AM GM was sold by AMC as an independent company on 1983, because the French state-owned Renault was interested in investing in AMC at that time, and the US government did not want the defense contract to fall into the hands of foreign manufacturers.
Jeep's famous products in World War II were later introduced to CJ Jeep for civilian use. The new model 1987 was renamed as herdsman, and 1997 introduced an improved version, which restored the traditional round headlights. The appearance has not been changed much, but the wind resistance coefficient has been reduced from 0.63 to 0.55, and the leaf spring in the chassis suspension system has been replaced by hydraulic spring. In 2007, the drag coefficient of herdsman was reduced to 0.49. There are many electric control devices in the machine, including the special front suspension electronic rollover bar. When the wheel needs more up-and-down travel, the connection between the rollover bar and the two front wheels can be cut off.
1984, Jeep introduced the Cherokee sedan with the characteristics of both cars and off-road vehicles, which was very popular in the market. In 1980s, Jeep became the only profitable brand of AMC. 1987 Chrysler acquired AMC, which was changed to Eagle, and the Jeep brand remained the same. In the1980s, Jeep Cherokee promoted the popularity of sport utility vehicles (SUVs) in the United States, and many automobile factories also introduced sport utility vehicles, including Porsche and other automobile factories that had never produced SUVs before.
The Grand Cherokee is a brand-new model, which was put on the market to stop Ford explorers.
