Horsepower is the measure of a car engine’s performance. One horsepower is equivalent to the energy required to complete 33,000 foot-pounds of work per minute. James Watt, an 18th-century engineer, discovered the measurement after observing horses operate a mine pump driven by gears. Many centuries later, automobile manufacturers still use horsepower (HP) to calculate the vehicle engine's ability.

According to James Watt, one horse can lift 22,000 lbs over one foot in a minute. Multiplying 22,000 lbs gives you the value of a horsepower-33,000 lbs over one foot per minute. Car engines have different horsepower levels at different times. For example, an auto with a 300 HP engine tells you how the particular car performs on the road. However, the performance can depend on stroke, engine bore, compression ratio, exhaust design, and camshaft profile.
