767i V16 - The ultimate flagship limo?

Awesome design exercise by BMW in 1987 to showcase a crazy new V16 they were developing from two bolted-together V8s. The 750iL was the only model big enough to accommodate the giant motor and even then all the boot space had to make way for the twin radiators, which explains the giant NACA-ducts on the rear quarter-panels.

Here's a great bit of BMW literature on the project that someone has generously scanned in:
