BYD Sealion 7 vs Jaecoo J7

What's the difference?

The BYD Sealion 7 Performance is well-priced and well-equipped. It more than holds its own against its mid-size electric SUV rivals. It has great motor outputs and it handles comfortably on the road. There's a lot to like here but some of the technology needs to be tweaked.

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.

It may be named after a sea lion but it doesn’t resemble the blubbery cuteness of the creature itself. However, its sleek dynamic styling and performance outputs do call forth some of the creature's water prowess. 

This prowess is hinted at by the 20-inch alloys which are fitted with Michelin tyres and red brake calipers. There’s some Porsche-like design notes in the wide swoopy nose and LED headlights. The rear is also quite handsome with its long LED band strip and narrow window giving it a sporty silhouette.

Head inside and the Performance showcases the best BYD cabin I've sampled. There are no strange accents or panelling like there are in the Atto 3. This proves that BYD can do premium well.

The quilted leather upholstery feels supple underhand and the sports seats with integrated headrests reminds you what it can achieve in a sprint.

The swoopy design is carried over inside with the door panels. The dashboard is simply styled but headlined by an enormous 15.6-inch display that can rotate between landscape or portrait mode. Some may liken it to an iPad but it works.

The panoramic sunroof keeps things bright and cheerful but there are some simplistic elements that are hard to ignore. Like the lack of buttons, minimalist mirror cover design on the sunvisors and a rather plain-looking centre console.

Everything else flows and my favourite feature inside is surprisingly the lever door handles! They're functional but cute.

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.

The cabin has space, space and then more space. Passenger comfort is all but guaranteed with the available leg- and headroom in each row.

The functions for the electric front seats means it's easy to find a comfortable position. Door apertures are wide for each row and despite a relatively low 140mm ground clearance, it's still an easy SUV to slide in and out of.

Technology looks great and the large 15.6-inch multimedia display is what catches your eye first. Graphics are sharply rendered and the touchscreen responsive. There's a lot of information and menus embedded into the display which means it's a system that will take you a beat to get used to.

It's not unique but the in-built voice assistant rarely works as it should and needs some work. Also, because of the lack of buttons and dials, all functions are accessed via the screen. I don't like this because it tends to draw your eyes from the road far more often than it should and some functions - like the heat and ventilation for the front seats - are buried in a few menus.

There is wireless Apple CarPlay and Android Auto but there are some gremlins that need to be ironed out. The connectivity is easy enough but the steering wheel mounted phone control didn't access Apple CarPlay. So, I couldn't hang up my phone call properly, it would instead access the Bluetooth phone menu and dial my last call. I had a few 'butt' dials this week because of it.

Storage is on par with the Performance rivals and up front the burden falls across the large glovebox and middle console but there is also a shelf underneath the centre console for bigger items, like a handbag. There are two phone cradles, although only one offers wireless charging, and two height-adjustable cupholders two drink bottle holders and small storage bins.

In the rear, you get two device pockets and a map pocket on the back of each front seat. There is a fold-down armrest with retractable cupholders and a small storage pocket (think Kindle-size) and there are storage bins in each door.

The boot capacity is a decent 500L and the floor can be adjusted to two heights, one offering a level loading space. There is also a frunk storage of 58L for any cables or random bits you don't use often. Under the boot floor there is also enough room for cables and the tyre repair kit. The powered tailgate can be access via your keyfob as well.

For a flagship grade, I would have expected a few extra amenities in the rear, like climate control and sunshades but it does have directional air vents, reading lights and a USB-A and C port.

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.

The Performance is all-wheel drive and is fully electric with dual motors, a squirrel cage induction motor located at the front and a permanent magnet synchronous motor at the rear. Together they produce up to 390kW of power and 690Nm of torque.

This gives the flagship grade a 0-100km/h sprint time of just 4.5 seconds. There’s obviously ample power to be had here which will delight EV fans who like that tummy-falling sensation when accelerating.

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.

The Sealion 7 Performance has a blade battery with a large 82.56kWh capacity which supports a 456km WLTP driving range. This isn’t terrible for city drivers but a regional driver will likely want a longer range. BYD includes a portable charging cable with the model.

Charging is sorted via a Type 2 CCS charging port which accepts up to 11kW on an AC charger and up to 150kW on a DC charger. On a 150kW DC charger, you can go from 10 to 80 per cent in as little as 32 minutes and that increases to more than eight hours on an 11kW AC charger. All of the figures are quite good and help with the general day-to-day convenience.

The official energy consumption figure is 20.4 kWh per 100km but after doing a healthy mix of open-road driving and city stuff, my average has popped out at 19.1kWh. I reckon it's a solid result for a ‘performance’ grade but I didn’t find the regenerative braking to be particularly strong on this model.

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.

The Performance grade offers plenty of power that is delivered wickedly quick without feeling overwhelming when you have to accelerate. You still feel in control, which is very important when you have outputs like this does.

The steering is responsive and light enough for quick lane changes. The general on-road handling is quite refined but there is more roll in corners than you’d expect and this is the only time the power can make the handling feel a tad wobbly.

Surprisingly, there isn't a one-pedal function and the regen braking isn’t particularly strong. It’s difficult to ‘creep’ forward in this in stop/start traffic where it can feel a bit jerky at times, so it handles best on the open road.

Visibility is mostly good but the rear window is narrow and a digital rear-view mirror would have been welcomed in this model. Suspension is sports-firm but forgiving over bigger bumps. 

The 360-degree view camera and surrounding sensors makes this super easy to park and honestly, you shouldn’t have any trouble manoeuvring the Sealion 7.

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.

The Sealion 7 is covered by a six-year/150,000km warranty which is good for the class. The battery is covered by an eight-year/160,000km warranty which is a normal term.

The Sealion 7 gets a 10-year capped price servicing but it’s expensive compared to some of its peers at $4157.

Servicing intervals are spaced at every 12 months or 20,000km, whichever occurs first.

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.
