THE NEW ROLLS-ROYCE GHOST…

Client feedback asking for near-instant torque and near-silent running led the marque to further develop the Rolls-Royce 6.75-litre twin-turbocharged V12 petrol engine. A bespoke Ghost engine map was created to ensure ample performance for this dynamic motor car, delivering 563bhp/420kW and 850Nm/627lb ft of torque to the all-wheel steer, all-wheel drivetrain. Commensurate with clients’ expectations, maximum torque is available from just 1600rpm – only 600rpm above tick-over. To further refine its already remarkable acoustic properties, the air intake system incorporated larger porting to reduce engine presence in the interior suite. The marque’s hallmark Magic Carpet Ride has evolved. For new Ghost, engineering specialists redesigned the motor car’s suspension completely to deliver what is called the Planar Suspension System. Named after a geometric plane, which is completely flat and level, the system is the result of ten collective years of testing and development to create a sense of flight on land never before achieved by a motor car. Created through physical engineering developments as well as sophisticated scanning and software technology, it incorporates a world-first Upper Wishbone Damper unit above the front suspension assembly, creating an even more stable and effortless ride. This works alongside the Flagbearer system, which uses cameras to read the road ahead and prepare the suspension system for any changes in road surface, as well as the marque’s Satellite Aided Transmission. These technologies are managed as one through a bespoke Planar software system. New Ghost can now anticipate and react to the most demanding road surfaces. The Upper Wishbone Damper alone was the result of five collective years of road and bench testing. Reserved exclusively for Rolls-Royce, this technology further evolves the marque’s double-wishbone Magic Carpet Ride suspension system. The ethos of the marque’s founder, Sir Henry Royce, was “Take the best that exists and make it better,” and in this spirit chassis specialists developed the Upper Wishbone Damper to further improve the continuously variable, electronically controlled shock absorbers and the self-levelling high-volume air strut assembles. It has never before been applied to a production motor car. The five-link rear axle benefits from the same self-levelling high-volume air suspension technology, as well as rear-wheel steering. Both axles are managed via the marque’s Planar software. This also governs new Ghost’s other chassis technologies, including the all-wheel drive, all-wheel steering, stability control and self-drying braking systems, to ensure the motor car is reacting as one to changes in surfaces or grip levels while also maintaining a spirited, dynamic personality. The Planar software also manages information that requires new Ghost to proactively adapt to intrusions in the road ahead. The first of these technologies is the marque’s Flagbearer system. Evocative of the men who were required by law to carry a red flag ahead of early motor cars, this technology consists of a stereo camera system integrated in the windscreen to see the road ahead, adjusting suspension proactively rather than reactively up to 100km/h. The second is Rolls-Royce’s Satellite Aided Transmission system, which draws GPS data to pre-select the optimum gear for upcoming corners. The result is unprecedented levels of ride comfort and control for a motor car. Rolls-Royce clients have enjoyed self-closing doors since the first Goodwood Phantom. Operated by a button on the dashboard and on the C-pillar for motor cars with rear doors, this innovation has been celebrated among customers. For new Ghost, the marque’s engineers elected to further develop this hallmark technology and, for the first time, clients can now also open the doors with power assistance. Clients first open the door with one pull of the interior handle, then allow the handle to return to its resting position while they check for potential hazards, and then pull and hold it for full power assistance on opening. Once the door is opened sufficiently for the client’s egress, they simply stop pulling the handle, which engages a door brake. Once the client has alighted, they are able to close the door completely automatically at the push of a button on the exterior door handle. If they prefer to close the door manually, the operation is power assisted. On-board longitudinal and transverse sensors, as well as G-force sensors fitted to each door, allow the same speed of operation regardless of hill or driveway angles.

New Ghost benefits from a new Micro-Environment Purification System (MEPS). Existing air filtration technology was further developed to incorporate a full suite of hardware and software improvements. Highly sensitive Impurity Detection Sensors were introduced to detect ambient air quality, automatically switching fresh air intakes to Recirculation Mode if unacceptable levels of airborne contaminants are present. This channels all cabin air through a nanofleece filter, which is capable of removing nearly all ultra-fine particles from the Rolls-Royce’s micro- environment in less than two minutes. New Ghost is perfect in its simplicity, but creating this pure and detoxifying environment was one of the greatest challenges in the marque’s history. Indeed, new Ghost is the most technologically advanced motor car Rolls-Royce has ever produced. Further equipment includes: LED and laser headlights with more than 600m of illuminated range, vision assist, including day- and night-time wildlife and pedestrian warning; alertness assistant; a four-camera system with panoramic view, all-round visibility and helicopter view; active cruise control; collision warning; cross-traffic warning; lane departure and lane change warning; an industry-leading 7×3 high-resolution head-up display; Wi-Fi hotspot; self-park; and the very latest navigation and entertainment systems. Ghost clients operate in complicated business worlds. From the moment they step into the interior suite of their Rolls-Royce, it is essential that they are imbued with a sense of wellness. Visually, this is the result of an obsessive approach to reduction and unwavering dedication to material quality and substance. Experientially, however, this is achieved through peerless chassis and drivetrain engineering, as well as an unrelenting approach to creating a serene acoustic ambience within the interior suite. Rolls-Royce acoustic engineers are experts in serenity. For new Ghost, it was decided that this expertise would be formalised and the marque’s specialists would create a Formula for Serenity that could help inform future products. The first element of this formula is the Rolls-Royce spaceframe architecture. Its aluminium construction has a higher acoustic impedance compared to steel. Additionally, it is constructed from complex forms, rather than flat, resonant surfaces. Both the bulkhead and floor sections are also double-skinned, sandwiching composite damping felts to reduce road noise intruding into the passenger suite. Larger sections of the architecture have also been created with specific access points for the installation of acoustic damping materials – new Ghost uses more than 100kg in total, applied in the doors, roof, between the double-glazed windows, inside the tyres and within nearly all of the architecture itself. The final element of the formula is harmonising the car. The marque’s acoustic specialists experimented with a completely silent interior suite, but found the experience to be disorientating. To overcome this, they elected to create a ‘whisper’, a soft undertone that is experienced as a single, subtle note.
