Best Answer: Torque is a twisting force. It is the power output of an engine at one specific point in time. The first number, 200 in your expample, is the amount of torque. In America is is measured in foot/pounds. The second number, 400 in your example, is the RPM where that torque number occurs.
, I'm the editor of AccurateAutoAdvice.com. In physics, torque is defined as the ability to do work, or apply force to move an object.. (NOTE: Not strict definitions, just how I would explain it) In practical automotive terms, torque is a measurement of an engine's ability to turn the wheels at any given RPM. A higher torque rating is a good indicator of acceleration ability, especially when that torque rating is available at a low RPM.
