What's the difference?
When the GLB arrived in Australia in 2020 it did so to much fanfare as the little premium SUV which could do it all.
It had seven-seats, ideal dimensions slotting underneath the mid-size GLC, the option of all-wheel drive, and even a go-fast AMG version to boot.
Now, the clever little luxury SUV can add another headline feature - it’s gone fully electric.
The EQB, like the EQA before it, follows the formula of its donor car to a T, being familiar for an existing Mercedes buyer whilst also making the jump to a fully electric drivetrain.
For now it comes in two variants, a two-wheel drive with seven seats, and a five-seat all-wheel drive which leans more on the performance aspect of its electric drivetrain. Is the trade-off worth it?
The answer is: It depends. Read on to find out why.
The SUV craze is such that high-riding wagons are increasingly being tasked with also doing the job of sports cars, despite the immutable laws of physics clearly working against them.
While the results have been mixed, Mercedes-AMG has some serious form in this area, so much so that it’s been confident enough to unleash the second-generation GLE63 S.
Yep, this large SUV is looking to do its best impersonation of a sports car, so we’re looking to find out if it’s a convincing Jekyll and Hyde. Read on.
I really liked the combustion version of this car, the GLB, for its funky style and flexibility and I was pleased to find how easily Mercedes has made the conversion to a fully-electric layout for the EQB.
Despite a tall price, the EQB 350 is a compelling option for those seeking something a bit more luxurious than the Tesla Model Y, something a bit larger than the Volvo XC40 Recharge, and something a bit smaller than the Audi e-tron or the EQC.
The main trade-off for this 350 variant is the loss of the seven-seat layout in favour of more performance. Instead it offers a huge boot, has a sufficient range for city-based buyers, and offers surprising levels of fun, too.
Just make sure you’ve considered its rivals which may potentially offer more range or features for the same money.
There’s little wonder the GLE63 S is back for a second go around, after clearly putting the frighteners on the Audi RS Q8 and BMW’s X5 M Competition and X6 M Competition.
After all, it’s a large SUV that sacrifices little in the way of practicality (especially the wagon) in its pursuit of high performance.
And for that reason, we’re itching to go for another drive – with or without the family.
Note: CarsGuide attended this event as a guest of the manufacturer, with travel and meals provided.
The EQB has a very predictable design in that it doesn't stray from the combustion car’s formula. At all.
The only evidence from the outside this is the electric version is the blanked out grille, and closer observers might notice the rear light bar which cuts across the boot lid is different from the split tail-light design which appears on the combustion car.
Still, to my eyes, the GLB is a cool design with its upright boxy look bucking the curvaceous trend of most EVs, and, indeed, the rest of the Mercedes line-up.
Its rebellious streak makes it one of the most appealing SUVs in Mercedes’ current range, and it comes with a bit of toughness which is missing from the EQA.
If nothing else, it’s a completely different look from Tesla’s amorphous Model Y, and this may be enough to appeal to some.
Inside is identical to other Mercedes models which sit on the MFA2 small car platform, immediately setting itself apart with the big high-resolution screens, glitzy ambient lighting, as well as an abundance of chrome and gloss black.
It’s designed to impress from the first time you hop in, and there’s no doubt it does, but it may be a bit over-the-top for some, particularly fans of the more conservative Mercedes designs of eras past.
The chrome in particular becomes a bit of a problem, as it has an annoying habit of catching the reflection of the sun and sending it directly into the driver’s eyes.
It all feels as plush as a circa-$100,000 luxury car should though, with the ‘Artico’ seat trim being one of the better synthetic options on the market, and soft-touch surfaces throughout the cabin selling the Mercedes promise.
The GLB toughness is even reflected in the chiselled out finishes in the door, dash, and centre console, helping to set it apart from the tamer EQA.
The software is also fast, high resolution, and well presented, which bodes well given the amount of screen real-estate, and the amount of customization is impressive, too.
Again, there are many who will prefer its look and feel to the Apple-store chic of the Tesla Model Y, or the pared back Scandinavian approach of the XC40 Recharge, but also those who won’t. Like many new Mercedes products, it continues to polarise buyers.
