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.
Tech Tip â Torque or Horsepower? The bigger the cubic inches the more power your engine is going to have. For example a 103 cubic inch engine will create more power than a 96 cubic inch motor.
