Mercedes-Benz EQ-Class vs Mercedes-Benz EQB

What's the difference?

When I was telling my colleagues about the Mercedes-Benz EQC my summary was, basically, it’s the best electric luxury car I’ve driven. 

It’s plusher than a Jaguar i-Pace, more polished than a Tesla Model X - indeed, it feels like a different kind of electric car to both of those models. It’s an impressive foray into the segment, and we can’t wait for the chance to put it against some like-minded electric European luxury SUVs at some point in the future.

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.

The Mercedes-Benz EQC is entirely different to what we expect from the brand, but it’s really what we expected all along when it came to an electric SUV from the Daimler stable.

It is sleek, streamlined and smooth, with panels that almost look like they’re formed from liquid. And it has the eco-edgy graphics you’d expect, with a specific grille treatment (yes, a real grille), headlights that are unlike any other Benz (they even have an LED that runs the width of the grille), and a rear-end style that looks almost like it was penned with another Stuttgart-based brand in mind… Porsche. I’m talking about Porsche.

But one thing that I really love about the EQC is its moustache. It's more prominent when the car is finished in white paint, but there’s a moustache that former Daimler chief Dieter Zetsche himself could be envious of. And he had one helluva soup strainer.

It is clearly made to be slippery, despite essentially sharing its underpinnings with the more conventionally angular - yet still rounded-edged - GLC SUV.

While it is a nicely styled gizmo, I found there are some things that could be annoying.

For instance, I was trying to plug in at night in a dark area, and while there is a small light above the charge port, other EVs have a light that actually illuminates the area where you’re plugging in. 

And also, the plug port is on the driver’s side. If, like me, you had to charge up with the car on the street, it just adds a little bit more anxiety to the whole situation. I shudder to think what could happen if the charger was hit by a passing car - folding the mirrors in is one thing, but you can’t fold the power cable! The lead for the charger is long, thankfully. 

I know, most people (maybe even all people!) who buy and EQC are going to have undercover parking in a garage or carport, but it’s still worth remembering that the filler isn’t on the kerb side like a number of other EVs. 

It has almost identical dimensions to that car: 4774mm long on a 2873mm wheelbase, with a width of 1884mm and a height of 1622mm. For context, GLC is 4669mm long, same wheelbase, a bit wider (1890mm) and just a little more height (1639mm).

What about interior design? Well it’s also familiarly different, with a number of changes to the materials used but still the same tech and comfort you’d expect. Check out the interior images in the section below.

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.

If you’re thinking the EQC looks like a seven-seat SUV, you’re wrong. It’s a five-seater, with a decent sized boot, too.

The luggage capacity is 500 litres, which is decent for a car of this size, but bear in mind there is no spare wheel under the boot floor. 

Rear seat space is reasonably spacious for someone my size (182cm) sitting behind their own driving position, with decent knee and toe space. Headroom is not terrific, though, and anyone taller will need to watch their head as they get in and out of the car as the top sill eats into space quite a bit. 

Any middle-seat passengers might find the room a little less likeable, as the transmission tunnel intrudes quite a bit. Those with big feet might find shoehorning themselves in and out a bit of a challenge as the sills are quite large, and our car even had optional ($1200) “aluminium-look running boards with rubber studs” - side steps, essentially. They get in the way, too.

But if you’re just sitting two abreast in the back the seat comfort is really good, the trim quality is excellent, and there is a flip down armrest with the storage bin and pop out cupholders. There are rear air vents (no climate control adjustment in the back, though, and no USB charging either), and there are two map pockets, plus bottle holders in the doors. Up front you will find a mix of familiar elements if you’ve sat in any recent Benz model, but a few unique finishes and trim elements that might be new to you.

There’s a beautiful horizontal fin theme that runs around the cabin, as well as the now-traditionally audacious looking Burmester sound system speaker covers. They don’t quite gel with the aesthetic, to my eye. 

The dash-top material - “fine surface texture”, as Benz calls it - is unlike anything else we’ve seen from the brand, it’s kind of like a soft silky slippery fabric trim. While there are lovely copper trim elements that just add something visually entertaining and appealing to the space.

There is a large covered centre console bin with 2x USB-C charge points and there is an additional USB-C upfront next to the wireless phone charger. The Mercedes touchpad system that aligns with the MBUX media screen is reasonably easy to get used to, but being a Benz there are plenty of options for usability - the centre screen is a touch-capacitive unit, or you can use the steering wheel-mounted controller on the left side of the wheel to control the middle screen. The right thumb controller manages the driver info screen.

It was mostly very easily managed, although the menus did get stuck at times for me - mainly in the section around the energy consumption. Plus I tried the whole “Hey, Mercedes” command thing, and it failed on numerous occasions. 

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.

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.

The EQC has a power output of 300kW and it has 760Nm of torque, which is enough to see its claimed 0-100km/h acceleration pegged at just 5.1 seconds.

