The 100 EX concept was produced, and presented in 2004, to celebrate the 100th anniversary of the meeting of businessman Charles Rolls and engineer Sir Henry Royce in 1904.
The 101EX shares its aluminium space frame chassis technology with the 2003 Phantom, albeit in a shortened version. The car is 9.5 in (241 mm) shorter than the Phantomsaloon, with a lower roofline and shallower glass area. Power comes from the BMW 6.75L V12 engine.
The updated body styling of the 101EX would eventually serve as the basis for the Phantom Drophead Coupé and Phantom Coupé. The latter car was featured in the film Johnny English Reborn, and for the film Rowan Atkinson persuaded BMW to fit one of the three or four V16s originally developed for the 2003 Phantom saloon into the movie coupé, to which BMW agreed.[2]
