Aerodynamics Q4 Sportback e-tron Animation

Detailed solutions, in which Audi aerodynamicists worked closely with the designers, provide further range gains. At the front of the vehicle there are narrow vertical webs under the headlights - they act as a spoiler and guide the airstream so that it flows cleanly along the side of the vehicle. This effect accounts for five kilometers. A tiny step on the outside mirror caps with a radius of 0.5 millimeters allows the flow to stay there longer. This so-called turbulator edge has an effect similar to the dimples in a golf ball: it ensures a targeted swirling of the air, which has a positive effect on aerodynamics and is good for two kilometers of range.
