BYD Sealion 6 vs Jaecoo J7

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 Jaecoo J7 SHS Track enters the medium SUV segment with a sharp drive-away price and generous equipment list. The ongoing ownership benefits add strong value but the on-road driving experience needs some finessing and the cabin doesn't quite hit every mark for practicality. Although it's ‘on track’ to make waves in this corner of the market, it hasn't yet carved out an iron-clad niche for itself. It's worth a look but it's not class-leading.

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 J7 is, in essence, a scaled-up version of its smaller sibling, the J5 - a car my family affectionately dubbed the “Temu Range Rover” during our week with it. The resemblance remains.

The squared-off proportions, upright grille and slim lighting signatures lean heavily into that premium off-roader aesthetic, and there’s no doubt the look will appeal to buyers chasing presence without the associated price tag.

Compared to the J5, the J7 carries a touch more personality. 

There’s a small racing-flag accent panel along the flanks, flush-fitting door handles and a set of 19-inch aerodynamic alloy wheels that add some visual flair.

Inside, the cabin is cleanly executed with its pared-back styling and the 13.2-inch central display dominates the dashboard. This makes it the visual anchor of the interior as physical buttons are minimal and most functions are accessed via the media screen. That screen-led design will divide opinion, but it does create a modern aesthetic.

The synthetic leather upholstery feels convincingly premium, and the materials do enough to lift the ambience beyond what you might expect at this price point.

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.

Up front, the J7 Track delivers where it matters. The electric front seats offer heating and ventilation functions and feel supportive over longer drives. There’s enough width and shoulder room to avoid feeling hemmed in.

Access is good with wide door apertures and an easy step-in, step-out height from both rows. In the rear, the available space is generous, and the thick seat padding and supportive backrests will make longer journeys quite comfortable. The flat floor also means the middle seat isn’t automatically the punishment position for an adult.

Storage has been thoughtfully considered. Up front, the large centre console shelves make it easy to keep clutter contained, while the dual-opening middle console is deep enough to swallow a small handbag. There’s also a small side pocket beside the driver that’s ideal for keys or a garage remote.

Rear passengers will enjoy four device pockets, as well as a couple of map pockets. There are two cupholders and drink bottle holders in each row, as well as good-sized bins in each door.

With all rows in use, the boot has up to 500L of capacity, and the flat loading floor makes it easy to slide larger items in and out. Overall, it’s a usable and practical space for gear storage but you'll notice the lack of a powered tailgate as there isn't a dedicated handhold on the outside of the lid to easily open the boot.

There's also no charging ports or power outlets in the boot, which feels unusual for a plug-in hybrid. You have to make do with a tyre repair kit rather than a spare wheel but that's not unusual in this corner of the market.

The individual charging options are functional with a single USB-A and C port offered in each row and a 12-volt socket up front but you miss out on a wireless charging pad in this grade. The multimedia touchscreen is responsive and the layout is fairly intuitive to use. However, the lack of physical controls for simple adjustments like side mirror positioning or climate control can become frustrating. Some functions are just better served by buttons.

The wireless Apple CarPlay and Android Auto operate smoothly and the CarPlay has maintained a steady connection this week. The built-in sat nav is also easy enough to use.

There are two plug-in hybrid grades in the J7 line-up and we’re testing the entry-level Track here, priced at $43,990 drive-away. It’s a strategic price point because aside from its close relative, the Chery Tiggo 7 Super Hybrid, which undercuts it at $39,990 drive-away, the Track is the second-most affordable option among its immediate rivals.

By comparison, the GWM Haval H6 GT PHEV lists at $51,990 drive-away, while the MG HS Super Hybrid Excite comes in at $52,696 drive-away. The BYD Sealion 5 undercuts them all as the most affordable plug-in hybrid in the country right now, starting from $33,990 before on-road costs.

It’s worth noting that the H6 GT is offered in a single, well-specified grade, and its higher price reflects that broader equipment list. Even so, the J7 starts from a strong position before you get into its features.

For a base variant, the Track gets some good stuff like electric front seats with heating and ventilation, synthetic leather upholstery, remote start with pre-entry climate control and a full suite of LED exterior lighting. That’s the sort of kit you’d expect to climb trim levels for.

Practical touches are scattered throughout. The centre console is air-cooled, the driver’s seat has a memory function, there are steering wheel-mounted controls and dual-zone climate control comes as standard. Then there’s the built-in karaoke app. Entirely unnecessary, but mildly amusing, however, you will need to supply your own microphone!

Technology feels well-considered as there’s wired and wireless Apple CarPlay and Android Auto, built-in satellite navigation, a large 13.2-inch multimedia display and a 10.25-inch digital instrument cluster. The 360-degree camera system is clear and complemented by front and rear parking sensors.

