BYD Atto 3 vs BYD Sealion 6

What's the difference?

BYD hasn’t made dramatic changes to the Atto 3 for 2024, but has it done enough to lure in more buyers? 

The additional equipment, namely the larger infotainment screen and new tyres, will certainly help make the Atto 3 more appealing. And the technology behind EVs is more understood by the average motorists, so the barriers to making the switch to electrification are dropping.

But the single biggest factor is likely to be the price. At a time when inflation (and other reasons) is driving the cost of new vehicles up, having your updated model go in the wrong direction will only help make potential buyers take notice.

Especially when you consider Toyota’s closest rival to the Atto 3, the bZ4X, starts at $66,000, while the Tesla Model Y is priced from $55,900, making both significantly more expensive propositions. Heck, the cheapest Toyota RAV4 hybrid model starts at $42,260, only marginally cheaper than the Atto 3 Standard Range.

So, if BYD can make its value argument strongly it will help lure more new buyers to take the plunge into the world of EVs.

So, should Toyota, Tesla, Hyundai and others be worried about the arrival of the Sealion 6 and BYD’s new DMi powertrains? Yes, but not because it represents any major breakthrough in technology or dynamic prowess. 

Instead, the strength of the Sealion 6 is how average it is. It may not be the obvious class-leader in any particular area, but it does a good job in almost every measurable aspect and doesn’t possess any major flaws.

Yes, there are still questions about the long-term dependability of BYDs but that’s a risk any new owner will need to accept. But the very sharp pricing should tempt plenty of buyers to take that chance and continue BYD’s steady upwards trajectory in the Australian market.

In a couple of words, not really. At least when it comes to the exterior design.

In fact, the biggest design change for 2024 is actually the colour of our test car, the new Cosmos Black. Apart from that, the rest of the Atto 3 is unchanged visually, which is becoming something of a trademark for EVs, at least from newer brands like BYD and Tesla. 

Instead of worrying about adding a new grille, different headlights or an alternative alloy wheel design, brands like BYD are focusing on updating batteries, the technology and other software enhancements to keep their models fresh.

The only exterior change is at the rear, where the previous 'Build Your Dreams' lettering has been replaced by a simple 'BYD' badge.

As for the interior design, kudos to BYD for not following Tesla down the cost-saving-disguised-as-minimalist-design path, but personally the design aesthetic and the variety of colours and trims used aren’t to my taste, but I can see why others may love it. The ‘guitar string’ door pockets are likely a particularly polarsing design choice.

BYD has added a new interior option, with a black/blue trim for the examples finished with grey and black exteriors, while white and blue painted cars get a blue/grey interior.

This is one area where BYD has a mixed record. Not to be unkind or create an international incident, but the Chinese car industry has a history of not being totally original with all of its automotive designs.

However, things are improving and the Sealion 6 is a good example of the Chinese industry learning to develop its own style. While there are some subtle hints from European models, overall it’s a smart-looking mid-size SUV with some character to it - rather than being a bland imitation of something else.

One area where the Sealion is a cut above its competition is its size, being longer than and wider than the RAV4, Mitsubishi Outlander and Nissan X-Trail.

The Atto 3 remains classified as a ‘Medium SUV’ but blurs the line between mid-size and small in terms of dimensions, especially inside. It’s not in the same size game as the Toyota RAV4 or Mitsubishi Outlander, but is close in size to the likes of the Honda ZR-V and Mazda CX-5.

While there’s a few key practical storage spaces, there aren’t as many as some newer rivals, which does suggest the Atto 3 design is starting to date or just wasn’t well thought-out enough in the first place; such as putting all the switchgear in the centre console rather than on the dashboard.

This was probably done, at least in part, to accommodate the rotating touchscreen, which seems like a poor design and practicality choice to me. Especially the new one, which at 15.8-inches when rotated to the portrait mode it starts to interfere with your vision and the layout is more user-friendly in landscape mode - both when using the native multimedia system or your smartphone connection.

Space is respectable in the back seats, and there’s both a USB-A and USB-C port for charging devices. While out the back the boot measures 440 litres, which is a respectable amount of space for an SUV this size, but there’s only a tyre repair kit instead of a spare wheel.

That external size translates to a roomy cabin, which also has some flair to the design but thankfully a bit more restrained than the smaller Atto 3 - which is a bit over-the-top in this reviewer’s opinion. 

The element that sticks out immediately is the large central touchscreen which, like other models in the range, can rotate either vertical or horizontal, depending on your preference.

I don’t understand the point of this, because when rotated vertically it impacts your forward vision and can interfere with the air conditioning vents; and I can’t even see it with my polarised sunglasses.

