What's the difference?
Mercedes-Benz reckons its A B Cs are as easy as a competitor's 1 2 3s, which is why it's adding an all new nameplate to the world's ever-expanding list of premium small SUVs.
What you're looking at here is the GLB, and as the name implies – it's the latest addition to the Deutsche juggernaut's 'compact' family. Mercedes is a little late to the show, though, with its main competitors, Audi and BMW, already offering two small SUVs each.
Not to be outdone, Merc's GLB is a totally different take on the small premium SUV formula, especially since, well, it's not all that small...
Read on to find out what that's about, as well as what we made of the GLB at its international launch.
Meet the IM6 Performance, “presented by MG”. And that last bit’s important, because while it’s marketed and sold by the Chinese mainstream player, it really is unlike any other MG going around.
Think of it as like a Lexus to Toyota, or an Audi to Volkswagen, with the Chinese brand going premium, and seemingly making a direct play for Tesla’s fan base. How so? Well, there’s only two models in IM line-up (sound familiar?) with the IM6 a rival for the Model Y, and the IM5 (which we’ve also tested) a competitor to the Model 3.
The IM6 is spacious, pretty sumptuous and ridiculously fast. And it offers up some features I’ve only ever really seen in high-end German metal. But it’s also got some quirks.
So, can MG run with the big dogs of the premium car world with the IM6 Performance? And should Tesla be worried? Let’s find out.
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...

A super solid first outing from the IM brand. Don't let the pricing fool you, there is still bang for buck on offer in the IM6 Performance, even if it at times feels a bit too digital for my tastes.
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.
I feel almost mean saying this, because there will be plenty of people who like the way the IM6 looks, and I don’t want to rain on their parade. But… I’m not one of them.
It reminds me a bit of the pre-facelift Tesla Model Y, in that it’s largely feature-less and a bit blobby, and there’s not a sharp angle anywhere to be found on the thing. Premium to me means powerful and assured — picture just about any Audi — whereas I just find this a bit bland and soft.
Anyway, I do like the big alloys, the insulated glass roof and the light treatment front and rear.
And I like the cabin. The seats aren’t leather, but they’re super thick and comfortable, and there is a genuinely premium air in the cabin, helped by the acreage of screens and the quality elements, like the little door panels.
The doors unlatch electrically, matching the pop-out door handles outside, but they can be a bit fidgety. Someone from MG told me how they worked (you kind of cover the handle and let the door come to you) but I watched everyone else who tried to open them struggle. If you're at the point where you have to explain how a door handle works, you might have over-egged the pudding.
The second screen below the main one acts a bit like a mobile phone. You can alter your home screen widgets and access the main menu, even as Apple CarPlay is synched at the top. You’ll get used to it, I’m sure, but I found it to be a bit fidgety.
Actually it reminds me a little bit of the Lexus trackpad, or whatever that hateful system was called, where you controlled the main screen via a little mousepad thing, though happily it’s nowhere near as annoying as that was.
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.
The IM6 measures 4904mm long, 1988mm wide and 1669mm tall, and it rides on a 2950mm wheelbase, with IM describing it as a "mid-large SUV", though I expect it will be classed as a medium SUV Australia.
That said, ICE and EV mid-size electric SUVs are not cut from the same cloth, with the latter making use of a flat floor to maximise space. And so it is with the IM6, where backseat room is pretty damn impressive. I’m 175cm, and I had no problem at all with legroom or headroom, plus the same plush seats from up there are in the back, too.
There are also air vents but no temperature controls, and while there are USB ports, there is no regular household-style plug in the cabin.
The glass in the windows is laminated, while the roof is double glazed, which MG tells me is Australian summer-proof, but I guess we'll know for sure in a couple of months.
There’s no shortage of cargo room either. There’s a 32-litre frunk up front, and there’s 646 litres in the boot with the rear seats in place. They’re 60/40 split, and if you drop them, luggage space grows to 1621 litres.
The towing capacity is a braked 1500kg, too, but I don’t expect to see many of these towing a camper trailer around.
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.
Premium play means more premium prices, and my IM6 Performance will set you back $80,990 on the road. That might have just sent your eyebrows skyward, but keep in mind it’s faster than some Ferraris, and is swimming with high-end tech, so the bang-for-buck factor is actually still pretty good.
