Mazda 3 vs Kia Niro

What's the difference?

Given how effortlessly it traverses the mainstream and premium small car classes, the Mazda 3 might be the best value small car on the planet.

With racy styling, sports car handling, classy interior presentation and impressive, intelligent efficiency, there’s plenty to sink your teeth into here.

Poor rear vision, a dark back-seat area and smallish boot aside, it doesn’t have any glaring faults.

In a world overrun with SUVs, props to Mazda for evolving the small car so brilliantly to mask a half-decade of existence. Continuous improvements have made the 2024 G25 Evolve SP Vision an essential small car shortlist proposition, regardless of price.

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.

How is it that the current Mazda 3 is already five years old? This hatchback is still stunning, the sort of car you look back at when walking away.

The shape is sleek and almost coupe-like, with a shark-like nose, cab-backward-style long bonnet, upswept shoulder line and a fastback silhouette.

More importantly, it’s the way the light dances across the sculptured sides that draw the eyes in. Bereft of clutter, it makes you wish all mainstream manufacturers had the courage to be so daring.

We’ve said it before – the 'BP'-generation Mazda 3 (Axela in Japan) is the brand’s boldest C-segment hatch since the 1993 'BA' 323 (Astina/Lantis/323F).

But there’s a price to pay for such timeless beauty…

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. 

There is a price to pay for all this quasi-coupe styling flair, and that’s a comparatively snug-feeling interior, though you’d never call it cramped.

Actually, the Mazda 3 is no less spacious than most of its competition in all but one area, with enough room even for 200cm drivers, along with sufficient shoulder width and ceiling height to match.

If you’re really tall, maybe that missing sunroof isn’t such a bad thing, after all.

Sat so low-down on cushy, enveloping front seats that offer plenty of comfort and support, this is the anti-SUV. Maybe Mazda should have called this the MX-3.

Sporty and spot-on, the driving position is a laid-back affair, with an emphasis on better ergonomics, as emphasised by the thoughtful placement of switchgear that’s all within easy reach, ahead of a beautifully flowing and layered dash. Proudly Japanese in flavour, it brings to mind functional minimalism.

Drilling into some of the 3’s finer interior details, the analogue-look digital instrumentation is super-legible, ultra-classy and gorgeously lit at night. As previously mentioned, the dials and surrounding air vents are reminiscent of the later Porsche 944 and 968.

It’s not just all for the sake of aesthetics, either.

Yes, it’s lovely, but the thinned-rim three-spoke steering wheel feels great to grip, with nifty little paddle shifters that are a delight to prod.

Same goes for the physical volume knob and climate-control buttons, sidestepping the need to get distracted and frustrated by virtual sub-menus.

And having a conventional gear lever with old-school Tiptronic-style shifts suits the 3’s athletic vibe.

Plus, forward vision is A-OK, ventilation is faultless, storage is better than you might expect, and the fit and finish is as good if not better than any of this 3’s German premium opponents.

Out back, the split-fold rear backrest is set at a comfortable angle, the cushion is well padded, and you’re provided with USB ports, air vents, and an armrest with two cupholders. More thoughtfulness.

But while knee room is fair, rear headroom isn’t great if you’re tall or wear a beehive, as the falling ceiling line reveals.

Vision out is limited by that rising window line and fat pillars. Getting in and out of the back requires some contortionist moves. And the small windows mean it can be gloomier in the back than a Smiths album.

Finally, at just 295 litres, the 3’s cargo capacity is disappointing. Sure, it eclipses the Corolla hatch’s 217L cubby, but other rivals are far larger back there.

At least the floor is wide and flat and there are 60/40-split backrests for cabin access for longer items.

Note that a space-saver spare wheel lurks underneath. Mazda argues there’s always the closely-related CX-30 if you need (slightly) more space (317L).

Meanwhile, at the other end of the 3…

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.

When you think about it, shoehorning a big torquey engine in a light and agile small car is a recipe for fun. Ford did just that with the Escort RS2000 in the 1970s… and Mazda’s now an expert at it, too.

