The eRinGo car is a rather strange concept car. A 2-seater that's capable of converting back & forth between 1 & 3-wheeled driving, depending on the curves of the road ahead, eRinGo looks like a half-crushed can of Heineken. Yikes! It has a cool 2 steering wheel concept - wherein the passenger on either side can take over driving duties - great if your friends are the agreeable sort willing to hand over the keys at any moment! I have to admit I kinda like that concept! lol
The Quadski is a four wheeler that transforms into a super fast jetski!
