BYD Seal 6 vs BYD Sealion 5

What's the difference?

The 2026 BYD Seal 6 proves a compelling offering at a time when cost and efficiency should be nearer the top of your new car consideration list. Not just for its long range, but its clever use of electrons and fuel to keep costs down even after the initial humble outlay.

It helps that the Touring Premium remains sub-$40,000, before on-roads, and offers plenty of features, a spacious interior and the right kind of drivetrain for everyday use in Australia.

While rivals like the Toyota Camry or Skoda Octavia are more polished and can almost compete on price, the BYD’s features and efficient PHEV powertrain will outweigh the brand names and more refined on-road behaviour of established rivals for, we would guess, a significant number of buyers.

While the BYD Sealion 5 lacks the polish of some more established plug-in hybrids, it has a seriously compelling price advantage over some competitors. It makes a base-model Mitsubishi Eclipse Cross PHEV feel positively outdated and it’s $13,800 cheaper.

BYD's lack of ANCAP rating for the Sealion 5 and the uncertainty around it still being a new brand are downsides, even if BYD is quickly moving past the latter. But being the most affordable PHEV available while having this much showroom appeal is bound to work in the Sealion 5’s favour, just don’t expect a dynamic masterpiece once you’re out on the road.

The Seal 6 Touring might be BYD’s best-looking car. It boasts a handsome wagon shape and its features don’t overdo the brand’s aquatic design language.

It’s not fussy with too many elements, but it’s not anonymous like some designs from China can seem on Australian roads. It’s definitely a BYD, but it’s not shouty about it. This means it should, visually at least, appeal to buyers who just want a sensible-looking sedan or wagon. Watch out again, Toyota.

The tail-lights and lower trim at the rear don’t leave too much blank space and the whole shape of the rear is sleek enough without cutting too far into the boot space.

Inside, the Seal 6 looks ‘classic BYD’, which isn’t a bad thing, but it’s not enormously interesting. It’s got enough points of difference from the layout Tesla has popularised and many Chinese brands now default to, but some daring style elements wouldn’t go astray.

The BYD Sealion 5, from the outside, is inoffensive but also uninspiring. That’s likely not such a bad thing for a mid-size SUV – it’s rare you’re hearing someone talk about how beautiful the Mazda CX-5 or Toyota RAV4 is. 

Its quartet of colour palette options comes in on the safe side, too. Aurora White is standard, Atlantis Grey, Harbour Grey and Cosmos Black are cost-options.

Our test car is Atlantis Grey, which is interestingly quite blue. 

The relatively upright shape is a slight departure from the more ‘aquatic’ silhouettes of BYD’s line-up, but the front grille and light layout are decidedly in step with the brand’s oceanic design language. There’s a bit going on, you could say.

The slimline tail-lights are the rear, especially from a three-quarter angle to the side, look attractive and help break up the rear without looking messy.

The Sealion 5’s design is overall net-good, but it’s inside where the mid-sizer feels like you’re getting plenty for your dollar.

The seats, despite the leather fakery, feel like decent material, and the layout uses buttons and physical controls cleverly without feeling outdated.

When it comes to practicality, a long trip will reveal plenty of things you might not notice day-to-day. Things like whether the seats really are comfortable, or how useful the cupholders are for different vessels.

Fortunately, the BYD Seal 6 holds up rather well in a few key areas.

Its seating adjustability and the seat itself are comfortable and easy to find the right driving position for an average-heighted man (me), though the bolstering on the seat won’t hold you in place tightly during spirited cornering.

The wheel is nice to hold and it’s easy to feel your changing position while steering, and the controls on it are clear, though more physical controls in the rest of the cabin would be an improvement.

The Seal 6 suffers from a reliance on the touchscreen that a number of car brands’ head designers and engineers are moving away from. The software’s menu system is not quite up to the task of being the only point of contact for functionality, as it requires scrolling through and can be distracting on the road. That will set off the driver monitoring, by the way.

Wireless Android Auto or Apple CarPlay and a wireless phone charger (which is out of the way) provide a good workaround and ensure your phone doesn’t die on a long journey.

There’s storage under the centre console where the cupholders are, a nice spot to keep things out of the way, plus there are USB-A and USB-C ports down there.

Behind the front seats, the second row isn’t lavishly spacious but allows a 178cm adult to sit behind their own seating position with kneeroom, headroom and shoulder room to spare. The sunroof makes it quite nice and light back there, too.

The second row seats fold down 60/40 to turn what was a 670-litre boot into a 1535L boot, though that seems to be measured to the roof rather than the tops of the seat-backs.

There is, disappointingly, no spare tyre under the boot floor, just a repair kit. I’d want a space-saver at least if I was travelling interstate (without a launch event support car).

To actually interact with the interior is, at times, another story. BYD’s tech interface is generally easy to manage, but could be simpler when it comes to navigating menus for the sake of driver distraction.

While larger text and buttons would be welcome, the multimedia system is easy to use when parked, and the functionality is impressive for the price point.

