Jaecoo J7 vs BYD Sealion 5

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.

Cars that don’t always appeal to enthusiast buyers are often seen by manufacturers as a way of not bothering with the dynamics. Good enough is, apparently, good enough. Thankfully, BYD hasn’t taken that path here and the local suspension tweaks have turned what could have been a me-too product into a bit of a dynamic class leader. And even if buyers can’t verbalise the benefits of that, they will still be subliminally enjoying them with every kilometre.

The other stand-out feature is the price-tag which represents an awful lot of car for the money. And, in such a price-sensitive market as this one, that will get the BYD over the line for a lot of families. That it also offers a vastly better driving experience simply makes the value equation – and the purchasing proposition – even stronger.

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 interior of the Sealion 5 feels pretty well-made and there are soft-touch surfaces on most of the touch-points. The steering wheel, too, is thick and chunky and nice to hang on to. But there’s a lot going on in terms of different colours, textures and surfaces, and it can all look a bit busy, despite the high-tech boardroom overall flavour. It’s also worth mentioning the trim material is synthetic but does a great job of looking and feeling like real leather.

Externally, there’s not a lot to grab the eye. Sure, it’s not an unpleasant looking vehicle, but neither does it stand out from the mid-size SUV pack. At least BYD decided against those cheap-looking plastic tack-ons on each wheel-arch.

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.

Here’s the other big shock relative to the price-tag of the Sealion 5: This is not a small car. Based on the price, you might have been thinking the vehicle would be a compact SUV. And you’d have been wrong. This is a proper mid-sized SUV with room for five and luggage and an overall length of 4.7 metres and change. And to put that into some kind of perspective, that’s just 30mm shorter than the Sealion 6 which costs about $9000 more at its starting point.

The wheelbase is long, too, and the 2712mm between the axles helps make the interior even more spacious. That means there’s lots of stretching room in the front, but also that a grown adult can comfortably sit in the back seat behind another grown adult at the wheel and still have enough room in every direction. The window sills are commendably low in the rear seat, too, ensuring even littlies can see out.

The biggest problem in the back is that the seat cushion is a bit flat, but, like the front chairs, it’s still pretty plush.

With all five seats in place, the Sealion 5 boasts 463 litres of luggage space and the cargo area is well done with storage pockets at each side, a light and an under-floor tray designed to transport charging cables and a tyre repair kit. Yep, that’s right, there’s no spare tyre of any sort here. No surprise, really.

Fold the rear seat down and you’re suddenly looking at 1410 litres of cargo space and your SUV is now a panel van.

As well as the dual-zone climate control, the Sealion 5 also offers a single USB -C and a USB-A charging port in the front and rear compartments.

The Sealion 5 also offers a V2L (Vehicle to Load) function, meaning it can power camping or on-site work equipment and even act as your home’s battery.

The plug-in hybrid in question is the BYD Sealion 5. It has a claimed EV-only range of better than 100km, relatively quick charging, a decent sized battery, adequate performance, enough interior space for a family, good safety and lots of equipment. Oh, and it costs just $33,990, before on-road costs, in its entry-level Essential form. Incoming!

Equipment-wise, that sub-34K sticker gets you a 10.1-inch central info-screen, an 8.8-inch driver display, digital radio, a six-speaker stereo, wireless connectivity for Android Auto and Apple CarPlay and dual-zone climate control.

Throw another four grand on the table and you move up to the Premium version which adds plenty of kit for the $37,990 ask. That includes a panoramic sunroof, automatic tailgate, roof rails, heated and electrically folding mirrors, one-touch power windows, a six-way powered drivers seat and four-way powered co-pilot’s chair, a heated and ventilated driver’s seat and wireless charging.

The step up from Essential to Premium also includes a battery upgrade, and we’ll cover that off in the Under the Bonnet section below.

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.

Both variants of the Sealion 5 have the same driveline – mostly. They each use a 1.5-litre petrol engine teamed with a single electric motor, both driving the front wheels. Unlike the bigger Sealions, there’s no all-wheel drive version. Power peaks at 156kW and torque at 300Nm.

Why a non-turbocharged engine? BYD tells us the non-turbo engine helps keep cost out of the vehicle and, since the engine really only runs to power the electric motor and charge the batteries, it does so at a relatively constant engine speed, negating the need for a wide spread of petrol power.

