Mercedes-Benz Eqs450 vs Rolls-Royce Cullinan

What's the difference?

Does electrification enhance the seven-seat SUV experience? In the case of the EQS450, the answer is yes. Smoother, quieter and with plenty of easy-flowing power, the brand's family-focused luxury electric SUV behaves exactly as you might expect.

The Cullinan might not be the most beautiful or traditional Rolls-Royce, and it’s a shame modern success means providing an SUV option to everyone, but it’s still a remarkable machine, either to drive or just to sit in. It remains not just a marvel of engineering, but a marvellous of engineering. Hats doffed, old bean.

It’s a handsome SUV, and one that’s not immediately recognisable as electric — especially given there are little exhaust-pipe-mirroring design flourishes at the rear which make you look twice.

Aussie-spec cars get the AMG exterior treatment, which includes AMG alloys, aluminium-look side steps and the power-domed bonnet, but there's still nothing overly 'shouty' about the design, with the sleek, smooth body panels (accentuated by the hidden handles) making the EQS450 look smaller than it actually is.

Inside, it’s a super-comfy space to spend time, and the little fluffy pillows attached to the headrests should be standard in every car. The tech on offer is ample, too.

But it does all feel a little gigantic, with great swathes of wood panelling and massive screens, all of which make you feel bit like you’ve been shrunken down and are now living amongst the giants.

It is something of an achievement when a team of designers manage to make a facelifted version of a vehicle less ugly, daunting and disappointing than the original.

I thought the first Cullinan, launched five years ago, looked like a London black cab that had been mounted and inseminated by a double-decker bus. Big? Sure? Impressive? Yes. Beautiful? Only if you think Boris Johnson is sexy.

There was a lot of chat at the launch about the changes made for Series II, but in summary they tried to make it look more… like a boat, according to Exterior Design Lead Henry Clarke.

“We don’t look for speedy, overcomplicated lines, we take our inspiration from the luxury world, and it’s often from yachts, it’s that same sense of scale and grandeur, that’s the key to the timelessness of a Rolls-Royce,” he explained.

“We’re not focused on the world of automotive design, and if you look at the Cullinan it has that ethos you think of with a yacht, that strong, vital bow and then everything rearwards, the back of a yacht, has an elegance and grace to it.”

Fair enough, but what I appreciated was that they’ve squared the front end off a bit more, by outlining the grille, adding some gills beneath it and putting in some natty DRLs, and then rounded off the rear a little as well, so that it looks less… awful.

Indeed, after a couple of days of staring at it (and particularly admiring how good it looks in your rear-view mirror when behind you), I did come around to its looks. Certainly a lot more than last time.

And strangers driving past seemed to really like it, because they keep smiling and clapping at me. 

The EQS450 stretches 5136mm in length, 1965mm in width and 1718mm in height. That's about the size of a Nissan Patrol and long enough to make it a proper seven-seater.

The middle row can be adjusted forwards or backwards, and with the front seat set to my 175cm driving position, I found I had ample head and knee room to get comfortable.

USB-A charge points abound, and there's wireless device charging, and because of the sheer size of the cabin, the storage options are plentiful. The central bin between the front seats, for example, seems styled on the Grand Canyon.

In the third row, though, things get a little tighter, but it’s perfectly good for kids. My knees were touching the seat in front, however, and it still requires some acrobatics to climb into.

At the rear, with all three seats in place, you'll find 245L of room (measured to the ceiling), growing to a maximum 1030L with the third row flat. Stow the second row, and you'll find a maximum 2020L of storage space – which, and take my word for it – is plenty.

One small quirk, though. While the second row is electric, stowing away at the touch of a button, the third row isn't. That means, when it's flat, you have to climb into the boot to pull it back up, or attack it from the rear door. Either way, it's more awkward than it needs to be.

In terms of being a vehicle you might actually use - and keeping in mind that if you can afford one of these you’ve also got at least a half dozen other choices - every day, the Cullinan is the pick of the Rolls-Royce enclosure.

From the big boot space - 600 litres with the seats up, 1930 litres with them down - and its lovely little Viewing Suite, through the spacious rear relaxing zone to the absurdly comfortable and plush front seats, there’s a sense of grandeur about the whole Cullinan experience.

