What Does Maximum Horsepower of a Car Mean?

[WalkerRose]

Maximum horsepower of a car refers to the maximum power output that the 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 the mean effective pressure, rotational speed, and displacement, it can also be equated to the product of effective torque and rotational speed. Displacement is fixed, while the mean effective pressure can increase with rising rotational speed. When peak effective torque is reached, the growth in horsepower slows down. Only when the product of effective torque and rotational speed is maximized does it represent the value of maximum horsepower.
