S-Class convertible: Mercedes Ocean Drive concept

Mercedes today revealed its Ocean Drive concept, which will be on display at the North American Auto Show in Detroit early next month. The much-rumored four-door convertible is described as a one-off creation, but recent media reports indicate it could see production in a year.

Apart from the four doors, the unique concept features a very large and upright radiator grille, LED headlamps and taillights, and two-tone paintwork. The long side-window opening is not interrupted by a B-pillar or window frames.

The design study is based on the twelve-cylinder Mercedes-Benz S 600, and features an innovative soft-top mechanism with smooth operation and fast closing times, radar-based Distronic Plus, and the Airscarf neck-level heating system on all four seats. Gallery after the jump...
