Mazda CX-5 vs Isuzu MU-X

What's the difference?

The Mazda CX-5 Evolve kicks some goals and with its comfortable on-road handling, robust safety equipment and practical interior, it’s still a solid choice for families looking for a mid-sized SUV. The only thing it’s missing is a hybrid powertrain, which would make this already well-rounded package even more compelling.

The MU-X has plenty of appeal as a daily driver – dependable and it’s a proven 4WD wagon.

Does the 2.2-litre engine add anything substantial to the mix?

Well, it's better than the 1.9-litre, that's for sure, and there's a lot to like about this MU-X in terms of its off-road capability, driver-assist tech, standard features and all-round driveability. And, while the LS-T lacks the top-shelf polish of the X-Terrain, it’s still an appealing potential purchase.

But the 3.0-litre option is better because while the 2.2L is very effective off-road and general day-to-day driving, it lacks grunt and has to work that much harder and is that much noisier under load than the 3.0-litre in most driving scenarios, including 4WDing.

The next-generation Mazda CX-5 is bigger than before, but it retains the sleek body lines and understated styling that have made it such a handsome SUV. The wider front end and repositioned grille give it a more purposeful look than the outgoing model, while the 17-inch alloy wheels keep things suitably restrained.

Inside, the cabin doesn’t feel too basic despite the cloth upholstery. There are plenty of soft-touch materials, a pleasant dashboard and some new technology, including the 12.9-inch multimedia display. You lose most of the physical buttons, though, so there’s a little less of that traditional Mazda tactility.

The fabric seats are cosy and the extra interior space is definitely noticeable. Overall, there is still an understated elegance to the CX-5’s cabin.

In terms of appearance, the MU-X remains largely unchanged from the most recent iteration. And that’s a good thing. It’s blocky enough to be recognisable but sleek enough to remain inoffensive. Worth noting the door handles, window trims, front fender accents, roof rails, and side steps on the LS-T are gloss black.

Inside, nothing much has changed (other than a newly-introduced idle start/stop button) and, as such, the MU-X retains a low-key familiarity that makes it a comfortable space. Generally, design-wise, the MU-X more than holds its own against the likes of the Toyota LandCruiser Prado and Ford Everest.

The front seats are a particularly comfortable place to spend time, with wide seat bases and plenty of elbow room. Getting in and out is easy thanks to the wide door apertures and 205mm of ground clearance and there’s enough space to settle in for a longer journey.

There’s also plenty of useful storage up front, including a large glove box, dual-opening centre console, cupholders and bottle holders, plus a dedicated phone tray with wireless charging. You get a 12-volt socket and two USB-C ports for keeping everything else topped up.

The 12.9-inch multimedia screen replaces Mazda’s familiar rotary selector with touchscreen operation, which I find easier to use. The updated operating system takes a little while to get your head around and there’s no native sat nav, but otherwise it feels functional and fresh for the new-generation model. Wireless Apple CarPlay and Android Auto are standard, with CarPlay maintaining a solid connection throughout my week.

The extra size of this next-generation model is more noticeable in the back, where improved leg- and headroom is good news for taller adults on longer trips. The rear doors open to almost 90 degrees, making it easier to access the ISOFIX child-seat mounts and three top-tether anchor points.

There’s not a huge amount of extra family-focused kit back in the rear row, but you do get directional air vents, storage bins in each door and a centre armrest with cupholders. My nine-year-old was comfortable, although he did point out the lack of a charging port during a road trip.

And, as a parent, I had one other gripe: keeping the fabric seats clean from my kid’s shoes in rainy weather. Let’s just say some seat covers might be a worthwhile investment.

The boot offers up to 466L with all seats in use. That’s not the largest capacity in the class, but it was more than enough for my little family of three this week. I like the level loading floor, although the boot itself is quite tall, which can make lifting heavier items in and out a little awkward.

I’m also pleased to see a spare tyre, even if it is only a space-saver. And while a powered tailgate would be handy, at this price point I don’t think you’ll really miss it... until you’re standing there with your hands full!

The interior has a familiar and practical feel about it and the cabin is an easy space in which to become comfortable. Controls are easy to locate and operate and charging options are numerous – a mix of USB-A, USB-C (front and second row) and 12V.

Storage places include recesses for the bits and pieces from your pockets, a deep-ish 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 also cupholders either side of the third row.

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

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

My camera guru/photographer/sergeant-at-arms, Glen Sullivan, reminded me that the third-row seats don’t have ISOFIX or top-tether points for child seats. Thanks, mate.

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 stowed away.

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’s full-size spare (bravo!) is attached to its undercarriage.

The new MU-X with a 2.2-litre, four-cylinder, turbo-diesel engine is available with a 4×2 or 4×4 drivetrain in several variants. Don’t worry, the 3.0-litre is still in the line-up.

Our test vehicle has the 2.2L and, it is priced at $71,400 before on-road costs.

