Mazda CX-90 vs MG Im6

What's the difference?

There are many reasons I quite like this CX-90. It sells the plush luxury promise when it comes to its interior and design, it feels big and purposeful, and has a refreshingly minimalist approach to its cabin tech. As a seven-seat SUV it’s particularly impressive, with plenty of amenity and a third row that can genuinely fit an adult in comfort.

However, there are areas where it could use more polish, from the drivetrain to the ride, and it ultimately strikes an odd point for price and ownership which feels lost between the premium segment and the mainstream rivals.

If you’re a long-term Mazda owner, I still think you’ll love it, and this Touring grade is definitely the best value in the range. It offers the lion’s share of equipment at a price more comparable to Mazda’s traditional mainstream rivals.

A super solid first outing from the IM brand. Don't let the pricing fool you, there is still bang for buck on offer in the IM6 Performance, even if it at times feels a bit too digital for my tastes.

The CX-90 is an impressive car to behold. Moving things onwards and upwards from its CX-9 predecessor, the CX-90 is bigger and even more refined in a lot of ways.

Mazda’s signature design language has evolved into something a bit beefier, trading out the delicate sharp angles and chromes of its front-wheel-drive predecessors for something a bit more upright, with a wide stance and tough proportions.

The long bonnet and expansive body panels stress the long-engined, fluid nature of this car’s design language. It certainly gives it a more premium vibe than the boxy American-influenced style of the Hyundai Palisade, and leans more European than the science-fiction styling of something like the Kia Sorento.

If anything, there’s some clear BMW influence in the shape of the tail and light fittings. Light lashings of chrome keep it in-line with Mazda’s previous design language, and on this base model at least, plastic claddings over the arches toughen it up a bit.

Inside is plush. In fact, it’s treading on Lexus territory when it comes to the design and feel of the seats, dash, doors and there are even padded leather touches down the sides of the centre console for your knees to rest against. Even the standard leather seats are nice (with softer Nappa leather available on higher grades), and I actually find the somewhat monochrome interior treatment on our test car to be the most modest option. It’s off-set by silver trims and a touch of chrome in the steering wheel and doors.

The dash is in a more traditional style (again, it feels influenced by BMW here) with a padded insert across the front, inset vents and a climate control panel leading down to a nice wide console with tasteful patterned trims, and an electronic shifter. The screen in this base car is of modest dimensions compared to most cars today, but those who aren’t sold on giant touchscreens will love it.

Even the digital dash elements are tastefully executed, although they’re not particularly customisable, which is a shame. 

I feel almost mean saying this, because there will be plenty of people who like the way the IM6 looks, and I don’t want to rain on their parade. But… I’m not one of them.

It reminds me a bit of the pre-facelift Tesla Model Y, in that it’s largely feature-less and a bit blobby, and there’s not a sharp angle anywhere to be found on the thing. Premium to me means powerful and assured — picture just about any Audi — whereas I just find this a bit bland and soft.

Anyway, I do like the big alloys, the insulated glass roof and the light treatment front and rear.

And I like the cabin. The seats aren’t leather, but they’re super thick and comfortable, and there is a genuinely premium air in the cabin, helped by the acreage of screens and the quality elements, like the little door panels.

The doors unlatch electrically, matching the pop-out door handles outside, but they can be a bit fidgety. Someone from MG told me how they worked (you kind of cover the handle and let the door come to you) but I watched everyone else who tried to open them struggle. If you're at the point where you have to explain how a door handle works, you might have over-egged the pudding.

The second screen below the main one acts a bit like a mobile phone. You can alter your home screen widgets and access the main menu, even as Apple CarPlay is synched at the top. You’ll get used to it, I’m sure, but I found it to be a bit fidgety.

Actually it reminds me a little bit of the Lexus trackpad, or whatever that hateful system was called, where you controlled the main screen via a little mousepad thing, though happily it’s nowhere near as annoying as that was.

The CX-90 is enormous, but despite its long bonnet, it feels on the inside like it makes good use of its dimensions.

Up front, it’s easy to find a seating position thanks to an array of adjustability, from the seats to the telescopic adjust for the wheel, and the cabin is wide and tall enough to accommodate pretty much anyone with ease.

