Mercedes-Benz B-Class Electric Drive

The B-Class Electric Drive meets many customers’ demands for locally emission-free motoring without foregoing the hallmark attributes of a Mercedes-Benz: safety and comfort. And, let’s not forget: exhilarating driving pleasure.

Life Cycle Assessment

Over the entire life cycle, comprising production, use over 160,000 kilometres and recycling, the Sports Tourer B 250 e (power consumption: from 16.6 kWh/100 km; combined CO₂ emissions: 0 g/km*) gives rise to 24 percent (7.2 tonnes – EU electricity grid mix [1]) or 64 percent (19 tonnes – electricity from hydro power [1]) less CO₂ emissions than the B 180.

Regarding the NOx-emissions they could be reduced by 15 percent (approximately 4 kilograms – electricity from hydro power [1]) compared to the previous model.

Material composition

A comparison of the B-Class Electric Drive with the petrol variant reveals marked differences in the materials mix. As a result of the alternative drive components, the proportion of steel in the B-Class Electric Drive is around 8 percent lower, for example, while the shares of light alloys and non-ferrous metals are each approx. 3 percent higher and the share of precious metals is approx. 4 percent higher than for the petrol variant. The share of service fluids is almost 2 percent lower, due to the absence of fuel.

Secondary and renewable raw materials

In the B-Class Electric Drive, 58 components in all with an overall weight of 31.9 kilograms can be manufactured party from high-quality recycled plastics. Typical areas of use are wheel arch linings, cable ducts and underbody panels, which consist for the most part of polypropylene. Compared to the combustion-engine variants of the B-Class, the Electric Drive differs with regard to components which are directly related to the drive system, such as the plastic fuel tank.

In automotive production, the use of renewable raw materials is concentrated primarily in the vehicle interior. Natural materials employed in series production of the Sports Tourer B 250 e consist primarily of wood fibres and honeycomb cardboard in combination with various polymer materials.

In all, 13 components in the new Sports Tourer B 250 e with a total weight of 15.3 kilograms are made using natural materials.

Allergy-tested car cabin

Mercedes-Benz has also been awarded the Seal of Quality from the European Centre for Allergy Research Foundation (ECARF) for the current B-Class.

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.
