The Audi e-tron GT - design meets aerodynamics

Aerodynamics is not just a means to an end in the e-tron GT, but an important design feature. The design, with its cd value of 0.24, looks like it was shaped by the wind - and it is. It was created in close collaboration between designers and aerodynamicists. The air intakes in the lower area of the front play a major role. The upright air curtains on the outside direct the air into the wheel arches in such a way that the flow is close to the wheel and then to the flank. Lightweight aero blades are fitted to some of the 20- and 21-inch rims and are only 2 to 3 millimeters thick - this covering further increases aerodynamic efficiency. A controllable cooling air intake (SKE) is located behind each of the large ribs under the headlights and behind the openings in the corners of the single frame, ensuring active aerodynamics. For the sake of efficiency, the two SKEs remain closed as often as possible. When they open during dynamic driving, Y-shaped ducts send air to the radiators and into the front wheel arches to cool the brakes. The second major factor in the active aerodynamics concept is the rear spoiler, which extends electrically in two different positions depending on speed. It works closely with the smooth-surfaced underbody, which ends in a wide diffuser. As a result, the flow at the rear is cleanly dissipated, while at the same time lift at the rear axle is almost completely compensated for at high speed. When the adaptive air suspension (standard on the RS model ) lowers the body, it enhances this effect: airflow and driving stability are improved even further, and lift is reduced even further.
