Kia Stonic vs Mitsubishi ASX

What's the difference?

Once over the little thrill of driving a car we weren't supposed to get (okay, it wasn't that thrilling), a few things became clear. You can now buy a compact SUV with a good long warranty, a bit of Kia flair and a roomy cabin, at least for its size.

It drives really well even if the transmission was a bit reluctant to do what I wanted. It's easy to park and will live very happily in the city while carrying reasonable numbers of people and their things. It may not be as bang up to date as some of its competitors, and the GT-Line's value is borderline, but it delivers plenty in its small package to a rapacious SUV market.

The Mitsubishi ASX ES is a compact SUV that, surprisingly, can fit its occupants with relative comfort. The boot is a good size and you have just enough up front to satisfy a driver for everyday use.

The size makes it perfect for urban dwellers and the ongoing costs are fantastic. But by current standards its safety is lacking a fair few items for me.

The Stonic clearly looks like it is related to the Rio, but also bears a strong resemblance to the Seltos. Underneath is the very familiar small hatch Rio but Kia says every panel is different. 

The panels might be, but have a look at the rear door and the way the glass meets the C-pillar and you can tell it's a Rio. 

Which is fine, of course, because I think the Stonic looks really good in GT-Line form, with the bigger wheels, some well-judged cladding and some nice sculpting on the body. 

If you plump for the two-tone paint job (which I think looks great), you will go without the sunroof. Also the sun-safe option, but I know some are fans of a hole in the roof.

The cabin is by-the-numbers Kia, which is to say it's well laid-out and looks good, but won't be troubling a beret-sporting art critic for superlatives. 

Unlike the exterior, it's straight out of the Rio, which does have its downsides, which we'll discuss further.

I love how the ASX looks. It has a wide stance and enough squared edges to not look too cute but its compact size should appeal to urban dwellers where space is at a premium.

The two panels at the front, which sandwich the chrome grille and house quad LED lights, add a lot of personality to the ES.

As do the 18-inch alloys and the way the lights jut out at the rear. There are multiple bright paintwork colours to choose from if you want to add your own flair.

Once inside, you’re reminded that you’re in a base-type model with the analogue instrument panel, traditional gear-shifter and handbrake, but I have fallen in ‘like’ with how old-school it is.

The fabric trims feature a nice lattice-pattern and the dashboard is simple with just three climate dials to navigate.

Overall, the interior is no-nonsense but that might appeal to drivers who don’t want to be overwhelmed by their car and its tech.

For a car this size, it's reasonably roomy. I can sit behind my driving position in the rear seat and while violin playing is off the agenda, it's not claustrophobic.

Front seat passengers have plenty of storage to play with, including a split storage box underneath the console for phone and wallet-chucking. 

You also get two cupholders, even with the space-robbing conventional handbrake (I like a standard handbrake, though, so I didn't mind too much).

Each front door has a pocket for a decent-sized bottle, but not so rears. And your back seat passengers won't have an armrest or cupholders, either.

Boot space is an impressive 352 litres (VDA) with the seats up and 1155 litres with the seats down, although you don't get a flat floor with the seats folded and you do have a drop to the boot floor over the loading lip. Nothing terrifying, but the more you know...

The ASX is roomier up front than in the rear, and taller occupants will be most comfortable in the front row. There is plenty of head- and legroom, and surprisingly for this class, there’s also a good amount of elbow room!

The front seats are comfortable and well padded and adjust manually but I miss having lumbar support on longer trips.

The fabric trims look nice and it’s great that carpet mats come standard in the ES.

The back seat offers an okay amount of room for my 168cm (5'6") height but taller occupants may feel squished.

My son struggled at times to fit his large school bag through the smaller door apertures, as they are not as wide as the front. However, its 205mm ground clearance makes it an easy car to slide into most of the time.

The back seats aren't terribly comfortable because you feel like you’re perched on top as they sit straight like a church pew. Expect a few 'oomphs' from passengers when going around corners.

Individual storage options up front are good for this class with a deep middle console and glove box, two cupholders and two drink bottle holders. Plus, there is a little cubby in front of the gear shifter which is the perfect size for a phone.

