Hyundai Kona vs Kia Stonic

What's the difference?

It’s easy to see why the Hyundai Kona leads the Aussie small SUV category, with this hybrid version enhancing the car’s abilities in key areas. Sharply priced and well-specified, comfortable and practical with a hugely efficient powertrain as well as refined dynamic performance. It’s a compelling package. 

Unlike a lot of rivals in this segment, the Stonic's actually quite a bit of fun to drive, and that alone earns it a tick from me.

Yes, it can feel underpowered in places, especially when you're trying to do high-speed overtakes or if you're on a really engaging road and on and off the accelerator. But just cruising around, the little powertrain gives you plenty to get around the city.

And I guess that is the point. This does feel like a very city-friendly vehicle, even if it is undeniably showing its age in places.

The Kona’s exterior mixes smooth curves across its softly rounded nose and swollen haunches with sharp lines and geometric shapes in the lower grille, wheel arches and rear bumper.

And when the current, second-generation version arrived in mid-2023 it swapped out its predecessor’s already slimline LED daytime running lights for an even thinner strip running the width of the car, in similar fashion to the Hyundai Sonata sedan and Staria people mover.

The single line light signature is repeated with the tail-lights, a brake, reversing and indicator cluster confined to the outer rear edges.

Throw in a conspicuous diagonal character line across the doors, and bright metallic accents making a visual connection between the top of the tailgate and the lower edge of the side glass and there’s a lot going on. 

Always a subjective call, but I don’t mind the Kona’s design, although our test car’s ‘Mirage Green’ paint finish leaves me (and my significant other) cold.

Inside, the colour palette is uniformly grey which contributes to a restrained, relatively low-key feel, although light trim for the headliner and pillar covers brightens the mood somewhat.

The dash treatment is cool and contemporary, comprising a wide wrap-around instrument and media screen panel next to a narrow tray on the passenger side.

Fit and finish is impressive and details like perforated centre panels on the leather-faced seats dial up the premium feel.

I'm not gonna spend too much time on the exterior design, because from most angles it largely looks a lot like a Kia Stonic, right? The big exterior change occurred up front, where the old Kia 'face' was retired, and replaced with an LED-trimmed front-end more in keeping with modern Kia models.

It is a tale of good and bad in the cabin of the Stonic. The good is the fact that it all feels very familiar and very Kia, which isn't a bad thing.

Th bad is some of the door materials aren't just cheap and hard plastic, but they feel a bit flimsy in places as well. Same with the centre console plastics. There are some elements where you could definitely lift up the ambience in the interior.

Even though the Kona measures a relatively modest 4350mm end-to-end, it offers up copious amounts of interior space. Dr Who would be proud.

Lots of breathing room up front, with the ‘shift-by-wire’ auto transmission shifter’s location on the steering column freeing up extra space in the centre console.

There’s a lidded bin between the seats (the padded top of which doubles as a centre armrest) with an open tray the size of a shoebox in front of it (which includes a pair of swivel-out bottle or cupholders) as well as a wireless phone charging bay ahead of that.

Generous bins in the doors include a recess for large bottles, plus there’s a decent glove box on the passenger side and a handy open tray above it. Plenty of room to keep the bits and pieces of everyday life under control.

Power and connectivity for the driver and passenger runs to two USB-C sockets and a (180W) 12-volt outlet.

Switching to the back is where the Tardis factor steps up a notch, the Kona offering space more in line with a next-size-up medium SUV.

Sitting behind the driver’s seat set to my 183cm position there’s loads of leg and headroom and even enough shoulder room for three adults to get to know one another on shorter journeys. A close to flat floor also helps with foot room in the centre position. Worth noting the rear seat backrests recline slightly for extra comfort options.

No door bins as such but, again, there are recesses for bottles. Netted map pockets on the front seat backs are helpful as is a fold-down centre armrest, which includes a pair of cupholders.

Individual air vents for back-seaters (in the rear of the front centre console) is always a welcome inclusion, and there’s a small oddments tray underneath them. Another pair of USB-C sockets will keep devices charged.

Boot capacity is healthy at a class-competitive 407 litres (VDA), expanding to 1241L with the 60/40 split-folding second row seat folded.

There are storage wells behind the rear wheel tubs, multiple bag hooks and four tie-down anchors to help keep loads secure.

There’s a temporary space-saver spare under the boot floor, which gets a tick over the increasingly common repair kit option and you’ll be able to tow a 1.3-tonne braked trailer (600kg unbraked).

In the GT-Line trim, you get the twin screen setup, which looks sharp, and I do like Kia's multi-function control bar, which takes care of things like navigation and media on the one digital screen.

