It is an imperial unit of engine power, that quantifies work performed over time. Originally, it measured steam engine output against draft horses, later applied to various engines, electric motors, turbines, and machinery.

Horsepower (hp) = 745.7 Watts

What is the History Behind the Term Horsepower?

The term horsepower was introduced by James Watt, a Scottish inventor who made significant advancements in steam engine technology, though he is often incorrectly attributed as its inventor. Watt’s path to coining this word involved mathematical calculations, careful observations, and a touch of clever marketing.

In 1776, Watt revolutionized existing steam engine designs, greatly enhancing their performance and fuel efficiency (they primarily used coal). To showcase the superiority of his engines to a market that still relied heavily on horses, Watt devised a brilliant idea. He decided to demonstrate how much more efficient his engines were compared to horse-powered machinery like grain mills.

It’s noteworthy that the same invention that heralded the Industrial Revolution also gave birth to a term that remains in common use today.

Why is Horsepower Important for Car Buyers?

It is a crucial factor for buyers to assess as it directly impacts the car’s performance. In a vehicle, an engine with higher horsepower and torque ensures quicker acceleration, particularly valuable for those using highway on-ramps frequently, and provides enhanced towing capabilities. Conversely, a lower-horsepower engine in the same vehicle prioritizes fuel efficiency over rapid acceleration.
