14. Mazda Furai

Debut: North American International Auto Show
Year: 2008
Complex Says: Furai means "the sound of wind" in Japanese, though we have an inkling you'd hear a lot more than that if you witnessed this beast on a racetrack. Based on a Mazda Le Mans prototype and powered by ethanol, it was Mazda's vision of a greener zoom-zoom future. There were rumors of its racing in Le Mans and possibly seeing production. We still have our fingers crossed.
