Kia Stonic vs Kia Cerato

What's the difference?

All in all, the Stonic is a satisfactory daily driver, it’s just nowhere near ideal as a modern urban conveyance.

Sure, it’s reasonably priced in an increasingly expensive market, but it is very sluggish off the mark which is a solid negative against its overall rating. It also feels cheap inside and lacks contemporary driver-assist tech, such as adaptive cruise control.

Kia has value and packaging on its side with the sleek and spunky Cerato GT sedan. There’s no shortage of standard gear, it comes with the latest multimedia and safety gear and the cabin and cargo area are spacious and practical.

The powertrain is a winner too. Which is why it’s such a shame that it’s let down so badly by the ride quality.

If you’re going to be driving on various road surfaces, or regularly driving long distance, check out the far more compliant Hyundai i30 N-Line instead.

But if you’ll only ever drive in urban areas – or enjoy the occasional back-road blast – and you can handle the firm ride, there’s still plenty to like about the Cerato GT.

I spend the lion’s share of my time in large and upper large 4WDs, so spending quality time in something like this little hot hatchbac… er, small SUV, is a revelation and a lot of zippy fun. Like driving a go-kart without the fumes and the prangs.

The 2025 Kia Stonic Sport is 4140mm long (with a 2580mm wheelbase), 1760mm wide and 1520mm high. It has a listed kerb weight of 1227kg.

This is a slick-looking hatchbac… er, light SUV, and it looks suitably sporty. 

Though ground clearance is unlisted, it stands well clear of the road surface, giving this hatchbac… er, compact SUV, more presence than it otherwise might have.

When the fourth-gen Cerato sedan was revealed in US-market Kia Forte guise at the 2018 Detroit motor show, the design was praised for taking inspiration from the sleek Stinger performance sedan.

The facelift has arrived at just the right time to keep the Cerato fresh against the dominant Toyota Corolla, Mazda3 and new Volkswagen Golf.

The sharpened front-end styling features an eye-catching daytime running light signature and the headlights now connect with the redesigned, slimline Kia ‘tiger-nose’ grille in gloss black.

It’s a subtle, yet successful design refresh.

Inside, the Cerato is starting to look its age against rivals like the Golf and Mazda3. Those GT themed additions definitely lift the ambience of the cabin, but the dash layout feels a bit generic and the overall interior design is nothing flash. Especially when you consider the interior of some of Kia’s latest models, like the impressive Sportage medium SUV.

The Stonic Sport’s interior is a practical space but it feels a bit dated and underdone in a car market increasingly packed with well-equipped, cheaper and more contemporary SUVs.

The most obvious factors working against the Sport are its the 8.0-inch touchscreen multimedia (too small), the absence of wireless Apple CarPlay and Android Auto and wireless phone charging and multiple hard plastic surfaces.

Sure, the touchscreen is easy enough to operate, but it sometimes takes a few finger stabs to hit the sweet spot you’re after, and thankfully there are dials and buttons off-screen as alternatives for air con controls, etc.

There’s a satisfactory number of storage spaces in the front including two cupholders between the seats, a few little receptacles for your everyday carry gear, and bottle holders in each of the front doors.

The back seat is short on cupholders – there are none – but there are bottle holders in the doors, and the passengers back there get a USB-A port, a map pocket (in the back of the front passenger’s seat) and flip-down grab handles. There are no directional air vents.

Back-seat room is satisfactory for an adult without being spacious, but fine for kids. What do you expect in a small SUV?

In terms of packability, the cargo area (with the rear seat up and in use) yields a listed 352 litres of space. The rear seats are in a 60/40 split fold configuration and with them folded down there is a listed 1155 litres of useable room.

The rear cargo area has bag hooks, a storage space in the left-hand inner wall, and tie-down points at each corner of the floor.

A steel space-saver spare wheel is under the cargo area floor.

As mentioned, the red stitching throughout, chunky steering wheel and sports seats are welcome additions to the GT cabin.

There are soft-touch materials on the top of the dash but hard plastics on the dash fascia. 

There’s no fully digital instrument cluster, but it has a 4.2-inch LCD display in the cluster showing fuel economy and the like. No complaints with the analogue dials and there’s a digital speedo if required.

The update ushered in Kia’s latest multimedia system to the Cerato and it’s a winner thanks to cool graphics, logical menus and its ease of use.

There’s quite a sizable central storage bin and glovebox, while the console houses a key slot, two sizeable cupholders and a second spot for devices adjacent to the charging pad.

The front sports seats look sexy, have excellent side and body bolstering and they’re firm, but comfortable.

A 600mL bottle will just fit into the doors, bit it’s tight.

Sitting behind my six-foot (182cm) frame in the rear, legroom is adequate but toe room is tight. My head was about an inch away from the headliner due to the sloping roofline. The rear seats are also firm.

