It's now confirmed Rolls-Royce will use the Geneva Motor Show to unveil its latest and smallest car. Rolls has always been aimed at a more-affluent market, but CEO Tom Purves may be going after a slightly younger and different market with the new car. He says the car will be "more like a well cut sports jacket than a tuxedo ."

So far the car has been called the RR4, but that name will absolutely change, possibly using the historic Sliver Ghost name for production. The car Geneva Motor Show will not give any clue to the car's final name. The concept will show up with the letter EX (for experimental) followed by a series of numbers. Although this will be a concept with an experimental name, the production car will be very close to the car shown in Geneva.

So far speculation has the engine for the RR4 coming out of BMW's parts bin, but Purves has now confirmed that the engine will be a V12 not seen before on any BMW. In total about 80 percent of the RR4 will be unique to Rolls. Pieces that are not seen usually by the customer will be the ones shared with other products made by the corporate parent BMW.

No word yet on U.S. pricing, but estimates in the U.K. have been between £160,000 and £200,000. Which (thanks to rates favorable to the dollar) is about $240,000 and $299,000 at current rates.
