What's the difference?
Kia has launched a new small sedan - the K4 and it replaces the popular Cerato model for our market. A hatchback sibling arrives sometime later this year as a contender against the Toyota Corolla.
With a design that's sharper and far sportier-looking than the model it replaces, will it prove to be as successful?
We're in the flagship GT-Line grade to see what this new sedan has to offer and whether it's a good fit for urban dwellers who don't want another SUV.
Zeekr is making waves in Australia at the moment but it's not because of the car you see before you.
Nope, it’s the 7X mid-size SUV that’s captured a heap of attention and a whole lot of sales. In fact, of the 1832 sales the brand has managed over the first three months of 2026, just 54 were for the X.
But that was the old X and this is the new one. With more power, more performance, faster charging and a whole heap of pretty special equipment, especially for the small SUV segment.
So, is that enough to finally put the X on the map?
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.
It's a good thing in a small package, this Zeekr X, and there are a lot of things I like about it. In fact, the only sticking point for me is the price. But that's all about perspective. If you see this as a newcomer Chinese brand, then yes, there are a lot of more affordable options out there. But if you see it as a premium player, it's really a more affordable version of a Volvo.

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.
The visual changes aren’t massive. This AWD version welcomes a couple of new exterior colours, including the 'Matt Khaki Green' of our test car. It also gets the two-tone black roof and there are new 20-inch alloy designs.
Elsewhere, it's the futuristic-style of design we’re used to which differentiates the X from its Volvo EX30 twin under the skin.
Inside, this is a seriously well-equipped and polished-feeling small SUV, and — unlike some of the newcomer brands to Australia — it all feels very high quality and well put together. And that includes the material choices.
I don’t even hate the fact that most of the functions are controlled via this screen, thanks to the little shortcuts glued to the home screen. I do, however, hate the fact that there’s no easy way to change the wing mirrors or shortcuts for toning down some of the safety stuff.
That aside, though, it’s a nice and high-quality feeling space.
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.
You know you're in a small vehicle when you can't fit two large (not those crazy American-style jumbo cups, just normal coffee-shop takeaway) coffees in the cupholders, but so it is with the Zeekr X.
The small SUV's 4432mm length, 1836mm in width and 1566mm height doesn't leave much room to spread out up front. There's ample room for driver and passenger, of course, but we are talking about a small vehicle here.
Clever storage helps to mitigate that, though, especially the super-deep storage space in the centre console and the very clever fridge that separates the driver and passenger seats.
Weirdly, though, the space doesn’t feel overly tight in the back seat. We had a massive baby seat in there, and that fit without issue. And full size humans can genuinely get pretty comfortable. I'm 175cm, and I had enough knee and headroom.
In the boot, there’s 404 litres of volume with the rear seats upright and 1247 litres with them folded flat. And it’s worth pointing out this isn’t intended to be a family car, but there’s certainly enough space for the shopping... and a pram.
The new K4 sedan is offered in four grades - the base-model S which has an optional 'Safety Pack' available, the mid-spec Sport and Sport+ grades and the flagship GT-Line, which is the model on test for this review.
The GT-Line is sharply priced at $42,990, before on road costs. This positions it in the middle of its small sedan rivals, the Hyundai i30 N Line Premium ($41,500 MSRP) and the Mazda3 Astina ($43,310 MSRP).
What the K4 GT-Line has going for it over its peers is a standard specification list that features some heavy-hitting technology.
This includes dual 12.3-inch displays, a 5.0-inch climate display, built-in satellite navigation with 10-years' of map updates, wireless/wired Apple CarPlay and Android Auto and dual-zone climate control.
Charging is taken care of by two USB-C ports for each row but the front row also enjoys a 12-volt socket and fast wireless charging pad in the dedicated phone cradle.
There's also an eight-speaker Harman Kardon sound system, over-the-air updates, digital radio, AM/FM radio, Bluetooth connectivity, and a 'Sounds of Nature' soundscape for added ambience.
The Kia Connect app is also included and this allows user access to the emergency call functionality (e-Call), remote control functions for the vehicle, as well as vehicle status monitoring.
Premium equipment includes a tilt and slide sunroof with electric sunshade, two-tone synthetic leather upholstery, heated and ventilated front seats, an electric drivers seat (with two-position memory function and adjustable lumbar support) and a heated steering wheel.
For a small sedan, it comes packed with features!
This is a small SUV with a LOT of stuff. There are two trims in the Zeekr X range – the entry-level rear-drive model is $48,900, drive-away, while the all-wheel drive version we've tested is $57,900 on the road.
The obvious comparison is to the Volvo EX30, which shares its platform with the Zeekr X through both brands' Chinese parent company Geely.
As of right now, the cheapest single-motor Volvo is $56,051, drive-away in NSW, or $49,990 plus on-roads, making the Zeekr version much, much cheaper.
Anyway, outside there are 19- or 20-inch alloys, though our test car is fitted with the optional 20-inch black alloys, paired with a black-with-red-highlights interior treatment, which adds $2000 to the price.
