BMW 528i vs BYD Atto 1

What's the difference?

Sleek and attractive in the city,  engaging on a country back road and with plenty of clever technology, the 5 Series sedan ticks all the right boxes as an executive express. If you can stomach the price hike, the six-cylinder 540i is our pick of the bunch.

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.

Hardly a revolution, the 5 Series has instead undergone a few nips and tucks. But if it ain't broke and all that. It might not be the most head-turning offering, but the 5 Series sedan remains sleek, powerful and understated, and it is undeniably handsome on the road.

Its 8mm wider, 28mm longer and 2mm taller than the car it replaces, but it's also around 95kg lighter, thanks to its aluminium doors and boot and a clever magnesium frame for the instrument panel that saved another two kilograms. There's some other clever design elements, too. The kidney grille has active air flaps that open when extra cooling is required, closing when it isn't, reducing drag and helping accleration.

Inside, the 5 Series offers a beautifully crafted yet joyously understated cabin, with quality materials joining modern technology in a seamless way.

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.

This is a full-size sedan, and every seat feels spacious and airy. The sloping, slightly coupe-style roofline does cut into headroom in the back, but human-sized people will have little trouble, even sitting behind a tall driver.

Each trim offers two cupholders in the front, with another two housed in a pull-down divider that seperates the rear seat. And there's two ISOFIX attachment points, one in each window seat in the back. 

The 5 Series' boot opens to rival a surprisingly sizeable storage space, offering 530 litres with the 40:20:40 rear seats in place.

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 hunt for efficiency sees all but the most expensive 5 Series models equipped with four-cylinder engines, including the entry-level 520d, which is fitted with a 2.0-litre diesel unit that will produce 140kW at 4,000rpm and 400Nm from 1,750rpm. That's enough to push the cheapest 5 Series to 100km/h in a not particularly inspiring 7.5 seconds, topping out at 235km/h.

The cheapest petrol, the 530i, arrives with a turbocharged 2.0-litre engine good for 185kW at 5,200rpm and 350Nm from 1,450rpm. That will see you clip 100km/h in 6.2 seconds and push on to a limited top speed of 250km/h.

The turbocharged six-cylinder feels right at home in a car this size, with acceleration effortless and freeway overtaking manoeuvres an absolute breeze.

The 530d introduces the first six-cylinder engine, a 3.0-litre unit that will produce 195kW at 4,000rpm and an impressive 620Nm from 2,000rpm. That's enough to knock off the sprint in in 5.7 seconds and offers a top speed limited to 250km/h.

Finally, the top-spec petrol, the 540i, will produce 250kW at 5,500rpm and 450Nm from 1,380rpm from its 3.0-litre turbocharged straight-six engine. Those are healthy numbers, and enough to welcome 100km/h in a sprightly 5.1 seconds before topping out a limited 250km/h.

Every model is paired with an eight-speed torque converter automatic transmission.

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.

BMW quotes a combined 4.3 litres per hundred kilometres from the 520d, which will also spit out 114g per kilometre of C02. The 530d lifts that number to 4.7 litres per hundred kilometres (which seems a small price to pay for all that extra torque), with C02 pegged at 124g per kilometre. Both diesels get a slightly smaller tank, at 66 litres.

The 530i will sip a claimed/combined 5.8 litres per hundred kilometres, with C02 emissions a claimed 132g per kilometre, while the big 540i requires 6.7 litres per hundred kilometres, with C02 pegged at 154g per kilometre. Both petrol models get a 68-litre tank and require 95RON fuel.

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.

BMW's pre-drive briefing was so technology focused we half expected the black turtle neck and dad jean-wearing ghost of Steve Jobs to emerge from behind a curtain clutching an iPad. Only a minuscule portion was dedicated to the cars' drivetrains, with BMW instead hammering home autonomy functions, technology upgrades and the fact that its car was a preview to "the future".

But once we'd slipped behind the wheel of the all-new 5 Series, it all started to make more sense. Having briefly sampled three models (the 530i, 530d and 540i), we can safely report there's nothing particularly revolutionary about their on-road behaviour. That's not necessarily a bad thing - they do everything you could ask of a car in this bracket. They're mostly smooth and always quiet, the new chassis has done nothing to dampen engagement when you start to ask a little more of it, and it's generally a luxurious experience. But then so was the old car.

But what's new is the technology poured into the 5 Series. Every car gets what BMW is calling its personal co-pilot, for example, which is a set of tricky systems (there's six cameras, five radar sensors and 12 ultrasonic sensors scattered around the car) that work with the active cruise control and allow the car to be driven completely autonomous for 30-second intervals. Now, it's not quite as advanced as some of its competitor's systems - it can't change lanes for example - but if you're out on a country road or on a highway, it will stay within its lane, turn around corners and keep up with the traffic, even if they stop in front of you.

This is a full-size sedan, and every seat feels spacious and airy.

While the cheapest diesel model has historically been the best seller, BMW is hoping the new 530i will prove the most popular this time around. And while you couldn't describe it as fast, the power from its four-cylinder engine is ample for all that will likely be asked of it, and it feels sorted and composed on  more challenging roads. It's a smooth and comfortable ride, too, even with the optional 20-inch alloys fitted, though that's undoubtedly thanks to the adaptive dampers and ever-changing dynamic ride function, both of which are fitted as standard. In fact, we're yet to drive a car without those options fitted, so we're forced to reserve judgement on the as-standard ride quality of the cheaper models.

Be warned though, none in the 5 Series range offer the disconnected and perfectly smooth conveyance you might find in some true luxury offerings, and you'll still know when you're diving into deep pockmarks in the road. But the trade off is a an engaging ride and steering set up that always feels planted, with enough feedback to ensure you feel connected to what's happening beneath the tyres. And that's a trade we're more than willing to make.

Step up to the 540i and things take a much sportier turn. The turbocharged six-cylinder feels right at home in a car this size, with acceleration effortless and freeway overtaking manoeuvres an absolute breeze. And while we didn't find roads quite brutal enough to really test the active anti-roll bars housed at each axle, there's a wonderful and stable flatness to the way the biggest petrol handles corners.

It's not cheap, but thanks to the bigger engine and sorted dynamics, the 540i feels most like a 5 Series probably should.

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.

The BMW 5 Series is covered by a three year, unlimited-kilometre warranty, and requires condition-based servicing (rather than a pre-defined service interval).

You can also prepay your maintenance costs for five years/80,000kms, with prices ranging from $1,640 for the basic package, and climbing to $4,600 for the all-inclusive option.

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.
