The origin of the term "jeep" Edit

There are many stories about where the name "jeep" came from. These, although they make for interesting and memorable stories, are not quite accurate.

-Probably the most popular notion has it that the vehicle bore the designation "GP" (for "General Purpose"), which was phonetically slurred into the word jeep. R. Lee Ermey, on his television series Mail Call, disputes this, saying that the vehicle was designed for specific duties, was never referred to as "General Purpose," and that the name may have been derived from Ford's nomenclature referring to the vehicle as GP (G for government-use, and P to designate its 80-inch-wheelbase). "General purpose" does appear in connection with the vehicle in the WW2 TM 9-803 manual, which describes the vehicle as "... a general purpose, personnel, or cargo carrier especially adaptable for reconnaissance or command, and designated as ¼-ton 4x4 Truck", and the vehicle is designated a "GP" in TM 9-2800, Standard Military Motor Vehicles, 1 September 1943, but whether the average jeep-driving GI would have been familiar with either of these manuals is open to debate.

This version of the story may be complicated by the name of another series of vehicles with the GP designation. The Electro-Motive Division of General Motors, a maker of railroad locomotives, introduced its "General Purpose" line in 1949, using the GP tag. These locomotives are commonly referred to as Geeps, pronounced the same way as "Jeep".

-Many, including Ermey, claim that the likelier origin refers to the character Eugene the Jeep in the Thimble Theater (Popeye) comic strip. Eugene the Jeep was dog-like and could walk through walls and ceilings, climb trees, fly, and just about go anywhere it wanted; it is thought that soldiers at the time were so impressed with the new vehicle's versatility that they informally named it after the character. The character "Eugene the Jeep" was created in 1936.

-The term "jeep" was first commonly used during World War I (1914-1918) by soldiers as a slang word for new recruits and for new unproven vehicles. This is according to a history of the vehicle for an issue of the U.S. Army magazine, Quartermaster Review, which was written by Maj. E. P. Hogan. He went on to say that the slang word "jeep" had these definitions as late as the start of World War II.

"Jeep" had been used as the name of a small tractor made by Modine.

The term "jeep" would eventually be used as slang to refer to an airplane, a tractor used for hauling heavy equipment, and an autogyro. When the first models of the jeep came to Camp Holabird for tests, the vehicle did not have a name yet. Therefore the soldiers on the test project called it a jeep. Civilian engineers and test drivers who were at the camp during this time were not aware of the military slang term. They most likely were familiar with the character Eugene the Jeep and thought that Eugene was the origin of the name. The vehicle had many other nicknames at this time such as Peep and Pygmy and Blitz-Buggy, although because of the Eugene association, Jeep stuck in people's minds better than any other term.

Words of the Fighting Forces by Clinton A. Sanders, a dictionary of military slang, published in 1942, in the library at The Pentagon gives this definition:

"Jeep: A four-wheel drive car of one-half to one-and-one-half ton capacity for reconnaissance or other army duty. A term applied to the bantam-cars, and occasionally to other motor vehicles (U.S.A.) in the Air Corps, the Link Trainer; in the armored forces, the ½ ton command car. Also referred to as "any small plane, helicopter, or gadget."

Early in 1941, Willys-Overland demonstrated the vehicle's ability by having it drive up the U.S. Capitol steps, driven by Willy's 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 (or by a bystander, according to another account) what it was called, Irving answered "It's a jeep."

Katherine Hillyer's article was published on 20 February 1941 around the nation and included a picture of the vehicle with the caption:

"LAWMAKERS TAKE A RIDE- With Senator Meade, of New York, at the wheel, and Representative Thomas, of New Jersey, sitting beside him, one of the Army's new scout cars, known as "jeeps" or "quads," climbs up the Capitol steps in a demonstration yesterday. Soldiers in the rear seat for gunners were unperturbed. "

This exposure caused all other jeep references to fade, leaving the 4x4 truck with the name.

Willys-Overland Inc. was later awarded the sole privilege of owning the name "Jeep" as registered trademark, by extension, merely because it originally had offered the most powerful engine.

