Apparently they made 3 or 4 prototypes, one used in a movie. The specs on the engine are a bit mind numbing. I think it would be cool to have one on the autobahn and open it up.

To date, unlike the M70-derived engine of the E32 Goldfisch, very little is known about the V16 of the 100EX. Just a few details exist on the Internet, and they describe a 9.0-liter V16 (likely based on the period N73) with twin-cam heads driving a total of 64 valves. Output is quoted as 770 horsepower at 5,900 rpm, with an astonishing 1,100 pound-feet of torque arriving at 2,900. Performance figures don’t exist, but a six-speed automatic transmission—the technology of the era—was used, and the 100EX measured over 220 inches in length. Compared to the 6.7-liter SOHC, 32-valve Goldfisch engine, which produced just over 400 horsepower and 450 pound-feet of torque, enough to propel a long wheelbase E32 7 Series to 175 mph, the Rolls-Royce V16 represented another realm of performance—too bad they were never put into production.
