Kia Sorento vs Mazda CX-30

What's the difference?

The Kia Sorento S diesel AWD is a solid buy option in the lower-spec realm of the market. This AWD SUV is not spectacular but it manages to be competitive and, as a seven-seater with updated technology and some good features, it does have ample potential as a daily-driving family mover.

However, if you want more safety tech and more premium accoutrements, you’re likely better off forking out the extra $10,000 or so and getting a top-spec Sorento GT-Line instead.

About to enter its fifth year in market the Mazda CX-30 is holding up well and this GT SP FWD grade delivers solid value relative to its key competitors, of which there are many. It’s also space-efficient, practical and performs well with top-shelf safety, decent refinement and good dynamic ability.

Alternately, it’s crying out for a hybrid powertrain to improve fuel efficiency, the interior form and function is starting to date and while it meets the market the ownership promise could be sharper. But this little SUV is still worthy of a spot on your new-car short list.

The Sorento’s exterior is stunningly inoffensive. So, for anyone looking for an SUV that won’t make passers-by dry retch that’s all boxes ticked, I reckon.

The cabin feels family-friendly and functional. It's a basic but well designed space, although there’s no getting past the fact this is at the cheaper end of the Sorento line-up as its cloth seats and expanses of hard plastic remind you.

That said, chrome-like touches and faux hand-stitching go some way towards balancing out that impression.

The low-slung dashboard with integrated 12.3-inch touchscreen dominates the front of the cabin in a good way.

Mazda continues to follow a disciplined design path with everything from the MX-5 sports car to the BT-50 dual-cab ute sharing key attributes like the brand’s signature trapezoidal grille, simple flowing lines and sleek head- and tail-lights, all wrapped up with a subtle hint of chrome here and there.

Car-spotters with the GT SP on their checklist should look out for 18-inch black metallic rims as well as black exterior trim, including the mirror caps. 

Inside, the CX-30 maintains Mazda’s restrained approach with smooth surfaces integrated across the multi-layer dash and primo leather-trimmed seats.

That said, this car is starting to show its age with the multimedia screen plonked on the top of the dash (in typical Mazda fashion) and a largely conventional instrument cluster.

Yes, the main dial is configurable courtesy of a central 7.0-inch TFT screen, but next to more recent arrivals boasting sleek, often twinned, flat screen displays the CX-30 looks and feels out of touch. 

Functionally, there’s a sensible mix of digital controls and physical buttons (points for audio volume and ventilation dials!), but… the multimedia screen can only be accessed by a rotary controller in the centre console once the car is mobile (it works as a touchscreen when you’re stationary).

Some say touchscreens take your eyes off the road so the controller makes sense, but with a sequential app like Spotify it can take a lot of twirls to get to where you want to go, which upsets concentration and takes your eyes off the road, anyway. I’d prefer the relative ease of a quick press on a screen.

Aside from all that, the materials used are high quality with soft-touch surfaces across key contact points and hard plastics confined to high-wear areas. 

This Sorento is 4815mm long (with a 2815mm wheelbase), 1700mm high and 1900mm wide.

As mentioned earlier, the interior is quite basic and simply designed, but with a low-key classiness about it. 

The driver’s seat is six-way manually-adjustable with a pump-action for height, so pin-pointing your preferred position is a welcome minor workout unto itself.

The front seats are adequately comfortable without being too plush – that’s fine with me – and from there driver and passenger have ready access to plenty of storage and cupholders (including two in the front, four in the second row and two in the rear seat) and charging options (including two USB charge points in the front console and one 12V power outlet behind the centre console and one in the cargo area).

My teenagers weren’t impressed at all with the fact they had to plug their smartphones into charge points at the front. Oh, the torture!

The 12.3-inch digital multimedia system has Apple CarPlay and Android Auto, both wired or wireless, and it’s an easy-to-use set-up with a crisp screen.

Air-con is a manual-controls affair, second-row passengers get air vents only (on the rear of the centre console), and third-row passengers don’t get vents or fan controls.