Winning more points for the Sealion 5, though, are the physical controls – buttons and the traditional gear selector – which make the cockpit much more intuitive while on the move.

Ergonomically, though, the adjustment between the steering wheel and driver’s seat could do with some work, as I found it difficult to find a truly comfortable driving position. This is coming from someone 178cm tall, a very normal height in Australia.

Better adjustability on the steering column would be helpful, as it’s something I’m not sure I’d ever get totally used to.

Visibility and physical space inside the Sealion 5 is impressive, though. The car is 4738mm long, 1869mm wide and 1710mm tall, and the roof and window lines don’t swoop too aggressively towards the rear.

There are low window shoulders even into the rear, so light isn’t at a premium, though under-leg support could be better on the pew.

It’s otherwise un-cramped. The 2712mm wheelbase means decent legroom for second-row folk, plus behind the 60/40 split-fold seats there’s 463 litres of space for luggage. That becomes 1410L with the seats folded.

There’s unfortunately no spare tyre, just a tyre repair kit.

The BYD Sealion 5 Essential kicks off from $33,990 before on-road costs, four big ones less than the Premium ($37,990). We’re focusing on the Essential today, but don’t think that means a shallow list of features.

As you’d expect from BYD if you’ve been paying attention to the Chinese brand in its emergent years, the Sealion 5 comes with more than $34K would normally get you – a 10.1-inch central multimedia touchscreen, an 8.8-inch driver display, synthetic leather upholstery, dual-zone climate, a six-speaker sound system, wireless Android Auto and Apple CarPlay, USB-A and -C ports front and rear, digital radio and keyless entry.

On the outside, LED headlights and tail-lights are the same for both variants.

Both also have 18-inch wheels, not unwelcome for the benefits of on-road comfort.

Consider that the most popular SUV in the country, the Toyota RAV4, costs at least $45,990 without the benefit of a plug-in drivetrain (yet) and comes with, on paper, a more sparse list of features.

The closest PHEV competitors are still more pricey, including the Geely Starray ($37,490) and Chery Tiggo 7 ($39,990), and arguably lack the brand power BYD has come to enjoy.

The BYD Seal 6 has a 1.5-litre, four-cylinder petrol engine that helps a front-mounted electric motor drive those two wheels.

While the engine’s outputs are 70kW and 120Nm, the electric motor does the bulk of the work, with its 160kW and 260Nm outputs.

As such, the Touring we’re driving on this trip has total outputs of 163kW and 260Nm, with a claimed 0-100km/h time of 8.1 seconds feeling about right despite a peppy enough take-off from standstill.

The Seal 6 Sedan by comparison has the same engine but a less powerful electric motor, resulting in total outputs of 130kW and 210Nm.

The Sealion 5’s front wheels are driven by a combined maximum of 156kW thanks to a 1.5-litre four-cylinder petrol engine (145kW/300Nm) and a permanent magnet synchronous motor (72kW/122Nm).

BYD claims a 0-100km/h sprint of 7.7 seconds for the Sealion 5 Essential, four tenths faster than the Premium despite only a 61kg difference in kerb weight.

While the efficiency of a new car is sometimes difficult to test on a launch driving program due to car-swapping and unusual driving conditions like filming or dynamic testing, the car we drove for the full two-days was the same one, and only used for the journey.

That means its full trip of 996.3km (frustratingly not officially the 1000km promised) is a faithful example of what an interstate trip might mean for one or a couple of travellers.

Officially BYD claims a 0.8L/100km figure under NEDC testing for the Touring, but tests like those are misleading for plug-in hybrids as the battery does a lot of lifting.

So BYD tested before this event the claim it could drive a Seal 6 from Sydney to Melbourne, then double-checked it.

But Sydney to Melbourne on a single tank and a single charge turned out to be accurate, even after running down a significant chunk of the Touring’s claimed 100km of electric range as tested under WLTP conditions.

Unfortunately we couldn’t verify the total fuel used over the 996.3km traveled in car number four without first checking the tank was properly full and then refilling it again at the end.

Given the car estimated 68km left in the tank at the end of the trip, you could assume a fuel consumption reasonably below 6.5L/100km given the 65-litre tank still had some juice after near-1000km.

The trip computer’s claim of 4.5L/100km as an apparent cumulative total (including the several hundred kilometres of running-in before the launch) seems fair with a few extra battery charges under its belt prior to the drive.

Charging maxes out at 27kW on DC, or 6.6kW on AC by the way. DC charging should take less than an hour for the Touring’s 19kWh battery.

With a charged 12.9kWh lithium iron phosphate (LFP) battery and a full 52-litre (95 RON minimum) fuel tank, BYD reckons the Sealion 5 Essential can cover 1001km under NEDC testing, which is optimistic. It claims 71km can be done on EV power alone.

Not only due to the lenient nature of NEDC testing (WLTP is more common and usually results in lower ranges), but the reality is that once the battery is flat, the engine is doing a lot more work.

