Rolls-Royce sales also slipped this year, despite adding a single model, the Rolls-Royce Phantom Drophead Coupe last year, which doubled the number of models. Under parent BMW, the Rolls-Royce brand relaunched itself with a single model, the Phantom sedan, which went on sale in the U.S. in May 2003. It was the only model until the convertible version appeared in September 2007. Rolls is also adding a two-door hardtop Phantom Coupe later this year, as is an all-new, smaller and (somewhat) less-expensive sedan.
