China's Tengzhong may finalise a deal with General Motors Co [GM.UL] on Friday to acquire the U.S. automaker's Hummer business for about $150 million, a source familiar with the deal said.

GM and Tengzhong may close the deal as early as today, the source with knowledge of the talks between the two sides told Reuters.

Sichuan Tengzhong Heavy Industrial Machinery has been in detailed negotiations with GM since it announced a plan in June to acquire the rights to the premium off-road Hummer brand from its U.S. owner. (Reporting by Fang Yan and Edmund Klamann, editing by Leslie Gevirtz)
