Stop guessing. Calculate the truth about your car.
Fuel is only 30% of the cost. Depreciation, maintenance, and insurance consume the rest. Find out where your money really goes.
Same road. 3x more energy.
A liter of petrol is ~9.3 kWh of energy. An ICE SUV uses as much energy for 100 km as an EV for 350 km. The difference? Engine efficiency.
per 100 km (6.4 L × 9.3 kWh/L)
Efficiency: ~41% (Atkinson cycle) • Cost per 100 km: 41,60 zł
per 100 km (directly from battery)
Efficiency: ~77% (plug-to-wheel) • Cost per 100 km: 11,31 zł
The RAV4 Hybrid needs 60 kWh of fuel — even with an efficient Atkinson cycle (41%) wastes 36 kWh as heat. Tesla draws 17 kWh from the battery and loses only 4 kWh.
