Electric propulsion is generally 4x to 6x cheaper per kilometer than conventional petrol combustion engines.
Mathematical Formula & Physical Model
Energy consumption per kilometer is multiplied by your electricity tariff to project running costs across customizable driving periods.
1
Energy Consumption (kWh/km) = 1 / Efficiency (km/kWh) 2
Cost per Kilometer = Energy Consumption (kWh/km) × Electricity Rate 3
Period Expense = Cost per Kilometer × Commute Distance Worked Example

Frequently Asked Questions
How does driving speed affect EV running costs?
Aerodynamic drag scales quadratically with speed. Driving at 110 km/h consumes approximately 25% to 35% more energy per kilometer compared to cruising at 70 km/h, directly increasing running costs.
How do climate control systems influence per-km cost?
Cabin air conditioning and heating draw power directly from the high-voltage traction pack, reducing real-world efficiency by 10% to 20% during extreme weather.
