2024 Audi RS6 vs 2021 Rolls-Royce Ghost

What's the difference?

To me at least, the RS6 is pretty much the ultimate fast and practical car. One which is just as comfortable plodding around town as it is tearing it up on the track. Keep in mind, too, this may be one of your last chances to have a car which looks like this, equipped with a V8 engine. So, have I convinced you? Would you consider one of these over a performance SUV? Tell us what you think in the comments below.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

You might see it as an obscene indulgence or a piece of engineering excellence, but there’s no denying the new Rolls-Royce Ghost is exceptional. Incredibly refined and capable, it’s arguably the most impressive ‘entry-level’ car in the world. 

At a distance the RS6 is just an unassuming station wagon, but the closer you get, the more apparent it becomes how mean it is. It’s wide, it’s chiselled, it’s not just good looking, it’s iconically Audi.

The stance is so wide, its ride height so low, and its wheels are so massive that any keen eye will be able to spot where the difference is between this and any old family hauler.

Wagons may not be trendy, but there’s something undeniably cool about having the hauling capacity of an SUV at the ride height of a sedan.

Of course, if you want to look even more svelte and don’t need the boot space, the RS7 is always lurking around at a slight price premium.

Inside, the RS6 has all the modern amenities of the Audi range. Expect the usual sharp screens, lovely sports seats, and a tasteful application of textures throughout.

There’s a blend of carbon-look finishes, chrome, leather and gloss black. Perhaps a little too much gloss black to keep clean, but the aesthetic is suitably upmarket. 

You can go to town on customisation, and the car we primarily tested had stitching and colour in the carbon patterns to match its 'Ascari Blue' exterior, but you can pick whatever shade or combination of colours your budget allows.

Audi’s software is pretty good these days, with an attractive theme and fast hardware to back it, and the brand’s ‘Virtual Cockpit’ is still one of the most aesthetically pleasing and customisable digital instrument systems on the market, despite being one of the first.

Rolls-Royce adopted what it calls a ‘post-opulent’ philosophy in development of the new Ghost’s design. Specifically, restraint, “rejecting superficial expressions of wealth.”

That’s because, as a rule, Ghost customers aren’t Phantom customers. They don’t want to make that big a statement, and prefer to drive the car as much as they might be chauffeured in it.

This Ghost is longer (+89mm) and wider (+30mm) than the outgoing model, yet it’s a superbly balanced shape, with minimalism the guiding design principle. 

That said, the iconic ‘Pantheon Grille’ is bigger, and now downlit by 20 LEDs under the top of the radiator, with its individual slats polished even more carefully to subtly reflect the light. 

The car’s broad surfaces are tightly wrapped and deceptively simple. For example, the rear guards, C-pillars and roof are fabricated as one panel, which makes sense of the absence of shutlines around the rear of the car (except for the boot outline, of course).

Rolls-Royce refers to the Ghost’s cabin as an ‘interior suite’ consisting of no less than 338 individual panels. But despite that number, the feeling inside is simple and serene.

In fact, Rolls says its acoustic engineers are experts in serenity. Sounds like Darryl Kerrigan needs a Ghost for the family road trip to Bonnie Doon.

A few details stand out. The open pore wood trim is a welcome, tactile change from highly finished veneers that often do their best to look like plastic.

The proper metal chromed trim elements around the cabin confidently say quality and solidity, and the steering wheel, as well as the buttons around the multimedia controllers are subtle throwbacks.

The wheel has a circular central pad, with ancillary buttons around its lower perimeter, which echoes the style of the 1920s and ‘30s. You half expect an ignition advance/retard lever to sprout from its centre.

And the buttons around the media controllers use a combination of shape, colour and typeface to conjure up thoughts of the same era. They could be made of Bakelite.

For those that way inclined, the signature ‘Starlight Headliner’, using untold LEDS to create a glittering night sky in the roof, now incorporates a shooting star effect. You can even option up the constellation of your choice.

Okay, I promised a car with the practicality of an equivalent SUV, but it’s not quite there. The trade-off is still worth it, I promise, but there are a few areas where the RS6 isn’t as practical as you think it’s going to be, particularly for front occupants.

