If a Phantom is too big and a standard Ghost too small, here’s the solution for buyers: the Rolls-Royce Ghost long-wheelbase. Rolls-Royce has added 15cm in length to the rear side doors of its standard Ghost to create more cabin space for passengers. We expect a length of 5.55m over the standard Ghost's 5.4m. Most other details, including the 425kW, 6.6-litre, V12 bi-turbo engine will be unchanged. The Rolls-Royce Ghost shares many components, and a platform, with parent company BMW's 7 Series.
