HONG KONG, Sept 14 (Reuters) - The Hong Kong-listed shares of Chinese electric vehicle (EV) makers fell on Thursday after the European Commission launched an investigation into Chinese subsidies for EVs, escalating tensions between Beijing and the EU.

Hong Kong shares of market leader BYD slid more than 3%. Smaller rival Xpeng fell 0.6%, while Nio was down more than 2% and Geely Auto dropped more than 1%.
