BMW i-FD Concept Car by Feliciano Ruy-Diaz as a sort of 5 Series-sized sports sedan. The inspiration for the styling came from a number of sources, including Great White sharks, ancient Greek armor, and the buildings of world-famous Spanish architect Santiago Calatrava. Ruy-Diaz doesn’t elaborate on the i-FD’s drivetrain. But being a proposal for a BMW i model it must be either electric or hybrid powered. And the fact it has an exhaust pipe is a clear indication there’s an internal combustion engine designed to fit somewhere within.