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), heated front seats, a 7.0-inch driver display and 20-inch alloy wheels shod won 265/60R20 Bridgestone 684II HT tyres.

It also has white ambient interior lighting, remote engine start, rear privacy glass, power-folding and heated door mirrors (with side cameras) finished in gloss black, and leather-accented upholstery with grey stitching and synthetic leather on the door trims and centre console.

Exterior paint choices on the MU-X LS-T include 'Mineral White', 'Basalt Black mica', 'Moonstone White pearl', 'Magnetic Red mica', 'Neptune Blue mica', 'Mercury Silver metallic', and 'Obsidian Grey mica'. Anything other than standard Mineral White costs an extra $695.

The CX-5 is all-wheel drive and powered by a 2.5-litre four-cylinder petrol engine producing 132kW of power and 242Nm of torque. It has a braked towing capacity of up to 1800kg, giving you the option of some light towing on the weekends, while the six-speed automatic transmission shifts smoothly through its gears.

But there’s no escaping the fact that most of its key rivals now offer hybrid powertrains, and you can feel the absence of one here. The CX-5’s petrol engine is perfectly capable, but it doesn’t have the same efficiency advantage that many buyers in this segment are increasingly looking for.

This MU-X has a 2.2-litre, four-cylinder, turbo-diesel engine, producing 120kW at 3600rpm and 400Nm between 1600-2400rpm and it’s matched to an eight-speed automatic transmission.

Worth noting the 3.0L MU-X has a six-speed auto and produces 140kW (at 3600rpm) and 450Nm (1600-2600rpm) while the outgoing 1.9L MU-X has a six-speed auto and produces 110kW (3600rpm) and 350Nm (1800-2600rpm).

While the 3.0-litre has always been unstressed in most driving scenarios – even low-range 4WDing – the 2.2-litre feels underpowered. More about that in the ‘Driving’ section below.

The MU-X has a part-time 4WD system which includes a dual-range transfer case (with high- and low-range 4WD) and a rear diff-lock. The driver is able to shift from 2H (two-wheel drive, high-range) to 4H (4WD high-range) while on the move up to speeds of 100km/h. The diff-lock may only be engaged when the vehicle is in 4L (4WD low-range).

The MU-X also has a switchable terrain mode system which tweaks the engine, transmission and traction control to suit the driving conditions. 'Rough Terrain' mode, like a steroids-enhanced off-road traction control, is king of these modes when you’re off the bitumin.

The CX-5 has a 58-litre fuel tank and claimed combined cycle (urban/extra-urban) fuel consumption of 7.4L/100km, giving it a theoretical driving range of up to 783km. That’s a solid range for a family-sized SUV and means you won’t be constantly thinking about your next fuel stop.

My real-world fuel use settled at 7.8L/100km after a week of longer highway stints and urban trawls, so it’s not too far off Mazda’s official number.

Still, this is where I’d like to see a hybrid powertrain join the CX-5 range. The fuel economy is reasonable, but with so many rivals now offering hybrid options, Mazda is starting to leave some efficiency gains on the table.

Official combined cycle (urban/extra-urban) fuel consumption for this MU-X is 6.7L/100km. The 1.9L MU-X offers 7.4L/100km while the 3.0L offers 7.6L/100km.

Actual fuel consumption on this test was 8.7L/100km.

The MU-X has an 80-litre fuel tank, so, going by that on-test fuel consumption figure, you should be able to get a driving range of about 920km. But remember, your fuel consumption may be completely different to mine because chances are you'll have friends, family pets, sporting equipment, camping gear, the whole kit and caboodle on board. I've only been carrying vehicle recovery gear, MaxTrax, and a first-aid kit, so I haven't had a huge amount of weight on board.

The CX-5 feels composed around town, with power delivered smoothly for everyday driving. But when you need to punch it off the mark, there’s some noticeable lag, and you have to work the engine harder to find the power when tackling a steeper hill at higher speeds. It’s capable enough, but it can feel like you’re asking a little more of it than you should.

The suspension has a firm edge to it, but I like how responsive the steering feels. The CX-5 is genuinely enjoyable through corners, with a dynamic feel and very little body roll.

The cabin is also impressively quiet, with minimal road or wind noise creeping in at higher speeds. Visibility is good through the front and sides, although the A-pillar can get in the way at times.

The reversing camera provides a clear view, while front and rear parking sensors make manoeuvring easier. Overall, it’s not a difficult SUV to park, despite its larger dimensions.

Before we launch into the off-roading section of this test, it’s worth noting the MU-X has always been decent on-road; composed, reasonably refined (for a 4WD wagon, anyway) and comfortable. And thankfully, with the 2.2-litre engine, not all of those characteristics have been thrown out the window.

