Kia Stonic vs MG MG4

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.

The MG4 was a game changing electric car, resetting the price benchmark while also being a very good small car in its own right. But as we discovered when we tested the rest of the range, the MG4 is a car that gets more compelling the cheaper it is. The $38,990 MG4 Excite 51 is arguably the pick of the range given its value equation.

But that’s not to say the MG4 XPower isn’t a good car. It’s a very quick car that will play the role of daily driver and weekend fun machine well. Just not quite as well as its petrol-powered rivals.

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.

What really stands out about the design is… that not much stands out about the design. At least in differentiating the XPower from the rest of the MG4 line-up.

There are no pumped out wheel arches or a bigger, sportier spoiler that makes it look different in the same way a GR Corolla won’t be mistaken for a regular Corolla hatch.

Instead, the XPower has the same 'Energetic Agile' silhouette and includes the same ‘Active Intake spoiler’ at the front and the ‘Twin-Aero’ rear spoiler that’s the same as the Essence models.

There are some differences though, including more pronounced styling on the sides of the doors. It doesn’t add any performance benefit but creates a slight visual difference between the models in the range.

Surprisingly, there is very little to signify that this is the sportiest XPower model, with a distinct lack of badging - inside and out. In fact, the only visual clue that this is the XPower is on the bright orange brake calipers. Or, to be more accurate, brake caliper covers.

These are just lightweight metal covers that make the MG4 braking hardware look bigger than it really is, so it’s a bit of visual trickery from the MG designers.

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.

As with the exterior, there’s not a lot to differentiate the XPower from the rest of the line-up. No bright red Civic Type R style interior treatment here. MG has opted to carry over the minimalist design that no doubt contributes to the sharp pricing.

Probably the only notable difference is the seat trim, with the XPower model getting a combination of synthetic leather and suede for a sportier look and feel. But the rest is largely the same, which detracts slightly from its hot hatch credentials.

On the plus side, the MG4 cabin is generally a well-designed interior space, which is a positive for the XPower’s hot hatch argument, as the idea behind the ‘hot hatch’ is that it can be a practical car during the week and fun on the weekends. 

There’s good room for passengers and luggage, in large part thanks to the relatively slim battery design that frees up more cabin space. Front seat occupants will enjoy the space and good visibility on offer.

Small item storage is very good in the MG4, with a pair of cupholders, a large, flat lidded tray (with one USB-C and one USB-A outlet just above) and the centre console box all fitting between the front seats.

There’s also a wireless smartphone charging pad that sits halfway up the centre fascia, next to the rotary gear selector, but it’s a shallow space so your phone will almost certainly fly out as soon as you begin cornering vigorously.

However, once again highlighting the ways MG has saved money to keep costs down, the back seat accommodation isn’t anywhere near as well appointed.

While the space is adequate for a small hatch, there are no cupholders, no air-conditioning vents and no fold down armrest for those in the back. All they have access to are some pockets on the back of the front seats, including a pair of small ones high on the seat, seemingly designed to accommodate your smartphone.

In another positive for its hot hatch practicality, there are ISOFIX points on the outer rear seats, neatly covered by leather pieces for a cleaner look when you don’t have kids.

As for the boot, the XPower measures the same 363 litres with the seats up which is unchanged from the rest of the MG4 line-up.

Disappointingly, there’s no obvious place to stow the charging cable, even though it comes in a small, neat bag. This is a worryingly common trend with these early generation EVs that shows a lack of practical thinking from the designers.

The MG4 has no under-bonnet storage either, so it feels like a few wasted opportunities for what is a bespoke EV design.

While we’ll dive into performance and the headline figures of the XPower soon, there’s another number that’s arguably more impressive - the price.

The MG4 XPower is priced from $59,990 (plus on-road costs), making it only $4000 more expensive than the range-topping MG4 Essence 77.

More importantly, when compared to the likes of the $72,600 Honda Civic Type R, $68,990 Volkswagen Golf R, $64,190 Toyota GR Corolla and $57,990 Subaru WRX tS Sport the XPower is arguably one of the first EVs to achieve true price parity with its internal combustion engine rivals (although the Cupra Born starts at $59,990 so it can argue the same).

Beyond the performance upgrades we’ll detail below, that price brings a well-equipped car.

The XPower comes with 18-inch alloy wheels, LED headlights and tail-lights as well as vehicle-to-load (V2L) functionality.

It also comes with a six-speaker sound system, Bluetooth, navigation, Apple CarPlay and Android Auto, a wireless smartphone charging pad and synthetic leather and Alcantara trim. 

There’s the 'MG Pilot' safety package included as standard as well, but we’ll detail that below.

The 'Hunter Green' hero paint colour is exclusive to the XPower in the MG4 range, and is reportedly inspired by an MG land speed record car the legendary Sir Stirling Moss drove in the 1950s.

