Family car review: 2025 Kia Carnival 1.6-litre Petrol Hybrid

How big is the boot of the 2025 Kia Carnival Hybrid?

The 2025 Kia Carnival GT-Line Hybrid's boot is epic! It is very practical for family use, whether you use all eight seats or just the first two rows.

When using five seats, the third-row seats fold down into the floor. It's a bit lumpy for an emergency nappy change, so put a change mat down first! There are great storage shelves in the boot wall, too. I found we left the wipes and first aid kit for the endless supply of band-aids in these!

When using five seats the boot will hold 24 shopping bags. That is comparable to the Kia EV9 which holds 19, the Hyundai Palisade which holds 21 and the Hyundai Staria which also holds 24.

When using two rows of seats, the Thule Sleek, future-proof, multi-configuration pram with a single seat…

…will fit in the 2025 Kia Carnival GT-Line Hybrid boot with 16 shopping bags.

The Thule Sleek, future-proof, multi-configuration pram with two sibling seats…

…fits in the boot of the 2025 Kia Carnival GT-Line Hybrid with 20 shopping bags.

The 2025 Kia Carnival GT-Line Hybrid boot can also accommodate two 90L, two 70L and two 40L Thule Chasm duffle bags.

When using five seats, the 2025 Kia Carnival GT-Line Hybrid's boot can accommodate a large dog.

The boot space is very practical for family camping trips as well.

When using all three rows of seats in the 2025 Kia Carnival GT-Line Hybrid, the boot is really deep and dips right down like a trough. It will hold 10 shopping bags, which is comparable to the Kia EV9, which will hold nine, the Hyundai Palisade, which will hold eight, and the Hyundai Staria, which will hold 16.

The Thule Sleek, future-proof, multi-configuration pram with a single seat…

…will fit in the boot of the 2025 Kia Carnival GT-Line Hybrid when using all three rows of seats with five shopping bags.

Or folded down with six shopping bags.

Also the 2025 Kia Carnival GT-Line Hybrid boot can also accommodate two 90L and two 70L Thule Chasm duffle bags.

Or you can fit a small or medium size dog in the boot of the Kia Carnival.

How good is storage in the 2025 Kia Carnival Hybrid?

There is ample family storage in front of the 2025 Kia Carnival 1.6-litre Petrol Hybrid.

The central console has two practical-size cup holders that will hold a reusable or disposable coffee cup. In front of them are two phone charging trays. There are also USB-C sockets and a 12V outlet for charging.

The central console box is a practical size for family use.

The large glove box will easily hold a wallet and iPad with the manual.

The front door bins are large and hold a refillable water bottle, iPad, and wallet. There are also storage wells in the door handles.

The second-row passengers have so much storage in the back! In the back of the central console box, there are two cup holders and a slot between them for a phone. There is also a 12V socket here.

… and on the side of the front seats are USB-C sockets for rear passengers to charge their devices.

There is a bottle holder in the rear doors, and the central seat back folds down to create a table. It also has two cup holders that will hold a reusable or disposable coffee cup, and a kids' drink cup fits in them. There are also two phone storage slots between them. 

On the back of both front seats are double map pockets that will hold an iPad but not conceal it, as well as a bag hook.

Third-row passengers have double cup holders on both sides, each holding a reusable or disposable coffee cup or drink bottle and a phone holder. There are also USB-C sockets for charging devices.

How noisy is the 2025 Kia Carnival Hybrid, and how easy is the media screen to use?

The 2025 Kia Carnival GT-Line Hybrid is not a particularly noisy car to drive.

The 2025 Kia Carnival Hybrid has a new 12.3-inch media screen and 12.3-inch driver display that wrap around the driver's side of the dash.

The media system has the new minimal system, as seen in the Kia Sorento and Kia EV9, with the introduction of Valet Mode, voice commands, weather, SOS button, and stolen vehicle assistance, to name a few. You can customise the arrangement of the icons in the media system so the ones you use most regularly are easy to access when driving.

You have Apple CarPlay and Android Auto so you can easily access your phone's navigation, listening and messaging apps etc while driving.

