Making mobility more and more sustainable is a continuously strengthening social demand which has gained a permanent place in the product specifications of car manufacturers and suppliers. In the roof area Webasto focuses here primarily on lightweight design. Against a background of increasingly strict limit values for CO_2 emissions and due to the increasing popularity of electric vehicles, weight-saving is becoming more and more important. A rule of thumb is that a weight reduction of 100 kilograms results in a reduction in carbon dioxide emissions of 3.5 g/km for vehicles with petrol engines and 3.0 g/km for diesel vehicles. Gains are also made in agility and thus more driving pleasure. Bearing in mind that if weight were unchanged this additional agility would require higher performance (so-called performance compensation), the comparison actually indicates a reduction in carbon dioxide emissions of approximately 8.5 g/km.