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.

This is arguably the biggest single difference between the XPower and the rest of the MG4 line-up. Unlike the others that have a single, rear-mounted electric motor, the XPower adds a second motor on the front axle.

This has an obvious impact on the performance, boosting it from the previous best of 180kW to an impressive 320kW/600Nm.

Having motors on each axle also means the XPower is all-wheel drive, so it has little trouble transferring all that grunt to the road.

So much so that the MG4 XPower is the equal quickest hot hatch on the market (at the time of publication), taking just 3.8 seconds to run 0-100km/h; matching the Audi RS3, with its turbocharged five-cylinder engine.

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.

Interestingly, the XPower is not fitted with the biggest battery in the MG4 range, forgoing the 77kWh version in favour of the 64kWh option.

In the ‘standard’ rear-wheel drive MG4 Excite 64 model this battery can provide up to 450km of range (on the WLTP cycle) but in the XPower that figure is reduced to 400km.

While that’s well short of the 530km offered by the long-range Essence 77 model, it’s still a respectable amount of driving range and should suit your typical hot hatch buyer, who knows performance typically comes at the expense of efficiency.

Our test drive was limited to just two days, so we didn't have the chance to live with the XPower for an extended period, but it managed to make it this reviewer’s preferred hot hatch playground on the edge of the city and back again to home with more than 50 per cent of the battery charge remaining.

This was a trip that included a lot of urban driving, some highway and then some ‘spirited’ running on the twisty road, so there’s enough range from the XPower to meet most buyers' needs.

Across almost seven hours of driving, the MG’s trip computer was claiming an average energy use of 18.6kWh/100km. To replenish the batteries, a 140kW DC charger will take just 30 minutes to take them from 10 to 80 per cent.

The V2L is another nice addition, which allows you to draw power from the battery, if needed, to run small electrical appliances.

The XPower is hardly a car for camping but, for example, if you decided to take it to a track day and want to plug in a kettle to make a hot drink, you can literally plug it into the car. Handy!

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 real question about the XPower is not if it’s quick, because all EVs and especially those with dual motors tend to be very rapid in a straight line, but how it handles itself on a twisty road.

That’s what separates a good hot hatch from a great one, but it’s also an area EVs have struggled in, because the combination of silence, weight and just the fact they’re new and different tends to mean they lack the driving engagement of more established competition.

Hot hatches also need to play a dual role, as daily transport and weekend fun machine, so that’s another factor to consider.

So, how does the MG4 XPower stack up? Well, the unsurprising news is it’s very, very quick. The acceleration is ferocious and really shoves you back in your seat, leaving you in no doubt that it will leave most of its hot hatch rivals (with the exception of the Audi RS3) in its dust.

When the going gets twisty though the XPower feels like it lets its rivals catch back up. There are different driving modes and switching to ‘Sport’ and reducing the regenerative braking makes a notable difference to the way the XPower handles.

The steering gets heavier and it will roll and coast into corners more like a petrol-powered hatch. It makes for a very competent car, with direct steering and good road holding… but not a great hot hatch.

It lacks the engagement and excitement that the best hot hatches offer. For example, the steering gets heavier in Sport mode, but doesn’t provide any more feedback to the driver. The Bridgestone Turanza tyres do a fine job but they lack the grip of a Michelin Pilot Sport. 

The lasting impression on the driver is a car that feels quick but doesn’t leave you wanting more. The best hot hatches make you want to keep on driving and driving, that’s not the case in the XPower.

As a daily driver it’s arguably better than its rivals, though, with quiet, effortless commuting potential thanks to its electric powertrain.

There’s the usual passive safety features, including six airbags as well as the required stability controls, anti-lock brakes and the like, however the XPower also comes equipped with the MG Pilot suite of active safety features as standard.

MG Pilot includes autonomous emergency braking, lane keeping assist, lane departure warning, adaptive cruise control, blind-spot monitoring and rear cross-traffic alert.

Thanks to all of this safety gear, the MG4 range was awarded a maximum five-star ANCAP assessment, when it was tested in 2022.

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.

Like every MG sold in Australia, the MG4 XPower is covered by the brand’s seven-year, unlimited kilometre warranty, which is industry standard for high-volume brands these days.

As for servicing, the intervals are also the same as the rest of the MG4 range, which means a lengthy two years or 40,000km, whichever comes first, between visits to the dealership.

That’s much longer than your typical petrol-powered hot hatch, which has more moving parts that need servicing. 

In terms of costs, the XPower is ever-so-slightly more expensive compared to the rest of the MG4 line-up.

A minor service is the same $296 but a major service (which comes every second service) will cost you $962.

But even so, for the first six years you’ll only be up for $1554 in servicing costs, which is comparatively cheap amongst its hot hatch rivals, and only $76 more than you’ll pay for any other MG4.
