Isuzu MU-X vs Mitsubishi Eclipse Cross

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 Mitsubishi Eclipse Cross Plug-in Hybrid EV is an interesting inclusion for the brand, especially as it is typically considered a ‘value player’ in the market.

But with negligible real-world fuel consumption benefits if you drive beyond the limited EV range and a high price premium over the non-PHEV models, it’s important you see if the sums add up for your particular needs.

Primarily going to use the car for running around town? Cool. Think the 50-ish-kay EV range will work for you and make you happy? Amazing. Sold on the look of the car? Hat tipped.

But let me say this - if you are considering the Eclipse Cross PHEV, there are some alternatives you should also have on your list, including the MG HS PHEV, the Hyundai Ioniq PHEV, Kia Niro PHEV, and - the one I’d buy - a Toyota RAV4 Hybrid. For me, plug-in hybrid tech is a bit of a halfway house, in most instances offering too high a price premium for the range you’re getting to drive electric. Heck, a Kona Electric isn’t much more than the top-spec Exceed PHEV, and I’d have that if I wanted a real day-to-day EV experience.

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.

You’re going to be able to tell the PHEV model from its more conventional counterparts by those oversized ‘Plug-in Hybrid EV’ badges on the front doors, and if you want to tell those behind you what you’re driving, there’s also a ‘PHEV’ badge there, too. Wait, wasn’t the plan to do away with the term ‘PHEV’, Mitsubishi? 

But aside from that, the outside features just the different 18-inch alloy wheels (which are the same on all PHEV models, no matter the cost - I think that’s a bit lame, because if I’m spending $7500 on the Exceed I’d like a different wheel design!). Oh, and the Aspire and Exceed get that different lower front splitter, too.

Plus the PHEV has two fuel filler doors - one on each side of the car over the rear wheels. The driver’s side one is the EV charging ports (x2 - detailed below), and the passenger’s side one is for the petrol. Note: while the EV port is push-openable, the petrol cap still requires you to lift a lever in the driver’s footwell. 

It may be categorised a small SUV but at 4545mm long, riding on a 2670mm wheelbase, 1805mm wide and 1685mm tall, it’s big for its boots. The popular Mazda CX-5 is only 5mm longer, and it plays in the midsize SUV segment!

Inside there are some design differences, with a specific gear joystick-style selector, and a different instrument panel.

It is impressive how the brand has managed to shoehorn a petrol engine, two electric motors, a battery pack and more into the car, but there are some practicality implications. Read about them in the next section.

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.

Up front, the cabin is a pretty smart place, with nice enough materials and finishes, and a few good storage options. There’s a cubby in front of the shifter, but oddly enough it doesn’t have a wireless charger (there are 2x USB 2.0 ports above) and isn’t quite big enough for a smartphone (even the smaller ones don’t fit there all that easily), and there are cup holders between the seats, a decent covered centre console bin, and door pockets large enough for bottles.

The PHEV models get a different instrument cluster dial for EV driving readout info, but all have the old-school 4.2-inch TFT colour display that lacks the size and usability of some rivals with larger info screens - the MG HS PHEV, for instance, has a 12.3-inch digital display, which shows you a lot more info than this tiny little screen does. Heck, there’s not even a digital speedometer in there - and you only get one if you buy the Exceed model, which has a head-up display (HUD).

That’s part of the problem with the way this car’s interface operates. If you want the most detailed information you need to use the touchscreen media system, but that negates the usability of the media functions. On multiple occasions I found myself switching between Apple CarPlay phone calls and searching for that particular driving info screen I found most useful (there are about 15 screens to choose from, and plenty of them are hard to decipher).

It’s a huge disappointment for a customer who might want to see all that detailed information but also listen to a podcast, answer a call, follow their phone’s mapping or just have anything other than the hybrid info come up on the infotainment screen. The screen itself - an 8.0-inch unit, with sat nav integrated into the top spec only - is fine, but small compared to today’s rivals.

In the back seat, there’s a compromise for cabin space. The leg room is good, but the seat has been bumped up to accommodate some of the electrical hardware and the petrol tank, meaning someone my size (182cm/6’0”) will find they’ve got enough room for their legs but not their head, and those even larger will really need to take care getting in and out. While pre-facelift examples of this car had a clever sliding second row seat, that’s gone. It was never a feature in any PHEV version, and undoubtedly the layout of the battery pack has something to do with that. 

The double pane sunroof no doubt eats into the space in the rear to a degree as well, and in the Exceed it likely feels a bit more cramped because of the black headliner. 

