Residents of large cities suffer greatly from air pollutants, a significant proportion of which is accounted for the road transport. In order to solve this issue, car manufacturers are upgrading internal combustion engines, designing alternative engine units. This article analyzes various modern engine units, highlights their strengths and weaknesses. Statistical data demonstrating the growth of production and sales of electric and hybrid vehicles in Russia and abroad are presented. Cars equipped with traditional internal combustion engines (ICE) have unique advantages and today make more than 99 % of the global fleet. Based on the analysis, a scheme of a hybrid power plant (HPP) was formed, combining the components of engine units of electric vehicles and internal combustion engines. The main elements of installation and their layout in the car are described. A schematic diagram of transmission is presented, its components are listed and their operation is described. The HPP scheme was developed within the framework of the concept of a motor vehicle corresponding to the trends of modern automotive industry. At the same time, such cars provide the opportunity of sport driving experience, have good dynamic performance.
