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.
Motor efficiency is the ratio between the amount of mechanical work the motor performs and the electrical power it consumes to do the work, represented by a percentage. A higher percentage represents a more efficient motor. Electric motor efficiency is dependent on (but not limited to) design, materials, construction, rating, load, power quality, and operating conditions.
