The kWh is a unit of measurement. The “kWh”, or kilowatt hours, is similar to what you would see on an electricity bill – this essentially shows how much energy you have used. In the context of an electric vehicle, this refers to the battery’s capacity and will provide some indication as to the vehicle’s range.
In addition, you also have “kW” (kilowatt) which appears in the car’s description and title. This refers to the engine power. The general rule is that the more kW a car produces, the faster the car will accelerate; some car manufacturers produce the same car and specification but with different “kW”.
