BMW M140I vs BMW 1 Series

What's the difference?

I’m the first to say the 1 Series is kind of the ugly duckling of the BMW family, but those looks grow on you, especially when you consider that this is exactly what a BMW hatch should look like. That this is one of the only rear-wheel-drive hatches left on the planet makes it even more special – and of course engaging to pilot. The downside is the price and the lack of value from a features perspective, plus safety could be bolstered with more technology. Still, anybody who likes to drive will commend you on your choice of a BMW.  

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.

The 1 Series looks exactly how a BMW hatchback should. I know that sounds silly but what I mean is BMW could easily have designed something that was proportioned more like other hatches; that popular sort of bubble on wheels.

Instead, what you have is a hatch that retains BMW’s traditional attributes – there’s the long nose, the cabin set back, the high sides and the wheels placed almost at the very corners.

Seriously, look at the image of the orange 1 Series side on, now hold your out your hand and use it to cover just the windows – see, it looks just like a BMW 2 Series convertible. Does it look good? To me it does, right up until you get to the hatchback, and then it looks a bit awkward. But I do admire BMW’s designers for creating something unique looking.

That orange 120i ('Sunset Orange' is the official colour) is the most recent 1 Series I’ve tested. Those wheels aren’t standard, they’re 18-inch M ones and they are part of the optional 'M Sport Package', which also includes the body kit, complete with side skirts and the lower grille in gloss black.

The 1 Series is as affordable as BMWs get, but it’s still a real BMW. The cabin, for example, looks much like  every BMW, only smaller.

There’s the large, slab-like dash with the display sitting atop, below are the air vents and below that is the radio and then the climate-control dials. It’s a stack that’s kept its familiar order and shape on nearly all BMWs for what seems like forever.

The centre console has a similar layout as the one in a 3 Series or 5 Series or any Series, with the shifter and rotating media controller. Even the doors have the same design as those cars higher up in the BMW family, with the big moulded pockets and large pull handles.

The cabin isn’t as ‘blingy’ as the new Mercedes-Benz A-Class, but it’s not as plain as the Audi A3.

That steering wheel is part of the M-Package too, but the leather upholstery is a separate option.

The signs that this isn’t a more expensive BMW are the manual handbrake, the compact instrument cluster with analogue dials, the small dash-top display and the fact that  there’s a lot less real estate to be covered by trim pieces and material, which doesn’t have the same high-quality feel as those fancier models.

The cabin isn’t as ‘blingy’ as the new Mercedes-Benz A-Class, but it’s not as plain as the cockpit of an Audi A3 – it’s somewhere in between; refined and well designed.

At 4.3m end to end, the 1 Series is 16mm shorter that the A3 Sportback and 20mm narrower, at just over 1.7m across.

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.

The 1 Series’ boot has a cargo capacity of 360 litres, which is more than the boot space of the Audi A3 Sportback (340 litres) but less than the new Mercedes-Benz A-Class’s 370 litres of luggage room.

What does that mean in real-world terms? It’s not a lot of space, and you might struggle to get a pram in, so check that  beforehand if you have small ones. That said, there was enough room for two carry-on sized bags, a computer bag and a scooter when my wife and I went on a weekend away with our four year old.

Space in the second row is also limited. Headroom isn’t too bad, but at 191cm tall I can’t sit behind my driving position without my knees digging into the seatback. I can just fit back there in the A3 and I have even more room for my knees in the A-Class.

Room up front is good with plenty of shoulder, head and elbow room for somebody my size.

Storage could be better: you’ll only find cup holders up front (two of them), the centre-console storage bin is small and so are the door pockets in the rear, but all is not lost because the door bottle holders in the front are massive, the glove box is a decent size and there are nets on the backs of the front seats.

It’s good to see directional air vents in the second row and a 12V power outlet, but there aren’t any USB ports back there – if you want to plug in a device there’s only one and it’s up front, along with another 12-volt outlet.

The rear doors appear large from the outside but the aperture to get in and out isn’t huge – again look at the images to see what I’m on about.

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.

