Mazda CX-30 vs Kia Niro

What's the difference?

About to enter its fifth year in market the Mazda CX-30 is holding up well and this GT SP FWD grade delivers solid value relative to its key competitors, of which there are many. It’s also space-efficient, practical and performs well with top-shelf safety, decent refinement and good dynamic ability.

Alternately, it’s crying out for a hybrid powertrain to improve fuel efficiency, the interior form and function is starting to date and while it meets the market the ownership promise could be sharper. But this little SUV is still worthy of a spot on your new-car short list.

The Kia Niro S Electric is a solid little SUV that has decent space inside and some nice specs, but it's more expensive than its nearest rivals. The EV powertrain can take a little getting used to and I would have liked a smoother ride, but the 460km driving range is good.

For first-time EV owners, this wouldn’t be a bad option if you wanted to dip your toes in the water but it will suit urban dwellers and smaller families, like mine, best. This gets a 7.5/10 from me.

My son wasn’t in love with this one. Not enough buttons for him to press and he did comment on how bumpy the ride was in the back. He gives it a 6.0/10.

Mazda continues to follow a disciplined design path with everything from the MX-5 sports car to the BT-50 dual-cab ute sharing key attributes like the brand’s signature trapezoidal grille, simple flowing lines and sleek head- and tail-lights, all wrapped up with a subtle hint of chrome here and there.

Car-spotters with the GT SP on their checklist should look out for 18-inch black metallic rims as well as black exterior trim, including the mirror caps. 

Inside, the CX-30 maintains Mazda’s restrained approach with smooth surfaces integrated across the multi-layer dash and primo leather-trimmed seats.

That said, this car is starting to show its age with the multimedia screen plonked on the top of the dash (in typical Mazda fashion) and a largely conventional instrument cluster.

Yes, the main dial is configurable courtesy of a central 7.0-inch TFT screen, but next to more recent arrivals boasting sleek, often twinned, flat screen displays the CX-30 looks and feels out of touch. 

Functionally, there’s a sensible mix of digital controls and physical buttons (points for audio volume and ventilation dials!), but… the multimedia screen can only be accessed by a rotary controller in the centre console once the car is mobile (it works as a touchscreen when you’re stationary).

Some say touchscreens take your eyes off the road so the controller makes sense, but with a sequential app like Spotify it can take a lot of twirls to get to where you want to go, which upsets concentration and takes your eyes off the road, anyway. I’d prefer the relative ease of a quick press on a screen.

Aside from all that, the materials used are high quality with soft-touch surfaces across key contact points and hard plastics confined to high-wear areas. 

It’s a compact SUV with a footprint that's 4420mm long, 1825mm wide and 1570mm tall. But while small, I wouldn’t call it cute. It’s boxier than its sibling and without any of the swoopy design elements that make the EV6 look cool. 

I do like the way the two-tone body panelling, which is seen most prominently on the C-pillar, breaks up the ‘blocky-ness’ and creates areas of interest. As do the high-mounted rear LED lights. 

Speaking of lights, the base model makes do with halogen headlights, which unfortunately stand out against the LED daytime-running lights. You’ll notice the dimmer light at night, too.

The 17-inch alloy wheels are thick for better aerodynamics but the clever two-tone colouring stops them from looking unfashionable.

The interior has a lot style cred with the curvature of the door panelling blending in almost seamlessly with the dashboard.

The gently sloping panelling that houses the multimedia systems and switchable touchscreen interface for the controls creates a very pleasing cabin space.

There are some harder plastics mixed in here but enough soft touchpoints that you won’t be bothered by them. 

At just under 4.4m long, close to 1.8m wide and little over 1.5m tall (with a 2655mm wheelbase) the CX-30 is in the middle of the pack it competes with in terms of key dimensions.

And space up front is more than adequate, with an impressive feeling of roominess for a relatively small SUV.

For storage, there’s a large lidded box (which doubles as an armrest) between the front seats as well as a pair of cupholders in front of the gear-shifter with a bay for wireless device charging ahead of that.

