Kia K4 Review & Prices

While SUVs might have taken over the world of family cars, Kia has still launched an all-new hatchback. The new K4 is a replacement for the old Kia Ceed, and it majors on interior space, practicality and good value - though that comes at the expense of a bit of driving enjoyment.

Think of the K4 like a pair of big comfy pants. Sure, the world’s moved on a bit to bamboo fabrics and funky patterns, but there’s a lot to be said for doing things the old-fashioned way, even if it’s not very exciting. It’s usually cheaper, too.

The K4’s closest alternative is the ever-present Volkswagen Golf, but you could also consider the Hyundai i30, the Honda Civic, the Skoda Octavia, the Toyota Corolla or the Mazda 3. No doubt if you’re looking at a K4, you might also have considered a small SUV such as Kia’s own Stonic, the Volkswagen T-Cross or Toyota Yaris Cross - similar in price to the K4, but sacrificing some space for those rugged looks.

You could also look at the Kia EV4, which is the K4’s all-electric equivalent.

Approaching the K4, you can’t help but notice just how striking it looks. The bold, L-shaped LED daytime running lights are mirrored in the taillights, and there’s a neat bit of chrome detailing around the hidden rear door handles. What’s more imposing is the car’s proportions - it’s very long, wide and low, in contrast to the more upright alternatives.

The interior is just as up-to-date. It’s very similar to Kia’s other recent cars, including the EV4. The wide dashboard is topped with a trio of displays - a digital driver display, a huge infotainment touchscreen, and a slightly awkward climate control screen tucked in between them. This is usually blocked by the steering wheel but it doesn’t matter because there are separate, physical climate control buttons you can use instead.

Everything feels very well screwed-together but it isn’t the most inviting environment. Even in high-end models the materials used are very plain and dark, and a sunroof to brighten up the interior is only standard on the top-spec cars.

You can’t argue with the space on offer, though. The K4 has almost as much legroom for rear passengers as a Skoda Octavia - it’s ideal if you regularly carry adults or have lanky teenage children who need a lot of space.

The boot is also very generous - at 438 litres it’s bigger than a Volkswagen Golf or a Vauxhall Astra, and there’s an estate version coming too if you need more space. The lip to lift items over is quite high, though.

There are only two engines available in the K4, and they’re both petrol - a 1.0-litre three-cylinder or a 1.6-litre four-pot. Though there’s a little bit of mild hybrid assistance (basically a beefed-up stop/start system) there’s no option for a full hybrid or plug-in hybrid engine option, so neither of them are particularly efficient or good for company car users.

Neither make the K4 particularly fun to drive, either. It’s pretty comfortable on the motorway, and deals with bumps okay in town, but the overly light steering doesn’t give you any feedback in the bends and the body leans a lot when you corner.

Verdict

The Kia K4 is very much a head-over-heart purchase - despite the striking looks, it’s not an exciting car to own or drive. It’ll be cost-effective, reliable and practical, and that’s great. But a Volkswagen Golf feels like a more complete package, despite not having quite as much passenger space - there’s more choice of engines and trim levels, a nicer interior and it’s more fun on the road.

If the Kia’s recipe of quiet practicality appeals, though, have a look at new Kia K4 deals through Carwow, as well as Kia K4 lease deals. You can browse new Kia deals, or used Kias for sale through our trusted dealer network. Remember, you can even sell your car with Carwow.

The Kia K4 jumps in price dramatically between the entry-level trim and the range-topper. A Pure model with a manual gearbox starts at just over £26,000, while the automatic is around £1,500 more expensive. The Pure comes with 16-inch alloy wheels, LED lights, cloth seats and a rear-view camera as standard.

It’s similarly equipped and priced to the most basic Vauxhall Astra while undercutting the Volkswagen Golf, Toyota Corolla and Peugeot 308 by thousands of pounds.

GT-Line cars drop the manual gearbox in exchange for 17-inch alloys, heated seats, a wireless phone charger, sporty body kit and more advanced driver assistance tech - but cost £2,500 more than the Pure with the same engine and gearbox. The 1.6-litre version is over £1,000 more, again. GT-Line S adds larger alloys, a slide-and-tilt sunroof, ventilated front seats, Harman Kardon audio and the dual-clutch automatic gearbox.

The K4 is comfortable enough on a long trip, but it’s no fun on a twisty road and the bigger wheels don’t absorb bumps too well around town

In town

The Kia K4 feels very low down when you’re driving round town - especially if you’re used to an SUV. That’s not necessarily a bad thing, as visibility all-round is still very good, but if you like a commanding driving position then you’ll definitely want something higher-up.

All the controls are very light so it’s easy to nip around town, though the over-light clutch on manual models is a bit difficult to modulate at first. The automatic gearbox - available as an option on the 1.0-litre engine, and standard on the 1.6 - is slick enough, but a bit like Volkswagen’s DSG on the Golf it can become a bit confused if you want a quick response, such as at a roundabout.

The suspension can feel a little fidgety on bumpy roads around town. You can improve this by going for a low-spec car with smaller wheels, and thankfully Kia does offer the top-spec GT-Line S on these wheels - but only with the 1.0-litre engine.

On the motorway

Neither version of the K4 is particularly fast, but joining a motorway does feel a little bit ponderous in the 1.0-litre version as it only has 113hp - not much for quite a large car. The 1.6-litre version feels more urgent, but even the most powerful model only matches a mid-spec Volkswagen Golf for 0-62mph acceleration. So a bit of planning ahead is useful when you’re on a short slip road.

