Summary
  • The Jeep brand received exclusive rights to use its name on June 13, 1950, 7 years after Willys-Overland applied for the trademark.
  • There are several theories surrounding the origin of the word “jeep,” but its use dates as far back as World War I when military personnel used it to refer to unproven human recruits or unproven new vehicles.
  • Jeep might have also come from the acronym “GP,” an acronym for general purpose vehicles.

When we think of jeeps, we often think of the durable off-roaders produced by the American automobile brand Jeep. Some people even view the jeep and Jeep as one and the same. Contrary to popular belief, however, these two words aren’t actually synonymous. In fact, back then, the word “jeep” used to mean something different.

How Did Jeep Get Its Name?

In June 1940, the US military needed a new reconnaissance vehicle. It had to have a wheelbase less than 75 inches long and less than 36 inches tall. This original car should feature a two-speed transfer case, a folding windshield, and three bucket seats. Above all, it must be a four-wheel drive capable of driving off-road, so military personnel could easily transport people and cargo between bases.

At the time, 3 manufacturers submitted their prototypes: Willys-Overland, American Bantam, and Ford. Willys-Overland’s vice president of engineering designed and submitted the Willys Quad. While each brand received approval to produce 70 vehicles for testing, none of them met the military’s prescribed weight limit.

With further improvements, the Willys Quad eventually evolved into the Willys MB, which became the new vehicle of military personnel. Soon after, Willys-Overland released the Jeep CJ-2A, the first civilian Jeep to hit the market.

In 1943, Willys-Overland applied for the “Jeep” trademark, but conflict over the exact origins of the name made approval difficult. It wasn’t until June 13, 1950 that the trademark was granted, giving Willys exclusive rights to use the moniker that has since become a household name in the automobile industry.

Jeep: What Does It Stand For?

According to many, the history of the Jeep brand and the origin of the word “jeep” aren’t the same. You’ll find several theories attempting to answer what the jeep’s origin is, such as the following:

Military Slang

The word “jeep” was already used by military personnel as far back as World War I. At the time, however, it didn’t exactly refer to a 4×4 off-road vehicle. Military personnel would use this word to describe an unproven human recruit or a dubious new vehicle.

Later on, they also used “jeep” to refer to any small plane, helicopter, or gadget, which was described in the military dictionary “Words of the Fighting Forces.”

GP Vehicle

According to some, the word “jeep” originated from Ford’s early military jeep models. Military personnel would use the acronym GP to refer to general purpose vehicles. Because they sounded similar, some speculated that the word “jeep” was derived from GP.

Others believe that the “G” in the acronym actually stood for government, while the “P” referred to a reconnaissance car with an 80-inch wheelbase.

Popeye and Eugene the Jeep

Another popular theory of the origin of the word “jeep” can be found in the “Popeye the Sailor” comic strip published in March 1936 by E.C. Segar. The comic introduced Eugene the Jeep for the first time.

However, Eugene the Jeep in the cartoon isn’t a vehicle. He’s actually a magical yellow creature with a charismatic personality. After his debut, fans began using the word “jeep” to describe something as extraordinary as Eugene. His popularity among readers led people to believe that his name influenced the name of the Jeep brand.

Just Enough Essential Parts

While this particular theory seems less likely, there are Jeep owners who like to claim that JEEP stands for “Just Enough Essential Parts.” It refers to the consistent reliability of Jeep models, including the standard trims.

Just Empty Every Pocket

For some, JEEP is an acronym for “Just Empty Every Pocket.” It’s a popular acronym among Jeep owners because of the high costs of maintaining their vehicles. Jeep modifications also tend to be expensive, which is why people often joke about how they have to spend all their money and empty their pockets.

The Jeep Brand

Today, when people hear the word “jeep,” the Jeep brand first comes to mind. Jeep is a division of the Chrysler group that specifically makes sport utility vehicles SUVs, off-road vehicles, and pickup trucks.

While it’s mostly known for producing off-roaders, Jeep has also released luxury SUVs. Today, it’s a well-trusted brand among customers for consistently producing safe, reliable, and powerful vehicles over the years.
