Isuzu MU-X vs Volvo Es90

What's the difference?

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.

More stylish than ever before, as quiet and refined as you'd expect from a luxury car and yet the stand out feature might once again be safety. Despite seemingly every new car being loaded to the gills with safety features, Volvo has managed to demonstrate industry best-practice and leads the way again.

I would encourage engineers from every other car brand to drive the ES90 to learn how to better integrate the modern suite of active safety features like forward collision warning and lane departure warning.

But beyond that, is the ES90 a car worthy of consideration? Well, pretty much everything it does the EX90 does too, so if you prefer an SUV that’s definitely worth consideration. But if you don’t want an SUV, if you prefer a sedan or just love to be different, the ES90 is a very attractive proposition in more ways than one.

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.

Discussing Volvo design will draw different opinions depending on your age. As a millennial, I grew up at a time when Volvos were, to quote a famous movie line from the 1990s, ‘boxy, but good’.

But over the past two decades Volvo has smoothed off those boxy edges and become one of the most style-conscious car companies in the world. It has embraced its now-unique place as a Scandinavian carmaker and uses softer edges and more Nordic design themes (such as light coloured interior woods) to ensure the ES90 is simply a good-looking car.

What it isn’t, at least not technically-speaking, is a sedan. That’s because it has a liftback rear-end design, rather than a traditional ‘three-box’ sedan with a conventional boot. That shouldn’t be a deal-breaker for anyone and it means it’s a far more practical design.

It also sits taller than a conventional ‘sedan’, which is an increasingly common trait for modern European sedans as they try to woo would-be SUV buyers. It’s not a lot, you certainly wouldn’t call it a tall or high-riding car, but it is noticeable.

Ends up as an ‘in-between’ design, neither one thing or the other. The closest thing it reminds me of is the short-lived BMW 5-Series GT, which is damning with faint praise, but it speaks to the challenge of making something that simply isn’t an SUV appealing to the modern SUV-obsessed market.

The very stylish cabin features that previously mentioned light coloured wood (at least in our test car) and that unique Scandinavian look. It’s the closest you’ll get to sitting in a Swedish lounge room on wheels.

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.

In terms of space the ES90 is very generous, which it should be given it's a five-metre long car. There’s loads of room front and the back so you’ll seat four adults in absolute comfort, and can squeeze in a fifth if needed. Thanks to the relatively flat floor, as well as the panoramic roof that can either be opaque or clear, the cabin feels spacious and bright even in the rear.

As for luggage space, the boot measures 424 litres, and obviously it’s very easy to access via the power liftgate. But it’s still not as big as an SUV. The EX90 offers up 655 litres of space in its five-seat configuration. Which is at least a small part of the explanation why SUVs have become the more popular choice.

But what really stands out in the cabin isn’t the space, it’s the technology. The ES90 Ultra’s multimedia system is centred around a 14.5-inch touchscreen that runs all the car’s key functions; you also get a 9.0-inch driver’s display.

Notably, Volvo has opted to offer Google’s operating systems built-in, which means while you can still run Apple CarPlay or Android Auto, if you have a Google account you can sign-in and have your contacts, address book and other details integrated into the car.

It’s a really fast system, too, supported by the most powerful software Volvo has ever put inside one of its cars. Having a big tablet-style screen is great and feels very modern, but if it runs slowly, with lag between commands, it’s not as useful. This Volvo system, particularly the transitions between menus and even the voice assistant, reacts with lightning-fast speed.

Then there’s the sound system we mentioned earlier. It’s a 25-speaker Bowers & Wilkins set-up with 'Dolby Atmos' and an app called Abbey Road Studios. This app has been produced in conjunction with the iconic recording studio made famous by The Beatles. The speakers and the app were all developed together to provide a superior audio experience.

The speakers themselves are incredibly powerful while staying crystal clear, with the Abbey Road app providing the ability to change the sound between 'Modern' and 'Vintage' settings that make you feel like you’re inside a recording studio.

Put simply, it is as impressive a sound system as I’ve ever experienced in a car.

The ES90 range consists of two models at the time of publication both powered by a single, rear-mounted electric motor, with the twin-motor option available on the EX90 SUV currently not offered in Australia (emphasis on the word ‘currently’).

The range begins with the Pure from $88,880, before on-road costs, and is completed by the current range-topping Ultra variant, which we're testing, priced from $107,990, plus on-roads.

That means it’s cheaper than its direct rivals in the luxury electric sedan market. Audi’s e-tron GT starts at more than $200,000, the BMW i5 line-up is priced from $155,900 and the Mercedes-Benz EQE range begins at $134,900. So, even with this more expensive Ultra variant, Volvo has a clear head-start on the competition.

