Kia K4 vs Hyundai Kona

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.

It’s easy to see why the Hyundai Kona leads the Aussie small SUV category, with this hybrid version enhancing the car’s abilities in key areas. Sharply priced and well-specified, comfortable and practical with a hugely efficient powertrain as well as refined dynamic performance. It’s a compelling package. 

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 Kona’s exterior mixes smooth curves across its softly rounded nose and swollen haunches with sharp lines and geometric shapes in the lower grille, wheel arches and rear bumper.

And when the current, second-generation version arrived in mid-2023 it swapped out its predecessor’s already slimline LED daytime running lights for an even thinner strip running the width of the car, in similar fashion to the Hyundai Sonata sedan and Staria people mover.

The single line light signature is repeated with the tail-lights, a brake, reversing and indicator cluster confined to the outer rear edges.

Throw in a conspicuous diagonal character line across the doors, and bright metallic accents making a visual connection between the top of the tailgate and the lower edge of the side glass and there’s a lot going on. 

Always a subjective call, but I don’t mind the Kona’s design, although our test car’s ‘Mirage Green’ paint finish leaves me (and my significant other) cold.

Inside, the colour palette is uniformly grey which contributes to a restrained, relatively low-key feel, although light trim for the headliner and pillar covers brightens the mood somewhat.

The dash treatment is cool and contemporary, comprising a wide wrap-around instrument and media screen panel next to a narrow tray on the passenger side.

Fit and finish is impressive and details like perforated centre panels on the leather-faced seats dial up the premium feel.

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.

Even though the Kona measures a relatively modest 4350mm end-to-end, it offers up copious amounts of interior space. Dr Who would be proud.

Lots of breathing room up front, with the ‘shift-by-wire’ auto transmission shifter’s location on the steering column freeing up extra space in the centre console.

There’s a lidded bin between the seats (the padded top of which doubles as a centre armrest) with an open tray the size of a shoebox in front of it (which includes a pair of swivel-out bottle or cupholders) as well as a wireless phone charging bay ahead of that.

Generous bins in the doors include a recess for large bottles, plus there’s a decent glove box on the passenger side and a handy open tray above it. Plenty of room to keep the bits and pieces of everyday life under control.

Power and connectivity for the driver and passenger runs to two USB-C sockets and a (180W) 12-volt outlet.

Switching to the back is where the Tardis factor steps up a notch, the Kona offering space more in line with a next-size-up medium SUV.

Sitting behind the driver’s seat set to my 183cm position there’s loads of leg and headroom and even enough shoulder room for three adults to get to know one another on shorter journeys. A close to flat floor also helps with foot room in the centre position. Worth noting the rear seat backrests recline slightly for extra comfort options.

No door bins as such but, again, there are recesses for bottles. Netted map pockets on the front seat backs are helpful as is a fold-down centre armrest, which includes a pair of cupholders.

Individual air vents for back-seaters (in the rear of the front centre console) is always a welcome inclusion, and there’s a small oddments tray underneath them. Another pair of USB-C sockets will keep devices charged.

Boot capacity is healthy at a class-competitive 407 litres (VDA), expanding to 1241L with the 60/40 split-folding second row seat folded.

There are storage wells behind the rear wheel tubs, multiple bag hooks and four tie-down anchors to help keep loads secure.

There’s a temporary space-saver spare under the boot floor, which gets a tick over the increasingly common repair kit option and you’ll be able to tow a 1.3-tonne braked trailer (600kg unbraked).

When you’re sitting on top of the sales pyramid, everyone wants a piece of you and it feels like Hyundai has priced and specified the Kona to match the market with some special touches thrown in here and there.

At $39,950, before on-road costs ($44,738, drive-away), the Hybrid Elite’s standard equipment list is generous.

Aside from the safety and performance tech covered further down, big ticket items include leather-appointed seats and steering wheel, heated and power-adjustable front seats (10-way driver / eight-way passenger), 18-inch alloy wheels, LED headlights, tail-lights and DRLs, keyless entry and start, adaptive cruise control and auto rain-sensing wipers.

There’s also dual-zone climate control, digital radio, wireless Android Auto and Apple CarPlay, six-speaker audio, a 12.3-inch multimedia screen and 4.2-inch instrument cluster, rear privacy glass and more. 

A sneaky power tailgate and/or ventilated front seats would be nice at this price-point, but they’re by no means mandatory for the class. 

Similarly priced hybrid rivals like the Haval Jolion Ultra Hybrid ($38,990, drive-away), Honda HR-V e:HEV L ($42,900, drive-away), Subaru Crosstrek Hybrid L ($39,590, before on-road costs) and Toyota Corolla Cross GXL Hybrid ($41,190, before on-road costs) are broadly aligned with the above features list but none of them put the Kona Hybrid Elite in the 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 Kona Hybrid is powered by a naturally aspirated 1.6-litre, four-cylinder petrol engine working in concert with a single electric motor, both driving the front wheels through a six-speed dual-clutch automatic transmission.

