Why did it called jeep?

Nowadays, jeep means an old 4-wheel drive vehicle. Many country use it as a term of language to determine GPV (General Purpose Vehicle), and because of that many encyclopedia editor, book author, and others refer jeep as General purpose. So what's Jeep realy stand for?

            Many has been explain about the name origin of jeep, all of which have proven difficult to verify. Acctually it's mentioning the 1941 ford GPW, and the abbreviation for GP for the Ford production code. Letters where used at Ford differentiate between different models with different horse power rating, wheelbase measurement, ect. “G” was used by Ford to differentiate between vehicles produced for government and for civilian ued. And the followed letter “P” just happened to land at the “80 inch wheelbase” which is the wheelbase of the jeep.”W” indicates its Willys-overland engine, on wich the GPW were based.

            So how did it get to be called jeep anyway? Basicly it was a phonetically slurred from the GP code model into the word Jeep. In late 1930s/early 1940s, a character named Eugene The Jeep showed up in The Popeye Comic Strip. It was Popeye's jungle pet and was small,able to move between dimensions and could solve seemingly impossible problems. Then at the time of World War II, the soldiers were impressed with the new vehicle that informally named after it.

            Early in 1942, Willys-Overland demonstrated the vehicle's off-road capability by having it drive up the steps of the United State Capitol, driven by Willys test driver Irving "Red" Haussman, who had recently heard soldiers at Fort Holabird calling it a "jeep." When asked by syndicated columnist Katherine Hillyer for the Washington Daily News, what it was called, Irving answered, "It's a jeep”.

            Even it was a military slang for the vehicle, this exposure caused all other jeep references to fade, leaving the 4x4 with the name.