The glove box is big, there are bins in the doors with room for decent size bottles and a drop-down tray for sunglasses sits overhead.

Move to the rear and the amount of space on offer is surprisingly generous. Sitting behind the driver’s seat, set for my 183cm position, I have plenty of head and legroom, although three full-size adults across the back seat will be an uncomfortable proposition for anything other than short trips. A trio of up to mid-teenage kids will be fine.

Adjustable air vents at the back of the front centre console are a welcome inclusion for back-seaters and storage runs to a map pocket (weirdly, on the back of the front seat only), a pair of cupholders in the fold-down centre armrest and bins in the doors with room for smaller bottles.

In-cabin power and connectivity includes two USB-C outlets and a 12-volt socket in the front centre storage box. No USBs specifically for those in the rear, which is a miss for road trips and no 12V in the boot which can be handy when camping or picnicking.  

Speaking of the boot, cargo volume with the rear seat upright is okay for the class at 317 litres, which expands to a healthy 1479L with the 60/40 split-folding backrest lowered. For comparison the Kia Seltos coughs up 433L with the rear seat upright.

The space is illuminated, there are tie-down anchors to help secure loose loads and there’s a space-saver spare sitting under the floor.

And if you’re keen on towing a tinnie or similar you’re good to go for a 1200kg braked trailer (600kg unbraked).

It’s surprisingly roomy inside and all passengers will enjoy decent leg and headroom, but taller passengers will find the backseat cosier than the front.

As such, two child seats will fit best but you do have ISOFIX child seat mounts on the outboard positions and three top-tether points, if you need them.

The synthetic leather/cloth seat trim cleans well and is nice to touch. The seats themselves, front and rear, are well-padded and super comfortable.

The backs of the front seats can double as coat hangers and have hardened kickplates, which are always practical for little feet.

The front row gets the most amenities and tech. The 8.0-inch touchscreen multimedia system has clear graphics but is different to other Kia’s I’ve sampled recently. It seems to have been simplified but you’ll get used to it quickly.

There are plenty of charging options available, too, with a USB-A and C port, plus a 12-volt socket. Not needing a cable for the wireless Apple CarPlay is a bonus, too!

The front row also has the most storage space with two retractable cupholders, dedicated phone tray, glove box, middle console and skinny drink bottle holders in each door.

Back seat passengers enjoy two USB-C ports, reading lights, drink bottle holders in each door plus an armrest with two cupholders. As well as, a standard three-pin socket in case you need to run electrical gear or charge anything up on the go.

The windows are wide and offer good visibility but I really like the 150mm ground clearance. It was super easy for my six-year old to climb in and out, plus he got a good view this week!

The boot is good for this size SUV with 475L of capacity available. It does look more like a hatchback, because while you can readjust the floor to sit lower, the back still slopes up.

However, it was fine for my weekly grocery and school run. The 'frunk' storage is small at 20L, which is just big enough for a charging cable.

You don’t get a spare wheel but you do get a puncture repair kit. And being the base model, it’s not a powered tailgate but it’s not heavy to close.

There are two variants for the Niro, our base model, the S, and the range-topper GT-Line.

Despite being the base model, the Niro S will still set you back $65,300, before on-road costs. Which makes it about $5K dearer than the equivalent Kona Electric, and $20K more expensive than the ZS EV.

There is a hybrid Niro (also available in two grades), if you’re not quite ready to commit to a full EV life. The price isn’t as eye-watering, either, being just $44,380, before on-road costs.

The Niro is well-specified, though, and the driver will enjoy an electric seat with adjustable lumbar support while the passenger side remains manual.

The regenerative braking is customisable (levels 0-3), there’s an 'iPedal' function, a dual-zone climate system, reversing camera and the backs of the front seats even double as coat hangers.

The tech is also good, with an 8.0-inch touchscreen multimedia system, 10.25-inch digital instrument panel plus wireless Apple CarPlay and wired Android Auto all coming as standard equipment. More on the tech below.

