The Rolls Royce RR4/Silver Ghost is a V12, 6.6 litre turbo compressed unit with 500 hp and an eight speed transmission.
Managing Director Tom Purves has said that the interest of customers is increasing and the brand will come full circle with the production of the Goodwood, after the positive response to the 200EX, though the sedan will keep the classic ideals of the Spirit of Ecstasy.

This smaller Rolls has the irony of the “baby” nickname for a car that’s more than five metres long. While it’s not a Phantom, the 7 Series platform has dimensions that are still a lot more than city car - along with a style and charm that is far more than any “baby”.
Rolls Royce has released the first official drafts of the RR4, the new model designed to become the access point for the world to the “spirit of ecstacy”, and expected to generate important sales internationally. Until now we had glimpsed some prototypes and discussed the possible arrival of a diesel engine, but now we can view these designs, still a little rough, and see that the RR4 will continue the stylistic course of the Phantom while accentuating dynamism.
Design head Ian Cameron has said the RR4 will have some of the Phantom’s grunt, emphasising the dynamic aspect and driving experience, while proposing smaller dimensions compared to the big sister.
The car has been now been defined down to the last detail, and should be revealed throughout the course of 2009. While waiting for the commercial launch, planned for 2010, Rolls is considering a second line for production at the Goodwood facilities.

Edmunds’ Inside Line has published some new spy shots of the RR4, the baby-Rolls Royce that will be positioned halfway between the Phantom and a BMW 7 Series.
According to rumours, there will be some similarities to the BMW 7 Series, although the RR4 will be wider, longer and taller than the flagship BMW. Even the wheel base will be longer. The RR4’s main competitor will be the Bentley Continental Flying Spur. For the engines it’s likely we’ll see a more underpowered version of the Phantom’s V12, 6.75-litre, possibly a 6-litre 441 hp or a 4.4 litre twin-turbo at 408 hp that will debut on the BMW X6 50i. All these engines though, suffer from a marked power deficiency compared to the Flying spur whose W12 comes in at around 560 hp. 

The English magazine Car has reported that the “baby Rolls” style will be based on the much more prestigious Phantom Drophead. There is great expectation surrounding the new model, especially considering that the weight of the sales boom expected for the next few years will all be on its shoulders.
It’s not difficult to believe that this proposal is very close to reality, given that the Rolls design is compulsorily linked to certain characteristic elements such as the powerful front grill and the proportions of the body-work. What has been judged as the enemy of the Bentley Continental Flying Spur will be based on the next BMW series 7, a big step which will give life to an entire family of models.
From there a new coupè and cabriolet will emerge, as has already happened with the bigger Phanton, especially as the VW magament for Bentley wanted, which in fact has in its range the Flying Spur, Continental GT and the GTC. Thanks to this operation Rolls will be in a position to close the gap with its ex-allies, who are already moving towards 10,000 units a year.
