BYD placed fourth among individual brands, with 33,913 registrations and a 6.1% share. Omoda Jaecoo registered 26,463 vehicles, narrowly ahead of MG’s 26,401; each represented 4.8% of the market.

The report also groups some marques by parent company. BYD and Denza together reached 34,889 registrations, while Chery’s Omoda, Jaecoo, Chery and Lepas brands totalled 34,187. Changan’s brands, including Avatr, combined for 17,392, and GAC’s marques totalled 17,127. GWM’s Tank, Ora, Haval, Wey and Poer brands collectively recorded 15,581.