It really is feeling a little bit old school in places. There's no wireless phone mirroring, for example, so you need to plug in. And even then you need to plug in with a USB-A rather than a USB-C, despite having both plugs at your disposal.

The other thing is that the GT-Line is almost $36k before on-road costs. And there are places where it just doesn't feel like that much money.

It's a case of what you see is what you get in the back seat of the Stonic. And what you see is... not that much.

There are two USB-C ports in the more expensive trims. There are bottle holders in each of the doors, but no cup holders, and no pull-down seat divider. It is a fairly sparse back seat experience.

What you do get, however, is the luxury of space. Sitting behind my own 175cm driving position, I had absolutely no problem with knee room and no problem with head room. In fact, even as an almost full-size adult, I reckon I could sit back there pretty comfortably, even on longer road trips.

The big news is the addition of a 48-volt mild hybrid system, and that 48-volt battery is under the boot floor. But because it's hidden under a flat partition, it actually doesn't impact boot space.

Kia is still claiming 352 litres with the rear seats in place and 1155 litres with the rear seats folded flat. You do, however, miss out on some under-boot storage. And there's no spare wheel to speak of, just a tyre repair kit.

You can have your Stonic in three flavours, the S, Sport and GT-Line, with retail pricing stepping from $28,180, to $32,290, to the range-topping $35,740 respectively.

The S is pretty basic in terms of kit, riding on 16-inch alloys, nabbing LED lights and daytime running lights, cloth seats, manual air-con and a six-speaker stereo. Tech comes via an 8.0-inch central screen with wired Apple CarPlay and Android Auto (but make sure you pack a USB-A cable to make it work, which feels very old school), as well as a 4.2-inch driver display and a smart key with push-button start.

The Sport packs in plenty more. Your alloys are now 17 inches, you get LED front fog lights, and your cloth seats now have synthetic leather trim. You also get centre console storage, single-zone climate control, a better feeling steering wheel and shifter, and rain-sensing wipers. You also get a bigger 12.0-inch central screen, extra USB-C ports and access to the Kia Connect app and over-the-air updates.

Finally, the GT-Line rides on a unique 17-inch alloy wheel design, and nabs a sunroof, heated front seats, a heated steering wheel and ambient interior lighting. It gets the full Kia twin-screen treatment, with two 12.3-inch displays handling infotainment and driving data, and you get a wireless charger.

The Kona Hybrid is powered by a naturally aspirated 1.6-litre, four-cylinder petrol engine working in concert with a single electric motor, both driving the front wheels through a six-speed dual-clutch automatic transmission.

The all-alloy engine features dual variable valve timing and direct-injection to produce 77kW at 5700rpm and 144Nm at 4000rpm, the permanent magnet synchronous motor chipping in with 32kW/170Nm for a total combined outputs of 104kW/265Nm.

That power output is in the middle of the small hybrid SUV pack and torque is at the higher end. 

Kerb weight is a fraction over 1.5 tonnes and you can expect 0-100km/h acceleration in the high 10-second range with a top speed around 170km/h.

All Stonics get the same powertrain. A clever three-cylinder, 1.0-litre turbocharged petrol engine with 48-volt mild hybrid assistance. That means 88kW and 172Nm (up from 74kW). It has a seven-speed dual-clutch transmission.

We don’t have an official zero-to-100km/h time, but I’m estimating in excess of 10 seconds.

Hyundai’s official fuel consumption figure for the Kona Hybrid Elite, on the combined (urban/extra-urban) cycle is a miserly 3.9L/100km, the 1.6L engine emitting 89g/km of CO2 in the process.

Minimum fuel requirement is 91 RON ‘standard’ unleaded and with a 38-litre tank theoretical range is around 975km.

On test, over several hundred kays taking in city, suburban and freeway running, we saw an average of around 4.4L/100km, which is impressive and a big contributor to the car’s appeal.

Using our real-world test number, the range figure comes in at a still handy 860-plus km.

The 48-volt system helps drop both fuel use and C02 emissions, with the Stonic pegged at 5.0L/100kms on the combined cycle and 116g/km for emissions, both of which are lower numbers than the last model.

The Stonic’s 45-litre tank could theoretically deliver a circa-900km driving range.

The first things that come to mind when it comes to driving the Kona Hybrid are comfort, quietness and lack of stress.

From an ergonomic point of view the dash and cabin layout make life easy. There are physical controls for key functions like heating and ventilation, as well as audio and drive modes. Not a fan of the hard driver’s door armrest, though.

The engine is quiet and the transition between combustion and electric power is seamless. It’s fun to watch the (available) graphic screen in the driver’s display illustrating where drive is coming from at any given moment. Without it you’d be hard-pressed to know.

