Mazda MX-30 vs Denza B8

What's the difference?

The MX-30 is a tough one to give you a clear verdict on. In summary, though, the math just doesn’t add up. This car is way too expensive and offers next to no range for Australia’s vast intercity distances, essentially resigning buyers to a life within city limits.

On the other hand, I love the design ethos of this little SUV. It’s truly a statement, and it’s rare to find a car that is so committed to its uniqueness. It’s also easily one of the best EVs to drive right now, so those who understand its compromises will no doubt be left with smiles on their faces.

The Denza B8 is an incredibly luxurious car that has a lot going for it, including three rows of seating, a 3.5-tonne braked towing capacity and an eye-popping price tag, but it's held back by its overall heft and cumbersome ride.

If you don’t absolutely need the third row of seating, the smaller B5 is arguably the better pick and while it’s also not perfect, it’s a very compelling package and you’ll be saving thousands of dollars in the process.

The MX-30 oozes design. I would go so far as to say this car is more focused on being a design statement than it is an SUV (as evidenced by its lack of practicality…) or an EV (as evidenced by its lack of range…).

Mazda’s Kodo design language is already eye-grabbing, so it’s to the MX-30’s credit that it manages to be striking, even against other members of the Mazda family, as it strays from a well-refined formula.

The large grille has been dumped in favour of something much smaller but the 3D effect of the Kodo face still persists. The light clusters adopt their own personality - they're inspired by the Mazda3, arguably, but they stand on their own.

The side profile, squat dimensions, and contrasting panel work (in our car’s case, a matte grey against the brand’s signature ‘Soul Red’) alert you to the fact that the MX-30 is something quite different indeed. And all this is before you notice the fact that it has clamshell rear doors.

Yep, that’s right, the MX-30 reaches into the brand’s history and brings back the outward folding door design once seen on the RX-8 rotary sports coupe. Opening it up is an event, and those doors wow onlookers with their unusual unfurling. Unfortunately, it’s not as smart as it looks, but we’ll get to that in the practicality part of this review.

The inside again blends familiar Mazda themes with entirely new ones. The material design is incredible. For the first time in a long time, I felt like a kid in some kind of tactile science museum, prodding, squeezing, and scratching at this car’s many interior elements to see if they were, in fact, made of the occasionally unbelievable materials they seem to be.

It doesn’t disappoint. Yes, the door cards really have a splash of an odd grey carpet material, very Volvo, the seats are really trimmed in some sort of synthetic leather, the quality grain of which has to be felt to be understood (it's very Mercedes), and the centre console is really made of recycled cork panelling, which is very BMW.

All of this might sound a bit silly (and the cork stuff perhaps is) but along with the stepped centre console design, weird semi-digital dash cluster and familiar bits out of other Mazdas, it is difficult to not enjoy being in such a creative and unusual space.

The commitment to this funky, unusual design, has some major practicality drawbacks, which we’ll take a look at next.

There’s no way around it, the Denza B8 is a big car. It’s almost 5.2 metres long which makes it larger than a LandCruiser 300 Series and more in line with the likes of the Land Rover Defender 130.

It looks quite boxy and tough on the outside, though it doesn’t have any features that define it specifically as a Denza beyond the inconspicuous badging. There are many angles that are reminiscent of the aforementioned Defender.

The body lines look crisper than the smaller B5, as does the semi closed-off grille and LED light script that connect the big LED headlights.

Unlike the B5, the tailgate-mounted spare wheel is much more prominent in the B8 and this therefore exaggerates its heft, not in a good way.

Inside, it’s luxurious and high-end with lots of visual appeal. I particularly like the amount of soft-touch finishes around the cabin and the overall lack of glossy piano black.

While luxurious, there’s also a rugged edge to the interior. This is most present in the large grab handles which you do need to use when getting in and out.

The amount of physical buttons and switches inside is a nice touch as you don’t need to relate on the touchscreen all the time. The fact the gear shift lever rises up when you turn on the car also adds to the special, luxurious feel.

Put simply, the MX-30 is about as practical as a sports coupe, which is a feat given it has the footprint and height of an SUV.

It starts with those clamshell doors. Sure, they look amazing, but they’re annoying to open because the handle is on the inside, so you have to open the front doors before you can open the rear ones. At best this costs you time when you’re just trying to load objects, pets, or kids, at worst it makes the rear of the cabin nearly impossible to access in a tight car park.

