Hybrid Electric Vehicle (HEV) Concepts

Hybrid vehicles offer a further chance to reduce fuel consumption and emissions. Some vehicles are on the market already, and many companies are working on different solutions. The chosen technology influences very much the overall result for actual operation, because differences in efficiency and weight have to be considered. Also the vehicle investment cost depending on the chosen complexity should be taken into account. The question about the degree of complexity will be discussed with regard to additional manufacturing costs, by evaluating and highlighting the technical as well as the commercial background.

Today’s discussion about sustainable technologies concerning emission reduction, fuel saving potential and carbon dioxide reduction (CO2) respectively, treats often two subjects: alternative fueled ICEs, especially compressed natural gas (CNG), and hybrid electric vehicles (HEV), which besides the high fuel saving potential, bring further benefits for our society. Throughout the motored vehicle evolution, there have always been concept and prototype cars combining the advantages of two different propulsion systems, which include a second power source and energy storage device to supplement the fuel tank.
