What does maximum horsepower ps mean?

[RowanDella]

Maximum horsepower ps refers to the maximum power output that a vehicle can achieve, with horsepower measured in ps, similar to the maximum power data. Power is defined as the work done by an object per unit time. The greater the power, the higher the rotational speed, and consequently, the higher the maximum speed of the car. Since effective power is proportional to mean effective pressure, rotational speed, and displacement, it can also be equated to the product of effective torque and rotational speed. Displacement is constant, while mean effective pressure can increase with higher rotational speeds. When peak effective torque is reached, horsepower growth slows down. Only when the product of effective torque and rotational speed is maximized does it represent the value of maximum horsepower.
