1.14K 0

For the first time, a diesel car has achieved the maximum score in a European emissions test. It is a test set up by the Consumer Association. The Mercedes-Benz C 220 d was therefore qualified as ‘green’, just as fully electric cars.

The Mercedes-Benz C 220 d achieved a 10 in the Clean Air Index test. The test considers and measures harmful exhaust gases. Electric vehicles automatically get the maximum score thanks to their lack of emissions.

The Energy Efficiency score of the Mercedes in the Green NCAP, the name of the overall program, is still lagging behind that of electric vehicles. As a result, the car does not get 5 stars, but 3 stars. For a fair comparison, fuel consumption is converted to kWh.

The BMW i3, Hyundai Ioniq and Nissan Leaf are the greenest vehicles according to Green NCAP. The Volkswagen Up and Opel Corsa with 1.0-liter petrol engine come closest because of low emissions and favorable fuel consumption.

The Mercedes-Benz C 220 d scores a 10 on the Clean Air Index

The Mercedes-Benz C 220 d scores a 10 on the Clean Air Index, but only a 5.3 on the Energy Efficiency Index. The Renault Scénic Blue dCi 150 also achieved a very green score with an 8.6 on the Clean Air Index test.

The organizers, a joint venture between European consumer organizations, industry associations, universities and governments, are not yet based on the so-called ‘source to wheel’ principle. For example, this also looks at the environmental impact of the production process. In the long term, that must be taken into account, they say in a press release.
