The body of the A6 L e-tron concept is identical to that of the Audi A6 L. It is lightweight, rigid and safe to a maximum degree, due to application of the ultra lightweight principle. Consisting of approximately ten percent aluminum, it weighs about 15 percent less than a comparable all-steel design. Aluminum components in the load-bearing structure and exterior skin, as well as the high-tech steels used in the occupant cell, make the body significantly lighter.
Each new future Audi model will be lighter in weight than the previous model. This makes the brand a frontrunner in reversing the upward weight spiral. In designing car bodies, developers will intelligently use new combinations of materials, including carbon fiber-reinforced polymer (CFRP). For Audi, ultra lightweight construction does not solely focus on one material, rather it seeks a flexible approach that utilizes a wide variety of materials – but with one goal: to attain the best performance with the least material usage at the best places.
Furthermore, advanced materials and construction methods achieve an extremely low sound level in the interior of the Audi A6 L e-tron concept. Excellent vibration comfort is attained by fine-tuning components and by hydraulically damping axle and drive mounts.
Audi’s ultra lightweight construction competence is also found in the chassis, which combines a high level of comfort with sporty handling. The links are made of aluminum. The power steering, like the brake booster and the air conditioning compressor, utilizes an electromechanical drive.
At the limits of performance in driving through curves, the electronic transverse differential lock – a function of electronic stabilization control (ESC) – stabilizes the Audi A6 L e-tron concept by making small interventions at the front wheel on the outside of the curve.
