Rolls-Royce Ghost vs Audi S6

What's the difference?

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. 

We adore the new S6 sedan. It looks great, feels comfortable and goes like stink all at the same time. What’s not to like?

It also helps that it is relatively good value, safe and practical by large-sedan standards, so it’s a bit of a no-brainer.

But will buyers be quick to dismiss the new S6 sedan because it’s not a more practical SUV? Time will tell, but we hope not.

Does the new Audi S6 sedan represent the best mix of executive style and boy-racer performance? Tell us what you think in the comments below.

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.

To these eyes, the new S6 sedan is very attractive, albeit not outlandish, in keeping with its executive focus.

Up front, the subtly aggressive S body kit immediately comes into frame, with the bumper sporting sinister-looking side air intakes.

And, of course, there’s Audi’s signature Singleframe, which is not only large and in charge, but also finished in gloss-black, like many of the S6 sedan’s exterior design elements.

Below the heavily creased bonnet, the HD Matrix LED headlights look both angry and sophisticated, with their integrated LED daytime running lights (DRLs) providing a crisp signature.

Around the side, the S6 sedan goes about its business quietly, but its blistered wheelarches do add some bulk and help to accentuate its strong shoulder line.

And then there are the thick skirts and 21-inch alloy wheels (with a space-saver spare), which have a sporty twin five-spoke design. It’s all very classy.

Speaking of which, the rear end is arguably the S6 sedan’s best angle thanks to its wicked LED tail-lights, which have a segmented signature.

The chunky bumper below incorporates a diffuser element that houses the quad exhaust tailpipes, while a blink-and-you’ll-miss-it bootlid spoiler rounds out the look.

Inside, the S6 sedan is a technological tour de force, with 10.1- and 8.6-inch touchscreens dominating its centre stack. The former is responsible for most of Audi’s latest multimedia system’s functions, while the latter takes care of the climate controls.

This set-up works pretty well, although a few too many taps are required for certain functions, and then there’s the issue of the glass display coverings, which are absolute fingerprint magnets alongside the gloss-black accents used throughout.

That said, the 12.3-inch digital instrument cluster and windshield-projected head-up display on hand are brilliant. In fact, they set the standard for the entire industry thanks to their design and breadth of functionality.

The S6 sedan does, of course, feel a little bit more special than the regular A6 inside, with the obvious additions being the front sports seats, which are covered in supple Valcona leather alongside the armrests. They even have diamond-stitched inserts.

Then there’s the obligatory flat-bottom steering wheel (with paddle-shifters), which is trimmed in Nappa leather alongside the gear selector, upper dashboard, door shoulders and knee rests. Indeed, hard plastics are hard to find here.

Meanwhile, a black headliner adds to the sportiness alongside the black Alcantara door inserts, but the cabin is otherwise a familiar (read: classy) affair.

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.

Measuring 4954mm long, 1886mm wide and 1446mm tall, the new S6 sedan is a large sedan in every sense of the term, which is mostly good news when it comes to practicality.

Cargo capacity is decent, at 520L, but can be increased to an undisclosed amount with the 40/20/40 split-fold rear bench stowed.

Speaking of the boot, there are four tie-down points and a cargo net to help secure loose loads, while a bag hook and a side storage net are also on hand, alongside a 12V power outlet. Bulkier items will, however, be confronted by a decent load lip.

In-cabin storage options are numerous, but not all are effective. The glovebox is well-sized, while the driver-side cubby is surprisingly large, but the central bin is shallow, mostly taken up by the wireless smartphone charger, two USB-A ports and the SD and SIM card readers.

A pair of cupholders is located in the centre console, with a 12V power outlet found in between, while the front door bins can accommodate one regular bottle each, just like their rear counterparts.

In the second row, there’s a fold-down armrest with two more cupholders as well as a shallow storage tray, while cargo nets are affixed to the front seat backrests.

The rear bench is pretty comfortable, with four inches of legroom available behind my 184cm driving position alongside decent toe-room. Headroom is also good, with about two inches on offer.

That said, three adults sitting abreast won’t enjoy the experience, due to the large transmission tunnel, which makes for limited footwell space. At least they’ll have access to a couple of USB-A ports and a 12V power outlet, below the central air vents.

For reference, child seats can be fitted to the outboard seats via top-tether and ISOFIX anchorage points.

The new S6 large sedan is priced from $149,900 plus on-road costs and is far better value than before, even if it does command a $33,900 premium over the regular A6's flagship variant.

Compared to its predecessor, the new S6 sedan is $21,480 cheaper, while Audi Australia claims it has also added $20,000 worth of kit.

Standard equipment not already mentioned includes metallic paintwork (our test vehicle was finished in Tango Red), dusk-sensing lights, rain-sensing windshield wipers, soft-close doors, auto-folding side mirrors with heating, rear privacy glass and a hands-free power-operated bootlid.

Inside, satellite navigation with live traffic, Android Auto and wireless Apple CarPlay support, digital radio, a 705W Bang & Olufsen 3D sound system with 16 speakers, a panoramic sunroof, keyless entry and start, power-adjustable front seats with heating, a power-adjustable steering column, four-zone climate control, an auto-dimming rearview mirror and LED ambient lighting feature.

Of note, buyers can opt for the $7700 Dynamic Package that bundles in speed-sensitive electric power steering, a rear limited-slip differential and all-wheel steering. It was not fitted to our test vehicle.