The only major difference is that the Essential version has a 12.9kWh battery-pack, while the Premium gets a bigger, 18.3kWh pack for longer range, but precisely the same output and, therefore, performance.

A single-speed transmission is part of the BYD driveline package, also made possible by the fact that the vast majority of the driving of wheels is done by the electric motor.

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 Premium’s bigger battery claims to up the official NEDC range from the Essential’s 71km to 100km. BYD reckons with the 52-litre fuel tank brimmed and the car operating at its claimed 1.2 litres per 100km efficiency, the range of either version is just on 1000km. In the real world, that’s likely to be closer to 800km (especially with some highway running thrown in) but it’s still one heck of a solution to range anxiety.

There’s no DC charging function for the Sealion 5, so forget about commercial fast chargers. But on a 3.3kW AC power outlet, the maker claims the Essential can reach full charge in under four hours, while the Premium’s bigger battery will take under six hours to fully charge. A Type 1 charge cable is included.

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.

You don’t have to drive very far to realise that the local input into the Sealion 5’s suspension and steering have been worth the effort. BYD Australia has a local engineering team on call these days, and it shows here.

Actually, the steering is not the highlight; it has some weight but not a whole lot of feel, or, indeed, feedback for the driver. The ride and handling combination is what stars. Obviously well-damped, the suspension allows for a ride that is both complaint and quiet, without causing the car to wallow around like some jacked-up designs can with their higher centre of gravity.

In fact, the BYD is athletic to the point where keener drivers will find it an entertaining drive; hardly something that can be said for the majority of medium SUVs.

Performance is strong without being overwhelming and even though the Sealion 5 has that signature electric-drive feeling of effortlessness, the accelerator pedal has been calibrated to avoid the neck-snapping surge of grunt off the line. As such, it emerges with a fairly flat acceleration curve, and no hint that the petrol motor is cutting in or out.

Until, that is, you bury the throttle all the way at which point the petrol engine takes a few second to join in. And when it does, it’s pretty vocal – shrill, almost – as it catches up with the rest of the car and starts directly driving the wheels. To be fair, though, this is not going to be a common occurrence in everyday life thanks to the flexibility of the petrol-electric system for 99 per cent of circumstances.

On the move, the cabin is perhaps most notable for its soft, plush seats that are a nice change from the church pews of some manufacturers. And although the driving position is about right, taller drivers might prefer a steering column that extends out another few millimetres.

The driver display screen is another source of annoyance. It’s pretty small and contains lots and lots of information, to the point where the typeface is too small to be read on the run by anybody who relies on reading glasses.

Passive safety in the Sealion 5 starts with no fewer than seven airbags including full-length side-curtain bags. 

There’s also a front-centre airbag, something we’d like to see in more cars, particularly at this price-point. Child restraint points in the rear seat are the ISOFIX type.

The BYD gets pretty much the full suite of driver aids, including autonomous emergency braking, blind-spot monitoring, rear-cross traffic alert with active assistance, stability control, active cruise-control, traffic-sign recognition, front and rear collision warning and tyre pressure monitoring.

The Sealion 5 also incorporates a driver-attention monitor which seems better calibrated than some earlier efforts from some of the Chinese carmakers. Also improved in calibration terms is the lane-keeping assistance which is still too violent for our tastes, but more subtle than some of the competition’s systems. But while the savagery of this system has been toned down, it appears to have been at the expense of sensitivity and, time and time again, the cameras missed road markings that were faded or dirty.

The major safety benefit in paying more for the Premium variant is the addition of front parking sensors and a 360-degree camera instead of the Essential’s simple reversing camera.

The Sealion 5 has not been ANCAP tested as yet, although BYD says this is largely down to ANCAP’s scheduling rather than any hesitance on BYD’s part.

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.

Like other BYDs, the Sealion 5 comes with a six-year/150,000km warranty. Some of the competition have unlimited kilometre warranties, but to be honest, 150,000km in six years is going to be beyond the need and aspirations of most owners.

The EV battery is covered by an eight-year/160,000km warranty, and let’s not forget, BYD was a battery manufacturer before it started making whole cars. Certainly, the company is very bullish about the quality and safety of its 'Blade' battery technology, claiming it easily passes the technically-daunting 'nail-puncture' test.

BYD plans to have capped-price servicing for the Sealion 5, but no pricing announcements have been made yet.

Servicing also falls into line with other BYD models, so that means 12 months or 20,000km intervals.
