According to an American study, the Tesla Model 3 would be the most energy-efficient electric car on the car market. However, these results have yet to be qualified. We explain why.
Right now, the range of electric cars is greater than ever as sales continue to rise. In August, this engine represented 12.1% of the market in Europe since the beginning of the year, an increase of 31.6% compared to 2021. A significant increase, mainly due to incentive taxes such as the ecological bonus in France, while the offer is also expanding.
More or less virtuous models
Yet there are still many discussions about whether the electric car is really a clean vehicle. In addition, according to a study by the American organization ACEEE, some electric cars pollute even more than some thermal sedans. This is especially the case with the Hummer EV due to its huge consumption and huge battery. But it depends on the country where it charges, depending on the mode of production of the electricity. So you will have understood that not all connected vehicles are created equal and some are more virtuous than others.
This is exactly what the Office of Energy Efficiency and Renewable Energy (EERE), the US agency responsible for renewable energies, was interested in. Indeed, it compared different electric models to find out which one was the most energy efficient. A total of 17 vehicles were analysed.
| Car | MPGE |
|---|---|
| Tesla model 3 | 132 |
| Clear sky | 131 |
| Tesla Model Y | 129 |
| Chevy Bolt EV | 120 |
| Hyundai Kona Electric | 120 |
| Tesla Model S | 120 |
| Kia EV6 | 117 |
| Chevrolet Bolt EUV | 115 |
| Hyundai Ioniq5 | 114 |
| Kia Niro Electric | 112 |
| Nissan leaf | 111 |
| MINI Cooper SE | 110 |
| BMW i4 Gran Coupe | 109 |
| North Star 2 | 107 |
| Volkswagen ID.4 | 107 |
| Ford Mustang Mach-E | 103 |
| Tesla Model X | 102 |
It turns out that the Tesla Model 3 comes out on top. The electric sedan then shows a score of 132 MPGe in its rear-wheel drive version. It is then followed by the Lucid Air, with 131 MPGe and the Tesla Model Y, with 129 MPGe. But what does that actually mean? Don’t worry, we’ll explain everything to you.
What is MPGe?
the MPGe is a unit of measurement created by the EPA, the United States Environmental Protection Agency. Meaning ” miles per gallon of gasoline equivalent“, it measures the energy efficiency of vehicles powered by alternative engines, such as hybrid or electric models. The MPGe is then determined by calculating the energy consumption of the vehicle. Obviously, the higher the number, the farther the car can go with the equivalent of a ” gallon » petrol (4.5 litres). Knowing that a liter of petrol contains as much energy as a battery with a capacity of 33.7 kWh.
The Tesla Model 3 can then travel the equivalent of 132 miles on 33.7 kWh, or 212 kilometers. This clearly means it’s more energy efficient than, say, a Model X, which displays an MPGe of just 102.
Eligibility results
But be careful, because if these results give us an interesting sequence of ideas, they should be nuanced for Europe. There is no French vehicle in this classification, and it would have been interesting to see lighter electric cars emerge, potentially consuming less than the Tesla Model 3. However, there are the Kia Niro Electric and the Hyundai Kona Electric that lag behind the Tesla. More efficient than the Model 3 is currently hard to find.
However, this data was produced using the US EPA Certification Cycle, which differs from our European WLTP. It is therefore closer to reality than the autonomy announced in Europe.
