2026 Kia K4 Reviews

The Kia K4 was a massive shakeup for the South Korean carmaker when it launched in Australia last year as it ditched the popular Cerato nameplate.Launching initially in sedan guise only, the K4 hasn’t been the sales hit the Cerato was, at least yet. The K4 Hatch has now arrived and it could help correct the course.Measuring 27cm shorter overall than the sedan, the K4 Hatch has a shorter rear overhang. This makes the K4 look more European and contemporary than the more conventionally styled sedan.Another benefit of the shorter rear hangover is it's easier to park in tight parallel car spots. This can make a world of a difference to small car buyers.While shorter overall, the K4 Hatch’s wheelbase remains unchanged from the sedan. This means the almost tardis-like interior space carries over, especially for second-row passengers.Overall boot space (438L) is down slightly on the sedan (508L) but the boot opening is much larger and the space itself is squarer and usable for big, bulky items. It’s also great to still see a space-saver spare wheel under the boot floor.Another big shakeup that coincided with the introduction of the hatchback body style was a slight change to what powers the non-GT-Line K4 trims.It’s still a 2.0-litre naturally aspirated four-cylinder engine but produces slightly less power and torque (110kW/180Nm vs 112kW/192Nm). It’s also mated to continuously variable transmission (CVT) rather than a torque-converter automatic. The same set-up can be found in the Kia Seltos and Hyundai i30 Sedan, among others.While this engine has never been an outright performance beast, the CVT does make the most of what it has to offer. It’s happy to flare the revs when required to get up to speed, but you get that monotonous engine drone as there's no gear changes.At higher speeds the engine does run out of puff and it frequently needs to dip above 3000rpm in order to maintain highway/freeway speeds.Despite this, fuel consumption has improved dramatically thanks to the CVT. Kia claims it consumes an average of 6.1L/100km, versus 7.4L/100km for the MY25 K4 Sedan. In the real world I saw an average of 6.9L/100km across 350km of urban/highway driving, which is considerably better than what I got in previous testing of the K4 Sedan with the six-speed torque-converter auto.It’s disappointing the K4 still only has a 47L fuel tank which is small for the segment and means you’ll need to be refuelling more frequently.Another redeeming factor for the lack of engine power is how comfortable and dynamic the K4 Hatch is to drive. Like the sedan it has received a local ride and handling tune and that is evident in and around town, as well as on the open road.The car reacts to pimply urban roads with suppleness and even larger bumps at higher speeds don’t unsettle the ride.This is complimented by the steering which is direct and has a nice weight to make the car feel fun to drive on the open road but not too unwieldy in tight, urban streets.The K4 Sport+, which is the penultimate trim level in the line-up and the highest trim with the 2.0-litre non-turbo engine, is priced from $39,090 before on-road costs, regardless of the body style. This is getting up there in terms of price compared to similarly specced rivals like the Toyota Corolla Hybrid and Subaru Impreza.Standard equipment includes 17-inch alloy wheels, LED headlights, a 12.3-inch digital instrument cluster, 12.3-inch touchscreen multimedia system with wireless Apple CarPlay and Android Auto, a 5.0-inch climate control screen, synthetic leather upholstery and heated front seats.However, for almost $40,000 before on-road costs this K4 misses out on a wireless charger and it has a plastic steering wheel instead of a leather- or synthetic leather-wrapped unit.Beyond this, the K4 Sport+ comes with the entire active safety suite including autonomous emergency braking (AEB), blind-spot monitoring, rear cross-traffic alert, adaptive cruise control with lane centring and lane change assist, plus front and rear parking sensors and a reversing camera. Strangely a surround-view camera isn't offered across the line-up.There are also seven airbags, an emergency SOS calling function, plus ISOFIX child-seat anchorages on the two outboard rear seats and top-tether points on all rear seats.Like all Kias, the K4 is covered by a seven-year, unlimited-kilometre warranty. This is now becoming standard among mainstream carmakers.Servicing is required every 12 months or 15,000km, whichever comes first. The first seven services cost a total of $3883, which averages out to $554 per service. This isn’t cheap and you’ll pay less for servicing an equivalent Hyundai i30 or Toyota Corolla Hybrid.

