5. No one really knows how the name Jeep came to be
While it’s commonly thought that “jeep” is a truncation of General Purpose vehicle, or GP, that’s likely wrong. Ford’s version was officially named GPW, where G means Government, P refers to the distance between the wheels (80 inches), and W stands for Willys, since the vehicles Ford produced were technically under license from Willys.
Alternately, some say it was common lingo to refer to all military prototypes as “jeeps,” and that “peeps” even entered the lexicon briefly. All we know is...maybe?
