Kia K4 vs Gac Aion Ut

What's the difference?

The new Kia K4 GT-Line has a lot to offer - an interesting design, lots of features and a pleasant driving experience. It’s not without its quirks and there are times when a more powerful engine may have improved it for me as a long-term prospect as I do some big kays every year but it ticks the boxes as a friendly urban dweller.

The Aion UT is a cleverly-specified little hatchback and a great entry-point into electric motoring. The software needs a bit of work from a usability perspective, plus the spongy ride and cutesy styling might not be for everyone. 

However, with strong points including driving range, cabin space and value, there’s even a pitch for it in some cases to be an only car compared to most of its price rivals, which are more likely to be thought of as a second car runabout in a two-car garage.

The pick of the range is definitely the entry-level Premium. It comes in at a headline-grabbing price with specs to blow rivals out of the water, while only missing out on a few luxuries.

Have to admit I wasn’t convinced on the design of this new sedan at first as it can look a little out of sorts from certain angles. But the more time I spend with it, the more I appreciate its sharp lines and sporty rear shaping.

The small sedan market doesn't have a lot of options now because SUVs are so popular but it's nice to see a design that stands out and the fang-like LED light design at the front and rear, as well as the 18-inch alloy wheels make the K4 look very cool.

The rear doors look sleek because the handle has been hidden in the C-pillar and the K4 is particularly striking in our test model's 'Wave Blue' ($600 RRP) paint colour.

Head inside and you'll find a cabin that looks slick with a two-tone synthetic leather upholstery that feels supple underhand and a plethora of soft touchpoints under all the bits that touch.

The black headliner creates a posh space but the sunroof helps the cabin to feel airy when you need it to.

The dashboard isn't too wide, preferring a sharply linear shape and is headlined by a massive display panel that houses dual 12.3-inch screens and a 5.0-inch climate panel.

There is still a strong presence of plastics inside but you don’t tend to focus on them.

Unlike some other new cars hitting our market, the K4 hasn’t done away with its buttons and dials - and there’s enough to satisfy those who don’t like to rely on a screen for everything. The extra traditional element of the physical gear selector adds to its charm as well. 

GAC tells us the UT hatch was designed in Milan, Italy, but it also isn’t ashamed of the Chinese influence on its overall appearance, like the ultra-short bonnet and Chinese city-car style face.

Along the side it has a modern, aerodynamic profile, and the ultra-short overhangs and long wheelbase maximise the amount of room for batteries under the floor and interior space.

The rear feels a lot like a modern Mini, with its bulbous tailgate and protruding light clusters, spiced up with a sporty spoiler piece jutting out.

It’s not a bad looking thing and it’s available in an array of fun colours.

On the inside it seems to follow the established rule-book of Chinese automakers, with plush trims, big screens with minimal physical buttons as well as a contemporary two-spoke steering wheel.

There’s a trendy floating console which hosts the cupholders and wireless charger on the Luxury grade, and an array of interesting patterns and textures through the doors and dash which you wouldn’t have once seen on a car at this price-point.

However, it is worth noting that while the seats are quite nice, and the steering wheel is a stand-out touchpoint, the trims on the doors and across the dash-top are hard plastics, more so than some of this car’s rivals.

The K4 feels big for the class, especially compared to its nearest rivals and that translates to a cabin that feels adult-friendly in both rows. An impressive feat for a small sedan.

Access is the only time you will have moments of 'I should have opted for an SUV'. That's because you will get in your daily squats sliding in and out of the K4 due to its 140mm ground clearance.

The rear doors also feature a wide wing that juts out from the door handle and it catches your hip almost every time you go to close the door.

The wide front seats offer lots of comfort with thick padding and long under-thigh-support. The driver's side is powered with adjustable lumbar support but the passenger seat only offers manual adjustments, which is surprising for a top-grade model. However, both front seats enjoy heat and ventilation functions.

The back bench seat offers similar comfort to the front with seat padding and length but it's not terribly wide and two adults (or child car seats) will fit best.

Amenities and storage is decent for the class with each row enjoying four drink holders and two USB-C ports. Front rowers also get a wireless charging pad and 12-volt socket.

In the front there is a large glove box that fits more than just an owner's manual, a mid-size middle console and a centre console that features retractable cupholders to open up the space if you need to. A dedicated phone cradle with small spaces on each side rounds up individual storage for the front.

In the rear there are two map pockets, a small item cubby next to the USB-C ports and a pair of directional air vents, reading lights and a fold-down armrest.

