I released Horsepower on October 14, 1996, as a display typeface. It was a variation of my earlier Induction design, both of which drew from Wim Crouwel’s 1967 New Alphabet. New Alphabet had eliminated diagonals and curves in favor of horizontal and vertical strokes, reflecting the limitations of display technology at the time. Induction softened that approach slightly, and with Horsepower I tried to make it even more accessible by narrowing the width, using more conventional letterforms, and adding lowercase. The name tied to ideas of speed and technology rather than any specific subject matter.

On July 20, 2021, I released an update. I corrected inconsistencies, revised kerning and accents, expanded language support, and improved fractions. I also increased the character size by 13 percent to address cross-browser compatibility; this was a technical fix rather than a stylistic refinement.

Horsepower did not see notable use in published work, but it remained an experiment in balancing the aesthetics of 1960s typographic futurism with more practical letterforms. On November 2022, I placed it into the public domain.