It is quite noisy, especially under pressure when you have to do some heavy acceleration or when you have a bit of gear on board. When it has to work that bit harder than it usually does, it can become quite noisy. Admittedly, the 3.0-litre MU-X is also quite gruff, but there's an edge to the roughness in the 2.2-litre that is very noticeable on road.

This MU-X is quite sluggish off the mark, exhibiting a disconcerting lag under heavy throttle from a standing-start. And it’s far from the most dynamic vehicle to drive. But it has a tractability about it that manages to mostly negate these flaws.

Otherwise, the new eight-speed auto deserves credit as it’s slick and smooth in application and feels right at home in this wagon.

Now to off-roading. The MU-X is still very capable. In fact, even with the 2.2-litre engine, it remains one of the better-performing 4WD wagons straight out of the dealership, in terms of pure off-road capability.

The 3.0-litre MU-X is not the torquiest in this segment, but it offers ample pulling power available across a wide rev range – count on peak torque between 1600rpm and 2400rpm – and it delivers that pulling power in an even-handed fashion. The 2.2-litre MU-X has to work harder than its stablemate, and it’s noisier and harsher.

However, those characteristics don’t take away from how effective this MU-X is because it offers impressive off-road performance. It still has a decent amount of low- and mid-range torque, which makes dirt-road cruising and low-speed 4WDing easy.

The MU-X has part-time 4WD with high- and low-range 4WD gearing, a rear diff lock and overall it retains all of that off-road capability the 3.0-litre MU-X has been renowned for – so you don't lose any efficacy there.

The line-up’s off-road traction control system, which once was a bit patchy in its effectiveness, has gone through a couple of phases and it’s been recalibrated/tweaked over the years and it is much better now.

Of course, the MU-X also has Isuzu’s much-vaunted Rough Terrain mode (a form of early-acting off-road traction control which converts lost grip into torque for the wheels with grip), and it is smooth and effective, giving the driver better overall control in challenging terrain.

Some of this MU-X’s listed off-road angles appear shallower than the 3.0-litre MU-X’s – approach: 23.9 (3.0L = 29.2), departure: 26.4 (3.0L = 26.4) and ramp-over: 19.6 (3.0L = 23.1) – but, even if that is the case, it has very similar driving characteristics in low-speed, low-range four-wheel driving to its 3.0-litre stablemate.

If you drive with control and consideration, you shouldn't have any trouble tackling light to moderate 4WDing in this MU-X. It could even, if push comes to shove, handle challenges that may be considered by some to be on the edge of hard-core 4WDing – for a showroom-standard 4WD wagon anyway.

Ground clearance is 235mm and wading depth is 800mm, so there’s an adequate amount of clearance to work.

The MU-X – with a turning circle of 11.6m and a kerb weight of 2130kg (3.0L = 2185kg) – feels quite nimble on bush tracks.

This wagon’s wheel travel – how far the axle can move up and down relative to the chassis – has more than an adequate amount of flex, stretching its tyres close, if not all the way, to the dirt.

A noticeable trade-off is its 20-inch wheel-and-tyre combination, which is best suited to sealed surfaces and so are far from ideal for dirt-track touring. There’s an easy remedy, though. Buy a set of decent all-terrain tyres on 17- or 18-inch rims to replace the showroom-standard 265/50R20 Highway-Terrain tyres. If you are using your MU-X, avoid dropping pressures too much because you’ll risk sidewall pinches and punctures on these low-profile road tyres.

In terms of packability: the 2.2L MU-X has a listed payload of 670kg, whereas the 3.0L version offers 615kg.

The 2.2L MU-X can legally tow 750kg (unbraked trailer) and 3500kg (braked), so theoretically you can tow the same load as a 3.0-litre MU-X. But, as mentioned, the 2.2-litre engine feels underpowered, even in general day-to-day driving, so with a load and/or towing that’s an added burden.

For reference, the 2.2L MU-X has a listed gross vehicle mass of 2800kg and gross combined mass of 5900kg.

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 front side, dual full-length curtain, front knee and centre (far-side) - and a comprehensive suite of driver-assist tech including AEB, adaptive cruise control, lane-keep assist, lane departure warning, a digital reversing camera and a tyre-pressure monitoring system.

Remember, the third-row seats do not have ISOFIX or top-tether points for child seats.

The CX-5 is covered by Mazda’s five-year, unlimited-kilometre warranty, which also includes five years of roadside assistance. It’s a solid offering, although longer warranty terms are becoming increasingly common in this segment.

Servicing is reasonably priced at around $440 per service over seven years, and the intervals are well spaced at every 12 months or 15,000km, whichever comes first. That should make ongoing ownership relatively straightforward for families.

The MU-X has a six-year/150,000km warranty and seven years of roadside assistance. Unlimited km in the warranty 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 MY24 and later vehicle models (up to 5 years/75,000km – whichever occurs first) – at a flat price of $469 for each service.

Isuzu Ute Australia has a nationwide network of more than 160 dealer sites.
