BYD Atto 1 vs BYD Sealion 8

What's the difference?

The BYD Atto 1 has already earned its place in history as the cheapest new EV ever sold in Australia. And the good news is that, on the strength of bigger-battery Premium version, it rarely puts a foot wrong as a city car, exceeding performance, efficiency, refinement and comfort expectations. The Atto 1 really delivers around town.

But the baby BYD’s price is too close to larger EVs with better range, while extended exposure reveals issues with seat comfort, touchscreen access/distraction, ADAS interference and nervous steering feel at speed. Australian road tuning is required to rectify these.

Still, as a cheap urban EV runabout, the Atto 1 Premium still (just) stands alone. A glimpse into the future, someday, all city cars will likely follow in the bold BYD’s footsteps.

There’s no denying the value the BYD Sealion 8 Premium offers as it packs a lot in for the price. Its efficiency and inoffensive looks add up to a good package and reflect what it does well. That said, the underwhelming driving experience and clunky media system are noticeable. Whether they're deal breakers is up to you.

Fun fact. Designer Wolfgang Egger was responsible for the gorgeous Alfa Romeo 156 of 1997 among others, as well as some Audis and Lamborghinis later on. You can definitely see the latter’s influence in the Atto 1’s angular face.

Based on the Dolphin architecture and badged the Dolphin Surf elsewhere (as well as Seagull but that name wouldn’t fly here), the BYD’s boxy proportions are pure supermini and is about the size of the previous-generation Honda Jazz.

However, the designers have added some crossover cues to the styling, including plastic cladding around the wheel arches, to give it a pseudo SUV look.

Inside, though, the Atto 1 is unashamedly hatchback in layout and appearance, with a contemporary, minimalist dash, big central touchscreen with precious few buttons and loads of storage.

In other words, a typical modern small car from China.

The Sealion 8 is a big unit, and its design leans more towards soft and rounded than sharp. There’s a sense of restraint with its pillowy panels, smooth curves and flush door handles all contributing to a clean, almost clinical look.

The 21-inch wheels add a bit of presence, as does the full-width LED light bar with its braided design. But overall, it doesn’t try too hard to stand out. It’s inoffensive - clean and easy on the eye, but it stops short of having any sense of identity.

Inside, the cabin carries that same restrained approach. There’s black leather upholstery, some interesting geometric detailing through the panels and speaker grilles and a generous use of soft-touch materials throughout.

The large displays and panoramic sunroof help lift the space, giving it a premium feel, but more importantly, it’s just a comfortable, easy place to spend time. Which, for a family SUV, arguably matters more than anything else.

The BYD’s boxiness sure pays dividends accessing the Atto 1's interior, aided by tall doors, a high roof and lofty seating.

Initial impressions are very positive.

Lots of space, a decent driving position (in the Premium at least; the Essential has rake-only steering adjustment), grippy little wheel and a solid look and feel impart a sense of quality. This does not seem built down to a price.

The elevated centre console/fixed armrest provides ample storage below and easy reach of USB ports, sturdy cupholders above and a raised smartphone rest that doubles as a charger (again, only on Premium), allowing for quick downward glances without having to touch the device. Helpful.

Further points are won due to the very clean and minimalist dash presentation, with an electronic instrument display ahead of the driver (not a given nowadays thanks to Tesla’s minimalism-gone-mad influence), offering all the information you need in a concise and notably colourful manner.

That 10.1-inch central touchscreen, meanwhile, is probably one of the better examples from China, possessing superficially logical operation, clear markings and a row of fast-access icons for climate, audio, vehicle function, home screen and other controls.

However, the more time you spend in the Atto 1, the more the cabin doesn’t stand up that well under scrutiny.

The shapely tombstone-style front seats, which look a million dollars, are comfortable on short journeys but disappoint during longer drives, revealing a lack of sufficient back and thigh support.

There are no regenerative braking paddle shifters for single-pedal driving, just an on/off tile requiring a distracting and time-consuming touchscreen-menu deep-dive.

In fact, most functions demand at least one or two eyes-off-the-road-ahead prods of the screen, which is annoying and potentially hazardous.

Using the climate control is a good (bad) example.

Infernally fiddly screen slide controllers that are hard to pin-point with a hovering finger while the car is moving, let alone modulate, leads to temperature-selection fury. And those vinyl seats are clammy regardless of humidity levels and their perforations don’t help. Setting the desired climate environment is an utter faff.

And why must BYD’s synthetic leather smell so pungent? The off-gas odour can be nauseating for some on warmer days.

Worse still, even a glance towards the touchscreen sets off the distraction nannies. Frustrating. So is the intrusive lane-keep assist tech, unless you keep the car perfectly centred, with its constant nudging of the wheel while it nags away. More like Aggro 1.

