Franco Sbarro invented the hubless wheel in 1989. On the current concept, the front wheels seem to float on aerodynamic struts. The wheel turns on a fixed ring attached to the strut.

Hubless wheels are also used on the rear. The brake discs are configured as rings mounted to the insides of the wheels, with calipers facing outwards.

The tight cockpit has room for two. A touch-screen LCD is mounted on the console and handles controls for climate and infotainment. The unique interface was designed by Delphi.

All of the buttons on this interface are virtual and respond to touches and gestures. For example, you can swipe a finger around the volume control to adjust the audio level. The navigation map can be moved around by swiping, as well.

The phone system has this keypad, along with a phonebook. Although the Sbarro roadster concept might not see production, Delphi could use this interface technology in other cars.