Even in my unit parking spot, I could barely access the rear seats, making it especially annoying when I just wanted to chuck a bag in the rear footwell.

Even if you don’t have trouble getting an adult back there, space is limited. Behind my own driving position, my knees were up against the seat in front, and while I had plenty of headroom, it feels a bit claustrophobic, thanks to the tiny windows and high beltline.

I’ll hand some credit to the commitment to this car’s design, though, the odd carpet trims continue into the rear doors, and there's even a plush padded surface for your elbows on either side. Nice touch. The seats also feel unusually low and sporty for an SUV, particularly an electric one.

As if it couldn’t be more clear that this car has the intention of being some sort of sports coupe, the front seats are lovely. Comfortable, supportive, and with plenty of soft trims throughout the cabin, I felt as though I had plenty of room here. The raised console design means the multimedia functions and toggles were easy to reach and use, and while the climate functions are somewhat awkwardly placed on a touch panel, at least they were set and forget most of the time.

There’s a tactile dial for volume control, and although the multimedia interface is dial-based rather than touch, Mazda’s system is one of the easiest to use once you get used to it.

There’s a large storage area under the centre console, hosting two USB ports and a household power outlet, and atop that there’s a cork-finished tray, which flips up to reveal dual bottle holders in the centre. Behind this there’s a small armrest console box, trimmed in the same plush padding as the doors and seats. Front occupants can also make use of small pockets in the doors and a glovebox.

Unlike some electric cars, the MX-30 doesn’t score a ‘frunk’, which seems like a wasted opportunity because the engine bay is half empty. Serviceable items look incredibly easy to access because of this, with liquid tanks and coolant hoses on display, but I can’t help but feeling Mazda could have put a small storage space here with some packaging trickery. It’s equally possible that there’s a crash-safety consideration, however.

Moving to the boot, and unfortunately there’s a small-hatch-sized 311 litres on offer, because there’s also next to no underfloor space, and you’ll have to store your charging cables in there, too, further reducing the space. With the cable bags strapped in place, the boot fit our largest (124L) CarsGuide travel case with little extra room to spare. It’s weekender luggage space at best, but then I suppose you won’t be able to go away for long with the range on offer anyway…

Hopping into the B8 you need to acquaint yourself with how the flush door handles operate. Generally they pop open when you unlock the car but sometimes they can be a little delayed.

Also inside the car there are electronic door release buttons which are nowhere near as intuitive as regular door pull handles. Sure you’d likely get used to this over time but you’ll need to explain it to new passengers all the time.

The seats in Chinese cars usually look nice but aren’t that comfortable or supportive for long-distance journeys. The B8’s are the opposite, offering great support and almost limitless adjustability. Adding to this is the standard heating, ventilation and massage functions.

Ahead of the driver is a leather-wrapped steering wheel which feels nice and has plenty of physical buttons with a tactile click when pressed.

Behind this, the digital instrument cluster is clear and high-resolution and offers a number of different layouts and informative pages you can cycle through. This allows you to customise the display.

In the centre of the dashboard is the mammoth 17.3-inch touchscreen multimedia system which is the largest central screen I have seen in a car to date. It’s a big screen for a big car and Apple CarPlay satisfyingly takes up the entire screen.

Thankfully, the screen is snappy and has a native user interface that is easy to navigate around without getting lost. I particularly like the swipe-down control centre menu that allows you to change key settings without diving into sub-menus.

My only hassle with the screen is I struggle to reach the far left-hand side due to its overall size. Perhaps a trackpad would solve this.

As I noted previously, the amount of physical switchgear around the cabin makes adjusting key functions easy. Examples include physical buttons to change the drive mode, activate the surround-view camera, adjust the suspension position and switch between EV and hybrid driving.

In terms of storage up front there are two non-ventilated 50W wireless phone chargers, two cupholders with adjustable depths, a shallow storage section under the centre console, plus a fridge/hotbox under the centre armrest.

Moving to the second row and the luxury continues. The seven-seat model features a three-seat bench that three people can easily fit across as the floor is flat, whereas the six-seat model gets uber-plush captain’s chairs.

Regardless of variant, there’s plenty of room in the second row, even for adults.

Second-row amenities include a small screen on the back of the centre console box that allows you to change the climate control and change the seat heating/ventilation, among other functions.

