a six-speed automatic transmission.

In terms of performance, the Fortuner is not going to set any hearts a-flutter: it’s sluggish off the mark, it takes a heavy right boot to make it feel like anything other than lacklustre on the move, and the six-speed auto downshifts quite harshly at times, especially when going up or down long, gradual inclines on the highway.

However, the 4WD set-up is effective, with adequate low-range gearing, a quietly efficient (but a tad clunky) off-road traction control system, and a rear diff lock.

Official fuel consumption for this MU-X is 8.3L/100km and that's on a combined cycle. 

On this test I recorded 10.2L/100km. I did a lot of high and low-range four-wheel driving, so that fuel consumption is not too shabby.

The MU-X has an 80-litre fuel tank, so going by my on-test fuel consumption figures you could reasonably expect a driving range of about 784km from a full tank. 

The Fortuner has official fuel consumption of 7.6L/100km.

On this test I recorded 9.6L/100km.

Going by my on-test fuel figure, you could reasonably expect a driving range of about 833km from this Fortuner’s full 80-litre tank.

In previous tests, the MU-X has been fine on road and more than adequate on gravel, dirt tracks, and during low-range 4WDing. But it’s been a jarring, skippy ride on irregular surfaces rather than as composed as it could – and should – have been. The culprit? Firm suspension, over-inflated tyres, too-tight trousers, who knows?

The good news is it seems like Isuzu has ironed out any issues in the suspension, minor or otherwise, because the MU-X is now is a lot better in terms of ride and handling than ever before. 

Off-road, the MU-X has always been a proven combination of its 3.0-litre, four-cylinder turbo-diesel engine, clever six-speed automatic transmission, and an off-road traction control system that's been increasingly well recalibrated through a number of generations. 

The engine is tractable and gruff, it has plenty of grunt and, as long as you're not driving like a complete hoon, you can usually get through most obstacles without a lot of fuss.

It's this mix of mechanicals and driver-assist tech that make the MU-X such an effective 4WD package. And there are a number of reasons for that. 

For one, that engine delivers plenty of torque down low and in the mid-range torque and that's crucial for four-wheel driving. 

And another thing, Rough Terrain Mode – like a beefed-up and fine-tuned off-road traction control – proves very effective because it punches torque to the wheel with the most traction – while wheel spin on tyres that aren't touching dirt is minimised – and that way it keeps the vehicle moving through obstacles with safe and controlled momentum. 

As I’ve noted before though, Rough Terrain Mode is not a magic all-conquering solution, but it is another handy addition to the MU-X’s off-road toolbox.

And the MU-X also has a rear diff lock to back you up – and that's another valuable component. 

The MU-X has approach, departure and ramp-over angles of 29.2, 26.4 and 23.1 respectively.

A listed 235mm of ground clearance is about standard for this kind of wagon but, as I’ve said before, it seems vulnerable in the underbody, side steps and its plastic mud guards. So the underbody may touch dirt, depending on how challenging the terrain is. 

Wading depth is listed as 800mm.

But, as always, with focused driving, you’ll have lots of fun and you'll minimise any superficial damage or scuff marks to the MU-X.

The MU-X has plenty of potential as a touring platform, but, if you’re planning to do any off-roading beyond well-maintained tracks, then get rid of its road-biased tyres and replace them with all-terrain tyres.

The showroom-standard tyres on this MU-X – 265/50R20 Bridgestone Dueler HTs – are okay, but not really up to scratch if tough 4WDing is what you’re keen to do. I’d prefer an 18-inch wheel and tyre package with decent all-terrains.

The MU-X has a full-sized underslung spare and in terms of packability, the MU-X X-Terrain has a listed payload of 605kg, GVM is 2800kg and GCM is 5900kg.

If you are considering using your MUX as a tow vehicle, it's handy to know that it can legally tow 750kg (unbraked) and 3500kg (braked), which is the standard for large four-wheel-drive wagons. 

Be aware though that, as with any other vehicles, once you're towing anywhere near the maximum weight, your payload is greatly reduced.

On-road, the Fortuner offers up a pretty standard driving experience for a ute-based wagon. It’s on the HiLux ladder-frame chassis, and it has a firm ride, bordering on harsh. Having said that, you do get used to it soon enough and the Fortuner's coil-spring suspension set-up takes most of the sting out of surface irregularities, except for the more severe dips and bumps.

The Fortuner’s driving position offers plenty of visibility – although the A-pillars are bulky and the third-row seats block vision to the rear when they’re folded up to the sides of the cabin.

