Thinking of buying a car? These are the greenest vehicles on the market

• Impact Report 2020 Tesla's electric vehicles, more efficient than those of its rivals

More than two decades ago, the independent vehicle safety tests, EuroNCAP, were born to evaluate with objective tests the active and passive safety of each model on the market.

in order to further protect passengers and avoid serious injuries and deaths.

In the midst of a climate emergency, a twin institute that measures automotive toxicity has emerged:

.

The credibility of the tests, both safety and environmental, must be held in an

.

In this sense, GreenNCAP makes sure to

, most of them coming from car rental companies.

In no case, they assure, are they provided by the manufacturers.

Comprehensive measurements

The measurements are quite complex, but they address a crucial aspect: the difference between the official homologation granted to new vehicles and the actual figures for consumption, efficiency and greenhouse gas emissions during the actual circulation of the vehicle.

Thus, with a mixture of measurements in cold, on highways or in the conditions of maximum temperature, between the road and the laboratory the vehicles are evaluated.

As in EuroNCAP, this ecological evaluation body simplifies the results with the star system, in the style of the rating of hotels.

Only one tenth in the efficiency section separates the Nissan Leaf from the full.

Three parameters

The specific notes are divided into three aspects:

.

Every year we try to improve the analysis including small improvements that can change the note of the same model in 2020 and in 2021.

The star rating for plug-in hybrids (PHEV) takes into account polluting emissions, energy efficiency and greenhouse gases in two driving modes: mainly using the combustion engine and when the battery is the main source of energy.

The electrics

No car powered by fossil fuels reaches five stars

, an exclusive preserve of electric vehicles, among which there are few things that separate them, since

. The difference then lies in the almost negligible nuances obtained in the laboratory when using the car when it is cold or when it is already running or in cold or hot outdoor conditions.

.

The only one that achieves a 10 in the three plots

of those analyzed in 2021 is the

the urban one with an 87 kW electric motor and a 42.0 kWh battery.

, but the advantage in this section between some battery-powered cars is

.

By size and performance, the Lexus UX 300e is the most developed 'five-star' electric.

Only one tenth separates the

from the Italian utility.

Its 9.9 in efficiency makes it a 100% ecological car according to GreenNCAP.

The tenth for 10 comes from a higher expense in the test in a cold environment (32 kWh / 100km).

Taking into account its greater weight and higher performance, the

, with the 'ten' in emissions and a 9.7 in energy efficiency, where it also falls due to its higher cost in cold environments .

The electric

and

complete the list of the 'five stars' with this engine.

There is one more, but with hydrogen-based combustion: the

, with a considerably lower score (7.3) in the energy efficiency section.

In the

tests

, only the

and

achieved all stars.

The Toyota Prius PHEV is the only car that has achieved four stars in GreenNCAP tests.

Only one with four stars

Going back to this year, the latest tests have found only one car worthy of GreenNCAP's remarkable high or four stars: the

4x2 CVT.

This plug-in hybrid or PHEV achieves an excellent 8.3 in energy efficiency and combines this note with a 6 in 'clean air' or particle emission and with a 7 in greenhouse emissions.

A very respectful diesel

Few come close to the plug-in Prius

.

We now review those that have been rated with

, among which we find a family car with diesel engine: the

.

"The car scores highly in all three evaluation areas: 6.7 / 10 for Clean Air, 7.7 / 10 for Energy Efficiency and 4.6 / 10 for Greenhouse Gases," concludes the examiner.

The Skoda

.

.

Exceptional result of the Skoda Octavia Combi TDI: a diesel as environmentally friendly as many PHEVs.

Another car with thermal motorization, in this case of gasoline, that has achieved the notable is the

with manual gearbox.

It achieves practically the same rating as its plug-in hybrid brother, the

which emits more greenhouse gases.

A rating very similar to that of the VW Golf is obtained by another car with a gasoline engine, the

with manual

and front wheel drive.

PHEV territory

The

also get three and a half stars

A non-plug-in hybrid, the Toyota Yaris

with a 1.5-liter gasoline engine, has found its place among the elite of cars considered greener than those analyzed by GreenNCAP in 2021.
