BMW M140I vs Mercedes-Benz Glb200

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.  

The GLB is set to mix up the Australian premium small SUV landscape by launching something a little different to most of its competitors. It's bold and interesting to look at, which is a good sign for a brand that's spent the last few years going to great pains to homogenise the styling of its main models.

Importantly, it manages to look interesting and drive well, while living up to an ambitious practicality promise.

Whether consumers warm to it or not will largely depend on its standard specs in Australia, so stay tuned closer to its second quarter 2020 launch to see exactly how competitive Benz can make its not-so-small small-SUV...

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 GLB is ugly... in a good way. I think so, anyway. It shuns the slick lines of the GLC, and Benz sedan family in favour of something unusual.

You'll notice straight away the chunky lines and upright front and rear fascias of the GLB, along with its light fittings that are wrong, but also right?

Then there's the shutline of the bonnet which rides across the top, creating a distinct off-set line, which is rudely interrupted by a jutting bit of chrome over the rear wheel arch.

It's almost so intentionally jarring that it feels like it's meant to conjure up visions of a mini G-Class. Benz says many of these design elements were internally dubbed 'squircles' due to their blending of angles and curves.

There's a lot to look at, and admittedly I wasn't initially a fan, but like many new design languages, you have to see it in the metal to appreciate it. I found it only became more endearing with time.

Just like the rest of the Benz compact vehicle family, the GLB has a new interior full of screens and round design elements. If you're a fan of the A-Class' interior you'll be a fan of this, too, although the GLB even ups the quality with some genuinely nice materials strewn about the place.

Special attention was paid to things like the little tubular metal fittings in the dash and doors, meant to represent grab handles and the LED lighting on higher spec cars reflected inside the air vents is always one of those wow factor items.

The dual 10.25-inch screen set-up is controversial. Some will love it, some will be begging for a set of analog dials.

Once you've adjusted to it though, it's relatively easy to use – with a couple of caveats we'll explore in the practicality section.

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.

The GLB's thematic purpose in the Benz family is to be the practical option to the upcoming GLA's 'sportiness' and larger GLC's luxury. Although it's not that much smaller than the GLC, the GLB is packaged in a radically different way.

For one, it can be had as a seven-seater, and at this size there's not much that can compete in the luxury space. Again, that makes its closest rival the Land Rover Discovery Sport which is dimensionally similar and also offered with seven seats.

The next closest seven-seat competitors come in the form of the VW Tiguan Allspace and perhaps Skoda Kodiaq.

Audi and BMW don't quite have anything like it (despite fielding a Q2 and Q3 or X1 and X2 respectively... ), and that could well be the GLB's master stroke. It almost fills its own niche. Mercedes is heavy on the idea that this will be the perfect SUV in its line-up for growing families.

Like those VW group rivals, the GLB is a bit of a practicality wizard, too, able to make use of a huge 500-litre boot with the rear seats stowed, or 570 litres as a five-seater.

The second row is on rails, so you can either max legroom or max boot space respectively. I was genuinely surprised with how spacious the third row is.

The packaging is brilliant, I can fit in there, not only with my head completely upright (just touching the roof), but also with actual knee room! The second row seats are also designed as such that your feet can tuck under them, so you don't feel squashed.

Even with another adult in the rear row it's wide enough to not cause problems.

Keep in mind though, with all three rows deployed you'll almost be sacrificing 100 per cent of that massive boot. I couldn't even fit a basic duffel bag in the shelf of space left over.

The second row offers simply heaps of legroom for passengers, even with adults in the third row, and it's surprisingly wide and deep. I found the panoramic sunroof, fitted to some launch cars, ate into the headroom, although it was still more than enough.

Up front is upright, but comfortable in all grades, with the GLA 35 having the most comfortable seats, by far. There are a few trenches strewn about the place, decent cupholders and a centre console box which hosts USB ports.

Trim quality was a notch above the A- and B-Class across the dash, mainly thanks the the choice of materials in the GLB's design.

I do have a few minor issues with visibility though. The A-pillar is upright and, at times, takes up too much of your line-of-sight, especially when approaching corners.

In my seating position, the top of the steering wheel obscures bits of the digital dash, and vision out the back was okay but not stellar thanks to the GLB's almost flat rear window.

Benz' digital dash suite is capable of almost everything that Audi's benchmark 'Virtual Cockpit' does, although using it is a bit awkward, with many sub menus and odd touchpads for flicking through them on the steering wheel.

We don't know how much the GLB will cost when it comes to Australia, but Mercedes says to expect it to fall in a sensible void between its GLA (currently $44,700 - $94,382) and the GLC ($66,100 - $168,100).

Its traditional competitors will mainly be in the form of the BMW X1, and Audi Q3, although size and spec wise it's much closer to the Land Rover Discovery Sport (from $60,500) which can also be had with seven seats.

While standard inclusions on the Euro cars as tested here were decent, we expect they will increase for base Australian cars, along with a price hike.

Prices will largely depend on the choice of engine grade and out of the six options available globally, Australians will only be offered three petrol powertrains (Mercedes has decided against bringing the three diesel options to our market, citing a relative lack of demand).