The CX-30 GT SP is powered by a 2.5-litre, naturally aspirated, four-cylinder petrol engine producing maximum power of 139kW at 6000rpm and peak torque of 252Nm at 4000rpm.

It’s a proven all-alloy unit featuring direct-injection as well as variable intake and exhaust valve timing with drive going to the front wheels via a six-speed auto transmission. 

The AWD version of the GT SP adds an electromagnetic multi-plate clutch pack (managed by a multitude of sensors) to selectively engage the rear wheels, as well. But its engine and transmission combination is identical to this FWD model’s.

The Niro is a full EV and has a front-wheel drive drivetrain with a maximum output of 150kW/255Nm. It’s not as powerful as its stablemate and only has the single-motor which is powered by a 64.8kWh lithium-ion battery but going from 0-100km/h can still be achieved in 7.8 seconds. With specs like those, this is most suited for an urban setting.

The CX-30 GT SP FWD’s official fuel consumption figure on the combined (urban/extra-urban) cycle is 6.6L/100km, the 2.5-litre atmo four-cylinder engine emitting 154g/km of C02 in the process.

It features fuel-saving stop-start and cylinder deactivation functions as standard and over a combination of city, suburban and some freeway running we saw an average of 8.4L/100km, which is average for an SUV in this class. A comparable hybrid package would easily better this result.

Based on the car’s 51-litre fuel tank theoretical range between refills is 772km, which drops to just over 600km using our real-world test consumption number. But the good news is this CX-30 runs happily on cheaper 91 RON ‘standard’ fuel.

Such is the EV life but you can’t escape the charging.

The onboard DC charger has up to 85kW of capacity and that means on a 50kW fast charger station, you can get from 10 to 80 per cent in 65 minutes.

However, if plugged into a 350kW ultra-fast charger, you’ll only save 22 minutes because it can’t accept that faster speed.

On a 7.5kW system, you’ll go from 10 to 80 per cent in approximately nine hours, 25 minutes. On an 11kW, you’ll see that figure drop to six hours, 20 minutes.

The charging port is a Type 2 (CCS Combo2) and the car comes with an emergency charging cable that can plug into a standard three-pin domestic socket, if needed.

However, it’s slow going and you’re looking at a wait time of up to 27 hours, 30 minutes to get to a full charge. All other cables cost extra.

The official kWh/100km consumption is 16.2kWh and my average on-test figure was 14.3kWh after a mix of urban and open-road driving.

However, I did see figures getting closer to 20kWh on longer trips. Still, I would consider my average to be efficient.

The Niro S has a driving range of up to 460km (WLTP).

It’s rare in 2024 to find a small SUV that doesn’t have at least one turbocharger attached to its engine, the CX-30’s 2.5-litre ‘atmo’ four being one of those increasingly scarce examples.

But Mazda’s been laser-focused on extracting maximum power and efficiency from its non-turbo petrol engines for yonks and this one stands up well.

It doesn’t have the low-down punch a turbo typically delivers but maximum pulling power arrives at a useable 4000rpm and it’s eager enough for easy city and suburban running as well as confident freeway cruising.

Although Mazda doesn’t quote an official number you can expect a sprint from 0-100km/h in around 8.5 seconds, which is quick for the class.

Worth noting engine noise and a raspy exhaust note make their presence felt under acceleration and the throttle isn’t as refined as it could be. Not a huge deal, but a slight jerkiness is evident on initial, especially moderate, acceleration.

The six-speed auto is smooth and fuss-free, the steering wheel paddle shifters on hand if you need to intervene and select a specific ratio. ‘Sport’ mode peps things up, causing the transmission to shift down earlier and up later. But it’s aggressive in that it often holds onto a gear for too long and you find yourself diving back to the default normal setting.

Tipping the scales at just under 1.5 tonnes, the CX-30 is underpinned by a MacPherson strut front, torsion beam rear suspension and ride comfort on typically pock-marked urban surfaces is average for the category. That is, a bit jittery over bumps and corrugations but there’s no bone-jarring going on here.

