The 2009 Mercedes-Benz S-Class - PART IV


Stuttgart, Germany, May 11, 2009

Market success: Number One in the luxury segment

- 270,000 units sold since the market launch in 2005
- The eight-cylinder S 500 is the bestselling model

The Mercedes-Benz S-Class remains unbeatable in the luxury class: with 270,000 units of the current W 221 series sold since its market launch in autumn 2005, it is the world's most successful luxury saloon. And as the trendsetter where innovative automobile engineering is concerned, it is seamlessly continuing the success story of its predecessors. Dr. Dieter Zetsche, Chairman of Daimler AG and CEO of Mercedes-Benz Cars: "The S-Class is the worldwide market leader. Thanks to innovative technology, first-class comfort and trailblazing safety systems, the Mercedes-Benz flagship model is seen as a pioneer in automobile development."

A dozen technical innovations entered series production for the first time in the W 221 series - from Brake Assist PLUS with radar sensors to the dynamic multicontour seat with an extended massage function, from Night View Assist with infrared technology to the improved COMAND system, from preventive PRE‑SAFE® occupant protection with additional functions to the Active Body Control suspension. The 2009 S-Class likewise leads the field in automotive development with a unique combination of radar and camera-based assistance systems, plus the first series-production hybrid drive system with a lithium-ion battery in the S 400 HYBRID.

Most important markets: United States, China and Germany

Accounting for one quarter of total unit sales, the United States of America are the largest market for the S-Class, followed by China. A major contribution to the success of the S-Class in China was made by the introduction in June 2008 of the S 350 4MATIC specifically configured to meet the wishes of Chinese customers. After the USA and China, the German home market is the third-largest market for the S-Class.

The most popular variant is the eight-cylinder S 500, which accounts for almost half of all worldwide sales, followed by the six-cylinder S 350 and the diesel-powered S 320 CDI, which also has six cylinders. In the 2009 S-Class this carries the model designation S 350 CDI BLUE EFFICIENCY.

The success story of the S-Class is also studded with numerous prizes and awards in international competitions. Here is a selection:

The technical highlights of the S-Class and its predecessors

Since 1951, when the model 220 began the direct lineage of the S-Class, Mercedes-Benz has delivered around 3.3 million passenger cars from this model series to customers. This means that in terms of tradition too, this prestigious saloon easily leads the field. The S-Class has always been a trailblazer for the latest automobile technology, and as such the advance guard for the entire Mercedes-Benz brand.
