What is the difference between power and horsepower?
1 Answers
Power and horsepower mainly differ in meaning. Power refers to the comprehensive index of a car, while horsepower primarily indicates the engine's capability. Here are the relevant details: 1. Power performance: Automotive power performance refers to the average driving speed a car can achieve on a good road under the influence of longitudinal external forces, which is one of the fundamental performances of a car. The resistances encountered during driving include rolling resistance, air resistance, gradient resistance, and acceleration resistance. 2. Horsepower: Horsepower is a commonly used unit of measurement for power in engineering. 1 horsepower equals the work done to lift 75 kilogram-force·meters in 1 second, also equivalent to 0.735 kilowatts, or known as metric horsepower.