The engine in question is the G25, a 2.5-litre four-cylinder naturally aspirated twin-cam petrol engine, delivering 139kW of power at 6000rpm and 252Nm of torque at 4000rpm.

As this Evolve SP Vision hatch tips the scales at 1415kg, it makes for a healthy, and consequently very lively, power-to-weight ratio of over 98kW/tonne.

That’s if you decide to use all the available revs, which the six-speed torque-converter auto makes great use of.

Driving the front wheels, it offers a 'Sport' mode to extend the revs even more, which is keeping in line with this Mazda’s sporty character.

Less so is the company’s decision to ditch the old multi-link independent rear suspension system a few years back for a more prosaic torsion beam arrangement. We’ll get to how that affects ride and handling in a moment.

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.

Mazda claims the G25 averages 6.6L/100km on the combined cycle… for a carbon-dioxide emissions rating of 154g/km. On a 51L tank, that gives a potential distance of over 940km!

Driven good and hard in our hands, we managed 7.5L/100km, which isn’t bad given the speed and conditions it was subjected to.

Plus, the Mazda’s happy on 91 RON 'standard' unleaded petrol.

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).

Ask yourself. What do you want from a new small car?

Since the first Familia of the early 1960s, Mazda’s been at it constantly, through the 1300 and 323 eras and into the modern age of the 3.

The Hiroshima brand knows its stuff. Space, practicality, comfort, ease, reliability and affordability. But a small car has to offer more, specifically in the way it makes the owner feel.

That’s why, while the Focuses, Lancers, Astras and Pulsars are gone, the 3’s still here. And it isn’t just the lush visuals inside and out that are, well, sensory-rich.

As older Alfa Romeo owners know, there’s something special about an engine that sounds alive, and the moment you push the 3’s starter, it purrs into life. That’s the first clue.

Slot the refreshingly old-school lever into Drive, and the G25 leaps into action, and, if you need it to, will keep pulling forward strongly, engine buzzing, like it’s on a mission.

That describes the torquey urge of this big 2.5L four, paired perfectly with the sensibly-geared auto.

We miss Mazda’s magnificent manual immensely, but the 3’s instant response reflects its favourable circa-100kW/tonne power-to-weight ratio.

And, as we’ve harped on in the past, the twin-cam unit’s extra oomph beyond 4000rpm delivers muscular high-speed responses akin to a good turbo – or a great old-school Alfa. You can keep your laggy dual-clutch transmissions, Europe.

Now, sweet, smooth and speedy performance is one thing, but having the chassis tuned with precise and fluid steering for tactile handling, and confident roadholding, backed by nuanced driver-assist and traction controls, are another.

There is a consistent and unifying control to the 3’s linear and forgiving dynamics, reminiscent of past masters like the Focus (and today’s brilliant Peugeot 308) that makes it a joy to drive enthusiastically through fast corners, with the knowledge that it won’t suddenly snap-oversteer and bite an unalert driver back.

For a Mazda, the ride is quiet enough, but there is still some droning transmitted through the cabin, via the Bridgestone Turanza (215/45) tyres, on coarse-chip bitumen surfaces.

And while suspension comfort is pretty impressive for the most part, larger bumps reveal the torsion beam’s limitations, as the car can occasionally thud over them in a way that we remember the multi-link rear end wouldn’t.

Anyway, what we’re saying is that, overall, the 3 Evolve SP Vision is an immersive and interactive driving experience that is right up there with the best of them.

Brawny performance, exquisite agility and a refinement that, collectively, have eluded every small Mazda in living memory until this generation’s 2019 debut. This 3’s right on the money. Still.

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 offers a five-year/unlimited kilometre warranty, with five-years roadside assistance… and that’s nothing special nowadays.

Service intervals are at 12 months or every 15,000km.

A fixed-price service scheme is available, averaging out to $434 annually over the first five years. Mazda shows pricing right up to 16 years and 240,000km on its website.

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.
