Overview

The W220 S-Class introduced Airmatic air suspension, Active Body Control (ABC), COMAND infotainment, and keyless-go as standard features on the flagship sedan. It was lighter and more technologically advanced than the W140 but carried a reputation for expensive electronic failures. The S55 AMG with its supercharged V8 and S600 V12 represented peak early-2000s luxury performance.
