BYD Sealion 6 vs Kia Sorento

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.

The Kia Sorento GT-Line PHEV is a sumptuously equipped seven-seater that delivers comfort, tech and an easy-going drive. It presents well on the surface, and for the right buyer (one who can make the most of its plug-in capabilities ) it could be a smart, low-emissions option for family life.

But for all its polish, it doesn’t quite do enough to justify itself as the best Sorento in the range. The electric-only driving range isn’t especially generous, and the higher price tag , combined with its lower towing capacity, may leave some families wondering whether the diesel variant is the more practical choice.

It’s not a bad car by any means, but the flagship GT-Line PHEV feels more like a stepping stone than a standout.

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.

The Sorento looks exactly how a modern SUV should - confident, capable, and well-proportioned without feeling bulky. It wears its size well, delivering that commanding presence families often want in a seven-seater, without coming across as too aggressive.

I especially like the 19-inch alloy wheels as they suit the vehicle’s stance perfectly. I also like the striking LED lighting signatures front and rear, which really come to life after dark.

Step inside and the cabin strikes a neat balance between tech-forward and user-friendly. You’re greeted by dual 12.3-inch widescreen displays that make a strong first impression, but thankfully Kia hasn’t gone all-digital! You still get physical buttons and dials where they matter, making everything feel intuitive and easy to navigate.

Material quality is a highlight. There’s quilted Nappa leather upholstery, soft-touch surfaces throughout, and even a luxe suede headliner. These premium touches, coupled with the panoramic sunroof, lift the ambience and it's a cabin that feels genuinely upmarket, but not at the cost of family friendly functionality.

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.

Space up front is generous, with excellent seat comfort thanks to wide seat bases, extendable under-thigh support and heating and ventilation. Getting in and out is easy, too, helped by wide door openings and a manageable 176mm ground clearance.

Storage throughout the cabin is thoughtful and abundant. Up front, there’s a large glovebox, a spacious centre console with a removable shelf, two cupholders, door bins with bottle holders, and a handy phone cubby beneath the dash.

The second row adds its own bottle holders and storage bins in each door, map pockets, four cupholders (including one cleverly placed on each door) and a removable floor shelf in front of the centre seat.

Even the third row isn’t forgotten, with a snack cubby and cupholder built into each wheel arch.

Tech-wise, the dual 12.3-inch displays look sharp, and the media system is intuitive and quick to respond. The instrument cluster isn’t particularly customisable, and I’m not a huge fan of the layout, but it displays the essentials clearly. You also get a head-up display, satellite navigation with over-the-air updates, and both wireless and wired Apple CarPlay and Android Auto.

Charging options are solid across all three rows, with multiple USB-C ports, a 12-volt socket in the second row and boot, and a wireless charging pad up front.

The second row offers ample legroom, though headroom is slightly reduced due to the panoramic sunroof. The lack of a transmission tunnel is a win for middle seat comfort, and the bench is wide enough to accommodate three child seats side-by-side. There are three top-tether points and ISOFIX anchors on the outboard seats.

Comfort and convenience features in the second row include heated outboard seats, device pockets, directional air vents, and the same handy storage and charging options mentioned earlier. My son especially loves the retractable sunblinds and the cupholders built into the door handles as they’re easy to reach and super practical. I am, however, disappointed that there’s no separate climate control zone for this row.

As for the third row, it’s best treated as a sometimes seat for adults. Access is more child-sized, and amenities are limited, but you do get directional air vents and a fan control, which are definitely appreciated.

Boot space is tight with all three rows in use, at just 175L, but that was still enough for the odd errand during the week. Fold the third row down and you get a much more usable 604L. Both rows fold completely flat, making it easy to slide in larger items, and the GT-Line includes a powered tailgate and a rare full-size spare wheel for extra convenience.

There are five grades in the Sorento line-up, and this week we're behind the wheel of the flagship GT-Line PHEV AWD. This is the most expensive Sorento you can buy, with a price tag of $84,660 before on-road costs — about $15,000 more than the equivalent petrol or diesel GT-Line variants.

That’s a hefty premium, but when you stack it up against other plug-in hybrid rivals, like the (albeit-premium) Volvo XC90 Ultra Recharge which starts at $124,466 or the BMW X5 xDrive50e with its $125,885 MSRP price tag, the Sorento PHEV starts to look like a more affordable entry point to electrified family motoring.

As the range-topper, the GT-Line doesn’t skimp on equipment. You get all the luxury touches like, heated and ventilated power front seats with memory functionality, heated rear outboard seats, a heated steering wheel, wireless Apple CarPlay and Android Auto, a panoramic sunroof, six USB-C ports and two 12-volt sockets, and a 12-speaker premium Bose sound system.

It also features quilted Nappa leather upholstery, customisable ambient lighting, dual 12.3-inch displays for multimedia and instrumentation, digital radio, Bluetooth connectivity and Kia’s clever Passenger Talk function, which lets the driver’s voice reach the third row through the speakers (a feature many parents will quietly cheer for).

There’s no shortage of thoughtful family focused features either, including rear window shades for the second row, a powered tailgate (operable via the driver’s seat or key fob), remote smart parking assist, one-touch sliding second-row seats, a third row that folds flat, and dedicated fan control in the rear.

