Mitsubishi Outlander vs Isuzu MU-X

What's the difference?

The Outlander PHEV in GSR spec is a nifty daily driver, quietly appealing and more than capable of heading off-road as long as you drive it well within its AWD limits.

If you reside in the city or suburbs and your daily driving is not too punishing in terms of distance, then this PHEV makes a lot of sense. A hybrid vehicle is a happy-compromise move towards an EV future – and the Outlander PHEV is a big step in the right direction.

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...

In terms of exterior dimensions, this PHEV is 4710mm long (with a 2706mm wheelbase), 1862mm wide and 1745mm high.

The Outlander is an inoffensive-looking AWD wagon with an appearance every bit in line with its GSR spec and price-tag without going over the top.

On the outside, this top-shelf GSR incorporates Mitsubishi’s 'Dynamic Shield' design facade, which was divisive in its early years but has since attracted its fair share of fans.

On the inside, this Outlander has black leather-appointed upholstery with silver stitching, the same treatment applied to the soft-touch armrests, centre console top, sections of the dash and elsewhere.

And the big 20-inch machined alloy wheels top off a classy yet relatively subdued overall look.

In the realm of medium-sized city-going SUVs with weekend road-trip inclinations – think Hyundai Santa Fe, Kia Sorento, Kia Sportage and the Outlander’s hybrid rivals like the Nissan X-Trail e-Power, Toyota RAV4, et al – this Mitsubishi AWD more than holds its own because in terms of design none of them are bound to set hearts a-flutter. But they’re all fine. 

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.

This SUV has a family-friendly and functional interior with a premium feel, even if it does seem somewhat underdone for the price.

But it has all the right elements of a family tourer, in a cosy cabin in which it’s easy enough for driver and passengers to spend a chunk of time on lengthy road trips without complaint. I know, because we did.

The GSR has comfortable leather seats, a (mostly) user-friendly multimedia system, plenty of charge points (USB-A and USB-C up front and two USBs for second-row passengers), lots of soft-touch surfaces and a reasonable amount of storage space peppered throughout.

Nice touches, such as the heated steering wheel and heated front seats, which also have the massage function, top off what is an impressive interior.

There is wired charging for smartphones with Apple CarPlay or Android Auto, as well as a wireless charging pad. There are also 240V/1500W power outlets.

The 9.0-inch multimedia touchscreen is too small for me (perhaps a case of Old Bloke Eyes?), but it’s better when engaged in Apple CarPlay mode. The 12.3-inch high-resolution digital driver display is simple enough to use, and the 10.8-inch head-up display is a handy feature.

The driver has an eight-way power adjustable seat, so they’re able to dial-in their favourite driving position.

As stated, this Outlander’s seats are comfortable with a reasonable amount of room for everyone, though the third row is a tight fit for anyone other than children.

The second row is a 40/20/40 split configuration, while the third row is 50/50.

In terms of packing space, there is 191 litres in the rear cargo area when all seats are being used, 461 litres when the third row is folded flat, and 1387 litres when the second and third rows are stowed away.

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 MU-X X-Terrain 3.0L 4x4 is priced at $74,400 before on-road costs, or $73,990 drive-away for now.

Standard features include a 9.0-inch multimedia touchscreen system with sat-nav, wireless Apple CarPlay and Android Auto, an eight-speaker sound system, eight-way power-adjustable driver’s seat (four-way power-adjustable front passenger seat), remote engine start, smart entry and start, and 20-inch machined-alloy gloss-black wheels on 265/60R20 Bridgestone 684II HT tyres.

As part of the X-Terrain package, it has XT badging in the grille mesh, on fender and tailgate, leather-accented seats with red stitching, gloss-black fender flares and fender garnish.

It also has 265/50R20 highway terrain tyres, red ambient interior lighting with footwell lamp 360-degree, surround-view monitor, and a red-themed 7.0-inch multi-information-display.

Exterior paint jobs on the MU-X X-Terrain include four achromatic finishes: Moonstone White pearl, Mercury Silver metallic, Basalt Black mica and the new X-Terrain exclusive colour, Slate Grey metallic. 

All premium paints (pearl, metallic and mica) cost an extra $695. 

The Outlander PHEV has a 2.4-litre four-cylinder petrol engine producing 98kW at 5000rpm and 195Nm at 4300rpm, an electric motor on the front and rear axles, and a lithium-ion battery pack with a total capacity of 20kWh.

Combined output (engine and electric motors) is 185kW and 450Nm and this PHEV’s electric-only driving range is listed as 84km on a full charge.

It has a single-speed transmission and drive modes include 'Eco', 'Normal', 'Power', 'Tarmac', 'Gravel', 'Snow' and 'Mud'.

It has three power-use settings: 'EV Mode' for low to medium speeds urban running, 'Series Hybrid Mode' which allows the petrol engine to step in for urgent acceleration or climbing hills and 'Parallel Hybrid Mode' for highway overtaking where the vehicle runs on engine power with electric assistance.

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 Mitsubishi Outlander PHEV GSR has a listed fuel consumption of 1.5L/100km on a combined (urban/extra-urban) cycle but, as with all official fuel figures from any carmaker, you can take it with a hefty grain of salt.

That said, if your daily driving distances are within this PHEV’s electric driving range (84km, as listed) and you’re able to drive in EV mode most of the time, then at the very least you will have chopped your fuel bill.

On this test, dash-indicated fuel consumption was 5.8L/100km; actual fuel consumption, as measured from pump to pump, was 7.7L/100km.

The good news is the Outlander PHEV runs happily on the cheaper 91RON 'standard' fuel.

