BYD Sealion 6 vs Ssangyong Rexton

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.

If KG Group can provide the long-term stability and new model investment that has eluded SsangYong for so long, the brand could have a promising future in Australia judging by the MY24 Rexton Adventure. It’s a solid package and what it lacks in benchmark ANCAP safety and third-row comfort is offset by a compelling driveaway price, generous warranty and national dealer network. So, if you’re looking for a feature-packed 4x4 seven-seater SUV for less than $55K, you might be pleasantly surprised by this competent Korean.

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.

With its 4850mm overall length and 1960mm width, the Rexton rides on a 2865mm wheelbase with a compact 11-metre turning circle.

Its smooth ride comes from four-coil suspension with double-wishbones up front and an independent multi-link arrangement in the rear. For those venturing into the rough stuff, it has 20.5 degrees approach and departure angles, 20 degrees ramp break-over angle and 203mm of ground clearance.

Looks are subjective, of course, but we reckon it has attractive and cohesive styling, with its prominent and ornate diamond-style grille complimented by distinctive side-body contours that can’t be mistaken for other SUVs.

The interior has a premium look and feel, with lots of exposed stitching along soft-touch seams and a tasteful blend of contrasting surfaces including chrome, satin chrome, piano black and textured patterns.

There’s good attention to detail and build quality is excellent, but there are some annoying design quirks like the need for the front passenger to access a touchscreen menu just to adjust the audio volume.

The second-row of seating has a/c vents in the centre console and is spacious even for tall people like me (186cm). When sitting behind the driver’s seat in my position, there’s about 60mm of clearance between my knees and the driver’s seat backrest, which combined with ample head and shoulder room makes for a comfortable ride.

By contrast, the third-row seating is strictly for young kids, as there are no adjustments for the second-row’s backrest angle or fore/aft base cushion positioning to accommodate taller frames like mine. The side windows in the thick rear roof pillar are also conspicuously small, which adds to a claustrophobic feel.

Fortunately, access to the third-row is made easier by the 60/40-split second-row, which can be folded and tumbled forward.

However, given I’ve found tolerable third-row comfort in some rival seven-seaters, the Rexton’s third-row is my only gripe for those with longer limbs.

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.

With its 2130kg kerb weight and 2960kg GVM, our test vehicle has a sizeable load capacity of up to 830kg, which should be ample for five occupants and their luggage.

It’s also rated to tow up to the class-benchmark 3500kg of braked trailer and its 350kg maximum tow-ball download is compatible with that requirement.

Plus, its generous 6460kg GCM (or how much it can legally carry and tow at the same time) means it can legally tow its maximum trailer weight while carrying its maximum car-load, which is a practical set of numbers for just about any recreational requirement.

Front-row cabin storage includes cup/bottle-holders and a small bin in each front door, plus a single glove box. The stylish centre console has a bin up front with sliding-lid, two cupholders in the middle with another sliding-lid, plus a box at the rear with hinged padded-lid that doubles as a driver’s elbow rest.

Those seated in the second-row get a cup/bottle holder and bin in each door, plus pockets on each front seat backrest. The fold-down centre armrest has two more cupholders and a handy hidden compartment that’s ideal for small items. Third-row occupants get storage bins on each side but no cup/bottle holders.

Accessing the cargo area through the power tailgate reveals 236 litres (VDA) of load volume with the third-row seats upright. This expands to 641 litres with the third-row folded flat and 1806 litres (or more than 1.8 cubic metres) with the second and third-rows folded.

The cargo area’s rear floor has a two-tiered design, with the top floor lying flush with the third-row seats when folded but it can be removed to reveal a lower floor that provides a second level of storage. There’s also a usefully large bin in the right-hand-side wall cavity. The only things missing are sturdy load-anchorage points at floor level to secure cargo nets or straps.

Our test vehicle is the new ‘Adventure’ model, which serves as the middle-grade offering between the entry-level ELX and top-shelf Ultimate.

It’s equipped with the same 2.2-litre four-cylinder turbo-diesel, eight-speed automatic and part-time 4WD as other Rextons, for a drive-away price of only $54,000 (our 'Space Black' metallic paint is a $595 option).

That pricing looks razor-sharp compared with mid-grade 4x4 seven-seaters offered by segment leaders like the Isuzu MU-X LS-U ($61,400), Ford Everest Trend ($66,790) and Toyota Prado GXL ($69,530).

