Hyundai Ioniq vs BYD Atto 1

What's the difference?

Just like the Kona EV, Hyundai's Ioniq is still one of the best EV options on the market today. It strikes an excellent balance by offering significantly more range and better energy consumption than the more affordable Nissan Leaf or MG ZS EV, while providing the familiarity of the Hyundai spec and drive experience at a price only a little higher than a top-spec Prius.

Its relatively high score is a product of these factors, but also the way in which its interactivity offers the early adopters the engagement they will be searching for.

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.

The Ioniq follows in the footsteps of eco hatches before it. You'll note this car's similarity in profile to the Toyota Prius, both shaped as such to secure low drag figures and therefore better economy and longer range.

While the Ioniq is a little more sedate than the wacky angles of the current Prius, there's no getting around the fact it's not exactly a cool shape. You could say it's interesting, perhaps, in the way it warps the low-drag box to Hyundai's styling cues, but dorky nonetheless. The LED headlights help lift it  a little, but the filled-in grille and small 16-inch wheels hardly lend this car extra street cred.

The Ioniq is more a proof of concept for early adopters who care a little less about the way the car looks and a little more about its drivetrain and technology, which is clearly the  focus here.

This can be seen in the Ioniq's interior, which has been re-worked for its most recent update. The digital features are impressive, with the floating 10.25-inch screen now totally dominating its dashboard.

I also like how the brand has given the instrument cluster a more modern design, with a cool floating bridge element over the top to eliminate glare, and, as always, Hyundai has made ergonomic use of its excellent switchgear and tidy steering wheel from the i30 and Kona ranges.

The climate unit has lost its tactile dials, replaced by touch-panel controls, and the lack of a transmission under the centre console has allowed plenty of negative space for the brand to play with, in this case a huge storage bay. There are also elements from more recently launched Hyundai models, which help to tidy the centre space up further, like an upright wireless-charging bay and shift-by-wire drive selector, which all looks very modern and neat.

It's a step towards things to come from the newly minted Ioniq sub-brand, which will do a lot more of this stripped-back, space-saving stuff with its next vehicle, the Ioniq 5 SUV. For now, though, the Ioniq is good as a half-step into the future. It's not as outlandish as a Tesla Model 3, for example, and will better suit a buyer looking for something a bit more familiar that still has a futuristic edge.

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.

As mentioned, there's actually quite a lot of space in the Ioniq cabin, and the design has been further stripped back with its most recent updates.

The front seat seems a bit high for a hatch, although ergonomically everything is correct for the driver, with a good amount of adjustability in the seat back and wheel.

The big, bright multimedia touchscreen is easy to use, and the single centrally mounted volume dial is welcome, but I do sorely miss the dials  for adjusting fan speed and temperature. Touch-panel controls, to me at least, are always inferior.

As already mentioned, the centre-console area under the climate unit has been almost entirely deleted for the electric variant, granting the driver a little more knee room, and leaving a deep rubberised bay for loose objects, maybe even small bags. This area also houses two 12v power outlets and one USB port. The centre console has been re-worked to include a smart, space-saving upright wireless-charging bay for your phone, the shift-by-wire console, and controls for the heated and ventilated seats. This area also hosts two large bottle holders, and a large centre-console box.

As is usual with Hyundai models, there's also a large bottle holder in the door, alongside a practical bin.

Rear passengers are treated to decent legroom, about on par with what you'd expect in a hatchback. Headroom is a little limited, both for getting in and out, with the descending roofline, so if you have family or friends taller than my 182cm height, they might be less than pleased.

The rear-seat area gets bottle holders in the doors and in the drop-down armrest, although there are no power outlets, just dual adjustable air vents.

The hatch body of the Ioniq makes for a decent boot volume of 357 litres, enough for a large pram or, in the case of my testing, the largest of the CarsGuide luggage cases, with ease. Hyundai gives you a little satchel to tidily store the standard powerpoint to Type 2 charging cable. A Type 2 to Type 2 cable, which you will need to charge at public outlets (up to 7.2kW) is not included.

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.

And… what a perfect time to release Australia's cheapest new EV!

Sat alongside the base Essential from $23,990 (all prices are before on-road costs unless otherwise stated) is the Premium as tested here, starting from $27,990 and representing a $4000 difference.

