What's the difference?
Following the money comes pretty naturally to carmakers. It’s what happens when the product planning department smells a new direction on the breeze and then handballs that to the design and engineering folks who turn a perceived market trend into a showroom reality. And when everybody gets it right, you have a new default product. And everybody else has to keep up. Some even have to catch up.
We’ve seen it plenty of times before, too. Think about those early 1980s days when the default small car went from a sedan to the five-door hatchback. Didn’t that catch on? You might also remember more recently when a family car had to be a four-wheel drive. And what about the dual-cab ute revolution of the last 15 years?
The other strident market segment right now is the SUV, of course. And within that, most recently has been the march to electrification, starting with conventional hybrid technology and now progressing to the new must-have, a plug-in hybrid platform.
The fact is, if you’re a Chinese carmaker intending to sell on a world stage, you can’t ignore the plug-in SUV in any of its various sizes and marketing segments. There’s a good basis for this, too. Plug-in hybrids just make good sense. They offer the urban running-cost advantages of any hybrid, the option of zero tailpipe emissions, all-electric running over a normal commuting distance and – crucial for a big country like this one – they’ll keep motoring along for as long as the owner puts petrol in them.
Okay, so they can be heavy with all that tech on board, and there’s no denying that two power sources (petrol and electric) make for a more complex machine, but the advantages outweigh the downsides for many buyers.
The other graph you can plot with great certainty is that new tech will get cheaper as the industry moves forward. Which is exactly where BYD finds itself right now by being able to offer a plug-in hybrid variant of its Sealion 5 mid-sized SUV at a price that will have much of the opposition running scared. But how scared should the others be?
Looking across BYD's line-up, you'd think you were reading the attractions for the local aquarium! And now the Sealion 7 has entered the splash zone, or more accurately, the most popular car segment - the mid-size SUV.
It fights for pole position against the long-running electric favourite, the Tesla Model Y but newcomer Cupra Tavascan also offers some sporty competition.
For this review we're testing the flagship Performance grade to see whether or not it offers family-friendly fun.
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 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 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.
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.
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 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.
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.
The Sealion 7 is being offered in only two grades, the base Premium and the flagship Performance that we're testing for this review.
There are only four points of difference between the two grades. The Premium isn't all-wheel drive and doesn't include heated rear outboard seats, a heated steering wheel or dual electric motors like the Performance gets. That creates a $9K price hike to jump into the top-spec grade, bringing it to $63,990 before on-road costs.
It might be starting to sound expensive but it's still more affordable than most of its main rivals. This is because the Cupra Tavascan VZ is priced from $74,490 MRSP and the outgoing pre-update Tesla Model Y Performance comes in at $82,900 MSRP.
What do you get in the Sealion 7 Performance? A lot, it seems. Standard equipment includes electric front seats with heat and ventilation functions, adjustable under-thigh and lumbar supports, panoramic fixed sunroof and leather upholstery, a leather-wrapped steering wheel with mounted controls.
Technology looks top-notch with a crystal clear 360-degree view camera system, a rotating 15.6-inch multimedia system, 10.25-inch digital instrument cluster, coloured head-up display, dual-zone climate control, two USB-A and -C ports, 12-volt socket, V2L capability (via adapter), wireless Apple CarPlay and Android Auto, 12-speaker Dynaudio sound system, over-the-air updates, and satellite navigation.
There's also keyless entry and start, powered tailgate, BYD digital key (via smartphone app), tyre repair kit, rain-sensing wipers, dusk-sensing LED headlights and soundproof double glazed glass on both the windshield and front windows.
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 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.
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.
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.
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.
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.
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 new Sealion 7 has a maximum five-star ANCAP safety rating from testing done in 2025 and scored well across its individual assessment criteria, scoring 87 per cent for adult protection and 93 per cent for child protection, respectively.
The Sealion 7 features nine airbags, including side chest airbags for both rows but it’s common to see these just on the front, so this is excellent.
When it comes to standard safety equipment, it's almost a case of what doesn't it have? Some stand-out features include front and rear cross-traffic alert, blind-spot view monitor (which pops a video feed of your left blind spot onto the multimedia display) and child detection alert.
Other standard features include lane keeping aid, lane departure warning, adaptive cruise control, forward collision warning, rear collision warning, driver attention monitoring, 360-degree view camera system, and multiple parking sensors.
The autonomous emergency braking has car, pedestrian, motorcyclist and cyclist detection. For pedestrian, motorcyclist and cyclist detection, it is operational from 8.0 to 80km/h. For car detection, it is operational between 4.0 to 150km/h.
There are ISOFIX child seat mounts and three top-tether anchor points and the rear row is wide enough to accommodate three child seats side by side.
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.
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.
