Mercedes F700

Mercedes-Benz pointed the way toward future designs of its S-Class luxury sedan—and showed off a completely new kind of internal combustion engine—with a concept it calls the F700.

The ultra-low, wavy and sleek body of the F700 falls in behind a huge horizontal grille reminiscent of the one on Mercedes's Ocean Drive concept, but the rest of the body is a completely new, 21st-Century rendering of the S-Class, called Aqua Dynamic. It's shorter overall than the current S-Class, but it has a much longer wheelbase and a roomier interior because the seats are so compact. The headlamps are comprised of three rows of white LEDs, and the rear doors are rear-hinged (a.k.a suicide doors).
