BMW IX vs Mercedes-Benz EQS53

What's the difference?

BMW’s iX M60 isn’t just the brand’s flagship all-electric SUV, it’s a statement that the electric future is here and it doesn’t have to be boring.

Pricing aside, the top-spec iX serves up practical space and prodigious performance in a package that is punctuated with panache.

The sizeable battery also allays any concerns over range, while the cabin’s appointments and fit and finish are definitely befitting of a BMW.

It’s not designed to be for everyone, and that’s okay, too, because the small customer base willing to part with around $230,000 for an electric SUV in 2022 will find a lot to like about the iX.

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.

Close your eyes and ask your eight-year-old self what an electric BMW SUV would look like, and chances are something like the iX will come to mind.

Sleek and slender, but still very BMW is the best way we can describe the iX.

Of course, we cannot talk about styling on a BMW without mentioning its front grille.

With a more vertically stacked orientation, the iX’s grille has been described as ‘toothy’ or even an ‘eye sore’ by the public in the past. But honestly, we think this attention-grabbing front end suits the swagger of the M60.

The gold highlights throughout are especially baller, and the grille serves as double-duty to hide a lot of the front-facing cameras and sensors required for more of the high-tech driving features like semi-autonomous driving.

The grille is flanked by BMW’s usual quad-headlight design for a menacing appearance on the road, and we particularly like the contrasting colours and sharp lines of our grey-coloured test car.

Another cool feature is the front badge, which can be popped up and serves as an inlet for the windscreen washer jets.

In profile, the 22-inch wheels look almost too small against the huge swathes of bodywork, but BMW has done a good job in slimming down the M60 thanks to the gloss-black stripe that runs along the bottom of the doors.

Speaking of, the handles might not pop-out like some of its rivals, but the recessed handle is highlighted nicely with gold-copper accents that also run along the beltline and door mirrors.

The D-pillar is also broken up with a blacked-out section that divides the roof, also helping slim down the behemoth BMW, and up close the section is embossed with ‘iX’.

At the rear, the clamshell boot might look large and bulky, but the design is helped by the very slender tail-lights and bumper broken up with more gloss-black.

Step inside the cabin, and the iX’s aesthetics are similarly unconventional, but the interior design also follows function.

For starters, the odd-shaped steering wheel is the feature that stands out the most, but you quickly realise the flat bottom helps with entry and exit into the driver’s seat.

As an all-electric model, there is no transmission tunnel, with the footwell between the driver and front passenger easily accessible for a more open-feeling cabin.

There is an armrest of course, while the area for multimedia controls is adorned with a one-piece, wood-like finish to contrast the crystal control knob. It’s a mix of technology and the natural environment, you see, much like the iX itself.

Do we love the styling of the iX M60? Much in the same way Louis Vuitton’s latest fashion range might not appeal to the masses, the iX M60 is likewise a polarising proposition.

To answer the question, yes, the iX M60 is a very stylish SUV that draws the eye and turns heads like nearly nothing else on the road – and that is exactly the point.

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.

Despite what it might look like on the outside or how it drives behind the wheel, BMW’s iX is undoubtedly a large SUV in shape.

Measuring nearly five metres long, and featuring a 1967mm width and 1696mm height, the iX M60 is certainly a sizeable machine.

However, it is the three-metre long wheelbase that is the most important measurement here, as it enables a vast and expansive interior space fit for the family.

The front passengers have ample room to get comfortable, and like we said in the design section of the review, there is nothing dividing the footwells of occupants up front.

This makes it the perfect place to park a backpack, handbag or even nappy bag when on the go, and means the front passenger doesn’t lose out on any legroom.

Even the armrest affords storage solutions for all the little things you might have you in pockets, while a wireless smartphone charger means you always have somewhere to place your device.

The front seats, finished in a quilted leather, might look plain, but are wonderfully supportive – even when the speedo climbs and you're carving up corners.

And in the rear, the story is largely the same, with seats that look and feel great and plenty of room for passengers to get comfortable.

My 163cm frame had no problems with leg-, head- or shoulder-room, but the base middle seat is raised a little.

We’ll also call out the great way BMW has hidden the ISOFIX mounting points for child seats, which is hidden by a flap that can be raised or lowered depending on what is needed.

It’s an elegant solution to something that can be an eyesore in other models, and shows the lengths BMW has gone to for the little details.

There is also a fold-down armrest for passengers back there, while the back of the front seats feature two USB-C charging ports, map pockets and spots to insert entertainment screens. 

Open the clamshell boot and there is a cavity that will swallow 500 litres of volume, plenty for a small family like ours, with the charging cables hidden neatly under the floor.

The boot floor is very long, too, meaning large objects will easily fit into the rear, while the 40/20/40 rear seats can be folded down to increase carrying capacity to 1750L.

To put that into perspective, something like the Ford Ranger is rated for more than 1200L in its tray, and while we would never condone the use of an iX to carry worksite tools, it does make carrying a surfboard or Ikea furniture that much easier.