While three adults could potentially fit across the back row for very short trips, there are dual ISOFIX and three top-tether points for child seats. The Exceed is the one you want if you’re aiming to treat your rear-seat passengers right: it has heated rear outboard seats, rear directional air vents and two USB ports for charging - the ES and Aspire miss out on all that stuff.  

Boot space is 359L (VDA) for PHEV models, which is a step down from the 405 litres (VDA) for the non-hybrid models. There is extra hardware under the floor, and you don’t get a spare wheel in the PHEV models either - instead there’s a tyre repair kit. For context, we only just managed to fit all three CarsGuide hard suitcases (124L, 95L and 36L) in the boot of the PHEV version, while it was far less of an issue in the non-PHEV.

Oddly, no model comes with a power tailgate. 

The 2022 Eclipse Cross PHEV line-up is expensive compared to the petrol-turbo models.

The ES AWD has a list price (all prices MSRP, before on-road costs) of $46,490, while the mid-spec Aspire costs $49,990 and the top-end Exceed lists at $53,990. 

I know they’re not like-for-like in every instance - the ES and Aspire petrol-turbo models are 2WD, not AWD, for example, and there are some specification differences, too - but the price jump from each respective non-PHEV version is $15,500 (ES), $14,250 (Aspire) and $12,500 (Exceed).

Yikes.

You’d really, really have to want the EV driving experience to justify that additional expenditure, right?

Here’s a rundown of the specifications across the three PHEV grades.

Standard for the $46,490 ES grade are 18-inch alloy wheels, LED daytime running lights, halogen headlights, keyless entry and push-button start, cloth interior trim, manual front seat adjustment, an 8.0-inch touchscreen media system with Apple CarPlay and Android auto, a reversing camera, a four speaker stereo, digital radio and a rear cargo blind.

Step up to the $49,990 Aspire and you score LED headlights and fog lights, a lower body kit, heated front seats, faux-leather and microsuede trim, auto wipers, adaptive cruise control, an eight-speaker stereo, surround view camera, front and rear parking sensors, and an array of safety equipment that we’ll cover off in the safety section.

Choosing the range-topping $53,990 Exceed model nets you leather seat trim, a heated steering wheel, a head-up display - making it the only grade with a digital speedo! - as well as sat nav, a dual pane sunroof, and a black headliner in the cabin.

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 plug-in hybrid version runs a non-turbocharged 2.4-litre Atkinson cycle petrol engine producing just 94kW and 199Nm.

Meagre outputs, but the petrol unit is backed by two electric motors - the front motor has outputs of 60kW/137Nm, while the rear motor produces 70kW/195Nm. It’s all controlled by a single-speed transmission.

There is no ‘combined power output’ figure, but there is a 13.8kWh lithium-ion battery pack as part of the equation as well.

The engine can power the battery pack in series hybrid driving mode, so if you want to top up the batteries before you get to a city, you can. And there is regenerative braking, of course. More on recharging in the next section.

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 Eclipse Cross PHEV has an official combined cycle fuel consumption figure of 1.9L/100km. That’s astounding, really, but you need to realise that the test calculation is only for the first 100 kays - there’s a really good chance your real-world consumption will be a lot higher, as you can only deplete the battery charge once before calling on the engine (and your petrol tank) to juice it back up.

Electric driving range is stated at 55km based on NEDC cycle testing, while the WLTP rating is a more realistic 45km. In our testing we fell between the two during our “fully charged” 100km run, in which the electric charge initially ran for 50km. But, over the 100km run, the dashboard info screen said the car used “82 per cent” electric driving, while somehow also showing 3.9L/100km for petrol consumption.

I did the numbers at the fuel filler, and the actual return was 4.5L/100km. That’s okay, but not nearly as spectacular as you might hope, and I’ve seen very close in a RAV4 hybrid - which in most instances is cheaper than the Eclipse Cross despite being bigger and, frankly, a lot better.

I also ran the car for a further 100 kays without plugging in, just to see what the ‘worst case scenario’ might be - and it wasn’t too bad, with the fuel consumption jumping to a real-world return of 5.5L/100km. But again, that’s worse than you’ll likely get with a RAV4…

When it comes to charging/recharging, there is available AC charging using a Type 2 plug that can fully recharge the battery in as little as 3.5 hours, according to the brand. DC fast charging with a CHAdeMO plug should fill from zero to 80 per cent in 25 minutes. Maximum charge input is 3.6kW.

Like me, you’ll want to do the maths to see what is going to be the most economical way to run your car - aside from just plugging it in at the office and hoping nobody notices.

