The Mercedes-Benz B-Class 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
Over its entire life cycle, comprising production, use over 160,000 kilometres, and recovery, the B 180 BlueEFFICIENCY (Combined fuel consumption (petrol): 5.2 l/100 km; combined CO₂emissions: 122 g/km*) gives rise to 16 percent (approximately 6 tonnes ) less CO₂ emissions than its predecessor.
 Status environmental certificate/certificated values: 2011
In comparison with the predecessor the new B 180 BlueEFFICIENCY reveals several differences in the material mix. The new B-Class has an approximately 6 percent lower steel content at around 58.4 percent, while the proportion of light metals, at 10.3 percent, is around 4 percent higher than the predecessor model.
Secondary and renewable raw materials
In the new B-Class, a total of 75 components with an overall weight of 39.2 kg can be manufactured partly from high-quality recycled plastics. The mass of the approved components made from recycled material has thus been increased by 13 percent compared with the predecessor model. Typical applications include wheel arch linings, cable ducts and boot linings, and underbody panelling, which are largely made from polypropylene.
In automotive production, the use of renewable resources concentrates on the vehicle interior. In the new B-Class, the natural fibres largely comprise coconut and wood fibres as well as honeycomb cardboard, which are used in combination with various polymer materials for series production. In the new B-Class, a total of 21 components with a combined weight of 19.8 kilograms are produced using natural materials. The total weight of components manufactured with the use of renewable raw materials has thus increased by 29 percent compared with the predecessor. For the tank ventilation the Mercedes engineers have also drawn on a raw material from nature: wood-based coke is used in the activated charcoal filter. This porous material adsorbs the hydrocarbon emissions, and the filter is constantly regenerated during operation.
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.
