Kia EV6 vs Kia K4

What's the difference?

The Kia EV6 Air offers comfort, a good range of features and beautiful handling for a ‘base model’, but it is a little pricey considering its competition.

Having said that, if you’re looking for an EV that will fit the family and has a stellar safety list – this is one to consider.

My son reckons the EV6 looks 'really cool' and he loves the space in the back seat.

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 EV6 is cool and fun-looking, but being the base-model does mean you get plastic rather than body-coloured mouldings around the base of the car, which highlights its grade level.

The exterior hosts 19-inch alloy wheels and a full suite of LED lights but misses out on the upgraded Matrix headlights that the higher grades get.

The exterior's swoopy curves look aerodynamic and the chunkier rear balances out the sharper nose.

The interior looks well-made, and the mix of high-end cloth and synthetic-leather materials complement the futuristic exterior aesthetic.

The dashboard is headlined by a curved panel that houses the dual 12.3-inch tech screens and the floating centre console leans into that future vibe again.

There's a nice mix of touchscreen and physical buttons to satisfy a wide audience. Overall, while it’s not as flashy as its siblings, the cabin of the Air is very pleasant to look at.

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 space in the EV6 rivals much larger SUVs and tall families will rejoice with how much leg- and headroom you get in both rows.

The comfort for passengers is pretty good, with comfortable seats in both rows that feel well-cushioned. The floor in the rear is flat, which accommodates any middle-seaters.

Being the base grade, you don’t get electric front seats, which is a bit rough for its price point but the driver’s side does get powered lumbar support, which I appreciate on longer journeys.

Individual storage is fantastic for the class and the front gets two cupholders, a drink bottle holder in each door and glovebox and middle console. There are multiple storage nooks and a utility tray on the topside of the floating centre console (sized for items like keys, wallet, phone etc).

The large shelf underneath the centre console easily accommodates a handbag and snacks for any kids in the back (or adults, no judgement).

Individual storage in the back is as good as the front, with plenty of spots to tuck away all of the paraphernalia that kids seem to attract. There are also two cupholders in a fold-down armrest, a drink bottle holder in each door and map pockets.

On the whole, my seven-year-old really enjoys being in the back seat because of the amenities and space he has. He finds the EV6 to be an easy car to get out of but we all struggle with the flush door handles! They can be terribly annoying to use as they don’t pop out on approach or when you unlock the doors. If you have your hands full and have little T-Rex hands like me, it can be awkward to open.

What isn't awkward to use is the technology! The 12.3-inch touchscreen multimedia system is quick to respond and the system itself is easy to navigate once you spend some time with it.

The 12.3-inch digital instrument cluster is semi-customisable but not as pretty in its graphics as it could be. It has two styles to choose from - white or black, and the white is a little too sterile for my liking.

The multimedia system features wired Apple CarPlay, Android Auto and built-in satellite navigation with map updates for 10 years.

Charging options are solid with a single USB-A and and two USB-C ports up front, a wireless charging pad and a two 12-volt ports to choose from. The rear enjoy a three-pin standard house port and two USB-C ports as well.

The back seat has a 60/40 split and it's handy that you can lower them from the boot with manual levers. The boot itself is a good size with 490L when all seats are in use but you miss out on a powered tailgate in this model.

The frunk storage also offers an additional 52L, which is perfect to keep any charging cables or the tyre mobility kit stored away.

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 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!

The EV6 Air is a single-motor rear-wheel-drive that produces a maximum power output of 168kW and 350Nm of torque.

The Air has the slowest 0-100km/h sprint time in the EV6 range at 7.3 seconds, but that’s honestly enough for my little family. It still feels pretty damn zippy when you put your foot down.

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.

Officially, you get a driving range of up to 528km (WLTP) from the 77.4kWh lithium-ion battery. However, the longest range I ever saw was 480km, which admittedly is still very good.

The EV6 Air has a Type 2 CCS port, which means you can benefit from plugging into a fast charger and the accepted voltage is a whopping 800v.

On a 50kW system, you’ll get from 10-80 per cent charge in 73 minutes and on a 350kW system, which charge time drops to just 18 minutes.

Expect it to take longer on AC charging, though. To get from 10-100 per cent on an 11kW system, it will take approximately seven hours and 20 minutes. On a standard house plug ... expect it to be on charge for around 30 hours.

The Air also has a vehicle to load (V2L) capability – meaning, it has a standard house three-pin plug port available to charge larger appliances while on the go. 

The official combined energy consumption is 16.5kW/100km (WLTP), and my usage came out at 16.02kW after a mix of open-road and urban driving this week.

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.

The EV6 Air handles itself really well, it's been hit by torrential rain and didn’t skip a beat.

The Air really grips the road and distributes the power through the rear wheels evenly. Even at higher speeds, there’s no wobble and it feels stable when you accelerate. 

Steering is on the right side of firm and makes the Air feel very zippy when navigating tight city streets.

There are three levels of regenerative braking available, as well as a one-pedal function called iPedal, which is probably the best I’ve sampled and I like how responsive it is in stop-start traffic. However, when using this function on hills, I still hover over the brakes as it can still roll forward a bit. 

The cabin can get really loud from road noise at higher speeds, but it seems to come from underneath the carriage, rather than through the windows. The suspension is well-cushioned but not spongy.

Parking the EV6 isn’t an issue once you get used to the rotary gear selector and the reversing camera is super clear. You get a 360-degree system on higher grades but the Air does come with front and rear parking sensors.

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 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 EV6 comes with a leading seven-year/unlimited-km warranty. The battery covered by a separate seven-year/150,000km term, but this is a smidge shorter than some of its rivals.

You can pre-purchase either a three-, five-, or seven-year servicing program, priced at $721, $1382 and $2045, respectively. All of which are reasonable for the class.

The seven-year program runs up to a max 105,000km.

Servicing intervals are more in line with a fuel-based car at every 12 months or 15,000km, whichever occurs first.

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.