The second row is reasonably comfortable with room enough for head, shoulders and legs to be on the right side of comfy.

It sports a bottle holder in each of the doors, and there’s a centre armrest in the second row with cupholders for the El Grande cups of whatever almond-infused crappuccino your obnoxious screenagers are currently addicted to. 

The second row is in a 60/40 configuration, which slides, reclines and folds down flat.

The third row is in a 50/50 configuration, a split-fold flat set-up, and it's the realm of mini humans – or you could put adults back there for any trip lasting longer than 10 minutes and you’ll be hated for life.

For those interested in packing potential space, the rear cargo area offers a listed 179 litres of storage capacity; a listed 608 litres in the rear cargo area when the third row is folded away; and 1996 litres when the second and third rows are packed away.

At just under 4.4m long, close to 1.8m wide and little over 1.5m tall (with a 2655mm wheelbase) the CX-30 is in the middle of the pack it competes with in terms of key dimensions.

And space up front is more than adequate, with an impressive feeling of roominess for a relatively small SUV.

For storage, there’s a large lidded box (which doubles as an armrest) between the front seats as well as a pair of cupholders in front of the gear-shifter with a bay for wireless device charging ahead of that.

The glove box is big, there are bins in the doors with room for decent size bottles and a drop-down tray for sunglasses sits overhead.

Move to the rear and the amount of space on offer is surprisingly generous. Sitting behind the driver’s seat, set for my 183cm position, I have plenty of head and legroom, although three full-size adults across the back seat will be an uncomfortable proposition for anything other than short trips. A trio of up to mid-teenage kids will be fine.

Adjustable air vents at the back of the front centre console are a welcome inclusion for back-seaters and storage runs to a map pocket (weirdly, on the back of the front seat only), a pair of cupholders in the fold-down centre armrest and bins in the doors with room for smaller bottles.

In-cabin power and connectivity includes two USB-C outlets and a 12-volt socket in the front centre storage box. No USBs specifically for those in the rear, which is a miss for road trips and no 12V in the boot which can be handy when camping or picnicking.  

Speaking of the boot, cargo volume with the rear seat upright is okay for the class at 317 litres, which expands to a healthy 1479L with the 60/40 split-folding backrest lowered. For comparison the Kia Seltos coughs up 433L with the rear seat upright.

The space is illuminated, there are tie-down anchors to help secure loose loads and there’s a space-saver spare sitting under the floor.

And if you’re keen on towing a tinnie or similar you’re good to go for a 1200kg braked trailer (600kg unbraked).

The Mazda CX-30 G25 GT SP FWD weighs in at $43,140, before on-road costs and our test example features the optional ‘Vision Pack’, the details of which we’ll get to shortly, raising the price $1300 to $44,440. 

Alternate options around that price point include the Hyundai Kona Premium N Line 2WD ($42,500), Kia Seltos GT-Line FWD ($41,850), Mitsubishi Eclipse Cross Exceed 2WD ($40,990), Honda HR-V e:HEV L 2WD ($42,900, drive-away), Nissan Qashqai ST-L FWD ($42,690), Peugeot 2008 GT FWD ($44,490), Renault Arkana Techno FWD ($41,000), Suzuki S-Cross Plus FWD ($41,490), Toyota C-HR 2WD GXL Hybrid ($42,990) and Volkswagen T-Roc Style FWD ($40,590).

That’s quite the automotive smorgasbord, the resulting price and specification cage fight meaning every included feature counts and the Mazda heads into battle with some significant weapons in hand.

Specifically, dual-zone climate control, a head-up display, a 10.25-inch ‘widescreen’ multimedia display, 7.0-inch driver’s multi-information display, 12-speaker Bose audio (with digital radio), wireless Android Auto and Apple CarPlay, ‘Burgundy’ leather seat trim, heated front seats, leather trim on the gearshift and heated steering wheel, wireless phone charging, power-adjustable driver’s seat (with memories), a glass power tilt and slide sunroof and a power tailgate.   