The reversing cameras are excellent in the 2025 Kia Carnival GT-Line Hybrid, with multiple views to choose from…

… and a digital rearview mirror, too.

The 2025 Kia Carnival GT-Line Hybrid's indicator sound is not too loud, so it did not disturb my kids while they were sleeping in the back.

The windows and doors in the Carnival are not too loud or noisy to open and close, and they do not baby-wake! The boot opens and closes with a small beeping sound that isn't too intrusive and the sliding doors open and close quite quietly too.

Becoming a parent I soon realised there are some noises and sounds I feel are unnecessary and I could happily live without if it meant my baby stayed asleep!!

That often the distraction of my screaming, distressed baby is more dangerous when driving than not having a lane departure warning for example.

If it is the lane departure warning beeping that creates distress with my baby then which is safest?

It’s where I think we need to be able to strike a balance and choose when we can mute the warnings or swap them to a vibration in the steering wheel or flashing light perhaps?

A lot of these noises come with the increase in technology and especially linked to safety features and alerts. For me these all have their place.

Another thing I have realised is I spend my time in a lot more places where small children roam, parks, beaches, play gyms, swimming lessons, daycare centre etc. I have become more aware that when I’m reversing or manouvering in the car parks I have to tripple check for small children running around behind me or being in my blind spot when reversing. For this I LOVE reversing cameras, I just don’t like their beeping sounds!!

I have become so much more aware of safety and potential accidents or hazards since having a child and so I love the peace of mind that I get from the cameras and sensors combined with my own vision from windows and mirrors as I don’t trust cameras alone.

The Hybrid Carnival is a quiet and smooth drive, and there are no real baby-waking noises. When the hybrid motor switches over to the engine, it is not a startling transition. It does so smoothly.

How many child/baby seats can you fit in the 2025 Kia Carnival Hybrid?

When it comes to installing child seats in the 2025 Kia Carnival Hybrid, there are ISOFix points in both outer second-row seats. They are not within plastic guides but easy to connect to.

All three second-row seatbacks have top tether anchorages right down at the bottom. These anchorages are clearly labelled but not within plastic guides and are easily located through the boot or by bringing the seats forward. You may need an extension strap for rear-facing child seats to reach the anchorages.

Three child seats fit well across the second row of the 2025 Kia Carnival Hybrid. Combinations of forward-facing and rear-facing child seats also fit well.

In the 2025 Kia Carnival Hybrid, both outer third-row seats have ISOFix. They are not within plastic guides but easy to connect.

There are top tether anchorages on the back of both third-row seats, down at the bottom, not within plastic guides, but they are clearly labelled and easy to connect to. There are lots of bag hooks and handles on the back of the third-row seats, so you have to look below those to the top tether anchorages! 

Two child seats fit comfortably in the outer third-row seats, and I could fit between them.

Accessing the third-row seats is good in the 2025 Kia Carnival 1.6-litre Hybrid. The second-row seats are all individual seats, so many families remove the central second-row seat and create a walk-through to the third-row.

Or you can move one of the outer second-row seats forward, giving you a little space to climb through to the third row.

The Kia Carnival has very good legroom. The second-row seats are all individual, so you can slide them backwards and forwards to distribute the space however your family needs to.

The footwells are flat throughout the 2025 Kia Carnival 1.6-litre Hybrid, providing great legroom for all rear passengers and allowing everyone to get to and from their seats more easily and have good kick room.

With a forward-facing child seat in the third row and a rear-facing infant capsule in the second row, we could fit a 180cm driver in front.

Legroom can also be adapted by the driver bringing the front passenger seat forward or backward and changing the recline using the controls on the driver's side. These are particularly helpful when kids are getting in and out at pick-up and drop-off time from the kerb side of the vehicle and also when you have an elderly relative in the front passenger seat. Or your kids have great fun fiddling with them from the back while you are sitting in the ‘Ejector seat!'

How comfortable is the 2025 Kia Carnival Hybrid?

All rear passengers are kept comfortable with air conditioning vents in the ceiling in both rear rows…

…that you can control from the front dash and media screen climate controls.

