Kia Stinger vs Mazda 6

What's the difference?

The Stinger GT-Line is a great machine. It looks good, feels good to drive and while it's not the cheapest large sedan, it's also not a Camry. With a strong European vibe, it's a nice bridge between boring-dependable and out-of-reach European. Boasting a strong link to Europe in its chassis DNA, it has it all apart, maybe, from the badge.

But Kia has a habit of doing unexpected things and the Stinger was a bold move worth making just for the halo effect of having such a cool car in the range. It has done good things for the company's reputation, as though the rest of the range isn't proof already.

So, what did my family think about the Mazda6 20th Anniversary wagon? Firstly, I like that it drives well and how many luxe features are up front. The trims and body paint look divine but there's a disconnect with family practicality in the back seat. Besides the multimedia system, which 100 per cent needs to be improved, I don't mind the retro-feeling elements in the cockpit but my husband's first comment was that it looked old.

It may be better suited to a smaller and older family that isn't carting around a stack of gear but you get a lot of features for your cash in this model. So, this gets a 7.0/10 from me.

My son didn't spend heaps of time in this one but he liked the colour of it and the seats. He gives it a 7.0/10.

The Stinger looks fantastic. I know the car has its detractors, but there's a massive Euro influence here that sits well in my visual cortex. It's maybe not as ooh-aah as the A5 or the outgoing BMW 4 Series Gran Coupe, but the Stinger can and should be mentioned in the same breath. It looks terrific, even if it is a bit fussier in the details.

From the signature grille, the low beltline, big wheels and sports coupe roofline, it looks sleek and sophisticated. 

Inside is a bit more conventional, with some real classic touches such as circular air vents, conventional-looking gear selector and a flat-bottomed steering wheel. It's cool, clean and, with the big new screen, a bit more techy-looking than before. There are lots of nice materials and the odd rogue one, but it's a good cabin that feels well put-together.

At first glance there's not a lot that separates this from its siblings, it's not until you get up close that you notice more shiny chrome accents on the grille, those special anniversary badges on the side and its limited colour options – I hope you like red or white, as those are your only choices!

The wagon manages to look sporty with its 19-inch alloy wheels, full LED exterior lights and the classic protruding nose that Mazda seems known for now.

It's far more obvious in the interior though with the beautiful tan Nappa leather seats, synthetic suede trims and special embossing on the front headrests.

Surprisingly, the dashboard is still headlined by the older 8.0-inch touchscreen multimedia system. There's also the traditional gear-shifter and buttons/dials to deal with. All of which manage to nod to its long history while starting to feel like relics for such a special edition.

Overall, its pleasant and handsome but don't expect to be wowed, Mazda hasn't broken new ground with this one.

This is really a four-seater car. While there is good legroom in the rear, the falling roofline, small door aperture and huge transmission tunnel box you in a bit, almost rendering the middle seat useless for all but the shortest of folks. You do get your own air vents, though, which is generous.

The low roof also means limited headroom, made a little worse by the standard sunroof. I had room but taller people might brush the headlining. There are two cupholders front and rear for a total of four and each door has a bottle holder.

The boot is a modest-for-this-size 406 litres, rising to 1114 litres with the seats down. Access to the boot is good if not spectacular; the hatch opens wide but a slightly narrow aperture means loading and stowing flat packs and things like that could be a struggle.

The interior is comfortable and well-proportioned but front passengers will enjoy the most room. You'll still feel like you'll be jostling for premium armrest position, though!

Up front, the individual storage is adequate and the open utility tray is large but my phone slid around in it, making it hard to use the wireless charging pad.

There are enough charging options throughout the car to satisfy four people, with two USB-A ports in each row. Curiously, you can only utilise the backseat USBs when the armrest is down, which makes this feel more suited to a smaller family.

The 8.0-inch touchscreen is small and the graphics aren't super clear. You can use it as a touchscreen or opt for the rotary dial but I found switching between the two awkward. Especially, since the touchscreen is disabled while using the (wireless) Apple CarPlay or (wired) Android Auto.

The back seat is quite lean when it comes to amenities and storage. Although, the heated outboard seats are a nice touch, but again, you can only access the controls when the armrest is down.

You can fit up to three (skinny) child seats but with the low roofline, you might not want to be bending over to buckle them in.  The door apertures are not too wide either but my six-year-old had no trouble climbing in and out.

For this class, the boot is an okay size at 506L. There is a temporary spare wheel under the level loading space and it's great how the cargo-blind lifts up and away from the space because it's attached to the boot lid.

Unfortunately, this doesn't come with a powered tailgate and I did miss having that feature this week.

As the name suggests, this is a special edition and it bumps the Atenza from its usual 'top spot' in the model line-up. Yet, for a top-model it is spectacularly well-priced at $54,935, before on-road costs.

That places it below the Volkswagen Passat 162TSI Elegance ($57,190) and above the Skoda Octavia RS 180TSI ($53,090) wagons.

You get all of the features of the Atenza, like the luxurious heated and ventilated front seats, heated rear outboard seats, heated steering wheel and a sunroof.

Then, you'll also be enjoying the 20th Anniversary badging on the exterior, tan Nappa leather seats with that same badging embossed on the headrests and a delightful synthetic suede trim on the dashboard.

Other features include some nice tech, like wireless Apple CarPlay and wired Android Auto, dual-zone climate control and a premium Bose sound system with 11 speakers, but more on tech below.

Under the GT-Line's bonnet is Kia's Theta II 2.0-litre four-cylinder turbocharged engine. It's the same as before, with a stout 182kW and 353Nm. Driving the rear wheels is an eight-speed automatic from the Hyundai-Kia empire.