First things first, the new GLE63 S is available in two body-styles, with the wagon appealing to the traditionalists out there, while the coupe targets the style-conscious.
Either way, few large SUVs are as imposing as the GLE63 S, which is a good thing considering it wants to be taken seriously.
Up front, it’s immediately identifiable as a Mercedes-AMG model thanks to its distinctive Panamericana grille insert.
The angry look is punctuated by the angular daytime running lights integrated into the Multibeam LED headlights, while the chunky front bumper has large air intakes.
Around the side, the GLE63 S stands out with its aggressive wheelarch extensions and side skirts, with the wagon getting 21-inch alloy wheels as standard, while the coupe gets 22-inch items.
From the A-pillars onwards, the differences between the wagon and coupe body-styles start to become apparent, with the latter’s roofline much more steeply raked.
At the rear, the wagon and coupe differentiate themselves even more clearly with their unique tailgates, LED tail-lights and diffusers. That said, they do have a sports exhaust system with squared-off quad tailpipes in common.
It’s worth mentioning that the difference in body-style also means a difference in dimensions, with the coupe 7mm longer (4961mm) than the wagon, despite having a 60mm-shorter wheelbase (2935mm). It’s also 1mm narrower (2014mm) and 66mm shorter (1716mm).
Inside, the GLE63 S separates itself with its flat-bottom steering wheel with Dinamica microfibre accents, and multi-contour front seats, which are upholstered in Nappa leather alongside the armrests, dashboard and door shoulders and inserts.
The door bins are of the hard plastic variety. That’s underwhelming in a vehicle that costs this much, as you would hope cow hide – or at least a soft-touch material – would be applied to them.
The black headliner acts as another reminder of its performance focus, and while it makes for a darker cabin, metallic accents feature throughout, while the trim (our test vehicle had open-pore wood) adds some variety alongside the ambient lighting.
That said, the GLE63 S is still filled to the brim with cutting-edge technology, including two 12.3-inch displays, with one the central touchscreen and the other a digital instrument cluster.
Both use Mercedes’ MBUX multimedia system and feature Apple CarPlay and Android Auto support. This set-up is still the benchmark, thanks to its speed and breadth of functionality and input methods, including always-on voice control and a touchpad.
This should be the GLB’s calling card. It’s a car with an ideal footprint, not as wide or as long as most mid-size SUVs, whilst also offering a larger cabin and boot.
The big drawback for this variant in particular is the lack of a seven-seat option, as the all-wheel drive requires the under-floor space which is required to give rear occupants legroom.
It’s a shame, too, because I found the two rear seats in this car’s GLB combustion equivalent to be surprisingly accommodating for even adults.
As a result of these missing seats, though, the full volume can be exploited in the boot, which comes in at a whopping 495 litres.
It’s rivalled by the Model Y, which also has a cavernous boot, although it has a much larger storage area than the Volvo XC40.
As an added bonus, there is a decent under-floor storage area which has enough space for all your charging cables, although there is no so-called ‘frunk’ with what is normally the engine bay taken up by cooling and auxiliary hardware.
At first glance there’s so much going on under there, you’d be forgiven for thinking the EQB has an actual engine!
The cabin is also enormous as well as configurable. The EQB has massive rear doors (as it’s designed to be a seven-seater) to make it easy to get in and out of, and once you’re settled in, the amount of space for me (at 182cm) behind my own driving position is very impressive, with ample leg, arm, and headroom.
Rear passengers score the same nice synthetic leather seat and door trim as the front passengers, a bottle holder in each door, as well as two in a flip-out caddy on the drop-down armrest, two nets on the backs of the front seats, dual adjustable air vents, and power outlets on the back of the console. There is also a separate section of the split sunroof to benefit those in the back seat.
Up front the cabin is equally flexible, although it immediately seems odd that the front seats are manually adjustable. Almost unforgivable in a $100,000 car.
At least the trim is comfortable, and again, the space is configurable for people of all shapes and sizes.