There’s also a button that opens the fridge/coolbox so the second-row passengers can access it. This is a nifty touch though you’d want to make sure small fingers don’t get caught as the anti-pinch function isn’t the strongest.

A feature that’s unique to the six-seat version is a massaging function on the second-row captain’s chairs. This is a very cool touch that no other SUV at this price point offers.

Accessing the third row in the six-seat version is rather easy as you only need to walk down between the captain’s chairs. It’s also simple enough in the seven-seat version as long as you access it from the kerb side.

Third-row space is decent for adults, but this shouldn’t be surprising as the B8 is such a hulking vehicle. The backrests also recline allowing for extra comfort. Amenities include air vents in the headliner, USB-C ports and scattered storage. It’s enough for seats that will likely only get occasional use.

Around the back the B8 has a side-hinged tailgate which is a little problematic as you need to allow space for it to open up in parking spaces. This is hard when the car is already 5.2m long…

With all three rows upright there is 147L of boot space, which is fine, but this expands to a much more usable 920L with the third row folded.

The boot space is square and usable, though there is a large load lip which is body-coloured and would easily get scratched if you drop something on it. Not the best in a family-oriented vehicle.

Boot-related amenities include buttons to electronically fold the second and third row seats and lower the suspension to make things easier to load into the boot, a 12V socket, scattered hooks, as well as a small underfloor section to store the changing cables.

Although it stands out like a sore thumb, it’s great to have a full-size spare wheel on the back of the tailgate. This is very helpful in the unlikely and unfortunate event you get a puncture.

The 2026 Denza B8 line-up starts at $91,000, before on-road costs, for the seven-seat version, which is strategically just under the Luxury Car Tax (LCT) threshold, whereas the flagship six-seat version is $97,990, before on-road costs.

Despite nearing $100K, this notably undercuts key rivals like the Toyota LandCruiser 300 Series and Land Rover Defender by a considerable margin, especially once you take the level of standard equipment into account.

The B8’s closest rival is currently the slightly smaller GWM Tank 500 PHEV which is priced even more competitively at $77,990, drive-away.

As a base there are 20-inch alloy wheels, adaptive LED headlights, soft-close doors, a 12.3-inch digital instrument cluster, a 17.3-inch touchscreen multimedia system, 18-speaker Devialet sound system, tri-zone climate control, leather upholstery, plus heated and ventilated seats in the first and second row.

Moving up to the six-seat version brings second-row captain’s chairs with adjustable legrests and a massage function, as well as a digital rear-view mirror, head-up display and Nappa leather upholstery.

This amount of standard equipment in a car that’s under $100K is wild and should definitely be enough to put in your consideration list if you’re after a big, three-row SUV. The smaller B5 offers similar levels of specification but goes without the third row.

The MX-30 has an electric motor on the front axle with a single-speed reduction-gear transmission. It produces low-sounding figures of 107kW and 271Nm of torque, which is less than most of its rivals, although it has more power and less torque than the equivalently sized (but much cheaper) MG ZS EV.

Although these power figures don’t look as impressive as rivals, it’s worth remembering that the MX-30 has much less weight to carry around, so when it comes to driving it’s a much better story than it appears. More on that later.

The MX-30 offers three levels of regenerative braking, controlled through the wheel-mounted paddle-shifters, a necessary touch, and one that offers decent feedback on how your driving style is affecting range, via the dash and multimedia screen.

Power comes from a plug-in hybrid set-up combining dual electric motors and a 2.0-litre turbo-petrol four-cylinder engine.

Total system outputs are a meaty 425kW and 760Nm. They need to be, as the B8 has a kerb weight of 3.3 tonnes. Despite this, Denza claims it can still do the 0-100km/h sprint in just 4.8 seconds.

Power is sent to all four wheels with a rear mechanical diff lock as standard across the line-up. A front diff lock is only offered on the six-seat version.

What’s most surprising about this big beast is it offers a segment-meeting 3500kg braked towing capacity. It also has up to 700kg of payload, depending on the variant.

The MX-30 has some advantages here, in that its tiny (35.5kWh to be precise) lithium-ion battery pack means it charges up pretty quickly. The downside? It’s not as quick as it could be, and its efficiency leaves a little to be desired.

As already discussed at length, this small battery means a very short range – between 200 and 224km depending on which standard you want to go by, and the MX-30 is claimed to consume 18.5kWh of energy on the combined cycle.