Yes, it’s a big wide car, with large but supportive seats and plenty of headroom, but the issue for those travelling in the front two seats is the surprisingly limited amount of storage.

Yes, there are two bottle holders in the centre console with a folding tray lid to hide them away, but they aren’t huge. Bigger bottles would have to go in the door bins, but even then they’re a bit height-constrained.

There’s a decent glove box on the passenger side, but even the centre console box is very shallow, with more than half of it taken up by a wireless phone charger.

The touch panel for the climate unit looks impressive but still can’t match having physical dials. It has clicky haptic feedback to your individual presses, and all the functions are permanently accessible instead of hidden in sub-menus, so if you’re going to make climate a touch-based interface, it doesn’t get much better than this.

Where the RS6 shines is in the back seat. Despite those big bucket front seats, I had heaps of room behind my own seating position (at 182cm tall), with lots of headroom and sufficient width in the cabin to spread out.

You sink into the rear seats, which are heavily contoured so riding in the back is a pretty good experience even on the track.

Rear passengers get four adjustable air vents in both the B pillars and in the centre, as well as their own touch panel for the rear climate zone.

USB power outlets are also available, and there are netted pockets on the front of both back seats, with a further two bottle holders in the drop-down armrest.

The centre seat is probably only good for kids, because there’s a very tall raise in the centre required for the driveshaft, eating all the legroom.

The boot is fairly large at 548 litres which is in mid-size SUV territory, although I will admit some performance SUV rivals offer closer to 600L.

Space expands to 1658L with the second row folded flat.

The new Rolls-Royce Ghost is over 5.5m long, more than 2.1m wide, and close to 1.6m tall. And within that substantial footprint sits a 3295mm wheelbase, so no surprise utility and practicality are exceptional.

First, there’s getting in. The ‘coach’ or ‘clamshell’ doors will be familiar to current Ghost owners, but their “effortless” operation is new, a gentle pull on the door handle bringing welcome electronic assistance.

Once inside the rear of the car, as on the previous model, the press of a C-pillar-mounted button will close the door.   

But up front, easing onto the generous driver’s seat is a breeze thanks to the Ghost’s sheer scale and a large door aperture. 

There’s plenty of space for people and things in a thoroughly considered layout. A large glove box, big centre storage box (containing every connectivity option known to humankind) a lined slot for your phone and twin cupholders under a sliding timber cover. The door pockets are generous, with a sculpted section for bottles. 

Then the rear. Obviously designed for two, the back seat will seat three. The sumptuous full-leather seats are multi-way electronically-adjustable, and NBA players (almost certainly prospective owners) will be happy with the leg, head and shoulder room provided.

Need even more room in the back? Step this way to the ‘Extended’ long-wheelbase version of the Ghost, measuring 5716mm long (+170mm), with a 3465mm wheelbase (+170mm), and stepping up in price to $740,000 (+$112,000). That’s $659 per additional millimetre, but who’s counting?

But back to the rear of the standard wheelbase car. Fold the large centre armrest down and twin cupholders pop out the front. Then, a wood-trimmed lid on the top flips forward to reveal a rotary multimedia controller.

Behind that, a beautifully trimmed storage box offers generous space and 12V power, and behind door number three (a pull-down leather panel in the back of the armrest aperture) is a small fridge. What else?

The rear of the front centre console houses individual climate-control outlets as well as USB and HDMI sockets.

Touch a discreet chrome button and small desks (RR calls them picnic tables) fold down from the front seat backs, faced in the same open pore wood as the dash, console, steering wheel, and door trims, and finished off with flawless chrome.

The entire interior benefits from a ‘Micro-Environment Purification System’ (MEPS), and rather than bore you with the details, let’s just say it’s exceptionally efficient. 

Boot volume is a solid 500 litres, with an electrically-assisted lid and plush carpet lining. Of course, the air suspension system can lower the car to make loading heavy or awkward objects that little bit easier.

Good value is open to broad interpretation in this rarefied part of the new car market. On the surface, value could relate to standard equipment; the features that make life with a car safer, more comfortable, and efficient.

It might also have you lining up the competitors, to determine how much sheet metal, rubber and glass you’re getting for your money. Maybe a Mercedes-Maybach S-Class, or Bentley Flying Spur?

