Mazda CX-90 vs Mercedes-Benz EQB

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.

I really liked the combustion version of this car, the GLB, for its funky style and flexibility and I was pleased to find how easily Mercedes has made the conversion to a fully-electric layout for the EQB.

Despite a tall price, the EQB 350 is a compelling option for those seeking something a bit more luxurious than the Tesla Model Y, something a bit larger than the Volvo XC40 Recharge, and something a bit smaller than the Audi e-tron or the EQC.

The main trade-off for this 350 variant is the loss of the seven-seat layout in favour of more performance. Instead it offers a huge boot, has a sufficient range for city-based buyers, and offers surprising levels of fun, too. 

Just make sure you’ve considered its rivals which may potentially offer more range or features for the same money.

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. 

The EQB has a very predictable design in that it doesn't stray from the combustion car’s formula. At all.

The only evidence from the outside this is the electric version is the blanked out grille, and closer observers might notice the rear light bar which cuts across the boot lid is different from the split tail-light design which appears on the combustion car.

Still, to my eyes, the GLB is a cool design with its upright boxy look bucking the curvaceous trend of most EVs, and, indeed, the rest of the Mercedes line-up. 

Its rebellious streak makes it one of the most appealing SUVs in Mercedes’ current range, and it comes with a bit of toughness which is missing from the EQA. 

If nothing else, it’s a completely different look from Tesla’s amorphous Model Y, and this may be enough to appeal to some.

Inside is identical to other Mercedes models which sit on the MFA2 small car platform, immediately setting itself apart with the big high-resolution screens, glitzy ambient lighting, as well as an abundance of chrome and gloss black.

It’s designed to impress from the first time you hop in, and there’s no doubt it does, but it may be a bit over-the-top for some, particularly fans of the more conservative Mercedes designs of eras past.

The chrome in particular becomes a bit of a problem, as it has an annoying habit of catching the reflection of the sun and sending it directly into the driver’s eyes.

It all feels as plush as a circa-$100,000 luxury car should though, with the ‘Artico’ seat trim being one of the better synthetic options on the market, and soft-touch surfaces throughout the cabin selling the Mercedes promise. 

The GLB toughness is even reflected in the chiselled out finishes in the door, dash, and centre console, helping to set it apart from the tamer EQA.

The software is also fast, high resolution, and well presented, which bodes well given the amount of screen real-estate, and the amount of customization is impressive, too.

Again, there are many who will prefer its look and feel to the Apple-store chic of the Tesla Model Y, or the pared back Scandinavian approach of the XC40 Recharge, but also those who won’t. Like many new Mercedes products, it continues to polarise buyers.

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.

This should be the GLB’s calling card. It’s a car with an ideal footprint, not as wide or as long as most mid-size SUVs, whilst also offering a larger cabin and boot.

The big drawback for this variant in particular is the lack of a seven-seat option, as the all-wheel drive requires the under-floor space which is required to give rear occupants legroom. 

It’s a shame, too, because I found the two rear seats in this car’s GLB combustion equivalent to be surprisingly accommodating for even adults.

As a result of these missing seats, though, the full volume can be exploited in the boot, which comes in at a whopping 495 litres.

It’s rivalled by the Model Y, which also has a cavernous boot, although it has a much larger storage area than the Volvo XC40. 

As an added bonus, there is a decent under-floor storage area which has enough space for all your charging cables, although there is no so-called ‘frunk’ with what is normally the engine bay taken up by cooling and auxiliary hardware. 

At first glance there’s so much going on under there, you’d be forgiven for thinking the EQB has an actual engine!

The cabin is also enormous as well as configurable. The EQB has massive rear doors (as it’s designed to be a seven-seater) to make it easy to get in and out of, and once you’re settled in, the amount of space for me (at 182cm) behind my own driving position is very impressive, with ample leg, arm, and headroom.

Rear passengers score the same nice synthetic leather seat and door trim as the front passengers, a bottle holder in each door, as well as two in a flip-out caddy on the drop-down armrest, two nets on the backs of the front seats, dual adjustable air vents, and power outlets on the back of the console. There is also a separate section of the split sunroof to benefit those in the back seat.

Up front the cabin is equally flexible, although it immediately seems odd that the front seats are manually adjustable. Almost unforgivable in a $100,000 car. 

At least the trim is comfortable, and again, the space is configurable for people of all shapes and sizes. 

Storage options include large bins in each door, a split-opening armrest console with USB-C outlets inside, a slide-open area underneath the climate unit, which houses a wireless phone charger and additional power outlets, as well as the usual glove box arrangement. 

Soft trims continue into the doors, although one small annoyance is the excess of chrome trim which has the unfortunate habit of reflecting harsh Australian sun into your eyes if it hits at the wrong angle.

The software is nice and quick, but can be cumbersome and over-complicated to operate at times, particularly when using the centre touchpad, or adjusting the dash with the small touch elements on the wheel. 

It is also notable the Apple CarPlay as-tested only took up a centre portion of the screen, and is not set-up for widescreen mode to take full advantage of the hardware.

Minor complaints aside, though, the EQB follows its combustion GLB twin in having by far one of the most flexible and configurable cabins in its class.

