The relationship between power and torque is: power is the product of torque and speed. If the speed is constant, the greater the power, the greater the torque. Power and torque belong to the performance of a car. Power refers to the work done by an object per unit time. The maximum power is used to describe the dynamic performance of the car. The maximum power is expressed in kilowatts.

Power is the amount of energy output in one second, or the force multiplied by the distance in the direction of the force; torque is the product of the output force and the distance in the vertical direction of the force. Torque affects speed, and power affects speed.

Power refers to the work done by an object per unit time. It is a physical quantity that expresses how quickly an object does work. The greater the power, the higher the speed, and the higher the maximum speed of the car. Maximum power is often used to describe the dynamic performance of the car. Maximum power is generally expressed in metric horsepower (PS) or kilowatts (kW).

Torque is the force that causes an object to rotate. In physics, it is the magnitude of the moment, which is equal to the product of the force and the moment arm. The international unit is Newton-meter N.m.

Torque refers to the average torque output from the crankshaft end when the engine is running. It is an important parameter of engine performance. It reflects the load capacity of the car within a certain range. Under the condition of fixed power, it is inversely proportional to the engine speed. The faster the speed, the smaller the torque, and vice versa. The greater the torque, the greater the "power" the engine outputs, the faster the crankshaft speed changes, and the better the car's climbing ability and acceleration