Charging is slow, limited to 3.3kW (AC only), which should take between 4 and 5 hours to charge from the lower end of the gauge for the battery size. Given most PHEV owners will do this overnight at home, that’s certainly not the end of the world.

Claimed consumption figures are 1.2L/100km with more than 25 per cent battery charge, or 4.5L/100km when it dips below that.

Realistically you could do sub-50km trips and use no fuel, or never plug your Sealion 5 in and see fuel consumption soar. In any case, anything close to 1001km in a single run is extremely unlikely.

If I had to buy a BYD today, the Seal 6 Touring makes a very strong case for itself in many ways. But unlike some of its stablemates, the way it drives is one of those ways.

The first day (of two) on the local launch saw a drive from Sydney to Albury on the Hume Highway, not known for being particularly dynamic. But the Seal 6’s relatively compliant suspension and lack of roaring road noise was welcome, at least for sections you couldn’t otherwise blame on the road’s surface.

The second day through some of Victoria’s high country and past Lake Eildon allowed the Seal 6 to prove it’s not a slouch, though calling it a sports car would be a stretch. Instead, the Touring's powertrain tune and apparently well-adjusted suspension and chassis meant spirited driving around twisting mountain roads and through winding backroads was easy, if not always exciting.

Big bumps would sometimes unsettle the Seal 6, but its predictability in most cases makes it feel safe and planted. The steering feel isn’t sportscar-like, but doesn’t leave you guessing and the same goes for pedal inputs.

I do wish the Seal 6 was a little more eager, but it’s not disappointing off the line and certainly has enough pep for daily duties.

There are drive modes, Eco, Normal and Sport plus a Snow mode, though the difference between the three doesn’t seem to be enormous. Eco definitely does what it says on the tin, though. The two regenerative braking levels also don’t seem to be incredibly different.

Also a let-down is the eagerness of the driver monitoring to direct your attention back to the road. When the ADAS (Advanced Driver Assistance Systems) settings were all active I started to tune the monitoring chime out because it would sound with every look at the multimedia screen.

You might expect a car at this price, regardless of its drivetrain, to be underwhelming from behind the wheel.

That, then, makes it even more pleasantly surprising that the BYD Sealion 5 is actually rather competent. Not massively exciting or dynamic, but certainly not a disappointment.

The Sealion 5 is, save for a couple of arguably minor annoyances, quite easy to get used to and drive.

Firstly, when making proper use of its electric power, the drivetrain provides enough shove for its intended use. It’s not overly powerful, but you won’t have trouble overtaking. It’s the same with most of the inputs, the steering is light but not completely numb – again about right for how the Sealion 5 will be driven.

Perhaps its biggest departure from expectations based on other cars from China is its suspension is on the stiffer side of things, but again it’s not unruly or too rugged. In fact, it does provide a better sense of control than many of its compatriots.

Again, the biggest issue with the Sealion 5 day-to-day is its driving position, the steering column adjustment isn’t up to scratch and there’s not really a perfectly comfortable seating position (I’m a very standard 178cm).

On long trips, you might also find the engine gets quite noisy once the battery power is gone as it works hard to pull the mid-size SUV along under acceleration.

Its driver-assist systems are, you might be pleased to hear, on the calmer side of things – BYD is getting better at calibrating its safety features and I didn’t find myself rushing to switch it all off as quickly as usual.

It can still be a bit too persistent in its lane-keeping, but it’s a big improvement on the way things were.

There’s no ANCAP rating for the Sealion 5, but the list of safety kit isn’t lacking on paper.

BYD lists seven airbags ,including full-length side-curtain bags and an important centre airbag, plus there’s a whole suite of tech that’s, as noted, better behaved than past driver-assist systems from BYD.

The Essential only misses out on a surround-view parking camera and front parking sensors, both arguably important safety features for parents, but the rest of the list is the same as the Premium including adaptive cruise control, lane-keep and lane departure assist, traffic sign recognition, blind-spot monitoring, rear cross-traffic alert with rear AEB (as well as front AEB, of course) and tyre pressure monitoring.

BYD’s six-year/150,000km warranty is probably more than you’d need in terms of distance but is behind competitors who offer seven or eight years with unlimited kilometres, even 10 years conditional. An eight-year/160,000km warranty covers the battery, which is about par.

Finally, BYD has set servicing for every 20,000km or 12 months, with  the first five services totalling $2775, an average of $555 a visit. The fourth service is a hefty $1225, for reference.

BYD has more than 100 dealerships in Australia, with the brand still growing quickly.

BYD has a six-year/150,000km warranty, which is probably more than you’d need in terms of distance but is behind many competitor brands’ timelines – seven to 10 years is becoming the norm, even if it’s conditional.

An eight-year/160,000km warranty covers the battery, which is about par for the industry.

Servicing for the first five proper services ranges from between $285 and $930, plus there's a free check-up six months into ownership and a total cost over the span of $2355 – an average of $471 per service.

BYD has just over 100 dealerships in Australia, so finding one for servicing shouldn’t be too challenging.
