BMW 1 Series vs BMW I3

What's the difference?

A brief dalliance with the 1 Series has left me impressed, if wanting to spend more time with it to get a better assessment of the day-to-day liveability of BMW’s entry-level model.

It’s a compelling offering if you’re after a premium small car, and even without the performance of the M135, the 118 is feature-packed.

Keeping pricing competitive should help the 1 Series buck the trend of buyers opting for small SUVs, but ultimately it’s just refreshing to see BMW putting effort into keeping a hatchback relevant (and up-to-date).

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

Yes, it’s pricey for a small hatch, but this little BMW is a city car like no other. The i3s is tailor made for the urban environment, and six years on retains the quirkiness and charisma that stood it apart at launch, and it can still hold its head high among the current EV crop. 

The 1 Series has worn many faces over the generations and, like a lot of BMW designs that depart from tradition, this one might need to grow on some people.

That’s not to say there’s not a lot to like about the F70, but as BMW evolves its design language some changes might ruffle feathers - a lack of the iconic ‘angel eye’ headlight style being one.

But there’s still a kidney grille up front, with new design elements, plus those headlights that have a new vertical light signature are now sleeker than before, giving the new 1 a different ‘character’.

But from the rear, there are baby 3 Series Touring vibes, and it’s hard to find anything that might upset purists - there’s even the 'Hoffmeister kink' at the c-pillar. That’s the way the window angles back towards the front at the bottom.

Inside, the 1 Series has some proper sporty elements, even in the 118, that reference the M development that went into it.

There’s M-coloured stitching up over the dash fabric, for example, and illuminated aluminium panels with M-coloured lighting.

The steering wheel, wrapped in leather, is also an M feature, plus sporty seats are even present in the 118.

The interior is an overall cleaner look, in part thanks to the proliferation of features accessible by touchscreen, but BMW is refraining from going full ‘Tesla’ and removing all the buttons from the cabin.

Built around a carbon-fibre reinforced plastic (CFRP) tub, the i3s is ultra-light (for a battery-electric vehicle), super strong, and unlike anything else on the road.

At just over 4.0m long, close to 1.8m wide, and a fraction under 1.6m tall, the i3s is compact, upright, and boxy. A classically polarising design, with some crossing the street to avoid it, and others (like me) loving its unique proportions and stand-out styling.

The nose is tall, short and upright, with the distance from the base of the front windscreen to the front axle (car designers call it the ‘dash-to-axle ratio’) unusually short.

That’s because the electric motor sits in the back of the car driving the rear wheels, with only a small front boot compartment required to house charging cables and other bits and pieces.

Despite the lack of anything of substance behind it, BMW’s signature ‘kidney grille’ is present and accounted for, with swoopy LED headlights (and DRLs) either side. Our test car’s ‘Fluid Black’ finish with ‘i Blue’ highlights dialed up the little car’s charismatic personality.  

One of the i3’s most impressive party tricks is its counter-opening ‘clamshell’ doors, and the engineering trickery used to create a B-pillar free side opening (including the strength of the carbon body structure) means the high window line follows a jagged path from front to back, the rearmost hatch windows shrinking the rear glass area appreciably.

The i3s’s standard 20-inch (dual) five-spoke alloy rims, although slightly wider in this performance model, are alarmingly skinny. But taking the car’s relatively light weight (1245kg) and urban-centric purpose into consideration, the narrow, low-rolling resistance rubber makes sense.

With the roofline and sides of the car tapering distinctly towards the back, the rear view is suitably idiosyncratic, highlighted by flush-fit, vaguely U-shaped LED tail-lights. 

The hatch window is small, and the bumper sits high to marry with the load space floor sitting on top of the motor and transmission.

And when it comes to moving inside, BMW offers a choice of three ‘interior worlds - ‘Loft’, ‘Lodge’, and ‘Suite’ - featuring renewable natural fibres, recycled plastics, naturally tanned leather, and open-pore wood (sourced from 100 per cent Forest Stewardship Council-certified forestry).

But irrespective of where everything comes from, the end result is inviting, comfortable and sub-zero cool. Our car’s ‘Suite’ interior was combined with ‘Oak dark matt’ wood, and ‘Vernasca’ brown leather to stunning effect.

A tunnel-free floor, gently curved dash and digital screens for instruments and media let you know you’re in something different and special. It might be six years old, but the i3 still feels contemporary and distinctive. 

Yes, a brand like BMW would probably find it hard to do away with buttons for things like drive modes and things like volume controls or car settings.