The EQB range kicks off from $87,800, before on-road costs, for the base 250, but the car we’re looking at for this review is the top-spec 350 4Matic, which wears a price-tag of $106,700.

There’s no doubt it’s a hefty price, even for an EV, and especially for a sort-of ‘small’ SUV. There’s more to consider, too. As I mentioned in the intro, the all-wheel drive system precludes the seven-seat layout in this top-spec car, and it has less range than the front-wheel drive model, too, dropping from 371km to 360km.

On the upswing, the dual-motor powertrain is far preferable to the so-so front-wheel drive option, and the 350 also gains an AMG-spiced bodykit and flat-bottomed steering wheel, as well as a panoramic sunroof.

Outside of the extra flair, the EQB 350 is almost as well equipped as you could hope, with the flashy dual-10.25-inch 'MBUX' screen set-up, Nappa leather steering wheel and interior appointments with Mercedes’ signature 'Artico' synthetic seat trim, LED headlights, ambient interior lighting with fully customisable RGB controls, dual-zone climate, a wireless phone charger, 20-inch alloy wheels, as well as keyless entry and push-start ignition.

Given the EQB’s dimensions it would seem its most direct rival is the Tesla Model Y, although it may not be a favourable comparison. 

At over $100,000 the EQB 350 is still more expensive than the top-spec Model Y Performance, which is even more powerful than our Merc here.

Other more indirect rivals include the Volvo XC40 Recharge (from $74,490 in twin-motor form), or less performance-oriented Lexus UX300e ($80,691 for the top-spec Sports Luxury), although neither are as large as the EQB, and the Lexus has about half the performance.

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.

While the EQB 350 loses its valuable third-row seats, it gains a much more impressive drivetrain than the lesser EQB 250 variant. 

While that car has a so-so front-motor set-up producing 140kW/385Nm, the top-spec 350 sports a much more capable 215kW/520Nm dual-motor system.

This allows a 0-100km/h sprint time of 6.2 seconds, and while it’s not as fast as the entry-level Tesla Model 3, it’s still impressive for a 2153kg SUV.

The all-wheel drive capability also adds a level of confidence which can’t be matched by a front-drive, more on this in the driving section of this review.

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.

This is where the 350 version of the EQB shines. This car is a beast to drive with plenty of power available at your right foot, and incredible amounts of traction to match from its torque-vectored all-wheel drive system. 

This lets it be rapid, but not scary, and despite its square and upright body, might surprise you when it comes to carving a few corners.

Like many EVs, the EQB’s weight feels low and centred, but it appears the suspension has been adjusted to remove any bouncy quality, which might come with the additional weight added over the combustion variants, with nearly 500kg of lithium batteries under the floor.

In fact, the ride is also one of the things which impressed me most about the EQB. It even has huge 20-inch AMG wheels, yet it dealt with bumps of all shapes and sizes in an impressive manner, keeping the body under control, and communicating remarkably little in terms of vibration or unpleasantness into the cabin.

The steering offes a nice balance of feel and electrical assistance, a trait which combines with the EQB’s convenient size to make for an easy SUV to park and manoeuvre.

When it comes to the EQB’s traits as an electric car, there are several modes available to alter the experience. 

Using the paddle shifters, there are several regenerative braking settings to choose from. While none of them are a ‘single pedal’ mode, the D- mode is pretty strong, and clearly contributed to the EQB’s surprisingly good energy consumption in my time with the car.

Activating D+ mode, which can be combined with a sporty driving setting, tones down the regenerative setting almost completely and feels as though it unleashes more potential from the potent electric motors. 

While the sportier settings made the 2WD EQA I tested last year feel a little twitchy and prone to wheelspin, the all-wheel drive system keeps this well under control in the larger EQB for impressive acceleration characteristics.

The breadth of this SUV’s ability is perhaps its most impressive attribute. It can feel comfortable and tame around town, with alarming speed and tenacity when attacking the open road should you so desire. 

Sure, it’s not as whiplash-inducing as some of its rivals, particularly the Volvo XC40 Recharge or Tesla Model Y, but for a luxury SUV like this it’s more than what you could ask for. 

The EQB scores a thorough suite of active safety equipment including freeway-speed auto emergency braking (7.0-200km/h), lane keep assist with lane departure warning, blind-spot monitoring with rear cross-traffic alert, as well as one of the best adaptive cruise systems on the market.

In the event of an impact, the EQB scores dual front, side, and head curtain airbags (the side and curtain bags cover both rows) as well as a driver’s knee airbag. There are the usual dual outboard ISOFIX child seat mounting points on the rear row, as well as three top-tether points.

The EQB scored a maximum five-star ANCAP safety rating to the current 2022 standards, but this rating only covers the base 250 variant. It scored highly across all criteria.

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.

Mercedes offers a five year and unlimited kilometre warranty, with five years of roadside assist. The high-voltage battery components are also covered by a separate and industry-standard eight-year and 160,000km warranty.

Service intervals are once every 12 months or 25,000km and the service plan costs an average of $440 a year for the life of the warranty which is expensive for an EV, especially considering Polestar offers free servicing for the first five years, and Volvo’s electric offerings are around half the cost over the same period.
