Mazda CX-3 vs Mazda MX-30

What's the difference?

It’s easy to see why the Mazda CX-3 remains such a favourite with small SUV buyers. The Evolve grade tested is dynamically capable, space efficient and well equipped for the money. That said, although I don’t like being ageist, as it starts to creep up on a decade on sale, the market leader is giving ground to the competition in key areas including design, fuel efficiency and refinement. It’s time for a new-generation model, but in the age of electrification, will there be one? In the meantime, this evergreen favourite remains a solid urban SUV option.

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.

You’re not going to mistake the current CX-3 for anything other than a Mazda, which speaks to the consistency of the brand’s design approach.

Tightly wrapped and neatly detailed the CX-3's exterior has aged well, and thanks to cosmetic tweaks over time it’s still looking clean and contemporary. 

The step up from 16-inch alloys on the lower Sport and Pure grades to 18-inch rims on this Evolve also lifts the look to a more mature, premium level.  

The interior is a simple, fuss-free environment, but in a small-SUV world moving rapidly towards slick integrated screens for multimedia and instrumentation, the CX-3 is showing its age.

The 8.0-inch media display stands proud in the centre of the dash, almost like an afterthought, and the instrument cluster, while okay from an ergonomic point of view, is dated by an analogue tachometer in the centre and LCD-style read-outs either side.

And although it’s always a subjective call, I’m guessing the Evolve’s white and tan interior trim combination won’t be to everyone’s liking, from an aesthetic or practicality point-of-view.

That said, the interior surfaces across the dash, doors and centre console flow into one another nicely, and brushed metal look highlights around key controls and vents enhance the quality feel.

Speaking of which, physical dials and knobs for adjustment of the ventilation system and audio volume is welcome. Maybe old-school is the best school?

However… the multimedia screen can only be accessed by a rotary dial in the front centre console once the car is mobile (it works as a touchscreen when you’re stationary).

Keenly aware there are various opinions on this set-up when it comes to safety. Touchscreens, by definition, take your eyes off the road ahead, so on one hand it makes sense to transfer control to the rotary dial.

But when you’re using a sequential app like Spotify, it can take a hell of a lot of twirls of that controller to get to where you want to go.

Soon you’re grinding your teeth in frustration which upsets concentration and your eyes are well-and-truly off the road, anyway. 

For what it’s worth, I’d prefer the relative ease of a quick press on the screen rather than having to go ‘around the horn’ to hit your favourite track or podcast.

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.

At just under 4.3m long, less than 1.8m wide and a little over 1.5m tall the CX-3’s footprint is squarely city-sized, and no surprise it shares the Mazda2’s 2570mm wheelbase because it’s underpinned by the same platform as the small hatch.

But there’s more than enough breathing room up front and storage options are creative.

Rather than the ubiquitous single storage box between the front seats the CX-3 offers up an adjustable multi-compartment arrangement, with cupholders and bottle retainers ready to flick into position in multiple locations. 

It’s still covered with a padded lid which doubles as an armrest, and there’s also a generous glove box and bins in the doors with space for large bottles, even an overhead drop-down glasses holder.

Move to the back and there’s a surprising amount of head, leg and shoulder room for an SUV of this size. Sure, it’s no limo, but sitting behind the driver’s seat set to my 183cm position, I was pretty comfortable.

Best for two full-size adults in the rear, although a third can squeeze in for short, relatively uncomfortable journeys. Three up to mid-teenage kids will be fine.  

Rear storage includes bottle shaped cavities in the doors, a map pocket on the back of the front passenger seat only (a weird Mazda habit) and dual pop-out cupholders in the fold-down centre armrest.

No adjustable ventilation outlets in the rear, but in a car this compact, their absence isn’t as big an issue as it might be elsewhere.

For power and connectivity, there are two USB-A sockets in the front (one media, one power-only) as well an SD card slot, an ‘aux in’ jack and a 12V outlet. No power options in the rear, which won’t play well with the kids.

With the back seat upright, boot capacity is an okay 264 litres. Enough to accommodate either the largest 124L or the smaller 95L and 36L suitcases from out three-piece set. But not all of them together.

With a bit of not so gentle persuasion, the large CarsGuide pram just squeaked in, but lower the 60/40 split-folding rear backrest and available space expands to 1174L.

Tie-down anchors to help secure loose loads is a plus and a speed-limited space-saver spare sits under the boot floor.

And if you need to hook up a small boat or other lightweight trailer, the CX-3 Evolve is rated to 1200kg (braked) and 640kg (unbraked).

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…

The price and features equation for electric cars is somewhat different from the status quo of their combustion equivalents. You can’t just consider standard spec inclusions, there’s a need to factor in range and charging capability, too, as battery capacity and AC to DC charging converters can have a dramatic effect on the cost.

Frustratingly for Mazda’s EV offering, the sums don’t add up as neatly as I’d like them to. The MX-30 EV is available in one top-spec trim, the E35 Astina, which wears a before-on-roads cost (MSRP) of $65,490.

This places it in the same league as the Hyundai Kona electric Highlander ($66,000), Kia Niro EV S ($67,490), and Tesla Model 3 Standard Range + which just had a significant price cut ($59,900).

To make things worse for our fledging Mazda EV, it has a WLTP-rated range of just 200km (or 225km using the ADR method)! There’s no two ways about it; this is pitiful in the face of the aforementioned rivals, all of which offer ranges in excess of 420km when measured against the same standard. Even the much cheaper base-model Nissan Leaf ($49,990) offers 270km of range.

