Isuzu MU-X vs Mahindra Scorpio-N

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...

It might seem like I’ve been harsh on the Scorpio but I actually reckon this vehicle is in fact a step in the right direction for Mahindra.

It’s nice enough to drive on-road – refined and comfortable – and it’s also a capable 4WD, with a few issues though…

It’s a good value-for-money prospect but it’s lacking a lot of driver-assist tech that should be onboard every modern vehicle, especially one that will serve as a family mover.

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 Scorpion reminds me a bit of the early-generation Hyundai Terrcan – long bonnet, generic cabin, and it appears to sit quite low.

The Mahindra SUV has 18-inch alloy wheels, side steps, roof rails and sunroof.

It all looks fine and, anyway, the more interesting stuff on the Scorpion is under the skin – the fact that it is a body-on-frame 4WD.

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 cabin is tidy and functional. The 8.0-inch touchscreen multimedia system is easy enough to operate without strife and the screen is clear, although it’d be great if it was bigger.

The tan synthetic leather interior trim looks good and superficially the whole interior looks nice, but if you inspect a little more closely the Scorpio’s cabin is missing the storage spaces, USB charge points and build quality of rival SUVs.

There’s one cupholder (between driver and front passenger), the door pockets are narrow and there are few other storage spaces.

With the third-row seats in use, there’s a very small rear cargo area, and those seats don’t fold flat so when they’re not in use they seriously impact the storage space.

As a result, the Scorpio is one of the few modern 4WDs that I’d consider taking out the third row every time long-distance loaded-up travel was on the cards – just so it’s a more practical touring vehicle.

Some features, such as the directional air vents, feel flimsy. Otherwise, the Scorpio’s cabin is suitably practical, rather than overly impressive.

The Scorpio is available in two grades: the Z8 with a drive-away price of $41,990 (at time of writing) and the Z8L at $45,990 drive-away (at time of writing), which we tested.

Standard features in the Z8L include an 8.0-inch touchscreen multimedia system (with wireless Apple CarPlay & Android Auto), wireless phone charger, a 12-speaker Sony stereo, dual-zone climate control, front camera (intended for off-road use), front and rear parking sensors, and a six-way power-adjustable driver’s seat.

It has a leather wrapped steering wheel and gearshifter, tan- and 'rich coffee'-coloured synthetic leather interior trim, a cooled glove box, sunroof, and six-seat layout (with two captain's chairs in the second row).

It has 18-inch alloy wheels, automatic wipers and projector LED headlights, push-button start, keyless entry and a tyre pressure monitoring system.

Our test vehicle also had floor mats ($200) and side steps (approximately $1250 fitted) as the only accessories.

Exterior paint choices include 'Deep Forest', 'Everest White', 'Napoli Black' (on our test vehicle), Dazzling Silver' and 'Red Rage'.

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.

The Scorpio has 2.2-litre four-cylinder turbo-diesel engine, which produces 129kW at 3500rpm and 400Nm at 1750-2750rpm.

It has a six-speed automatic transmission, an auto-locking rear diff, and a part-time 4WD system with a dual-range transfer case incorporating low range.

Note: the Scorpio must be in neutral and stationary for the driver to shift into 4WD low-range, but the driver is able to shift between 2WD and 4WD High on the move, up to 80km/h.

Its '4Explor' system’s drive modes include 'Normal' (2WD for sealed surfaces), 'Grass/Snow' (4WD), 'Mud & Ruts' (4WD), and 'Sand' (4WD).

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. 

Official fuel use is listed as 7.2L/100km on a combined cycle.

Fuel consumption on this test was 9.6L/100km, which is impressive, especially in light of the fact that we spent the lion’s share of two days during the test period in 4WD low-range.

It has a 57-litre fuel tank, so, going by those fuel figures, you could reasonably expect a driving range of about 593km out of a full tank. 

Note: That 593km is a best-case scenario figure and has not had a 30-50km safe-distance buffer subtracted from it, and it also does not take into account the fact that, when being used for touring, the vehicle will be loaded with people, pets, camping gear and more.

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.

The Scorpio is a 4WD with a body-on-frame chassis. For those of you who don’t know (no shame in that) a body-on-frame chassis denotes a chassis onto which the vehicle’s separate body is attached, and the engine, wheels, and suspension are fitted.

The set-up is well suited to towing and/or carrying heavy loads, and 4WDing.

It’s 4662mm long (with a 2750mm wheelbase), 1917mm wide and 1857mm high. It has a listed kerb weight of 2100kg and a 12.6m turning circle.

Right, that’s enough (boring?) measurements for now.

This Mahindra 4WD is surprisingly refined on-road: quiet inside, comfortable and with a no-stress engine and a low-key workmanlike Aisin-sourced auto delivering a relaxed, almost lethargic combination on the road.

Steering has a nice weight to it, ride quality is okay, erring on the side of spongy rather than too firm, and some body roll creeps in on more energetic bends.

