Jaecoo J7 vs BYD Seal

What's the difference?

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.

Those big auto executives have good reason to be worried, because the Seal is yet another impressive offering from China’s most formidable EV player.

It’s not perfect. In some ways it’s trying too hard to be a luxury car, and I think the software in particular could use a little work, but the Seal just does so much right I think it will be hard to be disappointed with one, particularly given its keen entry price.

In fact, if we had to pick one from the range, it would probably be this mid-spec Premium. The range and power on offer are stellar, and all for less money than an entry-level Model 3 or Polestar 2.

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 Seal looks great. It’s about as modern a take on the traditional three-box sedan as you can get. It’s low-slung with curvy lines and a sporty overall feel.

The design touches, like the headlight and DRL surrounds, side skirts, and wheels are maximalist compared to the minimalist vibes of the Model 3 and the Polestar 2. But I don’t necessarily think that's a bad thing as it offers buyers a genuine alternative.

I also like the way the brand has executed the LED lights and particularly the tail-light fittings. There’s also an admirable restraint when it comes to badging compared to a lot of this car’s Chinese rivals. It doesn’t give off the vibe of a cut-price product at all.

Inside there are elements which are appealing, and some things which fall short. First up, I do think the Seal wears its influences throughout the industry on its sleeve a bit.

The digital dash cluster theme, for example, seems to (poorly) emulate the Mercedes-Benz software, the little plastic crystal shifter piece on the inside seems to have been overtly influenced by a similar (actual crystal) piece available in Volvos, while the centre screen and dual wireless phone chargers are pretty obviously BYD’s take on the similar bits available in the Model 3.

Maybe in this sense, it’s trying a little too hard to be a luxury car and a tech-heavy electric vehicle, with items which aren’t quite up to the same quality (particularly the software). But then, it all works well enough, and can you complain at the price?

One thing I think BYD gets right though is the level of comfort on offer in the cabin and the clever little styling bits which remind you of its namesake.

The door handle pieces and integrated speaker bits are shaped like a Seal flipper. As are the dash-mounted air vents, and if you look closely even the plastic garnish on the steering wheel looks a bit like a top-down cross section of the animal.

I like it because its subtle rather than in-your-face as some of the Atto 3's design elements are.

The quality is also up to muster, big time. There wasn’t a creak, groan, or rattle from this car’s interior in my entire time with it, including on some of Sydney's worst roads. And the seats, which are designed like absolute thrones, are clad in lovely soft leather. You sink into them. Even the two-tone Alcantara finish through the doors and centre console is thoughtfully placed.

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.

The Seal has a huge cabin, and in a lot of ways it feels like the large sedans of old. You can sit nice and low in the cabin, and there’s heaps of knee and headroom thanks to its width.

Soft-clad materials for resting your knees and elbows on go a long way towards keeping this car comfortable on longer journeys, and the presence of a digital dash and a holographic head-up display is nice to have compared to the bare-bones dash of the Tesla Model 3.

The wacky rotating central touchscreen feature makes an appearance from other BYDs, but again, it’s a bit silly and I’m not sure how much use you’ll get out of it. Even Apple CarPlay only works in landscape mode, so I didn’t find it useful.

Practicality features are abundant, with a large bottle holder in the doors, and two more in the centre console. One even has a floating floor, so you can push it down to accommodate large bottles if need be.

Dual wireless chargers are always a nice touch, and the bridge-style console has a large pass-through storage area underneath, which also hides the USB-C, USB-A, and 12V outlets. The armrest console box is nice and deep, too.

The back seat is enormous. Possibly one of the largest spaces in this segment. It comes at a cost to boot capacity, but your rear passengers won’t want for space no matter how tall they are.

At 182cm tall I had leagues of airspace behind my own driving position, and the wide cabin, accommodating seats, and flat floor mean the centre position is even useful for a full-sized adult.

Storage comes in the form of three pockets on the back of each front seat, a large bottle holder in the doors, two cupholders in the drop-down armrests, a small tray on the back of the centre console, and a small flip-out cover which reveals a USB-C and USB-A charging port for rear passengers. The rear seat even gets dual adjustable air vents, but no third climate zone.

