Here is an open letter from Rolls-Royce confirming announcing the addition of a SUV or 4x4 vehicle.
"Today we confirm that we are developing an all-new Rolls-Royce with exceptional presence, elegance and purpose:
•A car that offers the luxury of a Rolls-Royce in a vehicle that can cross any terrain
•A car that meets our customers’ highly mobile, contemporary lifestyle expectations
•A Rolls-Royce that is as much about the pioneering, adventurous spirit of Charles Rolls as it is about Sir Henry Royce’s dedication to engineering and innovation
•A car that appropriately reflects Rolls-Royce’s brand promise of effortless luxury
•A high-bodied car, with an all-new aluminium architecture
•A unique new motor car worthy of carrying the Spirit of Ecstasy into the future"