Our dash-indicated power usage was 20.8kWh/100km. This PHEV gobbled through most of its 20kWh battery capacity quite swiftly on the drive from the vehicle pick-up point in Sydney to our test start-point just over 100km away.

It recouped 10km electric driving range via regenerative braking on a series of long downhills when set to ‘Charge’ driving mode (with the combustion engine generating power to the battery), but I had to cycle through regen modes to optimise that power regain.

The dash-indicated combined driving range (battery and engine) was 748km on a full charge and a full 56-litre tank.

Mitsubishi states that if you’re charging off a standard household power point it will take “approximately” 9.5 hours to fully charge your Outlander – or 6.5 hours if you’re using a home or public charging device.

Things speed up considerably if you use a public rapid recharging station. In that case, Mitsubishi says your Outlander Plug-in Hybrid EV will reach 80 percent battery capacity in 38 minutes.

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. 

As mentioned earlier, hybrids are your best buy at this moment in time, if you want to help save the world from climate-change disaster, avoid range anxiety, and save some money on fuel bills – all without having to sacrifice safety, comfort or features.

And – bonus – the Outlander is quite nice to drive. Not to mention a pretty handy light-duty off-roader. But more about that later.

It has a kerb weight of 2145kg with light but sharp steering and a tight (11.2m) turning circle so it’s an easy vehicle to manoeuvre around busy city and suburban streets.

The teaming of a 2.4-litre four-cylinder petrol engine and two electric motors works seamlessly well. There's always plenty of power on tap and, no matter how energetic your driving becomes, this Outlander remains smooth and quiet.

Throttle response is sharp and there’s plenty of punch off the mark as well as zippiness around town when you need it.

The PHEV’s EV-only driving range is a listed 84km but our test vehicle chewed through most of its battery power on a 110km highway trip through hilly territory.

Regenerative braking regained very little of that used power and the Outlander switched to rely on petrol for the remaining 30km or so of that trip.

The driver is able to adjust the degree of regenerative braking via paddle shifters on the back of the steering wheel: use the left to add more and the right to ease up.

The drive mode options tweak engine, electric motor, transmission and other factors to suit the selected set-up.

Other than that, ride is quite firm, handling is civilised and, overall, this Outlander is rather pleasant on sealed surfaces.

And, as I alluded to earlier, it’s surprisingly comfortable and capable off-road – as long as you stick within the parameters of the kind of 'off-road' terrain an AWD SUV is built to cope with: well-maintained gravel roads and dirt tracks with minor corrugations in dry conditions… or, at worst, rain-puddled blacktop.

The Outlander has satisfactory off-road measures for a city-focussed vehicle: of 18.3 degrees (approach angle), 22.2 degrees (departure), 18 degrees (ramp breakover) and 203mm of ground clearance (unladen). 

It feels nimble in the bush because steering is light and precise, visibility is good all-around, and the vehicle settles well on gravel and dirt tracks at speed, only ever skipping around a bit on rougher sections, due to its firm suspension and road tyres.

You can switch drives modes to either Gravel, Snow or Mud to best suit the terrain on which you’re driving but with the Outlander’s lack of ground clearance, road-biased tyres and 20-inch wheels, this SUV is hamstrung by its city-biased physicality.

But, this is still a handy dirt-road tourer, yielding comfortable and controlled ride and handling, only ever becoming rattled when the road or track surface becomes very chopped up and bumpy.

The Outlander’s 'Super-All Wheel Control' (S-AWC) system deserves a fair amount of credit. This traction control system manages torque application so it is instantaneous, and delivers drive with impressive levels of throttle control and an even-handed management of power.

Worth noting the Outlander did, of course, go through battery capacity at a faster pace off-road than it did when we were on sealed surfaces .

Off-roading, by its very nature, is more difficult and demands more of a vehicle than driving on smooth sealed surfaces does. And, for that reason – and the fact the Outlander is quite low – I’d avoid driving this SUV on terrain more challenging than well-maintained gravel roads and dirt tracks with minor corrugations in dry conditions.

I’ve driven an Outlander PHEV on sand before and it taxes the capacity even faster.

As mentioned earlier, this Outlander does not have a spare tyre. The absence of a spare – even a space-saver – is a disappointment, especially if you’re considering using your PHEV as a touring vehicle. A puncture repair kit is provided.

Payload is listed as 605kg, towing capacity is 750kg for an unbraked trailer and 1600kg braked. GVM is 2750kg and GCM is 4350kg.

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 MU-X has the maximum five-star ANCAP safety rating from testing in July 2022.

Standard safety features include eight airbags (dual front, dual seat side, dual full-length curtain, front knee and centre, far-side), and a comprehensive suite of driver-assist tech including forward collision warning, adaptive cruise control, lane departure warning, and a tyre-pressure monitoring system.

New gear onboard includes new hardware for the auto emergency braking ( AEB), like improved vehicle detection, periphery and depth perception, new digital reversing camera with a hydrophobic coating to prevent water and dirt build-up (better visibility off-road), new rear cross traffic brake (detects and reacts to approaching vehicles, cyclists, and pedestrians when reversing), as well as updated lane-keep assist ( smoother steering correction).

The Outlander range is covered by a 10-year/200,000km warranty – as long as servicing is completed on time by an authorised Mitsubishi dealership (otherwise, five years/100,000km) – and 10 years capped price servicing and 12 months roadside assist.

Outlander service intervals are scheduled at 12 months or 15,000km. Service costs can officially range from $349 through to $799 for a 10-year average of $549 per workshop visit.

The battery set-up has an eight-year/160,000km warranty. 

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.