In the back, there is a single map pocket and two cupholders but I would have liked to have seen at least one USB port, too.

As you might expect at this grade level, the amenities are very basic throughout the car. It takes a while for the air conditioning to hit the back row because of the one-zone climate control and lack of directional air vents back there. This is something my son reminds me of on hot days.

The technology matches the amenities with the 8.0-inch touchscreen multimedia system being super simple on graphics and options. It is responsive but basic to use.

There are two USB-A ports and a 12-volt for charging and it’s easy to connect to the wired Apple CarPlay. There is wired Android Auto for those users, too.

The instrument panel has a small digital screen that shows your trip information and average fuel usage but is otherwise analogue and easy to read. There is digital radio and Bluetooth connectivity but that’s it for the tech.

The boot is a good size at 393L and you get a temporary spare tyre underneath the floor. The load space is level and while the tailgate isn’t powered, it’s not a heavy lid to operate.

There are six models for the ASX and ours is the second-from-the-bottom ES grade, which will cost you $27,990, before on-road costs. Let’s check out some of the features you get for the price tag.

Being at the lower end of the line-up means your specifications are a bit slim in the ES but you do enjoy an 8.0-inch touchscreen multimedia system, fabric trims, wired Apple CarPlay and Android Auto, as well as full LED exterior lights.

Other items include 18-inch alloy wheels, one-zone climate control, two USB-A ports, Bluetooth connectivity, rear parking sensors, dusk sensing headlights, rain sensing windscreen wipers, carpet mats, automatic high beam function, and a digital radio.

The price point for the ES places it as one of the more affordable options compared to its similarly specified rivals with the Kia Seltos S coming in at $29,500 and the Suzuki Vitara sitting at $31,490.

However, the MG ZS has a before on-roads cost of just $22,990 and you get a fair few more features than our test model. Some extra standard specification in the ES would make it stand out against its competition. 

The GT-Line is the only one of the three in the range to score Kia's rorty 1.0-litre, three-cylinder turbo, good for 74kW and 172Nm to haul its 1200kg weight. 

A seven-speed dual-clutch transmission drives the front wheels and you'll hit 100km/h in about 10 seconds.

The ES has a 2.0-litre, four-cylinder petrol engine with a maximum power output of 110kW and 197Nm of torque. It is a front-wheel drive and has a continuously variable automatic transmission.

For manual enthusiasts, you can option a five-speed gearbox on the base GS model but I find the ES to be perfectly adequate to run about town in. And while it’s lacking a little in power, it has enough punch for open-road driving if need be.

Kia's government-mandated fuel economy testing yielded an official combined-cycle figure of 5.4L/100km. 

As I have found over the years with this engine, that's a fairly optimistic number, my week with the Stonic delivering 8.4L/100km in an almost even mix of highway and suburban running.

The Stonic has that rarest of things in a Korean car - stop-start, which helps rein in fuel usage around town. Happily, you'll be filling the 45 litre tank with standard unleaded.

The ES has an official combined cycle fuel economy figure of 7.7km/100km but my real-world usage came to 8.6L.

This is a disappointing figure considering how much open-road driving I do, so I would expect that figure to be higher in the city. Unfortunately, the ES isn’t as economical as I was hoping.

Based on a 7.7L/100km fuel cycle and the 63-litre fuel tank, expect to see a driving range of around 829km.

I must admit to being slightly puzzled by the Stonic. I've already driven the Rio GT-Line and there is one thing that is the same between the two cars and that's the seven-speed dual clutch's awkward behaviour in traffic. 

The car I had was not at all keen to respond to the movement of my right foot on the accelerator, with my wife and I developing an in-joke about having to make a verbal suggestion about which gear to choose. 

It also rolled back more than I'd like on slopes when starting from a standstill.

The other things I didn't like were the front seats. Straight out of the Rio, they are wide but not very supportive on longer trips, such as the one we took up into the Blue Mountains (a roughly 250km round trip from our home in Sydney). 