However, it's worth pointing out that there is no front trunk in the iX, as there are electric motor and mechanical bits found in there. 

It’s just a shame that in a car of this size, BMW has not managed to position things with room left for a bit of usable space under the bonnet.

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.

A large part of why the iX M60 is so much more expensive than its siblings, is because of its powertrain.

With two electric motors spinning all four wheels, the iX M60 makes a staggering 455kW of power and (are you sitting down?) 1100Nm of torque.

This means the iX M60 can accelerate from 0-100km/h in just 3.8 seconds. Not bad for a 2.5-tonne SUV, and it puts many petrol-powered rivals to shame.

This also makes it much more potent than the xDrive40 (240kW/630Nm) and xDrive50 (285kW/765Nm), while also blowing away the Audi e-tron S (370kW/973Nm).

The only electric car that comes close right now in Australia is the Porsche Taycan Turbo S (560kW/1050Nm), but the Tesla Model X Plaid supposedly makes 760kW/1020Nm from three electric motors.

And while the Tesla is not yet available, the Taycan Turbo S is more than $100,000 pricier than the iX M60, and doesn’t offer the same levels of practicality.

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.

Equipped with a 112kWh battery pack, the iX M60 features 566km of driving range according to the WLTP cycle.

In reality, we saw closer to 540km of driving range on the dash readout with a full charge, but of course this is all subject to things like the level of regenerative braking you apply, ambient temperature, the driving mode chosen, air conditioning and weight.

Officially, the BMW iX M60 consumes 26.5kWh per 100km, but our week with the car saw an average of 25.6kWh/100km with driving mainly focussed on short, inner-city trips that are advantageous to an electric car.

This betters the energy consumption of models like the Taycan Turbo S, which features a combined-cycle test of 28.5kWh//100km, but is much more energy-hungry than something like a Nissan Leaf (18kWh/100km).

This figure is also very dependent on driving style and environment, but for a 2.5-tonne SUV that will ferry the family and more, consumption isn’t too bad.

Charging options include 11kW for AC and 200kW DC fast-charging – the latter of which can juice the iX M60 from 10-80- per cent capacity in just 35 minutes, if you can find a compatible outlet, of course.

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.

Maybe it’s just us, but as soon as we step into the driver’s seat of the iX M60, the “Gotta Go Fast” theme song for the Sonic the Hedgehog cartoon just comes to mind.

And that’s probably because this BMW all-electric SUV seems to want to do one thing... go fast.

Sure, there are various driving modes on offer, including 'Sport' and 'Efficient' (as well as 'Expressive' and 'Relax', weird names, but okay BMW), but no matter what mode you are in, there is just an eagerness and urgency in the iX.

And this feeling of immediacy isn’t just because the iX is an electric car. We’ve experienced that before in other EVs. This is because it’s an M-badged BMW.

The iX M60 is wonderfully responsive to throttle inputs, and the 1100Nm (!) available makes it almost comical getting up to speed from a freeway on-ramp.

And in day-to-day traffic situations, it feels like you’ve got cheat codes on while driving.

Waiting to turn into traffic and see a gap that you wouldn’t normally be able to squeeze into? The BMW iX M60 can do it.

How about cruising along and need to change lanes, so you nudge forward a bit for the opening in traffic? Put the foot down and in the span of half a second, the BMW iX M60 has surged forward enough to flick the indicator on.

And take the iX M60 out to some twisties and that brute force will get you to the end of the road in a time you didn’t think was possible in a 2.5-tonne large SUV.

It’s almost unfair how the instant torque makes it everything so much easier on the blacktop.

But that eagerness is a double-edged sword, as when you want things to calm down and operate the iX in the smoothest manner possible, it’s harder than you might think.

Because the throttle is so sensitive and the powertrain so potent, even the slightest twitch of the right foot can lead to a quick burst of speed that knocks you back into your seat.

Even with things dialled down to the Efficient drive mode, it didn’t do much to curb the unruly iX M60 from wanting to break free at the first moment of carelessness.

Don’t get me wrong, it never gets dangerous or unpredictable, but it’s a bit like toilet training a toddler – you’ve always got to be on top of it.

And for some, that’s fine, but for others when you’ve just had a full-on day at work and have to commute home to the family, it can get tiring. 

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.

Like all new BMWs, the iX now comes with a five-year/unlimited kilometre warranty with roadside assist over that period.

BMW held out at three years/unlimited km long after competitors had moved to five years. But this finally matches the assurance periods offered by premium rivals Audi, Genesis, Jaguar, Lexus, and Mercedes-Benz, and is up two years from the BMW warranty offered just earlier this year.

The iX uses BMW’s 'Condition Based Servicing' system, which means the vehicle will notify owners of when it needs maintenance, therefore there aren’t any scheduled servicing intervals.

However, services are bundled into four- and six-year plans, priced at $1520 and $2195 respectively. An annual average of $380 for the former, and $367 for the latter, is competitive in this part of the market.

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.
