Mazda CX-5 vs Kia Stonic

What's the difference?

The Mazda CX-5 Akera G35 offers small families a great host of premium features, as well as solid power and handling – all in an attractive package. But the emphasis here is on ‘small’ families because it’s on the compact side for a mid-sized SUV and its rivals offer more back seat space.

Its ongoing costs are reasonable and I enjoy driving it, so it gets a 7.6/10 from me.

My son calls out the back seat as a bit squishy but he otherwise likes it. He gives it a 7.0/10

Once over the little thrill of driving a car we weren't supposed to get (okay, it wasn't that thrilling), a few things became clear. You can now buy a compact SUV with a good long warranty, a bit of Kia flair and a roomy cabin, at least for its size.

It drives really well even if the transmission was a bit reluctant to do what I wanted. It's easy to park and will live very happily in the city while carrying reasonable numbers of people and their things. It may not be as bang up to date as some of its competitors, and the GT-Line's value is borderline, but it delivers plenty in its small package to a rapacious SUV market.

The Mazda CX-5 hasn’t seen much change to the exterior other than a more horizontally-styled grille. It’s a medium SUV with a handsome kerb-side presence thanks to its full-suite of LED lights and 19-inch alloy wheels. It’s an inoffensive design that should appeal to a wide audience.

The interior looks premium with the brown Nappa leather upholstery and black leather trims. The plethora of soft-touchpoints throughout reinforces that the Akera is the top model.

There's one thing I really like about Mazda and that's how it manages to balance the traditional with the new. The cabin is a seamless blend of the two elements.

The instrument panel features a 7.0-inch digital display but still has analogue dials. There's a 10.25-inch multimedia system on the dash but still a bunch of control buttons and dials to press. The gear shifter is coupled with an electric brake, the sunroof is coupled with a manual blind. You get it.

This duology between high-end tech and traditional elements makes the interior feel up to date but very accessible.

The Stonic clearly looks like it is related to the Rio, but also bears a strong resemblance to the Seltos. Underneath is the very familiar small hatch Rio but Kia says every panel is different. 

The panels might be, but have a look at the rear door and the way the glass meets the C-pillar and you can tell it's a Rio. 

Which is fine, of course, because I think the Stonic looks really good in GT-Line form, with the bigger wheels, some well-judged cladding and some nice sculpting on the body. 

If you plump for the two-tone paint job (which I think looks great), you will go without the sunroof. Also the sun-safe option, but I know some are fans of a hole in the roof.

The cabin is by-the-numbers Kia, which is to say it's well laid-out and looks good, but won't be troubling a beret-sporting art critic for superlatives. 

Unlike the exterior, it's straight out of the Rio, which does have its downsides, which we'll discuss further.

Despite sitting in the medium-SUV segment, the CX-5 is on the compact side for cabin space and front passengers benefit the most in terms of leg- and headroom.

Back rowers get a decent amount of headroom but legroom is squishy and my legs press into the back of the drivers seat when its in my driving position, and I'm only 168cm tall!

My seven-year old complained about his space and asked Dad to slide forward for more room, which is something to consider if you have gangly teenagers.

The seat comfort sits on the firmer side for both rows and the electric front seats are narrower and shorter than I like for long journeys but for the A to B trips, they’re comfy enough.

Only the driver’s seat gets powered lumbar support but they both have heat and ventilation functions.

Individual storage is average for this class with a smallish glove box and middle console that has a removable shelf. A deep utility tray, which houses the wireless charging pad and a 12-volt port, sits in front of the gearshift and there are two cupholders in the centre console.

Each door has a shallow storage bin and the front doors also get a skinny drink bottle holder.

For individual storage in the rear, you get map pockets on the rear of the front seats and two cupholders in a fold-down armrest.

The armrest also houses two USB-A ports and the heat function buttons for the outboard seats and it's because of this positioning and the narrower width of the seat, that the back row feels more suited to two, rather than three passengers.

The technology on the whole is easy enough to use but the rotary dial operation of the multimedia system is a bit annoying to access while on the go.

The wireless Apple CarPlay and Android Auto is a great feature and means one less cable to worry about but the built-in satellite navigation with 10-year map updates is a highlight. The head-up display pulls through the nav directions, too, which is always handy.

You also get two USB-C ports and another 12-volt outlet up front, so everyone should be sorted for charging.

The boot features a powered tailgate which is a handy family feature and a temporary spare tyre is located underneath the level floor.

You get 438L of storage capacity with the second row seat upright, which is plenty for my errands and grocery shop. That jumps up to 1340L (VDA) when the rear seats are folded. 

The cargo cover attaches to the lid, meaning it stays out of the way when you're loading stuff into the boot.

For a car this size, it's reasonably roomy. I can sit behind my driving position in the rear seat and while violin playing is off the agenda, it's not claustrophobic.

Front seat passengers have plenty of storage to play with, including a split storage box underneath the console for phone and wallet-chucking. 

You also get two cupholders, even with the space-robbing conventional handbrake (I like a standard handbrake, though, so I didn't mind too much).

Each front door has a pocket for a decent-sized bottle, but not so rears. And your back seat passengers won't have an armrest or cupholders, either.

Boot space is an impressive 352 litres (VDA) with the seats up and 1155 litres with the seats down, although you don't get a flat floor with the seats folded and you do have a drop to the boot floor over the loading lip. Nothing terrifying, but the more you know...

The GT-Line tops a three-spec range, starting with the base model S manual at $22,990 drive-away (add another grand for the auto).

Then it's $24,990 drive-away for the Sport (plus $1000 for the auto) and $29,990 drive-away for the GT-Line, which is auto-only and has a turbo engine. 

