Inspiration for the roof opening comes from what EDAG considers an oversight by Rolls-Royce. In factory models the C-pillar was purposely created extra large so rear passengers would have the sense of additional privacy and security. This however results in a rather difficult entry and exit from the vehicle, even for people of average height.
To correct this problem EDAG had to use carbon fiber reinforcements in the roof and modify the interior ceiling with original components from Rolls-Royce to create a seamless appearance. To open the roof panel the driver or passenger simply presses a button, and then the hydraulically powered roof segment will rise in a smooth silent motion.

The vision of comfort
Besides developments aimed at improving their ecological compatibility, the question of comfort will be a decisive factor in the marketing success of future vehicle types. Having said this, in the age of networked communication and infotainment systems, the term "comfort" is not limited purely to
physical comfort in the car. A car of tomorrow will have to provide the customer with the ability to access any data and information which he or she needs for either private or professional use. Merging the realms of vehicle, office, home and worldwide service and infotainment options defines the future meaning of the word comfort in the automotive branch.
As a global partner to the automotive industry, EDAG has defined "the vision of comfort" as its leading theme, and this will take centre stage at the company's presentation at the 2008 Geneva Show. With its presentation of the articulated roof for the Rolls Royce Phantom, EDAG is showcasing its first step towards its target of developing complex, innovative luxury solutions.
"Vision of Comfort" – Focus: Vehicle Body
Innovative vehicle body concepts in the exterior and interior will also contribute to an increase in com-fort within the car in the future. Ergonomically optimised package concepts, such as access aids, serve to improve convenience considerably. Controls, seating comfort, air conditioning and visibility all have to undergo constant refinement, as requirements are always changing. This will mean that vehicle derivatives, created by designers and engineers to have optimised functions and guarantee user convenience, will become an absolute must.
Using the example of one means of optimising access to a Rolls Royce Phantom, EDAG will be documenting its expertise in the development and close-to-production implementation of innovative luxury concepts within the field of vehicle bodies.
Optimised entry to a Rolls Royce Phantom
Not even a Rolls Royce Phantom will be able to satisfy its owner’s every wish. One example is the seat behind the ‘C’ pillar in the rear of the car, which traditionally creates a feeling of security and privacy.
With the production model, however, this does have a price: namely the fact that it is impossible, even for someone of average height, to enter and leave the car in an upright position. The solution that EDAG developed is an articulated roof over the rear seat area, so that passengers can get into and out of the car in comfort.
It might sound trivial, but the job called for a great deal of technical finesse. First of all, EDAG’s Product Development and Production departments worked out various concepts for raising the roof and the lateral roof frame together. It goes without saying that the exclusive interior design was to be borne in mind at all times, and that neither rigidity, comfort nor sealing capacity were to be compromised under any circumstances whatsoever.
There was no way to avoid severing the lateral roof frame of the aluminium spaceframe. A reinforcement cut from solid metal, which at one and the same time incorporates the kinematics, water channel, locking mechanisms, seals and finger protection, does, however, provide the essential rigidity of the body.
The aluminium structure for the roof was likewise cut from the solid. To save weight, the roof’s outer skin panel is made of synthetic carbon-fibre material. The roof’s interior trims were re-designed, and covered with original quality Rolls Royce materials. By simply pressing a button, the driver or passenger can activate the specially developed electronic controls, and raise the hydraulically powered roof segment with practically no sound whatsoever. Modification of the roof structure has had no effect on either the car's handling or its interior acoustics.