But peel away those layers and you’re getting closer to the heart of the Rolls-Royce value equation. 

A Rolls-Royce is a statement of wealth, confirmation of status, and indicator of success. And that will be enough for some. But it also delivers value to those who appreciate the last few percentage points of creativity and effort that deliver exceptional results.

Sounds like a bit of a gush. But once you dip into the background of this car’s development and experience it first-hand, it’s hard not to.

We could produce a separate story on the Ghost’s standard features, but here’s the highlights reel. Included are: LED and laser headlights, 21-inch twin-spoke (part-polished) alloy wheels, electrically-adjustable, ventilated and massaging seats (front and rear), an 18-speaker audio system, electrically-assisted ‘Effortless Doors’, a head-up display, full leather trim (it’s everywhere), multiple digital screens, active cruise control, adaptive air suspension, and there’s lots more.

But let’s pick a few of those out for closer inspection. The audio system is designed and produced in house, featuring a 1300W amp and 18-channels (one for each RR built speaker). 

In fact, there’s a team dedicated to audio performance, and it’s made the entire car an acoustic instrument, calibrating resonance through its structure to optimise clarity. Not the work of five minutes, requiring complex collaboration with the design and engineering teams, not to mention the bean counters.

And yes, there’s leather everywhere, but it’s of the highest quality, analysed to (literally) a granular level to ensure it makes the cut for use in this car. Even the stitching is set to a particular (longer than typical) length to minimise visual noise.

How about RR personnel travelling the globe to measure rain drops to make sure the roof rain channels perform as well as they can (true story). Or the 850 LED ‘stars’ in the dash fascia, backed by a 2.0mm thick ‘light guide’ with 90,000 laser-etched dots to disperse light evenly, yet add a twinkle.

You get the idea. And as much as they say, ‘If you have to ask the price, you can’t afford it’, the cost-of-entry for a 2021 Ghost, before any options or on-road costs, is $628,000.

Depending on your perspective, a stupendous sum that will buy 42.7 entry-level Kia Picantos, a car every bit as capable of transporting you from A to B as the Ghost. Or alternately, brilliant value, in that it buys the ultimate attention to detail applied to this car’s design, development and execution. You be the judge, but for what it’s worth, I’m in the latter camp.

The RS6 is still packing eight cylinders in 2023, producing a massive 463kW/850Nm, somehow an increase (+22kW/50Nm) over the previous iteration.

Audi’s signature ‘Quattro’ all-wheel drive system is present alongside a limited-slip differential and four-wheel steering.

Air suspension and performance brakes and exhaust also feature, alongside an aggressive Continental SportContact 7 tyre package.

The 0-100km/h sprint time is now just 3.4 seconds, allowing you to show up even some electric cars, and the RS6 features 48-volt mild hybrid technology with a cylinder-on-demand system which can shut half the block down for more efficient coasting.

The transmission is an eight-speed torque converter unit which is smooth and effortless.

The new Ghost is powered by an all-alloy, direct-injection, 6.75-litre, twin-turbo V12 (also used in the Cullinan SUV) producing 420kW (563hp) at 5000rpm, and 850Nm at 1600rpm.

The ‘six-and-three-quarter-litre’ V12 has a distant link to BMW’s ‘N74’ engine, but Rolls-Royce is at pains to point out this unit stands on its own two feet, and that every piece of it bears a RR part number. 

It runs a Ghost-specific engine map, and permanently drives all four wheels through a GPS-guided eight-speed automatic transmission.

That’s right, the GPS link will pre-select the most appropriate gear for upcoming bends and terrain with the aim of producing “a sense of one endless gear.” More on that later.

Officially, the RS6 and its eight cylinders drink a combined 11.8L/100km, although even with its fancy hybrid system and cylinder deactivation, my time with the car saw 15.0L/100km. The RS6 has a 72-litre fuel tank and takes only the finest 98RON unleaded fuel.

Rolls is currently quoting European Regulation (NEDC) fuel consumption numbers for the new Ghost, which for the combined (urban/extra-urban) cycle is 15.0L/100km, the big V12 emitting 343g/km of CO2 in the process.

