Kia Stonic vs Tesla Model Y

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.

Tesla promised wholesale improvements to the Model Y, and this Juniper update delivers where it counts. But with increased, and sometimes cheaper, competition arriving every day, the pressure remains on Tesla to keep the Model Y ahead of the pack.

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.

We’re not talking massive changes here – more a modernising of the Model Y offering that doesn’t really change the shape or dimensions. 

The most noticeable changes outside are the front and rear light bars, spanning the width of both the bonnet and the boot. They’re a nice touch, and seriously soften what many (including me) consider the worst angles of the Model Y. There are also new headlights, a refreshed front bumper and a new look for the alloy wheels.

Inside, it is the absolute definition of pared-back minimalism. In fact, some could argue it’s gone a little bit too far.

There are no physical buttons anywhere but on the steering wheel, and there's just the one stalk, which has the sole function of operating the indicators. Everything else - mirrors, windscreen wipers, headlights etc - are accessed either through the steering wheel, or through the central screen.

And that includes the gear selector, which is now a swipe-down-for-reverse, swipe-up-for-drive function on the central screen. You might love that, but I don't. I'm sure I'd get more used to it, but initially it did nothing but slow down how quickly I could get the car moving.

Helpfully, the central screen is big and very easy use, and logging into Spotify and Apple CarPlay does largely negate the missing phone mirroring – though if the function exists, I couldn't get it to read my incoming texts to me.

Our test car's cabin was black but highlighted with quality-feeling fabric panels in the doors and on the dash, which are then framed by a metallic-feeling mesh, helping the Model Y's cabin feel definitely elevated from the vehicles that came before it.

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 new Model Y stretches 4792mm long, 1982mm wide and 1624mm tall, and the practicality perks of the outgoing model still shine strongly in this new version.

Climb into the backseat and you’ll find a seriously spacious area, and one that feels even bigger and lighter thanks to the completely flat floor and the glass roof.

Even sitting behind my own 175cm driving position, there was ample knee and headroom, and the addition of the 8.0-inch rear screen, which supports two headphone connections, is a clever touch. Gone are the mind-numbing days of staring out the window on long family road trips. Now, kids get access to YouTube, Netflix and a heap of games.

There are also two USB charge points, and a pull-down divider that separates the comfortable rear seats. The door pockets front and rear are sizeable, and cabin storage abounds, including a hugely deep storage bin that separates the front seats.

Open the boot, and remove the shade, and you'll find another fairly massive storage area, including a deep hidden area under the boot floor. But you won't find a spare tyre – instead Tesla offers a 24-hour call-out service for the life of the warranty, where someone will come and repair or replace your tyre, should you have an issue.

Tesla isn't good at detailing specifics about its vehicles, but says you can expect a total 2138 litres of storage space in the Model Y, presumably with the rear seats folded flat and measured to the ceiling.

So yes, this Model Y RWD is the cheapest way into the Model Y family, listing at $58,900 before on-road costs – exactly $10k cheaper than the Long Range All-Wheel Drive.

That’s a little more than some of its core Chinese rivals, like the XPeng G6 which kicks off at $54,800, and a lot more than vehicles like the Leapmotor C10 and Geely EX5. But you could argue that Tesla has more brand standing than them in Australia, given it has been around for so much longer. 

Tesla has also jacked up the included features for this update, with heating and cooling for the front seats, new 19-inch alloy wheel designs, adaptive LED headlights, and a very cool 8.0-inch rear screen that gives backseat riders access to games, YouTube and Netflix.

Tech up front is handled by a 15.4-inch central screen on which you can connect your Spotify or Apple accounts, but there’s no Apple CarPlay and Android Auto. The system pairs with a nine-speaker stereo, and there’s still the best wireless charging pad in the business below the screen.

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.

Again, Tesla keeps its cards close to its chest on specific outputs, but data we've seen points to this Tesla's rear-mounted electric motor producing 255kW, a smallish increase from the 220kW of the outgoing model.

Tesla says that's enough to produce a sprint to 100km/h time of 5.9 seconds.

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.

Again, more cloak and dagger from Tesla here, but most reporting suggests a 75kWh battery is housed beneath the new Model Y.

We do know that our rear-drive Model Y will deliver a claimed 466km driving range on the WLTP cycle.

Charging is capped at a reported 220kW, with the brand suggesting 238km in driving range can be added in 15 minutes when using a 175kW Supercharger. Home AC charging is capped at 11kW.

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).

Reviewing a Tesla Model Y at the moment is no mean feat. The company's very public figurehead is fighting for a front-row grid position in the battle for world's most unlikeable human at the moment.

But anyway, journalist hat on, personal views aside, Tesla has done a good job with the new Model Y. I actually didn't much like the outgoing model – the ride was too harsh, the steering too darty and the cabin too austere – but Tesla has comprehensively overhauled each of those drawbacks to create a car that is genuinely much better than it has ever been before.

Let's start with the cabin. It's still austere, but the quality feels higher and more premium, and while I'll die on a hill of the screen-controlled drive selector being a bad idea, it is otherwise now a nice place to spend time. The screen and the software powering it largely replace the perks of Apple CarPlay, and the addition of the rear screen is a very good one, too.

But the biggest improvements are in the way the Model Y drives. It's far more compliant on Sydney roads, while the steering sensitivity has been dialled back so it doesn't feel as though you're constantly making corrections.

I also like the power delivery in the RWD. It's not lightning fast, but the grunt is constant and feels really instantaneous and usable.

It's no sports car, though. Our test car took in some of the windiest roads in greater Sydney and beyond, and while the body roll and composure feels on point, the Model Y does struggle with really sharp cornering. The aggressive traction control was a constant passenger on the really challenging stuff.

Overall, the improvements are good, and very noticeable.

This Tesla Model Y wears the same five-star ANCAP safety rating as its predecessor, awarded back in 2022.

Everything you expect is present and accounted for, including seven airbags, auto emergency braking (AEB), lane departure warning and assist (the latter being a little too panicky for my tastes) and cameras front and rear.

Special mention for the brand's semi-autonomous functionality, which – while not perfect – is among the best I've experienced. On the highway, it will stay in the centre of its lane, rather than the bumper-bowling-style swaying that some systems serve up, and change lanes for you when you indicate.

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.

Underwhelming, I'm afraid. A four-year/80,000km warranty might be the worst offered by any mainstream brand in the country. For the record, five-year/unlimited km is now the minimum standard, with many brands far exceeding that.

Servicing intervals are a bit scattered, with the brand instead listing when things need to be done, rather than a traditional schedule.
