The Audi e-tron will stand out for its aerodynamics and virtual rear-view mirrors

7 Jun


It seems that aerodynamics will remain a key parameter in the cars of the future. We all know that SUVs are not vehicles that stand out in this aspect due to their external dimensions (mainly at their height). The Audi e-tron prototype wants to change that and promises a production version that is really capable in this regard. In fact, it will mark a new reference among the cars in its class.

The electric promises an aerodynamic coefficient of 0.28 CX, with the SUV achieving a lower value. This data is more important than it may seem at first glance. With a resistance to the advance so reduced is achieved that there is not so much waste of energy. In practice, it could be translated with an increase in autonomy of about 35 kilometers compared to an electric one with a worse aerodynamic coefficient.

In this way and with its 95 kWh battery, the Audi e-tron prototype achieves more than 400 kilometers of autonomy (according to WLTP cycle) of which we have already spoken. The key to achieving such a small value has been the previous work of 1,000 hours in the wind tunnel of the brand in Ingolstadt. These facilities consist of a rotor of 5 meters in diameter that can generate winds of up to 300 km / h thanks to its power of 2.6 megawatts.

After the hours in the wind tunnel they began to try solutions with the aim of reducing the aerodynamic coefficient. The most striking are the new virtual rear-view mirrors, because it would be the first production vehicle to carry them. They replace the traditional mirror with cameras that project the images on small OLED screens inside. In this way you can reduce the surface of the mirror, the total width of the vehicle and aerodynamic noise.

Continuing with the technical innovations that will incorporate the Audi e-tron prototype, highlights the active aerodynamics. After the single-frame grid there are some electrically controlled slats that allow or prevent the passage of air depending on the needs. On the sides there are four additional ventilation ducts and even the wheels and wheels have an aerodynamic design. To finish, we must talk about low fairings and with a texture similar to that of a golf ball or pneumatic suspension as standard to reduce the height of the body by 26 mm compared to the normal position.
