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.
Steel/ferrous materials account for slightly the half of the vehicle weight (55.2 percent) in the new B 180. These are followed by polymer materials at 21.8 percent and light alloys as third-largest group with 10.0 percent. Service fluids comprise around 4.7 percent. The proportions of other materials (e. g. glass) and non-ferrous metals are somewhat lower, at about 3.9 and 2.8 percent respectively. The remaining materials – process polymers, electronics, and special metals – contribute about 1.8 percent to the weight of the vehicle.
In the new B-Class a total of 121 components plus small parts such as push buttons, plastic nuts and cable fasteners with a total weight of 60 kilogrammes can be produced partially from less resource consuming materials.
Manufacturing vehicles requires a high degree of material usage. For this reason there is a developmental focus on further reducing the use of resources and the environmental impacts of the materials deployed. To this end, renewable raw materials and recycled plastic materials (recovered plastic) are used. Apart from the economical use of resources, reconditioning components and recycling the raw materials used also play an important role.
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-Benz 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.