I know, I know, the small passenger car segment is on its last legs in Australia. Dying, if not already dead. The eulogy is written. The hole has been dug. All that's left is to lower the few remaining stragglers into the ground.The problem is, nobody seems to have told Kia. The Korean brand is doubling (or even tripling, if you consider the Picanto) down on its passenger car offering in Australia with the launch of the K4 hatch.You're no doubt already familiar with the K4 sedan – the brand's Cerato-replacing small car that arrived in Australia at the beginning of this year. But this slower-to-arrive hatch version is the one they've been waiting for."Australians are hatchback people," the brand tells us, and so this wagon-esque body shape will be the model's best-seller. And considering the sedan managed 5942 sales to the end of November (in a segment that shrank by 23.6 per cent over the same period) that would be good news for Kia.It's worth remembering here that this is supposed to be one of Kia's entry-level vehicles, but it really doesn't look like it, does it? I love the new design language on both K4 examples, but I like this one even better, mostly because it blends Kia's future-friendly front-end design with a sportier-feeling silhouette.It also doesn't look like a hatchback, at least in the traditional sense. It might be shorter than the sedan (4440mm versus 4710mm), but the way the design seems to stretch back from the b-pillar gives the K4 hatch a kind of wagon-ish profile.Like the sedan, the K4 hatch is available in five grades, and pricing and equipment is identical across the body styles. That means no matter the shape you choose, you can have a K4 S for $32,090, an S with Safety Pack for $34,190, a Sport for $36,690, a Sport+ for $39,090 or a GT-Line for $43,790.I won't detail the full spec here, but we have a detailed article that covers all the inclusions at each price point.In hatch guise, I've only really tested the GT-Line trim, and yes, nearly $44k before on-roads is a sizeable ask, but I've got to say it does also feel quite plush in the cabin. All the materials kind of melt under the touch, and you get leather-ish seats trimmed – in my test car at least – in sharp-looking white and black.The twin-screen setup (one 12.3-inch screen for multimedia and another for driving info, with a climate control panel sandwiched between) is probably my favourite iteration of Kia's cabin layout, because not only do you get the tech, you also get a whole bunch of shortcut buttons so you don't have to go digging through screens every time you want to do something.But the big news for most of the K4 range is a new and more efficient 2.0-litre engine with a continuously variable transmission (CVT) that drops power slightly, and fuel use more significantly.The new engine and gearbox combination makes 110kW and 180Nm, compared to 112kW and 192Nm, with fuel use falling from 7.4L/100km to a more frugal six litres flat.The K4 hatch is slightly shorter and slightly lower than the Cerato that it effectively replaces, but there is some clever interior packaging, so much so in fact that Kia says you get more legroom and headroom in both the front row and the second row than you did in the old Cerato, but marginally less shoulder room in the back seat.What does that mean in real terms? It means that I think you'd actually get away with this as a family car, at least in terms of passenger space.Sitting behind my own 175cm driving position, I had tonnes of knee room and enough headroom to get comfortable. Yes, it would be tight with three adults across the back, but you could have two kids back there, or a child seat or two, easily. But it is at the boot where the first chink in that family-friendly armour does appear. The boot is 438 litres VDA, which is very solid, but not good enough to swallow a massive pram comfortably. There is, however, a space-saver spare under the boot floor, which is a tick.I'm going to have to limit my drive impressions to the GT-Line, which is possibly no bad thing. A turbocharged engine and an actual gearbox is a rarity in the world of cars these days, plus the 1.6-litre turbo and eight-speed automatic reserved for the GT-Line makes 142kW and 265Nm – both big jumps over the rest of the range.I've driven a lot of newcomer brands to the country recently, and I've got to say, really none of them shine on Australian roads the way that cars have been tuned and tested here shine on Australian roads, and the K4 hatch is no exception. It rides firmly but comfortably, the steering is nicely weighted, and there's a level of engagement to the experience sometimes lacking from the competition.Now, that's not to say it isn't without some quirks. It can feel a little bit loud and ragged in the cabin when you put your foot down. And the steering, which has a really nice weight to it, doesn't feel overly linear all the time either. When you turn into a corner, sometimes it feels like you have to have another bite at it, or less of a bite of it. It's like it turns on some lock and then a lot of lock all at once.But in terms of cruising around the city or the suburbs, this thing is comfortable, mostly quiet, and easy to live with, and it'll do pretty much what you need it to do without too much drama.But one final caveat. Before I set out to film this car for the video review above, I had to studiously make sure that all the safety systems were either turned off or turned to silent, because you just know they're going to interrupt filming with bings and bongs and chimes.That is a curse of the modern car. I really do hope they find a way to iron it out sooner rather than later, because believe me, you will get familiar with turning off the safety systems in this one, too.
