Abstract: In this paper, the development trend of various energy-saving technologies in the future is studied and judged through in-depth analysis of relevant data of various energy-saving technologies for passenger cars, and help industry enterprises scientifically choose the development path of energy-saving technologies. In general, the rapid application of technologies such as turbocharging, in cylinder direct injection, three cylinder engine, idle start stop, and advanced transmission has played a important role in the development of energy saving vehicle in the past five years. However, as the carrying rate of these energy saving vehicle technologies tends to saturate, enterprises need to further reduce the average fuel consumption level of automobiles by developing 48 V and hybrid electric vehicle (HEV) and other electrification technologies, and the industry chain needs to make corresponding layout in advance.
