Understanding cost per kilometre
Electric vs combustion: the real gap
Charging an electric vehicle at home (€0,21/kWh off-peak) costs about €3,15 per 100 km for a WLTP consumption of 15 kWh/100 km. An equivalent petrol vehicle consuming 6.5 L/100 km at €1,99/L costs €12,94 — 4.1 times more. This gap narrows to 2× on rapid DC charging (€0,45/kWh).
The impact of charging type
The cost of an electric trip varies threefold depending on the charging method. Home: €0,21/kWh (off-peak). Public AC: €0,30/kWh. Motorway rapid DC: €0,45/kWh. For a 300 km trip at 16 kWh/100 km, the bill ranges from €10,08 (home) to €21,60 (rapid DC).
How to read our results
Our results show the trip cost in euros, cost per 100 km and WLTP combined consumption. The cheapest vehicle for energy is highlighted in green. You can adjust the distance (10 to 1,000 km) and charging rate (home, AC, DC) to simulate your real usage. Consumption data comes from manufacturer specification sheets (WLTP standard).