This is disappointing because not only is the claim higher than rivals like the Kona electric and Nissan Leaf, but in reality, I couldn’t best it with predominantly city driving, as I have previously been able to in all its rivals. Over some 250km of testing I managed a dash-reported 18.9kWh/100km.

The MX-30 EV takes a European-standard Type 2 CCS charger, the most popular kind in Australia, and will charge up at a rate of 50kW on DC or 6.6kW on AC.

It would have been nice to see that boosted to at least 7.2kW AC to be a bit more competitive on AC charging speed. For a car that will need to be charged frequently, even a 10-minute difference in charging time is important. While 50kW DC is about right for a battery pack this size, I assume there will be cooling issues pushing that to 100kW+ as the Hyundai Kona electric and Tesla Model 3 with nearly twice the battery size are capable of.

Mazda estimates a charge time of 36 minutes on DC, three hours on a three-phase AC charger, or nine hours from a ~2.4kW wall outlet. I charged my MX-30 a single time before returning it, from about 10 – 80 per cent, with it maxing out at around 50kW. It charged in less than 40 minutes, however, as promised.

Feeding the dual electric motors is a 36.8kWh lithium iron phosphate (LFP) battery. Denza claims it allows for an electric range of 115km, according to NEDC testing.

The battery can also be used as a power source for appliances using vehicle-to-load (V2L) functionality at rates up to 6.6kW.

AC charging is offered at rates up to 11kW, whereas DC fast-charging is offered at rates up to 120kW.

Additionally, there’s a 91L fuel tank. Denza claims this allows the B8 to have a total range of 1040km (NEDC).

Fuel consumption depends on how often you charge the battery. Denza claims the B8 will use 2.0L/100km from 100 to 25 per cent battery charge and 9.9L/100km under 25 per cent battery charge, both according to NEDC testing. Regardless, this is better than all similarly sized petrol- or diesel-powered SUVs.

Usually, it’s easier here to talk about how electric cars are different from their combustion counterparts, or how they are great for an electric car. In the case of the MX-30, however, it’s just a great car to drive.

I’ll admit, I didn’t expect this little EV to match, much less exceed the driving experience of its CX-30 sibling, but it was a pleasant surprise to find out how great it was.

It turns out that having a much smaller battery, and therefore a much lower kerb weight than most EVs, means the MX-30 feels light, agile, and rapid compared to all of its rivals, which goes some way to making up for its lesser outputs.

In fact, I had no trouble with the motor at all, with the MX-30 feeling faster and more responsive than the Hyundai Kona electric or the Kia Niro EV.

Mazda’s handling prowess is also on full show here, with the smooth and accurate steering allowing me to point this little SUV with remarkable accuracy. The steering tune is lighter than the Kona electric, but a bit more significant than the Kia Niro's. It emboldens you to have a bit of fun, and again, unlike rivals, Mazda’s suspension tune has your back.

It’s sporty enough to engage you, but not so firm that it sends tremors through the cabin, an impressive feat considering it has a less complex torsion bar rear. If anyone had asked me, I would have sworn it was multi-link all-round.

The whole experience feels very similar to helming the CX-30 or Mazda3, but I’d even say the MX-30 feels better over the front end, with less rough rebound than its siblings.

It also makes a cool noise. Mazda have given the MX-30 an artificial tone, plumbed through the speakers, and unlike the science-fiction hum generated by the Hyundai group EVs, the Mazda’s is a warm drone, more reminiscent of a combustion engine.

To be clear here, the MX-30 is no Tesla Model 3. That car is seriously rapid, with mind-bending handling, although I will say there’s a certain poise and refinement to the way the Mazda drives. Even in the corners, it’s confidence inspiring, with the torque-vectoring magic built into the electric motor on full show.

Perhaps one of the reasons that this car is a tad less efficient than its rivals is its lack of weight, which would allow more energy to be fed back into the battery during regenerative braking. Or perhaps its regen braking modes are a bit too forgiving, either way it’s nice that the Mazda offers three easily controllable levels via the paddle-shifters. I even became a fan of the quaint analogue power dial, even if it does give you a bit less feedback than the sleek software suites in Hyundai Group or Tesla offerings.

The MX-30, then, hits an unexpected niche. The benefits of its smaller battery pack and a focus on handling make this car one of the best EVs to drive today, even if you’re restricted to city limits, and regular recharging.