You can opt for a champagne fridge between those rear seats, if you like, or you can just lie back and stare at the blinking pins of light in your 'Starlight Headliner' and imagine that each one of them represents one of your millions, smiling down at you.

It’s a lovely place to be, in short, and with its super-thick double glazed glass, coated with an acoustic layer on top of that, and carpets thick enough to keep out road noise on their own, it’s also a very pleasantly quiet one.

Value? Price? What are these things you speak of, little plebeian person? Such is the disdain for such things at Rolls-Royce that they wouldn’t even tell us what the Series II is going to cost when it lands in Australia later this year. 

The people who can afford one don’t much care, of course, but for the rest of us, who like to shake our heads and make low, whistling noises, you can bet the price will rise just a little from where it was with the original Cullinan - and that was $705,000 for the basic car, or closer to $795,000 for the sportier, and blacker, Black Badge variant.

In terms of value, it’s hard to grasp that any car could cost that much, but for a Rolls buyer the equation is very different. They don’t need a Rolls, no-one does, but it makes a nice change from buying art works, gold or small countries. 

In terms of features, it has almost too many to mention, but let’s pause on the marvellous massage seats, the bespoke sound system, entirely unique to this case and built by Rolls itself, with incredible levels of detail, the Rolls umbrellas tucked into each door and the very lovely 'Viewing Suite'.

This consists of two pop-up seats in the rear, with a little champagne and canapés table in between, where “you can watch your children play football”.

Try that in Australia, at the rugby league, and you’ll be covered in half-time oranges and abuse spittle in no time. Stick to the polo, perhaps.

There are two electric motors delivering the driving power, one at the front axle and one at the rear, which will deliver a combined 265kW and 800Nm, fed through a single-speed transmission and with all four wheels being powered.

That's enough for a sprint to 100km/h of 6.0 seconds.

Rolls-Royce has committed to being a fully EV brand by 2030, so it’s a safe bet this Series II Cullinan will be the last one offered with its storming, staunch V12 engine. 

Indeed, Rolls hinted the only reason it hung around in this version is that this is only a mid-life face-lift for the Cullinan, and the car that replaces it will arrive on an entirely new, all-electric platform.

As good as the EV Roller, the Spectre undeniably is, driving this old-school Cullinan with its 6.75-litre twin-turbocharged V12 making the kind of thumping, torque-thick, nothing-is-too-much-trouble acceleration is a hoot.

It’s not loud, but it’s just loud enough that you can enjoy its deep, brassy tones, and it’s got plenty of power in reserve to hurl even this 2.75-tonne machine past lesser vehicles with ease.

There are two Cullinans to choose from, of course, with the base model providing a very pleasant 420kW and 850Nm or the sportier Black Badge version (Rolls calls it the brand’s “alter ego”) with 441kW and 900Nm. 

There's a huge 107.8kWh on board here, but the EQS450's driving range is a less impressive 483km. Maybe something to do with the 2918kg weight of this big SUV.

Don't get me wrong, 483km is plenty to cover almost anyone's weekly commute (and then some), but early promises had pointed to a range of more like 600km.

When it comes time to plug in, you'll find the EQS450 is set up for 200kW DC fast charging, which should see you go from 10 to 80 percent charged in just 31 minutes.

Home charging is, of course, a slower proposition. A three-phase 11kW supply should take 10 hours, while a 7.0kW wallbox will be slower again, and more like 15 hours.

Rolls-Royce claims the Cullinan will provide you with between 16 litres per 100km and 16.8L/100km, but I believe you’d have to drive it quite steadily to achieve even that quite appalling figure.

Twelve cylinders, 2.75 tonnes, you do the math, but it's interesting to note that with a nearly full tank - and we’re talking 100 litres of fuel - my distance to empty was looking like barely more than 500km - that’s an EV-like number.

The drive experience is, well, unremarkable. But I don’t want that to sound negative, because that's not how it's intended.

The EQS450 SUV does exactly what you expect a circa-three-tonne, premium electric SUV to do, and it does it all well.

It's powerful enough without being exhilarating, comfortable enough, and laden with enough tech to satisfy almost anyone.

