With the four-door design vision Audi Aicon, the brand with the four rings is presenting a autonomous Audi of the future - with no steering wheel or pedals. As a design concept, the four-door 2+2 boldly leaps ahead to show the exterior and interior design of the next decades. The wheelbase measures 3,470 millimeters (11.4 ft). That's 240 millimeters (9.4 in) more than with the long version of the new Audi A8. The glass roof panels can block out the sunlight, if desired.