Once up to speed, the K4 is quite comfortable - only the occasional expansion joint spoils the experience. It’s not very quiet, though, despite wind noise being quite well contained there’s rather a lot of road noise.

On a twisty road

When you get onto a fast back road, the K4’s soft suspension means there’s a lot of body lean in the bends, and this combined with the light, quite remote-feeling steering means there’s not a lot of enjoyment to be had. Neither engine is much fun to wring out, either, and the automatic gearboxes don’t have the rifle-quick action of a Volkswagen DSG.

The Kia K4’s rear seats are very impressive and the boot’s pretty large too. Shame there’s a high boot lip to hoick items over

The K4 is much longer and wider than a Volkswagen Golf, and pretty close in dimensions to the Vauxhall Astra - but it’s lower than either. This gives it quite a sleek silhouette and a sporty look, but that doesn’t come at the expense of passenger space because the wheelbase - the distance between the front and rear wheels - is extremely long.

The front seats are pretty comfortable on the whole and they have a decent level of adjustment, though tall drivers might find that the pedals feel a bit too close - it’s difficult to set the wheel comfortably and not have your legs feel a bit cramped.

Storage space is good up front with a wide storage tray behind the gear selector containing two cupholders, a wireless phone charging pad, under-armrest storage and a big glove box. The door bins are quite long but aren’t wide enough for a big water bottle, and it’s a shame that there’s an old-fashioned T-bar style gear selector on automatic models rather than a space-saving column-mounted one like you get in the Kia EV4.

Space in the back seats

There’s ample room in the rear seats, with lots of legroom and headroom. It’s easy to get in with nice wide-opening doors, though the seats do feel quite low down so those who are less mobile might struggle to lower themselves in.

The seatbacks are hard, so it’s good that there’s enough room so your knees don’t have to press against them. The middle passenger has a small transmission tunnel to contend with but it’s not too obtrusive, and there’s a pair of cupholders in the fold-down centre armrest as well as two USB-C ports for charging gadgets.

Boot space

With 438 litres of space, the Kia K4 has all of its hatchback alternatives licked in terms of overall capacity. The Volkswagen Golf has 381 litres, the Honda Civic 410 litres and the Vauxhall Astra 422. It’s only the Skoda Octavia, with its cavernous 600-litre space, that beats the K4 here.

The seats fold down nice and flat, and you don’t have to contend with funny false boot floors or anything like that. The only issue is that there’s quite a high boot lip to hoick items over - and that the boot release is offset by the rear-view camera, though you’d soon grow accustomed to that.

Good quality materials and plenty of standard equipment - but it’s a bit dark and dingy inside the Kia K4

The K4’s interior will be very familiar if you’ve sat in any recent Kia. It has a huge triple-screen setup at the top of the dash, which features a 12.3-inch digital instrument cluster, a 12.3-inch infotainment screen and a 5.3-inch touchscreen between them for the climate controls.

The climate screen is pretty pointless. Not only is it almost totally obscured by the steering wheel, but most of the functions are doubled by a set of toggle switches further down the dashboard - you just have to peer round the wheel to get functions like the heated rear screen or the ‘auto’ fan speed button. A couple more switches on the centre console would be better than this.

The infotainment system has a lot of menus to scroll through, and not every function is particularly obvious. But it’s responsive and the screen is bright and clear. You can also use wireless Apple CarPlay or Android Auto to bypass Kia’s system, and the wireless charging pad means you can keep your phone topped up.

Basic ‘Pure’ models feel quite dark and dingy inside, and get a fairly unattractive two-spoke steering wheel. Step up to GT-Line and you get a three-spoke wheel and a bit of lighter trim, but the bulk of the plastics are still black.

Material quality is good, as it is in most Kias - even the cheaper plastics lower down on the dash feel dense and well screwed-together. The matte finish is also very sensible and should be more resistant to knocks and scratches than a piano-black finish would be.

Neither of the Kia’s two engines provides particularly stellar fuel economy. The best is the 1.0-litre petrol, which can do up to 49.6mpg officially and around 45mpg in the real world. That’s a way off the mild hybrid engine in the Vauxhall Astra or the 1.5-litre petrol in the Golf, though, both of which will return over 50mpg with ease.

The 1.6-litre engine gets either 43.5mpg or 42.2mpg officially, depending on which power output you go for - in the real world we saw about 39mpg from both of these. Combined with a slightly smaller fuel tank than the Golf, you’ll get about 400 miles to a tank of fuel.

CO2 emissions are also relatively high compared to its hybrid or plug-in hybrid alternatives, meaning more expensive company car tax and higher first year road tax bills.

Euro NCAP hasn’t crash tested the K4 yet. However, we’d expect a decent result - every recent Kia has scored either four or five stars, with the closest equivalent being the EV4 with a five-star result.

All models get a good amount of safety kit, including speed limit assist and lane keeping assist. Both of these can be deactivated via shortcuts on the steering wheel, though you need to go into a confusing and long-winded menu on the infotainment screen to deactivate the driver monitoring.

More annoyingly, this monitoring system is never fully off… and if it decides you’re driving like you’re tired, it’ll whack the lane-keeping system back on. That’s very annoying.

*the regular three-year warranty is extended by a year and 10,000 miles with each service at an official centre

The Kia K4 is too new to have appeared in the 2025 Driver Power owner satisfaction survey, but Kia as a whole placed a middling 18th out of 31 manufacturers - higher than Hyundai or Volkswagen but behind Toyota, Peugeot and Vauxhall.

There are few horror stories about Kia reliability, and the brand’s seven-year, 100,000-mile warranty remains one of the best in the business, though you can get longer coverage if you opt for a Toyota and continue servicing at an approved service centre.
