Mercedes-Benz CLS

The Mercedes-Benz CLS not only meets the highest demands in terms of safety, comfort, agility, and design, but also shows significant improvements regarding the examined environmental aspects over the entire lifecycle compared to the predecessor.

Life Cycle Assessment

Thanks to its higher efficiency in the use phase compared to the previous model, the CLS 350 BlueEFFICIENCY produces however over the whole lifecycle, 30 percent lower CO₂ emissions (approximately 24 tonnes [1]) than those of its predecessor.

Regarding the NOx emissions they could be reduced by 21 percent (8 kilograms [1]) compared to the previous model.

Material composition

In comparison with the predecessor the new CLS 350 BlueEFFICIENCY reveals several differences in the material mix.

The new CLS has an approximately 3 percent lower steel content at around 53.5 percent, while the proportion of light metals, at 16.3 percent, is 2 percent higher than in the predecessor model.

Secondary and renewable raw materials

In the base variant of the CLS, a total of 61 components with an overall weight of 49 kilograms can be manufactured partly from high-quality recycled plastics. Thus, the weight of secondary raw material components could be increased significantly around 96 percent compared to the previous model. Typical areas of use are wheel arch linings, cable ducts and underbody panels, which consist for the most part of polypropylene. For the front wheel arch linings of the CLS, for example, a recyclate is used that is composed of reprocessed vehicle components: these comprise starter battery casings, bumper covers from the Mercedes-Benz recycling system, and process waste from cockpit production.

In automotive production, the use of renewable raw materials is concentrated primarily in the vehicle interior. Established natural materials such as leather, cellulose, cotton, flax, sisal, kenaf and wool, are also used, of course, in series production of the CLS. In the base variant of the new CLS, a total of 56 components with an overall weight of 30.8 kilograms are made using natural materials. The total weight of components manufactured with the use of renewable raw materials has thus increased by 9 percent compared with the preceding model.

Allergy-tested car cabin

Since 2016 all new Mercedes-Benz cars are awarded with the Seal of Quality from the European Centre for Allergy Research Foundation (ECARF).

The ECARF Seal of Quality is used by ECARF to designate products that have been scientifically tested and proven to be suitable for allergy sufferers.
