Horsepower

Horsepower is the customary unit for measuring the power of an engine. By definition, one horsepower is the power needed to lift 33,000 pounds a distance of one foot in one minute.
The horsepower rating of an engine gives an indication of how strong the engine is. However, other factors, such as the weight of the vehicle, affect how useful the horsepower will be. The more a vehicle weighs, the more horsepower is needed to move it.
