Summary
Mercedes-Benz GLB-Class
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.

Mercedes-Benz GLC-Class
Let’s make one thing clear from the very beginning - this new Mercedes-AMG GLC63 S E Performance is technically superior to the model it replaces. Whether it’s actually better or not, is the real question at the heart of the matter.
Why? Because, like the C63 sedan stablemate, AMG has opted to replace the previous model’s 4.0-litre twin-turbo V8 engine with a new 2.0-litre four-cylinder hybrid powertrain. It was a move brought about in part because of increasingly stricter emissions standards in Europe, but also ties-in with the German firm’s success in modern Formula One racing.
While the new hybrid system offers more power, more torque and better fuel economy, as the lukewarm response to the C63 has demonstrated, the hard reality for AMG is that its buyers associate it with V8 and even V12 engines. That emotional pull is hard to replace with logic, even if the new model offers technical superiority.

Verdict
Mercedes-Benz GLB-Class7.8/10
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...

Mercedes-Benz GLC-Class7.7/10
Like I said right from the start, this new, hybrid version of the AMG GLC63 is technically superior to the model it replaces in every meaningful way. It is faster, more powerful and more fuel efficient and therefore a better performance SUV than the model it replaces.
Is it a better model than the one it replaces? Ultimately that will come down to how much stock you put into the soundtrack and your feelings on an AMG not powered by a V8 engine.
Because if you can see past that, then the AMG GLC63 is an absolutely fantastic performance SUV. Not only does the new powertrain make it faster in a straight line, but the chassis is very well-balanced, making for an engaging driving experience.
For those who can look past the smaller engine they will be rewarded with an incredibly fast and rewarding-to-drive member of the AMG family.

