Mercedes-Benz Eqb250 vs Mercedes-Benz EQS

What's the difference?

The EQB is a likeable yet complicated machine.

On one hand, the high pricing is a real hurdle, even in the base 250, while the 350 4Matic costing the wrong side of $110K driveaway can’t even be had with seven seats. What is the point of it? 

On the other, though, the EQB is roomier than its appearance suggests, way lovelier inside than anticipated, and – especially after allowed to really be driven hard and fast – a whole lot more Mercedes-Benz in the way the 350 4Matic moves, steers, grips, rides and stops.

As a result, we’d skip the capable but bland 250 and try to haggle hard on the price of the altogether too-expensive yet compelling 350 4Matic instead. It’s the EQB to be in.

It’s unquestionably fast, certainly luxurious, but I’ll be honest, I don’t think the EQS is going to be for everyone. The styling will be challenging for some and the glittery interior tech offering might be a bit much, even for the more rusted-on Benz traditionalists.

Then again, shouldn't an electrified flagship be all about challenging the status quo, trying new ideas, and bringing new fans to the brand? If anything, I think that might be what the EQS does best.

The EQB does not employ a dedicated EV architecture – sometimes referred to as a ‘skateboard’ platform – like the Tesla Model Y, or for that matter the brilliant Hyundai Ioniq 5, Kia EV6 and Genesis GV60 at around the Benz’s price points.

By this, we mean that it was originally designed as an internal combustion engine (ICE) vehicle. In this case, what lies beneath is the MFA2 platform, first seen in the redesigned A-Class hatch back in 2018, and applied to all transverse-engined Mercedes models since.

The upshot here is that there are some compromises as a result compared to the aforementioned EV-only alternatives, namely concerning packaging as well as weight distribution in some cases.   

Like we said earlier, the EQB’s design is eye-catching and quite handsome. It is clear that the success of the GLB that spawned it is partly attributed to the chunky, almost function-over-form tall-boy utilitarian styling. That ‘W’ shaped window-line kink is an interesting visual feature too.

The changes from GLB to EQB do give the EV definite points of difference, from the front-end’s black flat panel and fibre optic light that connects the (blue-highlight) headlights, to the curved strip LED tail-lights and bumper-sited numberplate mount.

We reckon the 20-inch AMG turbine wheels really do enhance the EQB aesthetically as well, but of course they’re an option on the 250. Though probably not in Gold Rose.

We’re going to start with design, because from the outset it is a topic which simply must be addressed.

Mercedes has flipped the script when it comes to its next-generation design language worn by its dedicated range of ‘EQ’ electric cars. It follows a trend we’re seeing across the industry of larger, more amorphous vehicles which need the space to accommodate batteries, but also the aerodynamic traits to extend driving range and keep energy efficiency as high as possible.

The issue when it comes to the EQS is it essentially puts the iconic S-Class shape, refined over generations, in the bin, and replaces it with something a bit more challenging to the eye.

Gone are the angles, louvres, and deeply three-dimensional grilles, replaced by sleek rounded edges, wheels which reach to the very edges of the chassis, a blank, almost plasticky grille and a more liftback-like profile than one of a traditional sedan.

You’d better get used to it, too, because the smaller EQE is near identical in shape, a trend which will no doubt continue across other EQ models.

It’s the finer details that add character, particularly for the 53 with its AMG-leanings. The lack of shapeliness down the side makes the massive 22-inch wheels stand out more, and the rear three-quarter might be this car’s best angle, with a colour-matching spoiler flicking up off the small bootlid, and delicate badgework illustrating this car’s place in the world. Our car, which appeared in a silver shade timeless on Mercedes-Benz models, made the black AMG highlights on the front and rear bumpers shine, and some of the usual Benz shape is claimed back through the EQS’s LED light profile, both at the front and rear.

There’s no doubt it’s a step into the future, and an overall shape which is a marriage of both form and function. While looks are always subjective, I still think it may be a hard sell, even to some of the most committed fans of Mercedes design.

As with the popular GLB that spawned it, there’s more to the EQB than meets the eye.

Photos mask the German electric vehicle’s considerable length and height as well as the substantial space offered inside, giving the Mercedes a handy advantage compared to premium alternatives like the Volvo XC40 Recharge, the Genesis GV60 and BMW’s recently announced (and quite handsome in the flesh) iX1 due early next year.