Even though a lot of them are shortcuts to a touchscreen menu, it means not needing to scroll or hunt for important driving-based features and options on the 10.25-inch screen.

Even the climate controls are permanently available on the screen so that there’s minimal distraction.

For most non-essential features, however, BMW’s Operating System 9 is a far cry from the easy-to-use iDrive system of just a few years ago, the media control wheel that fell easily to hand and navigated a simple multimedia system of only a few sub-menus.

Fortunately, the screen and everything in the cabin is within reach of the driver, so there’s no awkward leaning or stretching to do anything mid-drive.

The cabin’s physical space is otherwise nicely laid-out, the phone charger pad is out of the way, cupholders fit most receptacles nicely and the door card can hold two regular water bottles plus other small items.

There’s even a small storage ‘shelf’ under the central vents, and near the wireless charger are two USB-C ports and a 12-volt plug.

The ergonomics of the driving position and steering wheel are well-sorted, and seat adjustment and height feels good for both engaged or relaxed driving positions.

Behind that, the second row could be more spacious, even though I managed to fit my 178cm frame behind my own seating position just fine.

There’s not a lot of room to move or stretch out, so most adults will probably find the back seat suitable for short trips only.

Behind that, there’s 380 litres of boot space, or 1200L with the seats folded down.

Wide-opening clamshell doors make getting in and out of the i3s a breeze. But bear in mind you have to open the front door to get to the latch for the back one, which can be a pain.

The driver and front passenger enjoy heaps of room, in an open environment, but there’s only a single cupholder in the centre console, so let the coffee cup wars begin.

Aside from that there are seriously big bins in the front doors, a modest glove box, and a handy elasticised pocket near the floor at the base of the bulkhead.  

Outlets for 12-volt and USB are provided, and there’s a small oddments tray at the rear of the centre console.

Slip around to the rear and you’re in anything but limousine territory. Sitting behind the driver’s seat set for my 183cm height, head and legroom are modest but do-able. And remember it’s two seats only back there.

In terms of storage, there are two cupholders between the seats but no storage pockets or bottle holders in the doors. You won’t find adjustable ventilation outlets either, but that’s not a huge factor in car of this stature.

The boot’s volume is quoted at 260 litres with the 50/50 split-fold rear seatback upright, which is enough to easily swallow the largest 124-litre suitcase in the CarsGuide three-piece set. The smaller 95- and 36-litre cases will sit side-by-side without a problem.

Fold the rear seat down and you have 1100 litres of space at your disposal, with tie-down anchors, an elasticised pocket and 12-volt power provided.

Don’t bother looking for a spare of any description, a repair/inflator kit is your only option. And not surprisingly, the i3 is a no-tow zone. 

For a compact, four-seat hatch the BMW i3s is all the money at $70,900, before on-road costs. Close to $20K more than even the top-spec ‘Premium’ version of Hyundai’s Ioniq electric hatch ($52,490), and even further away from Renault’s cute little Zoe ($49,490).

But a carbon monocoque body and high-tech powertrain don’t come cheap, and that’s where BMW’s ‘i’ model program has seemingly run out of juice.

Getting into the EV market early, BMW took a punt on niche vehicles using exotic materials, appealing to a relatively small group of premium buyers. And in glorious hindsight, that path has proved something of a dead end.

But putting all that to one side, it’s fair to expect a generous standard equipment list in a $70K-plus BMW, and the i3s comes to the party with a solid, if not spectacular batch of features. 

Aside from the safety tech detailed later, Included is a 10.25-inch media touchscreen, managing audio, built-in nav (with real time traffic alerts), phone connectivity and more.

Other features include, wireless phone charging (for compatible devices), a rear-view camera, automated parking assist, active cruise control (with stop-go function), climate control air, driver’s digital display, ambient interior lighting, 20-inch alloy wheels, auto LED headlights, LED DRLs, indicators and tail-lights, keyless start, rain-sensing wipers, plus heated and folding power mirrors.

But there are a few surprises. It might be an electric car, but forget power adjustment of either front seat. And despite inclusion of Apple CarPlay (BMW says Android Auto will be available later in 2020) and digital radio, the audio system only has four speakers, all in the front doors (because of the clamshell arrangement detailed later). 

