Kia K4 vs Kia Sportage

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 Sportage still feels like a super solid offering in its segment, plus the addition of more hybrid options is only going to help.

It does feel a little under-specced in the lower grades, though, considering the everything-and-the-kitchen-sink approach taken by its Chinese rivals.

I feel like I should almost whisper this bit, given it's a dirty word at the moment, but that diesel engine, it's a real peach, and if I wasn't afraid of being run out of Sydney's inner west with pitchforks, that's probably the one I'd be choosing.

Note: CarsGuide attended this event as a guest of the manufacturer, with meals provided.

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. 

All new Sportage models feature a redesigned front and rear end, but they actually have a slightly different look. There's one look for the cheaper models and then one for the top-spec cars, the SX+ and GT-Line.

The changes aren't overwhelming, though. There are fog lights in the more expensive models, but also just more use of black edging, as opposed to the silver edging that frames the bottom of the grille and rear end in the cheaper cars.

Either way, I still really like the way the Sportage has come together. The front end looks bold and powerful, mostly because of the vertically stacked headlights and and the DRLs that really frame the front end, but they've also done a good job of making a fairly big and spacious SUV feel small and not too imposing.

Now, inside the top-spec cars it’s very modern Kia, with a big twin-screen setup, and the dual-function bar beneath them that handles things like climate control, but also mapping and media and those kinds of functions. The cheaper models also get the same look, but swap the second 12.3-inch screen for a smaller driver display.

It means you don't have to dig through the screen for everything, which is always a nice touch. And I also like some of the materials used in the GT-Line, too, like the synthetic wood grain that’s actually nice to touch.

But there are a couple of key downsides. Not quite so much in the top-spec cars, but in the cheaper versions. I hate those constant reminders that you didn't spring for a more expensive model, and there are plenty of those in the lower-spec cars.

In the more expensive models, there are buttons alongside the gearshift, but in the cheaper cars, those buttons are still there, just blacked out and inactive. And even the cutout for the head-up display still exists in the cheaper cars, but of course, there's no head-up display.

All of that combined with some hard and scratchy plastics front and back makes you really want to dig deep for a more expensive Sportage.

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.

The Sportage measures 4685mm long, 1865mm wide and between 1665mm and 1680mm tall, depending on the trim.

Slip into the backseat of the Sportage and you’ll find legroom is ample, at least for my 175cm frame, and headroom is ok, without being great - though our test car had the sunroof fitted which could be eating into the space.

Elsewhere in the back though, even the top spec GT-Line just doesn't feel that plush. And by that, I mean some of the materials are a bit hard and scratchy, you don’t get your own temperature controls for the air vents, and it generally just lacks a premium air.

Now, to the all-important point in this segment, and that is boot space. The official VDA numbers are 543-1829 litres for the petrol and diesel cars, and 586-1872L for the hybrid, but the real-world reality is a boot that is deep and wide and really has enough space to carry plenty of groceries.

But there is an important caveat. Under the flat floor there is a temporary spare wheel in the hybrids, where in some of the ICE cars, you get a full-size spare wheel.

There are a lot of different numbers involved in the Sportage story. In fact, there are no less than 13 trim and powertrain combinations, and so 13 different prices you can pay. Easier, I think, if I just pop the graphic up on screen and you can jump to the one you want.

While there are four engines and five powertrain configurations to choose from, not all of them are available across all four trim levels. The SX+, for example, offers no electrified options, while the SX will give you hybrids, but no turbo-petrol choice.

The range opens with the S, which gets 17-inch alloys, LED DRLs, power-folding mirrors and roof rails, while inside there are cloth seats, power windows, a smart key with push-button start, and single-zone air-con with rear-seat vents. Tech at this level is handled by a 12.3-inch infotainment screen with wireless Apple CarPlay and Android Auto, but no wireless charging, which pairs with a six-speaker stereo. The driver then gets a 4.2-inch screen to deliver driving info.

The SX then adds 18-inch alloy wheels, dual-zone climate, standard navigation and rain-sensing wipers.

The SX+ is feeling like a sweet spot, adding 19-inch alloys, LED fog lights, artificial leather seats that are heated up front, wireless device charging, a heated steering wheel and a better Harman Kardon Premium stereo.

Finally, the flagship GT-Line gets the lot, with 19-inch black alloys, or 18-inch wheels in the hybrid, welcome lights, projection headlights, a twin-screen cabin which adds a second 12.3-inch screen for the driver, a powered driver’s seat and a head-up display.

All models also get Kia Connect, which gives you remote access to the vehicle for things like pre-setting the climate, as well as Over the Air updates.

I’ve got to say, though, the flagship Sportage offers largely what the cheapest version of most Chinese SUVs offer, showing just how much price pressure the newcomers are putting on the old guard.

