Mazda CX-8 vs Kia K4

What's the difference?

So, what did my family think about the Mazda CX-8 GT SP diesel all-wheel drive? I love how it performs on the road - it's super easy to drive and you don't notice how large it is in a car park.

There are some great family-friendly features scattered throughout and I like how practical this is too with the extra seats and top-tether points. The multimedia system isn’t my favourite and I would have preferred to have seen a few extra airbags and a 360-degree view camera, but overall, it’s a good family car and gets an 8.0/10 from me. 

My son loved the sun blinds and the cool colour of the seats. He also gives it an 8.0/10.

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.

To be honest, I can't really tell the CX-8 and CX-9 apart on the road. They're both large SUVs that sport the classic Mazda bonnet - sharp and long. Up close, the CX-9 has a bulkier shape but otherwise they are remarkably similar.

The CX-8's darkened grille generates some interest with its lattice-work and there are enough shiny chrome accents scattered about the car that it looks pretty.

Yet, the sporty sharpness that Mazda is known for is still hinted at with its shaping and the 19-inch black alloy wheels.

Our model is finished in 'Platinum Quartz Metallic' and it is the highlight for the exterior styling for me. I think because it's such an interesting colour to look at - it varies a lot depending on lighting conditions. Sometimes, it almost has a sheen of pink to it and at others, it looks like pearly sand.

The interior looks polished and refined with its burgundy leather trim and soft-touchpoints. Again, there is a lot of chrome inside to make otherwise dull features, like air vents, pop out.

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 CX-8 is a very practical family hauler because there's ample room in all three rows. Yes, even adults will be able to squeeze into that third row without too many complaints!

All rows enjoy well-cushioned seats and up front they are electrically adjustable, but unfortunately, only the driver's side has lumbar support.

The middle row can slide forward manually or by using the electric button found on the side of the seats... but doing it yourself is way faster.

They do slide far enough forward that you won't embarrass yourself too much when you have to clamber into the third row. Where the seats have a 50/50 split-fold and manual adjustments (accessed via the boot).

In the first two rows there are lots of individual storage options but the front enjoys the most. The middle console is deep enough to be useful and I like the dual opening lid. Each row gets a couple of cupholders and drink bottle holders, too.

The charging options are great, with each row getting two USB-C ports and the front getting a wireless charging pad and 12-volt socket.

All of the controls and dials feel within easy reach and the 10.25-inch touchscreen multimedia system graphics are clear.

You can use it as a touchscreen or opt for the rotary dial but switching between the two was awkward for me. Especially, since the touchscreen function is disabled when you are using the wireless Apple CarPlay. This also has wired Android Auto, for those users. 

The amenities are practical throughout with a dark headliner, three-zone climate control and heated outboard seats and retractable sun-blinds in the middle row.

Good news for families because there are five top-tether points across the back rows and ISOFIX child seat mounts on the outboard seats in middle row, in case you need them.

You can fit a 0-4 rearward facing child seat and it shouldn’t impact on front passenger comfort. 

My six-year old found it super easy to get in and out of this car because of the 205mm ground clearance and wide door apertures. He enjoyed the high seating position, too, but was disappointed he couldn’t see out of the sunroof!

The boot space is a bit cramped with all three rows are in use at 209L but folding the third row opens up a more respectable 775L - perfect for the average family and its stuff!

The loading space is level, with the temporary spare tyre and clever storage compartments housed underneath. There is a retractable cargo blind and net, luggage anchor points and a 12-volt port, too. 

And, as always, I love a powered tailgate, which this has!

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!
