Mercedes-AMG E63 vs Mercedes-Benz GLB200

What's the difference?

The E 63 S fills its niche in AMG's Australian line-up perfectly. More mature than the brand's four-cylinder hatches and SUVs, but not as overbearing as some of its bigger sedan, GT and SUV stablemates. And its ability to seamlessly switch between serene comfort and dynamic performance has nailed the objective for this 2021 update.

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...

Note: CarsGuide attended this event as a guest of the manufacturer, with travel and meals provided.

The E 63 S has been massaged for 2021 starting with flatter headlights, AMG's now signature 'Panamericana' grille, and a high gloss black flap across the top of the curved 'Jet Wing' section defining the lower part of the nose.

At the same time, the vents on either end of it are larger and feature twin transverse louvers to guide cooling air to wherever it's needed.

It's all about what AMG calls 'optimised aerobalance' but the form is just as appealing as the function. The characteristic 'Power Domes' in the bonnet dial up the muscle, as do the fat wheel arches (+27mm each side), and 20-inch rims with distinctive aero inserts.

This car's optional exterior carbon package consists of a front splitter, side sills, a flash near the fender badges, the exterior mirror covers, the boot lid lip spoiler, as well as the lower apron around the redesigned diffuser and quad tailpipes.

New, intricately styled LED tail-lights are also flatter, but there's even more going on inside.

A new AMG sports steering wheel features three rounded twin-spokes with new switches on the bottom to control the car's dynamic set-up.

It also picks up a new take on the small touch-sensitive controllers used to adjust the instrumentation and manage other functions like phone calls, audio and the cruise control.

Not sure I'm in love with them at this stage. In fact, the words fiddly, imprecise, and frustrating come to mind.

Nappa leather covering the superb AMG sports seats, upper dash, and door beltlines remains standard, but the show-stopper is the 'Widescreen Cockpit' - twin 12.25-inch digital screens for the MBUX multimedia interface on the left and instruments on the right.

The instrument cluster can be set to 'Modern Classic', 'Sport' and 'Supersport' displays, with specific AMG read-outs such as engine data, gear speed indicator, warm-up status, car set-up, as well as a G-meter and 'RaceTimer.'

To borrow an official automotive design term, it looks schmick. Overall, with touches like open-pore black ash wood trim, and brushed metal highlights, the interior looks efficient but classy, with an obvious attention to detail in the layout and its execution.

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.

At just under 5.0m end-to-end the E-Class sits in the upper range of the mid-size luxury spectrum. And almost 3.0m of that is accounted for by the distance between the axles, so there's plenty of space inside.

The driver and front passenger are provided with heaps of room to breathe, and there's a surprising amount of space for those in the back as well.

Sitting behind the driver's seat set for my 183cm (6'0”) position I had more than adequate head and legroom. But access to and from the back is a struggle for full-size adults.

The rear doors open out a long way, but the limiting factor is the size of the aperture, necessitating excessive contortion of the head and limbs to fold in and out of the car.

Connectivity runs to two (power-only) USB-C sockets in the front centre storage bin, as well as another USB-C (for power and multimedia) and 12-volt power outlet in the centre console.

Speaking of the front centre storage bin, it's a decent size and has a padded split lid so it can double as an armrest. There are two cupholders in the front console, a generous glove box, as well as long door compartments with recesses for large bottles provided.

There's a pair of USB-Cs along with another 12-volt socket in the back, sitting under the climate control panel with adjustable vents in the rear of the front centre console. Nice.

The fold down centre armrest incorporates a lidded (and lined) storage box as well as two pop-out cupholders. Again, there are bins in the doors with room for smaller bottles.

The boot offers 540 litres (VDA) of volume, and is able to swallow our three-piece hard suitcase set (124L, 95L, 36L) with room to spare, or the substantial CarsGuide pram, or the largest suitcase and pram combined! There are tie-down hooks to help secure loads, too.

Don't bother looking for a spare of any description, a repair/inflator kit is your only option. And the E 63 S is a no-tow zone.

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.

The E 63 S is powered by the M178 version of the all-alloy 4.0-litre twin-turbo V8 engine used across numerous AMG models from the C-Class up.

Thanks in no small part to direct injection and a pair of twin-scroll turbos (located in the engine's 'hot vee' to optimise throttle response), this all-alloy unit produces 450kW (that's 612hp) from 5750-6500rpm, and 850Nm from 2500-4500rpm.

