In spring 2019, Green NCAP (Euro NCAP’s daughter) was founded, whose purpose is to assess new cars environmental friendliness. The results of the first testing are surprising.
Recently Green NCAP has made its testing. They took the following models to check their performance for clean air and energy efficiency: an all-electric Nissan Leaf, a methane-fueled Audi A4 Avant g-tron, a gasoline Opel Corsa, as well as a couple of diesel cars – Renault Scenic dCi 150 and Mercedes-Benz C-Class C220 d 4Matic.
In the eco-friendliness test the Nissan Leaf expectedly got the highest Clean Air Index – 10 out of 10. Surprisingly, the Mercedes’s result is the same, although it works on heavy fuel!
According to experts, the success of the German vehicle is due to an effective cleaning system it is equipped with.
As for the other three models, the Audi A4 Avant‘s Clean Air Index is 8.7, the Renault Scenic’s – 8.6, and the Opel Corsa’s – 9.0 points.
The Energy Efficiency Index figures are as follows: the Leaf has 8.5, the C220 d 4Matic – 5.3, the A4 Avant g-tron – 4.7, the Scenic – 5.9, the Corsa – 6.0.
As you can see, the diesel Mercedes-Benz C-Class is noticeably inferior to the Nissan Leaf, so its final score is 3/5, while the Japanese electric car won the highest 5/5 Stars.
The Green NCAP laboratory tests included Cold and Warm tests, Eco and Sport modes, Highway, plus On-Road Drive figure added.
