Kia Stonic vs MG ZST

What's the difference?

Unlike a lot of rivals in this segment, the Stonic's actually quite a bit of fun to drive, and that alone earns it a tick from me.

Yes, it can feel underpowered in places, especially when you're trying to do high-speed overtakes or if you're on a really engaging road and on and off the accelerator. But just cruising around, the little powertrain gives you plenty to get around the city.

And I guess that is the point. This does feel like a very city-friendly vehicle, even if it is undeniably showing its age in places.

Will the MG ZST Essence fit a small family? Absolutely, and all but the middle seat passenger will be comfortable but there are areas open for improvement. Like it's safety, laggy tech and adding a few extra items in the back seat.

Yet, it still offers a good host of features and an attractive package for a reasonable price tag. Unfortunately, my son missed having the basic amenities but did like the sun roof.

I'm not gonna spend too much time on the exterior design, because from most angles it largely looks a lot like a Kia Stonic, right? The big exterior change occurred up front, where the old Kia 'face' was retired, and replaced with an LED-trimmed front-end more in keeping with modern Kia models.

It is a tale of good and bad in the cabin of the Stonic. The good is the fact that it all feels very familiar and very Kia, which isn't a bad thing.

Th bad is some of the door materials aren't just cheap and hard plastic, but they feel a bit flimsy in places as well. Same with the centre console plastics. There are some elements where you could definitely lift up the ambience in the interior.

Being the newer and shinier version of the ZS, the ZST presents as a nice little package with its full suite of LED exterior lights, shiny chrome accents and its well-shaped body.

The front is distinctively different from its design muse with a darkened grille, and redesigned fog lights that feature new air intake vents. Other highlights include the 17-inch two-tone alloy wheels with sporty red brake calipers lurking behind them.

The interior is pleasant with a massive sunroof creating a light-filled space and giving the illusion that the cabin is larger than it is.

The synthetic leather upholstery and trims seem robust and perfect for families, but also feel quite plasticky under hand. The red badge embossing on the headrests is lovely, though.

The dashboard is well-proportioned and headlined by an upgraded 10.1-inch touchscreen multimedia system and fully digital instrument cluster.

The gearshift feels a tad too skinny and tall for the general aesthetic but the circular air-vents add some cute personality.

In the GT-Line trim, you get the twin screen setup, which looks sharp, and I do like Kia's multi-function control bar, which takes care of things like navigation and media on the one digital screen.

It really is feeling a little bit old school in places. There's no wireless phone mirroring, for example, so you need to plug in. And even then you need to plug in with a USB-A rather than a USB-C, despite having both plugs at your disposal.

The other thing is that the GT-Line is almost $36k before on-road costs. And there are places where it just doesn't feel like that much money.

It's a case of what you see is what you get in the back seat of the Stonic. And what you see is... not that much.

There are two USB-C ports in the more expensive trims. There are bottle holders in each of the doors, but no cup holders, and no pull-down seat divider. It is a fairly sparse back seat experience.

What you do get, however, is the luxury of space. Sitting behind my own 175cm driving position, I had absolutely no problem with knee room and no problem with head room. In fact, even as an almost full-size adult, I reckon I could sit back there pretty comfortably, even on longer road trips.

The big news is the addition of a 48-volt mild hybrid system, and that 48-volt battery is under the boot floor. But because it's hidden under a flat partition, it actually doesn't impact boot space.

Kia is still claiming 352 litres with the rear seats in place and 1155 litres with the rear seats folded flat. You do, however, miss out on some under-boot storage. And there's no spare wheel to speak of, just a tyre repair kit.

Practicality is hurt by a lack of individual storage options and a back seat that has only two USB-A ports for its amenities.

The cabin space is spacious, though, and both rows have a decent amount of leg- and headroom despite the massive sunroof.

The steering wheel features height but not reach adjustment and to accommodate I have to sit much closer to the wheel than normal thanks to my poor little T-Rex arms.

Individual storage is the best up front with a small middle console and glove box, two cupholders and two drink bottle holders. The doors also feature large storage bins, which is great to keep the cockpit feeling neat.

The rear row gets two map pockets and a small storage bin in each door. There is also a (very) shallow storage nook at the back of the middle console… think a packet of gum or small wallet size.

My seven-year old isn't as comfortable in the rear because it lacks directional air vents, reading lights and a fold-down armrest. All items which will hinder an adult's comfort, too.

The boot space is a good size at 359L but you can bump it to 1187L with the rear seats folded, the backrest featuring a 60/40 split.

The height of the floor is adjustable and when set in the lowest position creates a deep well to tuck larger items, like luggage, into.

The hard cargo cover can be awkward to shift around or store but is otherwise out of the way when it counts.

Other amenities accentuate the premium-feeling the Essence is going for with the heated front seats and electric drivers seat offering well-padded comfort but on longer journeys, I miss having adjustable lumbar support.

The rear seats aren't as comfortable as the front only because the synthetic leather feels slippery, which is accentuated when you hit corners!

In terms of technology, you get two USB-A ports in each row but the front also gets a 12-volt port. You miss out on fast and wireless charging options.

The multimedia system looks great but can be sluggish to respond and the apps can be slow to load but I like the built-in satellite navigation.

The upgraded sound system has six speakers instead of four but the sound quality is a bit tinny with music and calls.

It was simple to connect to the wired Apple CarPlay. It also has Android Auto, Bluetooth connectivity and AM/FM radio.

There are four variants for the ZST and our test vehicle is the top-spec Essence model, priced at $33,990 drive-away.

Our example's 'Pebble Black' finish is an included colour but other paintwork options can cost an extra $700.

The price point positions it right in the middle of its rivals with the Omoda 5 costing $35,990 drive-away  and the Jolion sliding into the most affordable spot at $30,990 drive-away.