In terms of rivals, the BMW M550i sedan is identically priced, while the Mercedes-AMG E53 sedan is much more expensive, at $173,800. The S6 sedan arguably has the former beat on value but loses the performance battle due to its 390kW/750Nm 4.4-litre twin-turbo V8.

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.

The new S6 sedan is powered by a hard-hitting 2.9-litre twin-turbo V6 petrol engine that produces a strong 331kW of power from 5700-6700rpm and a punchy 600Nm of torque from 1900-5000rpm.

Compared to its aforementioned predecessor, power is unchanged, while torque has increased by 50Nm.

This unit is mated to a 48V mild-hybrid system that includes a trick Electric-Powered Compressor (EPC), which helps to reduce its turbo lag.

A reliable eight-speed torque-converter automatic transmission is responsible for swapping gears, while drive is sent to all four wheels via Audi’s rear-biased quattro system.

This combination helps it sprint from a standstill to 100km/h in an impressive 4.5 seconds, while its top speed is electronically limited to 250km/h.

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.

The new S6 sedan’s fuel consumption on the combined-cycle test (ADR 81/02) is 8.4 litres per 100 kilometres, while claimed carbon dioxide emissions are 197 grams per kilometre. Both figures are pretty keen given the level of performance on offer.

Audi says the aforementioned 48V mild-hybrid system reduces fuel consumption by 0.4L/100km thanks to its coasting ability, which sees the engine turn off for up to 40 seconds between 55km/h and 160km/h. It also engages idle-stop from 22km/h.

In our real-world testing, we averaged 14.4L/100km over 100km of driving skewed towards country roads over city traffic, with limited highway time. It’s worth noting that my spirited driving inflated this result. That said, while its fuel consumption is not as bad as it appears, this is still a thirsty sedan.

For reference, the S6 sedan’s 73L fuel tank takes 98RON petrol at minimum.

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!

The S6 sedan has no right being this good in a straight line and around corners…

Much of its success is owed to the 2.9-litre twin-turbo V6, which is now one of my favourite engines being built today. Simply put, it absolutely hammers.

Punch the accelerator from a standing start and it doesn’t take long for 600Nm to be on tap all the way through, and just a little bit beyond, the mid-range.

Occupants are firmly pressed into their seats as the S6 sedan sprints towards the horizon with vigour. Soon enough, 331kW arrives and hangs around until just prior to the redline.

Needless to say, this acceleration is addictive, and the EPC deserves some of the credit, as it effectively mitigates any dreaded turbo lag and ensures the engine is always seemingly on boost.

But we also need to acknowledge the eight-speed torque-converter automatic, which is a real beauty. Gear changes are nice and smooth, which is great, but what’s even better is their relative quickness – dual-clutch transmissions be damned!

Of course, extra performance can be extracted by switching between the engine and transmissions’ settings but, rest assured, they both stand up, no matter what.

However, we’d suggest spending time in the former’s most aggressive setting, as it unleashes the sports exhaust system, which sounds unreal.

Upshift with intent and you’re met with a booming ‘brap’. Downshifts and the overrun will even gift you a series of pops. In fact, the S6 sedan soundtrack sounds strangely similar to that of the five-cylinder RS3, and we have absolutely no problem with that.

Better yet, the S6 sedan has an appetite for corners, with its neutral handling a standout, partly thanks to its hard-working rear-biased quattro all-wheel-drive system, which works in tandem with all the other electronics to ensure there is plenty of grip at any given time.

This controlled driving pleasure is enhanced by the electric power steering on hand, which has a variable ratio. At low speed, it’s nice and light, but those after more heft can always switch to another one of its settings, which become progressively heavier… arguably too heavy.

Feedback through the wheel is also good, while the steering itself is pretty direct, lending itself to sporty driving, which, of course, is half of the S6 sedan’s mantra.

Coming into corners, braking performance is solid, thanks to the massive 400mm front and 350mm rear discs with red callipers, so the driver is brimming with confidence at every turn, even though there’s an unladen weight (with 75kg driver and luggage) of 1985kg to manage.

But let’s not forget the S6 is an executive sedan, so it has to ride like one. Thankfully, it does. The independent five-link suspension has air springs and adaptive dampers, which serve up comfort in spades, especially at high speed.

Its firm tune does come into frame when travelling on unsealed or uneven roads, with this exacerbated by the large 21-inch alloy wheels, which have a penchant for catching sharp edges.

ANCAP awarded the A6 range (including S6) a maximum five-star safety rating in 2018.

Advanced driver-assist systems extend to autonomous emergency braking with pedestrian detection, lane-keep and steering assist, blind-spot monitoring, rear cross-traffic alert, adaptive cruise control with stop-and-go functionality, high-beam assist, driver attention alert, hill-start assist, tyre pressure monitoring, surround-view cameras and front and rear parking sensors. Yep, buyers aren’t left wanting here.

Other standard safety equipment includes six airbags (dual front, side and curtain), electronic stability and traction control systems, anti-skid brakes (ABS), brake assist and electronic brake-force distribution, among others.

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.

The S6 sedan comes with Audi Australia’s three-year/unlimited-kilometre warranty, which falls short of the premium market’s relatively new five-year standard that was set by Genesis and followed by Mercedes-Benz.

Three years of roadside assistance is also bundled in, although this term can be extended up to nine years if the vehicle is serviced at an authorised dealership, which is great.

Speaking of which, service intervals are every 12 months or 15,000km, whichever comes first. Capped-price servicing plans are available, costing $2350 for three years/45,000km or $4110 for five years/75,000km. They’re pricey, but you weren’t expecting the opposite.