And Volvo hasn't managed that by skimping on standard equipment. The ES90 comes loaded with adaptive air suspension, 22-inch alloy wheels, a comprehensive safety package (as you’d expect from Volvo) as well as an electrochromic panoramic roof, a smart key you can add to your phone and 'Nordico' upholstery - Volvo’s sustainable synthetic leather.

There’s also a 25-speaker Bowers & Wilkins sound system, but more on that later…

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.

As the name suggests, the ES90 Single Motor is powered by a single, rear-mounted electric motor that drives the rear wheels via a single-speed transmission. The motor makes a healthy 245kW and 480Nm, so the 0-100km/h sprint time is 6.6 seconds - sprightly for such a big car.

As alluded to earlier, there is a Twin Motor, all-wheel drive ES90 variant available in overseas markets, with 500kW, but Volvo Australia is yet to confirm when, or even if that will arrive here.

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.

Built on Volvo’s 800-volt electrical architecture, the first Volvo to feature the technology, the ES90 is powered by a 92kWh battery that provides up to 554km of driving range on a single charge.

Volvo quotes an NEDC energy consumption of 18.5kWh/100km, with 300kW DC charging able to take the battery from 10 to 80 per cent in 22 minutes. A full, empty to 100 per cent charge using a 16A outlet will take 10 hours.

It should be noted that the EX90 SUV will be upgraded to the 800V architecture with the 2026 model year introduction.

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.

As you’d expect from a luxury, electric car the ES90 is a quiet and refined vehicle to drive. Being a Volvo, the company has used its experience where it matters, and there is excellent insulation from the outside world. Unlike some EVs that lose the engine and hope that just makes things quieter, the ES90 gives you a genuine feeling of insulation from the exterior hustle and bustle. 

Performance is adequate from the single motor but it’s by no means a sports sedan with only 250kW/480Nm and such a big vehicle. But it has the instant response that is an EV trademark so it has all the performance this type of car and the drivers it will attract would likely need. If buyers start banging on the door for more power, Volvo can oblige, but for now it does the job you expect of a luxury four-door.

While it has the sedan silhouette, the taller body and raised ride height on the air suspension are noticeable. You will find yourself looking up at SUV drivers, but not all of them. It’s roughly the same seat height as you’ll find in a modern small SUV, so a slight elevation rather than a big boost.

The ride is what you expect from this type of car. You can adjust the suspension and steering between ‘soft’ and ‘firm’ settings, but even with the latter selected there is a lot of compliance and the ride remains comfortable.

The steering is fine most of the time, but when you have to do parking maneuvers you certainly notice the ES90's steer-by-wire technology. The steering literally feels like an old computer game steering wheel set-up, with very little resistance as the wheel lightly spins from lock-to-lock. It’s not a bad feeling, but it is a bit odd and takes some getting used to.

The ultimate take-away from the driving experience is just how relaxed it is - quiet and effortless are the two words that probably best sum it up.

This is obviously the area that Volvo is famous for, but with seemingly every other brand forced to raise their own safety features over the years, does the Swedish brand still do anything special on this front?

Absolutely.

Put simply the Volvo suite of active safety systems is better developed and better integrated. Every rival car to the ES90 will have a similar list of features, including adaptive cruise control, forward collision warning, lane departure assist, road sign information and more. But Volvo has made it work so well that unlike rival models, you never even think of turning them off, they don’t beep and bong ad nauseum, they only work if you need them in an emergency - which should be the standard.

One thing to note is the ‘bump’ on the roof (you may see in the images) to house a Lidar system. However, Volvo split with its supplier and has decided to abandon this technology for the ES90. That means the 2026 model year examples will not have the roof bump, but still come loaded with five radars, seven cameras and 12 ultrasonic sensors for the excellent coverage of the surrounding environment.

The only thing that stops the ES90 being worthy of a 10/10 safety score is the lane keeping assist could do with some fine-tuning, as it has a tendency to move in the lane slightly too much.

There is no current ANCAP score for the ES90, but the EX90 SUV does, and given the organisation's previous sharing of scores between different models based on the same core underpinnings, there is no reason to believe the ‘sedan’ wouldn’t be just as safe.

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.

The ES90 is covered by Volvo’s five-year, unlimited kilometre warranty, which is competitive for the luxury market even if it’s shorter than the cover some mainstream brands offer.

Servicing costs are currently unclear, at the time of publication. Volvo Australia typically offers five-year servicing plans for its models but is yet to finalise the cost for its electric vehicles.

Despite its long history in Australia, Volvo still has a relatively small footprint in this country with only 28 dealers/service centres spread across the country. However, more are planned to expand that coverage in the coming years.
