Isuzu MU-X vs Toyota Corolla 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 Corolla Cross is the SUV that was so obvious it’s a wonder Toyota didn’t do it sooner. Sure, it might not look much like a Corolla but this SUV has the same appeal of being a small, safe good-value for money car but with even more practicality than the hatch and sedan that shares its name. 

The Corolla Cross is also great to drive - better than most of its rivals such as the Mitsubishi ASX, Nissan Qashqai, Honda HR-V or Haval Jolion.

The sweet spot of the range would have to be the GXL Hybrid with 2WD, it's the best value and the most fuel efficient in the line-up.

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 Corolla Cross looks nothing like a Corolla hatchback or sedan from the outside. Although, if I look at the rear of the Corolla Cross and squint I can convince myself it has a similar taillight design to the Corolla sedan.

Personally I’m a bit disappointed in the exterior design of Corolla Cross. The styling already appears dated even though this is a new SUV which was only unveiled to the world for the first time in 2021.

That’s not to say the Corolla Cross is not good looking, it is. I like its tough face and boxy wheel arches - in many ways it’s like a mini RAV4. The problem for me is that like the RAV4 it feels as though the Corolla Cross has already been with us for years and years.

Inside, there are far more similarities to the regular Corolla. The Corolla Cross’ dashboard, steering wheel and centre console are almost identical to those in the sedan and hatch.

This isn’t the plushest cabin you’ll find among the rivals. Even the top-of-the-line Atmos which costs 50 grand doesn’t look very premium or special inside, but like all Toyotas the materials feel high quality and superbly put together.

The real similarities between the Corolla Cross and the Corolla are the mechanical underpinnings with both the SUV and the car versions sharing the same platform.

The Corolla Cross is a small SUV at 4460mm long and that means it nicely in the Toyota family tree above the C-HR which is 4395mm end-to-end and below the RAV4 which is 4615mm bumper-to-bumper.

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 Corolla Cross is a more practical version of the Corolla sedan and hatchback. 

The Corolla Cross’s boot is a lot larger than the hatch’s and while the cargo capacity is smaller than the sedan’s, the wide, tall tailgate opening will mean you’ll be able to fit in bulkier objects.

Boot size depends on which Corolla Cross you choose. The GX and GXL non-hybrid versions have the biggest boots at 436 litres (VDA), while the Atmos non-hybrid is 425 litres.

As for the hybrids, the GX and GXL front-wheel drives also have 425 litre boots, while the GXL and Atmos all-wheel drives have 390-litre and 380-litre luggage capacity respectively.

The reasons for the big difference in capacities between non-hybrid and hybrid Corolla Cross variants are the hybrid batteries which are located under the rear seat and eat into the boot area, while those with all-wheel drive have a second motor at the rear which takes up space.

Room inside is good for a small SUV. Headroom in the second row is excellent, while legroom was just passable for me to sit behind my driving position. I am 191cm tall though, so that’s almost a worst case scenario.

It's fair to say an SUV of this width won't fit three child seats across the back seat, but there are three top tether points across so you can choose which two positions to use. There's also two of the sturdier ISOFIX points in the outboard positions for appropriate baby seats.

Cabin storage could be better, with cupholders in the second-row door armrests, but no actual door pockets and only the Atmos comes with a fold-down centre armrest with two cup holders. There are the usual two cupholders in the front centre console as well, but it's surprising there's no dedicated bottle holders in the doors like most new cars these days.

Up front there are door pockets, a hideyhole under the dash for a phone and a small centre console storage area under the centre armrest.

I do like that the seats are large and accommodating even for me, and the positions of the controls and switches are spot on. 

We can talk about looks later, so let’s see much it costs to buy a Corolla Cross.

First thing to know is there are three grades in the Corolla Cross range. 

The most affordable versions of the Corolla Cross are those with just the petrol engine, not the petrol-electric hybrid options further up the range. The non-hybrid GX lists at $33,000, the GXL is $36,750 and the top-of-the-range Atmos is $43,550.

It’s a good time to point out that if you want a Corolla Cross with a non-hybrid drivetrain then you’ll only be able to get it as a front-wheel drive, not all-wheel drive..

The hybrid variants are available in both front-wheel drive and all-wheel drive. 

So the GX Hybrid front-wheel drive is $35,500. The GXL Hybrid is $39,250 for the front-wheel drive and $42,250 for the all-wheel drive. The Atmos Hybrid is $46,050 for the front-wheel drive and $49,050 for the all-wheel drive.

Got it? You may have noticed the GX Hybrid doesn’t come in all-wheel drive, so yes, you’ll have to step up to the GXL if you’d like it.

Do you need all-wheel drive? It’s not at all vital, but if you’re travelling regularly on gravel roads or snow then all-wheel drive tends to provide much better traction than front-wheel drive.    

Coming standard on the GX are LED headlights and 17-inch alloy wheels, fabric seats, climate control, proximity keys, an 8.0-inch touch screen, Android Auto and wireless Apple CarPlay, a six-speaker stereo and digital radio, a reversing camera plus advanced safety tech covered in detail in the Safety section of this review.