Unlike some Mazdas which have a strange zoom-factor on their rear vision mirrors, the CX-90 doesn't have this problem, and visibility generally out the windows is impressive. I can see the long, tall bonnet and cosy dash design creating visibility issues for shorter drivers, however.

Padded materials are everywhere they should be (and more), and when it comes to storage there’s a large bottle holder in each front door, two more cupholders in the centre console (with a flip-out cover), a split-opening centre console box (which hides USB-C connections, great for cable management) and a wireless charging bay up front below the climate unit.

It’s rare these days to see a full array of physical buttons and toggles for a dual-zone climate set-up, but the Mazda has the whole lot. It’s a breeze to adjust on the fly and integrates into the design in a subtle way.

It’s also worth calling out the multimedia screen isn’t a touch unit. Instead, you need to control it through a handful of buttons and a rotary dial on the centre console. It’s nice to have a physicality to it, and it works well for the relatively simple base operating system, but it’s a clumsy way to interact with phone mirroring.

In my experience Apple CarPlay has simply too many icons and menu features to work around with a dial-operated system, to the point where it’s distracting to use on-the-go (thus, defeating the purpose of having physical controls).

The second row is a real highlight. Set to its default position, I have leagues of legroom behind my own driving position (at 182cm tall). Again, heaps of width and headroom here, and even the huge rear doors open nice and wide, which should make loading luggage and fitting child seats easy.

The seat trim is just as good as it is in the front, with decent side bolstering, and top-notch amenities, with shades built into the windows, decent-sized bottle holders in each door, a further two in the drop-down armrest, soft pockets on the backs of each front seat, and a separate climate zone with independent temperature and fan speed controls.

There are two adjustable air vents with a lock-off, as well as two USB-C ports for power. Top marks.

The third row is usually where things get tricky for SUVs like this, but the CX-90 isn’t out of tricks yet.

Access isn’t the easiest. The second row can fold forward, but the left over aperture for clambering in, even though the doors are quite large, isn’t great, which will make it a no-go for anyone with mobility issues.

However, once you’re back there, I was surprised to find a full-sized adult like me can fit in relative comfort. With the second row set as far back as it can go, my knees are hard up against the back, but when rolled forward for more third-row space, there's still plenty of room in the middle. I was left with ample room for my knees and feet in the back seats. The seat trim also offers decent padding and comfortable trims, which is rare for most three-row SUVs, and while you wouldn’t want to be too much taller than me, the roof was just tall enough to have a little airspace above.

The armrests are hard plastic, unfortunately, but offer two large bottle holders on each side, as well as a USB-C port, and vents with decent air flow, which is again, quite rare for a three-row SUV.

I’d go so far as to say this is one of the best SUV third rows I’ve been in when it comes to space, comfort and amenity.

Now for the luggage space. I was pleased to find, even with the third row up, I could fit the largest (124 litre) CarsGuide luggage case with room to spare on either side. Officially, space here is 257L, but it’s rare to fit a case this size in a three-row SUV.

With the third row folded down, space comes in at 608 litres, which is on-par for this segment, and with the second and third row down, it tops out at 2025L.

With such space on offer it’s probably worth keeping in mind the payload, which is 580kg, and for those who want to add a trailer to the mix, the maximum towing capacity is 2500kg braked or 750kg unbraked for the 50e petrol straight-six versions like the one we’re testing here.

The IM6 measures 4904mm long, 1988mm wide and 1669mm tall, and it rides on a 2950mm wheelbase, with IM describing it as a "mid-large SUV", though I expect it will be classed as a medium SUV Australia.

That said, ICE and EV mid-size electric SUVs are not cut from the same cloth, with the latter making use of a flat floor to maximise space. And so it is with the IM6, where backseat room is pretty damn impressive. I’m 175cm, and I had no problem at all with legroom or headroom, plus the same plush seats from up there are in the back, too.

There are also air vents but no temperature controls, and while there are USB ports, there is no regular household-style plug in the cabin. 

The glass in the windows is laminated, while the roof is double glazed, which MG tells me is Australian summer-proof, but I guess we'll know for sure in a couple of months.

There’s no shortage of cargo room either. There’s a 32-litre frunk up front, and there’s 646 litres in the boot with the rear seats in place. They’re 60/40 split, and if you drop them, luggage space grows to 1621 litres.

