Mazda Furai Concept

Designer Franz von Holzhausen says it's supposed to look like streamers fluttering in the wind. It's the fifth concept in Mazda's Nagare (flow) series and the visual realization of zoom zoom. If you say so, Franz.

Furai's a concept that's breathtakingly simple on paper, yet fiendishly complicated in execution: "Let's take a full race chassis and drop a concept-car body on top."

Of course, there's more to it than that -- you need an engine, in this case a 458-horsepower, triple-rotor race-ready unit running on pure ethanol (E100) -- the first rotary to do so. Mazda refers to the rotary/ethanol combo as sustainable zoom zoom.
