The Portugese designer AndrÃ© Costa took another novel approach to ease of 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.
Check out the pictures of this futuristic Peugeot’s concept car. 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.
The front-end conceals two small additional wheels which only operate as safety supports. In the future it could be possible to make such a vehicle self-balancing using gyroscopes and balance sensors.
This is already employed on the Segway scooter and is suggested for the EMBRIO one-wheeled motorcycle concept. The Moovie concept car built by Peugeot has a length of just 2,3 metres (7.6 ft) and width and height of 1,5 metres (4.9 ft). Access is created by two large sliding doors placed in the centre of the hub-less side-wheels.
