What is the Difference Between Engine Horsepower and Wheel Horsepower?

[Ella]

Here are the differences between engine horsepower and wheel horsepower: 1. Different definitions: Engine horsepower refers to the power output of the engine, while wheel horsepower refers to the horsepower at the wheels. 2. Different power levels: Engine horsepower is greater than wheel horsepower because the car's drivetrain experiences losses. Power is transmitted from the engine to the wheels through the drivetrain, and some power is lost during this transmission process. Horsepower is essentially power, which measures how much work the engine can perform per unit of time. The greater the engine's power, the higher its horsepower. 3. Different performance characteristics: Engine horsepower delivers stronger performance than wheel horsepower. Torque is another crucial performance parameter of an engine. Torque measures the output moment per work cycle. The higher the engine speed, the more work cycles the engine completes per unit of time. The greater the torque, the larger the output moment per work cycle.
