BYD Sealion 8 vs Kia Sorento

What's the difference?

There’s quite a bit to like here. There’s plenty of equipment, and lots of choice in price, trim level and mechanical complexity.

The driving dynamics are fine if you’re not looking for anything sporty although the performance offered by the dual-motor variants must be considered excessive, even if it’s pretty exciting the first time.

Perhaps what’s missing from the Sealion 8 experience is anything that stamps the car as something special within its hotly-contested market segment. Which is another way of saying it offers up the same limitations, most notably in the third row accommodation and access.

You only need to drive a one-box people mover and utilise the rearmost seat, to understand that the two-box SUV, while a pretty marketable thing, is compromised once the passenger count exceeds five. Nothing new there, but nothing new in the BYD, either, to change that narrative.

At which point, the front-wheel drive variant emerges as the most pragmatic choice and probably the one that meets all the important family tasks headed its way for the smallest outlay.

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.

BYD has done its best to give the Sealion 8 its own character and vibe. In fact, it’s a pretty smart looking thing - although still very much a two-box wagon concept - and that’s no given when you consider how much some big SUVs can start to look like large blobs of nothing when you look closely.

There’s the usual Darth Vader stuff at the front, but in profile, the diagonal vent across the front door makes a bit of a statement. The 'plaited' motif of the tail-lights might be stretching things a bit, though.

Inside, the modern board-room feel is invoked by the angular lines and high-tech look and feel of the large info-screens. The panoramic sunroof of the Premium grade also helps brighten up an otherwise pretty dark space.

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.

BYD has made sure all three rows of the Sealion 8 are fit for purpose while attempting to make the rearmost row (traditionally the trickiest to get right) less of a downmarket place to be. With that in mind, both rear rows get air vents and climate-control adjustment for that part of the car. There's also a pair of USB-C charge ports in the second row and a single USB-C and USB-A port in the third row. The third row also has cupholders bult into the wheel arch on each side.

With the third row in place, there’s a decent amount of luggage space (270 litres) largely thanks to the Sealion’s five-metre overall length. There’s no spare tyre, but a puncture repair kit lives under the floor (as does the removable cargo blind) and the rearmost luggage space also incorporates a 12-volt socket and luggage hooks.

A pair of pull-tabs drop the headrests and then the entire split third row in a single movement, at which point you suddenly have a five-seater with a huge, 960 litres of luggage space. And if you need to cart gear over people, the second row also folds flat to open up 1960 litres of space.

Up front, the feeling of spaciousness is amplified due to the low scuttle height and what the aviation industry calls the glass cockpit (no analogue dials or gauges at all). The 15.6-inch central info-screen runs the usual apps and control displays but, thankfully, the climate control touch-controls are tethered to the bottom of the screen, so they’re always visible regardless of what else is going on.

The 10.2-inch driver’s display adds a head-up function in Premium trim and displays the usual array of information required to operate the vehicle. But even better is the steering wheel which features a thick, well-padded rim that looks and feels pretty luxe. It also houses the usual buttons for stereo, phone and cruise-control functions.

A really nice touch is the addition of an extra set of tilt controls on the inside of the passenger’s front seat, allowing the driver to control that seat to allow people in or out without leaving their own seat. Nice one.

It is, of course, the centre row of seats that will make or break a car like this for many families. Even though many clans will not use the rearmost seat much of the time, the central row will get a huge workout. So it’s nice to see that leg, foot and headroom are all sufficient for even growing teenagers. Again, the car’s overall length appears to be the key, but it’s also worth noting the centre row seat is comfy and supportive. The outboard positions in the second row also feature heating and ventilation functions.

The third row, however, follows SUV tradition by being strictly for smaller kids. Access past those huge wheel arches is tight, and once you’re in, there’s a combination of dark trim and tiny windows to limit joy.

While it won’t matter to many buyers, the front-drive Sealion 8 is rated to tow 1800kg with a braked trailer, and up to two tonnes in the all-wheel drive version. But there’s no spare tyre fitted, and roadside flats need to be addressed by the included tyre repair kit.

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.

BYD has managed to keep a lid on the price of the entry-level version of the Sealion 8, by specifying it with front-wheel drive rather than the all-wheel drive of the other two variants. It still gets the same driveline beyond the lack of a driven rear axle, although battery capacity is the other difference.

As such, you’re looking at a 1.5-litre petrol engine (kind of the default powerplant for Chinese SUVs right now) with a turbocharger. With the 19kWh battery chiming in to power the electric motor, the driveline can achieve outputs of 205kW and 315Nm.

