Led by the redesigned F3 compact sedan and new models such as the L3 compact car and the S6 SUV, BYD's auto sales rose 15 percent year-on-year to 38,015 units in September, according to J.D. Power and Associates.

BYD's third-quarter net profit also rebounded after tumbling 89 percent year-on-year in the first six months.

Thanks in part to rebounding auto sales, BYD's net profit surged nearly 600 percent year-on-year in the third quarter to 77 million yuan ($12 million), according to the company.

BYD, headquartered in the south China city of Shenzhen, is partly owned by Warren Buffett's Berkshire Hathaway Inc.
