Rolls-Royce 101EX

In 2004, the 101EX, a grand tourer coupe prototype based on the 100EX, was presented at the Geneva International Auto Show.

The 101EX shares its aluminium space frame chassis technology with the 2003 Phantom, albeit in a shortened version. The car is  shorter than the Phantom saloon, with a lower roofline and shallower glass area. Power comes from a BMW 9.0L V16 engine. It debuted at the 2008 Geneva Motor Show. This car was featured in the film Johnny English Reborn, and for the film Rowan Atkinson asked of BMW to use one of the V16s intended originally for the Phantom, to which BMW agreed.

The 101EX produces  at 5900 rpm and  of torque at 2900 rpm.

The updated body styling of the 101EX would serve as the basis for the Phantom Drophead Coupé and Phantom Coupé.
