Nissan develops an egg-shaped car whose body pivots 360 degrees so the rear end becomes the front.

The Pivo is shown Friday at a Tokyo Nissan showroom and is an experimental model that is not expected to go on sale for several years.

The three-seater electric car looks like a big egg on wheels. The body revolves in a complete circle, while its wheels stay put.

Pivo's steering, wheels, and other parts are controlled electronically by wireless signals, not mechanical links, making the turns possible.