The EQC’s top speed is 180km/h (limited for the sake of the batteries), and it has an 80kWh lithium-ion battery pack.

It uses a pair of asynchronous motors - one front, one rear - and they can alternate to do what’s best in the situation - be it working in 2WD (RWD or FWD), or in AWD. 

If you’re thinking about an EQC as a towing option, the towing capacity is 750kg for an un-braked trailer and 1800kg for a braked trailer.

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.

With an 80kWh battery pack and a Type 2 CCS plug (up to AC 7.4kW / DC 110kW) the charge times vary pretty greatly depending on what output you’re powering up from.

Mercedes-Benz says a DC fast charging station should be able to replenish the battery bank in 1 hour 22 minutes (at a maximum of 110kW, though some Chargefox stations offer charge rates up to 350kW) while an AC charging station (like you’d find in car parks) or Mercedes-Benz’s own Wallbox system should take about 12 hours 13 minutes.

Charging from a regular household powerpoint is a last resort option. It is claimed to take 46 hours 40 minutes from empty to full (230-volt outlet, 10-amp/2.3kW). I plugged in to a powerpoint in my house and the car’s info display was stating it would take 9.5 hours to achieve the remaining 16 per cent of charge. It didn’t get to 100 per cent before I had to unplug, however.

My not-so-urban test drive loop commenced with 97 per cent of battery charge and an indicated range of 363km available. The idea was to get a feel for the “range vs reality” of the situation, so I did it in Comfort drive mode with the climate control active and no intent to either thrash the vehicle or baby it to save battery.

My drive ended with 36 per cent indicated charge remaining, after I’d covered 231.6km. That means, based on the car’s own algorithm, that it would have covered 315km before the battery was depleted, which is a long way short of the claimed 434km range.

The indicated energy consumption was 20.8kWh/100km, which is ‘thirsty’ for an EV. On our recent electric car comparison test, the most efficient of our EVs - the Hyundai Ioniq Electric - used just 13.0kWh/100km. Yes, I know the EQC is a lot heavier (2425kg kerb weight), but even the Tesla Model 3 was notably more efficient (18.5kWh/100km) than the EQC over very similar terrain and driving.

However, our testing saw us return an even better consumption rate than Mercedes-Benz’s claimed figure, which is 21.4kWh/100km.

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.

If you have a garage and a Wallbox connector, there’s no reason the Mercedes EQC couldn’t be a terrific option as a commuter, a second car, or even your primary vehicle. 

The thing with all electric cars is that it’s about settling into a rhythm. If you use the car to commute to work, maybe you can charge it there. Or you might have a solar array and charge at home.

No matter the situation, you’ll be getting a rather nice vehicle to live with, based on my week with the EQC.

It’s a plush car, that’s for sure. The silence it offers is truly relaxing, and there’s effortless torque to pull you away from a standstill. The way you can build pace to overtake, the rush of noise-free acceleration, is pretty astounding. Perhaps not as visceral as in a GLC 63 AMG, but it’s still an experience.

The steering is direct and doesn’t require much thought, though it does lack a little bit of feel. But it’s easy to predict and quick to respond, making for pleasant progress around town. It’s easy to park, as well, with a great surround view camera system, as well as front and rear parking sensors. And if you’re not confident, the car has semi-autonomous parking, too.

The brake pedal feel takes some acclimation, because it responds pretty well, but the action is hard to modulate at times. That is partly due to the brake regeneration system, which actively captures energy that would have otherwise been lost during braking. You can adjust the level of aggression of the regen brakes, too, by tapping either the up or down shift paddles. The most aggressive setting will almost pull you up to a halt from urban speed without any brake pressure required.

The suspension of the EQC feels more settled than the last GLC I drove, and that could be in part due to the extra weight and stiffness of the battery cell under the body. The centre of gravity feels low, and it feels stuck down to the road in most situations.

The ride is mostly fine, but with big 20-inch wheels and low profile tyres, it can jar on hard edges. I also noticed that it can feel a bit unsettled at higher speed, as the body moves around - from side to side - more than I would have expected. It deals well with undulation changes and big dips, and if the surface is good, so are the comfort levels in the cabin. 

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. 

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.

It mightn’t have the same method of propulsion as a petrol or diesel Merc, but it has similar service requirements. You still need to take it to the workshop for maintenance every 12 months - or every 25,000km! - whichever comes first.

Owners can either pay as they go for servicing, or pay up front and bundle it into their finance. The upfront rate is $1350 for three years/75,000km. Pay as you go will peg you along at $450 (year one), $750 (year two), $450 (year three). 

When the EQC launched it came with a three-year/unlimited kilometre warranty plan, but that was recently updated to a five-year/unlimited km plan, bringing Benz inline with the likes of Korean luxury maker Genesis, not to mention the majority of mainstream car brands.

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.
