hemi

Dome-headed engine type

Hemi is a prefix meaning half, from Greek, appearing in words like hemisphere (half a sphere) and hemiplegia (paralysis of one side of the body).

In American automotive culture, Hemi has become shorthand for a hemispherical combustion engine, a powerful V8 design where the cylinder heads have a dome shape.

Chrysler popularized the term, and a Hemi under the hood signals serious horsepower to car enthusiasts.
