I know this might be a little old but Mazda Furai is pretty cool.
This Mazda Fuari looks amazing going down the track and I gotta say I would want to watch more racing if all the cars were this cool looking. The Furai sounds amazing too. The word Furai in Japanese means "sound of wind". Furai is able to generate about 80 percent of the downforce of the original race-spec bodywork. Most concept cars don't even run but this one as you can see by the video is running around the track at speed. The Furai has aggressive lines plus elegant styling it will make you look even if you don't like cars. Furai is one of those special cars that really show off what a concept car can represent. Very inspiring and stylish.
