but independently developed vehicles are quickly replacing them. These small cars carry the Changan brand name although Suzuki technology is used in their design and manufacture. On 4 September 2018, Suzuki transferred its 50 percent stake in Changan Suzuki to Chang'an Automobile Group, ending 25 years of joint venture. Under the plan, Chang'an would continue to make and sell Suzuki-branded cars in China under license. In 2021, Changan Suzuki was renamed to Chongqing Lingyao Automobile. Production and research facilities Domestic Changan has four major production bases (in the City of Chongqing, Hebei province, Jiangsu province, and Jiangxi province), eleven automobile production bases, and two engine production bases in mainland China for a more-current total of 21 vehicle-making bases including newer sites in Anhui province, Guangdong province, Heilongjiang province, Shandong province, and Shanxi province. Anhui A planned 300,000 units/year capacity mini-vehicle production base in Hefei, Anhui province, should see completion in 2011.

Hebei An industrial park in Hebei province may continue to be Chang'an controlled. Heilongjiang A Harbin, Heilongjiang province, R&D center, is now a Chang'an asset. It may have been owned by Hafei prior. Jiangsu A Chang'an-Ford plant and an industrial park in Nanjing, Jiangsu province, may comprise Chang'an operations in this province. Jiangxi A planned Chang'an commercial vehicle production base in Nanchang, capital of Jiangxi province, will produce JMC and Ford-branded vehicles and join an R&D center as a second facility in this province. The latter facility may be a former Changhe asset. Shanghai Chang'an has an R&D center in this coastal city.