The massive fixed glass roof looks the business and keeps the cabin airy, just like in the Model 3 and Polestar 2, but I find these big glass fittings tend to cook interiors in the Australian sun.

BYD tells us the tint is so heavy it has a ‘solar transmittance’ of just 16 per cent, but 16 per cent is still a lot in Australian summer. Thankfully, unlike its two rivals, BYD ships the Seal with a fold-out cover screen as standard.

Remember how I said the massive rear seat comes at a cost to boot space? At 400 litres the Seal’s boot is a bit compact, made worse by the fact it’s a sedan and not a liftback, so the access area is a bit narrow.

It could only fit the largest CarsGuide luggage case alongside the smallest one, but not all three including the medium case. This could be a blow to family buyers who need to fit a pram alongside other things.

Under the floor there’s an extra space great for the storage of your V2L adapter and AC charging cable, but there’s also only a tyre repair kit and no spare.

Just like its Model 3 rival, the Seal arrives in Australia in three variants - the base Dynamic, top-spec Performance, and the one we’re looking at for this review, the mid-spec Premium.

Price is, of course, BYD’s forte, with this mid-spec Premium (equipped with a long-range battery) even managing to undercut the entry-level Model 3 RWD.

Before on-road costs and state-based incentives you can have one of these from $58,798, while (at the time of writing at least) the enormously popular Model 3 RWD weighed in at $61,900. Its next closes rival, the Polestar 2 Standard Range, costs from $67,400, so value here is obvious.

The Premium’s long-range battery allows a WLTP-certified driving range of 570km between charges which is even one of the longest cruising ranges available on any electric vehicle in Australia right now.

The list of standard features is exhaustive, including 19-inch alloy wheels, LED headlights, a massive 15.6-inch multimedia touchscreen with wired Apple CarPlay and wireless Android Auto, a 10.25-inch digital instrument cluster, a holographic head-up display, dual wireless phone charging bays, built-in navigation and connected services, ‘genuine’ leather seat and wheel trim (a blend of synthetic and real leather), an eight-way power-adjustable seat for the driver, ventilated and heated front seats, dual-zone climate control, a fixed panoramic glass roof and keyless entry with push-start ignition.

The Seal also gets an impressive array of standard safety kit. More on this later.

The only options are premium paints and an alternate light blue theme for the interior which cost $1500 each.

This list of kit would even be impressive on a combustion car at this price, so the fact it’s also electric and offers one of the longest driving ranges on the market is a bonus.

The one area where I think it lacks a little is the stock software. It looks okay and, to be fair, functions a lot better than its Chinese contemporaries and even some other brands, but once you dig into it a little there are some clumsy menus, and it becomes painfully obvious it’s a simple Android reskin. A swing and almost a miss for something so integral to a car like this.

Why is it called the Seal? Well, in BYD’s home market of China, its range is so expansive it has split it up into two model lines, the Dynasty series (named after historical Chinese kingdoms) of which the Atto 3 is a member (it is called the Yuan Plus in China), and the Ocean series which the Seal and Dolphin belong to. The next BYD to arrive in Australia, a mid-size SUV likely to be called the Seal U, also belongs to the Ocean series.

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.

Each Seal variant gets its own drivetrain outputs, and the mid-spec Premium drives the rear wheels with a 230kW/360Nm electric motor via a reduction gear.

On paper, it’s slightly more powerful than the Model 3 RWD, with more power and less torque than the Polestar 2 Standard Range.

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.

Providing power is a sizable 82.56kWh lithium-ion battery pack, using BYD’s signature weight and space-saving ‘Blade’ form-factor, and the more affordable LFP (lithium iron ferrophosphate) chemistry.

On the charging front, the Seal Premium can top up at 150kW on a DC unit (using a Type 2 CCS connector) for a 10-80 per cent charge in roughly 40 minutes, while on AC its a disappointing 7.0kW.