Inevitably, turning these and other ADAS warnings off requires several menu deep-dives, leading to more driver-distraction paranoia. It’s a circle of stupidity for tech that’s meant to protect. And every new drive defaults to ‘on’. It's an infuriating mess.

Meanwhile, the Atto 1’s (two-person-only, remember) rear seat area also starts off promisingly, with easy entry/egress, adequate space (even for long legs and big feet) and a backrest and cushion combo offering sufficient comfort and support.

Amenities include useful door storage, overhead grab handles and map pockets, while the back of the centre console provides a cubby area just wide enough hold a bottle or larger keep-cup. That’s necessary because there is no folding armrest or subsequent cupholders back there, nor reading lights or USB ports.

And while the upward sweep of the window line means the rear can seem dark, the shape of the front seats allows some vision around and even through them for rear occupants.

Further back, the boot area is larger than the BYD’s diminutive size suggests, at 308 litres with backrests erect and 1037L with them folded forward.

The deep floor hides an even deeper cavity that’s large enough for charger cables, laptops and other paraphernalia that should be out of sight. That almost negates the need for the AWOL luggage cover.

But there's also a tyre repair kit instead of a spare wheel in there, and regular readers will know how incorrect that is. Every vehicle sold in Australia should come with one. Even city cars.

Loading/unloading is easy and there are hooks to secure things to, but clearing the high lip may be an effort for some.

And, though an EV, the is no extra storage to be found under the bonnet. The Atto 1 has no front boot, or froot.

Up front, storage and general usability are well thought out. There’s a handy shelf tucked underneath the centre console with two USB-C ports, while a tray above houses the fast wireless charging pad. You also get a sunglasses holder, two cupholders and decent-sized bottle holders in the doors, so it’s easy to keep things organised.

Seat comfort is a highlight, and the overall layout is clean and easy to live with, but the same can’t be said for the multimedia system. While the graphics are sharp and the touchscreen is responsive, functionality isn’t always its strong suit. Wireless Apple CarPlay and Android Auto are included, but CarPlay required reconnecting on every drive during testing and the digital radio and phone calls experienced noticeable signal dropouts. It’s the kind of friction that chips away at the day-to-day experience and starts to feel out of step with how polished the rest of the cabin is.

There’s also a heavy reliance on the screen for core functions. Climate control is integrated, which is fairly standard, but so too are things like headlight controls. It might suit those who are used to navigating everything through a screen, but needing to dig through menus to adjust something like auto high beam on the move feels like a step too far. Bring back buttons.

The second row is where the Sealion 8 really leans into its family-friendly brief. Space is generous, with enough width to comfortably accommodate three adults and the flat floor helps here too. There are three top tether points and two ISOFIX mounts, while charging is covered by a USB-A and USB-C port.

Amenities are a standout. The outboard seats mirror the front with heating, ventilation and massage functions, which quickly become a favourite, alongside dedicated climate controls, roof-mounted air vents and multiple cupholders. A set of sunshades would round things out nicely, but it’s otherwise a very accommodating space.

Access to the third row is less impressive. The manual slide and tilt mechanism feels a little heavy and fiddly to operate and the space itself is best reserved for kids. In practice, that means younger passengers will likely take the path of least resistance, as mine did and simply climb over the second row instead.

Amenities are fairly basic, with directional air vents and cupholders, but there’s no charging provision back there. You do, however, get two top tether points and ISOFIX mounts, which will be a plus for larger families.

Around the back, the boot is a practical, usable space with a wide opening and flat loading floor. With all three rows in place, there’s 270L on offer, which is enough for a few school bags or a grocery run, expanding to 960L with the third row folded. There’s no spare tyre, just a repair kit, which may be a consideration for regional drivers. A 12-volt socket and powered tailgate round things out in this grade.

The BYD Sealion 8 range is relatively straightforward, with two grades on offer and the base variant available with a choice of two drivetrains. For this review, we’re in the flagship Premium AWD, which is priced from $70,990 before on-road costs.

It lines up against the Chery Tiggo 9 Super Hybrid at $65,430 driveaway, the Kia Sorento GT-Line PHEV from $71,130 before on-roads, and the Mazda CX-80 P50e Azami, which stretches up to $87,950 before on-road costs.

On paper, the Sealion 8 Premium doesn’t quite undercut the Chery on price or match its claimed 170km (NEDC) electric-only range, but it’s not far off, with a still-impressive 152km (NEDC). And when you look at the broader package, it starts to make a fairly strong value argument, particularly against its other key rivals.

The 'Premium' badge isn’t just for show, either. Equipment is generous, with highlights including a fixed panoramic sunroof with an electric sunshade, leather-appointed upholstery, a heated steering wheel, and heated, ventilated and massaging seats not just in the front, but for the outboard seats in the second row as well - a feature that hasn’t gone unnoticed by my nine-year old.