In fact, the EQB’s lengthy 2829mm wheelbase accommodates the batteries as well as impressive cabin packaging flexibility. Its 4684mm body is actually 26mm longer and 37mm higher than the larger, current-shape (X253) GLC, though width is identical to the EQA, making this a long, tall but quite narrow SUV proportionally speaking.

That expansive feeling is boosted by deep side windows offering reassuring all-round vision, boosted by an excellent driving position. All launch vehicles had the AMG sports seats (optional on the EQB 250, so we can’t speak for the base model), but as tested, they provided hours and hours of comfort and support. Loads of adjustability also help.

The EQB’s dash design is attractive and contemporary, though it can also seem daunting at first, requiring time to learn and understand where all the switchgear and controls are. The ‘Hey, Mercedes’ voice command mostly works well, too, and can provide additional tuition. The multimedia screen can be swiped like a tablet/iPad, or controlled via a fiddly touchpad on one of the steering wheel spokes.

Once mastered, the layout is logical and operation clear… with the exception of the drive selector on the right-hand side, which can be confused for an indicator and so knocked out of ‘gear’ and into Neutral on a regular basis. This has been a two-decade-long criticism of Mercedes models.

As with most MFA2 vehicles, the interior design and quality are a big step forward compared to earlier efforts. Multi-configurable digital instrumentation (including an elegant uncluttered mode), gorgeous turbine-look vents, a row of classy toggle switches for the main buttons and a great steering wheel are highlights to behold. Storage seems endless, reinforcing the practical nature of this cabin.

Speaking of which, stepping into the rear (second row) seats further underlines the EQB’s spaciousness. Entry/egress is easy due to wide-opening doors, taller folk should find ample room for knees, legs and (especially) heads, and the (slightly reclinable) backrest does its job. Comfy if firm cushions also slide forward (by up to 140mm) when required.

That’s to aid third-row access (where applicable). To that end, the second-row seats also tilt to allow people to squeeze past. Note, though that this is really a kids-only area, rated for occupants no taller than 1.65 metres. Surprisingly cosy, both chairs are OK for short trips, but longer ones would be a stretch too far except for the smallest passengers. 

Keep in mind that all outboard middle and rear seats where fitted have ISOFIX latches for child seats.

Luggage space is another EQB bonus, offering 130 litres with all seven seats up, or 495L with the third-row folded. Drop the middle row and there’s 1710L (or 1620L in seven-seater versions). These figures are between 20L to 60L down compared to the GLB.

Note, too, there is no spare wheel fitted. Just a tyre-repair kit.

The EQS is enormous, so it’s a good thing there’s huge amounts of interior space, even for what is ostensibly an S-Class, and with its bespoke electrified underpinnings, it also scores the kinds of innovations we like to see from electric cars.

These include things like a huge cutaway under the floating dash for extra storage, which the brand has seen fit to add elastic tie-downs so your objects don’t go flying in corners!

Storage up front is otherwise excellent with decent bins in the doors with height-limited sections for bottles, a flip open tray which houses the wireless charger and a set of fold-away bottle holders, and split-opening armrest console box which is deep and features yet another set of USB-C outlets.

Adjustability is great for front passengers, but ergonomically I found something a little weird about the digital dash. For me to rest my arms and hold the wheel, I had to set it so low the top of the wheel obscured the instruments, and if I set it high enough to see the full cluster, to comfortably hold the wheel my elbows would need to float above the armrests. Weird.

It doesn’t end there for the entirely touch-based controls either. While the (admittedly very cool-looking) wheel is packed full of buttons and touch sliders, they require near-surgical precision to operate with your thumbs, distracting while you’re driving, and the enormous centre screen’s main drawback is the fact CarPlay, for example, was not designed for the buttons and functions on the far left to be a metre away from where the driver’s hand is. Again, it’s distracting to have to lean out of your seat to hit the ‘back’ button on most context menus.

I would like to tell you at this point the Mercedes-Benz menus are mercifully simple to aid you with such an overwhelming system, but this isn’t true either. For some reason, there’s a ‘vehicle settings’ menu accessed easily through the main panel, or another menu with a separate set of key functions activated by a car-shaped shortcut button on the floating console. Why? Why aren’t these menus the same? I discovered this in my attempts to use the ‘raise vehicle’ function when faced with a steep driveway. You’re going to need to use this function often in a car measuring over 5.2 metres long, so hiding it in a confusing menu is an interesting choice.