The boot space is massive for the class at 508L (that's nearing mid-size SUV territory) but the aperture is narrow and I couldn't fit my big booster seat through the opening.

The boot is quite deep as well and you may find yourself climbing into it to retrieve items that roll into the back.

The rear bench seat has a 60/40 split which can help with storage and there is a temporary spare tyre underneath the floor.

While you don't get a powered tailgate in this model, the lid isn't heavy to operate and has a proximity opening function that keeps it practical when you have your hands full.

This just means when you approach and stay near the boot with the key fob on your person the boot lid will pop open for you.

The 12.3-inch touchscreen multimedia system looks great with crisp graphics and a responsive touchscreen. The menus are in an easy-to-understand layout which you'll get accustomed to in no time. The 5.0-inch climate display sits to the right of this system and it's nice to have it on display all the time.

The 12.3-inch digital instrument cluster isn't all that customisable but it's easy to read with large text and a small menu screen that shows nav directions, trip info or a compass.

The built-in satellite navigation system is easy to get going and to cancel a route guidance, it's a one button affair which is great for when you're on the go.

The system features wired and wireless Apple CarPlay and Android Auto. The CarPlay is simple to connect to and retained a steady connection this week with feedback from my callers that my voice was clear on calls.

In terms of interior space, the Aion UT stands out with its spacious cabin. At 182cm tall, I am easily able to find a comfortable seating position, and visibility out the front sides and rear, while not as good as some small SUVs, isn’t bad.

There’s lots of headroom, and while I mentioned the hard plastic door cards before, there’s enough padding everywhere your elbows are going to touch to make it feel a bit nicer than perhaps it is.

The main drawback of this car for me is the lack of tactile buttons and the frustrating software.

The main screen isn’t particularly well utilised, being taken up by either a background or the navigation map, with an array of typically small shortcuts across the bottom for important features like the climate control or settings menus.

You can pre-set a few information panels which sit above the shortcut bar as in many rival cars and there’s also a shortcut tray which can be hosted on the driver’s side and configured with a variety of shortcuts and settings.

It’s just a bit clumsy to use, and the array of poorly-labelled settings menus for things like active safety equipment feel needlessly complicated.

I’d love to see this car with physical controls for climate and multimedia to make it easier to live with.

Up front the storage is decent. There are big pockets in the doors and a large storage tray between the driver and front passenger thanks to a flat floor. There’s also a slightly weird storage box under the touchscreen which has a net inside, good for more delicate objects you don’t want flying around the cabin.

On the floating console there are two cupholders which are a bit too shallow for my liking, and the wireless charger feels almost pointless because its made of a hard plastic, so your phone just slides right off in the corners. The cabled outlets are hidden beneath which allows for tidy cable management and the centre armrest console box is a healthy size.

The rear seat is comparatively basic, although touches on the key points. Its main advantage is how generous the space is. My frame was able to fit behind my own driving position with heaps of room for my knees, and just enough room for my head despite the dip in the roof for the sunroof shade in the Luxury-grade car we tested. There may be even more headroom in the base car.

The flat floor makes the space useful even for three across in a pinch and there’s a drop-down armrest with (again, shallow) cupholders. There are pockets on the back of both front seats and smallish pockets in each door. The array of soft trims continues, too, and the back of the centre console features a partially adjustable air vent. Luxury spec cars get a single USB rear power outlet.

As with many Chinese cars in this segment, the generous rear seat space comes at a cost to the boot. It measures just 321 litres, which is slightly smaller than its main opponents in this category, although larger than some hatchbacks like the Toyota Corolla, for example.

It has its advantages, though. The floor is two-tiered, and can offer a flat load area with the rear seats folded down, or a deeper boot in its lower position. Underneath there’s a cutaway good for charging equipment and the tyre repair kit (sorry, no spare wheel in here).

Unlike some EVs, the Aion UT doesn’t get a frunk (front boot) for additional storage.

The GAC Aion UT starts from $31,990, before on-road costs, for the entry-level Premium grade, which makes it the third-most affordable EV you can buy in Australia after the city-sized BYD Atto 1 and the entry-level version of the BYD Dolphin.

It sits closer to price-parity with the GWM Ora, but is significantly more affordable than the rear-drive MG4 and more spec-competitive top-grade BYD Dolphin.

The bigger threat to the Aion UT is that a lot of buyers will be willing to spend slightly more to get into one of the most affordable electric small SUVs, like the BYD Atto 2 or Jaecoo J5.

