Alfa Romeo Junior vs BYD Atto 1

What's the difference?

The Alfa Romeo Junior is a cute car that’s charming and smile-inducing. It deserves to sell well but ultimately this will come down to whether the Australian public is receptive.

There is plenty of competition out there and if you're wanting something design-led, it's hard to look past this without spending much more money.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

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.

This is such a cute and tiny car with Alfa Romeo trying its hardest to sandwich all of its hallmark design traits in. It’s certainly a busy design on the outside which I don’t love right now, but I imagine I’ll grow to like it with time.

At the front there’s a special grille as standard that features Alfa Romeo script, plus an offset license plate and cool matrix LED headlights with the company’s ‘3+3’ lighting signature.

Around the side the 18-inch alloy wheels have a flower petal-like design, hidden second-row door handles, as well as a hidden serpent (Biscione) easter egg that’s laser etched into the C-pillar.

The rear of the Junior is my least favourite angle. It tries too hard to look more like a hatchback than a crossover SUV with the slanted rear window and the big black slab where the tail-lights are.

The twin exhaust pipes are a cute look, however, especially given the engine doesn’t scream performance credentials on paper.

Inside there’s an obvious attempt at making the cabin look and feel driver-oriented and sporty.

I like the seats which have a red section that runs down the backrest and onto the seat base. It helps break up the black finishes nicely.

Speaking of, however, there's a sea of black finishes throughout the rest of the cabin. I’d like to see some more silver or chrome accents as the glossy piano black may not age well.

There is interior ambient lighting around the cabin with a customisable colour, which looks great in low-light situations. It particularly pops in the large circular air vents which flank the dashboard and are shaped like cloverleaves.

If you look closely you may notice the Junior shares a lot of its physical switchgear with the related Jeep Avenger. Examples include the steering wheel buttons, gear selector, starter button and the physical climate control switches.

While there’s an argument to say that this cheapens the feel of the Junior, I’m thankful there is physical switchgear in this car to begin with. Plus, the Junior does look different enough as it is.

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 front seats in the Junior are very comfortable for longer drives. The driver’s seat in particular offers six ways of electric adjustability and a massage function. You don’t see features like that very often on a tiny SUV.

Ahead of the driver there’s a leather-wrapped steering wheel. It’s surprisingly slim which makes it nice to hold. There are also paddle shifters on the back which could be more pronounced.

As standard there’s a 10.25-inch digital instrument cluster which emulates analogue dials for the tachometer and speedometer. While the screen is high-res and clear, it’s interesting that Alfa Romeo chose to emulate dials in a digital way rather than just have physical ones, especially because you can’t change their appearance.

There’s a section in the middle that has a few different informative pages you can cycle through. I’d love to see more configurability given there’s limitless possibilities with a screen.

Moving across there’s another 10.25-inch screen for the central multimedia system. It certainly makes up for the lack of configurability in the digital instrument cluster and you can create and customise five different home page screens with a vast array of widgets. It’s fairly clever though at some point it feels like overkill.

There aren’t many menus or sub-menus to get lost in, however, the home button took me a while to locate. It’s above the touchscreen in a small pod of physical buttons alongside the hazard lights and door lock switch.

Underneath the touchscreen there’s a wireless phone charger, plus USB-C and USB-A charger ports.

The engine start button is mounted prominently on the centre tunnel with the lightswitch-like gear selector directly behind it. It’s mounted a little too close to the centre armrest which means craning my arm like a T-Rex to use it.

Other amenities up front include a deep console area with configurable cupholders, a sliding centre armrest with a cubby, as well as a tiny glovebox.

It’s very clear the second row of the Junior isn’t the focus. At 182cm tall I need to splay my legs on either side of the driver’s seat in my desired driving position. Despite this, toe room and headroom is adequate, even with the optional sunroof.

The second row isn’t a place anyone would want to spend too long in. Kids would likely suit better, plus there are top-tether points on all three rear seats and ISOFIX mounting points on the outboard rear seats.

Amenities are limited to a single USB-C port in the second row. There are no air vents or centre armrest. You need to make your own entertainment.

At the back there’s a hands-free power tailgate, which is rare for a vehicle of this size. Once it’s open, the available boot space is decent, especially for such a small car. There’s 415L of boot space with the rear seats upright.

The area itself is fine. There’s no load lip which allows you to get things in and out with ease, plus there’s a two-tier boot floor, allowing you to stow items under the floor away for prying eyes.

In terms of boot-related amenities there’s a 12V socket, a light and some hooks. It’s fairly standard back there.

