Summary

The 2017 S 550 Cabriolet is one of the most refined vehicles of its era, offering the AIRCAP system for reducing air currents and the AIRSCARF for heating the neck, allowing open-ceiling movement even at low temperatures. The V8 BiTurbo engine offers an instantaneous power and a characteristic but restrained noise. Although it is a heavy vehicle (over 2 tons), the 9-speed transmission makes it surprisingly efficient on the highway. The points to be checked in this model are the complex ceiling mechanism and the sensors of the air suspension system (Airmatic), which may require costly maintenance over time.