Of course, option packs will transform each car, and there are many of them, but there are some revealing downfalls in the internationally specified cars. LED headlights, lane keep assist, and blind spot monitoring are part of an option pack in Europe. We hope these items, or at very least blind spot monitoring, is added to the standard features list for Australia.

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 GLB has an almost confusingly extensive list of engine options. In Europe it's offered with three petrols and three diesels in either front- or all-wheel drive.

We'll only address the petrols as they are the only units destined for our market. The entry-level car is the GLB 200 which has Mercedes' familiar 1.3-litre four-cylinder turbo engine (120kW/250Nm) shared across the A- and B-Class, as well as various Renault models. In this case it's mated to a seven-speed dual-clutch automatic.

Next up is the GLB 250. The 250 is a 2.0-litre engine with significantly higher outputs (165kW/350Nm). It is offered only with Benz' '4Matic' all-wheel drive. It is offered with an eight-speed dual-clutch auto only.

Then there's the star of the petrol-powered show, the GLB 35 AMG. Powered again by a 2.0-litre engine, the AMG-tuned GLB ups the ante to 225kW/400Nm. It is offered with an AMG tuned eight-speed auto, and adds the 'Sport +' drive mode.

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.

Fuel consumption figures are as varied as the engine choices, the base GLB 200 will consume 6.2L/100km on the combined cycle, while the GLB 250 adds more than a litre to that number at 7.4L/100km, and despite its performance focus, the GLB 35 will supposedly do 7.6L/100km on the combined cycle.

Real-world figures will have to wait until we get our hands on Aussie-spec GLBs to do a fair week-long test. Stay tuned for that.

It is yet to be confirmed, but we'd be surprised if the GLB required anything less than 95RON mid-grade unleaded petrol.

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.

Driving the GLB was surprising. It's comfortable! It doesn't seem to matter which grade you pick, either. In fact, the GLB 35 rides the best, with its ridiculous wheels overcompensated for by impressive active dampers.

Families will love the plush seats and ultra-compliant ride. Some Benz magic must have gone into the suspension calibration, but we think the ride is also helped along by the long wheelbase.

The position of the wheels also helps prevent the GLB from feeling too nose happy. You don't feel at risk of understeer at all, and this is probably due to the fact that the front wheels are actually quite far ahead of the A-pillar.

In terms of handling, the GLB is great. The steering is light, but direct in Comfort mode. Sport mode is more of a mixed bag, with the wheel feeling a bit too artificially heavy. In 'Individual' mode you can set it up to have the suspension and transmission set to Sport, with the Comfort steering.

Obviously the GLB 35 is a hoot in terms of power available. It's fun, if a little silly. I was surprised how sedate the exhaust is, even in Sport +, a show-pony the GLB 35 is not.

That goes for all grades, too. The cabin is generally well refined.

The 250 is the right car for most drivers, with plenty of power on tap, and a reasonably smart eight-speed dual-clutch. This transmission's major drawback was how annoying it was in Sport mode, sticking in gear and revving the engine out unnecessarily.

Surprisingly, we also had the chance to sample the base model 200. This car rode just as well as its higher-spec counterparts, and it was just as quiet, too, but the 1.3-engine took a long time to get to its sweet spot.

The extra weight of the GLB over the A-Class and B-Class was evident, and the seven-speed auto seems a little less intelligent and slick-shifting than the eight-speed on the other two grades.

There was a long waiting time for peak torque, meaning foot to the floor for several seconds before anything really happened.

That having been said, the 200 is still an attractive option to cut the cost of a GLB for someone who will mainly use it for city or urban driving.

Which leads to one of the GLBs drawbacks – it doesn't feel like a 'small' SUV behind the wheel. You feel every last bit of its dimensions when negotiating a three-point turn with its almost 12-metre turning radius or trying to navigate tight city streets.

Overall though, the GLB offered a surprisingly comfortable, quiet and even entertaining drive experience for an SUV.

Thanks to those kooky Germans and their love for high-speed freeways, every GLB will ship with high-speed auto emergency braking with standard pedestrian and cyclist detection.

It also gets lane departure warning (delivered by vibration through the steering) and a limited version of lane keep assist that works on solid lines and helps swerve away from oncoming vehicles.

Additionally via an option pack on the Euro cars we tested is 'Pre-Safe Plus' which adds blind spot monitoring, improved lane keep assist with lane change assist, and a system which uses a rear radar to detect incoming collisions and lessens the risk of whiplash.

We don't know what will be on Australian-specified cars yet, so stay tuned for an update.

The GLB has a total of six airbags, and in case you're wondering, the GLB's side curtain airbags are capable of protecting even the third row.

ISOFIX and top-tether chid seat mounting points are available on both the outboard seats in the second row, and in the third row in seven-seat variants – for a total of four child seat ready positions.

We'll have to wait and see what ANCAP rating the GLB scores (with standard safety equipment for this market to be confirmed), although it already wears a maximum five star Euro NCAP rating.

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.

Like Audi and BMW, Mercedes persists with a three-year/unlimited km warranty. If you believe BMW, they say consumers in this price bracket don't expect longer warranties, but it would be nice, no?

The first German to do it will win a distinct advantage, but for now the GLB's warranty promise is par for the course.

Service pricing has not been plotted out for the GLB in our market yet but expect to be able to package in several years at a fixed price on finance, as you can on other Benz vehicles.
