Life Cycle Assessment
Thanks to its higher efficiency in the use phase compared to the previous model, the new E-Class E 220 d (Combined fuel consumption (Diesel) 4.3–3.9 l/100 km; combined CO₂ emissions: 112–102 g/km*) produces however over the whole lifecycle, 29 percent (approximately 15 tonnes ) lower CO₂-emissions than those of its predecessor.
Regarding the NOx-emissions they could be reduced by 40 percent (approximately 30 kilograms ) compared to the previous model.
The plug-in hybrid model E 350 e (Combined fuel consumption (petrol): 2,5–2,1l l/100 km; combined CO₂ emissions: 57–49 g/km*) combines a 65 kW (88 hp) electric motor with a four-cylinder petrol engine displacing just under two liters with 155 kW (211 hp).
In the production phase the E 350 e gives rise to a higher quantity of CO₂-emissions especially caused by the additional hybrid-specific components. Over the entire lifecycle comprising manufacture, operation over 250,000 kilometres and recycling, however, the plug-in hybrid has clear advantages.
External charging with renewable electricity from hydro power can cut CO₂ emissions by around 63 percent (42 tonnes ) compared with the E 350 CGI.

In comparison with the prede-cessor E 220 CDI the new E 220 d reveals several differences in the material mix. Due to lightweight construction measures in the areas of body shell and chassis, the new E 220 d has an approximately 7 percent lower steel content, while the proportion of light alloys increases by the same amount.
Secondary and renewable raw materials
In the base variant of the E-Class, a total of 72 components with an overall weight of 54.4 kilograms can be manufactured partly from high-quality recycled plastics. Thus, the weight of secondary raw material components could be increased significantly around 30 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.
With the material Dinamica® a high-quality secondary raw material is now also used in the interior of the new E-Class. Dinamica® is a microfiber made of recycled polyester and water-borne polyurethane. The recycled polyester contained in Dinamica® derives e.g. from textiles and PET bottles. Dinamica® has a suede leather optic and haptic and is used in the interior e.g. as seat cover, roof and pillar liner.
In automotive production, the use of renewable raw materials is concentrated primarily in the vehicle interior. Established natural materials such as flax and cellulose fibres, wool, cotton and natural rubber are also used, of course, in series production of the E-Class. In the base variant of the new E-Class, a total of 90 components with an overall weight of 33.1 kilograms are made using natural materials.
The total weight of components manufactured with the use of renewable raw materials has thus increased by 59 percent compared with the preceding model.
Allergy-tested car cabin
The current E-Class has also been awarded 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.
