4. Peugeot Moovie Concept Car
The Portuguese designer André Costa took another novel approach to ease city parking and manoeuvring. His design Moovie, made for the 2005 Concours de Design Peugeot, features two huge hub-less side-wheels which are used for both driving and steering. Each wheel is independently driven by an electric motor, allowing the Moovie to rotate on its own axis and squeeze into the tightest parking spots. To increase stability, the two side-wheels are tilted inwards under a ten degree angle.
