Nissan X-TRAIL vs Kia Stonic

What's the difference?

Over four generations Nissan has fine-tuned the X-Trail into an impressively refined and practical option for an urban family; that practicality further extended by inclusion of two occasional seats in the third row of this N-Trek version. The value equation is also strong and safety is top-shelf.

That said, efficiency is far from class-leading and the ownership proposition is off the category pace. But this even-seater’s overall quality still shines through. 

If you’re in the midst of the mid-size SUV market vortex and want seven seats rather than five make sure this car’s on your investigation list.

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.

Busy but interesting is a description you might apply to a mad rocket scientist or rock ‘n’ roll roadie. But it’s also apt when looking at the Nissan X-Trail’s exterior design.

Long, angular head and front fog lights sitting either side of a large grille and above multiple air intakes set the tone at the front with a similar mix of accentuated tail-lights and jagged shapes at the rear.

There’s enough distinctive character there to identify the X-Trail as a contemporary Nissan and I for one like the look of it, especially in our test example’s ‘Ceramic Grey’ finish.

For car-spotters, the N-Trek is distinguished by specific 18-inch (mainly black) alloys, a unique front and rear bumper treatment and a blacked-out grille as well as a black finish on the door handles, mirror covers and roof rails.

This third-generation X-Trail arrived less than two years ago and the interior remains classy and restrained, Nissan so far resisting the temptation to join media and instrument displays into the increasingly common single array.

The sweeping multi-level dash is fuss-free and the muted, mainly grey and black colour palette is calming yet bright enough to avoid crossing the line into sombre.  

Its layout is simple and ergonomically efficient with details like manual dials for audio and heating/ventilation control a plus.

And it’s the things you don’t regularly notice that are worth calling out. The electric handbrake is near silent on application; not always the case in recently released rivals. The rear windscreen wiper motor is also quiet; again, something you can’t take for granted these days. And the quality of the materials across the interior is a cut above those most often used by ‘challenger’ brands.

I could go on, but you get the idea. Lots of small ‘one per cent’ things that may seem minor on their own but add up to make a noticeable difference overall.

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.

At just under 4.7m long, a fraction over 1.8m wide and a bit more than 1.7m tall, the current Nissan X-Trail is a large mid-size SUV.

That allows for a generous amount of space up front with more than enough breathing room between the driver and co-pilot.

Storage is pretty handy, too, with a decent size lidded ‘butterfly door’ box between the seats (which doubles as a centre armrest), two cupholders in the centre console, a lower level tray underneath, door bins with space for large bottles and a decent glove box.

Move to the second row and at 183cm tall I have plenty of headroom and legroom, with the latter variable thanks to the seat’s ability to slide and open up more room for the two third-row occupants if required.

Again, there are bins in the doors with a cavity able to accommodate large-ish bottles, two cupholders in the fold-down centre armrest and map pockets on the front seat backs, while adjustable ventilation gets a big thumbs up.

Three full-size adults across the second-row seat is a recipe for discomfort but two grown-ups or a trio of up to mid-teenage kids will be fine and the rear doors deserve a big shout out. 

First, they open out to 90 degrees which makes getting in and out of there s-o-o much easier and second, pull-up sunshades are always a welcome addition.

The third row is a kids-only zone, but the flexibility those two spots offer is significant and Nissan’s provision of big outer armrests with storage and drink holders built in is a thoughtful touch.

Connectivity and power options run to USB-A and -C ports (for streaming and charging) plus a 12-volt socket and wireless device charging pad in the front. There’s an identical pair of (charge only) USBs in the centre row and another 12-volt outlet in the boot. 

Speaking of which, with all seats up the seven-seat X-Trail’s boot capacity shrinks to that of an oversize handbag (realistically, two or three soft bags), but with the 50/50 split third row folded down you’re provided with 465 litres of volume (to the roof) which is enough to easily swallow the three-piece CarsGuide suitcase set. And the 40/20/40 split second row’s sliding ability again allows you to play with the space available.

Worth noting a space-saver spare is provided (a much better option than a ‘roll of the dice’ repair/inflator kit) and maximum braked trailer towing capacity is a handy 2000kg (750kg unbraked).

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.

The Kia Stonic is available in three grades – the S ($25,460), our test vehicle, the mid-spec Sport ($28,590) and the GT-Line ($31,780), all prices excluding on-road costs. All have five seats.

Standard features include an 8.0-inch touchscreen multimedia system (with wired Apple CarPlay and Android Auto), satellite navigation, digital radio, two USB charging ports, single-zone climate control, six-way manual driver’s seat adjustment, a premium shift knob, premium steering wheel, and Tricot cloth trim seats.

It also has 17-inch alloy wheels, push-button start and rear privacy glass.

Standard paint is 'Clear White', but premium options including 'Sparkling Silver', 'Astro Grey', 'Aurora Black Pearl', 'Signal Red', 'Sporty Blue', 'Honeybee' and 'Snow White Pearl' cost $520.