Ours is also fitted with the electric front doors which open or close at the push of a button, and back doors that unlatch, but don’t fully open, the same way, which adds another $2000.
Both trims also get heated and cooled front seats, and heating in the rear window seats, but this AWD version also adds a massage function for front seat riders.
There’s also wireless charging, a 13-speaker Yamaha sound system and — very cool, literally — is the little drinks fridge between the front seats in the AWD variant.
Tech is handled by a 14.6-inch touchscreen with Apple CarPlay and Android Auto and there’s a head-up display for the driver.
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 big news here is a more powerful rear motor – meaning you get more grunt whether you opt for the rear-wheel drive or this all-wheel drive.
In rear-drive form, that boosts your outputs from 200kW to 250kW, dropping the sprint to 100km/h to 5.6 seconds. In AWD guise, your new outputs are 365kW (up from 315kW) and 573Nm, and your sprint to 100km/h falls to 3.7 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.
This is where it starts to get weird. The rear-drive Zeekr X is fitted with a 61kWh LFP battery, which can accept up to 230kW DC fast charging, taking you from 10 to 80 per cent charged in just 18 minutes. Total claimed range is 405km.
The flagship AWD, though, charges at a slower rate. It gets a 66kWh NMN battery and can only be charged at 150kW, meaning the same charge takes 30 minutes. Zeekr is promising a 415km driving range between charges.
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).
Short answer? Pretty good, with some caveats.
I'm partial to a firmer ride. I find some Chinese car companies can feel like they get their suspension bits from Captain Snooze, such is the soft, pillowy ride served up. And to be honest, it makes me a little seasick at times.
The Zeekr is not like that. It has firmness dialled into the ride equation and can feel harsh at times, but also improves the drive experience, delivering connection and engagement at the cost of some sharpness on the wrong road.
It's also faster than the model it replaces, but it's also one of those cars in which the real-life feeling doesn't quite match the on-paper promise.
This thing serves up supercar speed, but it doesn't feel like it from behind the wheel. Instead, the acceleration - especially from a rolling start - feels potent, but not biblical.
From a standing start it pauses for a moment, almost like an internal-combustion vehicle might, before delivering a quick (but not stratospheric) flow of power. None of that is a bad thing, by the way. Who wants their small SUV to accelerate like a supercar?
It's otherwise an entirely pleasant drive. The cabin is serene and quiet and it's a small car that doesn't feel like one. There's nothing light or tinny about the drive experience, instead there's a heft and quality.
The Kia K4 has just been launched and hasn’t been tested by ANCAP yet, so is unrated but Kia is hustling to get it tested so it can join in on their strong five-star performance record. The K4 has seven airbags, including a front centre airbag.
The K4 GT-Line has all of the bells and whistles when it comes to safety equipment and includes the big-ticket items like blind-spot monitoring and collision avoidance, intelligent seatbelt warning (all seats), rear cross-traffic alert, front cross-traffic alert, lane keeping aid, lane departure alert, leading vehicle alert, emergency call functionality, side exit warning, rear occupant alert, traffic sign recognition, driver monitoring and alert, LED DRLs, dusk-sensing LED headlights, front/rear parking sensors and a reversing camera with dynamic guidelines.
The K4 GT-Line has AEB with forward collision warning, car, pedestrian, cyclist, and junction crossing detection.
The rear seat has two ISOFIX child seat mounts on the outboard positions and three top tether anchor points but two seats will fit best.
Kia has become well-known for having annoying sound alerts in their cars and while the K4 has them too - you can easily disable the most annoying one, the traffic sign recognition, by holding the steering wheel volume button in for a few seconds.
The Zeekr X wears a maximum five-star ANCAP safety rating, earned in 2024, which means the long list of required active safety stuff is present and accounted for, all wrapped up in what Zeekr calls its 'Intelligent Driving Assist System'.
There are five cameras, five radars and 12 sensors, which is a crazy number for a car this small.
And this is also not a car in which I was desperately trying to figure out how to deactivate any of the active safety systems – save the overzealous over-speed warning – which is a win these days, too.
There are also seven airbags, including a centre front airbag.
The Zeekr X is fitted with ISOFIX anchors on the rear outboard seats and top tether anchorages for all rear seating positions.
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.
Zeekr's coverage is an underwhelming five-year, unlimited-kilometres, while the drive battery is covered for eight-years or 160,000km. There’s five years' of roadside assistance thrown in, too.
Service intervals are 20,000km or 12 months, with five years' of ownership setting you back a hefty $3072; an average of $614 per workshop visit.
There are currently 16 Zeekr dealers in Australia - two of which are 'pop-up' sites rather than full retail centres.
Multiple locations in Melbourne, Sydney and Brisbane with the ACT, Adelaide and Perth also covered. Others include Geelong and the Sunshine Coast but so far you're out of luck in Tassie or the NT.
