Summary
Mitsubishi ASX
While the Mitsubishi ASX has long established itself as a compact SUV fan-favourite, its rivals are becoming better specified and even more affordable, like the Kia Seltos, GWM Haval Jolion and MG ZST.
There's a long-running joke that the Mitsubishi ASX is the oldest 'new car' on the market with technology that hasn't had a makeover in close to a decade.

Kia Stonic
Small SUVs have found plenty of favour in Australia and understandably so because they offer much in the way of urban-driving appeal.
And carmakers like Kia have near-perfected the art of fulfilling drivers' needs and wants and doing so with an end product that’s quite often also easy on the eyes.
But drivers – even drivers of small SUVs – like some poke in their engine. To that end, Kia has punched some turbocharged oomph into its Stonic line-up with the introduction of the 1.0-litre, three-cylinder turbo-petrol engine previously offered only in the top-spec GT-Line.

Verdict
Mitsubishi ASX6/10
The Mitsubishi ASX ES Street can more than handle being an urban dweller. The Street style pack makes this model stand out and the cabin is practical enough that it’s a good alternative for smaller families in the city. I get why the ASX is popular and I like the basic and traditional nature of this model on most fronts but not for the safety and tech. Not in this day and age against all of the well-equipped rivals it faces.
Kia Stonic6.9/10
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.
Design
Mitsubishi ASX
The ES Street doesn’t change the ASX fundamentals but it is styled differently and the Street package adds a black front spoiler and tailgate protector with red accents, black door handles, stainless steel door scuff plates, and decals across the side panels and rear.Â
The interior sees almost no changes from the ES grade but the traditional plastic gear shifter and steering wheel are swapped out for an aluminium and leather-trimmed gear shifter and leather-wrapped steering wheel, which is a nice upgrade.
The dashboard is headlined by the tried and true (and old) 8.0-inch touchscreen multimedia system but this is a vehicle that likes tradition.
You have lots of physical buttons, dials and even a handbrake. There’s no push-button starter or digital instrument panel. If you want to move or change something, it’s going to be manual adjustment. It’s basic but there is something charming about that.
Kia Stonic
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.Â
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.
Practicality
Mitsubishi ASX
The size of the cabin is the most practical aspect of it and it is spacious for the class. Both rows enjoy decent head- and legroom and it's fairly easy to get in and out of from the front row but the back row has narrow door apertures.
The cloth seat upholstery on the seats looks nice but fatigue can set in early on a long trip due to a lack of lumbar support for the front and a lack of heavy padding overall.
The individual storage up front is great for the class with a deep middle console and glove box, two big cupholders, as well as a large drink bottle holder in each door. There is also a storage tray in front of the gear shifter for smaller items like a phone or sunnies.
Storage is minimal in the rear with two cupholders in a fold-down armrest and one single map pocket... and that's it for amenities in general. There's no directional air vents or USB ports in the back.
However, there is plenty of room for two car seats, if you had a couple of kids in tow.
Technology feels and looks outdated with the only charging options being two USB-A ports and two 12-volt sockets up front. It would be nice to see faster USB-C ports and a charging pad for the price.
The 8.0-inch touchscreen multimedia system hasn’t changed. It’s simple to look at and operate. It can catch the light, which makes it hard to see at times while on the go but is otherwise responsive.
It’s easy to connect to the wired Apple CarPlay and Bluetooth but the phone call quality was hit and miss. Sometimes it sounded tinny and sometimes it crackled.
Rounding out the cabin, the boot offers good capacity for the class at 393L and you can bump it up to 1193L if you fold the rear row. The boot aperture is wide and the level loading space means it’s super easy to fit larger items in.
The rear row also has a 60/40 split and there’s a space-saver spare tyre underneath the floor. While the ES Street doesn’t get a powered tailgate, the lid isn’t heavy to operate.
Kia Stonic
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.
Price and features
Mitsubishi ASX
There are six grades for the ASX and our test model is the ES with the Street accessory pack which makes it $30,490 before on-roads costs. That’s $2500 more than the standard ES and you’re only getting styling changes on a grade that sits second from the entry-level model.