Still, GAC makes a solid pitch for its hatch, which offers a higher spec level than its most direct price rivals.

For example, the Aion UT is more powerful than the entry-level Dolphin and Ora while offering a higher level of interior equipment. 

Even the just-arrived front-drive MG4 Urban also starts at $31,990, but that’s for a version with significantly less driving range.

In fact, I’d go so far as to say the entry-level version of the Aion UT (the confusingly-named Premium) is probably the pick of the two variant range.

Standard equipment levels on this car include 17-inch alloy wheels, LED lighting all around, synthetic leather interior trim with heated and power adjust front seats, a 14.6-inch multimedia touchscreen with online connectivity and built-in nav as well as wireless Apple CarPlay and Android Auto.

There’s also an 8.88-inch digital instrument cluster, heated steering wheel and the full array of safety kit.

With the same power and battery size, this leaves only arguably unnecessary luxuries for the Luxury grade, like a wireless phone charger, ventilated driver’s seat, auto dimming rear vision mirror with auto power folding wing mirrors, a powered tailgate and of course, a panoramic sunroof (with shade!).

The flagship grade is front-wheel drive and has a 1.6-litre four-cylinder, turbo-petrol engine that produces up to 142kW of power and 265Nm of torque giving this a more powerful presence than its non-turbo siblings (which only produce up to 112kW/192Nm).

However, while the power is adequate for the GT-Line there are times when the engine sounds like it's working a bit too hard.

The eight-speed torque-converter automatic transmission can also become flustered as it moves through the lower gears, especially when you’re accelerating quickly.

On the whole, the power delivery and outputs are more than enough for a city environment and the odd road trip.

The Aion UT has a front-mounted electric motor producing 150kW/210Nm. That’s plenty punchy for any hatchback at this price, and I like the way the brand hasn’t messed around with a sub-100kW motor in the base variant to push prospects towards the top-spec car.

It’s more powerful than all of its closest rivals and at the time of writing you’ll have to spend four to six thousand dollars more to get into something equivalent from BYD, Chery, Jaecoo, Leapmotor or MG.

It even has a claimed 0-100km/h sprint time as low as 7.3 seconds.

With an official combined (urban/extra-urban) cycle fuel usage figure of 6.7L/100km and a fuel tank size of 47L, this model has a theoretical driving range of 701km. That does sit around 80 kays less than some of its rivals but it’s still sufficient for those wanting to do the odd road trip!

My on-test fuel usage has popped out at 9.2L/100km, which is based on figures achieved at the pump (32.05L) and my km travelled (348km).

I’ve done mostly urban trips this week with one longer open-road drive and overall I’m not too surprised by that figure because I’ve been pushing it hard but it could be better.

The K4 is a simple gal because Kia recommends a minimum 91 RON unleaded petrol to be used for all models.

The Aion UT has a 60kWh lithium-iron phosphate (LFP) battery pack, which grants it a WLTP-certified 430km of driving range.

That’s more than its closest rivals, like the entry-level Ora Standard Range (310km), BYD Dolphin Essential (410km) or BYD Atto 2 (345km).

Claimed efficiency is 16.4kWh/100km and the car I tested returned a consumption of 14.0kWh/100km over a 130km route of mixed conditions, which isn’t bad at all.

Charging speeds are less impressive, but realistically appropriate for the relatively small battery. The peak DC charging capacity of 87kW means a charge time which the brand quotes at 24 minutes, but this is from 30-80 per cent. Expect closer to 40 minutes for a 10-80 per cent charge.

AC charging is decent, at 11kW. This should have you charging from 10-80 per cent between four and five hours.

As mentioned earlier, the power is adequate to move this car around on the open-road but you have to be a little aggressive on hills to keep your speed consistent.

It’s not always quick off the mark, though, and you’ll notice that when you have to cross traffic or enter a roundabout - so allow for extra car lengths. Once you get going, it’s responsive in the city.

The steering is sports-stiff and so is the suspension. This makes the handling feel nimble in turns and sure-footed when doing quick lane changes but you hear and feel every bump in the road. 

On-road comfort is okay around the city but the road noise is very loud inside the cabin and is particularly noticeable at higher speeds. You’ll have to raise your voice to chat to passengers in the back when you're on the highway.

The K4 has a small turning circle of just 10.7m and you can easily do a U-turn in spaces that others might have to do a three-pointer. This made the K4 feel friendly in small car parks and on ramps.

