Rolls-Royce RR4

Rolls-Royce Motor Cars (BMW’s subsidiary that makes Rolls-Royces since 1998) has released preliminary sketches of its upcoming smaller car to be slotted under the Phantom range, debuting in 2010. The car is called the RR4 at the moment, but the production car may get another name.

Under the Rolls-Royce RR4’s engine hood is said to be a new engine unique to Rolls-Royce, but because of the many ways one can define unique, you can expect this to be a derivative of a BMW engine, perhaps a higher displacement version of BMW’s new twin turbocharged 4.4 litre V8. The underlying platform will likely be an adaptation of the new F01 platform that the next generation BMW 7-Series will use.

“Effortless performance and standard-setting levels of comfort and efficiency, executed with the utmost care and attention, remain fundamentals of Rolls-Royce design. The RR4 has a more informal presence than the Phantom models with a greater emphasis on driving. In design terms this is expressed through its slightly smaller dimensions and more organic form, yet with powerful, purposeful proportions. It is a true and uncompromising Rolls-Royce in every sense,” says chief designer Ian Cameron.