That's some pretty fancy footwork with the spreadsheets (which I know isn't a thing, imagine how dirty the keyboard would be).

If you've bought a GT-Line, your kebab short of thirty grand gets you 17-inch alloys, a six-speaker stereo, climate control, a reversing camera, keyless entry and start, rear parking sensors, cruise control, sat nav, auto LED headlights with auto high beam, auto wipers, fake leather bits and pieces, powered and heated folding mirrors, a sunroof and a space-saver spare.

The larger 8.0-inch media screen hosts Kia's updated and very excellent software, with its cool and subtle graphics, fast hardware and, as expected, Apple CarPlay and Android Auto.

The speakers are a bit tinny, but as long as you don't turn them up too much, you'll be fine. Handily, CarPlay is wireless and you can have two phones connected at once to the Bluetooth system. Try that in a Ferrari.

The Akera is an all-wheel drive with a six-speed auto transmission and our test model has the 2.5-litre four-cylinder turbo-petrol engine that produces a maximum power output of 170kW and 420Nm of torque. The turbo ensures it never feels sluggish, even when you’re hitting hills.

The GT-Line is the only one of the three in the range to score Kia's rorty 1.0-litre, three-cylinder turbo, good for 74kW and 172Nm to haul its 1200kg weight. 

A seven-speed dual-clutch transmission drives the front wheels and you'll hit 100km/h in about 10 seconds.

The compromise for getting extra power from the turbo is fuel efficiency takes a hit.

The official combined fuel cycle figure is 8.2L/100km but my real-world usage came out at 10L/100km. That’s after mostly open-road driving this week, too, so it’s a bit thirstier than I was expecting.

Based on the combined cycle number and the 58L fuel tank, expect a driving range of around 784km – which is still great for the odd road trip.

Kia's government-mandated fuel economy testing yielded an official combined-cycle figure of 5.4L/100km. 

As I have found over the years with this engine, that's a fairly optimistic number, my week with the Stonic delivering 8.4L/100km in an almost even mix of highway and suburban running.

The Stonic has that rarest of things in a Korean car - stop-start, which helps rein in fuel usage around town. Happily, you'll be filling the 45 litre tank with standard unleaded.

The Akera turbo-petrol delivers a decent well of power to dip into and it feels peppy in most situations. Even when you’re overtaking or getting up to speed you don’t feel like you’re nearing the bottom of the power barrel.  

Steering is responsive and the car is agile when you tackle narrow car parks or streets. However, you still get some roll in corners which my passengers felt more than I did.

The cabin is quiet, even at higher speeds and the suspension is firm enough that you feel the bumps but you’re not jostled about. The ride comfort is still good.

I’ve said it before but I love parking medium SUVs because their size is so forgiving in a car park! The Akera is no different and it’s especially easy thanks to the ultra-clear 360-degree view camera system. You also get front and rear parking sensors to help out when needed. 

I must admit to being slightly puzzled by the Stonic. I've already driven the Rio GT-Line and there is one thing that is the same between the two cars and that's the seven-speed dual clutch's awkward behaviour in traffic. 

The car I had was not at all keen to respond to the movement of my right foot on the accelerator, with my wife and I developing an in-joke about having to make a verbal suggestion about which gear to choose. 

It also rolled back more than I'd like on slopes when starting from a standstill.

The other things I didn't like were the front seats. Straight out of the Rio, they are wide but not very supportive on longer trips, such as the one we took up into the Blue Mountains (a roughly 250km round trip from our home in Sydney). 

Complaints about the seats are certainly mine, but I checked in with colleague Richard Berry, who didn't have the same hesitant transmission struggle, so it could just have been a drama with the car I drove. 

The rest of the Stonic experience is really good. The 1.0-litre turbo is definitely the one to go for if you can stretch to it. The numbers don't seem big, but it's got decent punch in the gears and cheerfully climbed the Blue Mountains quietly and without hunting up and down the gears. 

Around the city it also means it's easy to thread through the traffic, with good response from low revs when the transmission is playing well.

The steering is really nice, too, with just the right weight and speed to make city-wrangling easy. The extra ride height and softer suspension also make for a very comfortable ride around town without taking away from the body control. In fact, it's quite a bit of fun.

In a typical ANCAP quirk, the GT-Line does not (yet) have a safety rating where the S and Sport carry the Rio's five star assessment from 2017. When the rules weren't as tough as they are today.

The GT-Line, as with the rest of the range, scores six airbags, ABS, stability and traction controls and a reversing camera. 

The forward AEB works with other cars between five and 180km/h while pedestrians and cyclist detection works between five and 85km/h. You also get lane keep assist and lane following assist.

The kids are looked after with three top-tether anchors and two ISOFIX points.

The CX-5 comes with a five-year/unlimited km warranty, which is average cover for the class but some of its rivals offer longer terms.

There is a five-year, or up to 75,000km capped-price servicing program and services average $423 per workshop visit, which is competitive.

Servicing intervals are reasonable at every 12 months or 15,000km, whichever occurs first.

Kia offers a seven-year/unlimited kilometre warranty, which is only shaded by Mitsubishi's caveat-filled, 10-year/200,000km warranty. 

The Stonic demands a return to the dealer ever 12 months or 10,000km, which is kind of irritating as the non-turbo models are 12 months/15,000km. 

As ever, Kia offers a capped-price servicing regime but the numbers aren't yet available on the website (yet).

Lucky for you, we've got them. Prices bounce around a bit and are as low as $283 and as high as $704 with the first seven years/seven services costing $3299, averaging out at $471 per visit. 

Over the five years, it's $260 more than the 1.4-litre but you're servicing more often if you drive more than 10,000km per year.