The direct steering makes it easy-enough to park, as does the reversing camera and front/rear parking sensors but I’m pretty disappointed that at the top grade-level, you miss out on a 360-degree camera system (tsk, tsk, Kia).

The drive experience can be where a lot of Chinese cars fall down but I walked away less frustrated by the Aion UT.

That’s not to say it will behave as you might expect a low-slung hatchback to. The suspension, for example, is extremely soft as it maintains its original Chinese-market state-of-tune.

This makes the car waft over imperfections on city roads. And in that sense it offers supreme ride comfort in the scenarios it was designed for. However, at the extremes, like some speed bumps, or particularly deep pot holes there can be a surprisingly violent re-bound sending a thud through the cabin.

The other trade-off for soft suspension is less body control. I was surprised to find that the Aion UT holds it together mostly well on a flat country B-road, but when undulations and big dips introduce themselves, the soft suspension can be too slow to react, making the car lose confidence in higher-speed open road scenarios we’re more used to in Australia.

The steering, like many electric cars in this category, is relatively heavily electrically assisted. This makes it light and easy to adjust at low speeds for easy park and maneuverability in the confines of a city. It loses a little bit of road-feel at higher speeds but the Aion UT’s steering is far from the least connected I’ve experienced recently.

One thing it can’t be criticised for is a lack of power. With 150kW instantaneously available the Aion UT has some serious poke and while the ChaoYang tyre package is tuned more for efficiency than grip, it’s again not one of the worst I’ve driven with.

One thing which helps the whole experience along is this car’s hatchback layout. With the weight of the battery low and squat and the wheels all the way out to the edges of the frame, the Aion UT inherently handles decently compared to an electric crossover or small SUV.

Like all Chinese cars, the UT has a host of occasionally frustrating driver aids, which you can read about in the Safety section below. While I was inclined to turn some of the features off after testing them, the alerts are relatively quiet and non-invasive.

Is the UT any good to drive? It’s not bad for the segment, I was largely pleased with how it handled and the power on offer, and while it still has its annoyances, they’re not big deal-breakers. 

The MG4 rear-drive is a better allrounder, while the GWM Ora isn’t as good. I’d say it’s on par with the BYD Dolphin, but they excel in different areas. The Dolphin's a bit sharper in terms of handling but the Aion UT is more comfortable.

As with many Chinese cars the list of active safety equipment is long but that doesn’t mean it’s particularly well calibrated.

Standard gear includes the key stuff like auto emergency braking (AEB), lane keep assist, blind-spot monitoring, rear cross-traffic alert and adaptive cruise control. There are also rarer features for an affordable car like this including traffic sign recognition, door open warning, auto high beams and front cross-traffic alert.

On the parking front you get a 360-degree parking camera view as well as front and rear proximity sensors.

There's also an annoying driver monitoring system and one I haven’t seen much in the form of an occupant warning system, which seems to imagine you’re not wearing a seatbelt when you are.

It’s not the only safety system I found myself reaching to turn off. The lane keep assist could occasionally be a bit heavy-handed and the traffic sign alert was typically frustrating. This, sadly, is what we’ve come to expect from these types of systems from many Chinese automakers.

It’s not the most annoying system I’ve used, though, and the alerts are quiet enough and far enough apart that they aren't as intrusive as they can be in some rivals. You can also adjust the tolerance of some of the systems in the (needlessly complicated) menus to make them less annoying.

At the launch, the Aion UT was yet to be rated by ANCAP.

The K4 GT-Line is offered with Kia’s seven-year/unlimited-kilometre warranty. That’s a pretty good term for the class and there is a seven-year capped price servicing program for a flat $3877 (averaging $554 per service), which is slightly more expensive than others in the class.

Servicing intervals could get annoying if you do big kays every year as they're spaced at every 12 months or 10,000km, whichever occurs first.

GAC covers this electric hatch with an eight-year and unlimited kilometre warranty, while the brand’s “magazine battery 2.0” is covered by a separate eight-year and 200,000km warranty. Five years of roadside assistance is included.

The Aion UT needs to be serviced once a year or 15,000km. The service price schedule extends all the way out to 240,000km with yearly visits costing between $199 and $640 but for the life of the warranty the average yearly cost comes in at $352.

There are currently 19 GAC dealers in Australia, confined mainly to Melbourne, Sydney and Brisbane with a single store in Perth and an outlier in Cairns. No representation yet in Tassie, Canberra, the Northern Territory or SA.