This 4WD wagon is generally quiet, although there’s noticeable wind-rush noise around the wing mirrors and engine noise builds to a diesel shriek when you use a heavy right boot as is regularly required.

Steering – reach- and rake-adjustable – is adequately light and sharp, and the Fortuner, with its 11.6m turning circle, is reasonably nimble in suburban areas.

Acceleration, from a standing-start or for overtaking, is laggy but available power and torque come in handy during general driving, making the Fortuner more agreeable all-round than previous versions.

The six-speed auto is generally right for the job, but it downshifts harshly, especially when going up or down long, gradually sloping highway stretches. That happens enough for it to be on the wrong side of annoying.

Some aspects of the Fortuner’s driver-assist tech is annoying: active cruise control is too abrupt and pre-emptive, consistently miscalculating the space between the Fortuner and the vehicle in front as accurately as most of its rivals. This clunky application of tech to real-world scenarios works against the Fortuner. 

While driving a lightly corrugated and rutted dirt track o the way to our set-piece off-road tests, the Fortuner’s ladder-frame chassis yielded a stiff, firm ride, bashing and bouncing over any and all surface imperfections. Airing down the Yokohama Geolandar ATs (265/65R17) from 38 psi (pounds per square inch) to 26 psi takes some sting out of the ride.

The Fortuner is a very capable 4WD with standard off-road measurements, including ground clearance (216mm), approach angle (29 degrees), departure angle (25 degrees) and rampover angle (23.5 degrees). It has a listed wading depth of 700mm.

The Fortuner’s switchable part-time 4WD system has two-wheel drive (H2), and high- (H4) and low-range (L4) four-wheel drive. There’s ample low-end torque on offer – on tap across a broad rev range – for controlled low-speed 4WDing and the unfussed turbo-diesel engine keeps the Fortuner ticking along, without any hassle. 

Engine braking is good, keeping the Fortuner to a sustained and composed momentum on downhill runs.

The off-road traction control system is an effective set-up, limiting wheel-spin and sending much-needed torque to the tyres with some useable traction, with the aim to keep the vehicle moving along at a safe, controlled pace.

Besides that, the driver always has the option of engaging the rear diff lock for more traction action.

Wheel travel is decent for a wagon like this and if you can get the full suspension flex, and drop any mid-air tyres to the dirt for more traction, chances are you’ll be able to get moving along safely soon enough.

So, the mechanicals are fine – its 4WD set-up is very effective – but the Fortuner doesn’t have a whole lot of ground clearance (a claimed 216mm, standard for a contemporary 4WD wagon) and the side steps are prone to hitting on the edges of steep and deep ruts, but those factors are easily overcome through considered driving and tyres that are better suited to off-roading. 

The standard Yokohama Geolandar AT tyres are somewhat of a flaw in the Fortuner’s off-roading set-up. Sure, they’re technically all-terrains, but I reckon a better bet for you – if you’re planning to drive anything beyond formed trails – is to invest in a set of more aggressive all-terrains with greater sidewall bite. 

If you’re planning to use your Fortuner to tow anything, keep in mind that it has a 750kg unbraked towing capacity and 3100kg braked towing capacity. Remember: to be on the safe side, avoid going loading up to anywhere near those capacity figures.

Payload is 615kg (easily reached when you factor in people, pets, camping gear and more), gross vehicle is (GVM) is 2800kg, and gross combined mass (GCM) is 5900kg.

The Toyota Fortuner GXL has the maximum five-star ANCAP safety rating from testing in 2019. Note the ANCAP safety rating for the Fortuner is based on crash tests of the Toyota Hilux.

Standard safety gear includes seven airbags and driver-assist tech, including AEB with pedestrian (night and day) and cyclist detection (day only), active cruise control, lane departure alert, road sign assist and more.

The MU-X has a six-year/150,000km warranty and seven years of roadside assistance. That warranty is okay in terms of years, but unlimited kilometres 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 24MY and later vehicle models (up to five years/75,000km, whichever occurs first) – at a cost of $469 for each service.

A five-year/unlimited kilometre warranty covers the Fortuner, which is par for the course these days.

If you stick to the relatively short servicing schedule – six months or 10,000km with at authorised dealerships – Toyota says it will cover the engine and driveline for up to seven years. All warranty elements are subject to terms and conditions, so make sure you’re fully aware of those.

Capped-price servicing applies and, for our test vehicle, it was $290 per appointment for the first five, then $377.38, $813.93, $572.55, $478.93 and $377.38.
