Hyundai unveils egg-shaped car

Hyundai has designed a bizarre egg-shaped concept vehicle, offering a new line in travel for commuters.

The 'E4U' is an oval-shaped, open-topped single person 'scooter' similar to a Segway.

But doing away with the traditional two-wheel design, the prototype instead uses a 'rotating semispherical part' - which looks like the lower half of a sphere and is constantly rotating.

It works like the lower half of a ball and is used for propulsion instead of wheels.

While the vehicle is stationary when standing upright, as soon as the driver pushes forward it drives on at walking speed.

The driver stands on a small platform and directs the vehicle by tilting it so that different sides of the semisphere contact the ground.

It was unveiled at the Seoul Motor Show, in South Korea, just four months into development, and currently has two safety wheels at the rear which stop it tipping from side to side.