The towing capacity is a braked 1500kg, too, but I don’t expect to see many of these towing a camper trailer around.

Premium play means more premium prices, and my IM6 Performance will set you back $80,990 on the road. That might have just sent your eyebrows skyward, but keep in mind it’s faster than some Ferraris, and is swimming with high-end tech, so the bang-for-buck factor is actually still pretty good.

There are cheaper ones, too. The single-motor Premium grade is $60,990 drive-away, albeit with less power and slower charging. Then there’s the Platinum, with a bigger battery and faster charging, which is $69,990

The Performance, though, gets everything IM has to give, including an 800-volt architecture, which means super-fast charging, as well as twin motors, brutal acceleration, a decent driving range and adaptive air suspension.

Elsewhere, you get LED lighting, a big and insulated glass roof, and 20-inch alloy wheels. Inside, there are thick and soft synthetic leather seats that are heated and cooled in both rows, a banging 20-speaker sound system, and wireless charging to pair with wireless Apple CarPlay and Android Auto.

There’s also 'active noise cancellation', and a seat-aware digital assistant which is about the best, and fastest, I’ve ever used. The IM6’s speaker system can locate where a voice is coming from, so any passenger can use the assistant. For example, if you’re in the backseat and say 'hey IM, lower my window', only your window opens. It’s a technology that I specifically remember the German brands crowing about not so long ago.

There’s also a 10.5-inch central touchscreen that controls much of the vast 26.3-inch screen that runs from in front of the driver to the centre of the cabin, as well as clever little magnets embedded in the dash in front of the driver, as well as in the back of the front seat headrests, that are designed to hold phones, iPads or other little accessories.

Also cool is the IM6’s self-parking tech, but there’s also a relatively useless crab walk function, which leans on the rear-wheel steering system to drive diagonally at slow speeds. I’m still not entirely sure when you’d use that one, to be honest.

Honestly, it’s a lot of stuff, and a lot of tech.

The CX-90 gets a bit exciting under the bonnet with its big 3.3-litre in-line six-cylinder turbocharged petrol engine. It produces a whopping 254kW/500Nm, well above par compared to its mainstream rivals.

This engine is mated to an eight-speed automatic transmission. This is no run-of-the-mill transmission though. Instead of the usual smooth hydraulic coupling this style of transmission is known for, the Mazda uses a hybridised single clutch set-up instead.

This is in the name of efficiency. A single-clutch plate has less loss, and is therefore more fuel efficient, with a small electric motor helping to push things along as part of the mix.

The catch is, like the sometimes-derided dual-clutch automatics, it’s not as smooth to operate. More on this in the driving section.

Efficiency – What is its fuel consumption? What is its driving range? 8/10

As a result of this unusual transmission set-up, fuel efficiency isn’t bad for such a big and powerful engine, and for such a large vehicle.

The official combined fuel consumption for the CX-90 G50e is 8.2L/100km, which is already impressive, and in my week with the car over a few hundred (mostly urban) kilometres it landed close, at just 8.9L/100km.

It’s seriously impressive and runs rings around the six-cylinder Hyundai Palisade (10.7L/100km combined) while producing significantly more power than the more efficient Toyota Kluger Hybrid (5.6L/100km). On the flipside, you’ll need to fill its massive 75L fuel tank with mid-shelf 95RON fuel.

This is the real party trick of the IM6, because there’s a nuclear power plant under the metal somewhere. All up, the twin-motor setup produces a total 578kW and 802Nm, though I suspect you’re never accessing all the grunt all at once. Still, 100km/h zips by in 3.4 seconds, and the top speed is 239km/h. For the record, that’s exactly as fast the Ferrari Roma Spider I recently handed back, so yeah, it’s properly supercar quick.

For all its clever, efficient drivetrain, the CX-90 has a bit of a mixed drive experience. Initially, it comes off as impressive. It’s plush and quiet from behind the wheel, and the primarily rear-drive nature of its drivetrain gives it the big premium steering response missing from its mostly front-drive rivals.

