BMW I3 vs BMW 118i

What's the difference?

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 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.

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. 

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.

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. 

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 118i kicks off the BMW 1 Series range from $49,900, before on-road costs. From there you can step up into the warmed over 128ti from $58,900, and the range is topped by the spicy all-wheel drive M135i xDrive in Pure ($67,900) or regular guise ($72,900).

The 118i’s circa-$50K price tag is a lot for an entry-level small hatchback, but it seems BMW has become better at including standard gear in its base variants. But it’s still not what you’d call generous.

Standard equipment in the 118i includes single-zone climate control, a head-up display, LED headlights and fog lights, an 'M aerodynamics' package, leather steering wheel, sports seats, a six-speaker audio system, auto-dimming rear-view mirror, rain-sensing wipers, 'M Sport' suspension, wireless smartphone charging, a 10.25-inch digital instrument cluster, and a 10.25-inch multimedia screen with satellite navigation, digital radio and Apple CarPlay. 

The only option fitted to the test car was premium paint ($1308) which brought the price-as-tested to $51,208, before on-road costs.

So there’s some good tech on the list, but there could be more premium features, you know, given it’s a premium brand, and all. Heated seats would be nice, for example.

Unsurprisingly, BMW offers a number of different options packs ranging in price from $1700 to more than $4000, depending on what you want.

Its two closest rivals are of course from the other big Germans - the Mercedes-Benz A180 (from $49,890) and Audi A3 35TFSI ($47,100) hatchbacks. The level of standard gear is relatively even across the three, although the Audi has the lead when it comes to safety (more on that below), hardly surprising given it's the newest of the three.

There’s also the question of value, especially when you compare with high-grade small hatchbacks from mainstream brands. Models like the Mazda3 X20 Astina ($43,190 BOC), or Honda Civic VTi-LX ($47,200 drive-away) could be good alternatives, or for similar money you could get into something sporty like a Hyundai i30 N Premium (from $48,000 BOC) or for a few grand more there’s the Volkswagen Golf GTI ($54,990 BOC).

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.

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.

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.

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.

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.

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.

The 1 Series range was awarded the maximum five-star rating from crash safety watchdog, ANCAP, in 2019.

The 118i comes with front and rear parking sensors, reversing camera, cruise control, low-speed auto emergency braking, forward collision warning, rear cross-traffic alert, lane departure warning, driver fatigue detection, and six airbags.

It is not fitted with a front centre airbag to help mitigate against injury between the driver and front passenger in a side collision. Only the Audi A3 has this out of the three Germans in this segment.

In this grade, the 1 Series is fitted with regular cruise control, rather than the adaptive system that moderates speed according to the speed of the vehicle ahead. It is a surprise to see the more old-school system in a BMW.

The lane keeping aid works well, smoothly centring the vehicle in the lane when required.

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)

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.
