It looks like it is a gasoline car.
Hongqi (and it buyers) is incredibly conservative in this sense. I wonder why Xi and his lieutenant can't switch to EVs given the proven success of China's EV industry. If Xi were to drive a EV Hongqi or other Chinese homegrown EV brands, that would signal confidence and help support the country's entire EV industry, which is already a symbol of the country's tech prowess. Also, for example, if the Guangdong MPS were to order bunch of BYD Yangwang U8s (for its quasi-amphibious capabilities in shallow waters) to replace those old early 2000s Volkswagen and Honda police cars still in use, that could also signal the Party's support for the country's EV industry. One thing weird about China's bureaucracy is that governmental vehicles are still comprised of cheap Japanese and German gas guzzlers from the 1990s and 2000s.