The biggest question, though, is whether all of this plus the new plug-in hybrid powertrain is enough to justify the price jump.

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.

Powering this GT-Line variant is a plug-in hybrid system that pairs a 1.6-litre turbocharged four-cylinder petrol engine with a small electric motor and battery. Combined, the system delivers up to 195kW of power and 350Nm of torque, which is plenty to get this sizeable SUV moving with confidence.

It’s a part-time all-wheel-drive set-up with a lock mode for extra traction when needed, and it’s paired with a smooth-shifting six-speed automatic transmission.

Around town and on the highway, the power delivery feels seamless and refined, with the electric motor doing a nice job of smoothing out stop-start driving.

One key trade-off, however, is towing capacity. While the diesel Sorento can tow up to 2000kg braked, the PHEV’s figure drops to just 1010kg. That’s a significant reduction and could be a deal-breaker for families who regularly tow a camper, trailer or boat.

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 Sorento GT-Line PHEV offers a WLTP-rated electric-only driving range of up to 57km - not huge, but enough to cover most daily commutes or school runs without dipping into the petrol tank.

When driven as intended and regularly charged, it’s capable of a combined fuel consumption figure as low as 1.6L/100km and this is paired with a 67-litre fuel tank. That means you could go a seriously long time between fill-ups if you’re topping up the battery daily.

In my week of testing, which included a mix of highway stints and urban errands, the trip computer reported an average of 7.2L/100km.

That’s well above the official figure, but still pretty reasonable considering the type of driving I was doing.

Charging is simple enough. The Sorento uses a Type 2 charging port, and on a standard 3.3kW AC charger, the 14kWh battery can be charged from 15 to 95 per cent in about three hours and 26 minutes.

Kia includes a portable AC charger with this grade, which is a handy bonus for charging at home or on the go.

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. 

The Sorento PHEV hits most of the right notes when it comes to power delivery and gear shifts. Occasionally, there's a slight hesitation between whether the engine or electric motor should take the lead - like a dance partner who’s just a touch out of step. It’s noticeable, but not disruptive.

Most of the time, the transition between power sources is smooth, and there’s more than enough grunt for overtaking or merging confidently.

The suspension has a springy, soft edge to it and you’ll feel some movement over bumps but it’s never harsh or uncomfortable. It corners surprisingly well for a large SUV, with responsive, albeit lighter, steering. Body roll is present if you push into tight bends, but that's par for the course in a seven-seater.

Regenerative braking is subtle, almost too subtle. There’s not much feedback, and it can feel a bit heavy underfoot in stop-start traffic. It’s not a deal-breaker, but worth noting if you’re expecting the more pronounced regen feel you get in some other hybrids or EVs.

The cabin remains quiet at both urban and highway speeds, making it easy to hold a conversation across all three rows. Visibility is generally good, though the thicker pillars take a little getting used to. The digital rearview mirror is a great touch when the back seats are loaded with people or gear.

Parking is refreshingly simple thanks to a crisp 360-degree camera and front and rear sensors. One of my favourite features is the remote smart parking, which lets you move the car forwards or backwards via the keyfob, a lifesaver in tight parking spots. Just don’t teach your eight-year-old how to use it ...

The Sorento PHEV shares its five-star ANCAP safety rating with the rest of the Sorento range, based on testing conducted in 2020. It comes with seven airbags, although it’s worth noting that the curtain airbags don’t extend to the third row, which is a disappointing oversight in a family focused seven-seater.

That said, the GT-Line PHEV still brings a solid suite of safety tech. A standout is the blind-spot view monitor, which displays a live video feed of your blind spots in the instrument panel whenever you indicate and it’s one of those features you quickly grow to rely on! There’s also emergency call functionality, a digital rear-view mirror, and safe exit assist to help avoid incidents with passing traffic when opening doors.

A welcome update is those notorious Kia speed limit beeps and alerts can now be easily silenced via the steering wheel. It’s a small thing, but it makes a big difference to the overall driving experience.

Standard safety features include blind-spot monitoring, rear occupant alert, forward collision warning, rear cross-traffic alert, lane-keeping assist and lane departure warning, driver attention alert, intelligent seatbelt reminders (six seats), front and rear fog lights, and LED daytime running lights.

Autonomous emergency braking (AEB) is also standard, with vehicle detection from 5.0 - 75km/h, and pedestrian, cyclist and reverse AEB support from 5.0 - 85km/h.

For child seat installation, there are three top-tether anchor points and two ISOFIX mounts in the second row. That’s enough flexibility for most families, though it would be nice to see more child-restraint coverage further back.

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.

The Sorento is backed by Kia’s seven-year/unlimited-kilometre warranty, which keeps the Sorento competitive in a market that is slowly starting to offer seven/year plus terms as standard.

You’ll also benefit from capped-price servicing for up to seven years or 70,000km, with an average cost of $764 per visit. That’s on the pricier side, especially when compared to some rivals.

Service intervals are every 12 months or 10,000km, whichever comes first, so if you’re someone who racks up the kilometres quickly, that could mean more frequent trips to the service centre than you’d like.

It’s also worth noting that the GT-Line PHEV requires a minimum of 95 RON premium unleaded petrol, which is something to factor into your ongoing running costs, particularly if you're already trying to offset fuel usage with regular charging.
