An IC engine is 20-30% efficient depending on the technology (the rest is waste heat). An electric engine is 80-90%. Even if you imagine the electricity comes from a gasoline power plant, the efficiency at the plant will be higher than a regular car ICE because of scale benefits + use of a cold sink (ocean/river).
