Rolls-Royce Cullinan vs Audi Q8 E-Tron

What's the difference?

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.

The Audi Q8 e-tron ushers in welcome improvements to an already likeable and capable large luxury SUV.

But it is also feeling dated compared to newer and fresher rivals like the BMW iX, isn’t as good to drive as the best, offers disappointing range for the size of the new battery, and prices are creeping up for what is essentially a half-decade-old EV.

The name change isn’t enough. What the Q8 e-tron really needs is a massive leap in its Vorsprung durch Technik in a rapidly evolving electrified landscape.

 Very good… but far from great.

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 Q8 e-tron looks smaller than it actually is, with the SUV wagon’s length/width/height/wheelbase numbers measuring in at 4915/1937/1633mm/2928mm, respectively.

The Sportback version is slightly lower at 1619mm.

You’ll need a keen eye to spot the difference between the old e-tron and new Q8 e-tron, with almost all of the visual changes reserved for the front end.

For starters, there’s a new, two-dimensional four-ring logo that looks larger and flatter than before, sitting within a sleeker and slimmer grille treatment that now takes in the restyled headlights. Along with the redesigned bumper, the effect serves to broaden the SUV’s stance.

The effect also suggests improved aerodynamics, aided by small air foils near the wheel arches and a fully-clad underbody section.  

Otherwise, aside from the odd inclusion of the make-model name on the B-pillar and minor trim updates out back, the Q8 e-tron keeps the same, contemporary appearance of its predecessor. Which is no bad thing. 

And there are even fewer changes inside.

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.

More than merely good enough.

Entry and egress are easy thanks to a lofty ride height and wide-opening doors. Once sat, you’ll discover Audi has not changed anything much inside compared to the old e-tron. Frankly, very little needed to.

You’ll still find a strikingly stylish and upmarket cabin offering sufficient space for five people, a commanding driving position, superbly supportive front seats that are a boon when long-distance driving, plenty of storage options, ample ventilation and suitably moody lighting.

While not the most modern dash on the market when contrasted to the vast ‘hyper’ screens of some rivals, the Q8 e-tron’s remains very architectural in appearance and presentation.

Trim and material quality are certainly up to brand expectations. Practicality remains a priority, with lots of storage areas within the dash, console and door cards.

There are no fewer than three screens – a 12.3-inch digital instrument cluster Audi calls 'Virtual Cockpit', a 10.1-inch central multimedia display with haptic feedback and an 8.6-inch unit for climate control.

While they may seem daunting at first, a little familiarisation means most users will find them easy to operate.

Kudos, too, to the super-clear markings in the instrumentation, as well as the very satisfying tactile sensations of using the quality switchgear and controls. Typical Audi thoroughness here.

The same applies to the Q8 e-tron’s roomy and pleasantly-presented back seat area, with intelligently designed seating offering a nicely angled backrest as well as supportive cushion.

Three people can fit across without too much pain, though two is better, as the folding centre armrest and other amenities like air vents and climate control systems can be better-accessed and enjoyed.

You can see, smell and feel where your money’s gone inside. This is a quiet, isolated and cocooning experience, whether cruising on the motorway or stuck in heavy urban traffic. As you’d expect from a luxury SUV.

About the only real jarring aspect are the $3500 virtual exterior mirrors, created to improve aero performance. Their door-mounted screens are set low, outside the natural visual eyeline of the driver, creating confusion and adding precious extra seconds of eyes not on the road ahead. They’re irritating to the point of frustration.

Otherwise, the Q8 e-tron gets the job done inside, with cargo capacity at a reasonable 569 litres in the SUV wagon and 528L in the Sportback. And there’s even a 62L tub in the frunk up front to store the cables that also come standard with the EV.

Audi interior and packaging expertise strikes again.

First thing’s first. The Q8 e-tron has very little in common with the existing Q8 petrol, diesel and SQ8 high-performance models.

These, along with the larger Q7, have internal combustion engines.

However, keep in mind all leverage variations of the same 'MLB Evo' architecture that first saw the light of day all the way back in 2015. So, no spring chickens here.

But as it currently also serves Bentley, Lamborghini and Porsche SUVs, we’re talking about a classy set of components, anyway. Plus, the pre-facelift model was only rolled out on the world market in 2019.

For now, only a single variant is here, known as the Q8 e-tron 55, meaning the previous, smaller-battery 50 and flagship SQ8 aren’t here yet. That will happen sometime during 2024.

As before, there’s the choice of a traditional SUV wagon or more-popular BMW X6-style Sportback SUV coupe.

Prices start at $153,900 (all prices are before on-road costs) for the former and $165,900 for the latter, and that’s a jump of nearly $8K and $9K respectively over their old e-tron-as-a-noun-rather-than-an-adjective predecessors.

At least the Q8 e-tron is well equipped.

On the safety front, you’ll find about 40 driver assistance systems, backed up by a plethora of cameras, radar sensors and ultrasonic sensors to help keep the SUV as secure as possible.

These include a 360-degree camera system, adaptive cruise control, lane-support systems, rear cross-traffic assist and Autonomous Emergency Braking (AEB).

More on safety further down below.

All models also include adaptive air suspension with a variable ride height range of 76mm, a drive-mode selector that switches between normal and sport settings, LED headlights with auto high beams, keyless entry/start, front and rear climate control, heated and powered front seats and adjustable regenerative braking paddles on the steering wheel.