The back seat is where the EQS should shine, and in terms of space it’s stellar. I can barely touch the seat in front of me when set to my own (182cm tall) driving position. It comes with some soft pillows which attach to the headrests, the sunroof extends back there nicely while not impeding on the great headroom, and the lavish trims all continue into the doors and seat bases, too.

The drop-down armrest has a trick pop-out bottle holder in it, and there are a further two on the doors. Amenity-wise rear passengers score four adjustable air vents with two climate zones adjusted via their own touch-panel, but I was interested to see there was a lack of screens back there.

This is particularly notable as most S-Classes are bought to be driven in rather than to drive, and the screens are so much in the front, I was expecting a matching offering for rear travellers. Not so.

You also can’t adjust the rear seats at all, and unlike some EVs coming out in this space, there’s no recliner mode for the full business-class experience.

The boot is much larger than in the smaller EQE, with the EQS making use of its extended dimensions nicely. The floor is fully flat, and has a secret compartment underneath for the storage of both your included Type 2 to Type 2 public AC charging cable, and Type 2 to wall-socket converter for garage charging.

With a total space of 580 litres, the EQS comfortably consumed our entire CarsGuide luggage set with space to spare.

At a whopping $328,400 before you start ticking options boxes or apply the necessary on-road costs, the EQS 53 is at the pointy end of the price scale, even for an electric car.

Dig a little deeper though, and there are some surprises. For example; this top-spec EQS still manages to be more affordable than the top-spec combustion S-Class ($335,100) and when compared to its rival from Porsche, the Taycan Turbo S ($351,000), it comes out with a cost-advantage.

It is significantly more expensive than BMW’s electric flagship, the upcoming i7 sedan, which starts at $297,900 before on-roads for the xDrive60.

Still, falling between BMW’s core EV offering and the Porsche Taycan is a fitting sweet-spot for our Mercedes EQS.

Equipment is out-of-this world, with the EQS not only having ridiculous performance figures we’ll talk about later, but also standard four-wheel steer, all-wheel drive, adaptive suspension, full leather interior trim with multi-way adjust for the front seats, complete with heating, cooling, and several message programs.

It also has the (again, completely over-the-top) 1.4-meter long MBUX ‘Hyperscreen’, which is made up of two large screens for the instrument cluster and passenger touchscreen, as well as an enormous centre panel for the climate and multimedia functions, wireless Apple CarPlay and Android Auto connectivity with matching wireless phone charging bay, augmented reality sat-nav, a panoramic sunroof, LED headlights, LED interior lights with selectable RGB settings, and an auto tailgate.

Enough stuff for you? Wait! Says Mercedes, there’s more! The Dynamic Plus package ($7690) boosts performance even more and adds an extended cooling system and launch mode, an aesthetic Night Package ($3990) which adds mainly black and chrome trim pieces as well as 22-inch wheels, ceramic composite brake package ($9990), augmented reality head-up system ($2690) and a wall box home charger ($1450).

Plenty for buyers to work with then. For now though, they’ll only be able to choose the top-spec AMG-tinged 53 version, as lower grades are yet to arrive in Australia. It will be the same for the smaller but near-identically specified EQE 53 when it arrives in Australia, so the message is pay big or go home to get on the latest EQ tech early.

As with the related EQA, the EQB uses an asynchronous motor and a single-speed reduction gear transmission under the bonnet to drive the front axle. In the 250, it makes 140kW of power and 385Nm of torque.

Moving on to the 350 4Matic, it delivers 215kW and 520Nm, since a second permanently excited synchronous motor is fitted on the rear axle. This slashes the 0-100km/h acceleration time from 8.9 seconds to 6.2s, though both offer a 160km/h top speed.

This is despite a heavier kerb weight (2153kg, up from 2059kg). Power to weight ratio for the 250 is 68kW per tonne, compared to the 350 4Matic’s 99.9kW/tonne. That second motor sure makes a difference!

Both models use a 66.5kWh lithium-ion battery pack fitted between the axles, with a maximum 11kW AC and 100kW DC charging capability.

As with most electrified MFA2 models, front suspension is via MacPherson-style struts while the rear brings a multi-link arrangement. Steering is by electrically assisted rack-and-pinion.

In the electric era, do performance figures matter? AMG would argue a resounding ‘yes’ although I would argue the art for premium automakers like Mercedes is now in producing suspension setups that can handle the weight of batteries.

