SHANGHAI, May 28 (Reuters) - China's BYD on Tuesday launched its latest generation of plug-in hybrid technology that achieves a record low fuel consumption of 2.9 litres per 100 km (62.1 miles) on depleted batteries.

BYD Chairman Wang Chuanfu unveiled the technology while speaking at an event in Xian, the capital of Shaanxi province, the site of the company's first automaking factory after it acquired Qinchuan Automobile Co in 2003. (Reporting by Zhang Yan, Casey Hall; Editing by Jan Harvey)
