Back in the day, a Rolls-Royce looked pretty much the same as a Bentley, but with a different grille. Once BMW took over Rolls-Royce, however, it was faced with the challenge of visually separating itself from its former sister brand. And most would agree that it did so pretty well. But its cars have looked pretty much the same ever since. What Rolls-Royce needs, then, is a bit of a design shake-up. And that's just what this latest appointment could bring.
