About The 2006-2014 Mercedes-Benz S600
The Mercedes-Benz S600 was the top-tier W221 S-Class model, aside from the AMG models. Mercedes-Benz produced three variants of the S600: the base model, the Guard, and the Pullman Guard. The base model is by far the most common, as the other two models were not standard production models.
The S600 Guard is an armored version of the base model, and the S600 Pullman Guard is armored with a limousine bodystyle. Unless you’re in the market for an armored vehicle, the Guard models are mostly impractical. The armor adds extra weight, contributing to worse fuel efficiency, and the Guard-specific parts may be difficult to come by.
Most W221 models came in variants of either standard-wheelbase (SWB) or long-wheelbase (LWB), however the S600 was only sold in LWB format. Typically, the top W221 models only came in LWB format. This is true for the S600 (top non-AMG model) and the S65 AMG (top AMG model).
Basic Information
The S600 was given the chassis code of 221.176. Production for the pre-facelift model began in November 2005 and ended in May 2009. The post-facelift models began production in May 2009 and ended in February 2014. Mechanically, these cars were virtually identical. Most post-facelift differences involve cosmetics, electronics, and standardizing previously optional equipment.
