The Rolls-Royce RR4 is a new, smaller ultra-luxury saloon automobile from Rolls-Royce Motor Cars Limited. The 'RR4' designation is only the internal codename for the car; the final production name for the car has yet to be revealed.

Design concept

Designed by Ian Cameron, and engineered by Helmut Riedl who led the Phantom project,[1] the RR4 is aimed at those who don't want something as big/ostentatious as the Rolls Royce Phantom.

The car will probably use components from BMWs F01 platform that will underpin the next generation 7 series, with the platform itself aid to be flexible enough to allow the car to have a wheelbase, roof height, bonnet height and track widths all of its own. Other components will be supplied by BMW but will used in functional places unseen by the driver. The engine was rumored to be either a twin-turbo V8 or a V12 tuned to produce number below that of the Phantom.[2]

200ex concept

A concept car, named the Rolls-Royce 200EX, is to be officially unveiled at the March 2009 Geneva Motor Show, indicating the styling direction of the production RR4.

Unlike the aluminium-bodied Phantom, the 200EX is built from steel, which has a higher tensile strength and can therefore be made thiner.[3] Twenty percent of all components are shared with BMW Group cars, including the electrics. Most of the shared chassis components come from the latest BMW 7series, but the 200ex uses Phantom-style air springs. The engine is a new BMW V12, which will also be fitted to the latest 7, specially tuned to deliver more low-down torque to produce that special Rolls ‘waftability’.[4]

Rolls Royce Motor Cars also confirmed that the final production version would be launched at the September 2009 Frankfurt Motor Show.
