The robust growth was wholly credited to the 257.62% hike in new energy vehicle (NEV) sales. Notably, the sales of new energy passenger vehicles (NEPVs) zoomed up 276.4% over a year ago to 70,022 units last month, which made the year-to-date NEPV sales top 300,000 units.

Of the NEPVs sold in Sept., 33,716 units were DM models (namely, PHEVs), representing a 427.55% remarkable increase year-over-year thanks to the driving forces from the DM-i models.

With 15,164 units sold, the Qin PLUS DM-i accounted for 45% of the BYD DM models Sept. sales. Meanwhile, the sales of the Tang DM, the Song DM, and the Han DM reached 10,278, 5,822, and 2,452 units respectively.