The all-alloy engine features dual variable valve timing and direct-injection to produce 77kW at 5700rpm and 144Nm at 4000rpm, the permanent magnet synchronous motor chipping in with 32kW/170Nm for a total combined outputs of 104kW/265Nm.

That power output is in the middle of the small hybrid SUV pack and torque is at the higher end. 

Kerb weight is a fraction over 1.5 tonnes and you can expect 0-100km/h acceleration in the high 10-second range with a top speed around 170km/h.

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.

Hyundai’s official fuel consumption figure for the Kona Hybrid Elite, on the combined (urban/extra-urban) cycle is a miserly 3.9L/100km, the 1.6L engine emitting 89g/km of CO2 in the process.

Minimum fuel requirement is 91 RON ‘standard’ unleaded and with a 38-litre tank theoretical range is around 975km.

On test, over several hundred kays taking in city, suburban and freeway running, we saw an average of around 4.4L/100km, which is impressive and a big contributor to the car’s appeal.

Using our real-world test number, the range figure comes in at a still handy 860-plus km.

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 first things that come to mind when it comes to driving the Kona Hybrid are comfort, quietness and lack of stress.

From an ergonomic point of view the dash and cabin layout make life easy. There are physical controls for key functions like heating and ventilation, as well as audio and drive modes. Not a fan of the hard driver’s door armrest, though.

The engine is quiet and the transition between combustion and electric power is seamless. It’s fun to watch the (available) graphic screen in the driver’s display illustrating where drive is coming from at any given moment. Without it you’d be hard-pressed to know.

Acceleration is more than adequate and the powertrain’s bias towards electric propulsion means take-offs are ultra-smooth. 

Suspension is by MacPherson-type struts at the front with a multi-link rear set-up and ride quality is outstanding. Despite the Kona Hybrid’s relatively large 18-inch rims, bumps and ruts don’t cause major disruption and the Kumho Ecsta PS71 tyres (215/55) are exceptionally quiet.

Steering accuracy and road feel are both good and drive mode switches between ‘Normal’, ‘Eco’ and ‘Sport’ are noticeable, the latter dialling up urgency and dynamic response.

That said, we found ourselves in Eco most of the time, without any penalty in terms of throttle response or cruising ability.

Torque vectoring helps keep everything buttoned down if you decide to press on through your favourite set of corners, the front seats remain comfy on longer drives while keeping you securely located and the ‘shift-by-wire’ electronic gearshift is slick.

Physical brakes are ventilated discs at the front with solid rotors at the rear and they operate with reassuring smoothness. An active hydraulic booster controls regenerative braking, adjustable through three levels. Warning: the most aggressive setting makes the car annoyingly ‘shunty’ at slower speeds.  

Driver-assist safety tech makes its presence felt occasionally, but never to a disturbing degree… with one exception.

Despite the ability to program a steering wheel button to short-cut directly to the appropriate screen, the need to cancel an incessant and sometimes inaccurate overspeed warning every time you start the car is a pain.

A tidy 10.6m turning circle helps in slow-speed manoeuvres as do front, side and rear parking distance warnings and a high-quality reversing camera.

The Kona Hybrid is as good or better than anything in the class when it comes to the drive experience.

The Kona scored four from a possible five ANCAP stars in 2023, with particularly strong results in Adult Occupant Protection (80 per cent) and Child Occupant Protection (84 per cent).

It features a full portfolio of crash-avoidance tech, including AEB with forward collision warning as well as cyclist, pedestrian and motorcycle detection, plus car-to-car junction, crossing and head-on detection. Phew!  

On top of that, there’s lane-keeping and lane-following assist, blind-spot monitoring, driver-attention warning, rear cross-traffic alert and collision avoidance, ‘Remote Smart Parking Assist’, ‘Safe Exit Warning’, driver fatigue detection, tyre pressure monitoring and more.

If, despite all that, a crash is unavoidable there are seven airbags fitted, including a front centre bag to minimise head clash injuries between driver and co-pilot in a side collision. 

There’s also multi-collision brake (to reduce the chances of subsequent impacts after an initial crash), auto collision notification and an emergency call (SOS) function.

For baby capsules or child seats there are three top-tether points for child seats across the second row with ISOFIX anchors on the two outer positions.

All in all, a comprehensive safety offer that matches or betters the Kona’s class competitors.

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.

The Kona is covered by Hyundai’s seven-year/unlimited-km warranty (upgraded from five years mid-last year), which is ahead of the mainstream five-year warranty pack.

Roadside assistance is complimentary for the first year, with the deal extended for another 12 months every time the car is serviced at an authorised Hyundai dealer. 

Speaking of which, scheduled servicing is recommended every 12 months/10,000km, which is a little lower than the (15,000km) norm for the category. After a complimentary check up at six weeks/1500km, the first seven services (in line with Hyundai’s ‘Lifetime Service Plan Pricing’) come in at $3782, for an average of $540 per workshop visit.

That’s on the high side considering an equivalent Toyota Corolla Cross (in line with ‘Toyota Service Advantage’ pricing) will set you back an average of $354 per service over the same period.

Hyundai has a network of 185 dealers covering every Australian capital, state and territory.