Storage options include large bins in each door, a split-opening armrest console with USB-C outlets inside, a slide-open area underneath the climate unit, which houses a wireless phone charger and additional power outlets, as well as the usual glove box arrangement.
Soft trims continue into the doors, although one small annoyance is the excess of chrome trim which has the unfortunate habit of reflecting harsh Australian sun into your eyes if it hits at the wrong angle.
The software is nice and quick, but can be cumbersome and over-complicated to operate at times, particularly when using the centre touchpad, or adjusting the dash with the small touch elements on the wheel.
It is also notable the Apple CarPlay as-tested only took up a centre portion of the screen, and is not set-up for widescreen mode to take full advantage of the hardware.
Minor complaints aside, though, the EQB follows its combustion GLB twin in having by far one of the most flexible and configurable cabins in its class.
Being a large SUV, you’d expect the GLE63 S to be quite practical, and it is, but what you wouldn’t expect is the coupe to have 25L more cargo capacity than the wagon, at a generous 655L, due to its higher window line.
That said, when you stow the 40/20/40 split-fold rear bench via the second row’s release latches, the wagon has a significant 220L advantage over the coupe, at a cavernous 2010L, thanks to its boxier design.
Either way, there’s a small load lip to contend with, making loading bulkier items a little more difficult, although that task can be made easier with the flick of a switch, as the air springs are able to lower the load height by a handy 50mm.
Better yet, four tie-down points are on hand to help secure loose items, alongside a couple of bag hooks, while a space-saver spare resides under the flat floor.
In the second row, things are even better, with the wagon offering a crazy amount of legroom behind our 184cm driving position, as well as two inches of headroom for me.
With its 60mm-shorter wheelbase, the coupe naturally sacrifices some legroom, but it still provides three inches of legroom, while its sloping roofline trims headroom to an inch.
No matter the body-style, the five-seat GLE63 S is wide enough to seat three adults abreast with few complaints, with the transmission tunnel on the smaller side, meaning there’s plenty of room for feet.
There’s also plenty of room for child seats, with two ISOFIX and three top-tether anchorage points on hand for fitting them.
Amenities-wise, rear occupants are treated to map pockets on the front-seat backrests, as well as a fold-down armrest with two cupholders, while the door bins can accommodate a couple of regular bottles each.
A fold-out cubby is positioned below the air vents at the rear of the centre console, containing two slots for smartphones as well as a pair of USB-C ports.
In the first row, occupants have access to the centre console’s cubby, which features two temperature-controlled cupholders, in front of which are a wireless smartphone charger, two USB-C ports and a 12V power outlet.
The central storage bin is pleasingly large and contains another USB-C port, while the glovebox is also on the larger side, and you get an overhead sunglasses holder too. Stunningly, the front door bins can take three regular bottles apiece. Not bad.
While the wagon has a large, square rear window, the coupe’s is a letterbox in comparison, so rearward visibility isn’t one of its strong suits.
The EQB range kicks off from $87,800, before on-road costs, for the base 250, but the car we’re looking at for this review is the top-spec 350 4Matic, which wears a price-tag of $106,700.
There’s no doubt it’s a hefty price, even for an EV, and especially for a sort-of ‘small’ SUV. There’s more to consider, too. As I mentioned in the intro, the all-wheel drive system precludes the seven-seat layout in this top-spec car, and it has less range than the front-wheel drive model, too, dropping from 371km to 360km.
On the upswing, the dual-motor powertrain is far preferable to the so-so front-wheel drive option, and the 350 also gains an AMG-spiced bodykit and flat-bottomed steering wheel, as well as a panoramic sunroof.
Outside of the extra flair, the EQB 350 is almost as well equipped as you could hope, with the flashy dual-10.25-inch 'MBUX' screen set-up, Nappa leather steering wheel and interior appointments with Mercedes’ signature 'Artico' synthetic seat trim, LED headlights, ambient interior lighting with fully customisable RGB controls, dual-zone climate, a wireless phone charger, 20-inch alloy wheels, as well as keyless entry and push-start ignition.
