Detailed description How to combine a concern for the environment while still wanting to buy a car. For years Eckard Helmers has been studying mobility and pollution. In order to understand how we have reached the present situation, he tells the story of the automobile from the first prototype to the "oil shock" of 2008. He explains in detail which pollutants the traditional combustion engine produces alongside CO2, and how politicians, lobbyists and environmental conservationists argue over their definition and limits. He clarifies the pros and cons of biofuels and fuel cells and pleads convincingly for liquid- or natural-gas powered cars. Finally he conjures up a vision of a mobile future, where electrical drive units play a central role. Alongside practical tips and help in decision-making for consumers he calls for a fundamental change in perception - among buyers and automotive manufacturers alike.
