Electric motors are in general, a lot more efficient that internal combustion engines. An average combustion engine has about 18â20%. A formula one engine, has about 50% of an efficiency.
While the motor can be 85 to 95% efficient, once the power goes through the inverter, battery, and charger, EV efficiency is closer to 70%. However, electric engines and batteries can be relatively sensitive to hilly terrain, and temperature changes that could reduce the efficiency even father.