Our test car featured the ‘Suite’ interior package ($2308) which brings ‘Vernasca Dark Truffle’ leather on the seats, instrument panel, doors and side trim, as well as ‘Oak dark matt’ wood trim, the steering wheel in black with a ‘Satin Silver’ contrast ring, floor mats (and general interior fabrics) in ‘Anthracite’, the roofliner in ‘Carum Spice Grey’, plus orange/white LED lighting for the door pull handles and front map pocket. A dual porthole-style glass sunroof adds another $2246, for an as-tested price of $74,454.

The two 1 Series variants have rather different running gear.

The 118 comes with a 1.5-litre three-cylinder turbo petrol engine that drives the front wheels via a seven-speed dual-clutch transmission (DCT).

It makes 115kW and 230Nm, and BMW says it’ll hit 100km/h in 8.5 seconds.

That’s in comparison to the beefier 2.0-litre four-cylinder unit in the M135, also turbocharged, but driving all four wheels via a similar seven-speed DCT.

It makes 233kW and 400Nm, and it’ll crack 100km/h in 4.9 seconds according to the Bavarian brand.

The i3s is powered by BMW’s ‘eDrive’ hybrid synchronous electric motor, producing 135kW at 7000rpm, and 270Nm from 0-4500rpm. Yep, that’s right, maximum torque is delivered the instant you depress the right-hand pedal, and we’ll get to what that brings to the driving experience a little later.

The unit incorporates a charging and generator function for braking energy recuperation, the latter delivering up to 50kW.

Drive goes to the rear wheels via a single-speed (fixed-ratio) automatic transmission.

The battery powering the whole show is a 352-volt/120 amp-hour (Ah) Lithium-ion unit with a (gross) energy rating of 42.2kWh.

BMW says the 118 will sip 6.4 litres of recommended 95 RON fuel for every 100km covered, with its 49-litre tank the same as the M135’s.

In that variant, fuel use increases to 7.8L/100km, as does recommended fuel quality to 98 RON.

We didn’t get a chance to test fuel consumption properly on the launch, so keep an eye on a future review for that, but given the relatively high claim even for the 118, we’d expect the 1 Series isn’t the most frugal drinker.

When it comes to an electric car’s energy use and projected range, there are two main things to consider - the motor’s power consumption and the battery’s capacity.

And according to BMW, the i3s’s power consumption for the combined (urban/extra-urban) cycle is 14.6–14.0kWh/100km.

Over a week, and roughly 250km of urban driving (with some brief freeway runs thrown in) we saw 19.3kWh/100km staring back at us from the on-board computer.

When BMW launched the i3 in Australia in 2014, the pure EV version came with a 60Ah battery pack delivering a claimed 130 kilometre range (a range extender model featuring the addition of a two-cylinder petrol motorcycle engine was also offered). 

In 2016 a 94Ah version arrived to boost range up to 183km, and the i3s launched in 2018, with its 120Ah battery pushing range out to BMW’s current, real-world estimate of 260km.

Then, there’s charging time, which is like asking how long is an electric piece of string.

According to BMW, for a 0–80 per cent charge from a (50 kW DC) fast-charging station, you’re looking at 45min.

From a (11kW/16A/380V) high-output home/office wall unit, that pushes out to 3.10h, and using a (3.7kW/16A/240V) low-output home/office unit stretches the wait time to 9.40h.

BMW offers the ‘WallBox plus’ charging suite as a dealer accessory priced from $1990 (not including GST or install costs).

Plug into a domestic (2.4kW/10A/240V) socket, and you’re staring down the barrel of 15.00h. But at least you can use low-cost, off-peak energy overnight, right? Nah, I don’t buy that line either.

The launch drive for the 1 Series included some outer-suburban Melbourne traffic, a stint of highway driving down towards the Mornington Peninsula, and a semi-rural road loop for each variant before the return journey.

So, noting that we didn’t quite get the chance to really work out what it might be like to live with the 1 Series day-to-day, first impressions showed good signs.

Both variants still drive much like you’d expect from even a front-drive BMW, let alone the AWD M135, but the chassis and suspension seem like they’d be good counterparts on a daily drive.

In the M135, communication and compliance seemed well-balanced with each other for even some particularly rough surfaces, and after torrential rain there were some potholes that would properly upset most cars that didn’t faze the 1 Series too much.

The 118 seemed to let a little more road noise into the cabin, but that might have been a symptom of different road surfaces.

The steering is accurate, but the feel in both is a little heavier than needed, especially with the thick-rimmed BMW steering wheel that you’ll know about if you’ve driven anything from Munich in recent years.