The flaws with its tricky transmission quickly become evident, though. The clutch constantly needing to engage in stop-start scenarios makes for a slightly jerky and uneven experience, similar to the feel of a dual-clutch auto, particularly in traffic, while the at-speed gear shifts, which in a dual-clutch tend to be much smoother are telegraphed more physically by this Mazda system.

As evidenced by the actual fuel consumption, it’s clear this system does what it sets out to, and it even feels like it could be significantly better, but Mazda will need to invest some time in calibration. For what it’s worth, it feels better than its original implementation I drove at the launch of the CX-60, which was the first car to get this system.

A subsequent software update has solved some issues, but it still can’t compare to a regular auto when it comes to smoothness.

However, the engine is immensely satisfying. The big six has a low roar when pushed, and motivates the big CX-90 with ease when you step on it. It pairs nicely with the weighty steering to make for a car which feels purposeful and satisfying to steer when it gets going.

In this sense it nails the brief of elevating Mazda out of the regular crop of front-drive seven-seat SUVs, giving it a distinct and more premium edge.

As also noted with the CX-60 though, the CX-90 has the same issue with its ride quality. It’s a little too hard to give it the kind of refined response to road imperfections we’ve come to expect from brands like Lexus and BMW. The firm response to the road helps this big heavy SUV feel controlled in the corners, but it doesn’t deal with suburban bumps how it should.

Larger hits in particular are often communicated to the cabin. The CX-90 is better than its smaller CX-60 sibling, which went so far as to have its rear dampers recalled, but the brand is even considering similar updates to this large SUV, so keep an eye out.

While this version of the CX-90, the base Touring with its smaller alloys and larger tyres, is more comfortable than any other Mazda on this new platform I’ve driven, it still leaves room for improvement.

It’s a shame, because otherwise the CX-90 is a lovely and luxurious SUV to drive, with a quiet, plush interior and a satisfying engine. It’s so close to greatness that it’s frustrating.

First things first, don't get too distracted by the word "performance" here. The IM6 doesn't act like a performance car, it feels bit too plush, and bit too digital, for that.

But that's not necessarily a bad thing. Performance cars are often loud, raucous and uncomfortable, and the IM6 is none of those things. Instead, those mountains of power and torque make silky, silent progress absolutely effortless, which feels pretty premium to me.

MG makes a big deal of how much work went into insulating the cabin from noise – with active noise cancellation joined by double-paned insulated glass – and it is a properly calming and quiet space.

Also strong is the suspension, with the adaptive air setup soaking up most bumps and bruises, but I found it can clang over really solid bumps, sounding like it's bouncing off a stopper. The steering is solid, too, with a nice weight, if not overly talkative in the feedback department, while the rear-wheel steering helps eat into the turning circle for tight three-point turns.

The downside, though, is that it all feels a little too digital, and like there's been a little too much overthinking gone into it. Having to push a button to see behind you in a hurry is bonkers (see my explanation in the Safety section below), and the secondary screen is more annoying than intuitive. And there were several bings or bongs I couldn't even identify. All of which interrupts the otherwise calming nature of the drive experience.

There is a long list of safety aids on the IM6, and I won't detail the lot here. But I will call out a couple of curious mentions.

As always, the driver distraction warning is annoying, but can be switched off. And MG also counts the IM platform, or what it calls a digital chassis, as part of the safety offering. It has its own digital brain that adapts the air suspension, the rear-wheel steering and the active safety kit on the fly.

The other curiosity is the weird way you see out the back. Rather than fit a digital rear-view mirror to counteract the almost non-existent rear vision, you instead push up on a little toggle on the steering wheel to bring up a live view of what's happening behind you on the central screen.

The usual five-year and unlimited kilometre warranty applies to the CX-90 range, with a matching five years of roadside assistance.

Servicing is required once every 12 months or 15,000km, whichever occurs first, and a schedule of costs on Mazda’s website extends to seven years. Over the first five years, prices fluctuate between $469 and $1304 annually, with an average yearly cost of $693.30. The price puts this big-engined Mazda up the premium end of mainstream automakers when it comes to service costs.

The IM6 is covered by a five-year, unlimited-kilometre warranty, rather than MG’S 10-year term. Capped-price servicing is offered for the first five years, with your total bill just under $3000. The service intervals are 20,000kms or 12 months.
