1. 2016 Acura NSX

Of all the prototypes, this one was hard to digest, especially when it was coming from a Japanese automaker. In defense of my argument, Asian companies play on the safe side and when Acura Concept dropped the curtains in 2012, I thought it will never see the day of realization. Must say my faith was restored in Acura when the real car turned out to be just as fascinating.