Unfortunately there’s no spare wheel as standard in the Junior line-up. Instead there’s a tyre repair kit which is not super handy if you have a tyre blow out.

Thankfully you can purchase a space-saver spare wheel for the Junior Ibrida for $314 as a genuine accessory. It would be better if this came as standard given there’s the space for it.

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 Junior Ibrida is powered by a 1.2-litre turbocharged three-cylinder petrol engine with 48V mild-hybrid assistance.

In the six-speed dual-clutch transmission is a 21kW electric motor that’s fed by a 0.9kWh lithium-ion battery pack.

It’s worth noting that this is the exact same engine set-up that features in a growing number of Peugeot models locally, including hybrid versions of the 2008, 3008, 5008, 308 and 408.

Total system outputs are 107kW and 230Nm which is far from class-leading. Alfa Romeo claims the 0-100km/h sprint takes 8.9 seconds.

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 Junior Ibrida has a claimed fuel consumption of just 4.1L/100km, which is solid for a mild-hybrid vehicle.

There’s a 44L fuel tank which requires a minimum of 95 RON premium unleaded petrol.

During our 200km drive loop on the launch which consisted of mixed and spirited drive, we returned an average of 5.4L/100km. However, during one section with fewer twists and turns we saw an average of 4.0L/100km, which is incredible.

Using our as-tested fuel consumption there’s a theoretical range of 815km.

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.

Starting up the Junior Ibrida, the turbo three-cylinder engine roars to life with an off-beat, thrum-y sound.

If the engine is bone cold, it’ll stay on to get the fluids up to operating temperature. Once this happens it will happily switch off.

Initial acceleration is typically done on electric power alone and if you don’t press the accelerator too hard it’ll stay in EV mode at city speeds. It’s very electric-heavy for a car that’s technically only a 48V mild-hybrid.

At many points the engine switches off at speeds up to 80km/h, especially if you’re travelling on flat ground. Even at 100-110km/h, it’ll switch off if coasting.

Something to note is the electric motor is part of the six-speed dual-clutch transmission which means you can sometimes feel gear changes even when driving in EV mode. You do get used to this.

A positive of the electric motor being in the dual-clutch is it helps iron out awkward pauses and jerks that this type of transmission typically presents. It’s still not perfect though.

If you press the accelerator harder or the battery charge gets lower, it’ll inevitably fire up the three-cylinder engine. It makes a rorty note during acceleration which is fun to listen to.

The transition from electric to petrol is generally seamless. There can be a slight shudder when the three-cylinder first fires up at low revs, but I’ve experienced much worse in other cars.

There’s only one setting for regenerative braking, which is fairly strong and almost one-pedal-driving like. It takes a bit to get used to the feeling. You do still need to put your foot on the brake pedal to come to a complete stop.

With the combination of the petrol engine and electric motor, acceleration is far from break-neck but it’s far from slow. The fact it doesn’t have much power actually makes this car more endearing, especially because it’s rewarding to drive.

The steering in the Junior is communicative and direct. It's a joy to take corners in as the feel errs more on the lighter side. It almost has a Mini-like go-kart feel as the car feels so nimble.

Additionally, the ride is composed and settled, even at higher speeds on rough roads, which is rare for small vehicles. This is likely because the Junior only has 18-inch alloy wheels with a decent amount of tyre sidewall, rather than the low-profile 20-inch units that are offered in the Veloce Elettrica overseas.

On the highway the Junior’s cabin is surprisingly quiet. You can’t hear the three-cylinder once you’ve reached your set speed and there’s also minimal wind/tyre noise.

Lastly, the safety systems do a good job at working but not being annoying. The worst culprit is the intelligent speed limit assist which chimes when you go over the signposted speed limit.

If it does grate you too much, you can easily switch it off in a dedicated advanced driver assist system (ADAS) menu that can be reached via a shortcut button near the hazard lights. It’s as easy as that.

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.

Like other Alfa Romeos, the Junior is covered by a five-year, unlimited-kilometre warranty.

There’s also five years of roadside assistance as standard. An additional 12 months of coverage can be added for the lifetime of the vehicle every time you service at an authorised Alfa Romeo dealer.

Logbook servicing is required every 12 months or 15,000km, whichever comes first. The first five services are capped and total $3105.84, which averages out to around $620 each.

This seems pretty expensive for such a small car, but it's only a touch pricier than the Lexus LBX.

It’s clear maintaining this vehicle with its dual-clutch automatic transmission and mild-hybrid components is costly in the long run.

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.