There’s also adaptive auto LED headlights, 18-inch black metallic alloy wheels, radar cruise control (with stop/go), a reversing camera, auto-fold (and tilt) heated exterior mirrors and keyless entry and start. 

It’s an impressive and competitive equipment list for a small SUV under $45K, even before we get to the performance and safety tech covered later in the review.

This Sorento has a 2.2-litre, four-cylinder common-rail diesel engine, producing 148kW at 3800rpm and 440Nm at 1750-2750rpm and that’s matched to an eight-speed dual-clutch auto transmission.

This is a generally clever and effective combination, but there is noticeable lag to acceleration from a standing start, no matter how hard you stomp the right foot.

It has all-wheel drive (part-time with lock mode) and driving modes that include on- and off-road options.

The CX-30 GT SP is powered by a 2.5-litre, naturally aspirated, four-cylinder petrol engine producing maximum power of 139kW at 6000rpm and peak torque of 252Nm at 4000rpm.

It’s a proven all-alloy unit featuring direct-injection as well as variable intake and exhaust valve timing with drive going to the front wheels via a six-speed auto transmission. 

The AWD version of the GT SP adds an electromagnetic multi-plate clutch pack (managed by a multitude of sensors) to selectively engage the rear wheels, as well. But its engine and transmission combination is identical to this FWD model’s.

Official fuel consumption for the 2.8-litre four-cylinder Sorento S diesel is 6.0L/100km on a combined cycle. 

Actual fuel consumption on this test, from pump to pump, was 6.6L/100km. 

This Sorento has a 67-litre fuel tank so – going by that fuel consumption figure – you should be able to get a driving range of about 1015km from a full tank.

The CX-30 GT SP FWD’s official fuel consumption figure on the combined (urban/extra-urban) cycle is 6.6L/100km, the 2.5-litre atmo four-cylinder engine emitting 154g/km of C02 in the process.

It features fuel-saving stop-start and cylinder deactivation functions as standard and over a combination of city, suburban and some freeway running we saw an average of 8.4L/100km, which is average for an SUV in this class. A comparable hybrid package would easily better this result.

Based on the car’s 51-litre fuel tank theoretical range between refills is 772km, which drops to just over 600km using our real-world test consumption number. But the good news is this CX-30 runs happily on cheaper 91 RON ‘standard’ fuel.

As I mentioned earlier, this SUV can feel a tad lardy at times, especially from take-off, but it exhibits slightly livelier characteristics soon enough. Just don’t climb into the driver’s seat expecting a dynamic experience.

Steering has a nice balance to it and the Sorento never feels gargantuan so navigating through busy city and suburban streets is on the correct side of easy.

Ride is a bit firm, but the all-pervasive mindful peace you experience from being in such a hushed cabin tends to mostly negate any minor discomfort you may otherwise feel from clipping every lump and bump on the road.

On-road driving modes are 'Comfort', 'Sport', 'Eco' and 'Smart' and off-road modes are 'Sand', 'Mud' and 'Snow'. All of these adjust engine outputs, throttle control and transmission behaviour to best suit the terrain and driving conditions.

Niggle: The driver-assist tech is a bit abrupt and intrusive. I’ve found this to be the case in Hyundai SUVs, too.

The traffic sign recognition, in particular, is clunky, reacting to signs that don't apply at that time of day, for example school signs, or it reacts to signs that don't actually apply to that section of road. So it's regularly chopping and changing between what speeds you should be at and what speeds you shouldn't. 

This Sorento is an AWD with 176mm of ground clearance so I tested it on muddy grass, firm sand and gravel tracks. Nothing outrageous, but mildly challenging enough to make sure the all-wheel drive system can do what’s expected. And it does, seamlessly.

These off-road drive modes are, of course, no substitute for 4WD, but they are fine for when conditions become a little bit slippery. For example, if there’s been a drizzle of rain on the bitumen or the dirt track becomes a bit muddy.

This Sorento has a maximum towing capacity of 750kg (unbraked trailer) and 2000kg (braked).

