Mercedes-Benz EQS vs Cadillac Lyriq

What's the difference?

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.

It's got a couple of quirks, but the Cadillac Lyriq is a pretty convincing, and definitely American, take on a premium electric vehicle in Australia. The only issue, I think, is that, while the brand is obviously iconic in the USA, it's not that well known in Australia, and we are a market now awash with pretty good, and often much cheaper, EVs from China. It's a hyper-competitive market. Only time will tell if Cadillac can convince Australians that its badge belongs among the European premium marques.

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.

The Cadillac looks… well, it looks American, right? A kind of difficult-to-describe Americanness that’s somewhere between an SUV and state car.

That’s not an insult, by the way. I personally think the Lyriq looks kind of pretty, with its bold elements countered by the surprisingly gentle touch applied in places, like its razor-thin daytime running lights (DRLs).

I’ve got to say, it doesn’t look much like any of the other new SUVs arriving, or a knock-off German brand. It’s got its own persona.

The cabin of the Lyriq is predictably plush, with comfy massaging seats, soft-touch materials and plenty of tech, but it is a little shiny and busy in places for my tastes. Minimalist this is not.

But I do like the fact that – when I’ve got Apple CarPlay hooked up – I can just leave the screen be. My driving stuff is accessed by the wheel, and everything else I want is accessible through physical buttons.

There are some strange elements, though. The grab handle on the driver’s side, which isn’t replicated on the passenger side, is odd, and likely a byproduct of the factory moving the steering wheel. Some of the central storage bins are too small to be really useful, and I hate gloveboxes that can only be opened through the screen.

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.

It’s a big boat, the Lyriq, stretching more than five metres long and almost two metres wide. That’s not much shorter than, and in fact slightly wider than, something like a Nissan Patrol, just to put it into perspective. Though of course it’s nowhere near as high as a proper 4WD.

Predictably, though, its dimensions mean plenty of room in the boot, which opens to reveal a very useable 793 litres of luggage space. Drop the seats, and that number grows to a massive 1722 litres. 

But the Lyriq does without any spare wheel of any kind. A tyre repair kit is your only option.

Now, the backseat. And I know this is likely only of interest to parents of newborn babies, but that’s me, so I noticed. These are some of the best ISOFIX attachment points I ever used. Usually you’re fumbling around between the seat cushions trying to line up the latch points, but the Lyriq's solution — while perhaps not the most visually alluring – puts the brackets beneath plastic lift-up flaps, and they're so damn easy to use. 

But there are some quirks in the backseat, too. Those same ISOFIX attachment points, which are so great for baby seats, are less great for the adults actually sitting in the back. You can feel the hard plastic covers, and what feels like the bracing bar running across the backseat, beneath the cushions. It's not diabolical, and if you shift your rear-end forward slightly you can't feel it at all, but it's a strange quirk all the same.

Elsewhere in the backseat, there is plenty of room for backseat riders, and you can control your own temps, too.

You can have your Cadillac Lyriq in two flavours — the Luxury, yours for $122,000 plus on-road costs. Or the Sport, which is two grand more, listing at $124,000.

Perspective time. The new Polestar 3 starts at around $118k, but climbs to more than $130k for the dual-motor options. The similarly sized BMW iX starts at more than $140k, and the Mercedes-Benz EQE is north of $135k. So if you consider the Cadillac a ready-made premium brand, then its looking like a relatively sharpish one. 

Cadillac says the changes between the trims largely focus on the “aesthetic signature” rather than any major equipment differences. The Luxury gets chrome highlights, for example, while the Sport gets a darkened design theme, including the wheels, body highlights and windows.

Both trims are otherwise identically equipped, which means 21-inch alloy wheels, full LED lighting, an electric sunroof, an auto-opening boot and a touch-to-open charging port.

Inside, there’s a 33-inch digital dash, with Apple CarPlay and Android Auto, wireless device charging, a thumping 19-speaker AKG stereo and USB connection points galore.

The leather-wrapped front seats have heating, ventilation and a massage function, there’s heating and cooling for the window seats in the back, tri-zone climate control and there’s 126-colour ambient interior lighting.

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.

All Aussie Lyriqs are dual-motor affairs, with an electric motor at each axle producing a total 388kW and 610Nm, which in a car this big, which weighs just under 2.7 tonnes, is more than enough to get the Caddy up and moving, but not enough to make it feel like a supercar. The two motors mean AWD, 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.

The Lyriq is equipped with a 102kWh lithium-ion NCMA battery, which delivers an ok 530km on the combined cycle. I say 'ok', because the BMW iX offers 600km-plus, while the dual-motor Polestar 3 is more like 630km claimed. Energy consumption is a claimed 22.5kWh per 100km on the combined cycle. 

When it comes to plugging in, the Lyriq is set up for 190kW DC fast charging, with the brand promising 128km of range in 10 minutes, or 10 to 80 per cent in just under 30 minutes. At home, a 7kW wall ox will deliver more like 43km an hour.

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 first thing you notice behind the wheel of the the Lyriq is just how whisper-quiet it is on the road. Cadillac makes a big deal about its 'Active Noise Cancellation' tech that's deployed here – it uses sensors to monitor road vibrations and the like, and then uses the car's stereo to create what it calls an 'anti-noise' signal.

It all sounds pretty high-tech and complicated, but it also works, with the Lyriq a seriously quiet and composed way to get around, with only the artificial EV noise really noticeable in the cabin.

Even travelling past freeway speeds, the Lyriq remains quiet, which does lend the whole experience a sort of premium vibe.

The Cadillac is also one of those cars that thinks solidity means premium, from the solid 'thunk' of the doors shutting to a general heft and weight to the steering, there's nothing feather-light or agile about the Lyriq experience, but it does all feel a little artificial, and like it's trying to be heavy on purpose.

The Lyriq, then, is no out-and-out performance car – it's 2.5-tonne-plus kerb weight and Olympic swimming pool dimensions largely put an end that – but it's more than brisk enough to get up and moving, with its twin-motor powertrain finding grip even in slippery conditions. It's brisk, but not brutal.

The Lyriq hasn't been tested or tuned in Australia, but happily it doesn't have that floaty, wafty suspension style so popular in the USA. This one feels to have at least had an international tune, which removes some of that marshmallow softness and makes you feel connected to the road.

The steering, too, feels direct enough and easy to predict, and the overall impression is one of quiet, calm motoring, which is probably what it says on the tin of any premium vehicle.

The Lyriq hasn’t been crash-tested in Australia, but it did get a five-star equivalent in American testing. There’s autonomous emergency braking (AEB) with pedestrian protection and junction assist, as well as active blind spot monitoring and assist. There’s also a side bicycle alert to stop you opening your door into someone, rear pedestrian alert, adaptive cruise and a total eight airbags, including knee bags for the driver and front passenger.

Interestingly, the Lyriq ditches those annoying safety bings and bongs for a novel, and far less intrusive approach which involves sending gentle vibrations through, well, your backside if the vehicle senses incoming danger.

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.

Cadillac has built a pretty convincing ownership package around the Lyriq, which begins with a five-year, unlimited-kilometre warranty, and an eight-year, 160,000km battery warranty. Beyond that, you also get five years of servicing, and five years of roadside assistance, free. 

Then you get a year’s free public charging through the Chargefox network and a free home wall box charger. If you have a wall box, or don’t want one, you can trade the home charging for an extra two years of free public charging.