The X-Trail N-Trek is powered by a 2.5-litre, naturally aspirated, four-cylinder petrol engine developing 135kW at 6000rpm and 244Nm at 3600rpm. Not a turbo in sight, which is increasingly rare as emissions standards for internal-combustion engine cars continue to tighten.

That said, the X-Trail’s hugely popular corporate sibling, the Mitsubishi Outlander (they share the same chassis platform) has the identical engine residing under its bonnet.

The all-alloy unit features direct-injection and electronically-controlled variable valve timing to produce outputs in the same ballpark as other category favourites like the Kia Sportage 1.6 turbo (132kW/265Nm) and Mazda CX-5 2.5 (140kW/252Nm). But the Toyota RAV4 Hybrid AWD steps ahead on power at 163kW.

Power is transferred to all four wheels via a CVT auto with a ‘Drive and Terrain Mode Selector’ offering ‘Auto’, ‘Eco’, ‘Sport’, ‘Snow’ and ‘Off-Road’ modes.

The AWD system is on-demand with steering angle, yaw rate and G-force sensors feeding into an electronically controlled coupling ahead of the rear differential able to adjust torque distribution between the front and rear axles from 100:0 to 50:50 on the fly.

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.

Nissan’s official combined cycle fuel-economy figure for the X-Trail N-Trek is 7.8L/100km, the 2.5-litre four emitting 183g/km of CO2 in the process.

That number’s in line with other non-hybrid competitors but some way off the Toyota RAV4’s 4.8L/100km.

Over a week covering mainly urban and suburban driving as well as some freeway running we recorded an average of 9.9L/100km, measured at the pump, while the on-board computer coughed up a more optimistic 9.1L/100km.

That’s starting to get up there for the class although the result’s balanced somewhat by the X-Trail’s ability to run happily on 91 RON ‘standard’ unleaded.

You’ll need 55 litres of it to fill the tank which translates to a theoretical range of around 700km and roughly 550km using our real-world number.

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.

The best way to describe driving the X-Trail N-Trek is stress-free. It’s quiet, comfortable and composed with enough oomph for the cut and thrust of urban driving as well as the occasional foray onto the highway.

Maximum pulling power arrives at 3600rpm, which is higher than the small-capacity turbo SUVs the X-Trail most often competes with. But the pay off is crisp throttle response and you’re never found wanting for performance.

Drive goes to all four wheels via a ’shift-by-wire’ continuously variable transmission (CVT). By design CVTs cause the engine to hunt up and down the rev range, searching for the optimal gearing compromise between power and efficiency. But the CVT ’droning’ syndrome that characteristic can generate isn’t a noticeable factor in the X-Trail.

The strut front, multi-link rear suspension delivers smooth ride comfort helped in no small part by the standard 235/60x18 Bridgestone Potenza Sport A/S tyre’s cushy 60-series sidewall profile.

That rubber plays a part in the car’s modest road noise with wind noise on the freeway also low for a relatively upright SUV. The X-Trail also steers nicely with well-weighted assistance and good road feel.

We didn’t head off-road for this family review but the N-Trek’s variable AWD capability gives it the ability to confidently deal with loose or slippery unsealed surfaces.

An 11.1m turning circle is nice and tight, which, in concert with a reversing camera, 360-degree camera view and front and rear proximity sensors makes parking a straight-forward exercise.

Brakes are discs all around (ventilated at the front) and the pedal is agreeably progressive.

In fact, that kind of refinement is a hallmark of the way this car operates. Recently arrived competitors can be noticeably abrupt when it comes to brake, throttle and steering inputs.

Not so here. As mentioned in the Design section, these one per cent positive qualities lift the X-Trail above the norm.

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 Kia Stonic has the maximum five-star ANCAP safety rating as a result of testing in 2017, but that rating is set to expire in 2025.

Standard safety features include six airbags (dual front, front side and full-length curtain), as well as a suite of driver-assist tech, including AEB (with forward collision warning, car, pedestrian and cyclist detection), lane-keep assist, front and rear parking sensors and blind-spot collision avoidance. But it doesn’t have adaptive cruise control which is disappointing in this day and age.

Nissan covers the X-Trail with a five-year, unlimited-kilometre warranty, which is the norm in the mainstream market. That said, the likes of GWM, Kia and MG are at seven years, unlimited-km with Mitsubishi offering conditional 10-year, 200,000km cover. Roadside Assist is included for five years.

The main service interval is 12 months/10,000km which is behind the more common 12 months/15,000km period, although pre-paid maintenance is available offering an approximate 10 per cent saving over (still capped-price) pay-as-you-go.

Pre-payment also means you can fold the cost of maintenance into the financing of the car (if you’re going that way).

For the X-Trail AWD, pre-paid servicing comes in at $2092 for five services within five years ($418.40 per workshop visit) compared to $2324 for individual capped-price services ($464.80 per visit). 

There’s that 10 per cent saving but it’s still relatively pricey when you consider the Toyota RAV4 Hybrid costs $260 per service.

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.