Steering feel and response is good and the grippy steering wheel helps with a connection to the front tyres. Speaking of which, the standard rubber is high-performance (215/55) Dunlop SP Sport Maxx 050 which is  grippy and commendably quiet. 

Push on into a corner and the CX-30 remains balanced and predictable with body roll well under control. Torque vectoring, by engine and physical braking, is also onboard to reel things in if you overstep the mark.

Braking is by discs all around, vented at the front and solid at the rear, and they wash off speed effectively with a satisfyingly progressive pedal action.

Vision is good, which combined with the CX-30’s compact dimensions and 10.6m turning circle, means parking is easy. Especially when you factor in the hi-res reversing camera and front and rear parking sensors. 

This is a pretty simple car to drive but it doesn’t feel as fun as some other EVs I’ve driven. It can even feel sluggish when you accelerate from a full stop and that makes it feel laggy in stop/start traffic.

Once you’re on your way, the acceleration is fairly responsive. You feel confident overtaking on the open road, too.

The car feels connected to the road with minimal shuddering through the steering wheel. The car responds in a timely manner when you have to make sudden moves, which I like.

Sometimes, the lane keeping aids make it feel jerky and I turned it off in some situations.

The regen braking delivers a big physical presence like the EV6 but isn’t as refined and can feel almost ‘bunny hoppy’ at times.

You can customise it up to four levels, zero being low regen and four being the iPedal. I’m not overly fond of the iPedal, so didn’t use it that much this week and kept it at level 3.

You do have to change up how you drive an EV, so this wasn’t that surprising and something I’m sure you’d get used to.

The ride comfort is pretty mixed. Around town, it’s good but there’s quite a bit of passenger movement in this. You kinda feel like you’re bobbing along sometimes, which is jolting.

You also feel the road but the seats are so comfortable, they stop it from feeling too rough. 

Surprisingly, the cabin gets very loud with wind and road noise. You can still chat but you won’t forget that it’s there, which is a shame.

I didn’t notice much difference between the drive modes, so it was kept on 'Normal', too. 

This is very easy to park! It’s a good size for even a tight car park with a 10.6m turning circle and the reversing camera is super clear, which is great. 

However, I would have liked to have seen front parking sensors, as well as the rear sensors. You can get them on the GT-line though.

The Niro EV S has a good list of safety features, with the following being standard: LED daytime running lights, lane departure alert, lane keeping aid, blind-spot monitoring, rear cross-traffic alert, a reversing camera (with dynamic guidelines), rear parking sensors, driver fatigue alert, check rear occupant alert and adaptive cruise control (with stop/go function).

It has auto emergency braking with car, pedestrian and cyclist detection as well as junction turning assist, which is operational from 5.0-85km/h. 

The Niro was recently awarded a maximum five-star ANCAP safety rating in 2022. It has eight airbags and that does include the newer front centre airbag.

There are ISOFIX child seat mounts on the rear outboard seats and three top tethers, but two seats will fit best. And while there will be room for a 0-4 rearward facing child seat, it will encroach on front passenger comfort.

Mazda covers the CX-30 with a five-year/unlimited km warranty which is the norm in the mainstream market, and it’s worth noting a growing number of competitors are now at six, seven or even 10 years, although the latter are typically conditional on authorised dealer servicing. Roadside assistance is provided for the duration of the warranty.

Service is recommended every 12 months or 15,000km and Mazda’s ‘Service Select’ program sets maintenance pricing out to seven years, the lowest over that period being $352 and the highest $626, for an annual average of $459, which is reasonable but not exceptional for the category.

For comparison, a similarly specified Toyota C-HR averages $330 per workshop visit over the same period.

The ongoing costs are great on the Niro. It comes with Kia’s ‘better-than-average-for-the-market’ seven-year/150,000km warranty, which also covers the battery.

You get a seven-year capped-price servicing plan and services average $250 per year, which is good.

Servicing intervals are more in line with a petrol car at every 12 months or 15,000km. It’s usual to see those intervals doubled on an EV but it’s still reasonable.
