Green NCAP 2020 environmental test

This year, its rating system has been revised by Green NCAP, an organization set up by Europe’s largest car clubs, car advocates and transport ministries.

Green NCAP has previously only looked at the overall emissions and efficiency of cars, but from 2020 it will also monitor emissions of greenhouse gases, especially carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). . In general emission studies, more attention is being paid to ammonia (NH3) and various nitrogen oxides (NOx).

The Green NCAP is the first round of 24 types examined according to the new system of conditions. Gasoline, diesel and gas-powered models, hybrids and purely electric vehicles, front-, rear- and all-wheel-drive models, automatic and manual transmission powertrains were on the list.

The cleanest non-electric car: Toyota C-HR 1.8 Hybrid

Since purely electric vehicles do not emit any harmful substances at the point of use, they received maximum scores at the first and third test points. They also earned ten points for efficiency – the organization measured and aggregated the energy consumption of cars under different driving conditions; in the end, there was only a tenth kWh difference per 100 kilometers between the Renault Zoe and the Hyundai Kona – the “consumption” of the two cars is virtually the same.

Green NCAP has also promised that in the future, the lifetime emission values ​​of vehicles, such as the environmental footprint of battery production in electric cars, will also be taken into account.

Yellow indicates grossly poor results

There was an exciting race behind the two electric cars: for third place, Toyota’s hybrid city crossover, the C-HR 1.8 Hybrid, raced a premium diesel car: the Mercedes-Benz C220d. The latter eventually slipped to fourth place, but its excellent performance is a good indication that it is indeed possible to produce a clean-running diesel car.

Maybe, but not everyone succeeds: while all diesels are economical and therefore perform well in terms of emissions, overall they have not achieved very good results. The investigation found that there were a worrying number of them operating nitrous oxide is released into the atmosphere. There are also six types that scored less than one in this field (out of a possible ten).

The cleanest diesel car: Mercedes-Benz 220C

Surprisingly, although logically, the relatively poor results of compressed natural gas models. While CNG is explicitly considered by the public and the industry as a clean technology, the low energy density and high methane content of the fuel take revenge in the complex analysis of Green NCAP. Incidentally, the organization also consulted European consumers when drawing up the criteria system; the aspects examined were the result of a thorough survey.

Unexpectedly, the poor performance of the hybrid Honda CR-V: according to the justification, the car bleeds during a cold start or on the highway, its hybrid system did nothing to reduce emissions.
