BYD Sealion 6 vs Kia Carnival

What's the difference?

So, should Toyota, Tesla, Hyundai and others be worried about the arrival of the Sealion 6 and BYD’s new DMi powertrains? Yes, but not because it represents any major breakthrough in technology or dynamic prowess. 

Instead, the strength of the Sealion 6 is how average it is. It may not be the obvious class-leader in any particular area, but it does a good job in almost every measurable aspect and doesn’t possess any major flaws.

Yes, there are still questions about the long-term dependability of BYDs but that’s a risk any new owner will need to accept. But the very sharp pricing should tempt plenty of buyers to take that chance and continue BYD’s steady upwards trajectory in the Australian market.

Ok, here's the rub. Everything you just read could well be pointless. You like the Carnival. In fact, it sometimes makes up close to 90 per cent of the sales in its segment, and outsells all of its competitors combined.

So whether I like it or not, I suspect you'll be buying one anyway.

But I can say this - the new Carnival improves the formula right across the board. Well, everything except for price.

This is one area where BYD has a mixed record. Not to be unkind or create an international incident, but the Chinese car industry has a history of not being totally original with all of its automotive designs.

However, things are improving and the Sealion 6 is a good example of the Chinese industry learning to develop its own style. While there are some subtle hints from European models, overall it’s a smart-looking mid-size SUV with some character to it - rather than being a bland imitation of something else.

One area where the Sealion is a cut above its competition is its size, being longer than and wider than the RAV4, Mitsubishi Outlander and Nissan X-Trail.

Surely the greatest trick the Carnival pulls off, and it does so convincingly, is that it manages to make something so quintessentially uncool, the people-mover, and make it look good. Somehow sporty, even.

I like the Carnival's big, bold and blacked-out front end of the GT-Line, and with its two-tone 19-inch alloys, wide stance and low ride height, it looks almost like some mad attempt at a JDM tune car, rather than a sensible people mover.

Elsewhere, the boxy profile, the sharp body creases and the third-row compartment that kind of juts over the rear tyres like a house that's been extended all somehow work, and give the Carnival far more street cred than you might expect.

Inside, we spent time only in the flagship GT-Line and its GT-Line Lite sibling, and both present as calming, comfortable spaces, and Kia's minimalist approach to combining the climate and audio controls into a single strip (it's functionality can be changed by pushing a button) helps keep the cabin fuss free.

The tech in the top-spec models feels modern and on-point, too, and the materials are all nice under the touch. Be warned though, the cabin plastics get progressively worse the further back you sit, and the third row is cocooned by hard and scratchy plastics.

That external size translates to a roomy cabin, which also has some flair to the design but thankfully a bit more restrained than the smaller Atto 3 - which is a bit over-the-top in this reviewer’s opinion. 

The element that sticks out immediately is the large central touchscreen which, like other models in the range, can rotate either vertical or horizontal, depending on your preference.

I don’t understand the point of this, because when rotated vertically it impacts your forward vision and can interfere with the air conditioning vents; and I can’t even see it with my polarised sunglasses.

It simply makes more sense horizontally, but I guess all carmakers are looking for catchy gimmicks these days. But while it may seem like a cool party trick it remains somewhat confusing to me, like one more thing to go wrong. But maybe I’m just getting old and grumpy.

What I do like and think is a great idea is double smartphone charging pads in the centre console. And overall the design of the cabin feels well thought out and has plenty of useful storage areas.

The seats are fine, a little flat and the fixed headrests are irritating, but overall they’re soft and supportive enough.

The key in the second row seating is the amount of space, with the extra length of the Sealion 6 compared to its rivals showing up with more knee room in the back for families with growing teenagers or those who need to carry their adult friends.

There’s also a pair of USB ports in the back too, so everyone can keep their electronics charged.

The boot is a good size, measuring 425 litres on paper, and has a nice long and wide floor. But some of that space is thanks to the lack of a spare - so that counts against it in my book.

The Carnival measures 5115mm in length, 1995mm in width and 1775mm in height, and it rides on a sizeable 3092mm wheelbase. 

And those mini-van dimensions have a predictably positive impact on luggage space, with room growing from 627 litres with all seating rows in place, to a massive 2827 litres with the third row stowed.

The key practicality perk here, though, is space, and lots of it. At 175cm, there was ample room for me in the middle row, and you can configure the cabin to your liking, too. You can slide the row on rails, for example, to prioritise leg room where you need it, and the middle seat folds down to reveal cupholders in a kind of hard plastic travel tray.

But even in the third row I could easily get comfortable, though head room begins to get a little tighter. There are cupholders and USB connection points, too, and I can honestly say you could send full-size humans back there and not feel overly guilty about it.

The Carnival will tow 2000kgs braked, too.

Bad news first. The price is higher this time around, right across the five-trim line-up, with the prices up between around $2600 and $5300, depending on which trim level you’re shopping for.

