The new Mercedes-Benz S-Class Cabriolet is exceptionally rigid. Innovative solutions such as the luggage compartment bulkhead made of aluminium and magnesium as well as the aluminium rear floor also lower the bodyshell weight to the level of the S-Class Coupé. The standard-fit roll-over protection system behind the rear head restraints features pyrotechnic initiation of the actuators for the first time, in addition to which the roll bars themselves are moved into position by a gas generator.

Mercedes-Benz lays claim to building the world's most comfortable convertible. When it comes to climate comfort, the enhanced automatic wind protection system AIRCAP, the AIRSCARF neck-level heating system, the heated armrests, the seat heating also in the rear plus the intelligent climate control ensure that this is indeed the case. In contrast to conventional systems, the climate is controlled fully automatically. This means that the driver does not need to select a mode for closed or open top, nor is it necessary to save a temperature setting for these driving conditions..
