Torque is a measure of the twisting force generated by the engine’s crankshaft. The transmission and final drive (differential) are used to multiply the torque output of the
engine. The amount of torque an engine generates, calculated in “foot-pounds,” is an indication of how effectively it can generate its power. Different engines develop their peak torque at different rpm levels. Therefore it is important to recognize the level at which a given engine develops its peak torque.
• Engines that develop peak torque at low rpm are more responsive at lower rpm, but will “run out of steam” as rpm increase.
• Engines that develop peak torque at high rpm will be very responsive at high rpm, but will react slowly at low speeds.