Given the EQB’s dimensions it would seem its most direct rival is the Tesla Model Y, although it may not be a favourable comparison.
At over $100,000 the EQB 350 is still more expensive than the top-spec Model Y Performance, which is even more powerful than our Merc here.
Other more indirect rivals include the Volvo XC40 Recharge (from $74,490 in twin-motor form), or less performance-oriented Lexus UX300e ($80,691 for the top-spec Sports Luxury), although neither are as large as the EQB, and the Lexus has about half the performance.
Priced from $220,600 plus on-road costs, the new GLE63 S wagon is $24,571 dearer than its predecessor. While the rise is unfortunate, it is accompanied by the fitment of a lot more standard equipment.
And the same is true of the new GLE63 S coupe, which is priced from $225,500, making it $22,030 more expensive than its forebear.
Standard equipment for both cars includes metallic paintwork, dusk-sensing lights, rain-sensing wipers, power-folding side mirrors with heating, side steps, soft-close doors, roof rails (wagon only), keyless entry, rear privacy glass and a power-operated tailgate.
Inside you score push-button start, a panoramic sunroof, satellite navigation with live traffic, digital radio, a 590W Burmester surround-sound system with 13 speakers, a head-up display, a power-adjustable steering column, power-adjustable front seats with heating, cooling and massaging functionality, heated front armrests and outboard rear seats, four-zone climate control, stainless-steel pedals and an auto-dimming rearview-mirror feature.
Rivals for the GLE63 S include the less expensive Audi RS Q8 ($208,500) and BMW’s X5 M Competition ($212,900) and X6 M Competition ($218,900).
While the EQB 350 loses its valuable third-row seats, it gains a much more impressive drivetrain than the lesser EQB 250 variant.
While that car has a so-so front-motor set-up producing 140kW/385Nm, the top-spec 350 sports a much more capable 215kW/520Nm dual-motor system.
This allows a 0-100km/h sprint time of 6.2 seconds, and while it’s not as fast as the entry-level Tesla Model 3, it’s still impressive for a 2153kg SUV.
The all-wheel drive capability also adds a level of confidence which can’t be matched by a front-drive, more on this in the driving section of this review.
The GLE63 S is powered by Mercedes-AMG’s ubiquitous 4.0-litre twin-turbo V8 petrol engine, with this version pumping out a hard-hitting 450kW of power at 5750rpm and 850Nm of torque from 2250-5000rpm.
But that’s not all, because the GLE63 S also has a 48V mild-hybrid system called EQ Boost.
As its name suggests, it has an integrated starter-generator (ISG) that can provide up to 16kW and 250Nm of electric boost in short bursts, which means it can also reduce the sensation of turbo lag.
Mated to a nine-speed torque-converter automatic transmission with paddle-shifters, and Mercedes-AMG’s fully variable 4Matic+ all-wheel-drive system, the GLE63 S sprints from a standstill to 100km/h in just 3.8 seconds, in either body-style.
Regardless of which version of the EQB is chosen, the SUV has a 66.5kWh lithium-ion battery pack, and in the case of our all-wheel drive 350, this grants it a 360km WLTP-rated driving range between charges.
My car was reporting around 350km of range at or near a full charge, while my week of testing produced a dash-reported consumption figure of just 18.2kWh/100km.
This is surprising for two reasons. Firstly, I subjected the EQB 350 to a significant amount of freeway testing during my time with it, which usually produces worse consumption numbers for EVs, but it actually bested its official 21.0kWh/100km official figure by a decent margin.
Secondly, I’m puzzled to find this car outperformed the smaller and lighter EQA 250 I had on test in 2021 in terms of overall consumption, and by a significant margin. Very odd.
When it comes to charging up, the EQB can be charged at a rate of 100kW on a fast DC charger, for a 10-80 per cent charge time in a claimed 30 minutes.
On the slower but cheaper-to-install AC standard, the EQB has an 11kW inverter, allowing a convenient ‘slow’ charge time of 4.1 hours. Expect between 25 and 30 hours on a standard wall socket.