It's pretty rapid, knocking out the 0-100km/h spring in just six seconds, a mere 1.1 seconds slower than its faster sibling's 4.9 for the benchmark.

This shares the same engine with the Atenza and that's a 2.5-litre, four-cylinder turbo-petrol one. It has a max power output of 173kW and 420Nm of torque. Plenty of oomph to get you (and your gear) to where you need to go.

The 20th Anniversary edition is a front-wheel-drive and has a six-speed auto transmission. It's not the smoothest combination at lower speeds but let it stretch its legs and you'll be happy with the results.

Kia's claimed combined cycle figure is 8.8L/100km. As the Stinger goes without trickery like stop-start or mild hybridness, it's no surprise that my week with it yielded an indicated 10.4L/100km, which isn't bad for a 1750kg sports sedan that was not molly-coddled and also spent some time in a resurgent case of crap traffic in Sydney.

It also drinks standard unleaded, which is a nice touch.

Let's talk about efficiency. It has a combined cycle fuel figure of 7.6L/100km but I only managed to achieve 10.9L. I reckon that's pretty thirsty considering how much open-road driving I did this week but it's not outrageous for a turbo. Expect a higher figure in an urban setting.

Based on the combined figure, you should be able to get a driving range of around 816km, which is perfectly respectable for those wanting to do a road trip.

I have driven and loved the Stinger GT. It's tremendous fun, goes like a rat running away from a cut snake, which itself is being chased by a mongoose with its bottom on fire, and it handles like a proper sports sedan.

The GT-Line is obviously not that quick, but it's not slow, either. But it does take a bit of the GT's DNA and delivers a driving experience eerily reminiscent of an E90 BMW 3 Series. That seems like an out-of-date reference, but it was a beautiful car to drive with a lovely balance of ride and handling.

The steering has good feel and you know what's going on underneath the front wheels. You sit towards the centre of the car, also a BMW trademark. Turn the wheel and the car goes with you, despite its bulk, and it's happy to dance a bit with its limited-slip diff.

The 2.0-litre turbo does a good job in most conditions but you feel it coming up short when you're hustling it. It's never breathless, but the torque deficit to the turbo six is clear. If you've not driven the faster Stinger, you may not notice, but there's a touch of lag in the 2.0 that contributes to the idea it's working hard to move the big sedan.

But back off a little and it becomes a fluid, fun drive. In town it's firm but very comfortable, gently bumping rather than crashing into potholes. The rear suspension is a complicated five-link set-up that costs money and eats into boot space but delivers the goods.

Given its length the Stinger is a bit tough to manoeuvre in tight spaces and its 11.2m turning circle isn't too flash either, but you soon get used to it.

This is a car that knows what it is and stays in its lane. It's not trying to be the best but it certainly comes close with how it handles itself.

The lower centre of gravity and responsive steering make it hug corners and the car feels firmly situated on the road.

There's enough power that this is a comfy open-roader and you're confident overtaking or getting up to speed but you do feel like you're starting to dig when you hit steeper slopes.

The suspension is a little firm but your backseat passengers will feel that more than you will. Still, it absorbs enough of the bumps that you feel cushioned, even on rough country roads!

The cabin space is fairly quiet but you will get wind noise at higher speeds. Otherwise, all passengers should be able to chat without raising their voices.

I didn't find this to be a bother to park but the 360-degree view camera is terrible. It's very blurry and on the 8.0-inch screen, the image looks small, too.

That said, I love the 11m turning circle and the front and rear parking sensors. Overall, you won't have much trouble parking this one.

Safety is important on any car, but more so on a family one. I'm happy this has the usual specs, like daytime running lights, lane keeping aid, lane departure alert, blind-spot monitoring, rear cross-traffic alert, 360-degree view camera, front and rear parking sensors and intelligent seatbelt reminders.

I like the fact the adaptive cruise control now has a stop and go function and that traffic sign recognition and a head-up display are included.

The autonomous emergency braking (and forward collision warning) with car, pedestrian and cyclist detection, is operational from 10–80km/h (a little slower than the average 5.0km/h).

It has a maximum five-star ANCAP safety rating but it was done a while ago in 2018. It only has six airbags which is a bit low for a family vehicle now but that does include curtain airbags covering both rows.

There are ISOFIX child seat mounts on the outboard rear seats and three top-tether anchor points across the back. You may get lucky with three skinny child seats but two will fit best.

A 0-4 rearward facing child seat can be installed but will encroach on front passenger comfort, especially if they're tall.

Kia's ground-breaking seven year/unlimited kilometre warranty along with roadside assist for the first 12 months. Each time you service your car at Kia, you get an extension on your roadside assist for up to eight years.

Perhaps the only thing that makes you go, "Oh, what?" about the Stinger is the 12 months (Good)/10,000km (Oh...) service intervals. That's pretty common with Kia's turbo engines but is a little inconvenient. Then there's the cost - prices range from $312 to $685, which adds up to $3459 over the first seven services. If you stay under 10,000km/year, that's not bad going at under $500 per year for servicing, but if you're a high-miler, it will add up.

The servicing isn't outrageous - and the prices are capped - but it's not cheap, either.

The ongoing costs match the purchase price for their affordability. This has a five-year/unlimited km warranty, which is pretty normal for this class.

However, on the five-year servicing plan, services average $501 per service - which is very competitive for this class! Servicing intervals are also reasonable at every 12 months or 15,000km, whichever occurs first.

You're not even getting hit with the fuel pricing you can see on other mid-range models because this accepts a minimum of 91 RON petrol and is even E10 suitable.
