Willys Hurricane engine and had an wheelbase. The CJ-4 body tub was an intermediate design between the straightforward raised hood from the CJ-3B and the all new curved body style of the CJ-5. The design was rejected and the vehicle was eventually sold to a factory employee. Evidence has surfaced, that derived prototypes called CJ-4M and CJ-4MA (XM170) have also been seriously considered, as precursors to the 1951 M38A1 and M170 military Jeeps. Although the CJ-4M prototype may not have been actually built, the stretched wheelbase ambulance prototype with registration "CJ-4MA-01" turned up in 2005. CJ-3B The Willys CJ-3B replaced the CJ-3A in 1953, the same year Willys-Overland was bought by Kaiser Motors. The Kaiser parent company removed "Overland" from the Willys Motors subcompany name. The CJ-3B introduced a higher grille and hood to clear the new Willys Hurricane engine. A four-speed manual transmission became optional in 1963, at an extra cost of $194. The turning radius was . Until 1968, about 196,000 CJ-3Bs were produced, of which 155,494 were assembled in the U.S. The CJ-3B was turned into the M606 military jeep (mostly used for export, through 1968) by equipping it with commercially available heavy-duty options, such as larger tires and springs, and by adding black-out lighting, olive drab paint, and a trailer hitch. Shipments of the M606 militarized version of the Jeep CJ-3B, exported for military aid under the Mutual Defense Assistance Program, accounted for a substantial percentage of the limited CJ-3B production in the 1960s. International licenses and derivatives The CJ-3B design was also licensed to a number of international manufacturers, which produced a civilian and military variants long after 1968, including Mitsubishi of Japan and Mahindra of India. Mitsubishi's version was built from 1953 until 1998, while Mahindra continued to produce vehicles based on the Willys CJ-3B until October 1, 2010. The CJ-3B was also built by Türk Willys Overland in Tuzla county of Kocaeli city. It was the first off-road vehicle plant to be opened in Turkey, in 1954. It was produced under Tuzla 1013 brand. Mahindra's "Mahindra CJ" produced in two versions: four-seater CJ 340 and six-seater CJ 540. Both were equipped with Peugeot-sourced engines. Mitsubishi Jeep The Jeep was introduced to the Japanese market as the Jeep J3 in July 1953 after Willys agreed to allow Mitsubishi to market the car, competing with the Nissan Patrol and the Toyota Land Cruiser.
