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.
If we use a 40% efficient non-combined cycle coal power plant for example, the electric car actually has lower efficiency from coal to wheel vs. the gasoline car from tank to wheel. However gasoline is an expensive, high quality fuel which costs many times more per unit energy than natural gas, coal, nuclear power, etc. which is why an electric car is far cheaper to run as far as fuel goes.
