Which has a longer lifespan, Wuling or Changan?

Based on the current situation, Wuling, which has been engaged in the commercial vehicle field for many years, has better lifespan and quality in its commercial vehicle products compared to Changan. Moreover, Wuling commercial vehicles have accumulated a deeper reputation. However, in the passenger vehicle sector, Changan clearly has more advantages, with several of its main models having withstood the test of the market and consumers, earning a good reputation for quality and lifespan. More relevant information is as follows: Note 1: Before 2019, the reason Changan couldn't outsell Wuling was that Wuling almost monopolized the commercial MPV market, with the Wuling Hongguang becoming the best-selling model in China. However, starting from 2017, the gap between the two began to narrow as Changan began to focus on the passenger vehicle market, launching models like the Yidong DT and Changan CS55 to establish a foothold in the market. At that time, Wuling had not made significant moves in the passenger vehicle sector, and the iconic Wuling Hongguang was even discontinued. Although the Baojun brand was involved in passenger vehicles, its models had strong commercial vehicle characteristics. Note 2: From 2018 to 2019, Changan increased its investment in the passenger vehicle sector, launching models like the Changan CS55PLUS, Changan CS75PLUS, and Changan UNI-T, which could compete with joint-venture rivals. In contrast, although Wuling launched the new Baojun brand in 2019 with a determination to focus on passenger vehicles, Changan had already set the stage by then. Therefore, it was natural for Changan to surpass Wuling in 2019.
