Kia Stonic vs Mahindra XUV3XO

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.

So, what do we make of the Mahindra XUV 3X0?

After our first taster in India, we are pleased with its presentation inside and out, packaging, quality and equipment levels.

And while driving around a brand’s own proving ground cannot give a true indication of how a vehicle performs, steers, handles, rides and stops, our initial impression is that this is an easy, confident, responsive, agile and comfortable small SUV from behind the wheel. More or less.

Of course, not knowing pricing limits a definitive verdict, but the 3XO looks promising, and we’re keen to drive it on Australian roads very soon, so watch this space.

Better still, it is obvious that Mahindra is serious about cracking Australia’s small SUV market, since the 3XO ticks so many of the essential boxes.

In the face of largely cheap yet disappointing rivals out there, that’s a very good thing.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

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.

The 3XO is not quite as new as it looks.

Although only on sale in India since last year, the newcomer is actually based on the decade-old SsangYong Tivoli, which was the first model under Mahindra’s brief ownership of the Korean brand (now under KGM control since 2023).

And, if you’ve visited India lately, you might have seen a substantially modified Mahindra version of the Tivoli, badged XUV300 and sold for five years there from 2019, and the actual basis for the 3XO.

Now, Mahindra says that the latter is around 80 per cent new, with fresh sheetmetal clothing the bones of its predecessor(s). And they’re quite contemporary threads, with crisp surfacing, striking LED lighting, clean grille finishes and a pert rear-end design.

Subaru would be proud of the squared-off wheel arches, lofty 201mm ground clearance and sub-four-metre length, while the latter helps keep the small SUV inside an Indian tax bracket. Fun fact: that’s why the old Ford EcoSport, also from Chennai, needed its spare wheel mounted on the tailgate.

The 3XO's length/width/height/wheelbase of 3990mm/1821mm/1647mm/2600mm respectively, puts the 3XO on the stubbier side of the crossover brigade. Yet with more clearances than almost all alternatives. This is crying out for a rugged 4x4 ‘Outback’ treatment.

Overall, then, the smallest of Mahindras is an effectively chunky update, with a height and stance to handle the rough and tumble of urban driving.

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.

Mahindra reckons that even though the 3XO is only four metres long, it's got the space and the practicality of some 4.7m SUVs.

Which sounds dubious, but first impressions inside reveal ample room for legs, shoulders and heads, even in the sunroof-specced AX7L. Sat high, vision is impressive too, aided by an excellent driving position on nicely-shaped seats, deep glass areas and handy 360-degree camera views.

Based on the old dashboard architecture but with a completely redesigned central touchscreen and electronic instrumentation pod (and both measuring in at 10.2 inches), the effect is modern enough, with a very welcome avoidance of screen-based buttons for actual switches that are incredibly easy to navigate.

In fact, the sheer user-friendliness of the 3XO’s interior is commendable, from the world’s deepest glovebox and chilled centre bin (in the AX7L only) to the various USB ports, cupholders and storage options. The climate control effectiveness is a given if any Indian vehicle is to succeed. And the material fit and finish seemed fine. About the only dislike is the lack of steering-wheel reach adjustment, betraying the Mahindra’s real age.

Moving to the row behind, there’s sufficient space for a pair of 180cm adults, on comfy cushions. Again, vision, storage and all amenities rate highly, with face-level vents especially appreciated at this price point. The 3XO is pitched as a sensible family-car proposition in India so the back-seat area is crucial.

Behind that is the boot, which is fairly large as well, aided by a low floor and a large hatch aperture, while a space-saver spare lurks underneath, so no stupid tyre-repair kit for this sensible small SUV.

There’s also a lot of room under the bonnet…

At the time of publishing, XUV 3XO (here-on in referred to as 3XO) pricing hadn’t been confirmed. But, we’re instructed that the entry-level AX5L will start from “about $25,000”, placing it right among the sharks.

But Mahindra is out for blood, so keyless entry/start, synthetic leather trim, a 10.2-inch touchscreen and 10.2-inch driver display, wireless Apple CarPlay/Android Auto, a surround-view camera, dual-zone climate control, electric folding mirrors, roof rails and 16-inch alloys – with a spare – are included.

From “well under $30K”, the AX7L ushers in 17-sized rims, a panoramic sunroof, Harman-Kardon audio, a chilled glovebox, fog lights, front parking sensors and a shockingly powerful (pun intended) 65W USB-C port to (more than) make up for a missing wireless charger pad.

Lined up against its Chinese and South Korean rivals, the 3XO’s specification is largely on the money. Largely.

However, no DAB+ digital radio is an oversight, and although the Mahindra includes must-have advanced driver-assist safety systems (ADAS) like autonomous emergency braking (AEB) and lane-support tech, it misses out on some secondary nice-to-have alerts optionally available on some rivals – more on them in the safety section later on.