Design
Mercedes-Benz GLB-Class8/10
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.
Mercedes-Benz GLC-Class
The GLC63 is unmistakably an AMG from the moment you first lay eyes on it. That’s thanks to the AMG-specific elements, starting with the grille with vertical strikes and the AMG crest on the bonnet; which is now a signature item for the performance sub-brand.
The GLC63 is also fitted with the Night Package II design kit; this adds a darkened grille and black chrome badging to further enhance its visual appeal.
The AMG-specific alloy wheels and more aggressive stance do mean the GLC63 stands out from the rest of the GLC range, helping it look fast even when it’s standing still.
Practicality
Mercedes-Benz GLB-Class9/10
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.
Mercedes-Benz GLC-Class
Inside the GLC63 is clearly a derivative of the rest of the range, with its C-Class-inspired design and layout, but there’s enough AMG-specific elements to ensure it looks and feels special. This starts with the AMG steering wheel, which comes not only with a thick rim wrapped in Alcantara, but also some AMG special dials to adjust the various performance settings for the powertrain, suspension and transmission.
Then there are the AMG-specific seats, which look good and offer good support for the driver and front seat passenger. The rear seats offer decent space for what is a mid-size SUV, with room enough for two adults or teenagers or three smaller kids.
Those in the back aren’t particularly well looked after though, with only rear air-con vents and small door pockets but no USB charging ports or other small item storage.
The boot is 590 litres, down from 620L in the rest of the range, thanks to the addition of the rear-mounted electric motor. There’s also no room for the temporary spare the rest of the GLC range gets and instead you have to make do with a puncture repair kit.
Price and features
Mercedes-Benz GLB-Class7/10
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.
Mercedes-Benz GLC-Class
The power and torque figures aren’t the only numbers that have risen sharply, with the GLC63 clearly impacted by a double whammy of inflation and the usual new-car price rise.
The GLC63 now starts at more than $191,814 for the SUV and $198,415 for the Coupe, which represents a nearly $30k increase over the old V8-powered model, which was priced at $164,600 just two years ago. Even for luxury car buyers that’s a big jump, especially when you’re trying to convince people of the merits of the four-cylinder powertrain.Â
That also means it's more expensive than all of its key competitors, including the BMW X3 M Competition, Maserati’s Grecale and the outgoing, petrol-powered Porsche Macan GTS.
To help explain some of this price increase Mercedes-Benz Australia has opted for a high level of standard specification for local cars. Standard equipment includes 21-inch alloys, AMG composite braking, a panoramic sliding sunroof, a unique AMG steering wheel, power-adjustable sports seats in Nappa leather, a head-up display, dual-zone climate control, wireless smartphone charging and a Burmester 3D Sound system.
Also included is the AMG Track Pace suite, for those who want to unleash their GLC on the racetrack.
There’s also a limited run, AMG Edition 1 Package available too, for an additional $12,900. On the outside you get Manufaktur graphite grey magno paint, foiling with colour gradation and large AMG logo on the sides, an AMG Aerodynamics Package, unique alloy wheels with Edition 1 and AMG branding, yellow brake calipers and an AMG fuel filler cap in silver chrome with AMG lettering.Â
Inside there’s AMG Performance seats, AMG Nappa leather in black with yellow contrasting stitching, AMG illuminated door sills, carbon-fibre AMG trim highlights, yellow seat belts and a unique AMG Performance steering wheel wrapped in carbon-fibre and microfibre.
Under the bonnet
Mercedes-Benz GLB-Class8/10
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.
Mercedes-Benz GLC-Class
This is what lies at the heart of the AMG GLC63’s success or failure. As I mentioned at the beginning, the previous generation’s 4.0-litre twin-turbo V8 has been replaced by an F1-inspired plug-in hybrid powertrain.
But don’t think that means AMG is suddenly focused on efficiency over performance. When AMG says the powertrain is inspired by the brand’s success in Formula 1 racing, what it means is the battery and electric motor provides a significant performance boost to support the internal combustion engine, not just save fuel.
To that end the combination of the turbocharged 2.0-litre four-cylinder petrol engine and the rear-mounted electric motor produces an impressive 500kW and 1020Nm. That’s a massive jump over the 375kW/700Nm made by the outgoing V8.
Efficiency
Mercedes-Benz GLB-Class8/10
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.
Mercedes-Benz GLC-Class
Mercedes makes no secret that the battery is designed for performance, not saving fuel. It only has a 14km EV range but can recharge quickly on the move to provide a power boost when needed.
But despite all that, the GLC63 is actually significantly more fuel efficient than the old V8, using a claimed 7.3L/100km, which is a massive 4.9L/100km improvement over the old model. Although, on our day-long test drive we didn’t manage to come close to that claimed figure and instead saw returns around 11L/100km, albeit after a lot of spirited open-road driving.
Driving
Mercedes-Benz GLB-Class8/10
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.
Mercedes-Benz GLC-Class
Anyone who still believes in the adage ‘there’s no replacement for displacement’ hasn’t driven a modern turbocharged and hybridised engine. The GLC63 is a demonstration of the metaphorical and literal power of modern technology, combining an extremely efficient and potent internal combustion engine with an electric motor to make enormous real-world performance.
To be blunt, the GLC63 feels like a rocketship out of corners, launching with a ferocity and relentlessness the old V8 simply can’t match. It shouldn’t come as a surprise, a mid-size SUV with 1020Nm was always going to have plenty of performance, but even so it’s a shock to the system every time you give the GLC63 full throttle. Officially AMG claims it takes just 3.5 seconds to run 0-100km/h and has an electronically limited top speed of 275km/h - mighty impressive figures for a five-seat mid-size SUV.
To help get all that torque to the road, AMG deploys torque distribution technology that allows for it to be split an even 50/50 front/rear all the way to 100 per cent to the rear tyres.
Other technologies deployed to enhance its handling include AMG Ride Control suspension with adaptive damping and rear-axle steering. There’s also eight AMG Dynamic Select driving modes and four AMG Dynamics settings (Basic, Advanced, Pro and Master), so it’s a complex vehicle that is designed for the enthusiast.
While it’s easy to drive around town, once you get out on the open road you can really get a sense of the GLC63’s performance potential. Beyond just its powertrain the suspension offers good body control and the rear-axle steering helps it feel agile and responsive.Â
It’s not perfect though. At times the complexity of the system does lead to some hesitation when you put your foot down. It certainly lacks the linear power delivery of the old V8 and makes for a slightly trickier driving experience at times.
As for the sound, which is one of the biggest elements missing from the V8, Mercedes has added AMG Real Performance Sound, which features a pressure sensor in the exhaust that picks up on the engine note and plays it through the speaker system. It certainly helps make for a louder, more noticeable engine noise, but it still sounds more like an A45 than the previous GLC63 and for many would-be buyers, that’s a major turn-off.
Safety
Mercedes-Benz GLB-Class7/10
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.
Mercedes-Benz GLC-Class
The GLC63 comes standard with a comprehensive suite of safety features including 'Distronic' (Mercedes’ name for adaptive cruise control), 'Active Lane Keeping Assist', 'Blind Spot Assist', 'Traffic Light Assist' and 'Adaptive Highbeam Assist'. It also includes Mercedes’ 'Pre-Safe' accident anticipation system - which pre-tensions the seat belts and will even play a white noise to protect your ears if it senses a crash is imminent.
A parking system that includes a 360-degree camera and active parking assist is also included.
The GLC range was awarded a five-star ANCAP rating in 2022, which pre-dates the latest testing protocols, so doesn’t provide a like-to-like comparison for vehicles tested after that date.
Ownership
Mercedes-Benz GLB-Class7/10
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.
Mercedes-Benz GLC-Class
The GLC63 is covered by Mercedes Australia’s usual five-year/unlimited kilometres warranty.
As for maintenance, Mercedes offers service plans, spanning three to five years. Three years will cost you $5025, $6455 for four years and five years is priced from $7180. Servicing intervals are 12 months or 20,000km, whichever comes first.