There's also a head-up display, three digital screens including electronic instrumentation and a central touchscreen with haptic feedback, satellite navigation, Android Auto, wireless Apple CarPlay, digital radio, wireless smartphone charging, four USB-C ports, an electric tailgate with gesture control, roof rails and 20-inch alloy wheels – with a space-saver spare wheel to boot.

Plus, an undisclosed number of Launch Edition SUVs from $165,900 are also available, adding Audi’s S line exterior styling touches, 21-inch wheels, sports front seats, a racier steering wheel, electric steering column adjustment and more.

Note that the base Q8 e-tron 55 does not include leather upholstery (it’s synthetic material instead) or a sunroof as standard.

Pricing and spec, then, are generally in-line with the luxury Euro EV SUV competition, which is to say, a bit on the exxy side.

Let’s check out the changes.

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. 

Tech-overload alert. As per its predecessor, the Q8 e-tron 55 continues with two electric motors – one on each axle – for ‘quattro’ all-wheel drive.

Upgraded internals are said to improve efficiency substantially. Both are induction/asynchronous motors, mated to a single-gear two-stage ratio planetary transmission.

In the 55 model, the dual-motor set-up delivers a combined 300kW of power and 664Nm of torque, for a healthy 0-100km/h sprint-time of 5.6 seconds, on the way to a 200km/h top speed.

That’s impressive, given the lightest Q8 e-tron 55 tips the scales from 2595kg. That said, the Audi’s power-to-weight ratio is an equally strong 116kg/tonne.

Other updates include more direct steering, stiffer front suspension and retuned chassis controls.

Suspension is a five-link arrangement all-around, with adaptive air suspension featuring an electronically controlled with continuously variable adaptive damping system.

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 good news is that the lithium-ion battery pack size rises from 95kWh to 114kWh, and is accompanied by faster DC charging capability, due to a jump from 150kW to 170kW.

While far from the class best, this cuts down charging times by a considerable margin.

The claimed driving range is 454km, while average consumption is a disappointing 25.6kWh/100km. The Q8 e-tron’s trip computer during our run in it recorded a mid-to-high 20s readout, by the way.

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.

For decades, Audi used the advertising tagline ‘Vorsprung durch Technik’ – which means Progress through Technology in its native German – to highlight how advanced its vehicles are.

So, how has the Q8 e-tron advanced over its predecessor?

Right from the get-go, there’s so much to dig about the electric Audi SUV, especially if you’re new to luxury EVs.

To start with, it’s as quiet as you’d expect, even by luxury brand standards. As the Audi accelerates, the sense of momentum is somewhat masked by how refined and civilised your progress is.

Watch that, though. You could get a speeding fine more easily than you expect!

Anyway, with 664Nm of torque coming on instantly, there’s certainly no shortage of it, backed up by enough muscle for effortless and instantaneous overtaking. This sort of motoring can become highly addictive.

Similarly, a low centre of gravity, combined with a beautifully modulated electric power steering and the quattro AWD set-up, provides pleasing agility combined with reassuring roadholding. Even when you’re pressing on, the Q8 e-tron corners and grip with confidence and control.

So far, so good. Especially considering the air suspension is further cushioning your sense of speed, with excellent bump absorption for an isolated ride.

That’s on the standard 20-inch alloys spec. Riding on the larger wheels, there is a bit more firmness, as well as some road-noise intrusion.

Plus, it doesn’t take long to realise the Q8 e-tron is a very heavy vehicle. Though undeniably quick and athletic, changing directions in a hurry means that the SUV can feel a bit unwieldy.

Throttle response at higher velocities can seem a little muted and, over certain crests and humps when travelling fast, there is a sense that the driver really needs to have their wits about them.

Best to take it a bit easier, then, and enjoy the serenity the Audi EV SUV delivers in more typical and restrained travelling scenarios.

There is so much that the Q8 e-tron brings, and driving it normally really does reveal a sophisticated, comfortable, dependable and high-quality grand-touring experience.

Push a bit harder, though, and some cracks show up.

Tested way back in 2019 but updated in September, 2023, the e-tron/Q8 e-tron range scored a maximum five-star ANCAP crash-test rating.

There is no shortage of safety equipment – with passive and active, driver-assist-heavy technologies designed to avoid an accident, with full surround-view cameras also providing an extra level of security.

Standard kit includes Audi’s 'Pre-Sense front' and 'Pre-Sense rear', offering AEB, cross-traffic alert and active lane-keep assistance tech, as well as adaptive cruise control with full stop/go, eight airbags (dual front as well as side and curtain airbags for all outboard occupants), hill-descent control, anti-lock brakes, electronic brake-force distribution, brake-assist, electronic stability control, traction control and tyre pressure monitors.

The AEB system can detect pedestrians and cyclists between 10km/h and 85km/h, and even at night, while for other motor vehicles that increases to 250km/h (an upper velocity more relevant for the coming SQ8 e-tron). The active lane warning operations is from 65-250km/h.

Both outboard rear seats feature ISOFIX child-seat latches, along with three top tethers for straps.

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."

Audi provides a five-year/unlimited kilometre warranty as well as six-years’ worth of free roadside assistance, which is nothing unusual these days, while the battery warranty is eight years or 160,000km.

The first six years of scheduled servicing is free, too. Intervals are every two years/30,000km (whichever comes first).

Plus, owners also receive six years of complimentary access to Chargefox’s network.