The GLE63 S’s fuel consumption on the combined-cycle test (ADR 81/02) varies, with the wagon achieving 12.4L/100km, while the coupe needs 0.2L more. Carbon dioxide (CO2) emissions are 282g/km and 286g/km respectively.
When you consider the high level of performance on offer, all of these claims are fairly reasonable. And they’re made possible by the engine’s cylinder-deactivation technology and the 48V EQ Boost mild-hybrid system, which has coasting and extended idle-stop functionality.
That said, in our real-world testing with the wagon, we averaged 12.7L/100km over 149km. While that’s a surprisingly good result, its launch drive route mainly consisted of high-speed roads, so expect a much higher number in metropolitan areas.
And in the coupe, we averaged a higher but still respectable 14.4L/100km over 68km, although its launch route purely involved high-speed country roads, and you know what that means.
For reference, the wagon has an 80L fuel tank, while the coupe has an 85L unit. Either way, the GLE63 S only takes more expensive 98RON premium petrol.
This is where the 350 version of the EQB shines. This car is a beast to drive with plenty of power available at your right foot, and incredible amounts of traction to match from its torque-vectored all-wheel drive system.
This lets it be rapid, but not scary, and despite its square and upright body, might surprise you when it comes to carving a few corners.
Like many EVs, the EQB’s weight feels low and centred, but it appears the suspension has been adjusted to remove any bouncy quality, which might come with the additional weight added over the combustion variants, with nearly 500kg of lithium batteries under the floor.
In fact, the ride is also one of the things which impressed me most about the EQB. It even has huge 20-inch AMG wheels, yet it dealt with bumps of all shapes and sizes in an impressive manner, keeping the body under control, and communicating remarkably little in terms of vibration or unpleasantness into the cabin.
The steering offes a nice balance of feel and electrical assistance, a trait which combines with the EQB’s convenient size to make for an easy SUV to park and manoeuvre.
When it comes to the EQB’s traits as an electric car, there are several modes available to alter the experience.
Using the paddle shifters, there are several regenerative braking settings to choose from. While none of them are a ‘single pedal’ mode, the D- mode is pretty strong, and clearly contributed to the EQB’s surprisingly good energy consumption in my time with the car.
Activating D+ mode, which can be combined with a sporty driving setting, tones down the regenerative setting almost completely and feels as though it unleashes more potential from the potent electric motors.
While the sportier settings made the 2WD EQA I tested last year feel a little twitchy and prone to wheelspin, the all-wheel drive system keeps this well under control in the larger EQB for impressive acceleration characteristics.
The breadth of this SUV’s ability is perhaps its most impressive attribute. It can feel comfortable and tame around town, with alarming speed and tenacity when attacking the open road should you so desire.
Sure, it’s not as whiplash-inducing as some of its rivals, particularly the Volvo XC40 Recharge or Tesla Model Y, but for a luxury SUV like this it’s more than what you could ask for.
Make no mistake, the GLE63 S is a big beast, but it certainly doesn’t act its size.
Firstly, the GLE63 S’s engine is an absolute monster, helping it to hunker down off the line and then charge on towards the horizon with serious vigour.
While there’s so much initial torque to begin with, you still get the added benefit of the ISG, which helps to eliminate lag as the new twin-scroll turbos spool up.
That said, acceleration isn’t always brutal, as the electronic stability control (ESC) is often quick to cut power when under full throttle in first gear. Thankfully, engaging the ESC system’s Sport mode solves this issue.
This behaviour is somewhat ironic as the 4Matic+ system is seemingly never short of grip, with it's working hard to find the axle with the most traction, while torque vectoring and a rear limited-slip differential proportion torque from wheel to wheel.
Regardless, the transmission provides predictably smooth and predominantly timely gear changes, although they’re definitely not dual-clutch quick.
What’s more memorable, though, is the sports exhaust system, which keeps your neighbours relatively sane in the Comfort and Sport drive modes, but will drive them mad in Sport+, with hilarious crackles and pops heard loud and clear on the overrun.
