What is the Difference Between Horsepower and Torque?

[LeStephen]

Horsepower and torque differ in the following ways: 1. Different measurement indicators: Horsepower measures how much work an engine can perform per unit of time; torque measures the amount of rotational force the engine can output in a single work cycle. 2. Different functional representations: Higher horsepower results in a higher top speed; greater torque provides stronger instantaneous acceleration. Power and torque are two critical performance parameters of an engine, and many consumers prioritize these when purchasing a vehicle. Power is related to torque and RPM—higher RPM and greater torque result in higher engine power. An engine with higher RPM performs more work cycles per unit of time, while an engine with greater torque can output more rotational force in each work cycle.
