What does car torque mean and what is its function?

Car torque is specifically described as follows: 1. Meaning of car torque: Car torque refers to the moment of force output by the engine from the crankshaft end. Under fixed power conditions, it is inversely proportional to the engine speed—the faster the speed, the smaller the torque, and vice versa, reflecting the vehicle's load capacity within a certain range. 2. Function of car torque: The piston's reciprocating motion in the cylinder does a certain amount of work per cycle, measured in Newton. The work done per unit distance is torque. Torque is an important standard for measuring the quality of a car engine, and the torque of a vehicle is directly proportional to the engine's power.
Torque is the rotational force of the engine, somewhat like the pushing force when you shove something. Having driven for several years, I've noticed that cars with higher torque accelerate remarkably fast at startup—just stepping on the gas pedal makes you feel that thrust pushing you forward. Its primary role is to enhance acceleration performance, especially during stop-and-go at traffic lights or when climbing hills, preventing the car from feeling sluggish. In daily driving, a car with good torque responds more swiftly and handles congested traffic much smoother, unlike low-torque vehicles that require stomping on the gas to keep up with the flow. Another advantage is stronger towing capacity, making it effortless to pull a small trailer or carry heavy loads. In short, torque impacts both the thrill and practicality of driving, which is why I prioritize this parameter when choosing a car.
Torque is the rotational force output by the engine. To put it simply, it determines whether the wheels can rotate with power. In terms of function, it directly affects the car's acceleration capability and climbing performance. When torque is high, the car can deliver power even at low speeds, making overtaking or starting off quick and effortless. Unlike horsepower, which mainly shows its strength at high speeds, torque makes daily driving more worry-free, such as avoiding engine strain on steep slopes. High-torque engines can also reduce fuel consumption because you don't need to rely on high RPMs to compensate for power. As someone who enjoys studying cars, I believe torque is a core engine metric—ignoring it might make driving less enjoyable.
