14: Acura Advanced Sedan
Hitting the auto show circuit in 2006, the Acura Advanced Sedan was something out of the ordinary. The sharp razor-edged styling was both terrifying and advance for the time. Acura had become sort of an afterthought in the luxury car market and needed to reinvigorate itself. A lot of the styling cues came from the MDX SUV of the same period and the next-generation NSX coupe.

The overall look of the car is strikingly similar to a gangster coupe of the 1930s. Maybach sort of mimicked the design with their Maybach Exelero, albeit a more put-together product. Acura is always trying to build on its performance reputation, and the Advanced Sedan was a concept that looked to embrace luxury and opulence.
