The RR4 -- the Rolls-Royce that asks that you "don't call me 'baby'" -- is slowly undressing, striptease-like, before its final reveal at the 2009 Geneva Motor Show. Previous spy shots hinted at rear suicide doors, or coach doors as Rolls-Royce refers to them, and now it is official: the hinges on the rear door are on the rear of the door. The car has plenty of Phatom-esque cues, and although it doesn't look anything like the initial sketch, it looks like it could be a very attractive proposition when it shows up for the big dance. Still no word on engines, but we have no doubt its output will be something along the lines of prodigious.

After having maxed-out the Phantom range with sedan, coupe and convertible variants, Rolls-Royce has been hard at work preparing its second range. Known tentatively as the RR4 (following in succession after the three Phantoms), the new "baby Rolls" will be anything but, and is expected to be unveiled next March at the Geneva show.