To highlight the value-for-money comparison, the Kia Seltos Sport+ FWD model costs $38,790 drive-away and then you start creeping up into the $40K bracket for similarly specified small SUVs.

The ZST Essence is the top-grade and it has a decent number of premium features for its price tag, like a panoramic sunroof, synthetic leather upholstery, heated front seats and an electric driver's seat, keyless entry, keyless start and a full suite of exterior LED lights.

Other standard features include wired Apple CarPlay and Android Auto, 10.1-inch touchscreen multimedia system, digital instrument cluster, one-zone air-conditioning, built-in satellite navigation, 360-degree camera system and an upgraded sound system with six speakers.

All Stonics get the same powertrain. A clever three-cylinder, 1.0-litre turbocharged petrol engine with 48-volt mild hybrid assistance. That means 88kW and 172Nm (up from 74kW). It has a seven-speed dual-clutch transmission.

We don’t have an official zero-to-100km/h time, but I’m estimating in excess of 10 seconds.

The Essence variant has a 1.3-litre, three-cylinder turbo-petrol engine with a maximum power output of 115kW and 230Nm of torque.

It's a front-wheel drive and features a six-speed auto transmission. Overall, it has enough power to keep up with traffic on the open road but you have to be firm with the accelerator to keep your speed consistent.

The 48-volt system helps drop both fuel use and C02 emissions, with the Stonic pegged at 5.0L/100kms on the combined cycle and 116g/km for emissions, both of which are lower numbers than the last model.

The Stonic’s 45-litre tank could theoretically deliver a circa-900km driving range.

The official combined cycle fuel figure is 7.3L/100km and my real-world average came in at 7.7L. That is after a good mix of urban and open-road driving, so the usage is good.

Based on the combined fuel cycle and the relatively small 45L fuel tank, expect a driving range of around 616km.

It is a really interesting drive proposition, this Stonic.

First and foremost, it does feel really well sorted in places. The steering has a nice weight to it. It's nice and direct. The ride is comfortable. It can get a little bit crashy over the harsher bumps, which actually isn't all that common in Kia products – like if you hit a cat's eye at speed, for example, you can definitely feel it in the cabin – but generally it's an engaged and comfortable drive.

Similarly, going around corners, even at speed, there's not a huge amount of body roll. The tires grip up pretty well, and it's really not a bad thing to throw around corners.

Where it gets interesting, though, is in its power delivery. At city speeds, so 50 or 60km/h, it's nice and easy and quiet. If you're gentle with the accelerator, and patient, it accrues speed in quite a calm, considered manner, without feeling overly sluggish.

Where it does start to fall apart a little bit, which is when you're at speed, say on a freeway for example, and you pull out to overtake and really plant your foot, and find there's really not a lot there. It can mean overtaking takes a lot longer than you might think. 

If you're on a really challenging road and you're kind of on the gas, on the brakes, on the gas and on the brakes, it can feel a little bit wheezy and uncertain, too, which is no doubt a byproduct of that relatively tiny powertrain.

We're definitely not talking rocket ship acceleration, and nor is it all that quiet in the cabin when you really start to wring its neck, which you will do occasionally.

But I think I've really stepped away from what this vehicle is supposed to be and what it's supposed to do. If you are easy with the accelerator, it can be a really calm, quiet cabin experience. And if you do find yourself on a twisting road, it actually sits and grips better than you might be thinking as well.

But there is no doubt the Stonic shines brightest in the city.

The ZST Essence has an okay amount of power relative to the car's small size.

It's an adequate cruiser when I ferry just my husband and son around, but feels a full load of luggage and people.

The steering is responsive and it's an easy car to manoeuvre in tight car parks or city streets, which is great. The visibility is pretty good despite the chunkier pillars and you feel confident when checking your blind-spots.

While the suspension is fairly forgiving and ride comfort is decent, you will still notice the bumps, especially when seated in the back.

The cabin suffers from some wind and road noise and at higher speeds we had to find we raise our voices a bit to be heard. Around town, you don't notice it.

This is just a personal preference but the brake and accelerator pedals are skinnier and more centrally positioned than I prefer. You get used to it, though.

The ZST is pretty easy to park and it's great that you have a 360-degree camera system but the image quality can be grainy. You get rear parking sensors, too, but miss out on ones at the front.

The ZST Essence has a good suite of safety features that now come standard like rear cross-traffic alert and blind-spot monitoring.

Other standard features include tyre pressure monitoring, LED daytime running lights, forward collision warning, lane departure alert, adaptive cruise control, seatbelt reminders, a 360-degree camera system and rear parking sensors.

The ZST only features six airbags, while many of its rivals sport seven, including the newer front centre airbag. The ZST variant scored four- from a possible five-star ANCAP safety rating in 2017 testing.

It's important to note that the tested ZS model did not have AEB or lane support systems at the time of testing, these were introduced from the 2020 model year onwards and the ZST has both.

There are ISOFIX child seat mounts on the rear outboard seats and three top tether anchor points but two child seats will fit best. There is enough room for front occupants when a 0-4 rearward facing child seat is installed.

The Stonic is covered by Kia’s seven-year unlimited-kilometre warranty, with capped-price servicing covering the warranty term.

Servicing is required every 12 months or 10,000kms, and all seven services will set you back $3780 combined.

The ZST Essence comes with a seven-year/unlimited km warranty, which is on par with coverage offered by a growing number of its rivals.

There is a seven-year or up to 70,000km servicing program for a total cost of $2339 or an average of $334 per service, which is very competitive for the class.

Servicing intervals are at every 12 months or 10,000km, whichever occurs first, but could be annoying if you travel a lot.
