What is the difference between 150 and 140 torque?
2 Answers
Torque 150 accelerates faster than torque 140. Definition of torque: Torque refers to the average moment of force output from the crankshaft end when the engine is running, commonly known as the engine's "rotational force." It is an important parameter of engine performance. The greater the torque, the more "force" the engine outputs, the faster the crankshaft speed changes, and the better the car's climbing ability, starting speed, and acceleration. The difference between torque and horsepower: They have different meanings. Torque refers to the force that twists an object and causes it to deform, producing a moment when the object is subjected to a tangential force in the direction of rotation. Horsepower is a unit commonly used in engineering to measure power and is a physical quantity that determines a car's top speed. They have different units: torque is measured in Newton-meters, while horsepower is measured in kilowatts. Higher horsepower results in a higher top speed, while higher torque results in greater instantaneous acceleration force. For example, commercial vehicles have very high torque output values, so they have strong instantaneous acceleration force in low-speed ranges, but their weakness is relatively low horsepower output, meaning their top speed is lower.
I've driven quite a few cars, and the 10Nm difference between 150Nm and 140Nm torque has limited impact in daily life. When starting or climbing hills, 150Nm might feel slightly more responsive at takeoff, especially in urban areas with frequent traffic lights, providing quicker acceleration and reducing lag. However, vehicle weight plays a crucial role—the difference is less noticeable in lighter cars, while even 140Nm can handle most slopes in heavier SUVs. For most commuters, like office workers picking up kids, this difference is almost negligible. Engine tuning and transmission coordination matter more—for instance, with optimized CVT transmissions, 140Nm can still deliver smooth driving. Overall, ordinary drivers needn't overthink it unless they're performance enthusiasts. Safety first—maintaining reasonable speeds is what truly counts.
