As expected, the S-Class Coupe and Cabriolet updates for the 2018 model year are similar to that found on the sedan. Both the Cabriolet and Coupe do have a revised front and rear fascia, with each variant having their own changes. All S-Class variants now also come equipped with the new LED headlights and OLED taillights.

Step inside, and you'll find the updates of the S-Class sedan to have been carried over to both the S-Coupe and Cabriolet. Sitting directly infront of the driver is now a three-spoke steering wheel, which incorporates touch control buttons, as opposed to the two-spoke design of the pre-facelift model. There is also new trim options available with a new 64 color ambient lighting system. Completing the interior update is the new 12.3-inch COMAND infotainment screen, which is now merged with the instrument panel for a clean, seamless look.
