What does torque measure in an engine?

Torque measures the amount of rotational force produced by an engine. This force is crucial because it directly affects the vehicle's ability to perform tasks such as accelerating, towing, or hauling heavy loads. Essentially, torque is what gets the vehicle moving from a standstill and is vital for providing the necessary power to overcome obstacles and inclines.

While speed, weight, and fuel efficiency are important metrics in vehicle performance, they do not accurately describe what torque represents. Speed refers to how fast the vehicle is traveling, weight pertains to the mass of the vehicle, and fuel efficiency relates to how effectively the engine uses fuel. Torque, in contrast, is fundamentally about the force applied at a rotational level, making it a key player in engine dynamics and vehicle capability.
