BMW 118i vs BMW 1 Series

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.

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.

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.

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.

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.

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.

The 1 Series isn’t much more expensive than before, despite a decent uptick in kit.

At $56,500 before on-roads for the entry grade 118, it’s less than $2000 pricier than its predecessor. It’s about the price of a VW Golf GTI or Subaru WRX, but trades engine power for badge power, as well as a series of features you’d expect from a premium small car.

A 10.25-inch multimedia touchscreen and 10.7-inch driver display are standard, with wireless phone charging, electric heated seats in Veganza synthetic leather, adaptive suspension and plenty of sporty styling thanks to the M Sport pack.

There’s a few more helpful features for keen drivers, even in the 118. Adaptive LED headlights with high beam assist, a head-up display, BMW’s 'Parking Assist Plus' function, speed limit recognition and tyre pressure monitoring.

The 1 Series also has keyless entry and start, an automatic tailgate, plus some standard stuff like a 40/60 split-fold rear seat and (unfortunately) a tyre repair kit under the boot floor rather than a spare tyre.

Then there’s the M135 xDrive, the hot hatch of the pair.

It starts at $82,500 and comes with extras like a massage seat for the driver, a heated steering wheel, a Harman/Kardon sound system, racier styling and a black roof, plus performance goodies like a bigger engine.

The M135 is a bit more expensive than before though, by almost $6000, and comparable rivals like the Audi S3 remain in the mid-$70K range.

Two options packs are available, with the 118's $5000 Enhancement Pack adding Metallic paint, 19-inch M alloys, a heated steering wheel, a sunroof, massaging front seats, a Harman/Kardon sound system and Driving Assistant Professional.

There's also an M Sport Package Pro able to be added to either variant, which adds sportier M styling, a black roof for the 118, and M Sports seats for the front row. This pack costs $2462 for the 118 or $2700 for the M135 xDrive.

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 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.

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.

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.

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 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.

There’s plenty of active safety in the new 1 Series, new kit includes an updated 'Driving Assistant Plus', BMW calls it.

It features all the driving assist functions like lane departure warnings and rear cross-traffic alert, but the M135 gets a higher-spec version with extras like front cross-traffic alert, side collision prevention, and evasion assist.

This can be added to the 118 for $5000 in the Enhancement Package, but it seems a bit stiff to put safety features behind a paywall alongside items like a sunroof and a high-end audio system.

Mercifully, the 1 Series’ active safety systems are all pretty unobtrusive. There are very few ‘bings and bongs’ as we’ve come to call them, and any warnings are generally subtle.

There’s a quick way to turn most of them off via a physical button near the gear selector, and its adaptive cruise control is well tuned for urban, highway and rural driving.

Otherwise, the third-gen 1 Series scored five stars with ANCAP in 2019, so we will wait and see if its successor maintains that score.

It’s also got six airbags including front and side, as well as curtain airbags covering both rows.

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.

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.