The Cerato has lower rear air vents, one USB-C port, a map pocket on the passenger side, a central rear armrest with two cupholders, and bottles slot into the doors easier than they do up front.

Kia offers a temporary spare wheel housed under the boot floor. The boot is long, offering an impressive 502 litres (VDA) of cargo space, which is more than other small sedans like the Subaru Impreza (460L VDA) and the Hyundai i30 (474L VDA).

Lower the rear 60/40 seats via the levers in the boot and that space increases further, but they don’t fold completely flat.

The GT is priced at $35,290 before on-road costs regardless of whether you opt for the four-door sedan (as tested here) or the five-door hatchback, though be aware that Kia Australia regularly runs drive-away pricing campaigns.

There’s not a lot of competition in the warmed-up small car market these days. A number of carmakers have slimmed down their small-car line-ups in the face of falling sales.

Kia’s closest rival is also its mechanical sibling, the Hyundai i30 N-Line sedan and hatch. The Hyundai is cheaper by more than $2500, but the more generously equipped i30 N-Line Premium sedan is a little over $2000 more expensive than the Cerato GT.

The Mazda3 GT sedan and hatch could also be considered a rival and pricing is about on par with the Kia.

Other lower grades in the Cerato range run from $25,490 to $30,640 (MSRP).

The GT benefits from the more premium powertrain offering in the Cerato line-up – the 1.6-litre turbocharged four-cylinder engine shared with the i30 N-Line and the recently discontinued Veloster Turbo.

The GT bodykit adds sporty styling flourishes like a black front and rear diffuser, boot spoiler, dual exhaust, black external mirror caps, red highlights and 18-inch GT alloy wheels. 

This theme carries through to the cabin too with features like alloy sports pedals, flat-bottom perforated leather sports steering wheel and leather-appointed seats with red stitching and embossed GT logo.

As the range flagship, the GT also has the most standard equipment. It comes with a sunroof, eight-way power driver’s seat, wireless device charging, an eight-speaker JBL premium sound system, heated and ventilated front seats and dual-zone climate control air conditioning.

The only option fitted to the test car was Snow White Pearl premium paint for $520.

The 2025 Kia Sonic Sport has a 1.0-litre three-cylinder turbo-petrol engine – producing 74kW at 4500-6000rpm and 172Nm at 1500-4000rpm – and that’s paired with a seven-speed dual-clutch automatic transmission. 

This pairing is a mostly punchy one, although definite lagginess is evident from a standing start often enough that it’s a disconcerting characteristic rather than a mildly annoying one.

This turbocharged engine used to only be offered in the top-spec GT-Line, so it’s a welcome addition to the other grades.

While all other Cerato grades use a 112kW/192Nm 2.0-litre naturally aspirated petrol engine, the GT benefits from a spicier powertrain.

Under the bonnet is the Hyundai Group 1.6-litre T-GDI four-cylinder turbocharged petrol engine delivering 150kW of power at 6000rpm and 265Nm of torque at 1500-4500rpm. This is the same tune as the Hyundai i30 N-Line.

This is paired with a seven-speed dual-clutch automatic transmission that drives the front wheels. Lower grades use a six-speed torque converter auto. Kia dropped the manual from the S and Sport grades as part of the update.

The GT differs from the rest of the Cerato range as it has multi-link rear suspension, instead of a torsion beam setup. Both the suspension and steering have been tuned for dynamic driving. More on that later.

Kia's official fuel consumption figure for the Stonic Sport is 5.4L/100km, on a combined (urban/extra-urban) cycle. And on this test I recorded 8.2L/100km.

The Stonic Sport has an 45-litre fuel tank so, going by my on-test fuel figure, you could reasonably expect a driving range of about 548km from a full tank. 

Fuel requirement is 91 RON 'standard' unleaded.

According to Kia, the Cerato GT sedan uses 6.9 litres of fuel per 100km on the combined cycle. The GT hatch uses 0.1L less.

After a week of mixed driving in the Cerato GT, we recorded a combined fuel consumption figure of 9.0L/100km – a fair bit more than Kia’s claim.

The GT emits 157g/km of CO2 (official combined).

The Stonic Sport is a handy urban conveyance, but it is far from perfect.

It’s a small, light vehicle so it’s nimble for navigating through car-packed streets and convenient for tricky parking manoeuvres.

Steering is well weighted and precise.

And the turbocharged petrol engine is a welcome addition to the Stonic package, introducing a handy amount of power and torque which is sensibly harnessed and delivered – most of the time anyway – via the mostly clever transmission.

However, in stop-start, inner-city traffic or even a busy suburban area, the Stonic Sport struggles to get off the mark from a standstill, so much so that this one characteristic threatens to spoil the rest of the driving experience. 