Prices start at $50,150 for the entry-level S petrol, and climb to $72,910 for the top-spec GT-Line diesel. There’s also a GT-Line Hybrid, which tops the group at $76,210, but it’s not here yet, so we’ll cross that electrified bridge when we get to it and stick with the ICE range for now.

The range opens with the S ($50,150 petrol, $52,380 diesel), which scores 17-inch alloys, LED headlights and DRLs, heated mirrors, cloth seats, an electronic parking brake, and a smart key with push-button start, which is new for this update.

On the tech front, there is a new integrated 4.0-inch driver display, and a new 12.3-inch central screen with Apple CarPlay and Android Auto, linking with an eight-speaker sound system, now with a surround-sound function.

Stepping up to the Sport ($56,050 petrol, $58,280 diesel) adds 18-inch alloys, rear LED combination lamps, a leather steering wheel and shifter, and dual-zone climate up front with single-zone temperature control in the second row. New for this update is a wireless charging pad and artificial leather seats. 

Next is the Sport+ ($62,380 petrol, $64,610 diesel), which gets a whole host of new safety equipment, which we will come back to in a moment, along with a powered tailgate, automatic sliding doors and auto windows, and heated seats in the first and second rows. It also ups the tech, with twin 12.3-inch screens taking care of multimedia and driving info duties.

Then comes the GT-Line Lite ($66,350 petrol, $68,580 diesel), which is fitted with bigger 19-inch alloy wheels, scores LED interior lighting, gets a dual-pane auto sunroof and some chrome embellishments on the exterior. The trade-off, though is that the powered windows are now for the driver only, as is the powered front seat.

Finally, there’s the flagship GT-Line ($70,680 petrol, $72,910 diesel), which nabs dual-projection headlights, a heated steering wheel, a 12-speaker BOSE sound system, ventilated seats up front, a big head-up display and a digital rear-view mirror, along with a slightly better interior treatment and the return of the auto window and powered seat to the passenger side of the car.

While BYD has made its name in Australia as an all-electric brand it has always referred to itself as a 'new energy' company, and the Sealion 6 (and upcoming Shark ute) are why.

That’s because these feature BYD’s new 'Dual-Mode Intelligence' (DMi) powetrain - a hybrid system to you and me.

As mentioned above, the biggest difference between the Dynamic and Premium models is the powertrain, with two reasonably different systems.

The Dynamic is powered by a 78kW/135Nm 1.5-litre four-cylinder petrol engine, paired with a 145kW/300Nm electric motor - making for a combined system output of 160kW/300Nm. Notably, this powertrain only drives the front wheels.

In contrast, the Premium has an all-wheel drive set-up, combining a turbocharged version of the petrol engine (good for 96kW/220Nm) with a pair of electric motors, one on the front axle and one on the rear to produce a combined output of 238kW and 550Nm.

Both models get the same 18.3kWh ‘Blade’ battery, which is BYD’s proprietary technology underpinning all of its models and is attracting attention from other brands.

For reference, the Outlander PHEV has a 20kWh battery, Nissan’s X-Trail e-Power has a 2.1kWh battery, while the more conventional RAV4 Hybrid has just a 6.5Ah battery.

There are two ICE options on the table here. The first is what I reckon is the lesser of the two, a 3.5-litre petrol V6, producing a rev-happy 216kW and 355Nm.

The better option, I think, is the 2.2-litre, four-cylinder diesel, which makes 148kW and 440Nm, and just suits the nature of the car a little better.

Both pair with an eight-speed automatic, and send their power to the front tyres.

There are multiple modes to drive it in, including electric only, with the Dynamic able to go up to 92km on a single charge, while the Premium manages a claimed 81km.

However, it's important to note these are the NEDC standards and not the more real-world like WLTP,  so you may not achieve those in practice.

The claimed fuel consumption is an impressive 1.1L/100km for the Dynamic and 1.4L/100km for the Premium although again achieving those in the real world will take some effort.

With a 60-litre fuel tank BYD claims the Dynamic has a driving range of just over 1000km, while the Premium can manage around 960km.

It's also worth noting the Sealion 6 comes equipped with vehicle-to-load charging which means you can draw power from the batteries to run small electronic devices if you need to.

It’s a bonus feature that may or may not be of use, but is one of those things that may come in handy one day to get you through a camping trip or a BBQ at the park.

The petrol engine will sip a claimed 9.6 litres per hundred kilometres on the combined cycle, and produce 220g per kilometre of C02. The diesel lowers both those numbers, to 6.5 litres and 170 grams.

Both models are fitted with a 72-litre fuel tank, which means you’ll be sailing well north of $100 to fill one up.

We drove the Sealion 6 Dynamic and despite having the less powerful powertrain it feels good on the road. The DMi system offers good performance, with quiet acceleration off the mark and a good integration between the petrol engine and electric motors. We haven’t driven the Premium yet, so we can’t make any comment on how different it feels.