On the launch drive, covering around 100km of urban pottering, B-road cornering, and freeway cruising, we saw a dash-indicated figure of 18.4L/100km. 

Premium 95 RON unleaded fuel is recommended, but if circumstances (presumably in the back-of-beyond) demand it, standard 91 unleaded is usable. 

Whichever you choose, you’ll need no less than 82 litres of it to fill the tank, at our average fuel use, enough for a theoretical range of 445km.

As you might have guessed from its impressive engine and performance equipment, the RS6 is a certified weapon on road and track.

On the road you can expect a quiet, refined cabin, superbly balanced steering for low and high speeds and a gentle ride quality courtesy of the pricey air set-up.

It’s as noisy or as quiet as you want it to be, with the cylinder deactivation toning things down at low speeds, and the engine roaring to life under heavy acceleration, or when the 'Dynamic' drive mode is selected.

It can at times be alarming how much the RS6 leaps to life, as it feels so cushy in a city, its width and cabin giving the feel of a luxury car rather than a performance one.

Make no mistake, though, the RS6 is properly quick, and when you give it a kick, it’s the roaring, aggressive machine the spec sheet suggests.

The best place for this? The track, of course. The big V8 and the capability of the all-wheel drive system are truly best explored at velocities impossible to legally achieve on the road.

Once you get past the bark and snarl of this wagon’s eight-cylinders at full force, and the lightning-fast shifts of its eight-speed automatic, you’ll have a moment to appreciate the way it simply holds to the tarmac when you tilt it into the corners, providing a balance when loaded up which only air suspension can provide.

The steering is awesome, communicating the texture of the road nicely to the driver, and requiring just the right amount of force to keep the car pointing where it needs to go.

The grip level is astounding with the huge tyres and the four-wheel steer system lets this hefty wagon take corners at a tighter angle than your brain initially allows.

Thankfully, the four-wheel steer system isn’t weird, either. While it can have a strange effect on some cars, in the RS6 it only bends your mind slightly when you tip it into a hairpin. Otherwise it feels pretty normal.

When everything is warmed up, it can let its guard down slightly and allows the driver to eke out a slide at the rear here and there for extra fun-factor

Jeez. What a machine. I guess this is what a quarter of a million dollars buys. A car that can do it all. Take the kids to the school in comfort and tear it up on the track like few other passenger cars on the same day.

There’s a caveat, though. A small one which looks like it will turn into a big one for cars like this in the near future.

I had the opportunity to drive the RS e-tron GT around the same circuit and it was better. Much better.

It was faster, more accurate, more composed. It was so effortless, I didn’t realise exactly how much quicker than the RS6 it was until I drove them back-to-back.

It’s a good sign for the future, but also a reminder a V8 like this isn’t the performance pinnacle it once was.

So, if this Rolls is designed to be driven, what’s it like behind the wheel? Well for a start, it’s plush. As in, the front seats are big and comfortable, but surprisingly supportive and endlessly adjustable.

The digital instrument cluster tips its hat to classic RR dials, and despite thick pillars (especially the bulky B-pillars) vision all around is good.

And if you’re thinking 2553kg is a lot of Ghost to get moving, you’re right. But there’s nothing like applying 420kW/850Nm of twin-turbo V12 muscle to the task.

Peak torque is available from just 1600rpm (600rpm above idle) and Rolls-Royce claims 0-100km/h in 4.8sec. Plant the right foot and this car will calmly have you at throw-away-the-key speeds in the blink of an eye, the eight-speed auto shifting imperceptibly all the way. And even at full throttle, engine noise is relatively subtle.

But aside from that prodigious thrust, the next eye-opener is unbelievable ride quality. Rolls calls it ‘Magic Carpet Ride’, and it’s no exaggeration.

The bumpy road surface disappearing under the front wheels just doesn’t compute with the unruffled, perfectly smooth progress you’re experiencing. It is unbelievable.

I’ve only had that sensation once before, behind the wheel of a Bentley Mulsanne, but this was possibly even more surreal.

Rolls-Royce’s ‘Planar’ suspension system refers to, “a geometric plane which is completely flat and level”, and it works.