Overall, however, the Scorpio does satisfactorily well on sealed surfaces. But how does it perform off-road?

The Scorpio handled the undulating dirt track leading to our off-road test site with ease, riding nicely over the light to medium corrugations, and was only ever minimally unsettled by the bumpy terrain.

This Mahindra is able to be shifted between 2WD and high-range 4WD (4H on the dial) so you can keep moving even when the road/track surface changes all of sudden.

The Scorpio has plenty of old-school foundational 4WD mechanicals onboard – low-range and a rear diff-lock (albeit an automatic one) – and it also benefits from off-roading-oriented tech such as its 4Explor system with selectable terrain modes, each of which adjusts engine output, transmission settings and traction control to best suit the terrain, conditions and driving style. 

It also has hill descent control and hill hold control.

Even its forward-facing camera comes in handy. I still think of these as more a novelty – I prefer to get out and check the track ahead or get a spotter to do the work for me – but I can see the inherent value of this tech in helping the driver to maintain vision, especially if forward visibility is compromised, say for instance up and over the crest of a steep rocky hill, or edging towards a steep drop into a creek bed.

While the Scorpio’s 400Nm may seem a bit lowly, that torque is on tap across a good spread of revs, and this 4WD does well with what it has. The engine keeps everything moving along nicely.

In terms of off-road-relevant measures, the Scorpio has 227mm of ground clearance, a guesstimated wading depth of 500mm or so (it’s not listed), and approach, departure and ramp-over angles of 27.2 (good), 21.3 (not so good), and 23.5 (okay) degrees, respectively.

The Scorpio is quite an effective off-road wagon and it tackled every obstacle it faced without fail, but it has to be driven with extreme care and laser-focused concentration.

No harm in that, I hear you cry. In response, I say, sure, but it’s bloody exhausting work having to nurse a vehicle through even innocuous terrain in order to avoid nudges, bumps and scrapes to its underbody and side steps.

Not to mention how tiring it is having to anticipate if/when off-road traction control and/or the auto diff-lock will engage – or not – at crucial moments.

Not a major concern on flat ground, but think about the auto rear diff-lock cutting out on you while driving up a rocky 32-degree hill. Yep, I’m old.

Now for some more of the Scorpio’s less-than-ideal characteristics.

1. I hinted at this in the previous paragraph: off-road traction control doesn’t seem as well calibrated as it should be. It’s a bit patchy in its application, and certainly not as seamless as the tech in something like the GWM Tank 300 (yes, I know – the Tank costs about $15,000 more.)

2. The automatic rear diff lock is on the wrong side of clunky, abruptly engaging as it senses wheel-spin then disengaging just as abruptly when it deems the problem over ... even if it isn’t quite over yet.

3. The Scorpio feels low: a lot of underbody components are vulnerable to rocks, tree stumps, track debris, and the AdBlue tank sits low behind the rear left-hand wheel.

4. The side-steps seem very flimsy. The right-hand side-step took a soft knock going over an exposed tree root early on one test day, which I thought nothing of. But when I looked at it soon afterwards, the fasteners had popped out at the front and middle of the sidestep.

I didn't think the bump had been anywhere near enough to result in that.

5. The Scorpio’s standard tyres – MRF Wanderer SUV tyres (255/60R18 “All-Season”) – are not great for hard 4WDing.

They don’t offer anywhere near the degree of grip you need in difficult 4WDing and they quickly became gummed up with mud. The Scorpio does have an underslung full-size steel wheel spare.

The Mahindra Scorpio Z8L has a listed payload of 510kg, and can legally tow 750kg (unbraked), and 2500kg (braked). Gross vehicle mass (GVM) is a listed 2610kg; gross combined mass (GCM) is 5155kg.

I experienced a bit of an issue on a drive home after a few hours of tough 4WDing: 4H kept trying to engage during a 100km stretch of highway.

A dot kept flashing above 4H near the shifter, and terrain modes (other than Normal) kept flashing on the centre console and driver info display and I was being prompted to drop below 80km/h to shift into 4H.

Of course, I’d earlier switched from 4H to 2WD at the end of our filming day (at the 4WD location) and made sure I'd engaged Normal mode before I left the dirt and drove onto a sealed surface.

When the 4H-related issues kept happening on the highway I was able to fix the problem by stopping, switching the Scorpio off and back on again – but I had to do this every 5.0km or so four times before it finally sorted itself out.

To Mahindra’s credit, technical staff members are looking into the issue.

The Mahindra Scorpio Z8L does not have an ANCAP rating because it has not been tested.

As standard, it has six airbags (front, front side and curtain), electronic stability control, front and rear parking sensors, a tyre pressure monitoring system, as well as trailer sway and roll over mitigation, hill hold control and hill descent control.

It lacks a lot of driver-assist safety tech that’s onboard a lot of other vehicles at this price-point, and even cheaper.

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.

The Mahindra Scorpio Z8L has a seven-year/150,000km warranty.

Service intervals are scheduled for every 12 months or 15,000km.
