Audi A6 Sportback e-tron – Efficiency technologies and Aerodynamics
Best in class: outstanding aerodynamics
Superior aerodynamics is a core component of the long history of successes for Audi. The aerodynamic heroes of the past, such as the Audi 100 (C3) and the Audi 80 (B3), also belong to the mid-size segment.
The legendary cw value of the third-generation Audi 100 meant it was called the "aerodynamics world champion of all classes". With a Cw-value of 0.30, Audi outclassed its competitors in 1982
- and continued to do so for many years. Today, the Audi A6 e-tron* is writing a new chapter in this success story. At Audi, sporty design and aerodynamics do not contradict each other: Optimal basic tuning and numerous detail optimizations contribute to excellent aerodynamics and ensure an exceptionally low w value of 0.21 for the Sportback, making it the best Audi of all time in terms of aerodynamics and the most aerodynamic vehicle in the entire VW Group. The Avant also achieves a very good w value of 0.24, making it one of the best in its segment.
The front is aerodynamically optimized and has air curtains that positively influence the flow around the front and the wheels. The greenhouse is extremely slim, and the roofline slopes towards the rear. Moreover, a controllable cool-air intake under the Singleframe of the Audi A6 e-tron* ensures the airstream can flow around this zone with minimal losses. Audi has further optimized this system with additional components. The underbody also plays a vital role in the aerodynamics concept through a high degree of sealing and small optimizations of various components. These include specially adapted wheel trims and 3D bumps ahead of the front wheels, which are individually optimized for the Sportback and Avant, the undertray, the battery, the rear axle, and sill panels. A wide and aerodynamically optimized diffuser achieves the optimum balance between lift at the rear axle and u value. The Avant is also equipped with an additional spoiler on the diffuser. Aero elements in the form of side spoilers at the rear of the A6 Avant e-tron* enable controlled stall. The low roof edge spoiler contributes to a small "still water area" behind the vehicle, which also improves the aerodynamics.
Aero optimizations offered by some of the wheels of various sizes round off the aerodynamic concept. For example, an attractive 21" aero wheel with plastic covers is offered. The optional virtual exterior mirrors are among the proven aerodynamic components that are already familiar from the Audi Q8 e-tron*. Their second generation is used on the Audi A6 e-tron*, and they can now fold electrically. The compact cameras have a flow-optimized shape, which reduces the front area of the vehicle and improves the drag coefficient.