Complaints about the seats are certainly mine, but I checked in with colleague Richard Berry, who didn't have the same hesitant transmission struggle, so it could just have been a drama with the car I drove. 

The rest of the Stonic experience is really good. The 1.0-litre turbo is definitely the one to go for if you can stretch to it. The numbers don't seem big, but it's got decent punch in the gears and cheerfully climbed the Blue Mountains quietly and without hunting up and down the gears. 

Around the city it also means it's easy to thread through the traffic, with good response from low revs when the transmission is playing well.

The steering is really nice, too, with just the right weight and speed to make city-wrangling easy. The extra ride height and softer suspension also make for a very comfortable ride around town without taking away from the body control. In fact, it's quite a bit of fun.

I feel like I’ve gone back to basics with the ASX ES. I’m much more alert in it because it doesn’t have the same standard safety tech that I’m used to (more on that below) and it took me a few drives to stop throwing my keys into the cupholder because you need the key to turn on the ignition.

I've missed the good old-fashioned turning of a key. It’s a lot more satisfying than pressing a button.

Overall, the ES is an enjoyable little SUV to drive and there is enough power to allay any worries about whether it will make it up a hill.

The ES is solidly placed on the road and handles corners well but the steering is not exactly razor sharp and you have to make big adjustments. But you get used to that pretty quickly.

In terms of ride comfort, the suspension is adequate for the smooth stuff but you’ll know it if you hit a bumpy road. The cabin noise also creeps up, which is annoying on a longer trip.

It’s certainly compact with its 4365mm length and 1640mm height but that makes the ASX easy to park. The sloping bonnet and relatively flat behind also make it easy to determine where the car starts and ends.

This is very handy because the reversing camera is a bit blurry and you miss out on front parking sensors at this grade level.

The ES has a basic safety package and it’s not until you’re in the higher grades that you enjoy items like rear cross-traffic alert, lane departure alert, or lane keeping assist.

It’s also missing a big-ticket item for me and that’s autonomous emergency braking.

The following safety features come as standard at this grade level, LED daytime running lights, forward collision warning, seat belt reminders, rear parking sensors, a reversing camera, dusk-sensing headlights and cruise control.

Models made after January 2023 are currently unrated by ANCAP but the previous ASX achieved a maximum five-star assessment back in 2014.

I’m not sure how relevant that is because it's unlikely this car would fare well with its current list of items against the updated ANCAP testing criteria.

It does have seven airbags, including a driver’s knee airbag but its rivals tend to have a few more safety features that come standard. The most similar rival would be the Suzuki Vitara S model. 

If you need to fit a child seat or two (definitely not three), there are ISOFIX child seat mounts on the rear outboard seats and three top tethers across the rear row.

Kia offers a seven-year/unlimited kilometre warranty, which is only shaded by Mitsubishi's caveat-filled, 10-year/200,000km warranty. 

The Stonic demands a return to the dealer ever 12 months or 10,000km, which is kind of irritating as the non-turbo models are 12 months/15,000km. 

As ever, Kia offers a capped-price servicing regime but the numbers aren't yet available on the website (yet).

Lucky for you, we've got them. Prices bounce around a bit and are as low as $283 and as high as $704 with the first seven years/seven services costing $3299, averaging out at $471 per visit. 

Over the five years, it's $260 more than the 1.4-litre but you're servicing more often if you drive more than 10,000km per year.

The ASX comes with the ‘Diamond Advantage’ that Mitsubishi is well-known for and that means you’ll enjoy a 10-year, or up to 200,000km warranty, whichever occurs first.

What?! I know. Pretty great. In terms of duration, that’s much better than anything else on the market at the moment.

Worth noting, however, that a five-year/100,000km warranty is 'standard' and the 10-year cover only applies to cars serviced according to the factory schedule at an authorised Mitsubishi dealership.

If you do, you’ll also enjoy a 10-year or up to 150,000km capped-priced servicing plan. 

And although the services average on the more expensive side for this class at $502 each, having those extra few years is a bonus.

Servicing intervals are reasonable at every 12 months or 15,000km, whichever occurs first.
