Joke answer: Style

Real answer: Horsepower originates from the potential sustained work of a (more-or-less) average horse of the 18th century. A horse at full speed is outputting more-than-one-horsepower - at a gallop, they're outputting 10 horsepower or more.

Hmm .. style over substance ๐Ÿ˜‡

I just went down a rabbit hole as a result of your reply. Thank you!

The horsepower was defined by James Watt as a way to compare his steam engines against draft horses. The unit of power in use today is Watt and is named after him.

For a giggle, if you're into SI units, look at the definition of a horsepower.