It simply makes more sense horizontally, but I guess all carmakers are looking for catchy gimmicks these days. But while it may seem like a cool party trick it remains somewhat confusing to me, like one more thing to go wrong. But maybe I’m just getting old and grumpy.

What I do like and think is a great idea is double smartphone charging pads in the centre console. And overall the design of the cabin feels well thought out and has plenty of useful storage areas.

The seats are fine, a little flat and the fixed headrests are irritating, but overall they’re soft and supportive enough.

The key in the second row seating is the amount of space, with the extra length of the Sealion 6 compared to its rivals showing up with more knee room in the back for families with growing teenagers or those who need to carry their adult friends.

There’s also a pair of USB ports in the back too, so everyone can keep their electronics charged.

The boot is a good size, measuring 425 litres on paper, and has a nice long and wide floor. But some of that space is thanks to the lack of a spare - so that counts against it in my book.

Price is key to BYD’s success in Australia. Quite simply, the Chinese brand has undercut its rivals and consumers have responded to that, unsurprisingly in these tough economic times. The Sealion 6 follows the same path blazed by the Atto 3, Dolphin and Seal, offering plenty of vehicle for your money.

BYD Australia has kept it really simple, offering just two models - Dynamic and Premium - with very similar specification and separated primarily by powertrains.

The Dynamic is a less powerful, two-wheel drive option, while the Premium gets more grunt and all-wheel drive; but we’ll detail that later.

Both the Dynamic and Premium come with 19-inch alloy wheels, power-operated tailgate, a panoramic sunroof, powered front seats that are heated and cooled, a 15.6-inch touchscreen, Infinity premium audio, two wireless phone chargers and wireless Apple CarPlay and Android Auto.

The only non-powertrain difference between Dynamic and Premium is a head-up display on the latter model.

One noticeable absence from the Sealion though is a spare tyre. There’s not even a space-saver, just a tyre repair kit, which is disappointing and out of touch with the unique demands of the Australian market.

The Dynamic is priced from $48,990 (all prices exclude on-road costs), while the Premium starts at $51,990.

To put that into context with its competition, the Toyota RAV4 Hybrid range begins at $42,250 for the GX and stretches to $51,410 for the range-topping $51,410.

While, if you’re looking at an electric alternative, the Tesla Model Y currently starts at $55,900. The most direct rival, however, is the Mitsubishi Outlander PHEV which is only available with all-wheel drive and stretches from $57,290 to $73,790 across five variants.

As with the design there isn’t much to say about what’s powering the Atto 3 because it’s the same as the 2023 model. Both the Standard and Extended Range use the same front-mounted electric motor, which makes 150kW/310Nm and drives the front wheels through a single speed transmission.  

With 0-100km/h times of 7.9 seconds and 7.3 seconds respectively for the Standard and Extended Range, the Atto 3 won’t shove you back in your seat, but it has adequate performance for a mid-size SUV. 

While BYD has made its name in Australia as an all-electric brand it has always referred to itself as a 'new energy' company, and the Sealion 6 (and upcoming Shark ute) are why.

That’s because these feature BYD’s new 'Dual-Mode Intelligence' (DMi) powetrain - a hybrid system to you and me.

As mentioned above, the biggest difference between the Dynamic and Premium models is the powertrain, with two reasonably different systems.

The Dynamic is powered by a 78kW/135Nm 1.5-litre four-cylinder petrol engine, paired with a 145kW/300Nm electric motor - making for a combined system output of 160kW/300Nm. Notably, this powertrain only drives the front wheels.

In contrast, the Premium has an all-wheel drive set-up, combining a turbocharged version of the petrol engine (good for 96kW/220Nm) with a pair of electric motors, one on the front axle and one on the rear to produce a combined output of 238kW and 550Nm.

Both models get the same 18.3kWh ‘Blade’ battery, which is BYD’s proprietary technology underpinning all of its models and is attracting attention from other brands.

For reference, the Outlander PHEV has a 20kWh battery, Nissan’s X-Trail e-Power has a 2.1kWh battery, while the more conventional RAV4 Hybrid has just a 6.5Ah battery.

The Standard Range has a rated driving range of 345km (WLTP) from a 49.92kWh ‘Blade’ lithium-iron phosphate (LFP) battery while the Extended Range’s bigger 60.48kWh unit increases that to 420km.

Charging is capped at 70kW (DC) for the Standard and 80kW (DC) for the Extended. 

One of the major hurdles for EV brands is convincing people that they won’t run out of charge every day. At 420km the Extended Range Atto 3 will get most people through multiple days of commuting, so even with public charging you shouldn’t worry about range anxiety. 

Those drivers with commutes longer than 420km per day should be looking at something other than an electric car (and probably a job closer to home).

