Seres sold 42,176 new energy vehicles in July, up 508 percent from the same month last year, said the Chinese vehicle maker on Thursday.

Its sales in July brought total deliveries in the first seven months this year to exceed 243,000 units, marking a 370 percent surge year-on-year.

The sales performance is primarily driven by the AITO brand codeveloped with Huawei, a Chinese technology giant.

The AITO brand's cumulative sales reached 400,000 units in late July, just 28 months since its first vehicle rolled off the assembly line.

AITO's flagship model, the M9, has seen its deliveries to exceed 70,000 units so far. The popular M7's cumulative sales hit 200,000 units by the end of July.
