Audi A3 Sedan – Aerodynamics
The aerodynamics benefit from the higher rear end compared with the predecessor as well as the large diffuser. As a result, the new A3 Sedan with the 2.0 TDI 110 kW (150 PS) achieves a Cd value of 0.25 and is therefore 0.04 Cd points better than the first generation.
The controllable cooling-air inlet with two electrically actuated louver modules behind the Singleframe also contribute to this. They regulate the flow of air intelligently and according to the situation. In addition, the paneled underbody, the exterior mirrors with improved aerodynamics, and the active brake cooling reduce air resistance and make for a streamlined vehicle.