Technology is a clear focus. There’s a 10.25-inch digital instrument cluster, a large 15.6-inch touchscreen multimedia system and a 26-inch augmented reality head-up display, alongside wireless Apple CarPlay and Android Auto, a 50W wireless charging pad and a 21-speaker DiSound audio system. BYD also includes 2GB of data per month for the first two years to support its 4G connectivity and over-the-air updates.

Practical touches round things out, with keyless entry and start, NFC card access and a digital key via the BYD app, a powered tailgate, vehicle-to-load (V2L) capability, rain-sensing wipers, sound insulation for the front doors and windscreen and three-zone climate control.

The Atto 1's electric motor is offered in two output choices. Either way, it can be found under the bonnet and driving the front wheels via a single-speed transmission.

The Essential scores a low-power version making 65kW and 175Nm of torque, which is enough for a 0-100km/h sprint time of a still-decent 11.1 seconds, while the Premium’s high-power unit ups those to 115kW and 220Nm respectively, shaving two seconds off in the process. Top speed is said to be 135km/h.

Note that, while the latter grade’s 43.2kWh battery adds 96kg overall compared to the smaller 30kWh model, it still enjoys a way-superior power-to-weight ratio of 82.7kW/tonne versus just 50.2kW/tonne.

The BYD Sealion 8 Premium is all-wheel drive and pairs a 1.5-litre, four-cylinder, turbo-petrol engine with two electric motors, one on each axle. Combined outputs sit at a hefty 359kW and 675Nm, which comfortably out-muscles its key rivals.

Those figures do drop back to a more modest 110kW and 220Nm when running on the petrol engine alone.

Performance is strong for a large family SUV, with a claimed 0-100km/h sprint time of 4.9 seconds. You can toggle between pure EV and hybrid modes depending on the drive, which adds a layer of flexibility that suits short daily trips and longer highway runs.

The official consumption average for the Essential is 15.5kWh/100km and its 30kWh 'Blade' LFP (Lithium Iron Phosphate) battery offers a WLTP range of 220km.

The 43.2kW Premium bumps the energy use figure up to 16kWh/100km but offers 310km WLTP.

We came close to latter claim, with 263km of mixed driving and still showing about 10 per cent of range left, while the car’s consumption readout averaged 13.7kWh/100km overall. That rose to 16.5kWh/100km during a stint of harder, highway-heavy driving.

Charging times vary. With an 11kW AC capability on both grades, the Essential needs up to 16 hours and the Premium 22 hours plugged into a regular socket, and five and seven hours respectively using an optional 7.0kW Wallbox.

Meanwhile, switching to DC fast charging, the Essential’s 65kW capability means a 10-80 per cent top-up can be achieved in under 40 minutes, against the 85kW Premium’s 30 to 50-minute requirement.

Charging is handled via a Type 2 CCS port, with support for up to 11kW on AC and up to 74kW on a DC fast charger. BYD claims a 30 to 80 per cent recharge can be done in as little as 20 minutes under ideal conditions.

The 35.6kWh lithium iron phosphate (LFP) battery is a standout, delivering a claimed electric-only driving range of 152km on the NEDC cycle. That figure is on the optimistic side compared to WLTP testing, but even with that in mind, it remains an impressive number for a plug-in hybrid of this size.

With a full battery, the combined fuel consumption is rated at just 1.0L/100km, translating to a theoretical driving range of over 1000km. Real-world results will vary depending on how often you’re able to charge and the type of driving you’re doing, but after a week that included a fair stretch of highway driving, my trip computer was showing 6.3L/100km. Overall, it’s a solid result, particularly for something with this level of performance.

Sadly, we cannot comment on how the 65kW/175Nm Essential drives, but with 77 per cent more power and 25 per cent more torque, the 115kW/220Nm Premium’s performance is one of its calling cards.

Lively off the mark, even in Eco, it thrives in inner urban environments, with instant throttle response for effortlessly zippy and smooth acceleration, as you’d expect of an EV.

And it just keeps on keeping on at speed, giving the Premium a terrific breadth of performance flexibility. We’re now very curious to see how the Essential goes.

Armed with light and alert steering, the Atto 1 can weave in and out of traffic gaps with confidence and precision, and is backed up by a super-tight turning circle to boot, so parking manoeuvres around town is a doddle.

BYD’s decision to set up the chassis for a soft, long-travel suspension is appreciated, since the Premium takes most bumps and humps in its stride, making this one of the comfier city cars around.

Road and tyre noises are omnipresent, but aren’t not too bad overall by supermini standards, while the Hankook 185/55R16 tyres deliver sufficient grip, even over some rain-soaked roads we endured.

Most of these Atto 1 attributes also translate well at freeway speeds, with the Premium offering ample muscle for overtaking, slick steering responses and a planted chassis feel.