It's just that it also doesn't exactly ignite the senses. But the question must be asked, what seven-seat family-focused SUV does? Few, if any.

So, surely the real test is if electrification has improved the formula here, and I'd argue that it definitely has.

For one, the EQS450 is properly whisper-quiet in the cabin, with Benz employing multiple sound-deadening techniques at once to lock out road noise. And with no pesky engine to interfere, the cabin is about as serene as they come.

The power delivery is predictably smooth and easy, too. There is no headline-stealing acceleration figure here, but the power is potent and plentiful, and more than enough for any real-world situation you might encounter.

The ride, too, is commendable. Aided by Mercedes' air suspension, it glides over all but the most broken road surfaces. And it is fitted with rear-axle steering, which really does cut down a turning circle that would otherwise surely resemble that of a cruise ship.

It feels heavy at times, though, and even the most high-tech suspension can't eliminate body roll entirely through tighter corners (physics and all that).

But unless you're really pushing – and why would you be – the cabin is calm, comfortable and cosseting.

So, exciting? Not really. But comfortable and calming, which are probably the traits its owners will value much higher.

The first word that comes to mind when describing the experience of driving a Rolls-Royce the size of a small housing estate is 'intimidating', because it's one of those cars where you take a few deep breaths before setting off (while muttering “please don’t crash it”) and then some sharp intakes of breath the first few times you find cars coming towards you on a narrow road, of which there are many on Ibiza where we were summoned to drive it.

I followed a panicked young man from India who had never driven a Rolls, nor a left-hand-drive car before, and boy, he sure looked intimidated, even if he didn’t ever get above 30km/h.

The incredible thing about the Cullinan, however, is how quickly it relaxes you and how astonishingly light and easy it is to drive. The steering feels almost absurdly light at first, you really can drive it with just one finger, two if you’re feeling cautious, but once you get used to it it just feels very Rolls-Royce.

The whole brand lives on the idea of effortlessness, wafting over the world, and the much-touted 'Magic Carpet Ride', and it really does deliver that sense of ease. You’re almost as relaxed at the wheel as you are in the rear seat (and the massage functions only make you feel more so). 

Speed humps do upset the Cullinan, but only a very little, and you’re aware when the car finds broken surfaces, but only distantly so. It feels like someone is dealing with bumps and imperfections in a far-off-place, perhaps the car’s basement, and it shouldn’t worry you too much.

When traffic annoys you, you can just make it disappear by engaging your whumping V12 engine and making the world go briefly blurry. 

Attempt to throw the Cullinan through sharp bends at speed, however, and it reacts in much the same way you’d expect the cruise ship it somewhat resembles to.

There’s a bit of body roll, but it’s all quite polite and a sense that if you need to drive like that, perhaps you should go and get one of your other cars.

The Black Badge version does feel just a trifle sportier than the base Cullinan but we’re splitting very grey and expensively coiffed hairs here.

The overall experience is one of grand relaxation, imperiousness and a certain touch of superior glee.

The Rolls-Royce Cullinan SUV has not been ANCAP tested, but it feels safe because it’s bigger than a tank. It has eight airbags - driver, front passenger, two curtains, driver side, front passenger side, two rear passenger side), and a full-suite of active-safety tech including Forward Collision Warning and Automatic Emergency Braking. 

The Mercedes EQS450 is covered by Mercedes-Benz's five-year, unlimited-kilometre warranty, with servicing required every 12 months or 25,000km.

You can prepay your service costs, coming in at $2350 for three years, $3695 for four years or $4280 for five years.

The battery its covered for eight years or 160,000km.

Questions about service intervals and warranties seem to confuse the people at Rolls, as if none of their customers have ever bothered to ask.

Yes, you would think servicing would be free when you’re pushing a $1 million price tag, and that the warranty would be for life, particularly considering the low mileage on these things, but it is, in fact, just a four-year servicing and warranty offer for Australian customers of this vehicle. So that means an unlimited-mileage warranty, including all services, for the first four years (at which point you obviously buy a new one). "Rolls-Royce Motor Cars will offer a service inclusive package but no pricing available yet and this will not be required until the fifth year of ownership."