It’s worth noting that while the sports exhaust system can be manually engaged in the Comfort and Sport drive modes via a switch on the centre console, it only makes the V8 rumble grow stronger, with the full effect only unlocked in Sport+.
Of course, there’s more to the GLE63 S experience, like the fact that it somehow rides like a large SUV yet handles like a sports car.
The suspension’s air springs and adaptive dampers offer up a luxurious ride in the Comfort drive mode, with the GLE63 S wafting along with confidence. Not even its large-diameter alloy wheels pose too much of a threat to this quality on poorer country roads.
The ride is still more than liveable in the Sport drive mode, although the adaptive dampers become a too firm in Sport+, with the ride becoming a little too jittery to be bearable.
Of course, the whole point of the adaptive dampers becoming progressively firmer is to help the GLE63 S handle even better, but the real revelations here are the active anti-roll bars and engine mounts, which effectively limit body roll to such a level that it’s almost imperceptible.
In fact, overall body control is impressive, with the GLE63 S not feeling like the 2.5-tonne-plus behemoth it is. It really has no right to attack corners the way it does, with the coupe feeling a touch tighter than the wagon, thanks to its 60mm-shorter wheelbase.
Further confidence is afforded by the sports brakes, which include 400mm discs with six-piston calipers up front. Yep, they wash away speed with ease, which is exactly what you’d hope for.
Also key to the handling is the electric power steering, which is speed-sensitive and has a variable ratio. It’s really quick in the wagon, and even more so in the coupe, thanks to its more direct tune.
Either way, this set-up is well-weighted in the Comfort drive mode, with plenty of feel and just the right amount of heft. That said, Sport and Sport+ make it gradually heavier, but neither make the driving experience better, so stick with the default setting.
Meanwhile, Noise, Vibration and Harshness (NVH) levels are pretty good, although tyre roar is consistent at highway speeds, while wind whistle is prominent over the side mirrors when travelling above 110km/h.
The EQB scores a thorough suite of active safety equipment including freeway-speed auto emergency braking (7.0-200km/h), lane keep assist with lane departure warning, blind-spot monitoring with rear cross-traffic alert, as well as one of the best adaptive cruise systems on the market.
In the event of an impact, the EQB scores dual front, side, and head curtain airbags (the side and curtain bags cover both rows) as well as a driver’s knee airbag. There are the usual dual outboard ISOFIX child seat mounting points on the rear row, as well as three top-tether points.
The EQB scored a maximum five-star ANCAP safety rating to the current 2022 standards, but this rating only covers the base 250 variant. It scored highly across all criteria.
ANCAP awarded the second-generation GLE range its maximum five-star rating in 2019, meaning the new GLE63 S gets full marks from the independent safety authority.
Advanced driver-assist systems generously extend to autonomous emergency braking with pedestrian and cyclist detection, lane-keep and steering assist (including emergency), adaptive cruise control with stop and go functionality, traffic-sign recognition, driver attention alert, high-beam assist, active blind-spot monitoring and cross-traffic alert, tyre pressure monitoring, hill-descent control, park assist, surround-view cameras and front and rear parking sensors.
Other standard safety equipment includes nine airbags, anti-skid brakes, electronic brake-force distribution and the usual electronic traction and stability control systems.
Mercedes offers a five year and unlimited kilometre warranty, with five years of roadside assist. The high-voltage battery components are also covered by a separate and industry-standard eight-year and 160,000km warranty.
Service intervals are once every 12 months or 25,000km and the service plan costs an average of $440 a year for the life of the warranty which is expensive for an EV, especially considering Polestar offers free servicing for the first five years, and Volvo’s electric offerings are around half the cost over the same period.
As with all Mercedes-AMG models, the GLE63 S comes with a five-year/unlimited-kilometre warranty, which currently sets the standard for the premium market. It also comes with five years of roadside assistance.
Better yet, the GLE63 S’s service intervals are relatively long, at every year or 20,000km – whichever comes first.
It’s also available with a five-year/100,000km capped-price-servicing plan, but it costs $4450 in total, or an average of $890 per visit. Yep, the GLE63 S isn’t exactly cheap to maintain, but you expected that.