The Jeep Marque Edit

A division of Chrysler LLC, the most recent successor company to Willys, now holds trademark status on the word "Jeep" and the distinctive 7-slot front grille design. The original 9-slot grille associated with all WW2 jeeps was designed by Ford for their GPW, and because it weighed less than the original "Slat Grille" of Willys, (an arrangement of flat bars) was incorporated into the "Standardized jeep" design.

The marque has gone through many owners, starting in 1941 with Willys, which produced the first Civilian Jeep (CJ). Willys was sold to Kaiser in 1953, which became Kaiser-Jeep in 1963. American Motors Corporation (AMC) purchased Kaiser’s money-losing Jeep operations in 1970. The utility vehicles complemented AMC’s passenger car business by sharing components, achieving volume efficiencies, as well as capitalizing on Jeep’s international and government markets. The Chrysler Corporation bought out AMC in 1987, shortly after the Jeep CJ was replaced with the AMC-designed Jeep Wrangler or YJ. Chrysler merged with Daimler-Benz in 1998 to form DaimlerChrysler and was split from Daimler less than 10 years later. Presently, Jeep is a division of privately held Chrysler LLC.

American Motors Corporation set up the first automobile-manufacturing joint venture in the People's Republic of China on January 15, 1984. The result was Beijing Jeep Corporation, Ltd., in partnership with Beijing Automobile Industry Corporation, to produce the Jeep Cherokee (XJ) in Beijing. Manufacture continued after Chrysler's buyout of AMC. This joint venture is now part of DaimlerChrysler and DaimlerChrysler China Invest Corporation. The current model is the Jeep 2500, an updated XJ Cherokee.

Jeep vehicles have "model designations" in addition to their common names. Nearly every civilian Jeep has a 'xJ' designation, though not all are as well-known as the classic CJ. The current model departed from the xJ format and is designated 'JK'

Military Requirements Edit

The public tender The need for a go anywhere reconnaissance vehicle was being felt by the Army since World War I and this promoted the appearance of several proposals over the years. After several tentative versions the specifications laid down by the Quartermaster Corps, on July 7, 1940, called for:

1. A driving front axle with 2-speed transfer case including provisions for disengaging the front axle drive. 2. A body of rectangular design with afolding windshield and 3 bucket seats. 3. Increased engine power (presumably in respect to the Belly-flopper prototype). 4. Means for towing. 5. 30-caliber machine gun mount. 6. Blackout lighting. 7. Oil-bath air cleaner. 8. Hydraulic brakes. 9. Full floating axles. 10. Wheelbase of 80". 11. Maximum height of 40". 12. Maximum weight of 1275 lbs. 13. Approach and departure angles of 45 and 40 degrees, respectively. 14. Must reach 50 mph on hard surface. 15. Special bracing for a pintle hook setup. 16. No aluminium to be used for cylinder head. 17. At least 4 cylinders. 18. 8 of the 70 vehicles made had to be four-wheel-steer.

The invitation to submit bids was sent to 135 U.S. automobile manufacturers to produce 70 vehicles; the small Bantam company managed to meet the deadline delivering the pilot model in September 23 1940. Although it was 730 lbs. overweight it was judged good. Willys-Overland submitted crude sketches of their vehicle and underbid Bantam, although they could not meet the 75 day delivery period; after adding penalties for this the Bantam proposal was lower and this company received an order to produce 70 Model 60 or MKII.

Willys Overland submited two units of its pilot model, the Quad, in November 11; this had many of the features from the Bantam as did another prototype from Ford, who delivered two of its Pigmy in November 23. Both Willys-Overland and Ford were given free access to Bantam's prototype and blueprints, which goes a long way to explain the similarities.

With all three prototypes satisfactory, the Army decided to order 1500 of each for field evaluation, with deliveries to begin in early 1941; each of the prototypes would suffer alterations to remedy deficiencies brought out by the testing. The modified versions were the Bantam 40 BRC, the Willys MA and the Ford GP (G for Government, P for 80" wheelbase).

In July 1941 the War Department decided to adopt one single model; Willys was selected because it bid lower than the others but the MA had to be redesigned in view of the experience gained with the tests. The redesigned model was named MB by Willys but the contracts to manufacture the vehicle went both to Willys and Ford, where it was named GPW (the W was added to refer to the Willys motor). Meanwhile, about 1000 Bantam 40 BRCs were built for the Russian Army.