The ES Street is more affordable than the better-specced Kia Seltos Sport (FWD) which sits at $33,050 MSRP but compared to its Chinese rivals, it’s starting to feel pricey. The MG ZST Vibe is priced from $26,490 MSRP and the GWM Haval Jolion Lux from $28,790 MSRP - both of which have more features and safety equipment installed.
Standard equipment for the ES Street includes an 8.0-inch touchscreen multimedia system with wired Apple CarPlay and Android Auto, Bluetooth as well as AM/FM and digital radio.
The ES Street also features a reversing camera, LED headlights and daytime running lights, LED front fog lights, 18-inch alloy wheels, and a space-saver spare wheel. There are two USB-A ports, manual air-conditioning, and black cloth upholstery.
The Street package adds a black front spoiler and tailgate protector with red accents, black door handles, stainless steel door scuff plates, aluminium and leather-trimmed gear shifter and leather-wrapped steering wheel instead of plastic.
The ES now comes with lane departure warning.
Kia Stonic
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.
Under the bonnet
Mitsubishi ASX
The ES has a 2.0-litre four-cylinder petrol engine that produces 110kW of power and 197Nm of torque.
That's plenty enough for urban driving but don’t expect any feeling of zippiness.
The ES Street is a front-wheel drive and has a continuously variable transmission (CVT) but you can option a manual transmission on the base GS grade, if that’s your vibe.
Kia Stonic
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.Â
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.
Efficiency
Mitsubishi ASX
The official combined cycle fuel consumption figure is a low 7.6/100km and my real-world use came out at 9.1L after a fair mix of urban and open-road driving. While not super surprised with the outcome, I was hoping for better efficiency.
Based on the official combined fuel cycle and 63L fuel tank, expect a theoretical driving range of up 829km – which is great for such a small SUV.
Kia Stonic
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.Â
Fuel requirement is 91 RON 'standard' unleaded.
Driving
Mitsubishi ASX
The ES Street delivers adequate power to make it feel within the realm of fun in the city but it starts to feel lacklustre once you hit the open road. Put your foot down and the engine whines pitifully but you never worry about not getting there - it just likes to complain.
The suspension is on the right side of firm to get road feedback but not be bothered by it. You will feel bumps but not wince when you go over them.Â
However, the ASX feels very light when you have heavy winds and the car moves around a lot at higher speeds, which I found to be unnerving at times.
Surprisingly, the ASX offers a pretty refined cabin experience in terms of noise. There is a constant low hum from the engine but wind and road noise aren't too bad and you can easily chat and listen to music without feeling like your senses are battered at the end of a trip.Â
The ES Street is a fairly comfortable cruiser in tight city streets with responsive steering and a small footprint. This makes it easy to park and while the reversing camera isn’t the best quality, you know where this car starts and ends, so it’s not a big deal.
Kia Stonic
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.Â
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.Â
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).
Safety
Mitsubishi ASX
At the time of this review, the current model year Mitsubishi ASX has not been tested with ANCAP and is unrated, but all pre-2023 models achieved a five-star rating under the 2016 protocol.
The ES Street has seven airbags, including a driver’s knee airbag, but misses out on the newer front centre airbag we're seeing on newer models.
Standard safety equipment for the ASX ES Street includes forward collision warning, DRLs, hill-start assist, ABS, lane departure alert, cruise control, engine immobiliser, child-proof locking on rear doors, and a reversing camera.
Unfortunately, all of its rivals outclass the ASX on standard safety equipment and this model misses out on biggies like lane keeping aid, blind-spot monitoring and rear cross-traffic alert.
The ASX has ISOFIX child seat mounts and three top tether points but two seats will fit best.
Kia Stonic
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.
Ownership
Mitsubishi ASX
The ASX comes with a five-year/100,000km warranty, which can be extended to 10 years/200,000km, provided the vehicle is exclusively serviced by Mitsubishi dealers and on schedule. It's a warranty that is hard to beat, although MG just announced a 10-year/250,000km warranty and that's not conditional on where it is serviced.
The ASX also comes with 10 years of capped-priced servicing and the average cost is $502 per service.
Servicing intervals are reasonable at every 12 months or 15,000km, whichever occurs first.
Kia Stonic
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.