A standard 10-amp household plug - which should take about seven hours to replenish the batteries - could cost as little as $1.88 to get back your circa-50km EV range - that’s based on overnight charging, off-peak, on an average 13.6c/kWh electricity price. Of course, if you’re considering a PHEV, you might have a solar array and the electricity could well be free. Good for you.

But remember, there’s more to it than just the electricity costs - you need to also consider the additional purchase budget required just to get into the PHEV model over a regular Eclipse Cross. 

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.

If you’re after that electric car thrill of near-silent, almost mind-blowing acceleration, the Eclipse Cross mightn’t be the right car for you

But if swift progress and the buzz you get from taking off from the traffic lights without any hesitation at all is more your thing, it could be great for you. And if you’re not quite ready to go “full EV”, then it’s probably something you’re considering.

The EV driving mode is the best driving mode in this car. You can run it just on the petrol engine to ensure you save your battery range, and you might choose to do that when you’re driving on the freeway and know you’re approaching an urban area where the EV goodness will be better used. Or you could have it so it's using battery and petrol power, and that’s where you’ll get maximum combined performance.

But running the car in the default, EV-prioritised mode means you will make the best of this powertrain's strengths, because - for the fifty odd kays you’ll get out of the battery - it’s pretty good.

It’s also impressive the way this powertrain dips between petrol engine, battery pack or both at higher speeds. When the battery range had depleted on my test drive, the engine kicked in almost imperceptibly, working to power the car and also generate more electricity for the battery pack. It then dipped out of petrol, back to battery, and so on and so forth, multiple times during my drive. 

The best thing about the way it did so was that it was smooth. There is barely any vibration from the petrol engine, the transmission doesn’t have any gears to fumble with, and overall the refinement is really good.

There are drive modes - Eco, Normal, Snow, Gravel and Tarmac - and in my test I kept to Normal. I did fiddle with the regenerative braking reactiveness, though, using the paddleshifters to dial up or down the aggressiveness of the energy recoup system. It doesn’t feel as aggressive as some pure electric cars, but thankfully it has a decent pedal feel and progression when you apply the brakes yourself. 

The steering is light and lacks feel, and doesn’t offer that much engagement or involvement. That might matter to you if you’re like me. I wish it was more fun. But at least it’s easy to park.

While the suspension is fine and comfortable on the highway, it can feel wooden and the ride is quite lumpy at low speeds. It never really feels all that well resolved for urban driving, which is a bit of a downer considering that’s likely where a car like this will spend most of its time

The tune of the suspension - being a bit firm at lower pace - surprisingly doesn’t have any payoff when it comes to cornering, as it lacks a bit of body control, shifting its weight side to side. 

All in all it is a decent plug-in hybrid offering – and will be perfectly suitable to someone who wants some EV driving as a part of their lifestyle. It’s just a matter of doing the maths as to whether it will work for you.

All Mitsubishi Eclipse Cross models have been awarded a five-star ANCAP crash test safety rating based on 2017 testing for the pre-facelift model. 

The range has increasing levels of safety technology the more you spend, but all variants have forward autonomous emergency braking (AEB) with forward collision warning (operates between 5km/h and 80km/h) and the AEB includes pedestrian detection (between 15km/h and 140km/h). 

Standard on all grades is a reversing camera, rear parking sensors, seven airbags (dual front, driver’s knee, front side, side curtain for both rows), active Yaw control, stability control, and anti-lock brakes (ABS) with brake force distribution. Lane departure warning is standard too.

Spend up on the Aspire for adaptive cruise control, blind-spot monitoring, rear cross-traffic alert, and front parking sensors. From Aspire up to Exceed, there’s the addition of the brand’s Ultrasonic Misacceleration Mitigation System, which can dull throttle response to prevent potential low speed collisions.

No speed sign recognition is available, and therefore no smart cruise control either. Plus there is no lane centring system fitted either, and nor is there a driver attention monitoring system, so it’s falling behind on the tech front.

The Mitsubishi Eclipse Cross is built in Japan.

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.

There’s a huge 10 year/200,000 kilometre warranty on offer - but it’s valid if you maintain your car with Mitsubishi’s dedicated dealer service network over the 10 years/200,000km timeline, or else you get a five-year/100,000km plan.

But while the rest of the car will be covered by that decade-long warranty if you service it with Mitsubishi, the battery is only covered for eight years/160,000km, no matter where you have the car serviced.

Maintenance is due every 12 months/15,000km. But just a note - the more complex powertrain means higher service costs than the regular turbo-petrol versions. The annual fees are: $299, $399, $299, $399, $299, $799, $299, $799, $399, $799; so an average cost of $339 for the first five years, or $558.90 per visit over 10 years/150,000kn. 

Included for customers who service their car with the brand is four years of roadside assist.
