BMW M135i vs BMW 118i

What's the difference?

To answer the question of whether it matters that the new 1 Series is no longer rear-wheel drive, I say no it doesn’t. It may not be as romantic on the absolute limit, but it is better in every measurable way, and still feels distinctly BMW despite moving to the conventional layout of its rivals. 

Be sure to check out Mal’s video review from the 1 Series launch last December:

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.

Yes, that kidney grille is rather large. If you want everyone to know you drive a BMW, you’ll love it. If not, get used to it. The X7, recent 7 Series update and upcoming 4 Series suggest they’re only going to get bigger. 

Nose aside, the 1 Series hatch has always had a distinctive, long-bonnet profile, which has generally been attributed to the rear-drive layout. Despite the move to a transverse engine, the new one is actually very close in proportions when compared side by side.

It’s just 5mm shorter in overall length and 13mm taller, with body width being the most notable change at 34mm wider. 

The key difference is that the front and rear wheels have been moved further back into the body, because of said engine layout change, and to make more back seat space in the rear.

Surprisingly for a model aimed at a younger demographic, the new 1 Series interior design isn’t quite the same step forward as the recent G20 3 Series.

It’s a cut above the X1 and X2 SUVS the new 1 Series shares its underpinnings with in terms of the shapes used, but is still classic understated BMW. 

However its headline act is the Live Cockpit driver display on both models, which gives you fully digital instrumentation and replaces traditional analogue gauges once and for all.

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.

With my modest 172 cm height, I never had any trouble with the old model, but the new 1 Series is a bit more more spacious by all the important measures.

The back seat base and backrest are a bit flat though, which is probably to help the backrest fold almost flat, but probably not very supportive during hard cornering.

There's also no centre armrest in the back or cup holders, but you do get bottle holders in the doors.

You also get two ISOFIX child seat mounts and there’s two USB-C charge points in the back of the centre console, but there's no directional air vents unless you opt for the dual-zone climate control that comes standard with the M135i. 

The boot has grown by 20-litres to a pretty impressive 380 litres VDA which includes a very useful cavity under the floor instead of a spare tyre. An inflation kit is there for those duties. With the back seat folded flat, boot space expands to 1200 litres VDA. 

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).

Both cars use versions of the three and four cylinder petrol engines from before, with the popularity of automatics leaving the previous manual option consigned to history.  The 118i’s 1.5-litre turbo three cylinder now produces 103kW/220Nm, with max torque available all the way from 1480-4200rpm. The 118i now uses the seven-speed dual clutch automatic transmission, as seen on Mini models that use the same engine. 

The M135i’s 2.0-litre turbo has been tweaked to take the place of the six-cylinder M140i from the last model and now produces 225kW/450Nm, with max torque available all the way from 1750-4500rpm. Its auto remains a torque converter though, but now the transverse-mounted unit also shared with Mini models with the same engine and splitting drive to all four wheels via the xDrive system for the first time. The drive split is constantly variable, but the rear bias tops out at 50 per cent and the only limited slip diff is an electric unit on the front axle.

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.

Official combined fuel consumption is a decent 5.9L/100km with the 118i, but the M135i steps up to 7.5L/100km) 2.0 litre four in the m135i. Both engines require premium unleaded. 

Fuel tank sizes vary across the two models also, with the 118i measuring 42 litres and the M135i managing 50 litres, despite its need to package rear drive components somewhere under there also. 

This results in a decent theoretical range between fills of 711km for the 118i and 666km for the M135i. 

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.

For a brand with a marketing slogan of pure driving pleasure, this is the important part, particularly given the new 1 Series has lost its rear wheel drive USP. 

Why do some of us love rear wheel drive? It tends to be more fun when you're driving on the limit, and generally makes for nicer steering because you're only using the front wheels to turn corners.

So how does the new 1 Series drive? That depends on which version. 

The 118i is quite a nice package really. It rides a bit more gently than what I remember in the A-Class and generally feels more like a premium product. It also feels a step ahead of the 2 Series Active Tourer it shares its underpinnings with, which is a good thing.

The three-cylinder engine is quite smooth for a fundamentally unbalanced triple, and it makes enough power to get you out of trouble. 

Do you miss rear wheel drive? Not really, as you can only tell the difference when you're going real fast, which let's face it, is not somewhere 118i drivers are likely to go very often. 

The M135i is a vastly different beast, as you'd expect. Aside from being real quick, it's that much tighter everywhere, but still definitely on the more comfortable side than what we expect the future full house M version to be.

The continuously variable xDrive all-wheel drive system does a great job of putting its power down, but the rear bias maxes out at 50 per cent, which is probably spot on for chasing lap times, but means you miss out on the tailiness of the old one altogether. 

So it’s not as classically fun as the old M140i, but it’s easily faster, and that's what will probably matter most to most buyers. 

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 is yet to step up to the five year warranty offered by most mainstream brands and now Mercedes-Benz and Genesis, continuing with the three year/unlimited coverage matched by Audi. 

As always, BMW describes the service intervals as condition based, and the car will alert the driver when a service is due. This will occur at least every 12 months though, but individual intervals will vary based on how the car is driven. 

This can all be bundled into five year/80,000km service packs though, with the Basic pack costing $1465, but the Plus pack adds brake pad and disc replacement to regular fluids and consumables for $3790. Assuming 12 month intervals, these prices are about average for a premium branded product. 

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.
