Electric B-Class awarded environmental certificate

The German TUC automotive testing organisation has awarded an environmental certificate to the Mercedes-Benz B-Class Electric Drive, writes Brian Byrne.

Though the version isn't available here, it offers a 200km range and CO2 emissions over its entire production and usage life cycle that are up to 64 percent less than the petrol B180.

CO2 emissions during the use phase depend upon the method used to generate electricity. In 160,000 kilometres of driving use, the new B-Class Electric Drive (NEDC combined consumption from 16.6 kWh/100 km) produces 11.9 tonnes of CO2, assuming use of the EU electricity mix. When electricity generated by hydroelectric means is used to power the electric vehicle, the other environmental impacts relating to electricity generation are also almost entirely avoided.

The B 180 (NEDC combined consumption 5.4 l/100 km) on the other hand emits 23.8 tonnes of CO2 during the use phase.