Now, if you’re thinking that the 3XO might look a bit familiar, your eyes aren’t deceiving you. And there’s a very solid reason for that.

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.

It might be tiny and a cylinder down compared to almost all of its Asian rivals, but Mahindra’s in-house 1.2-litre three-cylinder turbo-petrol engine follows European downsizing convention.

This means it relies on advanced technologies to produce comparatively healthy power and torque outputs, being 82kW at 5000rpm and 200Nm between 1500rpm and 3500rpm respectively.

Coming in at around 1400kg, the result is a power-to-weight ratio of about 59kW per tonne, which is modest against the slightly heavier Tiggo 4’s 76kW/tonne, for instance.

Driving the front wheels is a Toyota-made six-speed torque-converter automatic, so no droney CVTs or laggy dual-clutch transmissions here. But we’re disappointed the six-speed manual gearbox offered elsewhere isn’t even an option in Australia, especially after driving the Mahindra.

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 official Australian combined fuel consumption average is 6.5 litres per 100km, which translates to 137g/km of carbon dioxide emissions. With a 42L tank, should equate to about 640km per refill.

Urban and Extra Urban numbers are 7.6L/100km and 5.9L/100km respectively.  

Just keep in mind that the 3XO is recommended to drink from the 95 RON premium unleaded petrol bowser.

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).

There’s much made about how strong and rigid the 3XO’s platform is, and it’s not just for better crash protection.

Aided by a typical MacPherson-style strut front and twist-beam rear suspension set-up, Mahindra reckons it has dialled in just the right amount of dynamic finesse to make this small SUV the keen driver’s choice.

To find out if that’s the case, we spent a couple of hours behind the wheel of one at Mahindra’s vast proving ground near Chennai. A 180km/h high-speed loop. A set of chicanes. And a few rough surfaces where we could find them. Just a taster, really.

The overall impression is that nothing betrays the 3XO’s ageing platform from behind the wheel.

Torquey and smooth, the 1.2-litre three-cylinder turbo petrol engine is punchy off the line, possessing a sporty, peppy nature as well as an endearing willingness. Adding to this is the six-speed auto, as it’s also pleasingly responsive, with no lag or jolts. This is how small turbos should behave.

We managed to max it out at almost 170km/h (indicated) on the speed bowl, where it felt dead-set stable and secure. Impressive, given the 3XO’s height and ground clearance.

But the steering seems too light and a little disconnected during low-speed manoeuvres, at least for keener drivers, but once velocities climb, it seems to weigh up with sufficient heft. This is reminiscent of the way that Volkswagens used to tune its steering some 25 years ago. Maybe that’s the biggest sign of the Tivoli’s bones lurking underneath.

What this means is that the Mahindra is not the sort of SUV you buy if you absolutely relish driving, in the way the Mazda CX-3 or the very sadly-missed Ford Puma are. Hopefully, we’ll be pleasantly surprised on Australian roads.

We never got a chance to test the suspension’s ride quality, but over the couple of bumps that we did traverse, it seemed to soak them up well enough. And even though our test 3XO lacked the (optional) rear parcel shelf, road and tyre noise seemed sufficiently contained. Again, Australian roads will reveal all.

What we can say with some confidence is that the little Mahindra is a lively, user-friendly, comfort-biased and civilised small SUV. No glaring faults or anomalies appeared, just a cheerful, charming character.

For what it represents, the 3XO seems properly engineered and tuned.

Perhaps all those years ironing out the bugs in the preceding XUV300 and Tivoli are paying dividends for today’s buyers.

We weren’t expecting that.

No Australian or European NCAP crash-test rating exists for the 3XO.

But it does include AEB with cyclist/pedestrian detection, forward collision warning, lane keep assist, traffic sign recognition, lane departure warning, high beam assist and adaptive cruise control with Smart Pilot Assist, as well as six airbags.

Plus, ISOFIX fixings are fitted to the rear seats, along with a trio of child-seat anchorage points.

However, neither grade offers rear cross-traffic alert and a blind-spot monitor, meaning the XUV 3XO may struggle to achieve a five-star ANCAP crash-test rating at this time.

That said, it recently scored five stars in India’s new (but less-stringent) Bharat NCAP test, aided by extensive body strengthening and crash-force mitigation engineering development at Mahindra’s world-class research and development centres in India.

And there’s still more safety development underway, ahead of next year’s planned ANCAP test.

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.

Mahindra offers a seven-year warranty with roadside assistance, and that is excellent news for most buyers. But the 150,000km cap when most other brands have unlimited mileage might fall a bit short for some prospective buyers’ requirements.

At the time of publishing, no service scheduling and capped-price servicing pricing information was available, but expect these to be announced after early July 2025.