You do miss out on a powered tailgate and some charging options as there’s no internal vehicle-to-load (V2L) AC outlet and no charging ports in the boot. Still, as a base offering, the J7 Track presents as a neat package.

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.

Both plug-in hybrid grades of the J7 share the same powertrain, pairing a 1.5-litre four-cylinder turbo-petrol engine with a single electric motor. Combined outputs sit at a healthy 255kW and 525Nm which is the same as its Chery cousin and makes it more powerful than its MG rival but the GWM Haval H6 GT has bigger outputs.

However, once the EV battery is depleted and the system leans more heavily on the petrol engine, the outputs drop significantly to 105kW and 215Nm. This shifts the J7 from feeling spritely to serviceable on the open road.

Power is sent exclusively to the front wheels, and towing capacity is rated at 750kg unbraked. That’s enough for a small box trailer but it won’t be hauling any serious weekend toys.

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 J7 Track has a Type 2 CCS charging port and accepts up to 6.6kW on AC power and up to 40kW on fast DC power. On that type of DC charger you can go from 30 - 80 per cent in as little as 20 minutes which is great for when you’re on the go. You can shop and charge without much fuss.

The 18.3kWh lithium-iron phosphate battery supports an electric-only driving range of up 90km (WLTP). That sits below its Haval and MG rivals with their respective WLTP ranges of 153km and 120km. Overall though, the J7 has a theoretical driving range over around 1200km, which is great. Of course, you will only see that type of range if you regularly charge it.

Jaecoo claims a combined fuel cycle usage (urban/extra-urban) of 1.0L/100km but my real-world usage has come out at 5.0L/100km even after regularly charging it. However, it's worth noting that I do a lot of longer, highway driving which is where plug-in hybrids are typically less efficient.

Jaecoo recommends a minimum 91 RON unleaded petrol to be used for the J7.

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. 

This is where the J7 Track feels less resolved. It's not fundamentally flawed by any means but it's not as polished as it could be.

With a charged battery, acceleration is strong and immediate, and there’s enough punch for hills and confident overtaking. Even when the battery is running low, the drop in output doesn’t feel as dramatic in real-world conditions as the standalone engine figures might suggest. You won't win any drag races but it remains competent. It just loses some of the initial punch when accelerating.

Steering is light, which makes urban manoeuvring easy, and the suspension leans toward the softer side. Around town, that translates to a comfortable and compliant ride. Push it harder through bends, though, and the body control starts to feel a little loose.

Highway refinement is another area where there’s room for improvement. Road noise becomes noticeably more present at open-road speeds, although it remains quiet around town.

Visibility out the front and sides is good, and the driving position gives you a fairly commanding view of the road. I don’t feel like there are any large blind spots from my driving position.

There are three levels of regenerative braking, and running it in the strongest setting does a good job of harvesting energy. However, even on the lowest setting, the braking response feels abrupt. At low speeds when the system tends to remain in EV mode, the transition can feel lurchy.

The 360-degree camera system is clear and outside of the heavy-handed regen braking, the J7 is straightforward to park. Just be prepared for passengers, especially opinionated children, to comment on the body movement.

The J7 plug-in hybrid variant has a maximum five-star ANCAP safety rating from testing done in 2025 and scored well across its individual criteria with an 81 per cent for its adult protection, 85 per cent for child protection, 80 per cent for vulnerable road user and 84 per cent for its safety assist.

Passive safety items include eight airbags including a front centre airbag and drivers’ knee airbag. Families will like that there are two ISOFIX child seat mounts and three top-tether anchor points but realistically, two child seats will fit best. There are also manual child-safety locks on the doors, powered locks for the rear windows and intelligent seatbelt reminders for all five seats. Parking is easy with the front and rear parking sensors and 360-degree view camera system.

Active safety includes forward and rear collision warning, lane keeping aids, lane departure warning and prevention, blind-spot detection, side exit assist and a relatively unobtrusive driver monitoring system.

Other highlights include emergency lane keeping, which will activate when there’s no response from the driver and the rear cross-traffic alert also gets assisted braking. The lane keeping can oversteer at times and the adaptive cruise control is best without the assisted steering on. The J7 misses out on emergency call capability but otherwise, the safety equipment feels pretty robust.

There’s autonomous emergency braking with car, pedestrian and motorcyclist detection and is operational from 4.0 – 85km/h and up to 134km/h for car detection but it is more typical to see that top figure closer to 180km/h.

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 Chinese lucky number '8' is heavily featured in the ownership as the J7 is offered with an eight-year/unlimited km warranty, eight years of battery cover and roadside assistance, plus eight years of capped-price servicing where services average just $422 per visit. That's an impressive suite of terms for the class.

Servicing is well-spaced at every 12 months or 15,000 kilometres and for now the service network is still fairly small, with around 50 centres nationwide.