But oh, what a difference.

The cheaper Essential comes with a 30kWh battery, providing a WLTP range of just 220km. Usefully, the Premium’s battery is 44 per cent larger at 43.2kWh, boosting range to a more-comfortable 310km, while power jumps by 77 per cent.

Every Atto 1 includes synthetic leather-trimmed seats, a 10.1-inch central touchscreen, rear camera with sensors, adaptive cruise control as part of some Advanced Driver Assist Systems (ADAS) tech (more on safety later on), wireless Apple CarPlay and Android Auto and even Vehicle to Load (V2L) functionality, so you can use your hairdryer on the fly. Handy!

However, the Premium ups the ante with a surround-view monitor, powered and heated front seats, reach as well as rake adjustment for the steering wheel, a wireless charger, LEDs rather than halogen headlights and 16-inch alloy wheels instead of 15-inch steelies with hubcaps.

But… both are four-seaters only. And neither offers an exterior temperature gauge, remote keyless entry from the passenger side (you’ll always need to press a fob), a luggage cover or a spare wheel – just the totally-unsatisfactory tyre repair kit.

Plus, there’s no heat pump so, in winter, turning the temperature up will drag range down noticeably, while a lack of liquid cooling for the battery will do the same during a hot Aussie summer, since the AC has to work overtime doing that job instead.

And we’re not convinced the Atto 1 represents such great value.

Yes, that small-battery Essential undercuts every hybrid bar Suzuki’s (mild-hybrid) Swift, including the MG3 Hybrid+ and Toyota Yaris HEV, and even the ageing Mazda 2 petrol costs more, but its limited range means it’s better as an inner-urban, small-distance-only commuter proposition. Best as a second or even third car.

Meanwhile, the bigger-battery Premium is priced perilously close to significantly larger EVs with greater range, including BYD’s own Dolphin from $29,990, the MG4 Urban from $31,990 drive-away, GAC Aion UT from $32,990 drive-away and the coming Geely EX2.

And, alongside cheaper-still petrol-powered alternatives such as the Kia Picanto, MG3 and MG5 sedan, there are also smaller SUVs that slip beneath the bijou BYD, like the Chery Tiggo 4, Haval Jolion, Hyundai Venue, Mahindra XUV 3X0 and MG ZS.

What we’re saying is, unless the Atto 1’s sub-four-metre length and narrowness are paramount, it’s behind the eight-ball for value against an array of more-substantial alternatives costing not much more.

Still, we get this is that rare thing today, a truly-new city car and we’re here for that.

The Ioniq electric has a single motor on the front axle producing 100kW/295Nm. It's the least powerful EV in Hyundai's range, but still out-punches cars like the Toyota Prius on raw power. It drives the front wheels via a single reduction-gear transmission, and the Ioniq electric also has re-worked regenerative braking for its most recent update.

This is powered by a huge-for-its-size 38.3kWh lithium-ion battery pack under the floor.

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 huge 38.3kWh battery pack and official combined energy consumption of 15.7kWh/100km, grants the Ioniq electric an impressive 311km (WLTP) range. As already mentioned in the pricing section, this lets the Hyundai electric hatch strike a good balance for urban commuters, however, under our mostly urban testing, it's an even better story.

For context, electric cars are far more efficient when operating in an urban scenario than they are on the open road. This is because they can regenerate energy more often and are less susceptible to losses from drag. The Ioniq has a superb regenerative-braking system, which can be completely customised to the user's preference. Want to drive it with no regen braking (like a normal car)? You can. Want to have the full eco experience, and have the car's motor bring it to a halt even without using the brake pedal, thereby maximising the amount of energy recouped? You can absolutely do that, too.

For most of my week, I stuck the Ioniq in its maximum regenerative setting and was very impressed to find it return an efficiency rating of 12.3kWh/100km. Not only is this number well below its claim, it's by far the most efficient electric car I have driven, and the only one I haven't tried yet is the brand-new MG ZS EV.

Colour me very impressed. The Ioniq charges via the most popular socket, the European Mennekes Type 2 combo. On DC, the Ioniq can charge as fast as 100kW allowing for a charge time of 54 minutes from empty to 80 per cent. On AC, its max charge input is a frustratingly low 7.2kW, making for a charge time of six hours and five minutes (more expensive rivals will charge at 11kW or even the max 22kW),  while from a 240v wall outlet (~2.3kW) it will charge in 17 hours and 30 minutes.

