Powered by a new twin turbo 6.6-litre V12 engine, the Rolls-Royce Ghost is virtually silent, with 80% of its torque available from idle. Coupled with the 8-speed ZF gearbox, it accelerates from 0-62 mph in just 4.9 seconds and has a governed top-speed of 155mph. The Ghost was unveiled at the Frankfurt motor show in September 2009.
