Last Friday, my wife and I got our 2007 Jeep Wrangler X. I previously owned a 2003 Jeep Liberty Sport and my wife has owned a 2002 Jeep Wrangler Sport.
I understand that the CJ jeep apparently stood for "civilian jeep." Then, in 1987 Jeep created the first Wrangler, which was referred to as the YJ, and followed by the TJ in 1997. Now, Jeep Wranglers are referred to as JK.
Does anyone know what the initials, YJ, TJ, and JP stand for? I know that the designations refer to the separate body styles that the Jeep is built in or on. But, surely the initials refer to something or stand for something. I would appreciate it if anyone knows this and could enlighten us.
From various Internet sights, I've found the following explanations for the Jeep's history. But, no mention of JK, YJ, or TJ.
"In 1939 the U.S. Army invited proposals for a new military vehicle to replace its aging fleet of motorcycles and Ford Model T trucks. Three companies eventually responded with prototypes: Ford Motor Company, Willys-Overland, and American Bantam Car Company. The production contract was awarded to Willys in July 1941. Ford agreed to build from Willys’ plans and Bantam built trailers for the Willys vehicle.
Then, the Ford entrant in the design competition was called the “GP,” which in Ford parlance stood for “Government 80 in wheelbase Reconnaissance Car” (Willys called their design the “MB.”). “The word, ‘jeep’ came from the name of the character ‘Eugene the Jeep,’ introduced in the Popeye comic strip in 1936. The association of ‘jeep’ with the small four-wheel drive vehicle, however, wasn’t made until a few years later. The Army designated these sturdy little trucks ‘General Purpose,’ or ‘G.P.’ for short. To soldiers raised on Popeye, the transformation of ‘G.P.’ into ‘jeep’ was inevitable, and so pervasive that the Willys-Overland Motor Company trademarked the name ‘Jeep’ in 1940.
When slurred, “GP” led to the name “jeep,” which stuck to the small four-wheel-drive vehicle even though the Willys design actually won the competition and Ford ended up building the Willys design. Following World War II, public demand was so high that Willys continued producing the Jeep in tremendous numbers, re-designated as the “CJ-2A” (CJ for “civilian Jeep”). The vehicle was produced for the Army in continually improved versions until 1981, when it was replaced by the High Mobility Multipurpose Wheeled Vehicle (the “Hummer”).”
If anyone has seen or heard an explanation of these initials, I would appreciate anything you could share with me.