Both rows of rear passengers also have built-in window blinds in the top-spec GT-Line 2025 Kia Carnival Hybrid. These keep little passengers shaded from the sun while driving and save you from having to buy aftermarket versions.

There are lights in the ceiling for both rows of rear passengers and a handle above the rear doors so you can hang a toy from them for little rear-facing passengers to keep them entertained on long journeys.

The second-row seats are comfortable for passengers not in child seats, with good legroom and a flat floor.

The third-row seats are also comfortable for teen and adult passengers and have good head and legroom.

The upholstery in this top-spec 2025 Carnival GT-Line Hybrid is grey pleather with perforated central panels and beige door panels and ceiling. I like the combination of the two colours because the grey on the seat parts will hopefully not show the marks and dirt of family life as quickly as all cream leather does. However, the beige door panels and ceiling give brightness to the interior. The front seats are equally as comfortable as the rear seats in the Kia Carnival Hybrid.

There are four air-conditioning vents across the front of the dashboard, two below the media screen and one at each end of the dashboard.

Visibility in the 2025 Kia Carnival GT-Line Hybrid is impressive, even with five child seats onboard! The rear windscreen allows you to see a surprising amount.

Excellent rear-viewing cameras in the Kia Carnival really help with visibility. There is also a 360-degree exterior camera, which makes manoeuvring and parking easier.

One thing I have noticed since being a mum is I hate it when I reach a destination or get home from being out and Bub has either done really well in the car or she is screaming her head off and I have done really well to keep it together for the entire journey (usually the latter!!) and it takes 10 minutes to park the car! It can be really stressful. Usually, I dread parking in our tight apartment block carpark, but the Kia Carnival is easy to reverse park!

The Kia Carnival also has a digital rear-view mirror, allowing you to see out of the back if you can't see past your child seats.

How safe is the 2025 Kia Carnival Hybrid?

The petrol and diesel variant Kia Carnivals, on sale from Jan 2021 onwards, have a 5-star ANCAP safety rating, scoring 90% for adult occupancy and 88% for child occupancy in crash testing. However this Hybrid variant has not been assessed and is unrated.

Of the child occupancy testing for the petrol and diesel variants, ANCAP wrote:

In the frontal offset and side impact tests, protection of the 10 year and 6 year dummies was GOOD for all critical body regions and maximum points were scored.

The Kia Carnival is fitted with lower ISOFix anchorages and top tether anchorages for all seating positions in the second row and outboard seats in the third row. Top tether anchorages and ISOFix anchorages are not available in the centre seating position in the third row. Installation of child restraints in the third row centre position is therefore not recommended.

Installation of typical child restraints available in Australia and New Zealand showed most child restraints could be accommodated in most rear seating positions, however one of the selected Type A convertible seats could not be correctly installed in rearward-facing mode using the ISOfix anchorages in the outboard seats of the second and third rows. Care is also required when installing one of the forward-facing convertible seat using the ISOfix anchorages in the third row positions.

Seven airbags are standard on all models built before February 2024. All Kia Carnivals built after February 2024 have eight airbags as standard:

Dual frontal, side head-protecting airbags (first, second & third rows), and side chest-protecting airbags (first row), and a driver knee airbag are standard. A centre airbag which provides added protection to front seat occupants in side impact crashes is standard after Feb 2024.

The 2025 Kia Carnival GT-Line Hybrid comes with adaptive cruise control (ACC), anti-lock braking system (ABS), autonomous emergency braking (AEB) – Car-to-Car / VRU /Backover, automatic emergency call (eCall), blind spot monitor (BSM), child presence alert, electronic brakeforce distribution (EBD), electronic stability control (ESC), emergency brake assist (EBA), fatigue reminder, fatigue monitor/detection, forward collision warning (FCW), lane departure warning (LDW), lane keep assist (LKA), rear cross-traffic alert (RCTA), reversing collision avoidance (camera), secondary / multi-collision brake, speed assistance – auto / intelligent speed limiter/manual speed limiter/speed sign recognition & warning as standard.

Some of these safety features are also features that drive me crazy as a mum! Like the lane departure and forward collision alert or the parking sensor beeping sound. I want all the safety technology AND to be able to mute the sound when Bub’s asleep!
