The sales figure should include 's vehicles, which sold a record 10,628 units in September.

Jianghuai Automobile Group (JAC), NIO's auto manufacturing partner, sold 14,400 pure electric passenger vehicles in September, the company said in figures released Monday.

That's up 163 percent from 5,477 in the same month last year and up 78 percent from 8,075 in August.

JAC didn't specify, though as is industry practice, its electric vehicle (EV) sales figures should include NIO vehicles.

NIO delivered a record 10,628 vehicles in September, exceeding the 10k threshold for the first time, up about 126 percent from a year ago and up about 81 percent from August.

This means that JAC's own brand of EVs sold 3,772 units in September.

JAC's data also showed that it had cumulative EV sales of 90,093 units from January to September, up 190 percent from 31,017 a year ago.

NIO's cumulative deliveries from January to September were 66,395 units, according to the company.

JAC signed a five-year contract with NIO in 2016. The two signed a contract to establish Jianglai Advanced Manufacturing Technology (Anhui) Co on March 27 this year.

In late May, NIO said it had renewed its manufacturing contract with JAC from May 2021 to May 2024, and that JAC would continue to produce the ES8, ES6, EC6, ET7 and possibly other NIO models.

JAC will expand its annual production capacity to 240,000 units to meet NIO's growing demand, the company said in a statement in May.