My single charge session was at a council-supported clean-energy Tritium charger with a max output on DC of 112kW. It charged my Ioniq from about 35 to 80 per cent in 32 minutes, and cost around $7.

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.

The Ioniq's familiar Hyundai switchgear makes it largely feel like the brand's i30 from behind the wheel, and this is a very good thing. This car is immediately ergonomic and user friendly, although the seating position is a little high, preventing it from feeling particularly sporty.

The Ioniq emits a pleasant choral tone at low speeds, which enhances the perception you're steering something from the near future. It also helps alert pedestrians nearby, which was one of my pet peeves about the silent Tesla Model 3. The noise is interesting enough that you'll have people peering closely at it to figure out what's going on. It even gets louder as you accelerate, as though the motor is making it and it's not entirely artificial. Cool.

This EV is silky smooth to drive and accelerate. Like other Hyundai electric cars, it doesn't have the unleashed electric torque of a Tesla, but it feels  well attuned to driving around in an urban scenario, with viscous acceleration and regenerative braking. I was surprised to discover how heavy it feels, though.

I was expecting it to be heavier than its hybrid or PHEV counterparts but compared to the hybrid Prius I drove only a week or two prior, the electric Ioniq feels obese.

Upon closer examination, the Ioniq electric weighs 200kg more than the Prius, at 1575kg. It doesn't sound outrageous but it's enough to have this little car's suspension wallowing and occasionally crashing over bumps that wouldn't bother its hybrid versions or, indeed, the Prius.

This is perhaps emblematic of the issues facing smaller EVs like this. To get more than 300 kilometres of range, they need a lot of heavy batteries. Manufacturers can better hide this with the existing heft and better suspension travel of SUVs. The Kona EV, for example, feels less hefty than this little hatch.

Regardless, the electric motor dispatches with the Ioniq's weight easily when you really want to accelerate, and while it doesn't provide the hold-on-for-dear-life acceleration of Teslas, it's more than enough for a daily commuter. Unlike the Prius, the Ioniq does genuinely feel pretty sporty in the corners, thanks to steering that's on the heavier side, and a firm, responsive damper tune.

The regenerative braking is particularly good on the Ioniq. Using paddle-shifters usually reserved for changing gears, the Ioniq instead lets you  alter the amount of regenerative braking available. Feel like coasting a bit faster? Flick the Regen braking off. Feel like maximising economy and range? Max it out in the drive mode of your choosing, and you can use it as essentially a ‘single pedal' car (you can go or stop by using the throttle alone).

It even has an auto mode, which I found to be pretty intuitive. Paired with a few different display options to let you get superior feedback on how you're tracking with battery usage, it's brilliant, and more electric vehicles should take note.

So, this is an eco-focused electric car that is reasonably engaging to drive if a little heavy. Most importantly for the electric era, it's highly interactive, helping you really understand how your inputs are affecting its battery usage, and how you can better drive it to maximise range.

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.

The Atto 1 debuted in China back in 2023, but this is a facelifted, international-market version evolved mainly for European consumers, so crash-tested by Euro NCAP only last year, and scoring a maximum five-star ANCAP rating.

Note, though, that while the baby BYD includes Autonomous Emergency Braking (AEB) with forward collision warning, lane-departure assist and adaptive cruise control as standard, there is no blind-spot monitor or rear cross-traffic alert. Odd for a city slicker.

Six airbags are fitted, including curtain protection for all outboard occupants, while there are two rear-seat sited ISOFIX anchorage points and child-seat tether points behind each backrest.

Hyundais are all covered by a competitive five-year and unlimited-kilometre warranty, which includes 12 months of roadside assist. The roadside assist is topped up for an additional 12 months with every genuine service, and the battery pack in EV models like the Ioniq is covered for eight years or 160,000km.

Hyundai's service pricing is amongst the best in the business, and with less moving parts, the electric Ioniq is the cheapest in the range with the first five services for the life of the warranty fixed at just $160 per 12 monthly or 15,000km interval.

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.