And as per standard AMG practice for its Vee engines, this car's powerplant was built from scratch by a single engineer in Affalterbach. Thank you Robin Jäger.

AMG calls the nine-speed transmission used in the E 63 S an MCT, which stands for Multi-Clutch Technology. But it's not a dual-clutch, rather a normal auto transmission using a wet clutch as opposed to a conventional torque converter, to connect it to the engine on take-off.

Drive goes to all four wheels via Merc's '4Matic+' AWD system, built around an electromechanically controlled clutch connecting the permanently driven rear axle (with locking diff) variably to the front axle.

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.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 12.3L/100km, the E 63 S emitting 280g/km of CO2 in the process.

That's a pretty hefty number, but in line with this car's proportions and performance potential.

And Merc-AMG has gone to great lengths to minimise fuel use. As well as the standard 'Eco' stop-start function, in the 'Comfort' drive program cylinder deactivation becomes active, the system able to drop four cylinders anywhere between 1000 to 3250rpm.

There's no physical hint of half the cylinders leaving the party. The only clue is a blue icon on the dash indicating a temporary shift to V4 operation.

Despite all that effort, however, we saw a dash-indicated 17.9L/100km over a mix of urban trundling, highway cruising, and some spirited dynamic assessment.

Recommended fuel is 98 RON premium unleaded (although it'll run on 95 at a pinch), and you'll need 80 litres of it to fill the tank. That capacity translates to a range of 650km according to the factory claim, and 447km using our real world result.

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.

AMG's major goal with this upgrade of the E 63 S was to maintain its dynamic response and ferocious performance, but dial in the extra comfort customers had said they wanted.

So, the 4Matic+ AWD system has been fine-tuned for more smoothness as has the Comfort option in the dynamic set-up. But we'll investigate that shortly.

First, that 4.0-litre turbo V8 in the nose is claimed to slingshot this roughly 2.0-tonne sedan from 0-100km/h in just 3.4 seconds, and it feels every bit that fast.

With 850Nm available from 2500-4500rpm and nine gear ratios to help keep you operating in that Goldilocks band, mid-range thrust is monumental. And thanks to the bi-modal sports exhaust it sounds beautifully brutal.

The nine-speed auto's wet clutch, as opposed to a conventional torque converter, is designed to save weight and optimise response. And while some will tell you an auto with one input shaft is never going to be as fast as a dual-clutch with two, shifts are rapid and direct. The wheel-mounted shift paddles are larger and set lower, as well.

The AMG 'Ride Control+' suspension with multi-chamber air suspension and adaptive damping is amazingly good. The underlying set-up is by multi-links front and rear, and despite riding on big 20-inch rims wrapped with low-profile, high-performance Pirelli P Zero rubber (265/35 fr - 295/30 rr) the Comfort setting is incredibly... comfortable.

Slip into 'Sport' or 'Sport+' and the car immediately feels tauter but far less compliant and forgiving. An impression reinforced by the engine, transmission, and steering shifting to a more buttoned-down mode at the same time.

The standard dynamic engine mounts play a big part here. Able to make a soft connection for maximum comfort, but switch to a rigid link when required.

But no matter which mode you're in, the car is well damped and feels beautifully balanced in quick cornering. And the E 63 S's electro-mechanically-assisted variable-rate steering is progressive, feelsome, and accurate.

The 4Matic+ AWD system is built around an electromechanically controlled clutch connecting the permanently driven rear axle (with locking diff) variably to the front axle.

Torque distribution happens imperceptibly, the big V8 putting its power down emphatically, with various electronic systems tieing up the loose ends as you aim up for the next corner.

 There's even a 100 per cent RWD Drift mode available in the Race setting, but without a race circuit at our disposal this time around that'll have to wait for another time.

The optional ceramic brakes feature huge rotors and six-piston front calipers, and stopping power is immense. And the good news is they operate quickly but progressively at normal pottering around town speeds. No warming up required to get them in an optimal temperature zone (as can be the case with other ceramic set-ups).

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.

All AMG models sold in Australia are covered by Mercedes-Benz's five year/unlimited km warranty, with 24-hour roadside and accident assistance included for the duration.

Recommended service interval is 12 months or 20,000km, with pricing for a three-year (pre-paid) plan set at $4300, a $950 saving overall relative to its three year, pay-as-you-go 'Service Solutions' capped price program.

And if you're happy to fork over a little more up-front, there's a four-year service deal at $6300, and five years coming in at $7050.

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.
