A BMW i5 electric car rolled off the assembly line on Wednesday in northeast China's Shenyang, the capital city of Liaoning Province, marking the 6 millionth car produced by BMW Group's joint venture in China, BMW Brilliance Automotive (BBA).

This came just 15 months after the joint venture's 5 millionth car was produced.

The German carmaker announced in April an additional investment of 20 billion yuan (about 2.8 billion U.S. dollars) in the production base in Shenyang.

The carmaker said the investment will be used for upgrading and innovating the Dadong plant of BBA, which was founded in 2003.

In 2023, the BMW Group delivered a total of more than 820,000 BMW and MINI vehicles in the Chinese market, accounting for about 32 percent of its global sales.