As you step up through the grades the engines become more powerful. The entry-grade 118i has a 1.5-litre three-cylinder turbo-petrol making 100kW of power and 220Nm of torque, while its diesel twin has a 2.0-litre turbo-four making 110kW and much more torque at 320Nm.

The 120i has a 2.0-litre turbo-petrol four-cylinder and an output of 135kW and 270Nm. Then above that is the 125i, which is getting into performance territory with its 2.0-litre turbo four petrol making 165kW and 310Nm.

But all hail the M140i and its beautiful 3.0-litre six-cylinder turbo-petrol, with 250kW and 500Nm that it wants to share with you.

All cars are rear-wheel drive and all have an eight – hang on, that’s important: all cars are rear-wheel drive. Do you know how many other hatchbacks are rear-wheel drive? Try next to none – not the A-Class, not the A3, not the Golf. Rear-wheel drive is favoured for performance cars because it offers better balance and better acceleration thanks to the weight shift to the rear of the car. BMW has long claimed that RWD is one of the keys to its "sheer driving pleasure".

Now let me finish the sentence... all have an eight-speed automatic, and it’s a beauty – a little slow, but smoother for driving than a dual clutch, and way more fun than a CVT.

But wait, because there’s a manual gearbox, too. It’s a no-cost option and you can get it on any variant apart from the 125i.

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.

BMW says its most efficient petrol engine in the 1 Series range is the three-cylinder in the 118i, which uses just 5.2L/100km after a combination of urban and open roads.

The diesel unit in the 118d will use 4.2L/100km. Let that sink in for a moment – petrol engines are becoming so fuel efficient that they’re rivalling diesels, which have long been lauded for their frugality.

So don't just buy the diesel just because it’s more efficient, because you may never recoup the extra money you paid over the 118i.

Thirstier but still super-efficient is the 2.0-litre in the 120i. BMW’s claim is 5.9L/100km. During my week with the 120i I put 413km on the clock and used 15.57 litres doing so (measured at the pump), which comes to 7.7L/100km. The car’s computer said 7.8L/100km.

That’s great fuel economy, even if it is higher than the claimed figures. The 125i’s official fuel consumption is also 5.9L/100km.

It’s not surprising that the M140i, with its 3.0-litre six-cylinder turbo-petrol engine, is the least fuel efficient but its official figure of 7.1L/100km is still low.

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.

If I could run into a showroom and take whichever 1 Series I wanted it’d be the M140i – and not just because it would give me the best chance of outrunning the police after they discovered the break-in, but because the thing is so much fun to drive.

It’s also the most expensive, of course, but it’s worth it for that screaming straight six and for its agility.

You’ll have fun, though, in every grade of the line-up – they’re all engaging to pilot with great driving positions, good pedal feel and that eight-speed auto is smooth in traffic yet will shift hard when you have your race face on.

You might find the 118i, with its three-cylinder, a little under powered, especially with five people and their bags on board. If you’re keen on this grade, then consider the diesel, which will give you more torque. Our 120i test car proved to have enough oomph for overtaking and moving quickly when needed.

The 125i is less tame, with its throatier exhaust note, firmer ride and better handling thanks to the M suspension.

If you plan on choosing the M Sport Package for, say, the 120i keep in mind that you’ll lose the comfortable ride these cars have on their standard tyres.

Our 120i had the pack and while the body kit looks tough, the 18-inch alloy wheels shod in low-profile rubber (225/40 R18 Bridgestone Potenza 5001s front and 245/35 R18 at the rear) meant the ride was overly jarring on bad roads.

Given that Sydney was my test bed for the 120i and its roads are shocking, the ride was less than comfy. The M-sport suspension will only make the ride less comfortable, but in return you’ll have a 120i with better handling.

Run-flat tyres are common on BMWs and you may have heard of a few issues surrounding noise and a harsher ride. While that can be true, it's the price you pay for having a tyre you won’t immediately have to change if you get a puncture. Only the 120i and the M140i don’t have run-flats as standard.

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.

The 1 Series is covered by BMW’s three-year/unlimited kilometre warranty. Servicing is condition-based – the car will let you know when it needs a check-up.

BMW offers two service packages, which cover the car for five years/80,000km: the Basic is $1340 and the Plus costs $3550.

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.
