With a coefficient of drag (Cx) of 0.21, Audi has produced its most aerodynamic car ever. A concrete step towards greater electric efficiency. The new A6 e-tron Sportback boasts an extremely low coefficient of drag, making it one of the most aerodynamic cars on the European market – and the most aerodynamic ever produced by the Volkswagen Group.
A body that approaches aerodynamic perfection
To put this figure into perspective, the lower the Cx, the less air resistance the vehicle encounters. The result: lower energy consumption, and therefore greater range. By way of comparison, a combustion saloon like the Audi RS6 has a Cx of around 0.35, while the Tesla Model S, often cited as a benchmark, has a Cx of 0.20…
2,800 simulations, 1,000 hours in the wind tunnel: the quest for detail
Audi has left nothing to chance. To achieve this level of aerodynamic finesse, the brand carried out 2,800 digital simulations, followed by 1,000 hours of wind tunnel testing. Every detail of the bodywork was studied, rethought and optimised.
Notable innovations include:
- Smoothed rims, designed to reduce turbulence around the wheels.
- A lower body equipped with air deflectors, which channel the air and guide it fluidly under the car.
- A flat bottom coupled with a refined rear diffuser, accelerating airflow to reduce drag.
All these improvements give the new A6 2025 a silhouette worthy of a drop of water in the air, naturally the most aerodynamic shape.
750 kilometres of range: when form meets function
Beyond the raw numbers, this quest for efficiency is reflected in concrete terms on the road. Thanks to its advanced aerodynamics and optimised energy management, the A6 e-tron Sportback is claimed to have a range of up to 750 kilometres. A symbolic threshold that repositioned Audi as a serious player in top-of-the-range electric competition.
A strong signal for the future of electric mobility
With this saloon, Audi confirms that the future of electromobility lies not only in batteries and engines, but above all in the shape of the vehicles themselves. In the all-electric era, the bodywork is becoming a key element of performance. So the A6 e-tron Sportback is more than just a styling exercise: it’s the symbol of a strategic shift, where every hundredth of a Cx becomes a kilometre gained.
