Comparing the real-world energy efficiency of the most efficient electric cars

Aat de Kwaasteniet, one of our readers, has made great strides in comparing the actual power consumption of various electric vehicles with other factors. Comparing the 66 EV models with the real-world energy efficiency of the most efficient and minimalist electric cars is a standardized and most scientifically designed analysis.

The analysis focuses on models in Europe and models used in Europe, but the comparisons can certainly be useful beyond the old continent, and are really interesting!

Aat writes, “I set up a spreadsheet on EVs to record the actual power consumption of EVs. To do this, I searched the Internet and YouTube, recorded all the EVs videos, and recorded the power consumption according to temperature and speed. Then I normalized the power consumption so that they can be compared. I have implemented energy allocation. So far not all EVs have a power label but there are big differences between them. I have now clarified it through this spreadsheet. Charging speed is also recorded. The reader can now see the average speed of long trips and so on.

EVA details and real-world data

Various details about the tests are included in the comparison sheet as well as vehicle details.

  • Battery capacity (kWh)
  • WLTP range (km)
  • WLTP usage (g / km) recommended by the manufacturer
  • Manufacturer Indicates Maximum DC Charger (kW)
  • Measured maximum DC charging power (kW)
  • Payment time 10-80% per minute
  • Charging at 10-80% per kWh
  • Average charger 10-80% (kW)
  • Average Fast Charging Power 10-80% Per 1 Charge (km)
  • Price in the Netherlands

… More.

Needless to say, you can spend hours reviewing the details of this spreadsheet.

The most effective electric cars

At the end of the day, AAT proved to be a real scientist, normalizing electricity consumption based on a temperature of 10 degrees Celsius (average in the Netherlands). This cell back filling is one of the two columns in red (column N), and the sheet is sorted according to the result in this column. Basically, here is the answer to the question: Which are the most energy efficient electric cars in Europe and which electric cars use the power per kilometer?

You can see that the four models above are the most energy efficient and the only ones that get the “A” power rating are:

  • VW e-Up 36.8 kWh – 136 Wh / km
  • VW E-Golf 35.8 kW – 149 W / km
  • Hyundai Ioniq 38 kWh – 150 Wh / km
  • Tesla Model 3 LR 82kWh – 152 Wh / km

At the other end of the scale, here are the five models with the worst results.

  • Volvo XC40 – 256 W / km
  • BMW iX xDrive 40 – 256 Wh / km
  • Audi E-Tron 50 – 260 W / km
  • Audi e-tron S 55 Quattro – 266 W / km
  • BMW i4 M50 – 268 W / km

These 5 out of 16 models have a “G” power rating. (As far as I know, I thought “F” was the lowest.)

Thanks and thanks for doing the job! Jump to the table and see what you notice. Naturally, the focus is on real-world EV energy consumption per kilometer, but there is a lot of data to compare models in different ways and they can increase your demand.
