Mobility: Here are the ten greenest electric cars

Published

Electric vehicles are undoubtedly more environmentally friendly than petrol or diesel ones. However, there are also big differences in the electric car category. A new Transport and Environment Association (ATE) website highlights them – and may lead to explanations from some manufacturers.

1 – Dacia Spring
Type: SUV, power: 33 kW, average consumption: 13.9 kWh/100 km, range: 230 km, price: 18,900 francs, energy costs: 2,780 francs.

today there is no no need to procrastinate anymore on the fact that electric cars are more climate-friendly than petrol or diesel ones. Throughout their entire lifespan, electric vehicles have a CO2 balancetwo twice as good as models that use fossil fuels.

But what about environmental performance within the same category? What are the greenest electric models? And while we’re at it, what are the differences between hybrid, gasoline-powered and diesel-powered vehicles?

Battery size determines emissions

The website Eco-auto.info from the Transport and Environment Association (ATE) answers these questions. It provides information on the ecological impact of passenger cars and commercial vehicles.

Three criteria are evaluated for electric cars: CO emissionstwo, the load related to battery production and the noise generated while driving. Hybrid cars receive two values ​​of COtwo: one for the combustion engine, one for the electric mode. As for fossil vehicles, the focus is on energy efficiency and environmental impact.

But back to electric vehicles. CO valuetwo while driving is calculated based on electricity consumption and overall CO emissionstwo of the Swiss standard electricity mix. As imported electricity always contains a part of coal-fired electricity, CO emissionstwo therefore, they are not zero. On the other hand, if we just filled ourselves with green electricity, they would.

The same is not true of battery manufacturing: this consumes a lot of energy and leads to CO emissions.two relatively high. And the bigger the battery, the bigger the CO emissionstwo are important. Compared to fossil models, electric cars are even more environmentally friendly: after having driven an average of 30,000 kilometers they generally have a better CO balancetwo and are therefore more environmentally friendly, as revealed in the Confederation’s online guide entitled “Electric tour”.

The heavier the vehicle, the worse the value.

However, the battery is not the only element to take into account in the energy efficiency of electric cars. We know that the heavier and more powerful the car, the greater its energy consumption. First in the ranking, the Dacia Spring, which has a power output of just 33 kilowatts for an empty weight of 1,000 kilograms, consumes an average of 13.9 kilowatt-hours per 100 kilometers, while the Porsche Taycan CT 4S, 360 kilowatts of power and a brake weight of 2,320 kilos, “engulfs” almost twice that, or 27.4 kilowatt-hours, which puts it in last place.

Among the top ten in the ranking, power is limited, but so is autonomy. Only the Hyundai Kona Electric, in fourth position, exceeds 300 kilometers. So there are improvements to be made. Another important parameter speaks in favor of electric: energy costs. For the first in the classification of the electric car category, they reach 2,780 francs per 100,000 kilometers, while for the red lantern they are almost double, ie 5,480 francs.

The list proposed by ATE, however, has a defect: some of the models mentioned are no longer built and are not always available, or with difficulty.