It’s rare in 2024 to find a small SUV that doesn’t have at least one turbocharger attached to its engine, the CX-30’s 2.5-litre ‘atmo’ four being one of those increasingly scarce examples.

But Mazda’s been laser-focused on extracting maximum power and efficiency from its non-turbo petrol engines for yonks and this one stands up well.

It doesn’t have the low-down punch a turbo typically delivers but maximum pulling power arrives at a useable 4000rpm and it’s eager enough for easy city and suburban running as well as confident freeway cruising.

Although Mazda doesn’t quote an official number you can expect a sprint from 0-100km/h in around 8.5 seconds, which is quick for the class.

Worth noting engine noise and a raspy exhaust note make their presence felt under acceleration and the throttle isn’t as refined as it could be. Not a huge deal, but a slight jerkiness is evident on initial, especially moderate, acceleration.

The six-speed auto is smooth and fuss-free, the steering wheel paddle shifters on hand if you need to intervene and select a specific ratio. ‘Sport’ mode peps things up, causing the transmission to shift down earlier and up later. But it’s aggressive in that it often holds onto a gear for too long and you find yourself diving back to the default normal setting.

Tipping the scales at just under 1.5 tonnes, the CX-30 is underpinned by a MacPherson strut front, torsion beam rear suspension and ride comfort on typically pock-marked urban surfaces is average for the category. That is, a bit jittery over bumps and corrugations but there’s no bone-jarring going on here.

Steering feel and response is good and the grippy steering wheel helps with a connection to the front tyres. Speaking of which, the standard rubber is high-performance (215/55) Dunlop SP Sport Maxx 050 which is  grippy and commendably quiet. 

Push on into a corner and the CX-30 remains balanced and predictable with body roll well under control. Torque vectoring, by engine and physical braking, is also onboard to reel things in if you overstep the mark.

Braking is by discs all around, vented at the front and solid at the rear, and they wash off speed effectively with a satisfyingly progressive pedal action.

Vision is good, which combined with the CX-30’s compact dimensions and 10.6m turning circle, means parking is easy. Especially when you factor in the hi-res reversing camera and front and rear parking sensors. 

The CX-30 carries a maximum five-star ANCAP assessment from early 2020 when the car was introduced locally.

It scored a stunning 99 per cent in the adult occupant protection category and an impressive 88 per cent for child occupant protection.

Active (crash-avoidance) tech includes AEB (operating from 4.0-160km/h) as well as lane keep assist, lane departure warning, traffic sign recognition, intelligent speed assistance, blind-spot monitoring, front and rear parking sensors, rear cross-traffic alert, a reversing camera and tyre pressure monitoring.

Mazda’s ‘Vision Pack’ is also standard which includes a 360-degree camera view, ‘Cruising & Traffic Support’, driver fatigue monitoring and front cross-traffic alert.

The airbag count runs to seven - dual front and front side, full-length side curtains and driver’s knee.

There are three top tether points for child seats across the second row with ISOFIX anchors on the two outer positions.

A seven-year/unlimited km warranty applies to the Sorento line-up.

Servicing intervals are scheduled for every 12 months or 15,000km, whichever occurs soonest.

Capped-price servicing covers seven-years/105,000km and at the time of writing ranges between a low of $370 and a high of $817 per service over that period. Total cost is $3787 for an annual average of $541, which isn't particularly cheap.

Mazda covers the CX-30 with a five-year/unlimited km warranty which is the norm in the mainstream market, and it’s worth noting a growing number of competitors are now at six, seven or even 10 years, although the latter are typically conditional on authorised dealer servicing. Roadside assistance is provided for the duration of the warranty.

Service is recommended every 12 months or 15,000km and Mazda’s ‘Service Select’ program sets maintenance pricing out to seven years, the lowest over that period being $352 and the highest $626, for an annual average of $459, which is reasonable but not exceptional for the category.

For comparison, a similarly specified Toyota C-HR averages $330 per workshop visit over the same period.
