Audi A6 Sportback e-tron – The Thrilling Aerodynamics Journey

The Audi A6 Sportback e-tron, with a drag coefficient (Cd) of , is the most aerodynamic model ever made by the car manufacturer and is at the top of the VW Group in terms of aerodynamics for its segment. The Audi A6 Avant e-tron2 also achieves an excellent Cd value of , placing it at the top of its class. These results were achieved thanks to the work of the aerodynamics developers and designers, who worked together with great attention to detail to achieve these record values. Aerodynamics have always played a key role in the history of Audi. As early as 1967, the NSU Ro 80 model, with its wedge-shaped body, already had a Cd of , a value that represented a turning point in automotive design at the time. Later, the third-generation Audi 100 (C3), launched in 1983, improved further with a Cd value of , a remarkable result for its time. The story continued with the third-generation Audi 80 (B3), which achieved a drag value of . Today, the new A6 e-tron12 continues this tradition, confirming Audi’s commitment to finding the perfect balance between aesthetics and functionality. The achievement of such low Cd values ​​for the A6 Sportback e-tron and the Avant e-tron was made possible by careful optimization of the body shape and vehicle components. The entire process required around 2,800 simulations and many hours of wind tunnel testing. The main goal of the project was to maximize the aerodynamic efficiency and range of the vehicles. This was achieved through numerous iterations between virtual simulations and physical model tests, which led to continuous design improvements. The focus was on specific elements of the body, such as the basic proportions, the slim line of the upper part of the cabin and the sloping roof, which help reduce aerodynamic drag. Numerous millimetre-by-millimetre changes were made to improve the airflow around the car, such as the air curtains that improve the airflow at the front of the car. Other elements, such as the width of the rear track and the side aerodynamic frames, were also optimised to achieve a significant improvement in aerodynamic performance. These optimisations allowed the vehicle’s range to be increased by several kilometres, demonstrating that even small details can have a big impact on overall performance. In addition, the project paid particular attention to the underbody configuration, which is crucial to the vehicle’s aerodynamics. The addition of elements such as rear diffusers, spoilers and specific underbody covers have helped to further improve the Cd value. Various measures, such as the use of 3D bumpers and wheel spoilers, have been used to optimize airflow and reduce drag. The wheels of the Audi A6 e-tron have been designed with an innovative approach, focused on aerodynamics. The alloy wheels, in addition to meeting stability requirements, have been developed to maximize aerodynamic efficiency, reducing turbulence and improving airflow around the vehicle. The materials and design of the wheels, such as the inclusion of aerodynamic blades, have also been studied to contribute to better overall aerodynamics. In short, the success achieved with the Audi A6 e-tron in terms of aerodynamics is the result of meticulous and detailed work on every single element of the vehicle design, combining advanced engineering, technology and in-depth collaboration between the development and designer teams. 🙏 If this video was useful to you, make a donation with the “Thanks“ button or subscribe to support it: ⚡️ Discover ALL the new cars before anyone else!
