Mr. Alain Klein, Powertrain and Chassis Director of China Tech Center of PSA Peugeot Citroen, mentioned that facing the phenomenon of global warming, many countries in the world have issued new policies to encourage the development of low-emission vehicles. For years, PSA Peugeot Citroen has made a great progress in the area of clean vehicles. Hybrid technology costs a lot, which needs the government to further issue related regulations and encouraging methods to stimulate their development. In addition, the development of hybrid vehicles should be in connection with the situation of urban road and highway. And the energy-saving of hybrid vehicles expressed themselves clearly in city driving.