Once the Sport is out on the open road, it’s a pleasant cruiser as this compact SUV simply rolls along.

Ride is firm – 17-inch wheels and low-profile tyres are the culprits here – and handling is impressive.

In terms of refinement the Stonic is mostly, um, fine but there is some tyre noise, especially over rougher roads out of the city, but it’s not terrible.

Every Stonic has three drive modes – 'Normal', 'Sport' and 'Eco' – each of which tweaks throttle response, engine output and transmission settings to best suit the driver and conditions. 

The Stonic is generally a reasonable daily driver, but the absence of adaptive cruise control is a let-down when it comes to highway running.

Not that you’ll be buying a Stonic with the aim of skull-dragging a 3500kg caravan along the highway, but it’s handy to know this Kia SUV’s towing capacities are 450kg (unbraked trailer) and 900kg (braked).

The 1.6-litre turbo engine is a ripper and it’s been put to good use in Hyundai’s i30 N-Line and Veloster Turbo.

It’s just as willing and responsive under the bonnet of the Cerato GT, but they each perform quite differently.

Accelerating from a standing start, there’s mild turbo lag in the Cerato, and some torque steer when accelerating hard.

Once up and running it’s quick, and the seven-speed dual clutch snaps through the gears smoothly while still allowing it to rev freely.

It’s the type of powertrain that is utterly unbothered by things like steep ascents. The Cerato GT just keeps pushing on, without losing momentum.

The downside of that is that the engine is super noisy when pushed and the Kia just doesn’t have sufficient noise suppression materials to counter that. Because of this, it lacks the refinement of its i30 N-Line cousin and the Mazda3.

Steering is weighted on the heavier side but it’s direct and the car goes where you point it.

Like many Kia models, the Cerato GT benefits from an Australian-specific steering and suspension tune. Kia doesn’t have a full performance hot hatch to line up with the i30 N, but the engineers seem to have tuned the suspension to be just as capable as the full-fat i30 N.

That certainly aids dynamic driving in the Cerato GT. It hugs corners and grips the road, avoiding any skipping and with only a hint of body roll.

However, we think Kia’s engineers have made the damper settings too firm, because the Cerato GT’s ride is harsh in virtually all driving environments.

A new, freshly laid road surface in an urban area without any speed bumps was the only time the ride was comfortable during our week with the car.

It crashes over potholes and it’s loud and jarring when you unexpectedly encounter a sharp rut. There’s a bit of vibration through the steering wheel too.

This is disappointing, especially when you consider that the i30 N-Line has a much more supple ride and is the sort of warmed-up hatch or sedan you could easily live with day to day.

We briefly drove the i30 N hot hatch just before we got into the Cerato GT and even that has a more tolerable ride quality than the Kia.

The Cerato GT achieved a five-star ANCAP crash safety rating in 2019 and it applies to all Cerato variants built after June 2021, except the S and Sport which have four stars because the autonomous emergency braking system offered as standard in those grades can’t detect vulnerable road users like pedestrians and cyclists.

Standard safety for the GT includes auto emergency braking (AEB) with pedestrian and cyclist detection, forward collision warning, rear occupant alert, driver attention assist, rear cross-traffic alert with collision avoidance, blind spot detection and collision avoidance assist, adaptive cruise control, lane keep assist with lane follow assist steering, safe exit warning, front and rear parking sensors and a reversing camera.

At one point, the AEB kicked in pulling out of a parallel street parking spot because it detected a vehicle that had already driven past the car and was several metres ahead.

Kia’s lane keep assist system is generally impressive and functions without issue, but it pulls on the wheel a little. It’s not jolty like systems offered by some other brands.

When lane keep and follow assist are active, it can be fiddly to switch them both off. If you hold the steering wheel-mounted button down, the follow assist stays on but the lane keeping deactivates, so you just have to keep holding the button down until the lane and steering wheel icons in the digital display eventually disappear.

Kia’s seven-year/unlimited kilometre warranty applies to the Stonic and you have access to roadside assistance for up to eight years as long as you always get it serviced at an authorised Kia garage.

Servicing intervals are set at every 12 months or 10,000km, whichever comes soonest.

Service costs start at $290 (12 months/10,000km), peak at $727 (48 months/40,000km) and finish at $578 (84 months/70,000km) and the total over seven years is $3367; an average of $481 per workshop visit (correct at time of writing). That’s rather pricey for something in the small SUV market.

The Cerato, like all Kia models, is offered with a seven-year/unlimited kilometre warranty, and one-year free roadside assist which extends year by year if you service with Kia (up to eight years).

It also comes with a seven-year capped-price servicing plan that costs approximately $3234 over the seven-year period.

Servicing intervals for the Cerato GT are every year or 10,000km, whichever comes first.
