BMW 118i vs BYD Atto 1

What's the difference?

The 118i has restored my faith in entry-level models from premium brands. Could it do with more standard gear? Absolutely, especially at $50K, and given what you could get in a higher-grade variant from a mainstream manufacturer, like the Mazda3 or VW Golf.

But the 118i is a cut above the mainstream hatchbacks in terms of performance, driver engagement and how the car makes you feel. 

If value is the priority, look elsewhere. But if your budget stretches this far and you can live without some of the luxo features, there’s little to complain about with the 118i hatch.

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.

Since the first-generation model arrived on the scene in the early 2000s, the 1 Series has had a slightly awkward design, partly due to the rear-wheel drive underpinnings. But this latest third-gen model, that debuted in 2019, is by far the most sleek and stylish yet. 

This is helped by the slimline tail-lights, rising shoulder line and well-executed front-end design with the signature BMW quad headlights and wide 'kidney' grille. 

In Australia the 118i comes as standard with 'M suspension' that lowers the ride height by 10mm, which gives it even more of a hunkered down look. The 'Black Sapphire' paintwork of the test car also upped the sexiness of the little hatch.

The 1 Series, and its competitors from Benz and Audi, are all visually appealing in different ways, ensuring they will each appeal to different buyers. 

The interior design is unmistakably BMW, which hasn’t evolved significantly for about 15 years. Although new-generation models like the iX and the soon-to-launch X1 SUV prove that BMW can evolve.

BMW’s overall dash design and layout isn’t a million miles away from the edgy angular look of the new Audi A3 - and that’s no criticism.

The mixed synthetic leather and cloth trim on the seats has a cool blue cloth motif to break up the grey and add a small splash of colour to the cabin. Matching blue stitching on the dash and doors is a nice touch.

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.

Up front the 118i’s sports seats offer unbelievable levels of lateral support, and despite the bolsters being adjustable, it might be a little too snug for some. It’s expected for a pricey hot hatch but not the lower grade 1 Series. And given how much side support there is, it could do with a touch more under-thigh padding. The driver’s seat is power adjustable while the front passenger has to adjust their seat manually.

The typically chunky BMW M leather steering wheel looks and feels expensive and offers good grip. The minimal steering wheel controls are well labelled with text or clear icons. I appreciated the analogue air conditioning controls instead of them being buried in a multimedia screen menu.

The multimedia system menu is unfussy and while it’s not as tech heavy as some other systems, I don’t see that as a negative. It just means there are fewer functions you’re forced to remember. You can control the system via the 'iDrive' controller in the centre console or it can be used as a touchscreen. I like the way users are given both options. The 10.25-inch screen is nice and wide but quite narrow. Overall, BMW’s operating system is easy to use and functions well.

In terms of devices, the 118i has a wireless charging pad, as well as a USB-A and USB-C port, and a 12-volt charger up front.

It has a smallish central bin, but it’s fine for a number of smaller items. Tall bottles fit easily in the door storage bin and there’s a secondary slot for other items. The 118i comes with a decent sized glovebox, and two front cupholders with a nook for phones just behind it.

The 118i is more spacious than anticipated, especially in the second row. The back of the front seats are scalloped, allowing for a little extra knee room, but there is a good amount of legroom generally, and plenty of headroom, despite the lower roofline. 

The rear seats are on the flat side but still comfortable, and there are ISOFIX points on the two outboard seats.

Rear seat occupants have access to map pockets, two more USB-C ports, and storage for big bottles in the doors (just), but there are no rear air vents. The seats fold 60/40 and there’s no central armrest.

Open the hatch and you’ll find a reasonably sized boot that can swallow 380 litres, expanding to 1200L with the rear seats stowed. There is plenty of under-floor storage because there’s no spare tyre on account of the run-flats favoured by BMW. There are, however, a couple of tie-down anchors and shopping bag hooks.

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 118i is powered by a three-cylinder turbocharged petrol engine, offering up 103kW of power and 220Nm of torque. It’s the same unit found in the Mini Cooper, albeit uprated by 3kW for the BMW.

It is front-wheel drive and the engine is paired with a seven-speed dual-clutch automatic transmission.

BMW says the 118i can cover the 0-100km/h sprint in 8.5 seconds.

If you’re after a quicker 1 Series, then the 180kW i28ti or 225kW Mi35i xDrive could be a better pick.

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.

According to BMW, the 118i consumes 5.9 litres of fuel per 100 kilometres. During my week of mixed driving with the hatch, I recorded a much higher average figure of 10.8L/100km. This was exacerbated by the fact I did my main test drive shortly before returning the car. It was much more efficient around town.

It has a 50-litre fuel tank and does require premium 95 RON petrol. In terms of CO2, the 118i emits 135g/km.

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.

To be honest I wasn’t particularly hopeful of an engaging driving experience with the 118i given I have been underwhelmed by the base Mercedes-Benz A-Class. But after a week with the 1 Series, I reckon it might well be the pick of the premium players in this segment.

The 118i is also a much more enjoyable car to drive than the entry-level version of the outgoing X1 SUV with which it shares a powertrain. If you don’t need the extra cargo space or the ride height of the X1, then please test drive the 118i just to see what you’d be missing if you opted for the X1.

BMW has always excelled when it comes to building punchy powertrains for driver’s cars, and that continues to be true, even for its smallest internal combustion unit.

The 103kW/220Nm turbocharged three-pot is smooth yet responsive, offering linear power and torque delivery and acceleration that will bring a smile to your face.

Obviously it’s not as quick as its sportier 1 Series siblings, but make no mistake, you can still have fun in a 118i.

There’s a little bit of lag when taking off and some hesitation from the seven-speed dual-clutch transmission during shifts, but neither are deal-breakers.

That obsession with driver engagement has paid off with the steering which is quick and direct.

The suspension is geared towards dynamism and as a result of that, and the sharp steering, you’ll be seeking out the nearest twisty section of road every time you get behind the wheel. It’s planted in corners with excellent road-holding characteristics.

Unfortunately that dynamic tune, and the low-profile tyres, means the ride is on the firmer side and a little jiggly around town, but it settles at speed. 

In terms of visibility, the 118i has huge B- and C-pillars, small rear side windows and a narrow rear windscreen, so you’ll be relying on the parking sensors and camera. The 11.4m turning circle feels large for a small car, too. 

The cabin is well insulated from some outside noise but coarse chip roads will make their presence felt.

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.

BMW continues to offer a three-year/unlimited kilometre warranty for its models, which is disappointingly a couple of years off most rivals these days.

The German giant also does things a little differently when it comes to servicing. Instead of service schedules, it has ‘condition-based servicing’, which is when the vehicle’s computer will inform you when the car needs a service. 

BMW’s Service Inclusive pre-paid plan runs for five years or 80,000km for the 1 Series, and costs $1700 up front when you buy the car. That averages out to about $340 per service, which isn’t bad for a premium marque.

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.