But, once you hit some faster corners, the BYD’s reactive steering, lofty seating and cushy suspension conspire to create considerable body movement, especially through tighter bends, scrubbing the front wheels as it turns wide (understeer).

Yet, press on a bit harder, the Atto 1 can instantly change its attitude to oversteer, feeling darty as weight shifts from the rear, making the steering suddenly too sharp and the car too nervous, Even experienced drivers might hesitate to carry on. And this happened on dry roads.

Of course, the BYD is a city car so not designed for sports-car handling, but it does lack the confidence and control of a hard-driven Mazda 2 or Suzuki Swift. Strangely, it seems more SUV-like than supermini, dynamically.

Most owners won't care, but they will have to live with the infuriating ADAS tune, with inexplicably sudden braking when the adaptive cruise control is on, and lane-support systems that all-too-often tug and bleat endlessly like an agitated goat, becoming too distracting, and requiring far-too-fiddly touchscreen menu diving to silence, especially as they default back on with every restart.

The driver-attention warning is also in a semi-permanent state of nerves, squawking all-too-regularly unless the driver is sat perfectly still, and will easily escalate the danger level to “take-a-break” should you dare move about in your seat. Which would be regularly, due to the latter’s lack of enduring support. A literal and metaphorical pain.

Clearly, then, the Atto 1 can really do with some Australian road tuning and on a number of fronts at that. Until this happens, these are the dark clouds blighting the blue skies that this car’s otherwise sunny disposition delivers with every urban drive on a daily basis.

Or, in other words, stick to the urban jungle.

On-road performance is where things become a bit of a mixed bag. There’s no denying the Sealion 8 Premium is quick and it leans more heavily into its EV character than many large plug-in hybrids. It’s quiet in hybrid mode and responsive off the mark, which makes it easy to keep pace in traffic and overtake when needed. For something of its size, it also does a good job of masking its weight on the move.

Regenerative braking is offered in two levels, but even the stronger setting feels fairly mild. The upside is smoother low-speed driving, with none of the abruptness you sometimes get in hybrids, and it does still recover a decent amount of energy, particularly on longer descents.

Where it falls short is in its overall dynamics. The steering and suspension are tuned for comfort, which results in a soft, slightly floaty feel on the road. It’s not unpleasant and around town it actually suits the car’s brief, but there’s a noticeable lack of feedback and control if you’re expecting something more composed.

Visibility and driver positioning also take some getting used to. The forward view is decent, but the pillars are quite thick and it can be difficult to find a driving position that doesn’t feel a little enclosed.

Judging the edges of the car isn’t always intuitive, and while the 360-degree camera is clear, its perspective can feel slightly off. Objects tend to appear much farther away than they are, which isn’t the most reassuring combination when you’re trying to manoeuvre in tighter spaces.

The BYD Sealion 8 is yet to be tested by ANCAP and therefore remains unrated at this stage. That said, it comes equipped with a comprehensive suite of safety features, along with nine airbags including side chest airbags for the front and second rows.

Standard equipment includes seatbelt reminders for all seating positions, front and rear parking sensors, driver attention monitoring and alert, tyre pressure monitoring, traffic sign recognition and autonomous emergency braking. It also features front and rear collision warning, blind-spot monitoring, rear and front cross-traffic alert and side exit assist.

On the road, however, some of the active safety systems are less polished in execution. The adaptive cruise control can feel abrupt when slowing down and slow to regain speed, while the steering assist can be overly reactive through corners. Lane keeping also lacks consistency, with the system not always engaging as expected.

For families, child seat provision is strong, with four ISOFIX anchor points and five top tether mounts across the cabin, along with child presence detection.

Here’s where the BYD slips up a bit.

Yes, it comes with a better-than-industry-standard six-year warranty, but many rivals offer between seven and 10-year coverages, while the Atto 1’s mileage warranty is capped at 150,000km when most others include unlimited mileage. And roadside assistance is only for one year, as well.

Service intervals are every 12 months or 20,000km. Capped-price servicing is available, but no precise figures were available at the time of publishing.

Estimates are from under $200 for the first and third annual services, and from $500 and $650 for the second and fourth yearly visits, respectively. Please check with BYD for updated figures.

Currently there are about 105 BYD service outlets throughout Australia, with 30 more expected by the middle of 2026. This should address one of this brand's biggest concerns – sufficient after-sales care.

BYD offers the Sealion 8 with a six-year/150,000km warranty and an eight-year or up to 160,000km battery warranty. Both terms are competitive for its class.

Service is recommended every 12 months/20,000km with each workshop visit averaging a solid $596 for the first five years (year four is $1360). Accessing a BYD service centre is fairly easy as there are around 70 centres nationwide now.

BYD recommends premium unleaded petrol (95RON) to be used for the Sealion 8.
