Audi is expanding an additional core competence - ultra lightweight construction. Aluminum is already used according to the ASF (Audi Space Frame) principle in many models today to reduce the weight of the bodies by roughly 40 percent. The material improves the environmental balance: the fuel savings it enables more than offsets the greater amount of energy required for its production. For example, the intensive lightweight construction measures used on the Audi A6 already pay off after a distance of around 5,000 kilometers (3,107 miles).

In the future, each new Audi model will continue to be lighter - in some cases much lighter than its predecessor. The development engineers will intelligently combine new materials, including carbon fiber-reinforced polymer (CFRP), in the bodies. At Audi, lightweight construction means the flexible use of various materials, always with the aim of using the least possible amount of the right material in the right place. In the intelligent composite construction, the selection and use of materials and their influence on the overall energy balance plays a crucial role. At Audi, an intelligent mix of different materials always also takes into account the effects on the environment and resources.
