2015 Mercedes-Benz S-Class: What's New, Specs & Features
Last updated August 4, 2026

The biggest change for the 2015 Mercedes-Benz S-Class is a much broader lineup, led by the all-new S-Class Coupe. The sedan is not redesigned, but it gains the S 550 Plug-In Hybrid, V12-powered S 600, and S 65 AMG.
About the 2015 Mercedes-Benz S-Class
6th-generation S-Class era: W222 sedan, second model year; C217 coupe, first model year.
Mercedes positions the S-Class as its flagship luxury car and openly frames it as the benchmark the rest of the industry follows. Its core appeal is quiet, effortless comfort backed by advanced safety technology, a richly finished cabin, and strong but smooth powertrains. Buyers choose an S-Class less for flashy gimmicks and more because it delivers the full-size Mercedes experience: serene highway travel, prestige, and technology that often reaches other cars later.
The S 550 remains the core luxury sedan, pairing a 449-hp twin-turbo V8 with an air suspension and a leather-lined cabin. The lineup stretches from a plug-in hybrid that can cover short trips on electricity to the comfort-focused S 600 and 621-hp S 65 AMG, while the S 550 4MATIC and S 63 AMG families also include the new two-door coupe.

2015 Mercedes-Benz S-Class Reviews
What owners are saying about the 2015 Mercedes-Benz S-Class.
“I love my S550. The only complaint I have is that the gas tank is not large enough. We live several miles out in the country from the closest town, so when I go anywhere, I have to drive approx. 20 miles just to get there. I can go only about 4-5 days before having to stop for gas.”
“Not ideal to switch controls for speed and blinker between E and S class. Lane-keeping vibration and sensitivity was better in E. Only disappointment is steering assist. Why does it CONSTANTLY show red hands on straight roads? Do they not have straight roads in Germany like in the U.S.? The feature is not usable like that and needs to be turned off.”