The set-up is double wishbones at the front (incorporating a unique to RR upper wishbone damper) and a five-link arrangement at the rear. But it’s the air suspension and active damping that create the magic Rolls calls “flight on land.”

A ‘Flagbearer’ stereo camera system in the windscreen reads the road ahead to proactively adjust the suspension up to 100km/h. It’s name recalls the early days of ‘motoring’ where a person waving a red flag walked in front of cars to warn unwary pedestrians. This slightly more sophisticated approach is just as arresting.

This time around the Ghost is all-wheel drive (rather than RWD) and it puts its power down brilliantly well. We dared to push it fairly aggressively on a twisting B-road section and all four fat Pirelli P Zero tyres (255/40 x 21) kept things on track without so much as a squeal.

A 50/50 weight distribution and the stiffness of the car’s aluminium space-frame architecture help keep it balanced, planted and under control. But on the flip side, steering feel is almost completely MIA. Numb and overly light, it’s the missing link in the Ghost’s otherwise impressive dynamic performance.

Drop into a freeway cruise and you become aware of the impossibly low noise level. But it’s not as quiet as it could be. Rolls says it’s able to achieve near silence, but adds that becomes disorienting, so it introduced an ambient “whisper”... “a single, subtle note.” 

To achieve this level of calm the bulkhead and floor have been double-skinned, interior components are tuned to a specific resonance frequency, and there’s 100kg worth of acoustic damping materials within nearly half the architecture of the car, in the doors, roof, double-glazed windows, even inside the tyres.

The four-wheel steering system helps with agility on the highway (where the front and rear axles steer in unison), but comes into its own at parking speeds (where they counter-steer), because even with numerous cameras and sensors, parking this 5.5m long, 2.5-tonne machine is quite an undertaking. Turning circle is still 13.0m, though, so beware. If all else fails, the car will park itself, anyway.

Beefy ventilated disc brakes front and rear wash off speed progressively and without a hint of drama.

Other highlights? The multimedia system is the only thing openly borrowed from BMW, but that’s not a problem because the interface is great. And that 1300W, 18-speaker 18-channel audio system absolutely cranks!

Rolls-Royce doesn’t submit its cars for independent safety assessment, so no ANCAP rating for the new Ghost, unless, of course, the local testing authority chooses to purchase one. Enough said...

The previous Ghost was limited by its ageing 7 Series platform when it came to the latest active safety tech, But this version, sitting on a bespoke RR chassis, brings the entry-point Roller up to speed.

Included are AEB, incorporating ‘Vision Assist’ (day and night wildlife and pedestrian detection), active cruise control (with semi-autonomous driving mode), cross-traffic warning, lane-departure and lane-change warning, as well as an ‘Alertness Assistant.’

There’s also a four-camera system with panoramic and helicopter view, as well as a self-park function, and a hi-res head-up display 

If all that’s not enough to avoid an impact, passive safety includes eight airbags (front, front side, full-length curtain, and front knee).

There are also top tethers and ISOFIX anchors on the two outer rear seat positions for safely securing child restraints for kids fortunate enough to be travelling in this kind of style. 

Five years and unlimited kilometres is the warranty length, and Audi’s ownership program includes invites to events like the one we were able to experience for the launch of this car. A track-test of the RS6 and the RS e-tron GT.

If you own one, I recommend them, you’ll learn a thing or two about the car and possibly yourself while you’re at it.

Servicing is required once every 12 months or 15,000km, and a service pack covering the first five years or 75,000km can be purchased alongside the car at a cost of $4360.

It works out at $872 per year, which isn't economy car cheap, but with such a complex drivetrain, what did you expect?

Rolls-Royce covers its Australian range with a four year/unlimited km warranty, but that's just the tip of the ownership iceberg.

The mysterious ‘Whispers’ owners portal, a “world beyond”, is claimed to offer the opportunity, “to gain access to the inaccessible, to discover rare finds, to connect with like-minds.” 

Plug your car’s VIN into the app and you’ll be on the receiving end of curated content, event invitations, news and offers, as well as access to your own ‘Rolls-Royce garage’, plus a 24/7 concierge. All complimentary.

What’s more, service is recommended every 12 months/15,000km, and it’s free-of-charge for the duration of the warranty.
