From Rolls-Royce press: The new Phantom with extended wheelbase offers additional interior space for 
the rear occupants while maintaining the elegant exterior looks of the standard 
length Phantom and its first class driving performance.

An extra 250mm has been added to the standard Phantom, behind the B-pillar, to 
create a car with an even more generously proportioned rear passenger 
compartment. The extra space lends itself perfectly to the addition of Bespoke 
features, limited only by the imagination of the customer.

An extended wheelbase car had been planned from the early days of the 
Rolls-Royce Phantom project. An aluminium space frame chassis was chosen for 
the Phantom precisely because it lends itself to structural adaptation with 
relative ease. This ability to create Bespoke models to meet the individual 
needs and desires of Rolls-Royce customers is something that has been central 
to the marque throughout its 100-year history.

The extra length is achieved simply by using longer extrusions in the 
construction of the body without any loss in torsional rigidity. The 
outstanding dynamic performance and driving refinement of the Phantom is 
maintained. Aluminium roof and rear door panels are the only new major exterior 
parts required.