It’s hard to make a definitive call on the Sealion PHEV powertrain because, like every plug-in hybrid, its greatest strength relies on how the owner operates it.

If you don’t charge the battery every day or so, you’ll just end up lugging around a battery and electric motor for little benefit. However, if you do keep the battery topped up, you can do most of your urban commuting without needing to turn the petrol engine on, which should result in some very low fuel consumption figures.

The company clearly knows this, which is why BYD Australia is offering a complimentary home charger to the first 3000 customers who order a Sealion 6.

Not only will that encourage sales but it will also help owners become evangelists for PHEVs in the future, because they’ll have the best possible experience.

So, a large part of its strength or weakness rests on the owner’s behaviour and that’s something we can’t assess.

As for the rest of the driving experience, the ride comfort is fine. It can’t match the class-leaders for compliance or dynamics, but the Sealion feels pleasant to drive around the urban environment and on the freeway at speed.

Biggest criticism is the steering is very, very light. While that makes parking easier, it feels so light you get very little feedback from the front wheels so it can feel vague at times.

Overall the driving experience is best described as fine. It doesn’t have any major vices but neither does it set any new benchmarks. 

Forgive the horrific paraphrasing, but it seems rumours of the death of diesel have been greatly exaggerated, at least when it comes to the Kia Carnival.

Get this – diesel sales make up some 90 per cent of the Carnival's total haul, with petrol providing a pittance towards the sales total, presumably being picked up by fleet buyers.

And to be honest, that means nine out of 10 people are making the right choice here. Yes, the petrol makes more power, but it's the torque on offer from the diesel that makes pushing the Carnival around feel far more effortless.

The petrol engine can definitely get you moving, but it feels a bit too rev-happy and thrashy when you really put your foot down, and its significantly thirstier to boot.

The diesel isn't perfect – the thrum of the engine is a constant companion whenever you put your foot down, and there's actually too much torque on offer at times, like if you're accelerating up hill from a standstill on a damp road, and so the front tyres can scrabble and scramble for grip.

But it otherwise so perfectly suits the nature of the Carnival that it is definitely the best and most satisfying choice.

Another big change for this update is the fact that Kia's complete ride and handling program has been rolled out here. Kia says local work done on the outgoing car, the one this replaces, was curtailed by Covid and bushfires, and so ended up being done by correspondence.

This one, though, has had the whole enchilada thrown at it, and it shows. They've succeeded in making a bigger car feel smaller around you. It's not a sports car by any measure, but nor does it ever feel too big and unwieldily.

Part of that is down to the steering, which is direct and confidence inspiring, but mostly I suspect it's because of the ride, which is firmer than you might expect in a family hauler, but also offers a connection to that road below that makes you feel in control.

Whether a firm-ish ride is a perk or negative is up to you, but it definitely works for me.

Part of the change package for this updated Carnival is in its safety kit, some of which simply wasn’t available when Kia launched its predecessor.

Which is why every model now gets a centre side airbag, 'Forward Collision Assist AEB', 'Rear Occupant Alert', 'Trailer Stability Assist' and front parking sensors, joining the rear ones that were already there.

Sport+ Models and up now add a 'Blind Spot View Monitor' and rain-sensing wipers, as well as rear AEB through the 'Parking Collision Avoidance' function.

I have to say, though, when your entry-level car is $50k-plus, there’s no real excuse for limiting the best safety kit to the upper-spec models.

Also standard are lane keep assist, with 'Lane Follow Assist', multi-collision braking, a speed-limit warning (which you will turn off) and a reversing camera.

The Carnival range carries a five-star ANCAP safety rating, which it earned in 2021.

BYD is a small company but has partnered with mycar service centres to make maintaining your Sealion 6 easier. The Sealion is covered by BYD's six-year/150,000km warranty as well as its 10-year capped price servicing plan.

Service intervals are every 12 months/20,000km and prices range from $265 up to $1184 for the major eight year/160,000km tune up. Over the first five years, in keeping with most of its rivals, you’ll be paying $1648.

As I’ve written in previous BYD reviews, the biggest question mark hanging over the brand is arguably its long-term prospects. Quite simply, the brand is still too new to know how well it will perform on the used car market.

We also can’t tell you how it will hold up from a reliability point-of-view. We’re not suggesting there’s any doubt over its quality, but each car brand must prove itself reliable and dependable over time, and BYD hasn’t had that time yet.

Like all Kias, the Carnival arrives with a seven-year, unlimited-kilometre warranty, with capped-price servicing throughout.

Kia’s servicing costs are higher than some of its competitors, though, so you might want to compare them, as well as compare what’s included, and the diesel model will usually cost slightly more to maintain than the petrol version.

Service intervals are every 12 months or 15,000kms, and while the brand is still finalising the petrol servicing costs, the diesel prices are $386, $682, $480, $869, $434, $845 and $461, covering the first seven years of ownership.