There are cheaper ones, too. The single-motor Premium grade is $60,990 drive-away, albeit with less power and slower charging. Then there’s the Platinum, with a bigger battery and faster charging, which is $69,990
The Performance, though, gets everything IM has to give, including an 800-volt architecture, which means super-fast charging, as well as twin motors, brutal acceleration, a decent driving range and adaptive air suspension.
Elsewhere, you get LED lighting, a big and insulated glass roof, and 20-inch alloy wheels. Inside, there are thick and soft synthetic leather seats that are heated and cooled in both rows, a banging 20-speaker sound system, and wireless charging to pair with wireless Apple CarPlay and Android Auto.
There’s also 'active noise cancellation', and a seat-aware digital assistant which is about the best, and fastest, I’ve ever used. The IM6’s speaker system can locate where a voice is coming from, so any passenger can use the assistant. For example, if you’re in the backseat and say 'hey IM, lower my window', only your window opens. It’s a technology that I specifically remember the German brands crowing about not so long ago.
There’s also a 10.5-inch central touchscreen that controls much of the vast 26.3-inch screen that runs from in front of the driver to the centre of the cabin, as well as clever little magnets embedded in the dash in front of the driver, as well as in the back of the front seat headrests, that are designed to hold phones, iPads or other little accessories.
Also cool is the IM6’s self-parking tech, but there’s also a relatively useless crab walk function, which leans on the rear-wheel steering system to drive diagonally at slow speeds. I’m still not entirely sure when you’d use that one, to be honest.
Honestly, it’s a lot of stuff, and a lot of tech.
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.
This is the real party trick of the IM6, because there’s a nuclear power plant under the metal somewhere. All up, the twin-motor setup produces a total 578kW and 802Nm, though I suspect you’re never accessing all the grunt all at once. Still, 100km/h zips by in 3.4 seconds, and the top speed is 239km/h. For the record, that’s exactly as fast the Ferrari Roma Spider I recently handed back, so yeah, it’s properly supercar quick.
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.
Also on board is a 100kWh Nickel-Cobalt-Magnesium battery that produces a WLTP driving range of 505kms. Pretty good.
Charging is strong, too. The high-tech platform allows for 396kW DC fast charging, which is faster than what is currently offered in Australia. The claim is 30-80 per cent charged in 15 minutes. There’s also an external vehicle-to-load (V2L) port.
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.
First things first, don't get too distracted by the word "performance" here. The IM6 doesn't act like a performance car, it feels bit too plush, and bit too digital, for that.
But that's not necessarily a bad thing. Performance cars are often loud, raucous and uncomfortable, and the IM6 is none of those things. Instead, those mountains of power and torque make silky, silent progress absolutely effortless, which feels pretty premium to me.
MG makes a big deal of how much work went into insulating the cabin from noise – with active noise cancellation joined by double-paned insulated glass – and it is a properly calming and quiet space.
Also strong is the suspension, with the adaptive air setup soaking up most bumps and bruises, but I found it can clang over really solid bumps, sounding like it's bouncing off a stopper. The steering is solid, too, with a nice weight, if not overly talkative in the feedback department, while the rear-wheel steering helps eat into the turning circle for tight three-point turns.
The downside, though, is that it all feels a little too digital, and like there's been a little too much overthinking gone into it. Having to push a button to see behind you in a hurry is bonkers (see my explanation in the Safety section below), and the secondary screen is more annoying than intuitive. And there were several bings or bongs I couldn't even identify. All of which interrupts the otherwise calming nature of the drive experience.
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.
There is a long list of safety aids on the IM6, and I won't detail the lot here. But I will call out a couple of curious mentions.
As always, the driver distraction warning is annoying, but can be switched off. And MG also counts the IM platform, or what it calls a digital chassis, as part of the safety offering. It has its own digital brain that adapts the air suspension, the rear-wheel steering and the active safety kit on the fly.
The other curiosity is the weird way you see out the back. Rather than fit a digital rear-view mirror to counteract the almost non-existent rear vision, you instead push up on a little toggle on the steering wheel to bring up a live view of what's happening behind you on the central screen.
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.
The IM6 is covered by a five-year, unlimited-kilometre warranty, rather than MG’S 10-year term. Capped-price servicing is offered for the first five years, with your total bill just under $3000. The service intervals are 20,000kms or 12 months.