The 7.0kW inverter means it’s hardly worth plugging the Seal in at a slow public charger when you visit the shops, as you’ll only get about 50km of range an hour. It’s for this reason most cars with batteries this size have 11kW inverters.

Unlike the Model 3 or Polestar 2, though, the Seal features a V2L system, allowing you to power household appliances from its Type 2 charging port.

Claimed energy consumption for the Seal is 14.6kWh/100km which is low, and about what we were seeing on test. It’s a little hard to tell because the trip computer only offers total consumption over the entire life of the vehicle, or for the last 50km, but not for a set trip interval. Weird.

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.

I wasn’t expecting the Seal to impress me particularly. After all, it’s in this segment against tough competition, amongst recently updated versions of the Model 3 and Polestar 2, and while the previous BYDs I’ve driven have been a cut above their Chinese contemporaries, they also haven’t done a lot to stand out from the crowd.

Clearly, though, BYD has something to prove with its sporting sedan and the Seal is immediately impressive. The cabin is quiet and refined, the seating position is great it's smooth from take-off.

The steering has an artificial tinge to it removing a bit of feedback from the road, but proves at least quick and accurate at speed, and the handling is superb.

I kept pushing the Seal in my test drive, expecting gnarly characteristics to surface but they didn’t. This sedan grabs onto the road with excellent control and traction at the rear, spurred along by its long wheelbase, and improved tyre choice (Continental rather than the sub-par Chinese rubber worn by the Atto 3 and Dolphin).

While on paper it appears to have at least comparable motor output figures to the Polestar 2 and Model 3 - the Seal Premium doesn’t quite feel as rapid, its electric motor having a more relaxed vibe and responsiveness when you stomp on the go pedal.

This can be tweaked a little by dialling it up to Sport mode, and while it still doesn’t feel quite as breakneck fast as the Model 3, in particular, it’s plenty to be going on with.

The most impressive part of the Seal drive experience, though, is its ride. Ride is a constant problem for EVs as manufacturers go to lengths to tame the additional weight of batteries, but the Seal is the most impressive in its cohort, and by quite a margin.

It’s firm enough to be controlled, but has a lovely soft edge to it, so larger bumps, frequent corrugations, or sharper road imperfections don’t ruin your day.

The Model 3 and Polestar 2, even in their improved forms, are not this good. In a lot of ways the Seal’s suspension tune reminds me of the Mustang Mach-e. It has a soft edge, offset by a bit of secondary jiggle as the car settles, which is its only real blemish.

The Seal has no right being this good. It’s now not just matching its far more established rivals but doing some things significantly better.

The Seal has an extensive list of today’s active safety equipment, including auto emergency braking (front and rear), lane keeping aids, blind-spot monitoring, rear cross-traffic alert, adaptive cruise control, traffic sign recognition and driver attention alert.

For the most part, these systems aren’t invasively annoying, which can’t be said for many products from rival automakers.

However, the traffic sign recognition and overspeed warning system conspire to intrude with constant beeping.

Mercifully, and unlike the equivalent system in Hyundai products, it’s a distant beep, but a consistent one nonetheless, as the traffic sign system frequently picks the wrong speed for whatever reason, and then chastises you for going over it.

Also, the adaptive cruise control system can’t hold a candle to the Model 3's. The system in the Seal amounts to the usual sort of adaptive cruise in most other cars, whereas the one in the Model 3 (regardless of how you feel about the brand’s outrageous claims) is properly next-level in its lane keeping and distance controls.

The Seal is equipped with seven airbags and was rated a maximum five ANCAP stars to the 2023 standards.

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.

The long-term ownership aspect for a BYD product is still a bit of a mystery as the current crop of cars have only just landed in Australia in the last year or two, but if it offers you any peace of mind, the Seal is covered by a six-year/150,000km warranty with a separate eight-year/160,000km warranty for the battery pack.

In order to avoid having to have a traditional dealer network, BYD has partnered with MyCar to fulfil servicing. Visits to one of these locations is required once every 12 months or 20,000km whichever comes first, and pricing is fixed for the first eight years, working out to an annual average of $299.