And they are 'list' prices (not including on-road costs) whereas the Rexton is 'drive-away-no-more-to-pay'.

The MY24 upgrades include a new dash layout and high-mounted 12.3-inch multimedia touchscreen with Apple/Android wired connectivity. There’s also a restyled dual-zone climate control hub with touchscreen, plus new lower body mounts for improved ride quality.

The Adventure brings numerous luxuries like a walk-up welcome system (mirrors unfold and puddle lamps illuminate), touch-sensing front door locks with walk-away auto door-locking, power tailgate and soft-touch synthetic leather seats with the fronts offering power adjustment, heating and cooling.

The second-row outer rear seats and steering wheel are also heated, plus there’s speed-sensitive power steering and tyre pressure monitoring.

These appointments are in addition to the base ELX’s generous standard equipment list including 18-inch 'diamond-cut' alloy wheels with 255/60 tyres and a full-size alloy spare, LED dusk-sensing headlights/DRLs/front fog lights/tail-lights, heated door mirrors, a four-way-adjustable leather steering wheel and 12.3-inch driver's digital instrument display.

There are also four USB-C ports (two front and two in second row centre console), three 12-volt outlets (front console box, second row centre console and cargo area), electric parking brake, reversing camera, front and rear parking sensors and more. It's fair to say the Rexton Adventure is feature-packed.

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.

The quiet and refined 2.2-litre, four-cylinder, turbo-diesel, which meets Euro 6 emissions standards, produces 149kW at 3800rpm and 441Nm across a 1000rpm-wide torque band between 1600-2600rpm. It provides energetic response in city and suburban use.

This engine is paired with an equally refined eight-speed torque converter automatic, with overdrive on its sixth, seventh and eighth ratios ensuring low-rpm operation and optimum fuel economy at highway speeds.

Sequential manual-shifting is available using the steering wheel-mounted paddles and there's a choice of three drive modes ('Power'/'Winter'/'Eco') which can be selected using a console button.

The part-time, dual-range 4WD system is controlled by a console dial, offering the choice of 2H (2WD high-range), 4H (4WD high-range) and 4L (4WD low-range). It also has an auto-locking rear diff to optimise traction as required.

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.

SsangYong claims an official combined cycle average of 8.7L/100km. At the completion of our 307km test, which comprised mostly city and suburban driving with a bit of highway travel, mostly in Eco mode with up to five occupants on some trips, our figure calculated from fuel bowser and trip meter readings came in at 11.0L/100km.

Although higher than SsangYong’s claim, it was within the usual 2.0-3.0L/100km discrepancy between official and ‘real-world’ figures. So, based on our numbers, you could expect a driving range of more than 600km from its 70-litre tank, which is not bad. Based on the official figure, driving range extends to around 800km.

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 Rexton’s overall refinement and build quality are evident when you get behind the wheel. It offers good adjustability for driver comfort and the fundamentals of the vehicle are sound, as there were no red flags during our test.

The engine is smooth and quiet with good all-around performance, the automatic transmission shifts quickly and smoothly, the steering is nicely weighted and communicative, the brakes provide reassuring response and the ride quality is supple over bumps yet disciplined enough to provide good handling response.

It’s also pleasantly quiet at highway speeds, with low tyre and wind noise. Engine noise is also minimal, given that it requires only 1600rpm to maintain 110km/h, ensuring low-stress cruising.

Most of our driving time was spent in Eco mode, as we found performance in this setting more than adequate for our purposes. We did briefly use the Power mode but didn’t notice any significant change in response.

No ANCAP rating (as yet). Even so, it comes with numerous passive and active safety features highlighted by dual front, side and curtain airbags plus a driver’s knee protection bag (but no centre airbag between driver/front passenger).

There’s also AEB, lane assistance, blind-spot warning and rear cross-traffic alert, trailer sway control, hill descent control, front/rear parking sensors, reversing camera and more, but a notable absentee is speed-sign recognition and the cruise control is non-adaptive. There are also ISOFIX child seat anchorages on the two outer second-row seating positions plus top tethers for all three.

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.

Warranty cover is seven years/unlimited km warranty plus seven years roadside assist.

Scheduled servicing is every 12 months/15,000km whichever occurs first.

The first seven scheduled services run to $375 each, up to seven years/105,000km, for a total of $2625.
