Question 1

What does the kWh/100km value mean for electric cars?

Accepted Answer

The kWh/100km value indicates how much electrical energy your EV uses per 100 kilometers. A typical value ranges between 14 and 22 kWh/100km. The lower, the more efficient the vehicle.

Question 2

How do you calculate the gasoline equivalent consumption?

Accepted Answer

You divide the kWh/100km value by the energy content of one liter of gasoline (8.9 kWh) or diesel (9.97 kWh). An EV with 18 kWh/100km corresponds to about 2.02 liters of gasoline per 100km.

Question 3

What is Wh/km and who uses it?

Accepted Answer

Wh/km (watt hours per kilometer) is an alternative unit, especially used by Tesla. To convert from Wh/km to kWh/100km, divide the value by 10. 180 Wh/km = 18 kWh/100km.