Regardless, the EQS has a dual-motor setup, capable of providing a whopping 484kW/950Nm in its standard form, or an even more incredible 560kW/1020Nm with the Dynamic Plus package. Look, you’re spending over $328,000 already, what’s an extra $8k or so to put pretty much any other four-wheeled object in your rear-vision mirror? With the Dynamic Package, a sprint time of 3.4 seconds is… brutal.

The four-wheel drive system is necessary to keep all that power under control. While some enthusiasts may be turned-off by the four-wheel steer function, I’d read on to the driving section to see why it’s not only worth having (try turning a 5.2-meter long sedan around without it) but also not as intrusive as you think it’s going to be in the corners.

Using WLTP figures, the EQB 250 has a combined consumption rating of 20.4kWh per 100km, down from the EQB 350 4Matic’s 21kWh/100km.

Maximum range is rated at 371km and 360km respectively. Note that due to challenging flood-water and torrential rain weather conditions, on-road real-world figures were not available during the launch drive.

The EQB offers varying levels of energy recuperation to help recharge the battery pack. In ‘D Auto’ it figures out the level of resistance automatically, but drivers can also choose to do this manually via ‘D+’ that provides coasting, ‘D’ that brings mild regeneration off-throttle, and ‘D—’ that activates maximising regen for close to single-pedal driving. These are paddle activated.

Cables for home charging with three-prong outlets are included – an eight metre long one plus a five metre public charging cable.

Mercedes says that using a 100kW DC charger will take an EQB from 10-80 per cent charged in 30 minutes, while an 11kW AC public outlet needs 4.1 hours and at home using a regular 3kW 10-amp socket requires at least 25 hours.

Even at the official energy consumption of 23kWh/100km, the EQS’ drivetrain is essentially the electric equivalent of wielding a massive V8 under the hood. It’s not by any measure impressive, but then, with 107.8kWh of lithium batteries under the floor, it’s perhaps impressive it’s not worse than an Audi e-tron, particularly since the EQS weighs in at nearly three tonnes.

The battery is one of the largest on the market in Australia, offering the EQS a driving range of 585km on the WLTP cycle. Very impressive.

On the charging front, the EQS can charge at up to 200kW on DC thanks to an advanced cooling system, and on AC charges at 11kW in its stock form or 22kW with an optional $2490 upgrade. Again, at $328k, why wouldn’t you want the best charging system you can get for so little extra?

You can also package in a Mercedes-Benz branded wallbox for your home garage, valued at $1450 before installation costs.

To give you an idea of charging times: Expect a little over two hours (from 10 per cent) on a common 50kW DC public charger, nearly ten hours from an 11kW AC public charger, and a number not even worth mentioning from a home wall socket.

The most remarkable thing about driving the EQB is how similar the 250 and 350 4Matic seem initially, until when push comes to shove.

Around town, both rise up to meet brand expectations. Easy and smooth off the line, acceleration is sufficiently brisk in the 250 and noticeably stronger driving the 350, as you’d expect in a two-motor EV. Progress is spirited, smooth and refined.

We're also grateful that the engineers seem to have cheekily dialled in connected and agile steering, imbuing the EQB with a likeable athletic attitude that’s just right for weaving in and out of tight traffic spots. Which is quite a feat really, given this car’s substantial size and mass.

Perhaps more surprising is how settled the ride is, no doubt aided by the sheer weight of these two-tonne-plus SUVs, as well as the standard-fitment adaptive dampers. Most bumps are quietly and effectively absorbed.

Out on the open road, the 250 remains sufficiently powerful, offering decent throttle response and quite a relaxed cruising gate. However, if you’re expecting Tesla-matching neck-snapping mid-range thrust, look elsewhere. Same applies to the other model. Though undeniably stronger throughout, not even the twin-motor 350 4Matic can be classed as especially quick.

However, while both EQBs display beautifully balanced steering that go exactly where you need them to be, only the 350 4Matic has the muscle to really explore the lofty dynamic capabilities available at higher speeds.

Across water-logged and desolate rural Victoria, the EQB behaved with exceptional athleticism given its role in life, providing outstanding steering precision, matched by brilliantly reassuring control. We’re talking planted confidence, as the 350 4Matic has the ability to really come together and move with the ebb and flow of a fast country road with outstanding aplomb. Despite teeming rain at times, the Mercedes behaved like you’d hope a swift, safe and sound grand tourer would. Who'd have figured?

Back on the highway, there was plenty of road noise intrusion coming up through the tyres, but otherwise, it seems obvious to us that though you pay more, you do get more with the twin-motor AWD version.

The EQS is quite surreal to drive, and you’ll notice a whole bunch of odd things first.