The GXL gets all that and adds roof rails and rear privacy glass, leather upholstered seats and steering wheel, dual-zone climate control, a 10.5-inch display with built-in sat nav.

Now the Atmos, which sounds like a bathroom cleaner but it’s the very fanciest Corolla Cross with its panoramic moon roof and 18-inch alloys, a power tailgate and power driver's seat. Those front seats are heated, and so is the steering wheel. There's a 12.3-inch digital instrument cluster and wireless phone charging.

The Corolla Cross is well-priced compared to its rivals.The Haval Jolion has almost identical pricing across its range but the Corolla Cross goes one better for value by offering a hybrid variant in every grade, not just the top-of the-range as the Haval does. The Honda HR-V is another rival and while it's pricing is close to the Corolla Cross its two-grade line-up doesn't offer much choice. 

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.

How would you like your Corolla Cross to be powered? By petrol-alone or with a combination of petrol and electricity as per the hybrid variants?

The non-hybrid Corolla Cross has a 2.0-litre four-cylinder engine which makes 126kW and 202Nm. Remember, too, it only comes in front-wheel drive.

The hybrid variant combines a 112kW/190Nm 2.0-litre four-cylinder engine with an 83kW206Nm electric motor. And if you choose the AWD then there’s a second motor at the rear axle making 30kW.

Both the non-hybrid Corolla Cross and the hybrid have a CVT automatic transmission. Nope, no manual gearboxes here.  

The braked towing capacity for the range is 750kg. Interestingly, without trailer brakes, most of the range is rated even lower, with the non-hybrid GX and GXL rated at 725kg, the non-hybrid Atmos at 735kg, and the hybrid GX at 745kg. The hybrid GXL and Atmos get the full 750kg, regardless of trailer braking.

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. 

If you want to save fuel the hybrid is absolutely the way to go with the front-wheel drive using 4.3L/100km and the all-wheel drive consuming 4.4L/100km according to official combined figures.

I drove the GXL all-wheel drive hybrid from Sydney’s CBD to the city’s northern beaches during horrendous peak hour traffic and the trip computer reported an average of 5.3L/100km being used. That’s not bad at all.

The Corolla Cross Hybrid doesn’t require plugging in to an external power source to charge the batteries. Instead the batteries are charged through regenerative braking. That is, you step on the brake pedal and the deceleration energy is converted into electricity and sent into the battery.   

The petrol variant doesn't quite have double the thirst of the hybrid at 6.0L/100km, which is still fairly efficient. 

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.

Toyota has a reputation for reliability and value, but one admirable attribute which should be added to this is also driveability. Nearly every new Toyota SUV I’ve driven in the past three years including the Kluger, C-HR and RAV4 has been an impressive all-rounder on the road.

The Corolla Cross feels a lot like the C-HR and RAV4 to drive in that it handles well, but has a comfortable ride with a secure planted feel on the road.

I drove both the all-wheel drive and front-wheel drive hybrid versions and the petrol variant at the launch and found that while both felt much the same there were two stand-out differences.

The first being the acceleration difference. The hybrid is far quicker off the mark than the petrol version. According to Toyota's claims, the actual 0-100km/h time for the hybrid is 7.5 seconds while the petrol variant can do it 9.0 seconds.

The other way these two Corolla Crosses differ is the smoothness of the hybrid powertrain and the way it moves silently at lower speeds in traffic in EV mode.

Both petrol and hybrid Corollas are easy to drive with steering that’s accurate and light. 

Are there any bad points to the driving? The small back window means rear visibility is restricted although the reversing camera is good. The wing mirrors also appear to be overly large and also obstruct vision slightly, too. 

Other not-so-good points are the relatively noisy petrol engine in all Corolla Cross variants, and the CVT transmission in both also causes the engine to drone.

The Corolla Cross hasn’t been given an ANCAP crash test rating yet, but the advanced safety tech every grade comes with is impressive.

All Corolla Crosses come with AEB that can detect pedestrians and cyclists, and impressively can function between 5-180km/h. There’s also lane keeping assistance, blind spot warning, rear cross traffic alert and adaptive cruise control.

If you step up to the GXL you’ll get auto braking which works while you’re parking and the Atmos gets auto parking.

The impressive airbag tally is the same across the Corolla Cross range, with a total of eight. These include a front centre airbag and driver's knee bag, but there's no side airbags for back seat occupants.

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 Corolla Cross is covered by Toyota’s five-year/unlimited km warranty, which is currently average across the industry. The battery is also covered by that five-year/unlimited km warranty. 

Extended coverage of up to seven years/unlimited kilometres is available if the owner services the vehicle according to the warranty and service book.

The hybrid battery coverage can also be extended to 10 years with an annual health check inspection.

Services are a convenient 12months/15,000km and pricing is capped for five years at $230. That’s outstanding.
