Pictures of a one-off BMW Z3 powered by a V12 engine were released on Facebook, revealing a secret project BMW was working on many many years ago. This car is part of a secret M Garage where they keep their most radical concepts and one-offs. There’s no details available on the specs of this Z3, or the kind of speed it achieves, but if it’s the same V12 used in the old 850Ci, it’d have about 300 hp. The car should also have comedy handling, what with the weight of that V12 upsetting its balance.

So this is what happens when BMW lets its engineers go mad!