You can’t not factor this in with an EV purchase, particularly in Australia where grand distances between cities essentially rules out any intercity trips for the MX-30 EV.

The brand is hoping this car’s funky and innovative design cues, which we’ll talk about in the next part of this review, will win the hearts of city-slickers, but the MX-30 is not lacking on the standard equipment front, either.

Stuff you’ll get out of the box includes 18-inch alloy wheels, an 8.8-inch multimedia screen (which, like this car’s CX-30 and Mazda3 siblings is a non-touch unit, controlled through a central dial), Apple CarPlay and Android Auto connectivity, a 7.0-inch semi-digital dash cluster, Bose 12-speaker premium audio, built-in sat-nav, head-up display, semi leather synthetic interior trim, full LED exterior lighting, a holographic head-up display, single-zone climate control with its own 7.0-inch touch panel controller, heated front seats, as well as keyless entry with push-start ignition.

The MX-30 has some unique interior materials, and I’m not sure why more EVs don’t have a full-size domestic power socket, as this car does under the centre console at the front. Handy for when you need to charge household devices larger than a phone on-the-go (hair-curling tongs perhaps?). There are a few spec omissions, however. Dual-zone climate, power seat adjust, and a wireless phone charger are chief among the missing.

The CX-3 is powered by a 2.0-litre, four-cylinder petrol engine sending drive to the front wheels via a six-speed auto transmission.

The all-alloy unit features direct-injection and variable valve timing to produce 110kW at 6000rpm and 195Nm at 2800rpm.

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.

Mazda’s official fuel economy number for the combined (ADR 81/02 - urban, extra-urban) cycle is 6.3L/100km, the 2.0-litre four-cylinder emitting 143g/km of CO2 in the process.

That’s an impressively small emissions figure for a 2.0L petrol engine, more in line with smaller-capacity engines.

Stop-start is standard and over a week of city, suburban, and some freeway running, we averaged 7.4L/100km (at the pump), while the car’s on-board computer indicated 7.1L/100km for the same period.

Minimum fuel requirement is 91 RON ‘standard’ unleaded (or E10) and you’ll need 48 litres of it to fill the tank.

Using the official number, that translates to a driving range of around 760km, which drops to roughly 650km using our real-world figure.

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.

The CX-3’s compact size makes it easy to steer through tight city and suburban streets. 

It weighs in at just under 1.3 tonnes, which is marginally lighter than most of its key competitors, and acceleration is sprightly with the 0-100km/h covered in less than nine seconds.

Close to 200Nm of pulling power is plenty for a car in this class and unusually for a non-turbo engine, peak torque arrives at a relatively low 2800rpm, so there’s ample mid-range urge.

The downside is the 2.0-litre, four-cylinder engine makes its presence felt inside the cabin, with mechanical noise noticeable even at around-town speeds. Not a conversation stopper by any means, but it’s there.

No complaints with the six-speed auto transmission. It’s smooth and the ratios keep the car in its performance sweet spot nicely. It also shifts into sequential ‘Manual’ mode if your prefer or need to call the shots.

Electric ‘drive-by-wire’ throttle response is smooth, but flick the console-mounted rocker switch to ‘Sport’ and things become more urgent, with the transmission shifting down earlier and holding on to ratios longer.

The steering is evenly weighted for easy parking and road feel is good. Speaking of parking, a 10.6m turning circle is large-ish for such a diminutive SUV, but surprisingly, not out of line for the category.

Suspension is by struts at the front and torsion beam at the rear, and despite the CX-3’s relatively short wheelbase and the Evolve’s bigger 18-inch wheels, ride comfort over typically pock-marked urban roads is surprisingly good. The Toyo Proxes R52A (215/50) tyres are also quiet and reassuringly grippy.

Braking is by generous ventilated discs at the front and solid rotors at the rear, and they’re more than up to the task of calmly washing off speed in this city-sized SUV. 

The front seats proved comfy and supportive on test, although you’ll have to step up to the next Touring grade to score electric adjustment for the drive or lumbar control of any description.

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.

Like all recently launched Mazdas, the MX-30 is packed full of advanced ‘i-Activesense’ safety gear. In terms of cutting-edge items, this includes freeway-speed auto emergency braking, now with low-speed intersection assist as well as pedestrian and cyclist detection, lane-keep assist with lane-departure warning, blind-spot monitoring with active intervention, as well as front and rear cross traffic alert, with rear emergency braking.

The MX-30 also has the expected suite of electronic assistance but goes further to include torque vectoring and has a total of 10 airbags – a lot for a very small cabin. It also comes packed standard with front and rear parking sensors, as well as a 360-degree parking camera suite. It’s amongst the best safety suites in terms of pure features in the small SUV segment.

The MX-30 has a maximum five-star ANCAP safety rating to the 2020 standards.

Mazda covers the CX-3 with a five-year/unlimited-kilometre warranty, which is the current market standard. Roadside assist is included for the duration. 

Recommended service interval is 12 months/15,000km, and the average annual cost for each workshop visit, for the first seven years, is $438.

An average under $450 is alright, but Toyota’s capped price figure of $195 per workshop visit for the first five years of C-HR ownership puts it in perspective. Mind you, Toyota’s charges step up considerably after that fifth year.

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.
