Recently, concept cars have become boring. Most are thinly disguised production-destined vehicles lacking a certain amount of crazy-cool. The Frankfurt Motor Show is shaping up to buck that trend. Example? The Hyundai ix-Metro has plenty of crazy.

Yes, of course it's a hybrid. What concept car isn't these days? It's got a meager 1.0-liter gas motor cranking out a heady 125 HP and mated to some form of hybrid drive system still behind the curtain. That's probably more or less the tech that indicates a future product, so, the boring part. The ix-Metro makes up for that with psychedelic bodywork and an interior inspired by Flight of the Navigator.