In the case of the AWD variants, the larger 35.6kWh battery and extra electric motor ups the potential outputs to 359kW and 675Nm which is a huge jump any way you look at it and gives the Sealion 8 a huge bandwidth when it comes to matching buyer performance aspirations.

All the variants have the potential for a claimed electric-only range of greater than 100km if owners use the plug-in facility to charge either at home or at work. For the AWD variants, the larger battery stretches the EV range to a claimed 152km. On longer journeys or whenever the battery has reached about 25 per cent capacity, the Sealion 8 acts just as any other hybrid with regenerative braking and electric assistance to aid performance.

In suspension terms, the BYD is pretty conventional but if you do pay the extra for the Premium variant, you’ll gain adaptive dampers.

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.

BYD claims a range of more than 1000km for both variants of the Sealion 8, provided you start with a fully charged battery and a full 60-litre fuel tank.

The BYD can also make use of commercial fast-chargers and, when using the maximum 40kW on the FWD version and the 74kW possible for the AWD variant, the charging times from 30 to 80 per cent are both under 20 minutes. The Sealion 8 can also charge at 11kW on an AC socket and the vehicle also offers V2L (Vehicle to Load) capability, meaning it can power on-site work tools, camping gear or even your house at night.

Provided the EV battery is kept at 25 per cent capacity or above, BYD claims a 1.0-litre per 100km fuel consumption figure for the car based on the laboratory test. In the real world, the results will vary enormously depending on where you drive and how the car is used. Deplete the battery and continue to drive at highway speeds, and your actual fuel consumption might easily increase to many times that 1.0-litre claimed figure.

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.

The first thing you’re going to do in a Sealion 8 is wonder where the gearshift is. It’s a column-shift, but it's not only located where a traditional indicator stalk would be, it looks very much like one, too.

This promises two things. One, you’ll spend a few seconds finding it and two, you’ll try to turn the indicators on with it at least once every drive. (The real indicators are on the other side of the steering column.)

Another note to those test driving a Sealion 8. Sample the front-drive version first. (I’ll get to why in a minute.) When you do, you’ll soon figure out this is a driveline that prioritises electric running. That is, the petrol motor barely ever actually drives the wheels (only at full throttle and higher speeds). Any other time, if the petrol engine is running, it’s to charge the battery that keeps the electric motor purring away. This is how efficiency is defined by BYD.

You’ll also find that the Sealion’s acceleration is purposeful in that electric-motor way, but hardly startling. And when you do smash the throttle and force the petrol engine to drive the axle, you’ll notice that this takes a fair time to play out, and that when everything is grunting as hard as possible, the petrol engine is quite noisy and even a little harsh sounding. Use the driveline sensibly, though, and it’s all smooth and quiet, even if that then means you can hear a little suspension noise creeping into the cabin.

That done, you’re now free to drive the AWD variant. Why wait? Because this thing is seriously off the leash. Bear in mind that 359kW of power is getting on for the thick end of 500 horsepower in the old money, so even though the Sealion 8 is a hefty critter at about 2.5 tonnes, all that power and torque will get it from rest in under five seconds, or thereabouts. The relevance of this to family-car technology is hugely debatable, but it’s one heck of a party trick the first time you try it.

The huge torque also magnifies the Sealion 8’s natural tendency to lift its inside front wheel when accelerating out of a turn. A small tyre squeak can sometimes be heard before the traction control gathers it all together, but even the single-motor variant displays the same trait.

In steering and suspension terms, it’s probably fair to say the Sealion 8 doesn’t unlock any new depths of talent. The ride is pretty comfy but at the expense of body control and the steering points the wheels but doesn’t convey much else to the driver.

That said, the fact everything seems to be tuned to the same frequency means it all works okay. You don’t have too-fast steering fighting the tyres or too firm suspension upsetting the interior calm. Use it as a family would, and it’s 100 per cent fit for purpose.

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.

Servicing any hybrid can be a bit more expensive thanks to the presence of two propulsion forms.

In any case, the Sealion 8 requires routine servicing every 12 months or 20,000km.

Warranty is BYD’s normal six-year/150,000km cover, although there’s also eight years and 160,000km of cover for the EV battery.

BYD also claims its 'Blade' battery technology is among the safest in the business, and says the design resists damage (and, therefore, the risk of fire) better than the competition.

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.