There are multiple modes to drive it in, including electric only, with the Dynamic able to go up to 92km on a single charge, while the Premium manages a claimed 81km.

However, it's important to note these are the NEDC standards and not the more real-world like WLTP,  so you may not achieve those in practice.

The claimed fuel consumption is an impressive 1.1L/100km for the Dynamic and 1.4L/100km for the Premium although again achieving those in the real world will take some effort.

With a 60-litre fuel tank BYD claims the Dynamic has a driving range of just over 1000km, while the Premium can manage around 960km.

It's also worth noting the Sealion 6 comes equipped with vehicle-to-load charging which means you can draw power from the batteries to run small electronic devices if you need to.

It’s a bonus feature that may or may not be of use, but is one of those things that may come in handy one day to get you through a camping trip or a BBQ at the park.

Driving the updated Atto 3 feels… fine. Nothing special or class-leading, but within the expectations buyers should look for in a mid-size SUV. Which is meant as a compliment to BYD, as it is still a relatively new brand in this very competitive market and there are certainly some noticeably worse rivals in this same segment. 

The Atto 3 may not be the most comfortable, most powerful or most dynamic mid-size SUV, but it’s a perfectly nice thing to drive and it will get you from Point A to Point B quietly and smoothly.

Another of the major changes for 2024 is BYD’s decision to ditch the fantastically named, but not very good Atlas Batman tyres, replacing them with Continental rubber. The Atlas tyres were a major drawback on the old model, lacking grip and detracting from the driving experience, with the new ‘Contis’ solving those problems. 

We drove the Sealion 6 Dynamic and despite having the less powerful powertrain it feels good on the road. The DMi system offers good performance, with quiet acceleration off the mark and a good integration between the petrol engine and electric motors. We haven’t driven the Premium yet, so we can’t make any comment on how different it feels.

It’s hard to make a definitive call on the Sealion PHEV powertrain because, like every plug-in hybrid, its greatest strength relies on how the owner operates it.

If you don’t charge the battery every day or so, you’ll just end up lugging around a battery and electric motor for little benefit. However, if you do keep the battery topped up, you can do most of your urban commuting without needing to turn the petrol engine on, which should result in some very low fuel consumption figures.

The company clearly knows this, which is why BYD Australia is offering a complimentary home charger to the first 3000 customers who order a Sealion 6.

Not only will that encourage sales but it will also help owners become evangelists for PHEVs in the future, because they’ll have the best possible experience.

So, a large part of its strength or weakness rests on the owner’s behaviour and that’s something we can’t assess.

As for the rest of the driving experience, the ride comfort is fine. It can’t match the class-leaders for compliance or dynamics, but the Sealion feels pleasant to drive around the urban environment and on the freeway at speed.

Biggest criticism is the steering is very, very light. While that makes parking easier, it feels so light you get very little feedback from the front wheels so it can feel vague at times.

Overall the driving experience is best described as fine. It doesn’t have any major vices but neither does it set any new benchmarks. 

Both Sealion 6 variants come equipped with autonomous emergency braking, front and rear cross-traffic alert/braking, 'Forward Collision Warning', 'Rear Collision Warning', lane departure warning/prevention, blind-spot detection, traffic-sign recognition, door-opening warning, trailer stability control, auto high beam, a 360-degree monitor, adaptive cruise control as well as front and rear parking sensors. Plus, it can even detect if you’ve left a child or pet inside the car.

ANCAP had not crash-tested the Sealion 6 at the time of publication, but with its comprehensive list of safety items it should tick most of the boxes when it comes to protecting its occupants and pedestrians.

BYD offers a six-year/150,000km warrant for the vehicle, with eight years/160,000km coverage for the batteries.

Service intervals are every 12 months of 20,000km and while a minor service is only $165, every second visit is more expensive, ranging from $498 to more than $600. There may be less oily bits under the bonnet but there’s still a cost to owning an electric car.

BYD is a small company but has partnered with mycar service centres to make maintaining your Sealion 6 easier. The Sealion is covered by BYD's six-year/150,000km warranty as well as its 10-year capped price servicing plan.

Service intervals are every 12 months/20,000km and prices range from $265 up to $1184 for the major eight year/160,000km tune up. Over the first five years, in keeping with most of its rivals, you’ll be paying $1648.

As I’ve written in previous BYD reviews, the biggest question mark hanging over the brand is arguably its long-term prospects. Quite simply, the brand is still too new to know how well it will perform on the used car market.

We also can’t tell you how it will hold up from a reliability point-of-view. We’re not suggesting there’s any doubt over its quality, but each car brand must prove itself reliable and dependable over time, and BYD hasn’t had that time yet.