Acceleration is more than adequate and the powertrain’s bias towards electric propulsion means take-offs are ultra-smooth. 

Suspension is by MacPherson-type struts at the front with a multi-link rear set-up and ride quality is outstanding. Despite the Kona Hybrid’s relatively large 18-inch rims, bumps and ruts don’t cause major disruption and the Kumho Ecsta PS71 tyres (215/55) are exceptionally quiet.

Steering accuracy and road feel are both good and drive mode switches between ‘Normal’, ‘Eco’ and ‘Sport’ are noticeable, the latter dialling up urgency and dynamic response.

That said, we found ourselves in Eco most of the time, without any penalty in terms of throttle response or cruising ability.

Torque vectoring helps keep everything buttoned down if you decide to press on through your favourite set of corners, the front seats remain comfy on longer drives while keeping you securely located and the ‘shift-by-wire’ electronic gearshift is slick.

Physical brakes are ventilated discs at the front with solid rotors at the rear and they operate with reassuring smoothness. An active hydraulic booster controls regenerative braking, adjustable through three levels. Warning: the most aggressive setting makes the car annoyingly ‘shunty’ at slower speeds.  

Driver-assist safety tech makes its presence felt occasionally, but never to a disturbing degree… with one exception.

Despite the ability to program a steering wheel button to short-cut directly to the appropriate screen, the need to cancel an incessant and sometimes inaccurate overspeed warning every time you start the car is a pain.

A tidy 10.6m turning circle helps in slow-speed manoeuvres as do front, side and rear parking distance warnings and a high-quality reversing camera.

The Kona Hybrid is as good or better than anything in the class when it comes to the drive experience.

It is a really interesting drive proposition, this Stonic.

First and foremost, it does feel really well sorted in places. The steering has a nice weight to it. It's nice and direct. The ride is comfortable. It can get a little bit crashy over the harsher bumps, which actually isn't all that common in Kia products – like if you hit a cat's eye at speed, for example, you can definitely feel it in the cabin – but generally it's an engaged and comfortable drive.

Similarly, going around corners, even at speed, there's not a huge amount of body roll. The tires grip up pretty well, and it's really not a bad thing to throw around corners.

Where it gets interesting, though, is in its power delivery. At city speeds, so 50 or 60km/h, it's nice and easy and quiet. If you're gentle with the accelerator, and patient, it accrues speed in quite a calm, considered manner, without feeling overly sluggish.

Where it does start to fall apart a little bit, which is when you're at speed, say on a freeway for example, and you pull out to overtake and really plant your foot, and find there's really not a lot there. It can mean overtaking takes a lot longer than you might think. 

If you're on a really challenging road and you're kind of on the gas, on the brakes, on the gas and on the brakes, it can feel a little bit wheezy and uncertain, too, which is no doubt a byproduct of that relatively tiny powertrain.

We're definitely not talking rocket ship acceleration, and nor is it all that quiet in the cabin when you really start to wring its neck, which you will do occasionally.

But I think I've really stepped away from what this vehicle is supposed to be and what it's supposed to do. If you are easy with the accelerator, it can be a really calm, quiet cabin experience. And if you do find yourself on a twisting road, it actually sits and grips better than you might be thinking as well.

But there is no doubt the Stonic shines brightest in the city.

There’s no immediate plan to crash test the new Stonic, meaning its five-star rating has now expired.

All models get things like lane keeping assist with lane follow assist, and blind spot collision avoidance and front and rear parking sensors. The S also gets auto emergency braking (AEB) with car, pedestrian and cyclist avoidance, but the Sport and GT-Line both add junction turning to the system.

The Kona is covered by Hyundai’s seven-year/unlimited-km warranty (upgraded from five years mid-last year), which is ahead of the mainstream five-year warranty pack.

Roadside assistance is complimentary for the first year, with the deal extended for another 12 months every time the car is serviced at an authorised Hyundai dealer. 

Speaking of which, scheduled servicing is recommended every 12 months/10,000km, which is a little lower than the (15,000km) norm for the category. After a complimentary check up at six weeks/1500km, the first seven services (in line with Hyundai’s ‘Lifetime Service Plan Pricing’) come in at $3782, for an average of $540 per workshop visit.

That’s on the high side considering an equivalent Toyota Corolla Cross (in line with ‘Toyota Service Advantage’ pricing) will set you back an average of $354 per service over the same period.

Hyundai has a network of 185 dealers covering every Australian capital, state and territory.

The Stonic is covered by Kia’s seven-year unlimited-kilometre warranty, with capped-price servicing covering the warranty term.

Servicing is required every 12 months or 10,000kms, and all seven services will set you back $3780 combined.