It’s a very easy car to drive fast, especially with the combination of 233kW, 400Nm, and all-wheel drive at the M135’s disposal.

The chassis and tyres work quite well together to not only hold a corner at impressive speed, but also keep the car stable so that traction isn’t an issue when launching out.

There’s also the joy of hearing a turbo spool and flutter under load, which is hard to deny as a draw for petrolheads.

It might not look like a conventional sports car, but the BMW i3s certainly accelerates like one, with a claimed 0-100km/h time of 6.9sec. The i3s is a smile-inducing hoot to drive.

Every one of this little hatch’s 270 newton metres of torque is available from the minute you hit the accelerator pedal, and remain in service until 4500rpm, at which point torque delivery drops off a cliff.

But peak power steps in at exactly 7000rpm, so if you’re determined to make that overtaking move you won’t be left in the lurch. In fact, BMW says it only takes the i3s 4.3 seconds to surge from 80km/h to 120km/h.

However, the i3’s forte is 100 per cent the city, rather than the open road. Its ‘point and squirt’ ability making it the perfect partner for the cut and thrust of the urban jungle.

The i3s features an upgraded ‘Sports Suspension’ incorporating firmer dampers, re-tuned springs and revised anti-roll bars. It’s also lowered 10mm, the track is widened (+21mm front / +2.0mm rear) and the wheels go plus one inch to 20-inch alloys.

The standard i3 (no longer offered in Australia) rolls on 19-inch rims shod with 155/70 rubber all around. And while the i3s’s 175/55 front and 190/50 rear tyres are still exceptionally narrow, from the side the low-profile Bridgestone Ecopias look like fan belts wrapped around pulleys rather than tyres around wheels..

No surprise then that ride comfort isn’t exactly cushy, and in signing on for the i3s experience you’ll need to be ready for more than occasional bumps and thumps.

But the pay-off is super-sharp dynamics, Suspension is by alloy struts at the front, and a five-link alloy set-up at the rear..The steering responds to inputs quickly yet smoothly, and with 48/52 front to rear weight distribution, the car always feels balanced, eager, and taut.

And if you really want to dial things up the ‘driving experience control’ allows a switch to Sport mode for a further tweak of the suspension, steering, and traction control set-ups.

A tight 10.3m turning circle makes for easy parking and stress-free U-turns. But if things get too tight, rapid three-point turns are assisted by the gear shift controller bring mounted on a chunky stalk on the right-hand side of the steering column. Too easy.   

Braking is by vented discs front and rear, but they’re tiny. That’s because the ‘Brake Energy Regeneration’ system does most of the work. 

Effectively turning the motor into a generator, the system not only slows the car dramatically but feeds energy to the battery in the process. It takes a while to get used to the sensation, but soon becomes a fun, and surprisingly easy game to use the brake pedal as little as possible… often not at all, for long periods.

The i3 scored a maximum five ANCAP stars when it was assessed at the time of its local launch in 2014, and the standard safety spec has been boosted since then.

Active tech includes ‘the usual suspects’ such as ABS, EBD, and ESC, as well as city-speed AEB (with 'Forward Collision Warning', and  'Traffic Sign Recognition'). reversing collision avoidance, a reversing camera, and tyre pressure monitoring.

If all that doesn’t prevent an impact, passive safety tech includes, dual front, side chest and side curtain airbags.

There are also top-thether points and ISOFIX anchors to secure child seats/baby capsules in both rear seating positions, as well as a first aid kit and warning triangle..

BMW’s got a fairly standard five-year/unlimited kilometre warranty.

The brand also uses a condition-based servicing system, which uses the multimedia to alert the owner when maintenance is required.

There are servicing packages which remove some of that uncertainty, in the 1 Series’ case a five-year, 80,000km pack costs $2210.

BMW offers a three year/unlimited km warranty, which is off the pace given the majority of mainstream brands have stepped up to five-year cover, with some at seven. And the pressure is on with Mercedes-Benz recently announcing its shift to five years/unlimited km.

That said, the BMW's body is warranted against rust (perforation) for 12 years/unlimited km, and roadside assistance is provided free-of-charge for three years/unlimited km.

Maintenance is 'condition based' with sensors and on-board algorithms (mileage, time since last service, driving style) determining whether an annual vehicle inspection is required.

The 'BMW Service Inclusive' package, offering a single, one-off advance payment to cover selected service and maintenance costs, is available in two levels - 'Basic' ($850) or 'Plus' (dealer quote)
