Efficiency in cars is usually meant to be energy efficiency, energy out over energy in. And electric cars are usually more efficient by most metrics, even if you count the amount of gas an internal combustion engine uses vs the amount it takes an oil fired plant to charge an electric car that drives the same distance (well-to-wheels efficiency).