Behind the wheel, the Denza B8 primarily acts as an electric vehicle (EV), meaning it’s largely quiet inside the cabin when driving around normally.

Once the battery charge gets down lower, the petrol engine typically switches on to top up the battery. It largely acts as a generator and a lot of the time you can’t tell whether it’s on or off.

You’ll likely only notice it if you floor the accelerator or go up a steeper hill. Even then the engine largely stays quiet and in the background.

When the battery charge gets down low enough and you gun it, the petrol engine can directly power the front wheels. This is rare, though, because the car leaves at least 25 per cent battery charge in reserve.

With 425kW and 760Nm thanks to the dual electric motors and 2.0-litre turbo-petrol engine, the B8 is far from slow. In fact, for a 3.3-tonne beast it absolutely hauls thanks to the instantaneous torque the electric motors provide.

However in the standard drive mode there is a noticeable input lag from when you push the accelerator pedal hard and when the car starts accelerating. This is reduced in the 'Sport' drive mode.

Although the B8 may produce lots of power and torque, it feels its weight. When you accelerate hard it pitches back dramatically, much like the Jeep Grand Cherokee. It’s much more pronounced than in the smaller B5, but still smile-inducing.

As standard, the B8 line-up gets an adaptive hydraulic suspension system that is claimed to be able to self-level the car. Despite this, the B8 gets a considerable amount of body roll regardless of which drive mode you select.

Many Chinese cars have floaty, comfort-oriented suspension tunes over firmer and a more dynamic-feeling ride, and the B8 is no exception. It feels like a 3300kg+ SUV.

The kicker is, like many body-on-frame vehicles, the ride gets busy on harsher roads with more frequent bumps. As a passenger you get jostled about in the cabin.

The steering tries to disguise the overall heft of this SUV but as a result it can feel overly assisted and vague at certain points. Depending on the drive it either artificially adds or reduces resistance.

Unlike the related BYD Shark 6, the B8 gets diff locks and a low-range mode which uses a clutch pack on the rear electric motor to allow for more controlled, low-speed crawling.

The adaptive hydraulic suspension allows the car to be lowered down or lifted up. In its highest mode there is a 890mm maximum wading depth.

Interestingly, compared to the smaller B5, the B8 feels more sorted off the beaten path. Its added heft helps round off bumps more easily, plus there’s added momentum behind it.

Lastly, in terms of noise, vibration and harshness (NVH), the B8 is a very quiet car to drive. As I mentioned above, the electric-first nature automatically makes this a quiet car.

Surprisingly, given the B8 is a huge 3.3-tonne box on wheels, there is very little road and wind noise. It seems Denza has put a big emphasis on sound insulation.

The Denza B8 received a maximum five-star ANCAP safety rating based on testing conducted on the related B5 in 2025.

There are 14 airbags which notably includes coverage for the third row, plus autonomous emergency braking (AEB), blind-spot monitoring, front and rear cross-traffic alert, adaptive cruise control, front and rear parking sensors and a surround-view camera.

The majority of the active safety systems do a good job, remaining in the background and only activating when absolutely necessary. However, the driver attention monitor is over zealous and struggles to detect your eyes when you’re wearing sunglasses.

Thankfully, you can turn this off using the touchscreen but it needs to be done every single time you drive the car.

The MX-30 is covered by Mazda’s industry-standard five-year and unlimited kilometre warranty, while the battery pack is covered by a separate eight-year promise, on par with its Korean rivals. Mazda includes roadside assist for the duration of the warranty.

The EV has service intervals of 12 months or 15,000km whichever occurs first, and a five-year service plan comes in at $1273.79, working out to an average of $254.76 a year. That’s getting close to Toyota levels of cheap servicing, and so it should, given electric cars (at least in theory) have much less to attend to when it comes service time.

The Denza B8 is covered by a six-year, 150,000km warranty, whereas the battery pack is covered by an eight-year, 160,000km warranty. There’s also three years of roadside assistance.

This isn’t a standout warranty in the mainstream market, though compared to premium marques it’s a notable step up.

Logbook servicing is required every 12 months or 20,000km, whichever comes first.

The first five years' of servicing totals $3762, which averages out to just over $750 per service. This is just a tad more than the smaller B5, but it’s much cheaper than premium rivals.