Immediately the driving position will be surprising. It’s nothing like what a traditional sedan feels like. This is because you sit high in the EQS. This helps facilitate extra under-floor space for the batteries, but the way Benz puts it, this driving position is deliberately SUV-like to grant buyers the more desirable view of the road which they now (apparently) seek.

It has some oddities, as mentioned earlier, with the fixed digital instrument cluster, and the way the wheel can block it depending on your height, but on the whole I found visibility in the EQS to be pretty good, despite limitations out the distant rear window.

Sound-wise AMG has created a bespoke soundscape for its electric models, two soundscapes, in fact. One sounds like a facsimile of a distant, digitised, V8 (weird) while the other is a bit more sci-fi. I can’t decide which one I really like, but props to the brand for thinking of individual sounds for things like accelerating, regenerative braking, as well as turning the car off and on. There’s even a humming tone for when the car is idling. 

AMG says “it doesn’t work without sound” and I suppose it does add some sort of feedback to the experience which would otherwise be missing. I’d rather have it than not I suppose is the take-away here.

The acceleration is completely over-the-top in Sport or Sport+, allowing you to move such a large vehicle forward in an almost comically quick fashion. It has the sudden urge of a Tesla, but with an element of grace that follows courtesy of the adaptive suspension which, not only settles the ride, but keeps the car comfortable.

It is the suspension though which sets cars like the EQS (and even rivals from BMW) apart from the likes of Tesla. The ride in the EQS is superb, befitting the heir apparent to the S-Class throne. It’s hard to find a ride so void of issues, particularly in the everyday Comfort drive-mode. It’s not just the fact I can’t complain about brutality from this car’s oversized 22-inch wheels, but also there has clearly been delicate work conducted to control the rebound, body-roll, and jiggle which can occur as a result of moving around a near-three-tonne chunk of aluminium, steel, lithium and leather at enthusiastic speeds.

This settled ride combines gloriously with the four-wheel steer system to make the EQS a keen corner carver, despite gravity constantly working against it.

I was surprised to find the four-wheel steer system to be pretty much identical in feel to the system also employed in the EQE and new C43, in that it is unobtrusive to the overall feel of the car, only helping to add a little extra turn-in to the corners when need be.

In a vehicle as long as the EQS it’s a bit more noticeable, and requires a moment of brain-adjustment, as the car (bizarrely) goes exactly where you point it, requiring no over- or under-adjustments, the grip from the enormously capable four-wheel drive system refusing to let any shift under sensible driving conditions. 

So, it’s comfortable enough to be an S-Class, fast enough to be an AMG, but I must say there is something a bit clinical about how it attacks the road. Missing some of theAMG drama we’ve become so used to from the brand’s combustion range, perhaps?

The S-Class has always been a safety leader, and it appears the EQS is no different.

On the active front expect Autobahn-speed auto emergency braking with pedestrian and cyclist detection, lane departure warning with lane keep assist, blind spot monitoring with rear cross traffic alert, traffic sign recognition and driver monitoring.

The Mercedes semi-autonomous adaptive cruise control suite is just as good (perhaps better in some areas like distance control) as the stuff from Tesla in my experience, and this car also had a notably comprehensive 360-degree parking camera which is brilliant enough to show you the top-down and full rear view cameras all in one screen.

The EQS is yet to be officially rated by our local crash authority, ANCAP, but it received a maximum five-star Euro NCAP safety rating in 2021.

Mercedes-Benz offers a five-year/unlimited kilometre warranty. The battery pack warranty is also industry-standard, valid for the usual eight years/160,000km.

Service intervals are every year or 25,000km. The EQB Service Plan starts at $1625 for the first three years, $2225 for four years and $2650 for five years.

Like many electric cars, the warranty on the EQS is twofold. Firstly, there is the whole vehicle warranty, which from Mercedes-Benz is five years and unlimited kilometres, but the high-voltage battery is covered by a separate, and quite healthy, ten-year, 250,000km promise.

Benz throws in a three-year subscription to ChargeFox, offering owners free charging for the duration (to give you an idea, it cost me about $30 to charge the EQS to nearly full from 20 or so per cent).

Service intervals are surprisingly standard, at 12 months and 15,000km, and the EQS’ pre-paid service program is $1750 for three years, $2750 for four years, or $3250 for five-years, working out to about $650 a year. Far from the cheapest we’ve seen for an EV, but chump change for owners considering the up-front cost of this vehicle.