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 about this mid-life update for the Sportage is the expansion of Kia’s hybrid powertrain, which is now available with AWD, and the inclusion of an eight-speed automatic for the 1.6-litre turbo-petrol variants.

Elsewhere, the 2.0-litre petrol option produces 115kW and 192Nm, pairs with a six-speed automatic, and drives the front wheels. The other pure petrol option is a 1.6-litre turbocharged petrol unit that produces 132kW and 265Nm, paired with an eight-speed auto and powering all four wheels.

Then comes the diesel, which is a 2.0-litre unit making 137kW and 416Nm. It pairs with an eight-speed automatic and powers all four wheels.

Finally, there’s a hybrid option, now with two- or all-wheel drive. It pairs a 1.6-litre turbo-petrol engine and a six-speed automatic with an electric motor and a 1.49kWh lithium-ion battery to produce a total 173kW and 367Nm.

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.

All pure ICE Sportage grades are fitted with 54-litre fuel tanks, while the hybrids get 52-litre tanks. But the hybrids more than make up for it when it comes to fuel efficiency, with the FWD sipping a claimed 4.9 litres per hundred kilometres on the combined cycle, while the AWD drinks 5.3 litres.

The diesel is the next most-efficient, using a claimed 6.3L/100km combined, while the turbo-petrol needs 7.5 litres, and the 2.0-litre petrol requires 8.1 litres.

Our calculations suggest that, taking the fuel claims at face value, a 2.0-litre petrol Sportage should carry you 666kms on a full tank, while a turbo-petrol will take you 720kms. The diesel should deliver 857kms, while the FWD hybrid (1061kms) and AWD hybrid (981kms) will take you the furthest.

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).

I want to start this with just a small caveat. It hasn't been the most comprehensive drive of this car so far. And remember, there are a lot of variants.

Petrol, diesel, hybrid, two-wheel drive, all-wheel drive – we haven't driven all of them, and so I feel uncomfortable giving you my rock-solid verdict across the whole range. I can, however, give you my first impressions.

The first of those is that whoever in the vast Hyundai group came up with adding a long-hold function to the stereo mute button deserves a medal. By far the most annoying of the modern safety systems is the overspeed warning, which inevitably reads some signs incorrectly, others not at all, and has no idea when school zones actually start.

Thankfully, Kia, like Hyundai, now has the shortcut to mute it. You just long-hold down mute button and voila, the bing-bongs vanish.

Now elsewhere, as is pretty typical of modern Kias, the ride in this car feels properly well sorted. We've taken it through the city, onto the freeway, along a little twisting road section, and on some typically coarse and broken country B-roads, and the Sportage handled them all really well.

And even when you're getting a little frisky with the driving, there's little in the way of body roll, with the Sportage feeling planted and solid.

I wasn't totally blown away with the refinement in the cabin. On the wrong road surface, you definitely get a bit of road noise in the cabin – mind you, that is pretty hard to avoid on the coarse chip stuff – but you can also hear the engines revving away and working hard when you put your foot down.

That said, the way the gearboxes channel that power is smooth and easy, and when you put your foot down in each of the powertrains we tested, there's certainly enough urge to get you up and moving.

And that is especially true in the diesel, which I do think is a bit of a peach of a powertrain – super torquey and super easy to get the Sportage up and moving. It might find itself on the endangered species list, that engine, so get it while you can.

Now, one small downside. While the ride hasn't changed, at least for any of the ICE-powered cars, the steering has changed for all of them, and at speed, it's really lovely. It's quite direct, confidence-inspiring, and nicely weighted.

But at low speeds it can feel a little bit darty, like it takes a really big bite when you put a little input in, and it takes a little bit of getting used to.

All Sportage models start with seven airbags, and even the cheapest S gets a pretty full suite of safety stuff, including a new SOS button should you have an accident, auto emergency braking (AEB) with junction sensing, blind-spot monitoring, lane keep and lane follow assist, a rear-view camera and the often-infuriating speed limit monitoring.

From the SX+ and up you also get Kia’s Highway Driving Assist, which pairs active cruise with a lane entering function, and the GT-Line also gets remote park assist, which allows you to remotely drive into or out of tight spots, along with a blind-spot view monitor and a rear-view monitor.

The Sportage wears a five-star ANCAP rating, which it earned back in 2022.

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.

All Kia models also get the brand’s seven-year, unlimited-kilometre warranty, seven years of capped-price servicing and, should you service with Kia, eight years of roadside assistance.

Turbo-petrol and hybrid models require servicing every 12 months or 10,000kms, where the rest are 15,000km intervals. The Kia website has the full costings for each powertrain choice, but for reference, seven years of hybrid ownership will cost you a not-insubstantial $4510.
