Now you can enjoy the Ghost’s interior without worrying about outside noise ruining your mood

LISTEN 04:54

The next-generation Rolls-Royce Ghost is scheduled to arrive later this year, and Rolls-Royce is pulling out all the stops to ensure that it lives up to all the hype of being a completely new model from the ground up.

Part of that challenge involves creating new features to improve the ownership experience of the Ghost, including ensuring complete serenity in the luxury ride’s interior. On that end, Rolls-Royce is fitting more than 220 pounds (100 kilos) of sound-absorbing materials throughout the body of the all-new Ghost.

What’s so important about a soundproof interior?

Soundproofing reduces the transmission of unwanted direct sound waves to an involuntary listener. If you’re sitting inside your car — and your car happens to be a Rolls-Royce Ghost — you’re going to want to bask in the serenity and tranquility of that cabin. Soundproofing the interior goes a long way in creating the kind of cabin tranquility that Rolls-Royce owners look for. These owners don’t spend more than $300,000 to buy a Ghost for nothing.

How did Rolls-Royce address sound-proofing the all-new Ghost?

Soundproofing a car as big and as sophisticated as the Rolls-Royce Ghost can be a complicated task. You don’t just plug the open spaces in the vehicle and call it a day. Rolls-Royce’s promise to create the next-generation Ghost from the ground up contributed to this task, in large part due to the all-new proprietary aluminum-rich architecture that already helps a great deal in absorbing outside noise.

From there, Rolls-Royce’s acoustics team — yes, it has an acoustics team — installed a double-skinned bulkhead section to separate the Ghost’s 6.75-liter V-12 engine’s compartment from the interior.

This also goes a long way in minimizing the amount of engine noise that reaches the interior. Cavities in the roof, doors, trunk, and floor of the Ghost were also plugged using more than 220 pounds (100 kilos) of sound-absorbing materials. Even the Ghost’s double-glazed windows were fitted with a clear composite center sheet while the luxury sedan’s tires were lined with lightweight acoustic insulation foam.

While the extra weight may compromise the Ghost’s performance capabilities, it also shows how far Rolls-Royce will go to achieve its goal in the name of customer satisfaction. The goal, after all, is to create a sound-proof cabin that Ghost owners can relax in without worrying about unnecessary outside noise disrupting their proverbial “me-time.”

So the Rolls-Royce’s interior is completely sound-proof?

Not necessarily. During the early part of testing, the acoustics team discovered that while removing all noise coming into the interior was the intended goal, it also had its drawbacks, specifically the disorienting feeling of essentially sitting in a vacuum.

To prevent that from happening, the team created what it calls a “whisper,” described as a soft undertone that Ghost owners experience as a single, subtle note.

Acoustically tuned damping units for the seat frames were created and a suite of ports was placed between the cabin and the Ghost’s trunk to ensure that the low and resonant frequency that Rolls-Royce created that’s consistent with Rolls-Royce’s new “whisper.”

What else do we know about the new Rolls-Royce Ghost?

Rolls-Royce has been tight-lipped about its development of the all-new Ghost. Fortunately, we have the benefit of spy shots of the new Ghost doing test runs on the road. At the very least, it gives us an idea of what the model is going to look like, swirly wraps and all.

From the looks of it, the Ghost’s signature large front grille remains in place, even if a lot of the design around has been updated. The hood, for example, looks smoother than the old model. The bumpers also look sportier, and while it’s hard to make out with all the wraps covering them, the headlights appear to be larger than they used to be. The rear-hinged back doors will also remain, though there are new brake lights on either side of the sedan’s rear section.

We didn’t get a good look at the interior of the test mule, but rest assured, it’s going to be tricked out in ways that only Rolls-Royce can pull off.

As for the engine, the next-generation Ghost will likely still use the same 6.75-liter twin-turbocharged V-12 engine that currently powers both the Phantom and the Cullinan.

An output of around 580 horsepower should be expected given that it’s replacing a model whose twin-turbo V-12 unit already produces 563 horsepower.

We know that even with the global coronavirus pandemic, Rolls-Royce remains keen on launching the all-new Ghost later this year. All shall be revealed then.

Rolls-Royce Cullinan specifications
Engine: 6.75-liter twin-turbo V-12 engine
Power: 563 horsepower
Torque: 627 pound-feet of torque
0 to 62 mph: 5.2 seconds
0 to 124 mph: 13 seconds (estimate)

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read full bio
About the author

When reviewing client feedback from the first Goodwood Ghost, it was clear that its cocooning, near-silent acoustic properties were of the utmost importance. These men and women operate in complicated business worlds and value the sense of calm and wellness that their Rolls-Royce creates. Therefore, in creating new Ghost, the marque’s team of acoustic specialists were obsessively focussed on this highly complicated engineering task.

To achieve a sense of absolute serenity, the acoustic team began by adapting the marque’s proprietary aluminium spaceframe architecture, which itself offers benefits owing to the metal’s higher acoustic impedance compared with steel and its construction from complex forms rather than flat, resonant surfaces. A double-skinned bulkhead section was selected to insulate the cabin from the already near-silent 6.75-litre V12 engine and cavities in the roof, boot and floor were created to fill with more than 100kg of sound-absorbing materials. Additionally, double-glazed windows with a clear composite centre sheet were used as well as tyres lined with lightweight acoustic insulation foam.

Once the sound stage was created, every component was obsessively interrogated for its acoustic properties. Those that produced unacceptable levels of noise were discarded and completely redesigned at the Home of Rolls-Royce in Goodwood, West Sussex, to better serve the client’s desire for serenity. Even the inside of the air conditioning ducts were smoothed to better insulate clients from intrusive noises.

However, upon early testing the acoustic team discovered that removing all noise was disorientating. Their solution was to create a ‘whisper’ – a soft undertone that clients experienced as a single, subtle note. To achieve this, each component had to be tuned to a specific resonant frequency. This task included the creation of acoustically tuned damping units for the seat frames, as well as a suite of ports between the cabin and the large 500-litre boot to ensure the low frequency it generated was consistent with new Ghost’s ‘note’.

The marque’s experts named this exhaustive process the Formula for Serenity. Following its creation, these specialists presented the acoustic advances they had made, showcasing how these remarkable developments would serve the demands of new Ghost clients. Rolls-Royce has elected to share elements of these internal briefings to demonstrate the engineering substance that underpins this extraordinary new motor car ahead of its official unveiling in autumn this year.

New Ghost Acoustic Engineering Lead, Tom Davis-Reason, says, “The extraordinary acoustic quality of new Ghost is the result of significant engineering developments and fastidious attention to detail, but it really is underpinned by the marque’s proprietary aluminium architecture. There is simply no way we could have created such an acoustically refined environment using a steel platform.”

The marque chose the popular and aesthetically appealing medium of animated illustrations to convey these insights. Rendered first by renowned illustrator, Charlie Davis, they were animated to cohesively and beautifully represent these findings in a fashion that befits the highly progressive new Ghost.

In addition to these insights presented in animation form, a series of five podcasts have been launched that reveal more of the marque’s findings, as well as insights into the underlying material and engineering substance of new Ghost in long form. Hosted by Johanna Agerman Ross, Curator of Twentieth Century and Contemporary Furniture and Product Design at the Victoria & Albert Museum in London, the podcasts are available on Apple, Google, Spotify and Deezer.
