State-of-the-art body and aerodynamics

The passenger cell of the new S3 models is made from hot-formed, ultra-high-strength steel and hence forms a strong compound. The components make up around 30 percent of the weight of the body shell. The engine hood is made of aluminum. The body is extremely crash-resistant, rigid, and acoustically comfortable. Thanks to careful soundproofing and sophisticated aeroacoustics, it is always quiet inside the car.

Audi’s developers have optimized many areas of the body in order to improve the aerodynamics. One innovative feature is the brake cooling with a neutral drag coefficient, where the air is guided from the engine compartment through the wheel arch shell to the brakes. This solution is more aerodynamically efficient than the conventional air duct from the underbody. In the new S3 models it is almost entirely paneled to ensure low air resistance. At the rear, a diffuser reduces rear axle lift. In the case of the S3 Sedan, it combines with the rear spoiler to ensure that the air flow is broken down in a defined manner without creating disruptive vortexes.
